I recently happened upon a very interesting implementation of popen() (different API, same idea) called popen-noshell using clone(2), and so I opened an issue requesting use of vfork(2) or posix_spawn() for portability. It turns out that on Linux there's an important advantage to using clone(2). I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.

This is not a paper. I assume reader familiarity with fork() in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou

A guide to ANSI on Discord

Discord is now slowly rolling out the ability to send colored messages within code blocks. It uses the ANSI color codes, so if you've tried to print colored text in your terminal or console with Python or other languages then it will be easy for you.

Quick Explanation

To be able to send a colored text, you need to use the ansi language for your code block and provide a prefix of this format before writing your text:

\u001b[{format};{color}m

	BIN = ./node_modules/.bin
	SRC = $(wildcard src/*.coffee)
	LIB = $(SRC:src/%.coffee=lib/%.js)

	build: $(LIB)

	lib/%.js: src/%.coffee
	@mkdir -p $(@D)
	@$(BIN)/coffee -bcp $< > $@

	#include <stdlib.h>
	#include <unistd.h>
	#include <string.h>
	#include <stdio.h>
	#include <stdint.h>
	#include <stddef.h>
	#include <signal.h>
	#include <limits.h>
	#include <errno.h>
	#include <pthread.h>
