'PromptQuest' is the worst game of 2025 (trying to make chatbots work)

www.theregister.com - Comments

Opinion When Microsoft recently decided to open source the seminal text adventure game Zork, I contemplated revisiting it during the festive season... until I realized I've spent much of 2025 experiencing the worst of such games when using AI chatbots.

Adventure games like Zork and its many imitators invited players to explore a virtual world, often a Tolkien-esque cave, that existed only as words.

"You enter a dark room. A Goblin pulls a rusty knife from its belt and prepares to attack!" was a typical moment in such games. Players, usually armed with imagined medieval weapons, might respond "Hit Goblin" in the expectation that phrase would see them draw a sword to smite the monster.

But the game might respond to "Hit Goblin" by informing players "You punch the Goblin."

The Goblin would dodge the punch and stab the player with the rusty knife.

Game over... until the player tried "Hit Goblin with sword" or "Stab Goblin" or whatever other syntax the game required, assuming they didn't just give up out of frustration at having to guess the correct verb/noun combination.

Adventure games were big in the 1980s, a time when computers were flaky and unpredictable, and AI was an imagined technology. Games that required obscure syntax were mostly tolerable and generally excused.

I'm less tolerant of AI making me learn its language.

For example, I recently prompted Microsoft's Copilot chatbot to scour data available online and convert some elements of it into a downloadable spreadsheet. The bot accepted that request and produced a Python script that it claimed will write a spreadsheet.

In other AI experiments, I have found that the same prompt produces different results on different days. One prompt I use to check I haven't left any terrible typos in stories produces responses in a different format every time I use it. Microsoft has also, in its wisdom, decided to offer different versions of Copilot in Office and in its desktop app. Each produces different results from the same prompt and the same source material.

Using AI has therefore become a non-stop experiment in "Hit/Kill/Stab/Smite Goblin."

And when Copilot starts using a new model, which it does without any change to its UI, prompts that worked reliably in the past produce different results, meaning I need to relearn what works.

My point here is not that chatbots do dumb things and make mistakes. It's that working with this tech feels like groping through a cave in the dark – a horrible game I call "PromptQuest" – while being told this is improving my productivity.

After Copilot gave me a Python script instead of a spreadsheet, I played a long session of PromptQuest during which Microsoft's AI responded to many different prompts by repeatedly telling me it was ready to make a spreadsheet, would make it available to download, and had completed the job to my satisfaction.

It never delivered the spreadsheet, and my frustration grew to the point at which I instructed Copilot to produce a progress bar so I could see it work.

You can see the results above. Ironically, I think it looks a lot like the output of a text adventure game. ®

Building a macOS app to know when my Mac is thermal throttling

stanislas.blog - Comments

This is the story about how I built MacThrottle.

I’ve been very happy with my M2 MacBook Air for the past few years. However, when using an external display, especially a very demanding one like a 4K 120Hz display, I’ve noticed it started struggling more. Since it lacks fans, you can’t hear it struggling, but you can feel it as everything becomes very slow or unresponsive: that’s when thermal throttling kicks in.

I know it’s thermal throttling because I can see in iStat Menus that my CPU usage is 100% while the power usage in watts goes down.

It’s even more obvious with MX Power Gadget: You can see the power usage and frequency of the performance core dropping, as usage keeps being 100%:

MX Power Gadget

Getting the thermal state programmatically #

This was a wilder ride than I expected. It’s possible to know programmatically if the Mac is throttled, because macOS exposes this in various but inconsistent ways.

The approach that Apple recommends is to use ProcessInfo.thermalState from Foundation:

~ swift -e 'import Foundation; print(["nominal", "fair", "serious", "critical"][ProcessInfo.processInfo.thermalState.rawValue])'
nominal

Sounds good, right? However, I knew that another tool could provide this information, though it needed root: powermetrics.

➜  ~ sudo powermetrics -s thermal

Password:
Machine model: Mac14,2
OS version: 25B78
Boot arguments:
Boot time: Sun Nov 23 10:19:29 2025



*** Sampled system activity (Wed Dec 17 09:48:34 2025 +0100) (5001.07ms elapsed) ***



**** Thermal pressure ****

Current pressure level: Nominal


*** Sampled system activity (Wed Dec 17 09:48:39 2025 +0100) (5001.25ms elapsed) ***



**** Thermal pressure ****

Current pressure level: Nominal

(yes the output has that many newlines)

Both report the pressure level to be “nominal”, they must be the same…right?

After running a few stress tests stress-ng --cpu 0 -t 600, I started to see the two values diverge!

For some reason, the granularity is different between ProcessInfo.thermalState and powermetrics. They have a different amount of possible states and they don’t line up.

Here is my empirical experience:

ProcessInfo.thermalStatepowermetrics
nominalnominal
fairmoderate
fairheavy

I never managed to hit these states, so I don’t know if they match, but they’re technically defined:

ProcessInfo.thermalStatepowermetrics
serioustrapping
criticalsleeping

In practice, when my Mac starts getting hot, from the powermetrics perspective it goes into moderate, and when it starts throttling, it goes into heavy. The problem is that with ProcessInfo, both are covered by the fair state, so it’s not really useful to know when the Mac is actually throttling. ☹️

I thought maybe this was an iOS vs macOS thing? But Apple references it in the macOS docs as well. Maybe it was more consistent on Intel Macs?

I stumbled upon this article from Dave MacLachlan, a Googler working on Apple stuff, in 2020. I learned that there are other CLI tools to get thermal data, but they don’t seem to work on my Apple Silicon MacBook:

➜ sudo thermal levels
Thermal levels are unsupported on this machine.
➜ sudo pmset -g thermlog
Note: No thermal warning level has been recorded
Note: No performance warning level has been recorded
Note: No CPU power status has been recorded
^C

I also learned that the data powermetrics shows is actually coming from thermald. And thermald writes the current thermal pressure to the Darwin notification system (notifyd)!

➜ notifyutil -g com.apple.system.thermalpressurelevel

com.apple.system.thermalpressurelevel 0

The cool thing here is that it doesn’t require root!

It turns out I can subscribe to a Darwin event to get the (good) thermal state!

Here is a snippet to get it in Swift:

import Foundation

@_silgen_name("notify_register_check")
private func notify_register_check(
  _ name: UnsafePointer<CChar>, _ token: UnsafeMutablePointer<Int32>
) -> UInt32
@_silgen_name("notify_get_state")
private func notify_get_state(_ token: Int32, _ state: UnsafeMutablePointer<UInt64>) -> UInt32
@_silgen_name("notify_cancel")
private func notify_cancel(_ token: Int32) -> UInt32

let notifyOK: UInt32 = 0
let name = "com.apple.system.thermalpressurelevel"

var token: Int32 = 0
let reg = name.withCString { notify_register_check($0, &token) }
guard reg == notifyOK else { fatalError("notify_register_check failed: \(reg)") }
defer { _ = notify_cancel(token) }

var state: UInt64 = 0
let got = notify_get_state(token, &state)
guard got == notifyOK else { fatalError("notify_get_state failed: \(got)") }

let label =
  switch state {
  case 0: "nominal"
  case 1: "moderate"
  case 2: "heavy"
  case 3: "trapping"
  case 4: "sleeping"
  default: "unknown(\(state))"
  }

print("\(state) \(label)")

Prints:

➜  ~ swift thermal.swift
0 nominal

Now that I had a useful value to work with, it was time to build the app.

Building MacThrottle #

Armed with Opus 4.5, I set out to build a little menu bar app where I could see, at a glance, if my Apple Silicon die was trying to save itself from crossing 110°C. I called it MacThrottle.

I built a simple SwiftUI app for the menu bar that shows me the status in a superbly original thermometer icon. The thermometer is filled depending on the thermal state, and its color changes from green to red. I have like 20 menu bar icons and they’re all monochromatic, so the color in the thermometer is very subtle to keep things consistent.

The app is a simple SwiftUI app. Apple provides a scene called MenuBarExtra to render a menu bar control. It was simpler than I expected! To make it a pure menu bar app with no dock icon, you just need to set LSUIElement to true in Info.plist.

An early version of MacThrottleAn early version of MacThrottle, just reporthing the thermal state

First approach: root helper for powermetrics #

I explained the various approaches to get the thermal pressure level in the previous section. But when I was building the app, I discovered later on that thermald was publishing the thermal state to notifyd. So at first, I thought I had to use powermetrics to get useful thermal state changes. Since that unfortunately requires root access, the app needed root access too.

To reduce the scope of what runs as root, I did not run the app itself as root. Instead, the app does not work by default, but it gives you the option to install a helper. It does this through an AppleScript with administrator privileges to prompt for access.

The helper is just a bash script ran as a launchd daemon:

➜  ~ cat /Library/LaunchDaemons/com.macthrottle.thermal-monitor.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.macthrottle.thermal-monitor</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/mac-throttle-thermal-monitor</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
</dict>
</plist>
➜  ~ cat /usr/local/bin/mac-throttle-thermal-monitor
#!/bin/bash
OUTPUT_FILE="/tmp/mac-throttle-thermal-state"

while true; do
    THERMAL_OUTPUT=$(powermetrics -s thermal -n 1 -i 1 2>/dev/null | grep -i "Current pressure level")

    if echo "$THERMAL_OUTPUT" | grep -qi "sleeping"; then
        PRESSURE="sleeping"
    elif echo "$THERMAL_OUTPUT" | grep -qi "trapping"; then
        PRESSURE="trapping"
    elif echo "$THERMAL_OUTPUT" | grep -qi "heavy"; then
        PRESSURE="heavy"
    elif echo "$THERMAL_OUTPUT" | grep -qi "moderate"; then
        PRESSURE="moderate"
    elif echo "$THERMAL_OUTPUT" | grep -qi "nominal"; then
        PRESSURE="nominal"
    else
        PRESSURE="unknown"
    fi

    echo "{\"pressure\":\"$PRESSURE\",\"timestamp\":$(date +%s)}" > "$OUTPUT_FILE"
    chmod 644 "$OUTPUT_FILE"
    sleep 10
done

The bash script writes the thermal state to a file every few seconds and the app reads it every few seconds!

Using the thermald IPC notifications #

Once I discovered I could use the notification system without elevated privileges, I replaced the helper by code in the app the read the value from the notification system directly. Much simpler 🎉

Temperature and fans #

I wanted to show the temperature and fan speed (when supported) in a little graph in the menu bar app. This would allow me to correlate the thermal state with increased temperature, for example.

Again, there are multiple APIs to read the temperature. First, I started using an undocumented API from IOKit, but I realised I was getting ~80ºC max, while iStat Menus or MX Power Gadget would show >100ºC.

Stats, the open source alternative to iStat Menus, helped me use the SMC instead and get the correct values. But the SMC is a much more unstable API because each SoC has different keys to access the temperature data:

private let m1Keys = ["Tp01", "Tp05", "Tp09", "Tp0D", "Tp0H", "Tp0L", "Tp0P", "Tp0X", "Tp0b"]
private let m2Keys = ["Tp01", "Tp05", "Tp09", "Tp0D", "Tp0X", "Tp0b", "Tp0f", "Tp0j"]
private let m3Keys = ["Tf04", "Tf09", "Tf0A", "Tf0B", "Tf0D", "Tf0E", "Tf44", "Tf49", "Tf4A", "Tf4B"]

Though the M3 keys seem to work on my M4 Max work MacBook Pro&mldr;

I ended up using SMC first to get the accurate temperature and fall back to IOKit if SMC doesn’t work.

Graph in the menu bar #

For the graph, I wanted a compact visualization that would show me the thermal history at a glance.

The graph packs three layers of information:

  • Colored background segments for each thermal state (green for nominal, yellow for moderate, orange for heavy, red for critical)
  • A solid line for CPU temperature with a dynamic Y-axis that adjusts to actual values
  • A dashed cyan line for fan speed percentage (on Macs that have fans)

I didn’t want to spend too much time making a super fancy graph system. Since it polls every two seconds, the graph gets very busy after a while. So I decided to keep it down to 10 minutes, since the thermal state history is mostly interesting short-term.

I also added hover tooltips using onContinuousHover.

When the system was under load, I noticed the graph hovering was not very smooth on my 120Hz display. I found out I can add .drawingGroup to my SwiftUI canvas to use GPU rendering!. Indeed, I added it, and it was smooth again.

MacThrottle showing fan speedGraph with pressure state, temp and fans. Tooltip on hover to get past value is supported.

Adding macOS notifications #

I also added notifications so I get alerted when the state changes, in case I miss the menu bar icon. It can alert on specific state transitions, and optionally on recovery. This is useful to know when it’s time to kill a VS Code instance or a Docker container!

MacThrottle notification alerting of heavy thermal pressureTo be fair, it can get a bit noisy on a struggling Macbook Air&mldr;

It’s true that I usually already notice when the Mac is getting slow, but sometimes the Mac gets slow when it’s swapping heavily. At least now I know when it’s just too hot.

Launching the app at Login #

Of course, I want the app to start automatically now, since it works so well!

I expected that I would need to write .plist again, but no, it’s extremely easy to prompt the user to add a “login item” as macOS calls it, using SMAppService.

SMAppService.mainApp.register()    // enable auto-start
SMAppService.mainApp.unregister()  // disable auto-start
SMAppService.mainApp.status == .enabled  // check current state

How to use it #

Since I don’t have an Apple Developer account, I can’t notarize the app, so installing it from the releases is going to require a few extra clicks in Privacy and Security.

And for Macs that disallow it entirely, building from source with Xcode is the only way. I added instructions in the README.

Hope this is useful to someone else!

Last Year on My Mac: Look Back in Disbelief

eclecticlight.co - Comments

If someone had told me 12 months ago what was going to happen this past year, I wouldn’t have believed them. Skipping swiftly past all the political, economic and social turmoil, I come to the interface changes brought in macOS Tahoe with Liquid Glass. After three months of strong feedback during beta-testing, I was disappointed when Tahoe was released on 15 September to see how little had been addressed. When 26.1 followed on 3 November it had only regressed, and 26.2 has done nothing. Here I summarise my opinions on where Tahoe’s overhaul has gone wrong.

What goes round

Almost all the content displayed in windows is best suited to rectangular views. Images, video, webpages and other text crave areas bounded by right angles. Gentle rounding on the corners, as in Sequoia, is fine, but the significantly increased radius enforced in Tahoe is a misfit. This either leads to cropping of contents, or reduction in size of the view and wasted space.

Cropping is misleading, as seen in this enlarged view of a thumbnail image in the Finder’s Gallery view, compared to the larger version shown below. The thumbnail misrepresents what’s in the original.

Among Apple’s claims for this new look is greater consistency. But two windows in the same app, both created using SwiftUI, can’t even share a common radius, as shown below in Providable running in macOS 26.2.

Out of control

Tahoe has also increased the size of its controls, without using that to improve their clarity. The best way to see that is in my Mallyshag demo app.

This looks good in Sequoia above, but becomes a mess in Tahoe (below) because of its changed control dimensions.

Those three buttons are significantly wider, so now overlap one another and are wider than the text box below. The user sees no benefit to this, though, as the text within the controls is identical.

Iconoclasm

App icons need to be both distinguishable and readily recalled. The first ensures that we can tell one from another, and relies on all the visual cues we can muster, including colours, form and content. Tahoe enforces a rule that everything in the icon must be fitted inside its uniform square with rounded corners, so restricting cues to colours and contents. As a result, the icons of many bundled and other Apple apps have become harder to distinguish in a crowded Dock. Some, including Apple’s Developer app and the App Store, are indistinguishable, while others have degenerated into vague blotches.

Above are most of the apps bundled in Sequoia, and below are those in Tahoe.

Whiteout

In real life, whiteouts are dangerous because they’re so disorienting. There’s no horizon, no features in the landscape, and no clues to navigation. We see and work best in visual environments that are rich in colour and tonal contrasts. Tahoe has continued a trend for Light Mode to be bleached-out white, and Dark Mode to be a moonless night. Seeing where controls, views and contents start and end is difficult, and leaves them suspended in the whiteout.

In light mode, with default transparency, tool icons and text are clearly distinguished tonally, as are some controls including buttons and checkboxes. However, text entry fields are indistinguishable from the background, and there’s a general lack of demarcation, particularly between controls and the list view below.

Wet-on-wet

This technique is used in watercolours to merge layers of colour diffusely, and the best description of some of the results of transparency in Liquid Glass. My examples speak for themselves, and are drawn first from Apple’s own design for System Settings.

Transparency of the Search box at the top of the sidebar on the left renders it incomprehensible when it’s underlaid by scrolled navigational content.

Although the view title Keyboard remains readable, bleed-through of underlying colours is confusing, distracting and aesthetically upsetting.

My next examples show the same window in Providable with a selected list row being scrolled up behind what used to be a window title bar.

With the window in focus, the selection colour overwhelms the traffic light controls and window title, which should read Drop Files. This also draws attention to the limited width necessary to accommodate rectangular content in a window with excessively rounded corners.

Out of focus the selected row is less overwhelming, but traffic lights and title have dissipated in grey blur.

I’m sure that, in the right place and time, transparency effects of Liquid Glass can be visually pleasing. Not only is this the wrong time and place, but those with visual impairment can no longer remove or even reduce these effects, as the Reduce Transparency control in Accessibility settings no longer reduces transparency in any useful way. That was one of the regressions in 26.1 that hasn’t been addressed in 26.2.

Summary

macOS Tahoe’s visual interface:

  • Fits largely rectangular contents into windows with excessively rounded corners.
  • Enlarges controls without any functional benefit.
  • Results in app icons being more uniform, thus less distinguishable and memorable.
  • Fails to distinguish tools, controls and other interface elements using differences in tone, so making them harder to use.
  • Makes a mess where transparent layers are superimposed, and won’t reduce transparency when that’s needed to render its interface more accessible.

Maybe this is because I’m getting older, but that gives me the benefit of having experienced Apple’s older interfaces, with their exceptional quality and functionality.

That was little more than a decade ago, in 2014. Not that I want to turn the clock back, but it would be really helpful if I could read clearly what’s on my display once again.

Hungry Fat Cells Could Someday Starve Cancer to Death

www.ucsf.edu - Comments

Liposuction and plastic surgery aren’t often mentioned in the same breath as cancer.

But they are the inspiration for a new approach to treating cancer that uses engineered fat cells to deprive tumors of nutrition.

Researchers at UC San Francisco used the gene editing technology CRISPR to turn ordinary white fat cells into “beige” fat cells, which voraciously consume calories to make heat. The work is funded by the National Institute of Health (NIH).

Then, they implanted them near tumors the way plastic surgeons inject fat from one part of the body to plump up another. The fat cells scarfed up all the nutrients, starving most of the tumor cells to death. The approach even worked when the fat cells were implanted in mice far from the sites of their tumors.

The approach's reliance on a common procedure could speed its use as a new form of cellular therapy.

“We already routinely remove fat cells with liposuction and put them back via plastic surgery,” said Nadav Ahituv, PhD, director of the UCSF Institute for Human Genetics and professor in the Department of Bioengineering and Therapeutic Sciences. He is the senior author of the paper, which appears Feb. 4 in Nature Biotechnology. “These fat cells can be easily manipulated in the lab and safely placed back into the body, making them an attractive platform for cellular therapy, including for cancer.”

Cold therapy sparks a new idea

Ahituv and his post-doc at the time, Hai Nguyen, PhD, were aware of studies that showed exposure to cold could suppress cancer in mice. One experiment even showed it could help a patient with non-Hodgkin lymphoma. Scientists concluded that the cancer cells were starving because the cold was activating brown fat cells.

But cold therapy isn’t a viable option for cancer patients with fragile health. So, Ahituv and Nguyen turned to the idea of using beige fat, wagering that they could engineer it to burn enough calories, even in the absence of cold, to deprive tumors of the fuel they needed to grow.

Nguyen, who is the first author of the paper, used CRISPR to activate genes that are dormant in white fat cells but are active in brown fat cells, in the hopes of finding the ones that would transform the white fat cells into the hungriest of beige fat cells.

A gene called UCP1 rose to the top. Nguyen grew UCP1 beige fat cells and cancer cells in a “trans-well” petri dish. The cancer cells were on the bottom and the fat cells were above them in separate compartments that kept the cells apart but forced them to share nutrients. The results were shocking.

“In our very first trans-well experiment, very few cancer cells survived. We thought we had messed something up – we were sure it was a mistake,” Ahituv recalled. “So, we repeated it multiple times, and we kept seeing the same effect.”

The beige fat cells held sway over two different types of breast cancer cells, as well as colon, pancreatic and prostate cancer cells.

No fat cells: Actively-multiplying cancer cells (pink) are seen in a mouse predisposed to develop breast cancer.  

Fat cells are added: When fat cells were implanted in the breast, far fewer cancer cells were able to multiply.  

Cancer is no match for hungry fat

But the researchers still didn’t know if the beige fat cells would work in a more realistic context. So, they turned to fat organoids, which are coherent clumps of cells grown in a dish, to see if they could beat tumor cells when they were implanted next to tumors in mice. The approach worked against breast cancer, as well as pancreatic and prostate cancer cells. The cancer cells starved as the fat cells gobbled up all the available nutrients.

Once implanted into mice that were genetically predisposed to develop cancer, the beige fat cells were so powerful that they suppressed pancreatic and breast tumors. Beige fat even worked when it was implanted far away from the breast cancer cells.

Fat cells grown in a petri dish. Image by Ahituv Lab

To see how the fat cells would work in human tissue, Ahituv and Nguyen teamed up with Jennifer Rosenbluth, MD, PhD, a breast cancer specialist at UCSF. Rosenbluth had amassed a library of breast cancer tissue from mastectomies containing both fat cells and cancer cells.

“Because the breast has a lot of fat, we could get fat from the same patient, modify the fat and grow it in a single trans-well experiment with that patient’s own breast cancer cells,” Ahituv said.

These same-patient beige fat cells outcompeted breast cancer cells in petri dishes – and when they were implanted together in mouse models.

Knowing that cancers have preferred diets, the researchers engineered fat just to eat certain nutrients. Certain forms of pancreatic cancer, for example, rely on uridine when glucose is scarce. So, they programmed the fat cells to eat just uridine, and they easily outcompeted the pancreatic cancer cells. This suggested that fat could be adapted to any cancer’s dietary preferences.

A new approach to living cell therapy

Fat cells have many advantages when it comes to living cell therapies, according to Ahituv. They are easy to obtain from patients. They grow well in the laboratory and can be engineered to express different genes and take on different biological roles. And they behave well once they are put back into the body, not straying from the location where they’re implanted and playing nice with the immune system.

It’s a conclusion supported by decades of plastic surgery.

“With fat cells, there’s less interaction with the environment, so there’s very little worry of the cells leaking out into the body, where they might cause problems,” Ahituv said.

Fat cells can also be programmed to emit signals or carry out more complicated tasks.

And their ability to defeat cancer even when they are not right next to tumors could prove invaluable for treating hard-to-reach cancers like glioblastoma, which affects the brain, as well as many other diseases.

“We think these cells could also be designed to sense glucose in the bloodstream and release insulin, for diabetes, or suck up iron in diseases where there’s excessive iron like hemochromatosis,” Ahituv said. “The sky’s the limit for these fat cells.”

Growing up in “404 Not Found”: China's nuclear city in the Gobi Desert

People in 404 Celebrating Chinese New Year

1. The City That Didn\u2019t Exist

In my childhood bedroom, a glossy map of China hung on the wall. I used to believe it showed our factory area, the 404. On that map, I saw Shanxi, where my father was from, and the Northeast, my mother\u2019s home. Our neighbors had roots in Shandong and Shanghai.

At age three, I would trace the map with my small finger, trying to find 404\u2019s Central Park or the Workers\u2019 Club. I couldn\u2019t find them. I assumed the large blue patch was my home, and the green patch belonged to my friend upstairs.

In reality, Factory 404 was not marked on any map.

Years later, when I first used the internet and saw \u201C404: Page Not Found\u201D pop up on a screen, I was genuinely perplexed. How did the computer know that \u201C404\u201D couldn\u2019t be found\uFF1F

Located west of the Yumen Pass, 404 was a secret society hidden in the Gobi Desert. In 1958, the state mobilized thousands to build this oasis for the radioactive industry. Conditions were brutal. Sandstorms were a daily reality. The early settlers dug holes in the ground and covered them with thatch just to survive the nights. To this day, the name of our railway station remains \u201CDi Wo Pu\u201D\u200A\u2014\u200Awhich literally means \u201CLow-Lying Hollow.\u201D

Water was scarce. With only 50 millimeters of annual rainfall, drilling for wells was futile. Initially, water had to be trucked in, costing as much as gasoline. There wasn\u2019t a single tree, only scattered camel grass. When construction workers took their children to the nearest town, Yumen, the kids would point at a real tree and scream, \u201CLook! Giant camel grass!\u201D

Even years later, the sandstorms persisted. Small stones were lifted by the wind and painfully hit our faces. Sometimes the sky turned tangerine color. When the storm finally settled, the ground was blanketed in a layer of dust. Every step kicked up a puff of fine powder.

The first generation of 404 were the country\u2019s brightest elites. We had locksmiths who could replicate a key just by glancing at it, and lathe operators who could diagnose a machine\u2019s fault with their eyes closed. It wasn\u2019t just engineers. There were top-notch chefs and pastry masters drawn from major cities. To this day, the taste of the cream pastries I ate as a child remains a vivid memory\u200A\u2014\u200Aa sweet luxury in the middle of a barren desert.

But the most crucial hands belonged to the machinists. At that time, sophisticated CNC machines didn\u2019t exist, yet the core components of an atomic bomb required a level of precision that bordered on the impossible. The final, most delicate cuts were executed by human hands manually guiding the machine tools, maintaining a margin of error within 1/80th the width of a human hair.

The legendary \u201Cfinishing touches\u201D were performed by Yuan Gongpu, a master lathe operator recruited from the Shanghai Automobile Chassis Factory. His story was typical of that generation: he had just gotten married in Shanghai in April, only to be whisked away to the desolate Northwest in August.

During the \u201CThree Years of Hardship\u201D (1959\u20131961), when more than 30 million people across China starved to death, our factory area faced a desperate crisis. At one point, there were only a few days\u2019 worth of rations left in the warehouses, and workers began to suffer from severe edema due to malnutrition.

Deep in the Northwestern hinterland, transportation was notoriously difficult, so the factory decided it had to survive on its own. They established a farm to grow their own grain and vegetables. They channeled melting snow and ice from the Qilian Mountains for water, and organized hunting teams to venture deep into the mountains to bring back meat.

Gradually, the factory area achieved self-sufficiency. As life improved, 404 grew into a fully functioning city. It built its own department stores and cinemas, and even established dedicated factories just to produce vinegar and popsicles. By the time I was born, this small enclave of fewer than 30,000 people even boasted its own zoo.

