You must have Systemd version >= 240 for this to work. Check with systemd-analyze --version. If not... that sucks I guess? I don't know of a way to upgrade without horribly breaking everything.

[git-annex][1]

git-annex allows managing files with git, without checking the file contents into git. While that may seem paradoxical, it is useful when dealing with files larger than git can currently easily handle, whether due to limitations in memory, time, or disk space.

Crafting a Compiler from Scratch: Implementation Notes

For the past two weeks or so, I've been working on a little compiler project in C, mostly for educational purposes, i.e. to understand how a compiler really works. I'm not using any libraries, other than the C runtime library.

Introduction

I have a hand-written lexer and parser, and a simple code generator targetting

	def old_style_coroutine():
	yield from asyncio.sleep(1)

	async def main():
	await old_style_coroutine()

	/*
	Copy this into the console of any web page that is interactive and doesn't
	do hard reloads. You will hear your DOM changes as different pitches of
	audio.

	I have found this interesting for debugging, but also fun to hear web pages
	render like UIs do in movies.
