fork() is evil; vfork() is goodness; afork() would be better; clone() is stupid

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

Creating a redis Module in 15 lines of code!

A quick guide to write a very very simple "ECHO" style module to redis and load it. It's not really useful of course, but the idea is to illustrate how little boilerplate it takes.

Step 1: open your favorite editor and write/paste the following code in a file called module.c

#include "redismodule.h"
/* ECHO <string> - Echo back a string sent from the client */
int EchoCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {

O(n!) solution to the n-Queen puzzle (https://en.wikipedia.org/wiki/Eight_queens_puzzle)
/**
* Solves the n-Queen puzzle in O(n!)
* Let p[r] be the column of the queen on the rth row (must be exactly 1 queen per row)
* There also must be exactly 1 queen per column and hence p must be a permuation of (0 until n)
* There must be n distinct (col + diag) and n distinct (col - diag) for each queen (else bishop attacks)
* @return returns a Iterator of solutions
* Each solution is an array p of length n such that p[i] is the column of the queen on the ith row