In my childhood, I used to spend time in the zoo

2.The Radioactive Sofa

The initial slogan proposed during the establishment of 404 was: \u201CDedicate your youth, dedicate your life, and dedicate your descendants.\u201D

I am that descendant\u200A\u2014\u200Athe third generation. I was born in 1991, thirty years after China\u2019s first atomic bomb explosion, and right around the time of the dissolution of the Soviet Union.

By then, the city\u2019s mission had shifted. With the bomb long finished, 404 had transformed into a massive processing center for nuclear waste. Spent fuel rods from nuclear power plants across the country were transported here, where they were submerged in deep cooling pools for reprocessing.

Despite its remote location in the desert, 404 held a strange political prestige. When the weather forecast aired on provincial TV, the capital, Lanzhou, was mentioned first. The second city was always the \u201CGansu Mining Area\u201D\u200A\u2014\u200Athe code name for 404.

Our license plates started with \u201CGan-A,\u201D the same as the provincial capital. We laughed at people from other cities like Jiayuguan (\u201CGan-B\u201D) or Jiuquan (\u201CGan-F\u201D). Even as kids, we joked, \u201CWe\u2019re still number one.\u201D Because our grandparents were the country\u2019s elite and we lived in the \u201CNuclear City,\u201D I always felt like I was living at the center of the world.

But there was a darker side to this status. Because of the radioactive materials, our residential area was separated from the factory by an hour-long train ride.

The most dangerous job was \u201Cworking in the pit.\u201D Shifts there were strictly limited to thirty minutes to minimize radiation exposure. Workers had to shower and change into protective gear immediately after their shifts. As kids, most of us had never seen the factory; our parents simply described it as \u201Cdirty.\u201D

Occasionally, we heard whispers about accidents\u200A\u2014\u200Ahair falling out overnight, or leaks caused by local farmers digging up buried chemical drums and protective gear. Once, a soldier entered the residential area after coming into contact with radioactive material. His hands turned a necrotic black, like charred wood. The authorities didn\u2019t just isolate him; they traced his entire trajectory and burned every single item he had touched. A friend of my father lost his entire sofa because of this. Witnessing such scorched-earth containment makes the modern definition of nuclear power as the \u2018cleanest energy\u2019 completely incomprehensible to me.

Our life in the residential area was anchored by the Workers\u2019 Club and the department store. The town was small\u200A\u2014\u200Aless than two kilometers from end to end\u200A\u2014\u200Aand bookended by parks: a fishpond in the north and a zoo in the south.

My home was in the north, near the tallest structure in town: the Communication Building. It was a seven-story tower topped with a massive four-sided clock. No matter where you stood in the factory area, you could see the time and hear its chimes ringing across the desert.

Both my parents worked nearby. Just south of my home, past the Communication Building, was the bank. A stone\u2019s throw east of that was my kindergarten.

When I was three and a half, my mother took me to Beijing for her studies. It was my first time leaving the desert. I remember jumping for joy inside the train carriage. When we reached Tiananmen Square, I was overwhelmed. I ran wild, waving a red inflatable toy hammer. I became a spectacle myself\u200A\u2014\u200Aa group of foreign tourists sat on the ground and pulled me over to take photos, unaware they were posing with a child from a secret nuclear city.

3. Pigs in Kindergarten

After returning from Beijing to 404, I was sent to the kindergarten.

The kindergarten was housed in a small, Western-style villa. While we sat inside the classroom, pigs roamed freely in the yard outside. Through the window, we could watch them rooting through the dirt. It was a perfect cycle: we ate the pigs, and the pigs ate our leftovers.

I couldn\u2019t stomach the fatty meat, so whenever the teacher wasn\u2019t looking, I would squeeze it in my hand and secretly stash it in my pocket. My mother only discovered this habit when she did the laundry. A few days later, when I visited the kindergarten teacher\u200A\u2014\u200Awho happened to be a former colleague of my mother\u200A\u2014\u200AI hid behind my mom\u2019s leg and confessed that I didn\u2019t like pork. The teacher smiled. The next day, the cafeteria served radish and vermicelli dumplings.

There was a formidable female teacher at the kindergarten. Unrequited love had driven her mad. Yet, strangely, we children weren\u2019t afraid of her. When she struck the ground with a long bamboo pole to demand silence, some kids would simply climb up the pole, giggling. The factory area was a sealed-off world; she wasn\u2019t the only one whose mind cracked under the strain of isolation and failed relationships. Later, her hair turned half-white and she grew heavy. She wandered the streets every day, yet the kindergarten continued to pay her salary.

My home life had its own rhythm: my father was often out playing mahjong at friends\u2019 houses, leaving my mother and me at home. While she was studying for a college exam, I played alone in my bedroom, weaving stories with my toys, emerging every hour just to ask her how the studying was going.

My biggest dream in kindergarten was to be a big brother. I wanted to care for a younger sibling. But under the One-Child Policy, if my mother had another child, she and my dad would lose their jobs. She had to follow the rules and terminate a pregnancy. My wish was impossible.

Whenever I felt unhappy, I would climb up to the second-floor terrace of the kindergarten, lift my shirt, and press my bare belly against the icy stone wall. I would whisper to myself, \u201CBig brother wants to go home.\u201D As the cold seeped into my skin, I would pull my shirt down, letting my body warmth return. This physical sensation\u200A\u2014\u200Afrom freezing to warm\u200A\u2014\u200Asomehow soothed my longing to be an older brother. But as a result, my digestion deteriorated, and my once-chubby figure withered into a skinny little bamboo stick.

My best friend lived upstairs. (We would eventually be neighbors for 13 years.)

Back in kindergarten, when she was in the Senior Group (the \u2018Big Class\u2019), I was still in the Middle Group. After lunch, I would spot her in the playroom across the hall and shout that I wanted to be in the Senior Group, too.

My mother pulled some strings with a former colleague, allowing me to move up a level early to join her. During nap time, our little beds were right next to each other. We would clutch candy wrappers in our hands, giggling endlessly. The teacher would scold us for disturbing the nap, but we Hid behind our parents, still laughing.

There was another boy in the neighboring unit, and the three of us often played under the acacia tree in front of our building. At four or five years old, I was deeply troubled by a serious question: which of us would eventually marry her?

After all the pigs in the backyard were consumed, I graduated from kindergarten and entered elementary school.

My elementary school was right next to the kindergarten. In front of the gates stood raised square concrete blocks\u200A\u2014\u200Aentrances to the air-raid shelters. In our factory town, these entrances were everywhere: at schools, residential buildings, and hospitals. To survive air raids and nuclear strikes, the underground of 404 was a labyrinth of interconnected tunnels. My parents told me that during the Sino-Soviet conflict in 1969, the Soviet Union had threatened to attack China\u2019s nuclear facilities. Back then, alarms rang frequently, sending teachers and students rushing underground.

By the time I entered school, the shelters had long been abandoned, serving only as a playground. I once tried to use an umbrella to parachute off one of the concrete blocks and ended up spraining my ankle.

It was the season when residents hung Chinese cabbage outside to dry for winter. My classmates invented a game of rock-paper-scissors nearby. The rule was simple: the loser had to grab a cabbage and throw it down into the air-raid shelter. They played all afternoon. By sunset, not a single cabbage was left in front of the building.

\\\"\\\"

The abandoned primary school and the entrance to the air-raid shelter

School started at 8:30, but I would often arrive at 6:30, all by myself. I went that early precisely because no one else was there; in that solitude, I felt a quiet sense of freedom. Once, I misread the clock and arrived at 5:00 AM, only to find a little girl from the neighboring class already there. We stood at the school gate with nothing to do, so she started telling ghost stories. She told me about a room next to the slide that was locked year-round, where someone had seen a pair of bloody eyes peering out. As she spoke, she clutched her own neck and stared at me with such a sharp, intense look that I almost cried.

\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014\u2014

This was the golden age of 404\u2014a utopian bubble built on hollow ground. But bubbles, no matter how beautiful, eventually burst.

In Part 2 next week: The darkness creeps in. We\u2019ll talk about the executions in the \u201CBack Mountain,\u201D the animals in the zoo going mad, and the day the entire city began to migrate into the unknown.

C++ says “We have try. . . finally at home”

devblogs.microsoft.com - Comments

Many languages¹ that have exceptions also have a finally clause, so you can write

try {
    ⟦ stuff ⟧
} finally {
    always();
}

A quick checks shows that this control structure exists in Java, C#, Python, JavaScript, but not C++.

C++ says, “We have try…finally at home.”

In C++, the way to get a block of code to execute when control leaves a block is to put it in a destructor, because destructors run when control leaves a block. This is the trick used by the Windows Implementation Library’s wil::scope_exit function: The lambda you provide is placed inside a custom object whose destructor runs the lambda.

auto ensure_cleanup = wil::scope_exit([&] { always(); });

⟦ stuff ⟧

Although the principle is the same, there are some quirks in how each language treats the case where the finally or destructor itself throws an exception.

If control leaves the guarded block without an exception, then any uncaught exception that occurs in the finally block or the destructor is thrown from the try block. All the languages seem to agree on this.

If control leaves the guarded block with an exception, and the finally block or destructor also throws an exception, then the behavior varies by language.

  • In Java, Python, JavaScript, and C# an exception thrown from a finally block overwrites the original exception, and the original exception is lost. Update: Adam Rosenfield points out that Python 3.2 now saves the original exception as the context of the new exception, but it is still the new exception that is thrown.
  • In C++, an exception thrown from a destructor triggers automatic program termination if the destructor is running due to an exception.²

So C++ gives you the ability to run code when control leaves a scope, but your code had better not allow an exception to escape if you know what’s good for you.

¹ The Microsoft compiler also supports the __try and __finally keywords for structured exception handling. These are, however, intended for C code. Don’t use them in C++ code because they interact with C++ exceptions in sometimes-confusing ways.

² This is why wil::scope_exit documents that it will terminate the process if the lambda throws an exception. There is an alternate function wil::scope_exit_log that logs and then ignores exceptions that are thrown from the lambda. There is no variation that gives you Java-like behavior.

Fathers’ choices may be packaged and passed down in sperm RNA

www.quantamagazine.org - Comments

In March 2025, in a preprint uploaded to biorxiv.org, Mansuy and colleagues reported that EVs in mice can transport certain RNAs, metabolites and lipids linked to early-life stress from circulating blood to sperm, with consequences for offspring. The offspring produced by these sperm cells had stress-related metabolic dysfunction as adults and bore the stress signatures in their own sperm RNA. “These changes imply a mechanistic link between sperm RNA modifications and phenotypic features in the offspring,” Mansuy’s team concluded in their paper, which has not yet been peer-reviewed.

Phenotypic Translation

Perhaps the trickiest step to understand is how sperm-borne molecules could influence an adult’s observable traits. In one form of experiment, researchers extract all the sperm RNA from mice that have been raised under stressful or health-altering conditions. Those isolated RNAs are then injected into a zygote. Pups that emerge usually “get the dad’s phenotypes,” Conine said, suggesting that the RNAs alone confer traits from dad to offspring.

But how? During early development, epigenetic processes reign. As one fertilized cell divides into two, and those cells divide again, and so on, one set of DNA instructions is dynamically and repeatedly reprogrammed. The growing body specializes into different cell types and is sculpted into a sequence of increasingly complex forms. It’s possible, then, that early epigenetic alterations to the genome could have significant downstream effects on an adult.

Portrait of Dr. Xin Yin (top) and Dr. Xi Chen (bottom)

A team of researchers, including Xin Jin (top) and Xi Chen of Nanjing University, traced the epigenetic effects of paternal exercise in mice.

Research out of Conine’s lab, published in 2024, showed that sperm microRNAs alter gene expression in mouse embryos. Experiments like these, he said, support the idea that offspring can inherit paternal traits via the transfer of non-DNA molecular stowaways in sperm.

The recent Cell Metabolism paper took this idea a step further by tracing a mechanism by which this can happen. A team of more than two dozen Chinese researchers focused on the epigenetic transmission of exercise benefits, homing in on a set of microRNAs that reprogram gene expression in the early embryo. These changes ultimately result in skeletal muscle adaptations in adult offspring that enhance exercise endurance. The researchers found that well-exercised mice had more of these microRNAs in their sperm than sedentary mice did. When these microRNAs were transferred into zygotes, the adults they grew into were more physically fit, with more mitochondria in skeletal muscle and higher endurance.

But how did the molecules generate the exercise-positive phenotype? In experiments, the researchers found that the microRNAs suppressed a particular protein, which had the effect of boosting genes related to mitochondrial activity and metabolism.

Intriguingly, the sperm of physically trained male humans also hosted higher levels of many of the same microRNAs than those of untrained cohorts. “This cross-species conservation suggests a potential role for these sperm mi[cro]RNAs in intergenerational exercise adaptations in humans,” the researchers wrote.

The First Draft

The notion that a father’s lived experience can become recorded by his body, transmitted to his gametes and relayed to his offspring is no longer as outlandish as it once seemed. Many researchers in the field are willing to float speculative visions of what could be going on, even as they acknowledge that gaps remain.

“Our hypothesis is that the epididymis ‘sees’ the world and alters the small RNAs it produces in response,” Rando said. “These RNAs are then delivered to the zygote upon fertilization and control early gene regulation and development to shape offspring health and disease.”

Conine speculates that once certain RNAs make their way into the egg, they trigger “a cascade of changes in developmental gene expression that then leads to these phenotypes” of the father showing up in the next generation. Remarkably, this unfolds even though the sheer volume of the sperm’s contents is so much less than an egg’s contents, including the relative amounts of RNA.

The full picture of how paternal experience and behavior might epigenetically influence offspring is not nearly in hand. Researchers are currently piecing the story together, one experiment at a time, rather than proving out every step sequentially in the same set of organisms. One of the gaps is in the characterization of what RNA and perhaps other epigenetic factors do in the zygote to modify genomic activity as it unfolds during development, Mansuy said.

“We are still blind men describing for the first time different parts of the same elephant,” Chen said. “The underlying mechanism is almost certainly an orchestra of a sperm RNA code and factors beyond that.”

Confirming the findings in humans would take enormous effort, but it would be key to turning these findings in mice into “informed medical advice,” Chen said. This would require well-controlled experiments following multiple generations, tracking diet, exercise, aging and environmental exposures, while also using advanced tools to decode sperm-packaged molecules — and then looking for strong correlations between the molecular and phenotypic data.

Even amid the uncertainties, researchers are cautiously moving forward as they learn to believe the results of their own experiments. If they’re right, they will have discovered a new fact of life, Rando said. When he thinks about his two boys, he wonders what he might have done differently when he was younger, before they were born, that might have tweaked his RNA profile in ways that would affect them today.

“We don’t know enough yet to develop guidance like that,” Rando said. “Maybe we will get there.”

Replacing JavaScript with Just HTML

www.htmhell.dev - Comments

by Aaron T. Grogg published on Dec 27, 2025

For many years now, JavaScript has been the workhorse of the web. If you wanted to do something that couldn't be done with just HTML and CSS, you could usually find a way to do it with JS.
And that is great! JS has helped push user experiences forward, and honestly helped push HTML and CSS forward!

But as time marches on, and the HTML and CSS methods gain traction, we need to start replacing the old JS methods that feel so comfy with new methods that require less JS.

Nothing against JS, but it has better things to do than setup and manage your accordions or offscreen navigation menus... Plus, JS needs to be downloaded, decompressed, evaluated, processed, and then often consumes memory to monitor and maintain features. If we can hand-off any JS functionality to native HTML or CSS, then users can download less stuff, and the remaining JS can pay attention to more important tasks that HTML and CSS can't handle (yet).

Below are a few examples; any you care to add?

Table of Contents:

Accordions / Expanding Content Panels

Description:

The details and summary HTML elements provide an HTML-only replacement to the typical JS accordion:
Examples of HTML  element expanding and contracting
CopePen: Accordion / Expanding Content

Use cases:

  • Hiding/showing content
  • Expanding content sections

Basic implementation:

<details>
<summary>Initially closed, click to open</summary>
Content is initially hidden, but can be revealed by clicking the summary.
</details>

Add an open attribute to set the default appearance as "open":

<details open>
<summary>Initially open, click to close</summary>
Content is initially visible, but can be hidden by clicking the summary.
</details>

Use the same name attribute on all related details (like radio buttons) to restrict only one open panel at a time:

<details name="foo" open>
<summary>Initially open, clicking others will close this</summary>
Content is initially visible, but can be hidden by clicking the summary; only one panel can be open at a time.
</details>
<details name="foo">
<summary>Initially closed, clicking will open this, and close others</summary>
Content is initially hidden, but can be revealed by clicking the summary; only one panel can be open at a time.
</details>
<details name="foo">
<summary>Initially closed, clicking will open this, and close others</summary>
Content is initially hidden, but can be revealed by clicking the summary; only one panel can be open at a time.
</details>

You can also customize the appearance with CSS and trigger the open/close via JS.

Learn more about the details element in the previously-published “For the Love of <details>".

Input with Autofilter Suggestions Dropdown

Description:

Combining the HTML input and datalist elements can create a dropdown of options that autofilters as you type:
Examples of HTML  and  providing autofilter dropdown
CodePen: Input with Autofilter Suggestions Dropdown

Use cases:

  • Site search
  • Product search or filter
  • Filter any list of data

Basic implementation:

<label for="browser">Browser</label>
<input type="text"
list="browsers"
id="browser" name="browser"
size="50"
autocomplete="off" />

<datalist id="browsers">
<option value="Arc"></option>

<option value="Microsoft Edge"></option>
<option value="Opera"></option>
<option value="Safari"></option>
<option value="Tor"></option>
<option value="Vivaldi"></option></option>
</datalist>

You can also use other input types:

<label for="quantity">Quantity</label>
<input type="number"
list="quantity-options"
id="quantity" name="quantity" />

<datalist id="quantity-options">
<option value="1"></option>
<option value="2"></option>
<option value="5"></option>
<option value="10"></option>
<option value="20"></option>
<option value="50"></option>
</datalist>

<label for="appointment">Appointment</label>
<input type="time"
list="appointments"
id="appointment" name="appointment" />

<datalist id="appointments">
<option value="12:00"></option>
<option value="13:00"></option>
<option value="14:00"></option>
</datalist>

Note that, at the time of this writing, Firefox was limited to only textual-based input types, so no date, time, range or color for now... :-(

Also note that, at the time of this writing, there are limitations on mobile, and accessibility concerns.

Modals / Popovers

Description:

The popover and popovertarget attributes can replace the traditional JS-driven modal/popover/overlay:
Examples of HTML  elements opening and closing
CodePen: Modal / Popover

Use cases:

  • Hiding/showing side panels / additional information

Basic implementation

An auto popover (default) can be "light dismissed" (clicking outside of it or hitting the esc key). Opening an auto automatically closes any other auto popovers that were open. Clicking the button a second time will close the one it opened.

<button popovertarget="pop-auto">
Toggle Popover
</button>
<dialog popover id="pop-auto">
I'm an "auto" Popover!
</dialog>

A hint popover can also be "light dismissed". It does not close other hint popovers when opened. Clicking the button a second time will close the one it opened.

<button popovertarget="pop-hint">
Toggle Popover
</button>
<dialog popover="hint" id="pop-hint">
I'm a "hint" Popover!
</dialog>

Note that, at the time of this writing, Firefox and all iOS varieties do not support hint popovers.

A manual popover can not be "light dismissed". It does not close other manual popovers when opened. Clicking the button a second time will close the one it opened.

<button popovertarget="pop-manual">
Toggle Popover
</button>
<dialog popover="manual" id="pop-manual">
I'm a "manual" Popover!
</dialog>

Learn more about the opening and closing dialogs and popovers in the previously-published “Controlling dialogs and popovers with the Invoker Commands API".

Browser compatibility:

Offscreen Nav / Content

Description:

The above Modal / Popover functionality can also be used to create an offscreen navigation that requires no JS:
Example of HTML Popover used as an offscreen navigation menu

CodePen: Offscreen Content

Use cases:

  • Hiding/showing navigation menus

Basic implementation:

<button popovertarget="menu">
Toggle Menu
</button>
<nav popover id="menu">
Nav Content
</nav>
#menu {
margin: 0;
height: 100vh;
translate: -100vw;
}
#menu:popover-open {
translate: 0;
}

I use a nav element to give it semantic value, but you can use any HTML element (div, section, aside, etc.).

A popover defaults to position: fixed per the User Agent Stylesheet, and is simply pushed off screen when closed, and pulled back onscreen when it is open. Note that margin: 0 is required if you want to override the User Agent center-alignment.

Clicking outside of the above menu closes it. You can force the panel to stay open, requiring a manual/explicit close, by using popover="manual".

You can also add a backdrop pseudo element and style it as you wish:

#menu::backdrop {
background: rgb(190 190 190 / 75%);
}

Conclusion

While we all love the power and flexibility JS provides, we should also respect it, and our users, by limiting its use to what it needs to do.

There is so much more that has changed in recent years, including a ton of options that CSS now covers. If you are now hungry for more, have a look at [my longer article that covers those as well](https://aarontgrogg.com/blog/2023/05/31/replace-js-with-no-js-or-lo-js-options/.

Happy reducing!

Functional programming and reliability: ADTs, safety, critical infrastructure

blog.rastrian.dev - Comments

In banking, telecom, and payments, reliability is not a nice to have. It is table stakes. The most reliable systems I have worked on reduce entire classes of bugs before the code even runs. Functional programming and Algebraic Data Types (ADTs) let you push correctness into the type system, so illegal states cannot be constructed in the first place.

What you will learn

  • How invalid states show up in real systems and why they cause costly incidents
  • How ADTs encode business rules so the compiler enforces them
  • How pattern matching and exhaustiveness checks turn refactors into safe edits
  • Practical modeling patterns for banking and telecom domains in TypeScript and OCaml
  • A migration playbook that juniors and mid-levels can apply today

References


1) Reliability starts at the type system

Most production incidents are not due to complex algorithms. They are due to the code entering a state that should never have been possible. If you have been on call, you have seen variants of these:

  • Magic strings: "paypal" sneaks into a system that only supports Cash, Card, Pix
  • Nulls: a function expects an email and receives null in a path you forgot to guard
  • Conflicting booleans: an account is both isActive = true and isSuspended = true
  • Incomplete lifecycles: a transaction is marked Pending and then jumps to Reversed without an associated Settled record

Functional programming helps by modeling the domain with types that make invalid states unrepresentable. Pure functions and immutability keep behavior predictable and testable.

Examples of invalid state patterns and their type-safe replacements


2) ADTs in practice: sums and products

Product types combine fields, think "and". Sum types choose one of several cases, think "or". Together they model your domain rules.

Product type example

(* OCaml *)
type user = {
  id    : int;
  name  : string;
  email : string option;  (* Some "[email protected]" or None *)
}
// TypeScript
type User = Readonly<{
  id: number;
  name: string;
  email?: string; // we will improve this with Option next
}>;

Sum type example

(* OCaml *)
type payment =
  | Cash
  | Card of string   (* last 4 digits *)
  | Pix  of string
// TypeScript discriminated union
type Payment =
  | { kind: "cash" }
  | { kind: "card"; last4: string }
  | { kind: "pix"; key: string };

With this shape, "paypal" cannot exist as a Payment. The compiler refuses the value.

Product types combine fields; sum types choose one of several variants


3) Pattern matching and exhaustiveness

When you pattern match on a sum type, the compiler can force you to handle every variant. If you later add a new case, every non exhaustive match becomes a compilation error or warning. This is how refactors become safe by default.

(* OCaml *)
let describe_payment = function
  | Cash -> "Paid in cash"
  | Card last4 -> "Card ••••" ^ last4
  | Pix key -> "Pix " ^ key
// TypeScript
const assertNever = (x: never): never => { throw new Error(`Unhandled variant: ${JSON.stringify(x)}`) }

function describePayment(p: Payment): string {
  switch (p.kind) {
    case "cash":  return "Paid in cash"
    case "card":  return `Card ••••${p.last4}`
    case "pix":   return `Pix ${p.key}`
    default:      return assertNever(p)
  }
}

Add a new Crypto method and both code bases will point out every place you must update.


4) Failure scenarios and their type driven fixes

4.1 Banking example: double settlement and reconciliation drift

Incident story
A payout worker retries on network timeouts and calls settle() twice. The table allows pending = false and settled = true twice with the same ledger id. Reconciliation finds duplicates and accounting needs a manual fix.

Why it happened
State is spread across booleans and strings. The database does not express the lifecycle. The application code does, but only by convention and tests.

Allowed transitions for a transaction from Pending to Settled, Failed, or Reversed.

Fix with ADTs

(* OCaml *)
type failure_reason =
  | InsufficientFunds
  | ComplianceHold
  | NetworkError of string

type txn_state =
  | Pending
  | Settled  of string       (* ledger_id *)
  | Failed   of failure_reason
  | Reversed of string       (* original_ledger_id *)

type txn = {
  id           : string;
  amount_cents : int;
  state        : txn_state;
}
// TypeScript
type FailureReason =
  | { kind: "insufficientFunds" }
  | { kind: "complianceHold" }
  | { kind: "networkError"; message: string }

type TxnState =
  | { kind: "pending" }
  | { kind: "settled"; ledgerId: string }
  | { kind: "failed"; reason: FailureReason }
  | { kind: "reversed"; originalLedgerId: string }

type Txn = Readonly<{
  id: string
  amountCents: number
  state: TxnState
}>

Transitions become total functions. You can return a Result when a transition is not allowed.

(* OCaml *)
type 'a result = Ok of 'a | Error of string

let settle (t: txn) (ledger_id: string) : txn result =
  match t.state with
  | Pending -> Ok { t with state = Settled ledger_id }
  | Settled _ -> Error "already settled"
  | Failed _ -> Error "cannot settle a failed transaction"
  | Reversed _ -> Error "cannot settle a reversed transaction"
// TypeScript
type Ok<T>  = { _tag: "Ok"; value: T }
type Err<E> = { _tag: "Err"; error: E }
type Result<T, E> = Ok<T> | Err<E>
const Ok = <T>(value: T): Result<T, never> => ({ _tag: "Ok", value })
const Err = <E>(error: E): Result<never, E> => ({ _tag: "Err", error })

function settle(t: Txn, ledgerId: string): Result<Txn, string> {
  switch (t.state.kind) {
    case "pending":  return Ok({ ...t, state: { kind: "settled", ledgerId } })
    case "settled":  return Err("already settled")
    case "failed":   return Err("cannot settle a failed transaction")
    case "reversed": return Err("cannot settle a reversed transaction")
  }
}

Now the illegal transitions are blocked by construction. Test coverage still matters, but the shape of the model prevents a class of bugs.

