Web emulator for DCPU-16
0x10co.deThis one is a 1700+ line operating system (AtlasOS, a multi-process capable DCPU-16 Operating System):
just amazing. The code is apparently available at https://github.com/Noxer/AtlasOS.
Things like this make me feel so stupid. :(
One of the cool things about the website is the ease of forking snippets.
When the Word of Notch gave information on how input would work, previous code written using alternative schemes broke.
The snake game, http://0x10co.de/cdbk1, was one of these programs. However, it wasn't too long before people started hacking on it and started forking the code. Here's a version at the bottom of the fork tree:
One draw back is that the newer versions don't show up on the top programs page (since people find out about the original first, and the fixes later) and give the illusion that website doesn't work properly.
(Not to get too meta, but..) I really like the domain name. It looked like "0x10 code" when I first saw it.
That's the point. https://en.wikipedia.org/wiki/Domain_hack
This website http://domai.nr help finding such domain names.
I was going to suggest that you add a quick reference, but then I saw that it was on the right. It would be cool if the quick reference had stuff about the [addr] and :jmplabel and PC crash use, but other than that I am highly impressed with this site!
Great work on the web emulator!
So--and forgive my ignorance here--is there actually a spec up for things like hardware interrupts, IDTs, trap vectors, whatever?
This all seems of limited utility until we know how the machine is actually structured.
This is the only spec that we have to work with: http://0x10c.com/doc/dcpu-16.txt . Notch said he's reviewed quite a bit of feedback on the spec and to expect revisions although it may be a while.
The rest of our information comes from Notch's tweets. Interrupts are unlikely. IO is memory mapped. There's been some guessing about display and keyboard but nothing set in stone.
In addition to the official spec, there are twitter posts and sample code, which is currently being taken as spec. Colors were justified based on an early screenshot that had text coloring.
Here's Notch's code, originally linked to on twitter, that has been used to justify the way the 16 word buffer works in 0x10co.de
There are, officially, no interrupts. As for the other bits I'm doubting it but Notch hasn't said anything official.
shameless self promotion: i also wrote a dcpu emulator pastebin at http://dcpubin.com/ as a weekend exercise to learn heroku and mongodb. it's definitely not as pretty as 0x10code, though. i've also decided not to implement some features (like keyboard input) until an official spec is released for them. maybe that's the wrong choice, not sure. anyway, it's a fun project to hack on. the code is here: https://github.com/jazzychad/dcpubin
It would be really cool if there was a link to the spec[1], some examples or a tutorial with this.

As I see most of sketches are related to printing on screen ;)
I had to send the author some Bitcoins; he made it feel like the most natural thing in the world!
Feature request: ability to vote up
Views counter is not very useful really: sketches from top are getting more views, random view is adding chaos. Voting up would be very good tool to identify interesting programs.
Also, the founder is an 18-year-old that applied for ycombinator. Hi.
At this point, I'm just waiting for people to start releasing games centered around the DCPU-16 before Notch even releases his.
Is it open source, I mean, are others free to use it in their games?
neat. I took a look at the code base and there is a number of files with a jade extension. Anybody know what language/framework that is?
I've gotta say, it's my first ever experience with express, jade, or a web app on Node (I've done decent amounts of non-web Node stuff, though). When I was starting ti get 10 requests per second, I still wasn't even caching anything.
Jade - robust, elegant, feature rich template engine for nodejs: https://github.com/visionmedia/jade
Ugh, what a crappy description. What about "Jade: Haml-style, indentation-based, interpolation template engine for Node.js"?

Node.js. Express. Jade. MongoDB.
This is actually quite entertaining :)
The debugger is great! Until this came along I was really struggling to figure out how to write any kind of code for this DCPU thing. I don't have a background in assembly or really any sort of low level programming. The debugger makes the code a lot more approachable for someone like me!
However running stuff in it locks up the browser a little bit. I will definitely improve on that, but I'm glad it is at least useful.
