Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

A simple shell script to quickly / easily install "pacaur" on archlinux
#!/bin/sh
#
# !!! IMPORTANT !!!
# As of 2017-12-14, pacaur is unmaintained (https://bbs.archlinux.org/viewtopic.php?pid=1755144#p1755144)
# For alternatives see the arch wiki: https://wiki.archlinux.org/index.php/AUR_helpers#Active
# pacaur seems to get occasional updates to fix breaking changes due to pacman updates though.
#
# If you are new to arch, I encourage you to at least read and understand what
# this script does befor blindley running it.
# That's why I didn't make a one-liner out of it so you have an easier time

An example of using pthread's condition variables, showing how to block a main thread while waiting for worker threads to finish their work, without joining the threads. This could be useful if you want to loop the threads, for example.
#include <pthread.h>
#include <stdio.h>
#include <unistd.h>
#include <assert.h>
/* Compile like this:
gcc --std=c99 -lpthread cond.c -o cond