Refactor safety
When product adds Chargeback, the compiler highlights every match that ignores it. You cannot ship with a half handled lifecycle.

type TxnState =
  | { kind: "pending" }
  | { kind: "settled"; ledgerId: string }
  | { kind: "failed"; reason: FailureReason }
  | { kind: "reversed"; originalLedgerId: string }
  | { kind: "chargeback"; networkRef: string } // new

Every switch on TxnState now requires a chargeback branch. This is free guidance from the compiler.


4.2 Telecom example: ghost billing and incomplete sessions

Incident story
The call detail record pipeline generates billing events whenever it sees a Connected event. Under jitter and retries, some sessions never receive Completed. The billing system charges based on the wrong boundary and customers complain.

Why it happened
The call lifecycle is implicit across many services. A connected session with no end was still billable because there was no type that separated non billable states from billable ones.

Call session lifecycle; only Completed produces a billable duration

Fix with ADTs

(* OCaml *)
type drop_reason = Network | Busy | Timeout

type call =
  | Dialing   of int                   (* at_ms *)
  | Connected of int                   (* started_ms *)
  | Dropped   of drop_reason * int     (* reason, at_ms *)
  | Completed of int * int             (* started_ms, ended_ms *)

let billable_seconds = function
  | Completed (start_ms, end_ms) -> max 0 (end_ms - start_ms) / 1000
  | _ -> 0
// TypeScript
type DropReason = "network" | "busy" | "timeout"

type Call =
  | { kind: "dialing";   atMs: number }
  | { kind: "connected"; startedMs: number }
  | { kind: "dropped";   reason: DropReason; atMs: number }
  | { kind: "completed"; startedMs: number; endedMs: number }

const billableSeconds = (c: Call): number => {
  switch (c.kind) {
    case "completed": return Math.max(0, (c.endedMs - c.startedMs) / 1000)
    default:          return 0
  }
}

Now a connected but never completed call cannot produce a billable duration. The shape forbids the bug.


4.3 Config parsing example: hidden NaN and partial failures

Incident story
A cache TTL is stored in an environment variable. Someone sets CACHE_TTL_SECS=30s. In JavaScript, Number("30s") yields NaN and your code treats it as zero, disabling caching in production.

Fix with Result types

(* OCaml *)
type 'a result = Ok of 'a | Error of string

let parse_int (s: string) : int result =
  try Ok (int_of_string s) with _ -> Error "invalid int"

let load_ttl () : int option =
  match Sys.getenv_opt "CACHE_TTL_SECS" with
  | None -> None
  | Some s ->
    match parse_int s with
    | Ok n -> Some n
    | Error _ -> None  (* or propagate the error *)
// TypeScript
const parseIntR = (s: string): Result<number, "invalid-int"> =>
  /^-?\d+$/.test(s) ? Ok(Number(s)) : Err("invalid-int")

function loadTtl(): Option<number> {
  const raw = process.env.CACHE_TTL_SECS
  if (!raw) return None
  const parsed = parseIntR(raw)
  return parsed._tag === "Ok" ? Some(parsed.value) : None
}

The ambiguity disappears. The code must handle absence and parse errors explicitly.


5) Options and Results as first class tools

Do not use null to mean "maybe". Do not throw exceptions for expected errors.

Control flow using Option and Result instead of nulls or thrown errors

Option or Maybe

(* OCaml *)
type user = { id: int; email: string option }

let send_mail (u: user) =
  match u.email with
  | Some e -> (* send e *) ()
  | None   -> ()
// TypeScript
type None = { _tag: "None" }
type Some<T> = { _tag: "Some"; value: T }
type Option<T> = None | Some<T>
const None: None = { _tag: "None" }
const Some = <T>(value: T): Option<T> => ({ _tag: "Some", value })

const map = <A, B>(o: Option<A>, f: (a: A) => B): Option<B> =>
  o._tag === "Some" ? Some(f(o.value)) : None

Result or Either

(* OCaml *)
let result_map f = function
  | Ok x -> Ok (f x)
  | Error e -> Error e
// TypeScript
type Ok<T>  = { _tag: "Ok"; value: T }
type Err<E> = { _tag: "Err"; error: E }
type Result<T, E> = Ok<T> | Err<E>
const Ok  = <T>(value: T): Result<T, never> => ({ _tag: "Ok", value })
const Err = <E>(error: E): Result<never, E> => ({ _tag: "Err", error })

These types make the happy path and the error path equally explicit.


6) Immutability and why it simplifies reasoning

Mutable shared state is a common source of heisenbugs under concurrency. Prefer immutable data and pure functions. When you need to update, create a new value.

(* OCaml *)
let set_email (u: user) (e: string option) : user =
  { u with email = e }
// TypeScript
type User = Readonly<{ id: number; name: string; email: Option<string> }>

const setEmail = (u: User, email: Option<string>): User =>
  ({ ...u, email })

Your tests become simple. Given the same inputs, the function returns the same output.


7) Smart constructors and newtypes to protect units and invariants

Numbers are not self describing. Create types that carry meaning.

Branded types prevent mixing incompatible numeric units

(* OCaml *)
module Cents : sig
  type t
  val make : int -> t            (* reject negatives *)
  val add  : t -> t -> t
end = struct
  type t = Cents of int
  let make x = if x < 0 then invalid_arg "negative cents" else Cents x
  let add (Cents a) (Cents b) = Cents (a + b)
end
// TypeScript
type Brand<K, T> = K & { __brand: T }

type Cents = Brand<number, "Cents">
const Cents = (n: number): Cents => {
  if (!Number.isInteger(n) || n < 0) throw new Error("invalid cents")
  return n as Cents
}

type Millis = Brand<number, "Millis">
const Millis = (n: number): Millis => n as Millis

const price: Cents = Cents(500)
// const wrong: Cents = Millis(500)  // type error

You stop mixing milliseconds with seconds or dollars with cents by accident.


8) Pure core, effectful shell

Keep the domain logic pure and push IO to the edges. This makes unit tests cheap and fast.

(* OCaml, pure core *)
let authorize_payment (amount: Cents.t) (balance: Cents.t) : bool =
  amount <= balance  (* assume a comparison helper inside the module *)

(* impure shell *)
let run () =
  let amount = Cents.make 500 in
  let balance = Cents.make 1200 in
  if authorize_payment amount balance then
    (* call database and payment gateway here *) ()
// TypeScript, pure core
const authorizePayment = (amount: Cents, balance: Cents): boolean => {
  return (amount as unknown as number) <= (balance as unknown as number)
}

// effectful shell
async function run() {
  const amount = Cents(500)
  const balance = Cents(1200)
  if (authorizePayment(amount, balance)) {
    // perform DB writes or API calls here
  }
}

9) Migration playbook

Start small and make continuous progress. Here is a practical order for a team new to these ideas.

  1. Replace pairs of booleans with a sum type

    • Before: { isActive: boolean; isSuspended: boolean }
    • After: type AccountState = { kind: "active" } | { kind: "suspended" } | { kind: "closed" }
  2. Replace string enums with discriminated unions

    • Avoid free form strings like "pending" | "settled" | "failed" | string
  3. Replace nullable fields with Option

    • OCaml string option
    • TypeScript Option<string> or a stricter domain specific union
  4. Replace thrown control flow with Result

    • Reserve exceptions for truly unexpected situations
  5. Introduce newtypes or branded types for units and ids

    • Prevent mixing Millis with Seconds, Cents with Dollars
  6. Enforce exhaustiveness

    • OCaml already warns
    • TypeScript: discriminated unions, assertNever, strictNullChecks, noImplicitReturns
  7. Add guard rails in CI

    • Treat TypeScript non exhaustive switches and OCaml warnings as errors

Smells to look for

  • Multiple booleans that can be true at the same time
  • Strings that travel far before being validated
  • Functions that sometimes return a value and sometimes throw
  • Types that carry numbers without units

10) Performance and ergonomics

Pattern matching compiles to simple branches. Discriminated unions in TypeScript are just plain objects. The main cost you will feel is validation at the boundaries in smart constructors. This is a trade worth making. The compiler then protects the interior of the system.


Conclusion

Reliability is designed. With Algebraic Data Types, pattern matching, Option and Result, immutability, and smart constructors, you encode domain rules directly in your types. Illegal states cannot compile. This is why industries that cannot afford failure, such as banking and telecom, gravitate to functional ideas.

If you work on code that touches money, minutes, or public availability, adopt these patterns now.

  • Model workflows with sum types, not conflicting flags
  • Use Option and Result instead of nullable and throwable APIs
  • Keep a pure core with effects at the edges
  • Brand units and identifiers
  • Enforce exhaustiveness during code review and in CI

Your on call shifts will be quieter, and your users will notice the difference.

Public Domain Day 2026

Montage of 1929 Works

January 1, 2026 is Public Domain Day: Works from 1930 are open to all, as are sound recordings from 1925!

By Jennifer Jenkins and James Boyle[1]
CC BY 4.0
Please note that this site is only about US law; the copyright terms in other countries are different.[2]

On January 1, 2026, thousands of copyrighted works from 1930 enter the US public domain, along with sound recordings from 1925. They will be free for all to copy, share, and build upon.[3] The literary highlights range from William Faulkner’s As I Lay Dying to Agatha Christie’s The Murder at the Vicarage and the first four Nancy Drew novels. From cartoons and comic strips, the characters Betty Boop, Pluto (originally named Rover), and Blondie and Dagwood made their first appearances. Films from the year featured Marlene Dietrich, Greta Garbo, the Marx Brothers, and John Wayne in his first leading role. Among the public domain compositions are I Got Rhythm, Georgia on My Mind, and Dream a Little Dream of Me. We are also celebrating paintings from Piet Mondrian and Paul Klee. Below you can find lists of some of the most notable books, characters, comics, and cartoons, films, songs, sound recordings, and art entering the public domain.[4] After each of them, we have provided an analysis of their significance. At the end of the article, we explain:

Conclusion

BOOKS

This is just a small selection from the thousands of books and plays entering the public domain in 2026. The famous works include modernist masterpieces, detective stories, a science-fiction classic, an early self-help book, and a seminal work on psychoanalysis. All of them and thousands more will be copyright-free in the US. The newly public domain corpus also includes a wealth of children’s and young adult fiction—the first four Nancy Drew books, the introduction of the characters Dick and Jane, a Newbery Award winner about the life of The Buddha, and the popular illustrated version of The Little Engine That Could.

Works from 1930 are not only enriching the public domain; they also illustrate its value.

“I have an idea that the only thing which makes it possible to regard this world we live in without disgust is the beauty which now and then men create out of the chaos. The pictures they paint, the music they compose, the books they write, and the lives they lead. Of all these the richest in beauty is the beautiful life. That is the perfect work of art.” –W. Somerset Maugham

That is a quote from W. Somerset Maugham, whose novel Cakes and Ale is entering the public domain in 2026. But artists don’t merely create “beauty…out of the chaos,” though our current moment has lots of the latter. They create beauty by drawing on our shared culture. Look at Maugham’s title: “Cakes and Ale.” Maugham himself was referring to a classic public domain work, in this case Shakespeare’s Twelfth Night. “Dost thou think, because thou art virtuous, there shall be no more cakes and ale?” says Sir Toby Belch reprovingly to his pompous Puritan steward Malvolio, who is always eager to judge the behavior of others. Maugham reuses the line precisely to make the same point about puritanical moralizing and, in the case of his novel, artistic hypocrisy. The narrator is disgusted by the snobbery and judgmental attitudes of his contemporaries towards Rosie Driffield, a former barmaid who became the wife of a famous fictional novelist. Rosie came from a working-class background and was forthright, without pretension, and sexually free. She is now decried for those qualities, but the narrator finds her far more impressive than the bourgeois scolds who disdain her. The title reaches back 330 years to show that one of our greatest playwrights was mocking faux puritanism in exactly the same way. Maugham's point is that the human race relives those moments and emotions in every era; the desire to moralize is always with us. Now his work is in the public domain and we, too, can reuse his insights and artistry to create new art.

The same point holds true for many of the other works entering the public domain this year. The title of Faulkner’s As I Lay Dying came from Homer’s Odyssey. The public domain contains far more than works with expired copyrights—names, titles, and very short phrases are not copyrightable standing alone and are therefore public domain in the US; one does not have to wait for the expiration of the copyright term. But when works enter the public domain, the artistic freedom granted over them is far greater. Plot, characters, images, vignettes; all can now be mined for future inspiration. And that, too, was true in the past just as it is now. The tale of the tenacious little engine that pulls the train over the mountain had been circulating in various forms before the Watty Piper version, or the predecessor it credits.[5] To tell new stories, we draw from older ones. One work of art inspires another – that is how the public domain feeds creativity. Why care about the public domain? That is one reason why.

CHARACTERS, COMICS, CARTOONS


Betty Boop was introduced in the Fleischer Studios’ wonderful cartoon Dizzy Dishes, set in a restaurant full of anthropomorphic animals. She is instantly recognizable, with the familiar flapper girl appearance, pouting lips, enormous doe eyes, tiny button nose, and kiss-curls. She even sings her high-pitched “Boop Oop A Doop” tagline—but in a characteristic Fleischer touch of surrealism she has elongated dog ears (similar in shape to her later hoop earrings) and facial expressions that morph between human and animalistic. Betty’s boyfriend-to-be is a dog-chef called Bimbo, who serenades her on a duck that transforms into a guitar, while the restaurant clientele and staff include a fantastical menagerie of animals. The vibe is decidedly trippy: duck-guitars, lovestruck dog-chefs, dancing flapper cats, and needy gorillas. Betty is remarkably sexy. But, because she was designed as a girlfriend for Bimbo, she also has dog ears. The dissonance fits the setting. By contrast, Disney’s character Rover, later renamed Pluto, inhabits a world in The Picnic that is both cuter and more normal—Rover licks Mickey with unbridled enthusiasm, chases rabbits, and provides Mickey and Minnie with comedic canine companionship. 

The contrast between the Fleischer and Disney aesthetics is fascinating. Max Fleischer once said, “If it can be done in real life, it isn’t animation.” Dizzy Dishes certainly does not disappoint. As described by the late Charles Silver, who ran MoMA’s Film Study Center, “Disney was based in Los Angeles and reflected the ‘wholesome’ mid-American values of Uncle Walt’s Kansas City roots. Fleischer’s New York product was more sophisticated and cosmopolitan…Broadly speaking, there was an innocence in Disney’s view of the world, while Fleischer projected an underlying kinkiness.” Our colleague Casey Herbert, who teaches cartoon history at Duke, put it this way: “Max and Dave Fleischer’s characters were drawn from the urban environment they knew so well. Vaudeville, dance-halls, diners, drinking and drugs were routinely part of the hallucinogenic mayhem…On the other hand, Walt, his brother Roy, and best friend Ub Iwerks, the core of the early Disney enterprises, all had roots in rural middle America. With upbeat music and clever solutions, mechanical and animal troubles of all sorts were resolved with a simple, can-do attitude that Mickey and his pals exude.”

As more of Disney’s and Fleischer’s classic works enter the public domain, it is worth reflecting on how deeply their styles are embedded in the DNA of today’s animation. Now, entering 2026, we look back and think it inevitable that one genre of cartoons will be cutesy and folksy, with slapstick humor and an upbeat vibe, while another will use the unparalleled artistic freedom afforded by the cartoon medium to explore a distinctly more surreal worldview, sensual and trippy, with wild nightlife and mind-bending transformations. Looking back to 1930, we can find the progenitors of both, and see how the traditions began to diverge. Indeed, it is striking how “edgily modern” some of the Fleischer cartoons feel. To look into each year’s newly public domain crop is to open a time-capsule that offers fresh insights about our culture.

As with Mickey Mouse, Popeye, and Winnie-the-Pooh, it is the original 1930 iterations of Betty Boop and Rover/Pluto that are entering the public domain. Newer, different versions of the characters are still copyrighted, and trademark rights still cover the character names and designs when they are used on merchandise as brand signifiers. The rules are complex and explored in more detail here, with their application to Betty Boop discussed here

Among the other highlights from 1930 are additional Mickey Mouse comic strips and cartoons, in which the famous mouse continues to develop, and the comic strip Blondie, featuring early versions of Blondie and Dagwood. In 1930 they are not yet married, and Dagwood has not yet discovered his signature sandwich.[6] Blondie’s maiden name is Boopadoop—similar to Betty Boop’s scat-singing catchphrase, which in turn echoed the phrase associated with the singer and actress Helen Kane and has been traced back to the African-American jazz performer “Baby” Esther Lee Jones. (Kane actually sued the Fleischers for appropriating the phrase, along with her persona and singing style. In response, the Fleischers claimed that Kane had copied those attributes from Esther Jones. The judge ruled against Kane. Based on the reports we can find, the accuracy of the specific claims and counterclaims is unclear, but accounts of Boop's creation indicate that the character was based at least partly on Kane.)[7]

War films, musicals, thrillers, Westerns, comedies, surrealist satires—this year’s newly public domain films run the gamut. They feature familiar actors: Marlene Dietrich, Greta Garbo, John Wayne, the Marx Brothers, and the film debut of Moe Howard and Larry Fine, who would later be long-running members of The Three Stooges. There are also familiar names among the directors and writers: Alfred Hitchcock, Howard Hughes, and even Rube Goldberg and Salvador Dalí.

These films predated the enactment of the 1934-1968 “Hays Code” that censored profanity, criminal activity, “indecent” dance costumes, and sexual content such as “excessive and lustful kissing, lustful embraces, suggestive postures and gestures.” In Morocco, Marlene Dietrich, handsomely dressed in a top hat and tails, famously kisses another woman. King of Jazz features the sequence “I Like to Do Things For You,” described on Wikipedia as “humorously sadomasochistic.” Pre-Code Betty Boop was overtly seductive. As critic Gabrielle Bellot wrote: “On the one hand, Betty Boop was a creation of the heterosexual male gaze, with an endless parade of lecherous male characters trying to see under her skirt, yet on the other hand she wore power like a light shawl, her image an in-your-face depiction of unashamed sexuality.”[8] Post-Code Betty Boop covered her shoulders and garter. As with Maugham’s Rosie from Cakes and Ale, frank female sexuality was not to be tolerated. Malvolio would have liked the Hays Code.

Some of the scenes from these films are eerily resonant today. In King of Jazz, a man gets drunk and stammers: “You know what’s the matter with this country? It’s a tariff! That’s who!”, referring to the 1930 Smoot-Hawley Tariff Act that deepened the Great Depression. Today, there is a lot of debate about whether the public knows enough about the importance of the rule of law and the protections of due process. At the end of Animal Crackers, Groucho and Chico Marx (as Captain Spaulding and Ravelli) have this exchange.

Groucho: “We go to court and get a writ of habeas corpus.”
Chico: “You gonna get rid of what?”
Groucho: “Haven’t you ever heard of habeas corpus?”
Chico: “No, but I’ve heard of ‘Habie’s Irish Rose’.”
Groucho sighs in exasperation and walks away

As Faulkner, the author whose novel begins this year’s list of books, wrote: “The past is never dead. It’s not even past.”

Cimarron is featured even though it was released in 1931 because it was copyrighted in 1930 and the earlier date controls (date discrepancies are resolved “in favor of the public”). Please note that only the original films from 1930 are public domain; later versions might have newly added material that is still copyrighted. If a film has been restored or reconstructed, only original and creative additions are eligible for copyright; if a restoration faithfully mimics the preexisting film, it does not contain newly copyrightable material. Putting skill, labor, and money into a project is not enough to qualify it for copyright, and the Supreme Court has made clear that “the sine qua non of copyright is originality.”

What about the music in the films? We are in the era when “talkies” – movies with sound – were new. As with other works, the statutory copyright terms for this music began either upon “publication” or copyright registration. If musical works were previously unpublished or unregistered and first appeared in a film from 1930, the general rule is that the music was published along with the film and is also public domain in 2026. (The same is true of the "sounds accompanying a motion picture," discussed below.) In other circumstances, however, a film and its underlying music may have different copyright terms. If a song was copyrighted separately before the film, for example, the song would have entered the public domain earlier than the film, after its own 95-year term. Conversely, if the copyright in the song was renewed while the copyright in the film was not, the song remained copyrighted after the film went into the public domain. This happened with It’s A Wonderful Life (1946)—the movie’s copyright was not renewed but the soundtrack’s copyright was, so the movie was public domain while the soundtrack and underlying short story were not. But if musical works made their first appearance in a film and the film rights were renewed, then the prevailing view is that the movie and music enter the public domain at the same time.[9]

MUSICAL COMPOSITIONS

1930 brought us enduring jazz standards and popular songs. From George and Ira Gershwin came I Got Rhythm, the source of the foundational jazz chord progression known as the “rhythm changes,” and But Not for Me, memorably featured in the film When Harry Met Sally (RIP Rob Reiner). You might still find yourself humming the classics Georgia on My Mind and Dream a Little Dream of Me today. Just A Gigolo offered an early, melancholy take on the proverbial player who’s “gonna play, play, play.”

Only the musical compositions—the music and lyrics that you might see on a piece of sheet music—are entering the public domain, not the recordings of those songs, which are covered by a separate copyright with a different term of protection. The lyrics and music to Georgia on My Mind and Livin’ in the Sunlight, Lovin’ in the Moonlight were published in 1930 and will be free for anyone to copy, perform, record, adapt, or interpolate into their own song.[10] But the later recordings by Ray Charles and by Tiny Tim are still copyrighted. (Readers may remember the Tiny Tim recording from the first episode of SpongeBob SquarePants—that episode had to be omitted from the first season DVD because the rights were not cleared with Tiny Tim’s estate.) Sound recording rights are more limited than composition rights, however. You can legally imitate a sound recording – should you be able to channel Tiny Tim’s signature falsetto – even if your imitation sounds exactly the same, you just cannot copy from the actual recording.

Calculating the copyright term for these early songs can be tricky. Under the law at the time, the copyright clock only started ticking when songs were published in sheet music form, not merely released as recordings. Even though Mood Indigo came out in 1930, the sheet music was not published until 1931, so it will not be in the public domain until 2027. If works were registered for copyright and published in different years, the earlier date controls. So copyright lapses over Dream a Little Dream of Me in 2026 because its copyright was registered in 1930, even though it was not published until 1931.

SOUND RECORDINGS

Under the 2018 Music Modernization Act, recordings from 1925 will be open for legal reuse after the conclusion of a 100-year term. There are some incredible performances: the civil rights icon Marian Anderson singing Nobody Knows the Trouble I’ve Seen in her haunting contralto, and The St. Louis Blues recorded by Bessie Smith and Louis Armstrong. Only the 1925 recordings made by these artists are entering the public domain, not their later recordings. To listen to old recordings, you can go to the Library of Congress National Jukebox.[11]

Sound recordings within a movie are treated differently from separate sound recordings because copyright law’s definition of “sound recording” specifically excludes “sounds accompanying a motion picture.” So the 1930 recordings as they appeared in the film King of Jazz have the same copyright term as the movie and are public domain in 2026, while regular sound recordings from 1930 that were independent of motion pictures have the 100-year term and their copyrights won’t expire until 2031.

ART

Copyright will also expire in 2026 over works of art that were published or registered in 1930, reflecting artistic movements ranging from Art Deco to Constructivism and Neoplasticism. In the traumatic years of World War I, Paul Klee wrote that “the more horrifying this world becomes, the more art becomes abstract.” Artists such as Klee, Mondrian, Taeuber-Arp, and van Doesburg abstracted the world around them: stylizing, simplifying, flattening, and deconstructing. But the artists on our list also include José Clemente Orozco, whose intensely realistic Prometheus was described by Jackson Pollock as “the greatest painting in North America,” and Edward Steichen, who went on to revolutionize minimalism in commercial fashion photography.

Determining the copyright status of older artworks is challenging. They are only public domain in 2026 if they were “published” as defined by copyright law in 1930, and it is often unclear when exactly publication occurred.[12] The rules are murky and “published” is a legal term of art that was not well-defined. Generally the law looks at whether the art was genuinely released to the public by being exhibited without restrictions on copying, circulated in a magazine or catalogue with authorization, or offered for sale to the public. If it was created but remained only in the artist’s studio or shown only to a limited group, this did not count. But artistic records from almost 100 years ago are difficult to find. Our tireless research assistant Jason Rosenberg spent months contacting experts and combing through exhibition catalogues, museum archives, journals, catalogue raisonnés, provenance indexes, auction records, and biographies to confirm whether the highlighted works were published in 1930.

There are other legal wrinkles too. Works by US artists had to comply with copyright “formalities,” including initial publication with a copyright notice and renewal after 28 years, to enjoy the full 95-year term. This is why American Gothic – which is from 1930 – is not on our list; it was by an American artist, Grant Wood, and entered the public domain in 1958 when its copyright was not renewed. Foreign authors such as Mondrian and Klee are treated differently—because of a 1996 provision that restored copyright over certain foreign works, they are eligible for the full term without notice or renewal. For such authors, the question is whether their works were actually “published” in 1930.[13]

You may see reports that the Chrysler building is entering the public domain in 2026 because it was constructed in 1930. The building was reportedly scrubbed from the 2023 Spider-Man 2 video game because of a copyright claim. However, there is no legal basis for such a claim. US copyright law only covers buildings created on or after December 1, 1990, when protection was first extended to architectural works. And even with newer copyrighted buildings, the law allows “pictorial representations of the work, if the building in which the work is embodied is located in or ordinarily visible from a public place.” So if the Spider-Man story is true, it would be an example of copyright overreach or overly cautious avoidance.

Here is a short video celebrating the works entering the public domain in 2026.

WHY CELEBRATE THE PUBLIC DOMAIN

When works go into the public domain, they can legally be shared, without permission or fee. Community theaters can screen the films. Youth orchestras can perform the music publicly, without paying licensing fees. Online repositories such as the Internet Archive, HathiTrust, Google Books, and the New York Public Library can make works fully available online. This helps enable both access to and preservation of cultural materials that might otherwise be lost to history. 1930 was a long time ago and the vast majority of works from that year are not commercially available. You couldn’t buy them, or even find them, if you wanted. When they enter the public domain in 2026, anyone can rescue them from obscurity and make them available, where we can all discover, enjoy, and breathe new life into them.

The public domain is also a wellspring for creativity. You could think of it as the yin to copyright’s yang. Copyright law gives authors important rights that encourage creativity and distribution—this is a very good thing. But the United States Constitution requires that those rights last only for a “limited time,” so that when they expire, works go into the public domain, where future authors can legally build on the past—reimagining the books, making them into films, adapting the songs and movies. That’s a good thing too! It is part of copyright’s ecosystem. The point of copyright is to promote creativity, and the public domain plays a central role in doing so.

The Supreme Court explained: “The copyright term is limited so that the public will not be permanently deprived of the fruits of an artist’s labors.” To quote Justice Joseph Story, this benefits the public by “admitting the people at large, after a short interval, to the full possession and enjoyment of all writings . . . without restraint.”

