Show HN: ram-dl – A tool to download more RAM written in Go
github.comHi HN! I've built ram-dl, a tool that allows you to upload and download RAM to/from your system. Run `ram-ul` to upload RAM, and `ram-dl` to download it. Well, sort of :P
It works like this:
1. Starting a go-nbd server and client locally with r3map's Device API
2. Connecting the NBD server to a remote fRPC[1] backend provided by ram-ul
3. Calling mkswap, swapon and swapoff, which enables paging out to the block device provided by the NBD client and thus to the connected remote fRPC backend.
Its mostly intended as a tech demo for go-nbd[2] and the WIP r3map[3] library (efficient distributed mmap with mounting and migration support), and just as a fun experiment in general.