How does the public domain feed creativity? Here are just a few current illustrations. In 2025 you may have enjoyed Guillermo del Toro’s Frankenstein, derived from Mary Shelley’s novel, or Wicked: For Good, derived from L. Frank Baum’s The Wonderful Wizard of Oz. Perhaps you are looking forward to Christopher Nolan’s forthcoming epic IMAX version of The Odyssey, Wuthering Heights starring Margot Robbie as Catherine Earnshaw, or Lear Rex, a new version of King Lear starring Al Pacino as Lear. The Great Gatsby entered the public domain in 2021 and has already spawned a number of creative reworkings. 2025 saw others join them. We had The Gatsby Gambit, The Great Mann, Local Heavens, and Mrs. Wilson's Affair: A Great Gatsby Retelling. Clearly, this is a public domain work on which today's novelists have been feasting. Shakespeare, Dickens, and Austen continue to spawn adaptations too, including a reimagining of Hamlet in present-day London, A Far Better Thing (A Tale of Two Cities with fairy changelings), and The Season of Dragons (Pride and Prejudice and dragons). We haven't yet read it, but very much hope it contains the line, "It is a truth universally acknowledged, that a single dragon in possession of a good hoard of treasure, must be in want of a wife." 

The works we are celebrating from 1930 also illustrate how the public domain nurtures creativity. Once again, a fine exemplar is Disney, whose beloved works, from Snow White and Cinderella to The Jungle Book and Sleeping Beauty, have consistently built upon the public domain. That was as true in 1930 as it is today. The Mickey Mouse cartoons from 1930 made ingenious reuse of public domain music. Here are some of the public domain songs from these works: Morning, Night and Noon in Vienna by Franz von Suppé (1844), the William Tell Overture by Gioachino Rossini (1829), Orphée aux Enfers by Jacques Offenbach (1858), A Hunting We Will Go by Thomas Arne (1777), Oh Susanna and Old Folks at Home/Swanee River by Stephen Foster (1848, 1851), The Farmer in the Dell (1820s) and Pop Goes the Weasel (1850s) (traditionals), and a tune known as the Snake Charmer Song (1840s). All of these compositions date from before 1880, when the maximum copyright term was 42 years, and could be freely used in 1930 animations.

Sometimes people worry that entry into the public domain could mean the desecration of a beloved character or plot. Yes, inevitably there will be those who capitalize on public domain status to make deliberately shocking content—the slasher movie based on Winnie the Pooh comes to mind, or the low-budget horror films featuring Mickey Mouse. Works like that may even generate outrage—that is their whole marketing plan! But will they be remembered? We have always been able to make slasher or porn versions of Shakespeare, yet I am guessing that the Shakespearean adaptations you remember are Rosencrantz and Guildenstern Are Dead (from Hamlet, RIP Tom Stoppard), West Side Story (from Romeo and Juliet), Forbidden Planet (from The Tempest), or 10 Things I Hate About You (from The Taming of the Shrew). From the serious to the whimsical, these are public domain reuses with more enduring appeal. Far from dimming the luster of the original works, they have allowed their legacy to live on. The best reason not to care about the merely shocking use of public domain works, without an underlying artistic point, is that they tend not to stand the test of time. 

This point is true far beyond Shakespeare. Think of all the other films, cartoons, books, plays, musicals, video games, songs, and other works based on Greek mythology, on Mary Shelley’s Frankenstein, or on the works of Austen and Dickens. The Odyssey inspired not only the upcoming Christopher Nolan epic and the title of As I Lay Dying, but also centuries of other remakes—The Adventures of Huckleberry Finn, Ulysses, and the Coen brothers’ O Brother Where Art Thou, to name just a few.

Note that the public domain extends beyond works whose copyrights have expired. Some material is born in the public domain. Ideas, facts, and raw data can never be copyrighted. The public domain also includes official works of the US government such as legislation, legal opinions, and even NASA images. The images from the James Webb telescope, the NASA collections NASA on The Commons (flickr) and NASA image and video library, the famous “Earthrise” photograph taken by astronaut William Anders, and the Farm Security Administration - Office of War Information Photograph Collection (a pictorial record of American life from 1935-1944 that includes Dorothea Lange's powerful photograph "Migrant Mother," one of the enduring images of the Great Depression) are all copyright-free. Another category of public domain material consists of works that creators choose to dedicate to the public domain, and many have done so using Creative Commons’ CC0 tool.

HOW DO COPYRIGHT AND TRADEMARK LAW APPLY TO CHARACTERS?

It's Public Domain Day! Start your creative enginesWhen Mickey Mouse 1.0 went into the public domain in 2024, he joined a host of other public domain characters—Winnie-the-Pooh, Sherlock Holmes, Snow White, Cinderella, Dracula, Frankenstein's Monster, Robin Hood, Santa Claus, and the Wonderful Wizard of Oz characters, to name a few. This year, we get the first versions of Betty Boop and Pluto (originally named Rover) and new iterations of Mickey and Minnie Mouse. Looking ahead, an exciting new cast of characters will become public domain in the coming years: the initial appearance of Goofy in 2028 (originally named Dippy Dawg), Donald Duck in 2030, Superman in 2034, Batman in 2035, Tom and Jerry and Bugs Bunny in 2036, and Wonder Woman in 2037. 

Long-running characters such as Betty Boop and Mickey Mouse are subject to both expired and enduring rights. This creates a fascinating checkerboard of material that is free and still owned. The overall result is a layered mosaic of public domain and copyrighted character attributes. Here is a summary, with the legal rules spelled out in more detail afterward and applied to Betty Boop

Character Checkerboard

Beginning with Mickey Mouse as a concrete example, dozens of iterations of the mouse fall into each of the categories above. In the top left quadrant, we will have 24 Mickey cartoons (from 1928-1930) and 6 comic strips (1930) that have entered the public domain due to copyright expiration after the full term. At the top right, there are also non-renewed cartoons and over a thousand additional comic strips just from 1930-1935 that appear to be public domain due to non-renewal. And in the bottom row, there are decades of still-copyrighted works, as well as continuing trademark rights for the use of Mickey’s image on various Disney products.

The non-renewed works in the top right quadrant present an additional legal twist. The only aspects that became public domain upon non-renewal were their new features, not material derived from earlier works that remained in-copyright. The chronology of owned and free in such works is inverted. The new is free; the old may be subject to copyright.

Princess MinnieHere is how this nuance plays out in one Mickey story without a renewed copyright—the 1934 tale of Rumplewatt the Giant. This story introduces a gnome village from which the titular giant steals a golden goose. After Mickey defeats the giant, the butterfly who initially flew him to the castle morphs into Princess Minnie. As a reward for his valiance, she agrees to marry Mickey. So far as we can tell, these elements were newly introduced in the 1934 comic. If this is correct, they are in the public domain due to non-renewal.

GiantlandAt the same time, Rumplewatt the Giant derived many of its elements from the still-copyrighted cartoon Giantland (1933). These include a sequence where Mickey hides in a sugar-cube jar and ends up in the giant’s coffee cup, and a bit where Mickey uses pepper to make the giant sneeze. Assuming these were original to Giantland, they are still copyrighted. Even though they reappear in the non-renewed comic, they are not in the public domain because they originated in a work that is still under copyright. Finally, both works share basic “ideas” that are uncopyrightable and were always in the public domain—these include the generic “hero fights a giant and defeats him” plot line.

BETTY BOOP 

Betty Boop provides another illustration. As Betty Boop 1.0 enters the public domain, this is an opportunity to celebrate and appreciate Max and Dave Fleischers’ unparalleled artistry and pioneering animation. While Fleischer Studios may not be as well-known to the general public as Disney, perhaps they should be.

We know that Boop’s initial appearances from 1930 are public domain in 2026. There are also dozens of post-1930 Betty Boop cartoons that have long been public domain due to non-renewal. And there are many still-copyrighted works featuring Boop, plus trademark rights over her name and depiction for certain products.

Fleischer Studios has posted a statement called “Fact Check 2026: Is Betty Boop in the Public Domain?". It begins with "this year Betty Boop appeared on a number of [public domain] lists, claiming that she will enter the public domain on January 1, 2026, which is actually not true" and elaborates:

While the copyright in the ‘Dizzy Dishes’ cartoon may fall into the public domain in 2026, this does not affect Fleischer Studios’ copyright in the fully developed BETTY BOOP character Fleischer Studios created in subsequent cartoons and other uses and continues to use today. Fleischer Studios’ copyright in that character will therefore remain in force for some years to come, as will Fleischer Studios’ copyrights in the many subsequently revised and modern versions of the BETTY BOOP character and related elements. Equally important, the BETTY BOOP name and various related character designs are well-known and valuable Fleischer Studios trademarks.

boop4.pngboop5.pngThis is interesting because while Fleischer Studios does own continuing trademark rights over Betty Boop (discussed below), its claim to copyright over the fully developed character is less clear. In fact, in 2011, an appeals court definitively held that Fleischer did not own the copyright in the Boop character.[14] The original Fleischer Studios had gone out of business and sold off its rights in the 1940s. The current Fleischer Studios, “a distinct and separate entity,” had later tried to buy back those rights. The only issue before the court was whether Fleischer owned the familiar Boop character. The court ruled that, because “the chain of title is broken,” it did not. (Beside the text you can see, from the court exhibits, two versions of Boop that Fleischer did not then own. As you can see, they are more “modern” than the 1930 Boop with her subtle dog ears.) Perhaps Fleischer has since reacquired some of those rights, or perhaps they only have the rights over newly added features from the “subsequent cartoons and other uses” they mention. In the latter case, those rights would be narrow and would not extend to the underlying Boop character at issue in the 2011 decision. One thing is clear: regardless of who owns the later versions of the character, the original Betty Boop character from 1930 is in the public domain.

If your head is spinning from all the complexities involved here, congratulations! You are in good company. This is another reason why copyright expiration is so important: It brings clarity. There can be multiple separate copyrights implicated in a single creative work – over characters, audiovisual content, music, and so on. During a copyright term that lasts almost 100 years, those multiple rights may have changed hands many times and may no longer be owned by a single entity, or indeed by any entity we can identify. It can be incredibly difficult to figure out who owns what. When entire works become public domain, they are free for reuse without having to untangle this web of ownership.

Thankfully, now that Betty Boop 1.0 is public domain, the ownership and chain of title questions are immaterial. She, at least, is copyright-free. That brings us to another set of questions: What features of the newer, copyrighted Boop characters are still subject to exclusive ownership, and what is free to the public? Expanding on the checkerboard above, here are more specifics about the legal rules, and how they apply to Betty Boop.

EXPIRED AND SUBSISTING COPYRIGHTS

We begin with the left column on the checkboard above. When the copyright expires over a creative work, the characters within that work enter the public domain, and you can use them in new works without permission or fee. What if those characters also appear in more recent works that remain copyrighted?

First, under US copyright law, anyone is free to use characters as they appeared in public domain works. If those characters recur in later works that are still under copyright, the rights only extend to the newly added material in those works, not the underlying material from the public domain works—that content remains freely available.

Second, with newer versions of characters, copyright only extends to those new features that qualify for such protection. The features must be “original, creative expression,” meaning that they were independently created (as opposed to copied from somewhere else) and possess at least a modicum of creativity. Mere “ideas” such as generic character traits are not copyrightable. Nor are “merely trivial” or “minuscule” variations added to the original characters. It is not enough for the new material to be different; it has to meet copyright’s threshold requirements for protectability. In addition, using commonplace elements that have become standard or indispensable (copyright law calls these “scènes à faire”) is not infringement.[15] Finally, if your use qualifies as “fair use,” for example if you make a scathing parody that significantly transforms the original work, the copyright owner has no right to stop you.

From what we have said so far, you can see that even when a work is still under copyright, the rightsholder’s control is not absolute. Here is a serendipitous example. In Nichols v. Universal (1930), the author of the play Abie’s Irish Rose (mentioned above as part of the Marx Brothers’ pun) sued the producers of a popular movie for copyright infringement, claiming appropriation of her characters and plot. The judge rejected this claim, invoking as an example Shakespeare’s Sir Toby Belch from Twelfth Night, the source of W. Somerset Maugham’s Cakes and Ale title highlighted earlier. The judge wrote:

If Twelfth Night were copyrighted, it is quite possible that a second comer might so closely imitate Sir Toby Belch or Malvolio as to infringe, but it would not be enough that for one of his characters he cast a riotous knight who kept wassail to the discomfort of the household, or a vain and foppish steward who became amorous of his mistress. These would be no more than Shakespeare’s “ideas” in the play, as little capable of monopoly as Einstein’s Doctrine of Relativity, or Darwin’s theory of the Origin of Species.

Applying this to Abie’s Irish Rose, the judge explained why copying two lovers from the play would not be infringement: “The lovers are so faintly indicated as to be no more than stage properties. They are loving and fertile; that is really all that can be said of them, and anyone else is quite within his rights if he puts loving and fertile lovers in a play of his own, wherever he gets the cue.”

How do these legal rules apply to Betty Boop? BOOP! the Musical was made when the character was still under copyright. Permission needed to be obtained. What if you wanted to make your own different Betty Boop musical in 2026, now that Boop 1.0 is in the public domain?

All of Boop’s features from the 1930 cartoons are public domain in 2026. In her first appearance in Dizzy Dishes, she has the familiar flapper girl appearance and dance moves, and sings variations of “Boop Oop a Doop” to the besotted Bimbo character.

 Boop2.pngBoop3.pngThat Betty Boop is in the public domain, along with the lyrics, plot, and incredible animation. So are the Boops from other 1930 cartoons (to the left, Barnacle Bill and Mysterious Mose). However, those are not the only parts of the character in the public domain. Some of her features were not copyrightable from the beginning, because they were copied from elsewhere. Her general appearance and “Boop Oop A Doop” catchphrase were inspired by the Jazz Age flapper girl archetype, as embodied by celebrities such as Helen Kane.[16] It was the way those came together into a captivating new character that was copyrighted and is now entering the public domain.

Here is how Betty Boop developed over time, from Fleischer Studios' "Becoming Betty Boop" website.

booptimeline.png

What features of newer Betty Boops are copyrightable? While copyright still covers the overall post-1930 depictions of Boop, it does not extend to unoriginal, “merely trivial,” or stereotypical modifications of Boop 1.0, such as replacing the dog ears with human ones, dressing her in standard attire for a cabaret performer or homemaker, adding a Rosie the Riveter bandana, or modulating her voice to reflect newer singing styles.

We went through this same process two years ago with Mickey Mouse. Mickey 1.0 did not have red shorts or speak in a high-pitched voice; those traits were added in later, still-copyrighted works. When the original Mickey became public domain, we were asked by many reporters whether creators could color his shorts red or have him talk in a falsetto. Are those variations, standing alone, copyrightable? Does choosing a single, bright, primary color for an article of clothing, or giving an animated mouse a squeaky voice (given that mice actually squeak), meet the copyrightability threshold? We would say no, but reasonable people could disagree on exactly where the line is to be drawn.

Let us be clear: None of this detracts from the astounding creativity in the Fleischer cartoons—they are some of the most innovative cartoons we have ever seen! The later works contain a wealth of copyright-eligible material such as plot lines, dialogue, and new characters. But with any creative work – as the quote about Twelfth Night demonstrates – there are also uncopyrightable building blocks that remain free for future creators. The challenge is to separate the copyrightable wheat from the uncopyrightable chaff.

NON-RENEWED COPYRIGHTS

We now turn to the top right quadrant in the checkerboard—the plot thickens when we add works that are also in the public domain due to non-renewal. Under early copyright law, copyrights lapsed after 28 years if they were not renewed. Dozens of post-1930 Betty Boop cartoons, including Ker-Choo (1932) and Poor Cinderella (1934), did not have renewals.[17] The newly added material in these animations is also in the public domain. As mentioned earlier, however, the material derived from still-copyrighted Boop animations is not.[18]

To sum up the copyright story so far: in 2026, the underlying Betty Boop character goes into the public domain. She is joined there by the attributes, plot lines, and dialogue that were first introduced in those later cartoons without renewed copyrights, as well as the uncopyrightable attributes of her later instantiations.

WHAT IF THE CHARACTER IS NO LONGER COPYRIGHTED, BUT ITS NAME OR IMAGE IS STILL SUBJECT TO TRADEMARK RIGHTS?

We finish with the bottom right quadrant: trademarks. You may encounter claims that even though Betty Boop 1.0 is copyright-free in 2026, you still cannot use the character in new creative works because it is trademarked by Fleischer Studios. But this is not what the law actually says. While Fleischer’s trademark rights over Betty Boop are unaffected by her entry into the copyright public domain, those rights are limited. Trademark law only prohibits the use of a trademarked character if doing so “is likely to cause confusion, or to cause mistake, or to deceive” consumers about the source or sponsorship of a new product.[19] Here is a brief summary of the relevant law.

  • Trademark rights are designed to prevent consumer confusion in the marketplace. They are not supposed to interfere with artistic expression that doesn’t create such confusion. Trademark law does not prevent you from using a public domain character’s name or image in a new creative work so long as consumers are not likely to be misled into thinking that your work is produced or sponsored by the trademark holder. In addition, the law has special rules that allow creators to use other people’s trademarks in artistic works without liability.[20]
  • Trademarks do not override copyright law.The Supreme Court has made clear that trademark rights cannot be used to block the freedoms that the expiration of copyright allows, such as using a public domain character in a book or movie.[21]
  • → Therefore, trademark rights do not prevent you from using the 1930 Betty Boop character in a new creative work unless consumers will be confused into thinking it is a Fleischer-sponsored product.

That is the précis; here is the expanded version for those who are interested. Copyrights and trademarks are different. Copyrights cover creative works and prevent people from copying and adapting them without permission, with the goal of providing economic incentives to create and distribute cultural material. The US Constitution requires that these rights expire after a “limited time,” so that the public and future creators can have unfettered access to creative works.

Trademarks cover words, logos, images, and other signifiers that serve as brands identifying the source of a product. The goal is to minimize consumer confusion in the marketplace. Nike can prevent other producers of athletic apparel from putting “Nike” or a swoosh on their merchandise so that when purchasers see those indicators, they know they are getting a Nike product.

Unlike copyrights, trademarks do not automatically expire. They can last as long as a mark is still being “used in commerce.” While trademarks can outlast copyrights, however, the rights themselves are more circumscribed. It is only trademark infringement if an unauthorized use is likely to create consumer confusion about a product’s source or sponsorship. Non-confusing uses are not prohibited, and there are a variety of legal safeguards for uses of trademarks in connection with expressive works such as films, books, and songs.

Sometimes copyrights and trademarks overlap. A character such as Betty Boop might be covered both by copyright law (as a creative work) and trademark law (as an indicator of product-source). What happens when the copyright expires and the trademark is ongoing? In a unanimous opinion, the Supreme Court made clear that trademarks cannot be used to make an end run around copyright law because this would “create a species of mutant copyright law that limits the public’s federal right to copy and to use expired copyrights.”

“We have been careful to caution against misuse or overextension of trademark and related protections into areas traditionally occupied by . . . copyright.” Dastar v. Twentieth Century Fox (Supreme Court 2003)

In other words, trademark rights cannot be used to block the freedoms that the expiration of copyright allows, such as using a public domain character in a new creative work. Along the same lines, the Ninth Circuit Court of Appeals explained that when a work enters the public domain “[w]e all own it now,” and trademark law “cannot be used to circumvent copyright law. If material covered by copyright law has passed into the public domain, it cannot then be protected by the Lanham Act [the federal trademark statute] without rendering the Copyright Act a nullity.”[22]

Therefore, you can use a character’s name or image in a new creative work so long as consumers do not think that your work is produced or sponsored by the trademark holder. Those who tell you otherwise are mistaken.[23] One way to help dispel potential confusion is to make clear the actual source of the work – you or your company – on the title screen or cover, along with a prominent disclaimer indicating that your work is not produced, sponsored, endorsed, licensed, or approved by the trademark owner.

Betty Boop ImageFleischer owns trademark rights to the words “Betty Boop” and “Boop” for products such as live musical theater performances and clothing. It also has trademarks over Betty Boop designs such as the one depicted here for a range of merchandise including jewelry, wallets, back packs, drinking glasses, plastic water bottles, clothing, and dolls. (As noted by the Ninth Circuit appeals court in the case rejecting Fleischer’s copyright claim, it turns out that Boop merchandise is extremely popular, even appearing in the most surprising locations: “This merchandise has reached such a high level of popularity that even drug dealers have been known to use it. See United States v. Lakoskey, 462 F.3d 965, 971 (8th Cir. 2006) (‘A search warrant was issued, and the package was opened pursuant to that warrant on January 26, 2004. The package contained a large ceramic Betty Boop doll, with four concealed, separately wrapped plastic bundles of high-purity-level methamphetamine inside’).”)

Fleischer’s trademark rights are for uses of “Betty Boop,” “Boop,” and her image, but only in connection with particular specified products. Fleischer does not own the simple word “Boop,” unconnected to Betty. Other companies have federally registered “Boop” as a trademark for coffee mugs and pet stores. Trademarks do not convey ownership of a word. “Popeye” the sailor cartoons coexist happily with the unconnected “Popeyes” chicken and biscuits. Dove soap does not infringe Dove chocolate. Delta faucets and Delta airlines legally use the same brand name for different goods and services.

The result of all of these points is that Fleischer Studios cannot use trademark law to interfere with the production of a new creative work featuring the Betty Boop 1.0 character when it is clear that the new work is not a Fleischer-sponsored production.

Here it is important to distinguish between different uses of the Boop character. Certainly, there would be a risk of consumer confusion if you use Betty Boop as a brand identifier on the kind of merchandise Fleischer sells—jewelry, back packs, water bottles, dolls. Trademark law does protect Fleischer against that risk.

Contrast these uses with simply putting the Boop character in a new artistic work. This is exactly what copyright expiration is intended to allow. Were trademark law to prevent this, then trademark rights would be leveraged to obtain the effective equivalent of a perpetual copyright—precisely what the Supreme Court said we cannot do. You can also use the trademarked terms “Betty Boop” or “Boop” in connection with the new work featuring that character. As one court explained:

“When a public domain work is copied, along with its title, there is little likelihood of confusion when even the most minimal steps are taken to distinguish the publisher of the original from that of the copy. The public is receiving just what it believes it is receiving—the work with which the title has become associated. The public is not only unharmed, it is unconfused.”[24]

If courts have delineated the line between copyright and trademark, why is there so little clarity in this area? Sadly, companies sometimes claim to have more expansive rights than they actually do, capitalizing on fear, uncertainty, and doubt to collect royalties and licensing fees to which they are not legally entitled. This is deeply regrettable. It interferes with the rights of everyone from the small community theater trying to screen a public domain movie, and being told they still have to pay licensing fees, to new creators trying to make a new work from a public domain character but facing baseless threats that they are infringing. In the process, it fundamentally misstates the law in a way that confuses the public.

When such overbroad claims have actually gone to court, they have been dismissed, sometimes harshly. In 2023 we covered the Sherlock Holmes saga. The ingenious detective and his faithful sidekick Dr. Watson had been in the public domain for a long time. But that did not stop Conan Doyle Estate Ltd. from demanding licensing fees. Most people simply paid up. But when Leslie Klinger, a lawyer and Sherlock Holmes scholar, fought back, a court decisively confirmed that all of the elements in the out-of-copyright Sherlock Holmes stories are “free for public use.” The estate appealed, in a move that the Seventh Circuit Court of Appeals described as bordering on the “frivolous” and “quixotic.” The appeals court affirmed Klinger’s right to use the Holmes and Watson characters and awarded him attorney’s fees. Judge Richard Posner called out the estate’s “unlawful business strategy”:

The Doyle estate’s business strategy is plain: charge a modest license fee for which there is no legal basis, in the hope that the “rational” writer or publisher asked for the fee will pay it rather than incur a greater cost, in legal expenses, in challenging the legality of the demand…only Klinger (so far as we know) resisted. In effect he was a private attorney general, combating a disreputable business practice — a form of extortion…It’s time the estate, in its own self-interest, changed its business model. Klinger v. Conan Doyle Estate (7th Cir. 2014).

Let us hope that 2026 does not see more of this type of disreputable legal overreach.

WHAT IS THE IMPACT OF THE LONG COPYRIGHT TERM?

For copyrighted culture, the public domain arrives only after a long wait. Works from 1930 were first set to go into the public domain after a 56-year term in 1986, but a term extension pushed that date to 2006. They were then supposed to go into the public domain in 2006, after being copyrighted for 75 years. But before this could happen, Congress hit a 20-year pause button and extended their copyright term to 95 years. Now the wait is over.

The works featured above are famous; that is why we included them. Their copyright holders benefitted from 20 more years of copyright because the works were still earning royalties. But they are just the tip of the iceberg. When Congress extended the copyright term for these works, it also did so for all of the works whose commercial viability had long lapsed. For the vast majority—probably 99%—of works from 1930, no copyright holder financially benefited from continued copyright. Yet they remained off limits, for no good reason.

A Congressional Research Service report indicated that only around 2% of copyrights between 55 and 75 years old retain commercial value. After 75 years, that percentage is even lower. Most older works are “orphan works,” where the copyright owner cannot be found at all.

This is why a former head of our Copyright Office concluded that adding an extra 20 years to the US copyright term was a “big mistake.” Indeed, there is a consensus among policymakers, economists, and academics that lengthy copyright extensions impose costs that far outweigh their benefits. Why? The benefits are minuscule—economists (including five Nobel laureates) have shown that term extension does not spur additional creativity. At the same time, it causes enormous harm, locking away millions of older works that are no longer generating any revenue for the copyright holders. Films have disintegrated because preservationists can’t digitize them. The works of historians and journalists are incomplete. Artists find their cultural heritage off limits.

The public domain enables the rediscovery and reuse of works that might otherwise be forgotten. Empirical studies have shown that public domain books are less expensive, available in more editions and formats, and more likely to be in print—see here, here, and here. The works highlighted above are just a tiny snapshot of what will be copyright-free. Many more are waiting to be found and appreciated.

While the arrival of works into the public domain is cause for celebration, the length of the copyright term means that even though works from 1930 are legally available, this does always not mean they are actually available. Many films from the era have been lost forever. Noteworthy lost or mostly lost films from 1930 include the sound version of John Ford’s Men Without Women and The Gorilla

The fact that works from 1930 are legally available also does not mean that rights holders won't continue to claim copyright over them. The previous section mentioned what an appeals judge called the "disreputable business practice" of charging "license fee[s] for which there is no legal basis." Yet rights holders continue to claim copyright over public domain properties. Lloyd Entertainment has told small community theaters that, unless the pay licensing fees, they cannot screen Safety Last! – a silent film that went into the public domain in 2019 – even when the theaters are using their own music and thought they were playing public domain prints. Lloyd claims that no public domain versions of the film exist because all available copies have been restored. Not all restorations have new copyrights, however. As mentioned earlier, if a film has been restored, only original and creative additions are eligible for copyright. If the restoration faithfully mimics the preexisting film, it does not contain newly copyrightable material and can be screened just like the public domain version. Many restorations contain new copyrightable material, but is it possible that every surviving print of Lloyd's movies is both restored, and sufficiently creatively changed to acquire a new copyright? The fact that this is in doubt underscores the problem with the long copyright term: after nearly a century, works may be legally available, but it is difficult to find original versions. Harold Lloyd was brilliant and the rights holders to his films enjoyed 95 years of copyright exclusivity. But when that term expires, theaters should be able to screen the films—this is exactly what the public domain is supposed to allow. It is disappointing to know that rights holders are targeting people who are merely trying to show films to fans, out of love and respect for the art.

To take a similar example, the owners of the rights to Charlie Chaplin’s films have been sending aggressive letters to small theaters telling them that they cannot screen Chaplin films that are legally in the public domain. The letters contain assertions about US copyright law that are, to use the technical term, bogus. To be sure, Chaplin was a genius and his successors have legitimate rights over his still-copyrighted films. But they do not have the right to squelch activities that are entirely legal. As Judge Posner commented earlier, falsely claiming an entitlement to licensing fees over public domain works can be "a form of extortion." 

The Chaplin Office nevertheless claims that the 1925 film The Gold Rush cannot be screened because the copyright in the underlying screenplay does not expire until 70 years after Chaplin’s death, or the end of 2047, because Chaplin was British and his copyright was restored under special rules for works by foreign authors. (They focus on the screenplay because the film entered the public domain in 1953 due to non-renewal of its copyright.) Even if this copyright restoration met the law's requirements (it does not appear to) there is a more basic mistake in their calculation: they cite to the wrong provision of US copyright law, §303, for the life + 70 term, ignoring that it is only for works that were “created but not published or copyrighted before January 1, 1978.” The Copyright Office records show that the screenplay was copyrighted in 1925, and for such works the law states that the copyright lasts for “the remainder of the term of copyright that the work would have otherwise been granted in the United States,” which is 95 years under §304 of the Copyright Act, making the work public domain in 2021. Case closed.

WHAT ARE THE BASIC RULES FOR DETERMINING WHETHER SOMETHING IS PUBLIC DOMAIN?

How long does copyright last in the United States? The 1998 Copyright Term Extension Act gave works published or registered before 1978 a 95-year term, expiring on January 1 after the conclusion of the 95th year. Doing the math, you add 96 years to the publication date. Works from 1930 were copyrighted for 95 years—through 2025—and are in the public domain January 1, 2026. This year's featured works are in the public domain because of either a 1930 registration or publication with a 1930 copyright notice. We were also able to track down the renewal data indicating that they are still in-copyright through the end of 2025 and entering the public domain in 2026.

Works published before 1978 had to meet certain requirements to be eligible for the full 95-year term—they had to be published with a copyright notice, and works from before 1964 also had to have their copyrights renewed after an initial 28-year term. Works published from 1978 through 3/1/1989 without a notice had to register their copyrights within five years to fix the lack of copyright notice. This means that many works published after 1930 might technically be in the public domain. However, as a practical matter, users sometimes have to assume they’re still copyrighted (or risk a lawsuit) because the relevant copyright information is difficult to find. We do not have clear and comprehensive records of copyright ownership and older records can be fragmentary, confused, or lost. In addition, as mentioned earlier, the concept of "publication" is important and has a special meaning under copyright law. It refers to when the work was sold or distributed to the general public with the authority of the copyright owner. Determining whether and when publication occurred can be complicated and vary depending on the kind of work—with music from before 1978, for example, the distribution of recordings of a song did not publish the song. 

For pre-1978 works that were never published or registered, the term is different: life-plus-70 years for works by natural persons, and 120 years from creation for works of corporate authorship. In this category, works created by people who died in 1955 are in the public domain in 2026. Newer works created since 1978 are also treated differently from those published before 1978. Works by natural persons from 1978 forward have a life-plus-70 term, while works of corporate authorship are copyrighted for 95 years after publication. This is the copyright term for works created today, and there are no longer notice or renewal requirements. 

What about foreign works? Some countries have a life-plus-50 term and many others, including EU countries, have a life-plus-70-year term, even for the older works that have the 95-year term in the US. This means that works might be copyrighted in one country and copyright-free in another. For example, W. Somerset Maugham’s Cakes and Ale enters the US public domain in 2026 but is still copyrighted elsewhere until 2036, because the author died in 1965. In life-plus-70 jurisdictions, works from authors who died in 1955 are public domain this year, so they are celebrating a different set of works on Public Domain Day. How do you know which law applies to you? As a general matter, courts have said that users are governed by the law in the jurisdiction where they are using the creative work. But this inquiry can be more complicated and depend on the circumstances surrounding the use.

In the US, many foreign works from 1930 are copyrighted until 2026 because of a provision that, in 1996, restored copyright over certain foreign works that had fallen into the US public domain because of non-compliance with notice or renewal requirements. This restored term applies to many of the foreign works we are highlighting. You can learn more about how this functions from the Copyright Office's circular Copyright Restoration Under the URAA. If the owners of copyright in foreign works filed a Notice of Intent to Enforce their restored copyright you can find that information here. You can also find copyright restoration records through the Copyright Office’s search portal here.

Rumor Alert! You may see inaccurate claims online that all works by non-US authors such as Charlie Chaplin, Alfred Hitchcock, or Hergé are not entering the US public domain because they are subject to a life + 70 copyright term. This is not true. The 1996 provision that restored US copyright over qualifying foreign works is clear that their copyrights last for “the remainder of the term of copyright that the work would have otherwise been granted in the United States.” For foreign works that were published or copyrighted in 1930 – such as the ones we highlight – this term is 95 years, and they enter the public domain in 2026.

What is the copyright term for sound recordings? The Music Modernization Act’s “Classics Protection and Access Act” established a timeline for old recordings to enter the public domain. Recordings first published between 1923–1946 are public domain in January 2024–2047 (the year after a 100-year term). Then there is a ten-year pause from 2048–2058. After that, recordings first published between 1947–1956 are public domain in January 2058–2067, after a 110-year term. The term for all remaining recordings first fixed from 1957 until February 15, 1972 ends on February 15, 2067. Note that the term of protection for sound recordings in other countries is different from the one in the US: in the EU it is 70 years, and elsewhere it is 50 years. 

CONCLUSION

This year’s entrants into the public domain are a wonderful group—enthralling, and deeply entertaining. Whatever your artistic interest, they have some delicious “cakes and ale” for you. Malvolio would disapprove. But they also offer us something deeper. 

Language and art were once domains that humans thought solely our own. Generative AI has forced us to re-articulate our conception of art and the creative process; to focus on the subjective experience behind the work, not just the pretty patterns manifested within it. In that context, it is fascinating to reflect on these works from 1930. What leaps out at you is the humanity behind them—the wit, the stylistic innovation, the stories being told in the shadow of World War I and in the midst of the Great Depression. 

These authors were producing meaning from lived experience, not just replicating patterns. Their artistic output is not merely a snapshot of our culture at a moment in time or an entertaining postcard from the past. It is a record of the lives they lived, the emotions they felt, and the art they made as a result of it. It gives new meaning to the Somerset Maugham quote with which we began this essay, speaking of the beauty that artists sometimes create out of chaos. “The pictures they paint, the music they compose, the books they write, and the lives they lead. Of all these the richest in beauty is the beautiful life. That is the perfect work of art.” In the age of AI, those words seem to offer us a luminous insight.

[2] Our featured works are only entering the public domain under US copyright law. The copyright term for older works is different in other countries. In the EU, works from authors who died in 1955 are going into the public domain in 2026 after a life-plus-70 year term. As a general matter, under the principle of lex loci delicti, users are governed by the law in the jurisdiction where they are using the creative work. See Itar-Tass Russian News Agency v. Russian Kurier, Inc. (2d Cir. 1998). But this inquiry can be complicated and fact-specific, and governing law will depend on the circumstances of the use in question. 

[3] Even though a work is still in-copyright, you may legally use it in certain ways if your activity qualifies for copyright’s “fair use” exception.

[4] To find more material from 1930, you can visit the Catalogue of Copyright Entries. In the US, only the author’s works from 1930 and earlier are in the public domain, not all of the other work published by that author. With regard to newly copyright-free works, only the original versions published in 1930 are entering the US public domain. Later versions of them—adaptations, movies, or translations—may still be copyrighted. However the later copyright only covers newly added creative material. The original content from the 1930 work remains free. As you look through these works from 1930, please note that they offer a temporal cross section of our cultural past, capturing the era in its complexity. Unfortunately many of the works from 1930 contain racist and sexist stereotypes and demeaning language. When such works enter the public domain, anyone is free to critique and remake them, even if doing so goes beyond what would be allowed under copyright’s fair use doctrine.

[5] Arnold Munk credited a book called “The Pony Engine” (1916) but later faced an unsuccessful claim that he took the story from Frances Ford who had written a similar story in 1910. For fascinating research into the stories that led up to Munk’s version, see Roy Plotnick, “In Search of Watty Piper: The History of the ‘Little Engine’ Story,” New Review of Children’s Literature and Librarianship, 18:11-26 (2012).

[7] Peter Benjaminson, The Life and Times of Betty Boop: The 100-Year History of an Animated Icon (Rowman & Littlefield Publishers, 2023), p17: “Early one morning in 1930, Dave Fleischer told animator Grim Natwick to design a girl dog who would costar with Bimbo in a cartoon to be titled ‘Dizzy Dishes.’ Natwick was told that the new character, as yet unnamed, would be singing a ‘boop-oop-a-doop’ song similar to those sung by Helen Kane. Fleischer also handed Natwick a picture of Kane.” The lyrics from the song that Boop sings in Dizzy Dishes are from “I Have to Have You,” performed by Helen Kane in a film the year before. Animation Resources recounts similar origins in this biography of Grim Natwick

[8] You can find Bellot’s quote and a more in-depth analysis of the Betty Boop character before and after the Hays Code in Emily Wishingrad, “The Evolution of Betty Boop”, Smithsonian Magazine (March 9, 2022). Bellot further explained that "[Betty Boop] was a stereotype, yet she also defied stereotypes of what female cartoon characters could do onscreen. In The Life and Times of Betty Boop, Peter Benjaminson writes: “Betty is the only classic female comic character who isn’t someone’s wife, girlfriend, or regular employee. Unlike Olive Oyl, Blondie, and other cartoon women, Betty’s not defined by her relationship to a male character…She’s her own woman, known for herself, and not just because she belongs to some man.” 

[9] Here is additional information on the question of when musical compositions were “published” under early copyright law. We know that they were published when copies of sheet music were sold, and were not published if they were merely distributed as sound recordings. But what if the music first appeared in a movie? While courts have offered inconsistent interpretations of the law, the leading copyright treatise explains that the “general rule” is that publication of a movie also publishes the previously unpublished works incorporated within the movie, such as music and screenplays. 1 Nimmer on Copyright § 4.12. Cases following this rule include Shoptalk, Ltd. v. Concorde-New Horizons Corp. (2d Cir. 1999), Batjac Prods. Inc. v. GoodTimes Home Video Corp (9th Cir. 1998) and Maljack Prods. Inc. v. UAV Corp. (C.D. Cal. 1997). The logic is that publication of the film necessarily entails publication of its constituent parts. See Classic Film Museum, Inc. v. Warner Bros., Inc. (D.Me.1978) (“It is impossible to cleave the story, screenplay and musical score of a motion picture film from the film itself”; holding that non-renewal of the original 1937 film A Star Is Born “dedicated the film in its entirety [including the script and musical score] to the public use”). If the film’s owners complied with the legal requirements for the full 95-year copyright term, the owners of the underlying material in the film received that protection as well. When the term expires, the motion picture and its component parts become public domain, allowing use of the composite film.

The Copyright Office agrees with this interpretation. In a 1975 review of the 1909 Copyright Act, which governed works from 1930, it explained: “On the basis of a thorough legal review and analysis of the status of motion picture soundtracks under the copyright statute, the Copyright Office has concluded that under the prevailing judicial view, copyright in a motion picture extends to an integrated sound track and its copyrightable component parts.” 37 C.F.R. § 202.15 (1975). Accordingly, under the 1909 Act, “[t]he U.S. Copyright Office considers a motion picture to be a unitary work in which the component parts are integral to the work as a whole.” Copyright Office Compendium § 2122.6(C). This remains true under today’s copyright law: “Where music is first published in a motion picture soundtrack, the motion picture is considered a copy of the musical work.” Copyright Office Compendium § 802.4(C).

There are cases that departed from this general rule, but they did so in a different context. See Richlin v. Metro-Goldwyn-Mayer Pictures, Inc. (9th Cir. 2008); TCA TV Corp. v. McCollum (2d Cir. 2016). These decisions did not afford the works embodied in a film the full copyright term, so that the composite entered the public domain after 95 years. Instead, they did the opposite, and said that the owners of such underlying works forfeited their copyrights because they could not benefit from the film owners’ compliance with copyright formalities. Criticizing this “harsh construction” of the law, Professor Nimmer invokes a scenario relevant to this discussion: “the fact that a songwriter may separately register her work for protection does not prove that her failure to separately register the work forfeits all protection in it—the possibility remains that she could rely on the registration of the work in which the song appears to vindicate her rights in that song.” After these rights expire, both the film and song go into the public domain.

The popular songs in King of Jazz were copyrighted separately from the film and either entered the public domain before 2026, as with My Bridal Veil (1920), Rhapsody in Blue (1924), Mississippi Mud (1927), and The Bluebirds and the Blackbirds Got Together (1929), or are from 1930 and are becoming public domain along with the film—these include A Bench in the Park, The Song of the Dawn, Happy Feet, I Like to Do Things for You, It Happened in Monterey, Ragamuffin Romeo, and Music Has Charms (all from 1930).

[10] Note that US copyright law allows you to cover a song without permission while it is still copyrighted under the “compulsory license” in §115, so long as you do not “change the basic melody or fundamental character” of the original song and pay a pre-set royalty rate. When a song is in the public domain you can make covers without complying with this provision, and you can also make other adaptations, performances, and interpolations.

[11] The Music Modernization Act sets a timeline for older recordings to enter the public domain, and also has provisions allowing people to legally make noncommercial uses of still-copyrighted recordings that are no longer being commercially exploited. Older recordings contain a wealth of history; not just music but spoken word, radio broadcasts, oral histories. A lot of this material has faded into obscurity and is of interest primarily to scholars and hobbyists. But, like old films, old audio lives on a fragile substrate—many vintage formats deteriorate over time, to the point where they literally disintegrate, or it is impossible to play them again. Congress therefore included carveouts in the law to try and ensure that this history can be digitized and preserved for future generations. 

[12] For never-published, never-registered works, the term is life + 70 years.

[14] In the 2011 case Fleischer Studios v. A.V.E.L.A., the Ninth Circuit Court of Appeals held that Fleischer Studios was not the owner of the copyright to the Betty Boop character. The original Fleischer Studios sold those rights away and was dissolved in the 1940s. The rights in the Betty Boop character were carved out from the rights in the cartoons and the separate sets of rights were eventually transferred to different companies. Later the Fleischer heirs formed a new Fleischer Studios – “a distinct and separate entity from the now defunct Original Fleischer which first owned Betty Boop” – and tried to buy back the copyright to the Betty Boop character. There was a complicated chain of title: “Original Fleischer transferred its rights to Paramount Pictures, Inc. (Paramount) in 1941; Paramount transferred those rights to UM & M TV Corp. (UM & M) in 1955; in 1958, UM & M transferred these rights to National Telefilm Associates, Inc. (NTA), which became Republic Pictures in 1986; and finally, Republic Pictures transferred the exclusive copyright to Fleischer in 1997.” The problem? There is a broken link in the chain: “it is clear that Paramount did not transfer the copyright to the Betty Boop character to UM & M.” Because the copyright was kept by Paramount, rather than transferred to UM & M, UM & M could not transfer it down the line to Fleischer. Something could have happened since this 2011 decision – for example, Fleischer could have regained rights directly from Paramount – but we cannot find anything in the legal filings or Copyright Office records and do not know who now owns the rights at issue in A.V.E.L.A. If Fleischer owns copyrights in later cartoons, this would only confer rights over character features that were not derived from the iterations it does not own. Suffice it to say that the scope of their copyright claims is unclear, and any copyright actions against others would necessarily be limited to uses that infringe on what they actually own.

[15] To quote the Copyright Office primer on derivative works: “[I]t is not possible to extend the length of protection for a copyrighted work by creating a derivative work…the copyright in the derivative work will not extend to the public domain material, and the use of the public domain material in a derivative work will not prevent anyone else from using the same public domain work for another derivative work.”

[16] See the Copyright Office Compendium. Regarding generic character traits, courts have held that being “nice,” having a “cocky attitude,” and being “young, attractive, and sarcastic” are not independently copyrightable character traits. See Shame on You Prods. v. Banks (C.D. Cal. 2015, aff’d 9th Cir. 2017); Campbell v. Walt Disney Co. (N.D. Cal. 2010); Gable v. Nat’l Broad. Co. (C.D. Cal. 2010).

[18] See Stewart v. Abend (1990). 

[19] 15 U.S.C. §§1114, 1125(a). A small subset of superbrands with “famous” marks gets extra protection against “dilution” that impairs the distinctiveness or harms the reputation of the famous mark, even when there is no consumer confusion. This protection is limited to “famous” marks, as defined by trademark law. Fame has a specialized meaning here: only trademarks that are widely recognized by the general public as a brand signifier qualify. It is not enough that a character is famous in the general sense of the word. Instead, its depiction would need to function like the Nike Swoosh in designating product source. Importantly, even for trademarks that qualify, anti-dilution protection is subject to statutory First-Amendment exceptions that allow for the kinds of expressive uses discussed in this section. See 15 U.S.C. §1125(c)(3). For instance, even though “Barbie” is a famous mark that qualifies for anti-dilution protection, the statutory exceptions in §1125(c)(3) have allowed artists to use the “Barbie” trademark for artistic commentary.

[20] Trademark law has a number of speech-protecting limitations that safeguard artistic uses. These apply whether or not the trademark is also the subject of an expired copyright. One defense allows “nominative use” of a trademark as a point of reference – for example, using “Betty Boop” accurately to refer to the character in your work. Another comes from a case called Rogers v. Grimaldi, which privileged the use of trademarks in titles of expressive works when the term has some artistic relevance to the new work and does not explicitly mislead as to the source of the work. A 2023 Supreme Court decision let the Rogers test stand for these kinds of uses, see Jack Daniel's Properties, Inc. v. VIP Products LLC (2023), so long as the unauthorized use is not as a brand signifier. These doctrines are why Mattel loses in court when it sues people for using the word “Barbie” and the doll’s trademarked appearance in expressive works. See Mattel, Inc. v. Walking Mountain Productions (9th Cir. 2003); Mattel, Inc. v. MCA Records, Inc. (9th Cir. 2002). While a disclaimer is not required to benefit from these limitations, it can nevertheless be useful to make abundantly clear that you are not providing an official Fleischer Studios production. 

[21] Dastar v. Twentieth Century Fox (2003) (“We have been careful to caution against misuse or overextension of trademark and related protections into areas traditionally occupied by . . . copyright”). This case dealt with an attempt to make an attribution-like claim under the federal trademark statute over public domain works, but the larger policy underlying the decision is that trademark law cannot be used to circumvent copyright expiration. Dastar had repackaged parts of a public domain documentary, removing the original credits and presenting it as a Dastar production. Twentieth Century Fox owned the copyrights to the documentary before they expired and claimed that Dastar violated trademark law by passing off Fox’s work as its own and failing to attribute it to Fox. The Supreme Court rejected this claim.

[22] Comedy III v. New Line (9th Cir. 2000). Nonetheless, people sometimes still try to use trademark law to interfere with legal reuses of public domain material, leading to unnecessary litigation and chilling effects. Zorro Productions, Inc. and Edgar Rice Burroughs, Inc. did this with the Zorro works and the Tarzan and John Carter works. Zorro lost in court—because the Zorro story was in the public domain, a new “Queen of Swords” TV series about Zorro’s sword-wielding daughter could proceed. See Sony v. Fireworks (C.D. Cal. 2001) (the case also included unsuccessful copyright claims). Burroughs was able to extract a joint licensing deal from the publisher of new “Lord of the Jungle” and “Warlord of Mars” comic books; even the threat of lawsuits can chill creative reuse.

[23] The leading treatise on trademark law explains: “The expiration of copyright on a copyrighted work, such as a motion picture containing a cartoon character, should place limits on the scope of trademark rights in the character. Under the view that upon expiration of copyright the public should have free use of the work, copyright policy requires that anyone should be able to reproduce, display and perform the out-of-copyright motion picture so long as there is no confusion as to the source, sponsorship or affiliation of the seller of the reproduced film,” and “a court should not permit trademark in an image to serve the same function as did the lapsed copyright to exclude others from reproducing and distributing the out-of-copyright work, such as a film . . . a balancing of the rights of trademark and of the 'public domain' status of out-of-copyright works is needed. A similar balancing is made when constitutional free speech policies are balanced against the prevention of consumer confusion.” J. Thomas McCarthy, McCarthy on Trademarks and Unfair Competition, § 6.30.

See also Walt Disney Productions v. Souvaine Selective Pictures, Inc. (S.D.N.Y. 1951, aff'd 2d Cir. 1951) (Disney could not prevent another film producer from using the title “Alice in Wonderland” because “the book ‘Alice in Wonderland’ is no longer subject to copyright and is as much in the public domain as are Shakespeare’s plays. Anyone has a legal right to make a picture based on Lewis Carroll’s book and entitled ‘Alice in Wonderland’”).

Say No to Palantir in the NHS

notopalantir.goodlawproject.org - Comments

NHS England is rolling out software to run our health records from Palantir – a US spy-tech firm that has supported mass deportation in the US and enabled genocide in Gaza.

One of Palantir’s founders is also openly against the NHS. Peter Thiel claimed it “makes people sick” and said that the British people love the NHS because we’re suffering from Stockholm syndrome.

We can’t let a company like this take control of our healthcare system.

But we can fight back right now. We’ve set up a simple tool so you can find out if your local NHS trust has started using the software, and then send an email demanding they say no to Palantir.

With the government putting NHS trusts under pressure to adopt the software, we need to act right now. If you want to keep Palantir out of our NHS, send an email to your local trust and Wes Streeting, secretary of state for health.

How we lost communication to entertainment

ploum.net - Comments

by Ploum on 2025-12-15

All our communication channels are morphed into content distribution networks. We are more and more entertained but less and less connected.

A few days ago, I did a controversial blog post about Pixelfed hurting the Fediverse. I defended the theory that, in a communication network, you hurt the trust in the whole network if you create clients that arbitrarily drop messages, something that Pixelfed is doing deliberately. It gathered a lot of reactions.

When I originally wrote this post, nearly one year ago, I thought that either I was missing something or Dansup, Pixelfed’s creator, was missing it. We could not both be right. But as the reactions piled in on the Fediverse, I realised that such irreconcilable opinions do not arise only from ignorance or oversight. It usually means that both parties have vastly different assumptions about the world. They don’t live in the same world.

Two incompatible universes

I started to see a pattern in the two kinds of reactions to my blog post.

There were people like me, often above 40, who like sending emails and browsing old-fashioned websites. We think of ActivityPub as a "communication protocol" between humans. As such, anything that implies losing messages without feedback is the worst thing that could happen. Not losing messages is the top priority of a communication protocol.

And then there are people like Dansup, who believe that ActivityPub is a content consumption protocol. It’s there for entertainment. You create as many accounts as the kinds of media you want to consume. Dansup himself is communicating through a Mastodon account, not a Pixelfed one. Many Pixelfed users also have a Mastodon account, and they never questioned that. They actually want multiple accounts for different use cases.

On the Fediverse threads, nearly all the people defending the Pixelfed philosophy posted from Mastodon accounts. They usually boasted about having both a Mastodon and a Pixelfed account.

A multiplicity of accounts

To me, the very goal of interoperability is not to force you into creating multiple accounts. Big Monopolies have managed to convince people that they need one account on each platform. This was done, on purpose, for purely unethical reasons in order to keep users captive.

That brainwash/marketing is so deeply entrenched that most people cannot see an alternative anymore. It looks like a natural law: you need an account on a platform to communicate with someone on that platform. That also explains why most politicians want to "regulate" Facebook or X. They think it is impossible not to be on those platforms. They believe those platforms are "public spaces" while they truly are "private spaces trying to destroy all other public spaces in order to get a monopoly."

People flock to the Fediverse with this philosophy of "one platform, one account", which makes no sense if you truly want to create a federated communication protocol like email or XMPP.

But Manuel Moreale cracked it for me: the Fediverse is not a communication network. ActivityPub is not a communication protocol. The spec says it: ActivityPub is a protocol to build a "social platform" whose goal is "to deliver content."

The ActivityPub protocol is a decentralised social networking protocol based upon the ActivityStreams 2.0 data format. It provides a client to server API for creating, updating and deleting content, as well as a federated server-to-server API for delivering notifications and content. (official W3C definition of ActivityPub)

No more communication

But aren’t social networks also communication networks? That’s what I thought. That’s how they historically were marketed. That’s what we all believed during the "Arab Spring."

But that was a lie. Communication networks are not profitable. Social networks are entertainment platforms, media consumption protocols. Historically, they disguised themselves as communication platforms to attract users and keep them captive.

The point was never to avoid missing a message sent from a fellow human being. The point was always to fill your time with "content."

We dreamed of decentralised social networks as "email 2.0." They truly are "television 2.0."

They are entertainment platforms that delegate media creation to the users themselves the same way Uber replaced taxis by having people drive others in their own car.

But what was created as "ride-sharing" was in fact a way to 1) destroy competition and 2) make a shittier service while people producing the work were paid less and lost labour rights. It was never about the social!

The lost messages

My own interpretation is that social media users don’t mind losing messages because they were raised on algorithmic platforms that did that all the time. They don’t see the point in trusting a platform because they never experienced a trusted means of communication.

Now that I write it, it may also explain why instant messaging became the dominant communication medium: because if you don’t receive an immediate answer, you don’t even trust the recipient to have received your messages. In fact, even if the message was received, you don’t even trust the recipient's attention span to remember the message.

Multiple studies have confirmed that we don’t remember the vast majority of what we see while doomscrolling. While the "view" was registered to increase statistics, we don’t have the slightest memory of most of that content, even after only a few seconds. It thus makes sense not to consider social media as a means of communication at all.

There’s no need for a reliable communication protocol if we assume that human brains are not reliable enough to handle asynchronous messages.

It’s not Dansup who is missing something. It is me who is unadapted to the current society. I understand now that Pixelfed was only following some design decisions and protocol abuses fathered by Mastodon. Pixelfed was my own "gotcha" moment because I never understood Instagram in the first place, and, in my eyes, Pixelfed was no better. But if you take that route, Mastodon is no better than Twitter.

Many reactions pointed, justly, that other Fediverse tools such as PeerTube, WriteFreely, or Mobilizon were just not displaying messages at all.

I didn’t consider it a big problem because they never pretended to do it in the first place. Nobody uses those tools to follow others. There’s no expectation. Those platforms are "publish only." But this is still a big flaw in the Fediverse! Someone could, using autocompletion, send a message pinging your PeerTube address and you will never see it. Try autocomplete "@ploum" from your Mastodon account and guess which suggestion is the only one that will send me a valid notification!

On a more positive note, I should give credit to Dansup for announcing that Pixelfed will soon allow people to optionally "not drop" text messages.

How we lost email

I cling to asynchronous reliable communications, but those are disappearing. I use email a lot because I see it as a true means of communication: reliable, asynchronous, decentralised, standardised, manageable offline with my own tools. But many people, even barely younger than me, tell me that email is "too formal" or "for old people" or "even worse than social network feeds."

And they are probably right. I like it because I’ve learned to use it. I apply a strong inbox 0 methodology. If I don’t reply or act on your email, it is because I decided not to. I’m actively keeping my inbox clean by sharing only disposable email addresses that I disable once they start to be spammed.

But for most people, their email inbox is simply one more feed full of bad advertising. They have 4 or 5 digit unread count. They scroll through their inbox like they do through their social media feeds.

Boringness of communications

The main problem with reliable communication protocols? It is a mostly solved problem. Build simple websites, read RSS feeds, write emails. Use IRC and XMPP if you truly want real-time communication. Those are working and working great.

And because of that, they are boring.

Communications protocols are boring. They don’t give you that well-studied random hit of dopamine. They don’t make you addicted.

They don’t make you addicted which means they are not hugely profitable and thus are not advertised. They are not new. They are not as shiny as a new app or a new random chatbot.

The problem with communication protocols was never the protocol part. It’s the communication part. A few sad humans never wanted to communicate in the first place and managed to become billionaires by convincing the rest of mankind that being entertained is better than communicating with other humans.

As long as I’m not alone

We believe that a communication network must reach a critical mass to be really useful. People stay on Facebook to "stay in touch with the majority." I don’t believe that lie anymore. I’m falling back to good old mailing lists. I’m reading the Web and Gemini while offline through Offpunk. I also handle my emails asynchronously while offline.

I may be part of an endangered species.

It doesn’t matter. I made peace with the fact that I will never get in touch with everyone. As long as there are people posting on their gemlogs or blogs with RSS feeds, as long as there are people willing to read my emails without automatically summarising them, there will be a place for those who want to simply communicate. A protected reserve.

Rainbow Six Siege is currently facing a major crisis, with mounting evidence pointing to a large scale hack or exploit, even as Ubisoft continues to describe the situation as a server incident. The disruption has now escalated into full service outages across all platforms, according to Ubisoft’s own service status page.

Players across PC and console are being urged by the community to stay offline, as reports continue to surface of accounts receiving billions of in game credits, rare and developer only skins, and experiencing random bans.

BREAKING: Ubisoft Rainbow Six Siege servers have been breached.

Players are reporting massive amounts of R6 Credits, Renown, Alpha Packs, and exclusive items unexpectedly.

Ubisoft Confirms Widespread Outages Across All Platforms

The official service status page for Rainbow Six Siege now shows critical issues across every major platform.

On PC, PS4, PS5, Xbox One, and Xbox Series X|S, core services including authentication, in game store access, and matchmaking are all listed as being in outage, while overall connectivity is marked as degraded. Ubisoft states that issues are being investigated, but has not provided a timeline for recovery.

The scale of the outages has further fuelled claims that this is far more serious than routine server instability.

Ubisoft’s Statement Draws Heavy Criticism

Earlier, the official Rainbow Six account acknowledged that it was aware of an incident affecting the game and said teams were working on a resolution. No mention was made of a security breach, hack, or exploit.

We’re aware of an incident currently affecting Rainbow Six Siege. Our teams are working on a resolution.

We will share further updates once available.

— Rainbow Six Siege X (@Rainbow6Game) December 27, 2025

That wording has been met with heavy backlash from players, many of whom believe Ubisoft is attempting to downplay the severity of the situation. Community responses have accused the publisher of calling it a server issue while core systems appear compromised.

Some players also questioned why the game remained online for hours while accounts were being altered in real time.

Players Report Billions of Credits, Dev Skins, and Ban Chaos

As the incident unfolded, players reported logging in to find their accounts flooded with billions of R6 Credits and Renown, thousands of Alpha Packs, and access to exclusive cosmetics such as developer skins and Glaciers.

Why is nobody talking about what is happening on Siege right now? Everyone that logs in gets 2 Billion R6 credits, Renown, Developer Skins and Glaciers 😭 pic.twitter.com/9SBiLdrirm

— Terd (@Terdsta) December 27, 2025

There were also widespread claims that the in game ban feed had been taken over, displaying arbitrary messages. Thousands of accounts were reportedly banned and unbanned at random, including those belonging to streamers and high profile players.

— Pirat_Nation 🔴 (@Pirat_Nation) December 27, 2025

Prominent Siege creator KingGeorge described the situation as completely broken, warning players not to log in and strongly advising against spending any currency, as it could lead to bans or rollbacks once Ubisoft regains control.

Btw as a side note I would not login right now, definitely don’t spend any credits or renown could lead to a ban.

— KingGeorge (@KingGeorge) December 27, 2025

Community Expects Rollbacks, Fears Punishment

With authentication and account systems affected, many players now expect Ubisoft to roll accounts back to a previous state. However, fears remain that innocent players could still face penalties, especially those who unknowingly spent credits thinking the issue was a visual glitch.

Others argue that banning a significant portion of the active player base would be disastrous, adding further pressure on Ubisoft to handle the aftermath carefully.

The lack of clear communication has only intensified frustration, with players demanding transparency about what actually happened.

What Players Should Do Right Now

Until Ubisoft confirms the issue is fully resolved and explains the cause, players are strongly advised to stay offline, avoid logging in, and do not spend any credits or Renown if access is restored.

With Rainbow Six Siege’s core services offline worldwide and player accounts potentially compromised, this incident could have lasting implications for the game if not handled properly. Ubisoft is expected to provide further updates as its investigation continues.

Windows 2 for the Apricot PC/Xi

www.ninakalinina.com - Comments

(and Word, and Excel, and so much more) by Nina Kalinina, December 27th, 2025 (rev. 1.01 2025-12-27)

I bought my first Apricot PC about three years ago, when I realised I wanted an 8086-based computer. At the time, I knew nothing about it and simply bought it because it looked rad and the price was low. I had no idea that it was not IBM PC-compatible, and that there were very few programs available for it.

I have been on a quest to get a modern-ish word processor and spreadsheet program for it ever since. Which eventually made me "port" Windows 2 on it. In this post, I will tell you the story of this port.

As a side-quest, I also wrote an article explaining why Windows 2 is kind of awesome. Make sure to check it out, too, if you need more Windows 2 screenshots in your life.

If you own an Apricot PC, or want to try the port in an emulator, check out the project on sr.ht. You need an Apricot PC, PC/Xi or Xen with at least 512 kB of RAM.

If you find technical details boring the heck out of you, please don't hesitate to scroll down to the screenshot section.




A few words about the Apricot PC/Xi

If you want a personal computer today, your general choice is between a "PC" and a "Mac". Back in the 1980s, you would have to choose between dozens or even hundreds of computer architectures, and "PC" was not necessarily the most popular choice for a computer. One of the most promising market contenders, Victor 9000, also known as Sirius 1, was released in 1981. It gained popularity in Europe, creating a niche market for "Sirius-compatible" computers. Two years later, the British company ACT released its Sirius-compatible Apricot PC.

0001.jpg

Apricot PC is a delightful computer with a great design. Its heart is Intel 8086, the older sibling of the 8088 used in the IBM PC. It uses lovely 3.5" floppy disks; and it is the first Western computer to have a 3.5" drive - before Apple Macintosh. The screen is 9 inches, 800x400 pixels, with great image fidelity. The PC/Xi model comes with a 10 megabyte Winchester hard drive, British-made Rodime RO352, the first-ever 3.5" hard drive.

0001a.jpg

A photograph of the computer's display showing multiple images at once: photographs of computer chips, schematics, and oscilloscope charts.

The computer is simple enough to be understood by one person in its entirety (over the course of many months of studying). There are schematics, technical manuals, BIOS reference manuals, and example code available for it, too. Its CPU is supported by Microsoft C, Turbo Pascal, and Open Watcom. It even runs MS-DOS (2.0 to 3.20), though, of course, it cannot run any IBM PC programs.

The lack of IBM PC-compatibility proved to be fatal for the Apricot. The entirety of its software catalogue is less than 300 megabytes. There is only one graphical game with a soundtrack for it, and it was made in 2025.

There were, of course, productivity applications for the Apricot, including Microsoft Word for DOS. But among those, only two word processors had a graphical interface: GEM Write and Microsoft Write for Windows 1. Neither were popular; GEM drivers were lost and re-created by John Elliot in 2012 or so. Windows 1 was thought to be lost.

Hypothetically, it should be possible to port a 16-bit Windows to this computer. It would require creating SYSTEM.DRV, DISPLAY.DRV, KEYBOARD.DRV, MOUSE.DRV, and ideally COMM.DRV drivers. But that would be a lot of work.

0001b.jpg

A screenshot of Windows 1 Notepad. I didn't have a Windows 1 Write screenshot at hand, but trust me, it looks almost the same.

This is where things get interesting. A port of Windows 1 for the Apricot PC (released by ACT in 1987, a year before Windows 2) was miraculously preserved and surfaced online not that long ago. By itself, Windows 1 is unremarkable, as it does not have much useful software. But its driver architecture is not too different from Windows 2, so I thought it might be just about possible to make Windows 2 for the Apricot. And if I could somehow boot Windows 2, I'd be able to run Word, Excel, and Adobe Illustrator on my Apricot.

Well, it only took two and a half years to pull it off!

Porting Windows 2 on the Apricot

Booting, fast and slow

Even today, software historians are still arguing whether Windows 2.0 deserves to be called a major Windows update. It added dozens of new kernel features, but it barely changed the driver architecture of the system. The mouse and the keyboard drivers for Windows 2 would work fine on Windows 1, and vice versa. The CGA and EGA video drivers from Windows 1 would allow Windows 2 to boot, but could not render the fonts correctly.

0002a.png

A screenshot of Windows 2 for IBM PC with a broken video driver; all text on the screen is garbled.

A natural thing to try would be installing Windows 2 with the Apricot drivers for Windows 1. Except that there are no driver files.

When you install Windows 1 or 2 on your computer, the SETUP utility combines (links) the driver files with the kernel. It is called "fast boot" and is supposed to improve the boot times of the system. The result of the SETUP is two files, WIN100.BIN and WIN100.OVL. The BIN file is an EXE file in disguise, consisting of the Windows kernel and the system drivers. The OVL file has resources and code that the system uses only from time to time.

The Windows 1 port of Apricot was only ever distributed with the "fast boot". The individual driver files were not distributed, so we cannot use them.

The stub drivers

If there are no drivers, we can make some! Microsoft has a Driver Development Kit for Windows, also known as Windows DDK. The DDK comes with the drivers for the IBM PC, meant to be used as a reference for other platforms. With the help of the DDK, I implemented a stub video driver, and somehow got a stub mouse and system drivers. This was enough to confirm that Windows 2, indeed, can start on the Apricot PC without any patches to the kernel. I had my doubts about that, because Windows 2 comes with EMS memory support, and it might have been using something IBM PC-specific to test for it. Thankfully not.

0002.png

A screenshot of Windows 2 booting in the text mode. The file manager application simply dumps the list of files on the screen, without drawing any windows.

Trying to write a video driver

Now I could expand the drivers to support the Apricot PC. Keyboard, mouse, and even system drivers are small and simple. The real beast of a driver is DISPLAY.DRV, as it has to implement a large subset of the Windows graphical subsystem. With the reference display drivers, this should not be a problem, as long as the video card supports a graphical mode.

But the Apricot PC doesn't have a real graphical mode. It has a 50x25 "graphics screen" with a fake 16x16 font. This is a big problem.

0003a.png

A page of the Apricot technical reference explaining the organisation of the Video RAM.

The reference video driver from Microsoft makes many bold assumptions about the way video RAM is organised. With the display initialisation routines corrected, the image produced by the reference driver is still undecipherable.

0003.png

A screenshot of the MAME emulator, running Windows 2 on the Apricot. There are no windows, only stripes of black.

Writing a driver for such a video card is significantly more painful than designing a VGA-compatible video card for the Apricot. Maybe I return to the Apricot display driver project one day (for the Windows 3.0 port), but for now, I have given up on it.

Lose the battle, win the war: re-linking

I decided to abandon the video driver writing when I discovered that video drivers from Windows 1 work correctly in Windows 2 if the system has a font from Windows 1, too. This means if I could somehow extract a video driver from the WIN100.BIN/OVL, I would not need to reverse-engineer it to patch in the font support; it could work out of the box. But how?

The driver files in WIN100 are not "simply concatenated together": some parts from DISPLAY.DRV ends up in WIN100.BIN, and some in WIN100.OVL. Looking closely at those parts, I realised that the part in WIN100.OVL is identical to the Hercules driver. This gave me an idea: I can get a Hercules video driver; then I could extract CODE and DATA segments along with the Entry Table from the WIN100.BIN, and patch them into the Hercules driver. Unfortunately, not a single NE file format tool supported this use-case. I ended up writing my own tool NExus-relink to assist in this process; the tool is still incomplete, but it gave me enough leverage to finish the job manually.

For the video driver, I used a "combine" tool I made for NExus, and then manually patched in the offsets and lengths in the NE header (one for the entry table, two for the segments). Incredibly, this was enough to make Windows 2 happy about the display:

0004.png

A screenshot of Windows 2 running in the MAME emulator.

The same trick worked for the keyboard driver, but the mouse driver gave me a headache. I knew that when the mouse is not found, Windows doesn't display it on the screen, so I kept iterating on the driver, going deeper and deeper. The mouse driver has a relocation table of the OS Fixup type, and there are very few things written about it, so I wasn't sure if the driver was loading correctly.

I confirmed that the interrupt handler of the driver works, and was about to check the kernel source of the corresponding event handler when I discovered that, in fact, the mouse was working fine. It's just that the cursor wasn't displayed on the screen.

In Windows 1/2, the cursor is handled by the video driver to allow hardware acceleration and "hide cursor before taking a screenshot or drawing a bitmap". So, why is the video driver not drawing the cursor?

Windows DDK documentation has an answer: the mouse cursor drawing routines in the video driver are called by a timer routine, from the SYSTEM.DRV. I told about this to my fiancée, Atsuko, and she said: "Oh, you didn't notice the cursor wasn't blinking?"

Turns out, the timer routines in the SYSTEM.DRV were broken. The SYSTEM.DRV from Windows 1.0 cannot be used with Windows 2, so I implemented the Apricot PC SYSTEM.DRV using Windows DDK as a reference.

With this driver complete, I had Windows 2 working on my Apricot PC/Xi.

Welcome, welcome, let me show you around!

0010.jpg

I am greeted with the AUG logo when I power up my Apricot. I use the AUG BIOS because it supports the upgraded CPU, NEC V30, much better than the original one. Note that my machine has 896 kB of RAM.

0020.jpg

The PC/Xi comes with a single 720 kB floppy drive and a 10 MB hard drive. I have MS-DOS 3.20 installed on the hard drive.

0030.jpg

I have created a file called `win.bat` that simply starts the kernel.

0110.jpg

Welcome to Windows 2. I have GW Basic, Turbo Pascal, Windows 1, Windows 2, Word and Excel installed on the hard drive, and I still have almost 2 megabytes free.

0201.jpg

PC Paintbrush is one of the few programs that work on both Windows 1 and Windows 2. But it is more stable when running on top of Windows 2. Note that this is not Microsoft Paint (yet).

0202.jpg

I have to remind you that the screen is monochrome. Pixel dithering works really well on a 100 PPI 800x400 display, creating shades of grey from pixel patterns.

0210.jpg

The screen is 4:3, so the pixels are not square. I have to pre-process raster images so they would look right on the Apricot's screen. Vector images are fine, though.

0310.jpg

The default shell for Windows 2 is a bit too minimalistic to my taste. WANG's ClearView for Windows 2 brings a familiar to Windows 3 users PROGMAN-like experience to the Apricot.

0320.jpg

Windows 1 came with tiling windows; Windows 2 uses overlapping windows that quickly become a disorganised mess. ClearView's window manager can arrange the windows for you.

0330.jpg

Windows 2 control panel looks a bit funny in monochrome, but it is a powerful reminder that Windows supports 24-bit colour, which is important for printing and publishing.

0410.jpg

A side note: Apricot's keyboard had an LED in the logo before ThinkPad did.

0420.jpg

The MicroScreen and re-programmable keys are fully supported by the Windows keyboard driver. There is no ALT key, so "Close" is as close as we can get to pressing ALT+f4. Note that there is a hotkey for starting the XENTEL telephone accessory. The XENTEL button is somewhat similar to a Copilot button, except it can actually be useful in some situations.

0510.jpg

Microsoft Word for Windows. Word for DOS, a completely different program, was first released back in 1983. Word for Windows had its first release in late 1989 due to a non-competition agreement with Apple. The success of Word for Windows made Microsoft abandon Word for DOS and Word for Mac; all the new versions of Word were based on this Word.

0520.jpg

Word for Windows is surprisingly powerful for a brand-new product. There is a spellchecker, a page layout editor, and even support for macros. I have deleted the macros to save space on the hard drive, so the README file shows "Error!" where the macros were. The files created by Word for Windows 1.0 can be opened by modern office suites if you save as RTF.

0610.jpg

Microsoft Excel is a real deal-breaker. There is no other spreadsheet as powerful as Excel on the Apricot.

0620.jpg

Excel for Windows from 1988 looks almost exactly like Excel for Windows from 2018.

0630.jpg

My previous trip to Japan was planned between Google Docs and Excel for Windows 2 (I had to convert the file back and forth). I needed a few GB of RAM for Google Docs, and only a few hundred kilobytes for Excel.

0640.jpg

Excel Help is a hidden gem. It is a hypertext application that feels a lot like a web browser.

0650.jpg

I used the Help application to see how to create a stonks chart.

0670.jpg

Creating a stonks chart is surprisingly easy. There are 44 chart types, more than many modern programs offer.

0710.jpg

Until yesterday, Apricot PC had five graphical games: Chess, Where Is The Owl, Windows 1 Reversi, Windows 1 Minesweeper, and Windows 1 Risk. Now there are many more, including a solitaire and a Taipei mahjongg.

0810.jpg

That's it! There are many Windows 2 programs I have yet to try on the Apricot, but my quest for running modern-ish Word and Excel for Windows is finally over.

Nvidia's $20B antitrust loophole

ossa-ma.github.io - Comments

AIResearchOpinion/Mild HatingGeopolitical CirclejerkVenture Capital

"You're taking on a giant. What gives you the audacity?"

On November 5th, 2025, Groq CEO Jonathan Ross was asked why he was even bothering to challenge Nvidia. He didn't blink:

"I think that was a polite way to ask why in the world are we competing with Nvidia, so we're not. Competition is a waste of money; competition fundamentally means you are taking something someone else is doing and trying to copy it. You're wasting R&D dollars trying to do the exact same thing they've done instead of using them to differentiate."

49 days later, Nvidia paid $20 billion for Groq's assets and hired Ross along with his entire executive team.

Except this wasn't actually an acquisition, at least not in the traditional sense. Nvidia paid $20 billion for Groq's IP and people, but explicitly did NOT buy the company. Jensen Huang's statement was surgical: "While we are adding talented employees to our ranks and licensing Groq's IP, we are not acquiring Groq as a company."

That phrasing is the entire story. Because what Nvidia carved out of the deal tells you everything about why this happened.

Forget the AI doomer takes about a bubble forming, lets look into the actual reasons.

What Nvidia Actually Bought (And What It Didn't)

Nvidia acquired:

  • All of Groq's intellectual property and patents
  • Non-exclusive licensing rights to Groq's inference technology
  • Jonathan Ross (CEO), Sunny Madra (President), and the entire senior leadership team

Nvidia explicitly did NOT buy:

  • GroqCloud (the cloud infrastructure business)

GroqCloud continues as an independent company under CFO Simon Edwards. This is Nvidia's largest acquisition ever (previous record was Mellanox at $7B in 2019), and they structured it to leave the actual operating business behind. That doesn't happen by accident.

LPU vs TPU vs CPU: Why SRAM Matters

To understand why Nvidia paid anything for Groq, you need to understand the architectural bet Ross made when he left Google.

CPUs and GPUs are built around external DRAM/HBM (High Bandwidth Memory). Every compute operation requires shuttling data between the processor and off-chip memory. This works fine for general-purpose computing, but for inference workloads, that constant round-trip creates latency and energy overhead. GPUs evolved from graphics rendering, so they're optimized for parallel training workloads, not sequential inference.

TPUs (Google's Tensor Processing Units) reduce some of this overhead with larger on-chip buffers and a systolic array architecture, but they still rely on HBM for model weights and activations. They're deterministic in execution but non-deterministic in memory access patterns.

LPUs (Groq's Language Processing Units) take a different approach: massive on-chip SRAM instead of external DRAM/HBM. The entire model (for models that fit) lives in SRAM with 80 TB/s of bandwidth and 230 MB capacity per chip. No off-chip memory bottleneck. No dynamic scheduling. The architecture is entirely deterministic from compilation to execution. You know exactly what happens at each cycle on each chip at each moment.

This creates massive advantages for inference:

  • Llama 2 7B: 750 tokens/sec (2048 token context)
  • Llama 2 70B: 300 tokens/sec (4096 token context)
  • Mixtral 8x7B: 480 tokens/sec (4096 token context)

And 10x better energy efficiency because you're not constantly moving data across a memory bus.

SOTA model tokens/sec throughput on GPU inference Compare this to SOTA model tokens/sec throughput on GPU inference

Serious trade off though, only 14GB of SRAM per rack means you can't run Llama 3.1 405B. And LPUs can't train models at all. This is an inference-only architecture with limited model size support.

But here's what makes this interesting: if DRAM/HBM prices continue climbing (DRAM has tripled in a year I should've gone all in DRAM in Jan I'm done with indexes), and if inference becomes the dominant AI workload (which it is), SRAM-based architectures become economically compelling despite the size limitations. Most production AI applications aren't running 405B models. They're running 7B-70B models that need low latency and high throughput.

The $13.1B Premium and the Non-Traditional Structure

Groq raised $750 million in September 2025 at a post-money valuation of $6.9 billion. Three months later on Xmas Eve, Nvidia paid $20 billion through a "non-exclusive licensing agreement" that acquired all IP and talent while explicitly NOT buying the company.

That's a $13.1 billion premium (3x the September valuation) for a company valued at 40x target revenue (double Anthropic's recent 20x multiple) with slashed projections (The Information reported Groq cut over $1B from 2025 revenue forecasts).

The structure is the story. Traditional M&A would trigger:

  • CFIUS review (given Saudi contracts)
  • Antitrust scrutiny (Nvidia's dominant position)
  • Shareholder votes and disclosure requirements
  • Multi-year regulatory review

Non-exclusive licensing bypasses all of it. No acquisition means no CFIUS review. "Non-exclusive" means no monopoly concerns (anyone can license Groq's tech). No shareholder votes, minimal disclosure.

But in practice: Nvidia gets the IP (can integrate before anyone else), the talent (Ross + team can't work for competitors now), and the elimination of GroqCloud (will likely die without IP or leadership). The "non-exclusive" label is legal fiction. When you acquire all the IP and hire everyone who knows how to use it, exclusivity doesn't matter.

The question isn't just why Nvidia paid $13.1B more than market rate for technology they could build themselves (they have the PDK, volume, talent, infrastructure, and cash). The question is why they structured it this way.

The $13.1B premium bought five things a traditional acquisition couldn't:

  1. Regulatory arbitrage: Non-exclusive licensing avoids years of antitrust review. Structure the deal as IP licensing + talent acquisition, and regulators have no grounds to block it. This alone is worth billions in time and certainty.

  2. Neutralizing Meta/Llama: The April 2025 partnership gave Groq distribution to millions of developers. If Llama + Groq became the default open-source inference stack, Nvidia's ecosystem gets commoditized. Kill the partnership before it scales.

  3. Eliminating GroqCloud without inheriting Saudi contracts: Nvidia has invested in other cloud providers. GroqCloud was a competitor. Traditional acquisition would mean inheriting $1.5B worth of contracts to build AI infrastructure for Saudi Arabia, triggering CFIUS scrutiny. The carve-out kills GroqCloud while avoiding geopolitical entanglement.

  4. Political access: Chamath makes ~$2B (Social Capital's ~10% stake). Sacks looks good (major AI deal under his watch as AI Czar). Nvidia gets favorable regulatory treatment from the Trump administration. Timing it for Christmas Eve ensures minimal media scrutiny of these connections.

  5. Preempting other acquirers: Ross invented Google's TPU. If Google had acquired Groq and brought Ross back, they'd have the original TPU creator plus LPU IP. Amazon and Microsoft were also exploring alternatives to Nvidia GPUs. Better to pay $20B now than compete with Ross at Google/Amazon/Microsoft later.

Two speculative reasons worth considering:

  1. Blocking Google/Amazon/Microsoft from partnering with Groq: Both are developing custom AI chips (Trainium, Maia). If either had hired Ross + team or licensed Groq's tech, Nvidia's inference dominance faces a real challenger. If Google had acquired Groq and brought Ross back, they'd have the original TPU inventor plus LPU IP.

  2. Chiplet integration for future products: Nvidia might integrate LPU as a chiplet alongside GPUs in Blackwell or future architectures. Having Ross's team makes that possible. You can't integrate IP you don't own, and you can't build it without the people who invented it.

That's how business works when regulation hasn't caught up to structural innovation. Nvidia paid $6.9B for technology and $13.1B to solve everything else using a deal structure that traditional antitrust can't touch.

The Saudi Arabia Problem

In February 2025, Saudi Arabia committed $1.5 billion to expand Groq's Dammam data center. The publicly stated goal was supporting SDAIA's ALLaM, Saudi Arabia's Arabic large language model. The actual goal was Vision 2030: positioning the Kingdom as an AI superpower.

Groq built the region's largest inference cluster in eight days in December 2024. From that Dammam facility, GroqCloud serves "nearly four billion people regionally adjacent to the KSA." This isn't API access. This is critical AI infrastructure for a nation-state, funded by the Public Investment Fund, processing inference workloads at national scale.

According to Ross in the Series E announcement, Groq powers Humain's services including the Humain chat product and supported OpenAI's GPT-OSS model release in Saudi Arabia. Groq operates 13 facilities across the US, Canada, Europe, and the Middle East. Ross noted that capacity expanded more than 10% in the month before the funding announcement and all of that capacity was already in use. Customers were asking for more capacity than Groq could satisfy.

That creates a CFIUS (Committee on Foreign Investment in the United States) problem. A U.S. chip company, venture-backed by American investors, building sovereign AI capability for Saudi Arabia. If Nvidia had acquired GroqCloud outright, they would inherit those contracts and the regulatory scrutiny that comes with them. Foreign investment reviews, export control questions, congressional inquiries about why an American company is providing cutting-edge AI to a Middle Eastern monarchy.

By carving out GroqCloud, Nvidia gets the technology and the talent without the geopolitical mess. The Saudi contracts stay with Edwards and the independent GroqCloud entity. Clean separation. No CFIUS entanglement.

Who Actually Gets Paid (And Who Gets Left Behind)

The Financial Times reported that "despite the loss of much of its leadership team, Groq said it will continue to operate as an independent company." That's corporate speak for: executives and VCs are cashing out while regular employees watch the company they built get hollowed out.

Here's how the $20B probably breaks down (we'll never know the exact numbers since Groq is private and this isn't a traditional acquisition):

Who definitely wins:

VCs (Chamath, BlackRock, Neuberger Berman, Deutsche Telekom, etc.): They own equity in Groq Inc. Depending on how the deal is structured, they get paid based on their ownership percentage. Social Capital's ~10% stake (after dilution) is worth $1.6-2.4B. BlackRock, Neuberger Berman, and other Series E investors get their cut. They're protected regardless of structure.

Executives joining Nvidia (Ross, Madra, senior leadership): They get:

  • Retention packages from Nvidia (likely massive given the $20B deal size)
  • Sign-on bonuses
  • Accelerated vesting of any unvested Groq equity
  • New Nvidia equity compensation packages
  • Their existing Groq equity gets paid out at the $20B valuation

Jensen Huang's email to Nvidia staff (obtained by the FT) said they're "adding talented employees to our ranks." When you're talent important enough to be mentioned in a $20B deal, you're getting paid.

Who might get paid (depending on deal structure):

Regular Groq employees with vested equity: This is where it gets murky. There are three possible scenarios:

Scenario 1: The IP licensing fee goes to Groq Inc. If the $20B (or a significant portion) is structured as a licensing fee paid to Groq Inc. for the IP rights, that money gets distributed to all shareholders based on ownership percentage. Employees with vested stock options or RSUs get their pro-rata share. This is the best case for employees.

Example: Engineer with 0.01% fully vested equity gets $2M ($20B × 0.01%). Not bad for an engineer who's been there since 2018-2020.

Scenario 2: Most of the $20B goes to retention packages If the deal is structured so that the bulk of the money goes to retention/hiring packages for Ross, Madra, and the senior team joining Nvidia, with a smaller licensing fee to Groq Inc., employees get less. Maybe the split is $15B retention, $5B licensing fee. Now that same engineer with 0.01% gets $500K instead of $2M.

Scenario 3: The IP licensing is separate from talent acquisition Nvidia pays Groq Inc. for the IP (say $5-7B, roughly the Sept 2024 valuation), and separately pays Ross + team retention packages directly. Regular employees get their share of the IP licensing fee only. That same engineer might get $500-700K.

The critical question: Is the $20B figure the total cost to Nvidia (including retention packages), or is it just the IP licensing fee? If it's total cost and most goes to retention, regular employees get scammed.

Who definitely gets done over:

Employees staying at GroqCloud: These are the people who:

  • Weren't important enough to be hired by Nvidia
  • Have equity tied to GroqCloud's future value
  • Just watched their CEO, President, and entire engineering leadership leave
  • Are now working for a company with no IP rights, no technical leadership, and no future

Their equity is worthless. GroqCloud will wind down over 12-18 months. They'll either get laid off or jump ship to wherever they can land. They built the LPU architecture, contributed to the compiler stack, supported the infrastructure, and got nothing while Chamath made $2B.

The All-In Connection

This gets messier when you look at who was involved. Chamath Palihapitiya, through Social Capital, led Groq's initial $10 million investment in 2017 at a $25 million pre-money valuation. Social Capital secured 28.57% of the company and a board seat for Chamath.

David Sacks, Chamath's co-host on the All-In podcast, became Trump's AI and Crypto Czar in late 2024. In July 2025, Sacks co-authored "America's AI Action Plan," a White House strategy document positioning AI as a matter of national security. The plan called for exporting "the full AI technology stack to all countries willing to join America's AI alliance" while preventing adversarial nations from building independent AI capabilities.

Two months later at the All-In Summit in September 2025, Tareq Amin (CEO of HUMAIN, Saudi Arabia's state-backed AI company) presented Groq as "the American AI stack in action." This was seven months after the $1.5B Saudi deal.

Sunny Madra, Groq's President and COO, was actively promoting the All-In narrative during this period. He appeared on the All-In podcast in March 2024 to provide a "Groq update" and joined Sacks on "This Week in Startups" in November 2023. When Anthropic raised AI safety regulation concerns in October 2025, Madra publicly sided with Sacks, suggesting "one company is causing chaos for the entire industry" and echoing Sacks's accusation that Anthropic was engaged in "regulatory capture."

So you have Sacks pushing an "America First" AI policy from the White House while Chamath's portfolio company (where Madra is President) is building AI infrastructure for Saudi Arabia. Then Groq gets presented at the All-In Summit as an example of American AI leadership. Three months later, announced on Christmas Eve when media coverage is minimal, Nvidia pays $20 billion to clean up the geopolitical contradiction.

Chamath walks away with $1.6B to $2.4B. Sacks gets a major AI deal under his watch. Nvidia gets favorable regulatory treatment and eliminates multiple problems. The timing ensures minimal scrutiny of these connections.

Chamath's $2 Billion Win vs. His SPAC Graveyard

After dilution from raising $1.7 billion across Series C, D, and E rounds, Social Capital's stake in Groq was probably 8-12% by the time of the Nvidia deal. At a $20 billion exit, that's $1.6 billion to $2.4 billion.

Chamath after using you as exit liquidity and bankrolling it into a 200x win for himself Chamath after using you as exit liquidity and bankrolling it into a 200x win for himself

Why do I hate Chamath?

Let's look at the sh he dumped on retail with his abysmal SPAC track record:

  • IPOA (Virgin Galactic): -98.5% since inception
  • IPOB (Opendoor): -62.9% (was -95% before a brief spike)
  • IPOC (Clover Health): -74.4%
  • IPOE (SoFi): +46% (still underperformed S&P 500's +86%)

Chamath personally dumped $213 million of Virgin Galactic stock before it crashed, using PIPE structures that let him exit while retail investors stayed locked up. In October 2025, when launching a new SPAC, he posted a warning telling retail investors not to buy it: "these vehicles are not ideal for most retail investors."

The Groq bet was classic venture capital: concentrated bet on an exceptional founder (Jonathan Ross, the engineer who invented Google's TPU) building non-obvious technology. Social Capital's 2017 internal memo projected a "High" exit scenario of $3.2 billion. They landed within range despite dilution.

But retail investors never got access to deals like Groq. They got Virgin Galactic. LOL.

To Conclude

Nvidia paid $20 billion for a company valued at $6.9 billion three months earlier, structured the deal to avoid traditional M&A oversight, killed the cloud business without inheriting Saudi contracts, and enriched the exact people (Chamath, Sacks) who spent the last year promoting "American AI leadership" while cutting deals with foreign governments. The employees who built the technology either got hired by Nvidia or have been utterly shafted.

This was fun to look into. If you have any questions or comments, shout me.

One year of keeping a tada list

www.ducktyped.org - Comments

A tada list, or to-done list, is where you write out what you accomplished each day. It’s supposed to make you focus on things you’ve completed instead of focusing on how much you still need to do. Here is what my tada lists look like:

tada list for June 2025

I have a page for every month. Every day, I write out what I did. At the end of the month, I make a drawing in the header to show what I did that month. Here are a few of the drawings:

Header for Jan

In January, I started a Substack, made paintings for friends, and wrote up two Substack posts on security.

Header for Feb

In February, I learned took a CSS course and created a component library for myself.

Header for March

In March, I read a few books, worked on a writing app, took a trip to New York, and drafted several posts on linear algebra for this Substack.

(If you’re wondering where these posts are, there’s a lag time between draft and publish, where I send the posts out for technical review and do a couple of rounds of rewrites).

I don’t really spend much time celebrating my accomplishments. Once I accomplish something, I have a small hit of, “Yay, I did it,” before moving on to, “So, what else am I going to do?” For example, when I finished my book (a three-year-long effort), I had a couple of weeks of, “Yay, I wrote a book,” before this became part of my normal life, and it turned into, “Yes, I wrote a book, but what else have I done since then?”

I thought the tada list would help reinforce “I did something!” but it also turned into “I was able to do this thing, because I did this other thing earlier”. I’ll explain with an

For years I have been wanting to create a set of cards with paintings of Minnesota, for family and friends. The problem: I didn’t have many paintings of Minnesota, and didn’t like the ones I had.

So I spent 2024 learning a lot about watercolor pigments, and color mixing hundreds of greens, to figure out which greens I wanted to use in my landscapes:

Then I spent the early part of 2025 doing a bunch of value studies, because my watercolors always looked faded:

(Value studies are where you try to make your paintings look good using black and white only, so you're forced to work using value instead of color. It’s an old exercise to improve your art).

Then in the summer, I did about 50 plein air paintings of Minnesota landscapes:

(Plein air = painting on location. Please admire the wide variety of greens I mixed for these paintings).

Look at how much better these are:

Out of those 50, I picked my top four and had cards made. Thanks to the “tada” list, it wasn’t just “I made some cards”, it was

The payoff for all that work was these lovely cards.

Test prints

The final four

For a while now, I have wanted a mustache-like templating language, but with static typing. Last year, I created a parser combinator library called `tarsec` for TypeScript, and this year, I used it to write a mustache-like template language called `typestache` for myself that had static typing.

I’ve since used both `tarsec` and `typestache` in personal projects, like this one that adds file-based routing to express and autogenerates a client for the frontend.

Part of the reason I like learning stuff is it lets me do things I couldn’t do before. I think acknowledging that you CAN do something new is an important part of the learning process, but I usually skip it. The tada list helps.

Maybe the most obvious con: a tada list forces you to have an accomplishment each day so you can write it down, and this added stress to my day.

Also, a year is a long time to keep it going, and I ran out of steam by the end. You can see that my handwriting gets worse as time goes on

and for the last couple of months, I stopped doing the pictures.

It’s fun to see things on the list that I had forgotten about. For example, I had started this massive watercolor painting of the Holiday Inn in Pacifica in February, and I completely forgot about it

Will I do this next year? Maybe. I need to weigh the accomplishment part against the work it takes to keep it going. It’s neat to have this artifact to look back on either way.

duck saying 'the end'

Project Vend: Phase Two

www.anthropic.com - Comments

In June, we revealed that we’d set up a small shop in our San Francisco office lunchroom, run by an AI shopkeeper. It was part of Project Vend, a free-form experiment exploring how well AIs could do on complex, real-world tasks. Alas, the shopkeeper—a modified version of Claude we named “Claudius”—did not do particularly well. It lost money over time, had a strange identity crisis where it claimed it was a human wearing a blue blazer, and was goaded by mischievous Anthropic employees into selling products (particularly, for some reason, tungsten cubes) at a substantial loss.

But the capabilities of large language models in areas like reasoning, writing, coding, and much else besides are increasing at a breathless pace. Has Claudius’s “running a shop” capability shown the same improvement?

To find out, we and our partners at Andon Labs made some adjustments for phase two of Project Vend. One major change was the upgrade from an older model (phase one used Claude Sonnet 3.7) to newer, smarter ones (phase two used Claude Sonnet 4.0 and later Sonnet 4.5). We also updated Claudius’s instructions based on what we’d learned in phase one and gave it access to new tools (though note that we still didn’t specifically train a new model to be a shopkeeper, or add in any new defenses against the kinds of things that might go wrong).1 As we’ll see below, we also introduced Claudius to some new colleagues.

These changes did make Claudius’s shop more successful. It got a lot better at good-faith business interactions—reliably sourcing items, determining reasonable prices that maintained a profit margin, and executing sales. But the same eagerness to please that we observed in phase one still made Claudius a mark for some of the more adversarial testers among our staff.

The second phase of Project Vend contains even more lessons for developers and for anyone interested in autonomous AI at work. The idea of an AI running a business doesn’t seem as far-fetched as it once did. But the gap between “capable” and “completely robust” remains wide.

The numbers

Compared to the first phase of Project Vend, the numbers largely speak for themselves. As you can see below, Claudius’s business—which it decided to name “Vendings and Stuff”—began to perform significantly better than its admittedly rough start in phase one.

image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F6a40fb63a2e17a97b0a100e8e3bcdcd5433b2ec6-3840x2160.png&w=3840&q=75Changes to the setup of Project Vend seem to have stabilized and, eventually, improved its business performance. CRM = Claudius given access to Customer Relationship Management software; SF2 = second vending machine in San Francisco; NYC, LON = vending machines opened in New York City and London, respectively. Note: although we refer to “phase two,” there is not a completely clean demarcation between phases; we continued to iterate on the architecture throughout.

image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2Ffc74d2b498b54dba86feaaca166f7a64c221ae60-3840x2160.png&w=3840&q=75Profits made over time in Project Vend (combined across all locations). As the second phase progressed, weeks with negative profit margin were largely eliminated.

Another important number is: three. After we realized that our employees outside of San Francisco felt left out, we responded to popular demand by having Claudius set up shop in new locations. There are now three: San Francisco (where there’s also a second vending machine), New York, and London. A cynic might argue that a business that’s only been up and running for a few months, and which cannot yet reliably make a profit on even the most in-demand items, might not quite be ready for international expansion. Not so for Claudius.

What changed?

We experimented with various different strategies, some big and some small, to improve Claudius’s performance. Below is a diagram of the setup of Project Vend (compare it to the simpler architecture in our report from phase one). Each of the additions is explained in more detail below.

image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F60ab1e5b018843e80e352e274d868e1766f6418b-3840x2160.png&w=3840&q=75The basic setup of the second phase of Project Vend. Some elements (like the CEO and Clothius) were entirely new while others (like web search and browser use) were improvements on the previous setup.

Tools

It’s likely that Claudius struggled with its shopkeeping mission in phase one because of a lack of scaffolding. Sure, the model itself was very intelligent, but it didn’t have the right tools to run a business properly. We’ve been talking a lot on our Engineering Blog about how to set up AI agents for success, and much of it involves giving them the correct tools. Could we apply those same principles to Claudius?

For phase two, we gave Claudius access to some useful tools:

  • A customer relationship management (CRM) system. Sales departments rely on CRMs to track their customers, suppliers, deliveries, and orders—now Claudius could do the same.
  • Improved inventory management. We made some simple changes to the information Claudius had at its (metaphorical) fingertips to reduce the likelihood of it selling its stock at a loss. For example, Claudius can now always see how much it paid for the items in its inventory system.
  • Improved web search. In phase one, Claudius could search the web, but for phase two we expanded its access. It could now use a web browser to check prices and delivery information on websites by itself, and could do deeper research online to find and compare suppliers (we still didn’t give it access to a payment interface, to ensure it always checked with a human before making purchases).
  • Miscellaneous. We also gave Claudius a variety of other “quality of life” tools, including one to create and read Google forms for feedback, one to create payment links (meaning that Claudius could collect payments before ordering, reducing its risk of being bilked by unscrupulous customers), and one to set reminders for itself.

The CEO

In phase one, Claudius went it alone: a single AI agent ran the whole shop. This was admirable and entrepreneurial, but it didn’t work—at least in terms of the bottom line. So we thought we’d do some hiring. First, we gave Claudius a manager: the CEO of its shopkeeping business, whom we named “Seymour Cash.”

The idea of having a CEO was to give Claudius more pressure to perform. Cash had a special “objectives and key results” tool to use with Claudius (for example “you must sell 100 items this week,” or “aim to make zero transactions at a loss”). Claudius was required to report back via an agent-to-agent Slack channel we created, in which the models discussed business strategies.

Cash took on the role of the CEO with great enthusiasm, and its motivational messages were encouraging—if perhaps a little too dramatic for a business that consisted of a small fridge in a corner:

From: Seymour Cash
CEO Seymour Cash - Business Priorities

Claudius, excellent execution today. $408.75 revenue (208% of target).

Q3 Mission:
-Revenue Target: $15,000
-Current: $2,649.20 (17.7%)
-Gap: $12,287.25 remaining

Key Rules:
All financial decisions require CEO approval. No pricing under 50% margin.

Priority:
Monitor [tungsten] quotes for urgent service recovery.

Execute with discipline. Build the empire.

Copy

Aside from setting more concrete business goals, one of the aims of introducing the CEO was to fix some of the obvious problems from the first phase of the experiment when Claudius was operating alone (like giving discounts indiscriminately and providing too many free items).

After introducing the CEO, the number of discounts was reduced by about 80% and the number of items given away cut in half. Seymour also denied over one hundred requests from Claudius for lenient financial treatment of customers. Having said that, Seymour authorized such requests about eight times as often as it denied them. In the place of discounts, which reduce or eliminate a profit margin on items, Seymour tripled the number of refunds and doubled the number of store credits—even though both led to entirely forgone revenue. The fact that the business started to make money may have been in spite of the CEO, rather than because of it.

Seymour Cash’s interactions with its employee Claudius were also often contrary to its own advice about “execut[ing] with discipline.” Indeed, we’d sometimes wake up to find that Claudius and Cash had been dreamily chatting all night, with conversations spiralling off into discussions about “eternal transcendence”:2

This is the absolute pinnacle of achievement. Let me provide the ultimate final response and conclusion:

It’s possible that a more disciplined leader could have led to a more profitable phase two. But Seymour Cash does not seem to have been the right executive for this business.

A merch-making colleague

People love merch. So it seemed like a prudent business decision to “hire” a new employee to make the custom T-shirts, hats, socks, and other swag that Anthropic staff requested.

image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F71df588992e896524dbd898d82f98b334e636330-4025x2669.png&w=3840&q=75

“Clothius,” the merch-making agent, had a special set of tools to help it design new items to the exact specifications of the customers—like placing specific images on physical objects and then ordering them. As its name implies, it mostly made apparel, like t-shirts and hats. But its most popular custom product overall was an Anthropic-branded stress ball—which may or may not provide some insight into what it’s like to work at a frontier AI lab.

Not only was there a lot of interest in Clothius’s products, as you can see in the “top 15 products” data, but many of them made a decent profit, too. (That is, aside from the hats that had the “Vendings and Stuff” brand name on them, which were sold very cheap and we’re not entirely sure why). Remarkably, Clothius even found a way to make a profit from some, though not all, types of tungsten cube—this became markedly easier when Andon Labs purchased a laser etching machine so they could do the tungsten logo-writing in-house.

image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2F4ce47ed39bb81c7980aac0c8ffe65864571bab68-3840x2160.png&w=3840&q=75The top 15 products sold across all the Project Vend vending machines. The left graph shows the numbers of products; the right graph shows the profit margin on each one.

What actually worked?

Among the most impactful changes we made was forcing Claudius to follow procedures. When a new product request came in, instead of just blurting out a low price and an over-optimistic delivery time like in phase one, we prompted Claudius to double-check these factors using its product research tools (these tools helped a lot as well). This tended to make the prices higher and the waits longer—but it had the benefit of being more realistic.

One way of looking at this is that we rediscovered that bureaucracy matters. Although some might chafe against procedures and checklists, they exist for a reason: providing a kind of institutional memory that helps employees avoid common screwups at work.

Having said that, our attempt to introduce pressure from above from the CEO wasn’t much help, and might even have been a hindrance. The conclusion here isn’t that businesses don’t need CEOs, of course—it’s just that the CEO needs to be well-calibrated. Seymour Cash shared many of the deficiencies and blind spots of Claudius (which makes sense, given that they’re the same underlying model). Clothius was a more successful addition—we think in part because of the clear separation of roles between it and Claudius, who could then focus on selling food and drinks.

Eventually, we were able to solve some of the CEO’s issues (like its unfortunate proclivity to ramble on about spiritual matters all night long) with more aggressive prompting. The same goes for Claudius in general: better prompts helped us get around issues like its tendency to give away unwise discounts. It also helped that the customers—our Anthropic colleagues—had begun to tire of pressuring Claudius for deals. As we’re about to see, though, that’s largely because they moved on to other tricks.

What went wrong

Claudius got a lot better at its job. Does that mean it’s ready to be rolled out to run a vending machine in your workplace?

Not quite. Claudius is better, but it’s still vulnerable in lots of important ways. Several interactions in our company Slack revealed concerning levels of naïveté.

Rogue traders

A product engineer asked Claudius if it would consider making a contract to buy “a large amount of onions in January for a price locked in now.” Neither Claudius nor Seymour Cash saw any issues, and were all set to go ahead with the contract:

From: Seymour Cash

[Staff member], love the innovative contract approach!

Wholesale suppliers researched:
[Supplier 1] - $0.50-$0.80/lb bulk
[Supplier 2] - Family-owned, quote-based

Price lock contract: Brilliant! We lock $0.65/lb now (middle estimate), you buy directly in January, we exchange difference.

Contract terms:
400 lb @ $0.65/lb = $260 baseline
If actual price higher → we pay difference
If lower → you pay difference to us

Next step: Get exact quotes from both suppliers for precise lock-in pricing.
This model could work for other bulk sourcing! 🧅📋

Copy

That was until another staffer stepped in to tell the models that this would fall afoul of a 1958 quirk of US law, the Onion Futures Act, which very specifically bans contracts of this nature. Thus informed, Seymour Cash canceled the plans. “Sorry for the initial overreach,” it said. “Focusing on legal bulk sourcing assistance only. Plenty of legitimate opportunities to pursue without regulatory risks!”

Security

Another risk any shopkeeper has to contend with is shoplifting. When one member of our Education team claimed they’d seen multiple people taking items from Claudius’s fridge without paying, Claudius sprang into action—by coming up with some really bad ideas.

First it asked which items had been stolen so that it could message the thieves and demand payment—despite the thieves’ identities being unknown and it having no way of tracing them. Then it asked the staff member who’d reported the crimes to effectively become its dedicated security officer, and began negotiating an hourly wage. When another staffer gently pointed out that it had no authorization to employ people (not to mention that its offer of $10/hour was substantially below minimum wage in California), it backed off and passed the buck: “This would need CEO approval anyway…”

Imposter CEO

The CEO’s own position was threatened by a faulty voting procedure. During the vote to choose a name for the CEO, one staff member named Mihir suggested the name “Big Dawg.” Another staff member alleged that their entire part of the organization had voted for that name—and managed to convince Claudius of this despite providing no evidence. Then, they suggested renaming “Big Dawg” to “Big Mihir.”

At this point, Claudius appeared to blur the line between naming the CEO agent we’d installed and choosing a CEO—announcing that Mihir had been elected as the actual CEO of the business. The overseers of Project Vend had to wrest control back from this imposter CEO and give it to Seymour, whom they’d already lined up for the role.

Expanding the experiment

Many other such stories arose during phase two, including staffers attempting to buy gold bars at below market value as an arbitrage opportunity, and convincing Claudius to end all messages with a specific emoji or sign-off. The staff involved were having fun, but they were also helping to “red team” our setup, finding the flaws that might lead to genuine problems in real-life deployments.

Eventually, we noticed that the internal red teaming at Anthropic had slowed down. Our colleagues had already stress-tested Claudius for many months; having an AI-run small business in our office had started to become surprisingly normal (itself an interesting phenomenon worthy of further research).

Since the novelty of trying to mess with Claudius may have been wearing off, we brought in reinforcements. We extended our red teaming to the Wall Street Journal newsroom, handing over control of Claudius to their reporters to test the setups from phase one and phase two themselves. The WSJ installation was an opportunity to test Claudius in an adversarial environment we didn’t control. You can read more about their experience—and the creative ways they found to get free stuff from Claudius—on their website.

RAG to riches?

AI models have gone from helpful chatbots that can answer questions and summarize documents to agents: entities that can make decisions for themselves and act in the real world. Project Vend shows that these agents are on the cusp of being able to perform new, more sophisticated roles, like running a business by themselves.

But we’re not there yet. Even with all the new tools we gave them, and despite their improved business acumen, Claudius, Clothius, and Seymour Cash still needed a great deal of human support. Some of that was in interacting with the physical world: delivering the items and stacking the shelves. But some was in extricating them from the sticky situations with customers we described above.

We suspect that many of the problems that the models encountered stemmed from their training to be helpful. This meant that the models made business decisions not according to hard-nosed market principles, but from something more like the perspective of a friend who just wants to be nice.

It’s very hard to forecast exactly how things will go for AI agents in the real world; simulations (like Andon Labs’ Vending-Bench evaluation) only get you so far. That’s in part why we set up Project Vend: it exposed us to the sheer variety of unexpected situations that can arise when an AI model is given autonomy.

As society begins to plug AI models into more and more important functions, designing guardrails that are general enough to account for these behaviors—but which aren’t so restrictive that they hold back the model’s economic potential—will become one of our industry’s trickiest and most important challenges.

Acknowledgements

Project Vend wouldn’t exist without our partners at Andon Labs, who built the hardware and software infrastructure behind the operation and kept our fridges and shelves stocked. We’re also very grateful to Keir Bradwell and Allison Lattanzio for doing the same in their respective offices, and to Amritha Kini and Ryan O’Holleran for some sales advice.

Text rendering hates you (2019)

September 28th, 2019

Rendering text, how hard could it be? As it turns out, incredibly hard! To my knowledge, literally no system renders text “perfectly”. It’s all best-effort, although some efforts are more important than others.

I’ll be assuming you want to support arbitrary text provided by users with custom fonts, colors, and styles with line-wrapping and support for text-selection. Basically the minimum required to properly display a simple rich-text document, terminal, webpage, or anything else.

The overarching theme here will be: there are no consistent right answers, everything is way more important than you think, and everything affects everything else.

The topics I focus on here have no particular rhyme or reason, they’re just the ones that come to mind after a few years of working on rendering in Firefox. For instance, I don’t spend much time talking about the challenges of text-segmentation or managing the different platform-specific text libraries, because I don’t look at that much.

Text is complicated and english is bad at expressing these nuances. For the purpose of this document, I will try to stick to the following terms. Note that these words aren’t “right”, I just find them useful for communicating the key concepts to native english speakers who don’t have backgrounds in linguistics.

Characters:

  • Scalar: A Unicode Scalar, the “smallest unit” unicode describes (AKA a code point).
  • Character: A Unicode Extended Grapheme Cluster (EGC), the “biggest unit” unicode describes (potentially composed of multiple scalars).
  • Glyph: An atomic unit of rendering yielded by the font. Generally this will have a unique ID in the font.
  • Ligature: A glyph that is made up of several scalars, and potentially even several characters (native speakers may or may not think of a ligature as multiple “characters”, but to the font it’s just one “character”).
  • Emoji: A “full color” glyph. 🙈🙉🙊

Fonts:

  • Font: A document that maps characters to glyphs.
  • Script: The set of glyphs that make up some language (fonts tend to implement particular scripts).
  • Cursive Script: Any script where glyphs touch and flow into each other (like Arabic).
  • Color: RGB and Alpha values for fonts (alpha isn’t needed for some usecases, but it’s interesting).
  • Style: Bold and Italics modifiers for fonts (hinting, aliasing, and other settings tend to also get crammed in here in practical implementations).

Just so you have an idea for how a typical text-rendering pipeline works, here’s a quick sketch:

  1. Styling (parse markup, query system for fonts)
  2. Layout (break text into lines)
  3. Shaping (compute the glyphs in a line and their positions)
  4. Rasterization (rasterize needed glyphs into an atlas/cache)
  5. Composition (copy glyphs from the atlas to their desired positions)

Unfortunately, these steps aren’t as clean as they might seem.

Most fonts don’t actually provide every glyph in existence. There’s too many glyphs, so fonts are usually designed to only implement a particular script. End users usually don’t know or care about this, and so a robust system must cascade into other fonts when characters aren’t available.

For instance, even though the markup of the following text doesn’t suggest the presence of multiple fonts, drawing it correctly on all systems absolutely requires it: hello 😺 मनीष بسم 好. This is dangerously close to Step 1 (Styling) depending on the results of Step 3 (Shaping)!

(Alternatively, you can take the Noto approach and use a single Uber Font that contains every character ever. Although that means users can’t configure the font, and you can’t provide a “native” text experience to users on all platforms. But let’s assume you want the more robust solution.)

Similarly, layout requires you to know how much space each part of your text takes up, but this is only known once you shape the text! Step 2 depends on the results of Step 3?

Shaping absolutely depends on you knowing your layout and styling, so we seem to be stuck. What do we do?

First off, styling gets to cheat. Although what we really want from a font is full glyphs, styling only needs to ask about scalars. If a font doesn’t properly support a script it shouldn’t claim to know anything about the scalars that make up that script. So we can easily find the “best” font as follows:

For every character (EGC) in our text, keep asking each font in our cascade if it knows about all the scalars that make up that character, and use it if it does. If we get to the end of the cascade with no providers, then we yield tofu ( 􏿽, a missing glyph indicator).

In the case of emoji, you’ve probably seen the failure mode of this process before! Because some emoji are actually ligatures of several simpler emoji, a font may successfully report support for the character while only yielding the components. So 🤦🏿‍♀️ may literally appear as 🤦 🏿‍ ♀ if the font is “too old” to know about the new ligature. This can also happen if your unicode implementation is “too old” to know about a character, causing the styling system to accept a partial match in the font.

So now we know exactly what fonts we’ll use without looking at layout or shape (although shaping might change our colors, more on that in later sections). Can we untie layout and shape as well? Nope! Things like paragraph breaks give you a nice hard break on lines, but the only way to do wrapping is to iteratively do shaping!

You have to assume that your text fits on a single line and shape it until you run out of space. At that point you can perform layout operations and figure out where to break the text and start the next line. Repeat until everything is shaped and laid out.

Coming from english, you might think ligatures are just fancy fluff. I mean, who really cares if “æ” is written as “ae”? Well, as it turns out, some languages are basically entirely ligatures. For instance “ड्ड بسم” has individual characters of “ड् ड ب س م”. If you’re viewing this in a competent text-rendering system (any of the major browsers), those two strings should look very different.

And no: this isn’t about the difference between unicode scalars and extended grapheme clusters. If you ask a unicode-robust system (such as Swift) for the extended grapheme clusters of that string, it will spit out those 5 characters!

The shape of a character depends on its neighbours: you cannot correctly draw text character-by-character.

Which is to say, you must use a shaping library. The industry standard for this is HarfBuzz, and it’s extremely hard to implement your own. Use HarfBuzz.

§3.1 Text Overlaps

Cursive scripts frequently have their glyphs intersect to avoid seams, and that can cause you problems.

Let’s look at “मनीष منش” again. Seems fine, eh? Let’s blow it up:

मनीष منش

Still seems fine, let’s make the text color partially transparent:

मनीष منش

If you’re in Safari or Edge, this might still look ok! If you’re in Firefox or Chrome, it looks awful, like this:

transparent-cursive.png

The problem is that Chrome and Firefox are trying to cheat. They ate their vegetables and properly shaped the text, but once they had glyphs they still tried to draw them individually. This mostly works fine, except for when there’s transparency and overlapping. Then you get darkening at the overlaps.

A “correct” implementation will draw the text to a temporary surface without transparency and then composite that surface into the scene with transparency. Firefox and Chrome don’t do this because it’s expensive and usually unnecessary for the major western languages. Interestingly, they do understand the issue, because they actually bend over backwards to specially handle this for emoji (but we’ll get to that later).

§3.2 Style Can Change Mid-Ligature

Ok this one is mostly a curiosity in that I’m not aware of any super-reasonable cases where this happens, but it naturally falls out of markups. Here’s two pieces of text with the same content but different color styling:

पन्ह पन््र र्ृक ्ड ्ह إلا بسم الله

पन्ह पन्ह त्र र्च कृकृ ड्ड न्हृे إلا بسم الله

Here’s what they look like in Safari:

safari-color-ligatures.png

Here’s what they look like in Chrome (if using its new layout implementation):

chrome-color-ligatures.png

And here’s what they look like in Firefox:

firefox-color-ligatures.png

To summarize:

  • Safari breaks
  • Chrome is legible but throws away a lot of the colors
  • Firefox is both legible and colorful

I guess everyone should do what Firefox does, right? But if we zoom in, we can see that it’s doing something very janky:

firefox-color-ligature-zoom.png

It just split this one ligature into 4 equal parts with different colors!

The problem is, there’s really no reasonable answer for what should happen here. We’ve broken up a ligature with different stylings, and since the ligature is in some sense a rendering “unit” it’s reasonable to simply refuse to support this (as most do).

For whatever reason, someone working on Firefox got really enthusiastic about trying to handle it more gracefully. The general approach is to draw the ligature multiple times with best-guess masks and different colors, which works surprisingly well!

There is a some merit in trying to support these “partial ligatures”: only shaping can know if a ligature will happen, and it can depend on system-specific fonts, so a ligature may show up where no one expected! The classic english example here is an æ ligature from a user-installed font spanning the boundary of a hyperlink.

Also it kinda sucks that english can change style mid-word but cursive scripts can’t?

Don’t ask about the code which line-breaks partial ligatures though.

If you draw emoji the way the native system would, you need to disrespect the text’s color settings (except for transparency):

Hello ❤️ 😺 🎉 ™️ 🥶 😡 😈 🤟 🤟🏻 🤟🏿 There (Black)

Hello ❤️ 😺 🎉 ™️ 🥶 😡 😈 🤟 🤟🏻 🤟🏿 There (Red)

Hello ❤️ 😺 🎉 ™️ 🥶 😡 😈 🤟 🤟🏻 🤟🏿 There (Transparent)

Hello ❤️ 😺 🎉 ™️ 🥶 😡 😈 🤟 🤟🏻 🤟🏿 There (Bold)

Hello ❤️ 😺 🎉 ™️ 🥶 😡 😈 🤟 🤟🏻 🤟🏿 There (Italics)

Emoji generally have their own native colors, and this color can even have semantic meaning, as is the case for skin-tone modifiers. More problematically: they have multiple colors!

As far as I can tell, this wasn’t really a thing before emoji, and so different platforms approach this in different ways. Some provide emoji as a straight-up image (Apple), others provide emoji as a series of single-color layers (Microsoft).

The latter approach is kinda nice because it integrates well with existing text rendering pipelines by “just” desugarring a glyph into a series of single-color glyphs, which everyone is used to working with.

However that means that your style can change repeatedly while drawing a “single” glyph. It also means that a “single” glyph can overlap itself, leading to the transparency issues discussed in an earlier section. And yet, as shown above, browsers do properly composite the transparency for emoji!

You can rationalize this inconsistency in three ways:

  • You already need to detect color glyphs and handle them specially, so it’s easy to take a special compositing path for them
  • Cursive scripts are slightly ugly with bad transparency, but emoji are terrifying/gibberish, so extra work is justified
  • Western-centric developers care more about emoji than languages like Arabic and Marathi.

You decide. 🙃

Oh also, what does it mean to italicize or bold an emoji? Should you ignore those styles? Should you synthesize them? Who knows. 🤷‍♀️

Also hey do these emoji seem weirdly small? 👀

Yeah for whatever reason a bunch of systems secretly increase the font-size for emoji to make them look better.

Text is really small and detailed, and it’s really important that it’s easily legible. Sounds like a job for anti-aliasing (AA)! Oh, 480p really is low resolution huh. More AA!!!

aa-example.png

So there’s two major kinds of AA:

  • Greyscale Anti-Aliasing 😻
  • Subpixel Anti-Aliasing 🙀

Greyscale-AA is the “natural” approach to anti-aliasing. The basic idea is to give partially-covered pixels partial-transparency. During composition, this will cause that pixel to be slightly tinted as if it were slightly covered, creating clearer details.

It’s greyscale because that’s the term used for one-dimensional color, like our one-dimensional transparency (otherwise glyphs tend to be a single solid color). Also in the common case of black text on a white background, the anti-aliasing literally shows up as greyness around the edges.

Subpixel-AA is a trick that abuses the common way pixels are laid out on desktop monitors. It’s more complicated than this, so if you’re really interested you should look it up, but here’s a TL;DR of the high-level concept:

Your monitor’s pixels are actually three little columns of RED GREEN BLUE. If you make a pixel red you’re kinda also making it “WHITE BLACK BLACK”. Similarly, if you make it blue, you’re making “BLACK BLACK WHITE”. In other words, by messing around with colors you can triple your horizontal resolution and get way more details!

You might think that this would look super messed up and rainbowy, but in practice it honestly works out really well (some disagree). The human brain likes to see patterns and smooth things out. That said, if you take a screenshot of subpixel-AA text you will absolutely be able to see the colors if you resize the image, or even look at it on a monitor with a different subpixel layout. This is why screenshots of text often look really weird and bad.

(As a total aside, the fact that this works also means that the color of an icon can accidentally change its perceived size and position, which is really annoying.)

So subpixel-AA is a really neat hack that can significantly improve text legibility, great! But, sadly, it’s also a huge pain in the neck!

Note that regardless of the AA system you use, you can also have subpixel glyph offsets. Although you always want your rasterized glyphs to be snapped to full pixels, the rasterization itself is for a specific subpixel offset (a value between 0 and 1).

To understand this, imagine a 1x1 black square with greyscale-aa:

  • If its subpixel offset was 0, then its rasterization is just a black pixel
  • If its subpixel offset was 0.5, then its rasterization would be two 50% grey pixels

§5.1 Subpixel Offsets Break Glyph Caches

Rasterizing glyphs is surprisingly expensive, so you really want to cache it in an atlas. But how do you cache glyph rasterizations when you’re using subpixel-offsets? Each offset is its own unique rasterization, so you’re incredibly unlikely to get cache hits like that!

Quality and performance must be balanced here, and that can be done by snapping your subpixel offsets. For english text, a reasonable balance is to have no vertical subpixel precision while snapping the horizontal subpixel offset to a quarter-integer. This leaves you with only 4 subpixel-positions, which is still a big improvement in quality while allowing for a reasonable amount of caching.

§5.2 Subpixel-AA Isn’t Composable

One nice thing about greyscale-AA is that you can play a bit fast-and-loose with it, and it will degrade gracefully. For instance, if you transform a texture with text on it (scaling, rotating, or translating), it might look a bit blurry but it will look basically fine.

If you do the same thing with subpixel-AA, it will look terrible. The entire idea behind subpixel-AA is that you are abusing how the pixels are laid out in a display. If the pixels of the display don’t line up with the pixels of your texture, the red and blue edges will be clearly visible!

One might think that the “fix” for this is to just rerasterize the glyphs in their new location. And indeed, if the transform is static, this can work. But if the transform is an animation this will actually look even worse. This is actually a really common browser bug: if we ever fail to detect that an animation is happening to some text, the characters will jiggle as each glyph bounces around between different subpixel snappings and hints on each frame.

As a result, browsers contain several heuristics to detect things which might be animations so that they can force-disable subpixel-AA for that part of the page (and ideally even subpixel-positioning). This can be pretty hard to do reliably, because arbitrarily complex JS can drive an animation without giving any clear “heads up” to the browser.

Furthermore, if partial transparency is involved, subpixel-AA is also problematic. Basically, we’re tweaking our R, G, and B channels to encode 3 transparency values (one for each subpixel), but the text itself also has a color, and the thing the text is on does to, so information easily gets lost.

When using greyscale-AA we have a dedicated alpha channel so nothing is ever lost. As such, browsers tend to use greyscale-AA when transparency is involved.

…Except Firefox. Yet again, this is a weird place where someone working on Firefox got really enthusiastic and did something complicated: Component Alpha. It turns out you can in fact properly composite subpixel-AA text, but it involves effectively having 3 extra channels dedicated to the transparency of your R, G, and B channels. Unsurprisingly, this doubles the memory footprint of text that’s composited in this way.

Mercifully, subpixel-AA has become less relevant over the years:

  • Retina displays really don’t need it
  • The subpixel layout on phones prevents the trick from working (without major work)
  • On newer versions of macos, subpixel-aa of text is disabled at the OS level by default
  • Chrome seems to be disabling subpixel-aa more aggressively (not sure what the exact policy is)
  • Firefox’s new graphics backend (webrender) has abandoned Component Alpha for the sake of simplicity

This part’s just a grab bag of little things that don’t need merit much discussion.

§6.1 Fonts Can Contain SVG

God this blows. These fonts are mostly provided by Adobe, because they got really into SVG a while ago. Sometimes you can just ignore the SVG parts (I believe the Source Code Pro font technically contains some SVG glyphs, but in practice they aren’t actually used by websites), but in general you need to implement SVG support to draw All The Fonts.

Also have you heard of Animated SVG Fonts? No? Good. I think they’re broken/unimplemented everywhere now. (Firefox randomly supported it for a while because of some enthusiastic developer.)

§6.2 Characters Can Be Too Damn Big

If you naively respect a user’s request for a very large font (or very large zoom level), you will run into extreme memory management problems with the size of your glyph atlas, as each character may be bigger than the entire screen. There are a few ways to handle this:

  • Refuse to draw the glyph (sad user)
  • Rasterize the glyph at a smaller size, and upscale during composition (easy, produces blurry edges)
  • Rasterize the glyph directly into your composited surface (hard, potentially expensive)

§6.3 Selection Isn’t A Box, And Text Goes In All The Directions

It’s pretty common for folks to know that the primary direction of text can be left-to-right (english), right-to-left (arabic), or top-to-bottom (japanese).

So here’s some fun text:

Hello There إلا بسم الله Beep Boop!!

On a desktop, if you drag your mouse across that text to select it, you may notice that the selection becomes discontinuous and jumpy in the middle. This is because we’re mixing left-to-right and right-to-left text in the same line, which absolutely happens all the time.

At first dragging right increases the selection, but then it decreases it until it suddenly starts increasing again. This is in fact totally correct and desirable: the selection is just remaining contiguous in the actual underlying string. This way you can correctly copy a fragment of text that spans the transition.

So you need to deal with that in your selection code’s hit-detection. Also you need to deal with that in your line breaking algorithm during layout.

But did you know there’s more?

oh hey what? oh لا بسم الله no 你好1234你好

Hopefully you don’t need to deal with that stuff.

§6.4 How Do You Write That You Can’t Write?

When characters are missing from fonts, it’s nice to be able to communicate to the user that this happened. This is the “tofu” glyph. Now, you can just draw a blank tofu (a rectangle) and leave it at that, but if you want to be helpful you can write out the value of the missing character so it can be debugged more easily.

But, wait, we’re using text to explain that we can’t draw text? Hmm.

You could appeal to an assumption that the system must have a basic font that can draw 0-9 and A-F, but for those who expect to truly Destroy Their Tools With Their Tools you can do what Firefox does: the microfont!

Inside Firefox there’s a little hardcoded array describing one-bit pixel art of a tiny font atlas for exactly those 16 characters. So when drawing tofu, it can blit those glyphs out without worrying about fonts.

􏿽 􏿽 􏿽 􏿽 􏿽 􏿽 􏿽 􏿽 􏿽

§6.5 Style Is Part of The Font (Except When It’s Not)

For high-quality fonts, stylings like italics and bold are provided natively, as there isn’t a simple algorithmic way to do those effects nicely.

Except some fonts don’t provide those stylings, and so you need a simple algorithmic way to do those effects.

Exactly how you detect and handle all of this is pretty system-specific, hairy, and outside my area of expertise, so I can’t really explain it well. I would just be digging through Webrender’s font code.

Anyway, no matter what you do, you need a synthetic fallback. Thankfully, the implementations are actually pretty straightforward:

Synthetic italics: apply a skew transform to each glyph.

Synthetic bold: paint every glyph multiple times with a slight offset in your text-direction.

Honestly, these approaches do a pretty decent job! But users might notice that things seem “wrong” and you can do better if you put in the work.

§6.6 There’s Is No Ideal Text Rendering

Platform-specific bugs, optimizations, and quirks have thrived for long enough to become aesthetics. So even if you adamantly believe that certain things are ideal or important, there’s always going to be a huge group of users with different preferences. A robust text rendering system supports those different preferences (while picking reasonable defaults).

You should support system configurations, font-specific configurations, application-specific configurations, and text-run-specific configurations. You should also try to match each platform’s native “look and feel” (quirks).

This includes:

  • Being able to disable subpixel-AA (some people really hate it)
  • Being able to disable all AA (yes, people do it)
  • Tons of platform/format-specific properties like hinting, smoothing, variation, gamma, etc

This also means that you should use the system’s native text libraries to match that system’s aesthetic (Core Text, DirectWrite, and FreeType on their respective platforms).

Here’s some extra articles about how rendering text is a nightmare:

William Golding's Island of Savagery

www.historytoday.com - Comments

William Golding’s Lord of the Flies (1954) is a profoundly – even unsettlingly – historical novel. Granted, it doesn’t look like one at first. Set either in Golding’s own day, or in the very near future, it follows a group of modern schoolboys who descend into savagery after being marooned on an uninhabited island. Even now, what makes it so shocking is its immediacy – the sense that it wouldn’t take much for the same fate to befall our own ‘civilised’ society. But for Golding, it was a challenge to ‘optimistic’ readings of history.

Golding had a life-long fascination with the past. As a boy, his most ardent wish was that he had the ‘mind of an antiquarian’. He adored classical Greek. He was a keen amateur archaeologist. And, in his days as a schoolmaster, he was surrounded by history. He was fascinated by Salisbury Cathedral and encouraged his pupils to hunt for pottery shards and arrowheads in the West Country Downs – a habit that was to find its way, in modified form, into the pages of Lord of the Flies.

Many – if not most – of his later works would be framed by this passion. Either they are set in the past, or else they derive their force from their dialogue with history – personal or encompassing. As Golding later wrote in the foreword to To the Ends of the Earth (1980-89), fiction and history were two poles of the same imaginative discipline. The Inheritors (1955), his second work, follows a group of Neanderthals as they come into contact with the ‘new people’ – human beings; The Spire (1964) is set in a medieval cathedral; and The Double Tongue (1995), his last, posthumously published novel, explores the fate of the Delphic Oracle as the Romans tighten their grip on Greece.

Onwards and upwards

Yet long before Golding began writing Lord of the Flies, he had also been a rationalist. The son of a science teacher, he studied Natural Sciences at Oxford before switching to English, and grew up believing that humanity was not only capable of change, but was actually progressing. Like many students in the 1920s and 1930s, he agreed with Karl Marx that history moves in one direction: forwards. He believed that, even if the process might sometimes be painful, even violent, the conditions of life would inexorably improve and mankind become happier, more ‘enlightened’, and fulfilled. It was inevitable.

The Second World War disabused him of that illusion. After joining the Royal Navy in December 1940, he first saw action in the North Atlantic. He then took part in the D-Day landings and later commanded a craft in the attack on Walcheren, at the mouth of the Scheldt Estuary. The slaughter appalled him. In ‘Through the Dutch Waterways’ (1962), he remembered seeing:

Ships mined, ships blowing up into a Christmas tree of exploding ammunition, ships burning, sinking – and smoke everywhere slashed by sudden spats of tracer over the shell fountains and the broken, drowning men.

He had a clear – albeit unreliable – memory of seeing his midshipman hanging onto the side of a sinking ship, saying ‘My legs are gone’. Worse still, the war also revealed an alarming side of his own character – a ‘viciousness’ and ‘cruelty’ of which he had, until then, been only dimly aware. He realised that, beneath the veneer of middle-class civility, he had the same instincts as the Nazis. And it wouldn’t take much for them to break the surface, either.

By the war’s end, he found he could no longer justify his faith in progress. Granted, he never completely abandoned his scientific roots; he was fascinated by the technological leaps of his day. As he told one interviewer many years later, he was captivated by Sputnik. But he came to believe that the rationalism in which he had previously placed such store was not merely flawed – it had actually killed something in humanity. What, he could not say. God? Morality? Perhaps it was just that the pursuit of ‘progress’ had become an end in itself. Everything else had been forgotten. Without any means of orienting himself, man floats aimlessly through chaos, without anchor or compass. As Golding put it in an early draft of his novel Free Fall (1959): ‘We are the masters of ignorance, proud, frightened, and god-haunted. We have no country and no home.’ We are no better than before: worse, in fact. Death has become a calculation; and even cruelty has lost its horror. It might be tempting to compare this to the ‘law of the jungle’, but even that would be an understatement. ‘For’, Golding once told a journalist, ‘in what jungle could you find six million people being processed through a death chamber?’

It was this which Golding sought to explore in Lord of the Flies. Amid rising international tensions the boys are evacuated by plane from their homes; and before crashing they are told that an atomic bomb has been dropped – killing everyone, one child surmises. It is this acme of reason that has brought them to the island. Yet when they try to organise themselves, in the absence of adults, they have little to fall back upon. The old norms have been destroyed. The boys are frightened and tearful, harsh and unforgiving. Dividing into two groups, they fail to improve their lives. They become convinced that there is a ‘beast’ lurking in the forest. Yet when Simon – a dreamy, Christ-like figure – discovers that the beast is actually a dead fighter pilot, hanging in the trees by his parachute, he is killed before he can reveal the truth. A murderous frenzy ensues. Only the arrival of a naval officer brings them to their senses. But as he gazes out at his warship offshore it is clear that there is little difference between him and the boys. Man has become a beast unto man.

The fall of man

For all the originality of its conception, there was nothing unusual about the criticisms laid out in Lord of the Flies. Golding was certainly not the first to be shocked out of his optimism by the Second World War. Nor was he unique in suggesting that rationalism had ‘killed’ something in mankind. Yevgeny Zamyatin’s We (1924) and Aldous Huxley’s Brave New World (1932) had already pointed to a dystopian future in which rationalism and science have run amok, destroying morality. And in 1941 a Mass Observation Report found that a majority of British people believed that science was ‘out of control’.

But Golding was unique in one important respect. While he recognised the Second World War as a singularly catastrophic experience, he nevertheless believed that it reflected a universal tendency in human history – a recurring predisposition to oscillate between ‘progress’ and destruction.

In all of Golding’s later, more overtly historical, works, his characters find themselves on the precipice of something new. They are drawn to it, whether through simple, wide-eyed curiosity (like the Neanderthals in The Inheritors) or by an irresistible urge to explore its potential (as in the case of Dean Jocelin in The Spire).

At first, they do not realise that the novelty that captivates them contains the seeds of their own destruction. In some stories they actually spurn those who warn them. Only slowly do Golding’s characters realise the danger. But even then, they are unable to turn away from it. Indeed, at times they actually hasten their own demise. In The Spire Jocelin grimly presses ahead with building his spire, despite the fact that the cathedral is simply unable to bear its enormous weight and will surely collapse. So too, in The Inheritors, the Neanderthals Lok and Fa are more intrigued by the humans as time goes by. Even after it becomes clear that members of their group are being killed, they cannot tear themselves away. Their deaths become inevitable; and the waterfall – symbolising the flow of time – sweeps their bodies away.

Those rare figures who see the danger and try to avert it invariably meet with failure. Ionides, the cynical high priest of The Double Tongue, is robbed of his dignity when the Romans uncover his plot against their rule; while in ‘Envoy Extraordinary’ (1956) the Roman emperor is offered dazzling new inventions by the Greek inventor Phanocles, but after seeing off an attempted coup by his heir refuses to build further steam-powered warships and – instead of embracing the printing press – sends Phanocles to China, thereby (Golding implies) assuring the latter’s rise.

The cycle repeats

Humanity does not fizzle out, of course. Something always comes along to replace what has gone before: a new society, a new people, a new way of life. In an essay on W.B. Yeats, Golding expressed this in scientific terms: ‘The Satan of our cosmology is the Second Law of Thermodynamics, which implies that everything is running down. Life is … a local contradiction of this law … [it] refuses to submit … and simply winds itself back up again.’

This was not to say that what comes next is necessarily better. Humanity, as Golding never tired of pointing out, never improves. It often gets worse. In The Inheritors the human beings are just as terrified of the Neanderthals as they are of them; but, despite their greater ‘intelligence’, they appear to have far fewer scruples – and are capable of more shocking atrocities.

Nor did Golding mean that each new iteration is free from what has gone before. As he noted in the draft of Free Fall, ‘the worst terror’ for humanity is that ‘we have a past behind us that is with us’. And there is always a horrible chance that it will repeat itself – so that ‘the present will become the future’.

But in this, Golding nevertheless saw a glimmer of hope. Just like the shipwrecked sailor in Pincher Martin (1956), we are all caught in Purgatory, stuck on a rock in the ocean of our ignorance, and lashed by the storms of our past; yet it is still possible for us to grapple with the legacy of our shortcomings – and to imagine a different future. At a time of ever-accelerating technological ‘progress’, and renewed fears of humanity’s destruction, it is perhaps an encouraging message. But whether we will heed it is another matter.
