An example of a parallel work scheduling system using only the Rust standard library
// Here is an extremely simple version of work scheduling for multiple
// processors.
//
// The Problem:
// We have a lot of numbers that need to be math'ed. Doing this on one
// CPU core is slow. We have 4 CPU cores. We would thus like to use those
// cores to do math, because it will be a little less slow (ideally
// 4 times faster actually).
//
// The Solution:

On macOS: Install pygmentize and alias pcat for shell code syntax highlighting
# first install pygmentize to the mac OS X or macOS system with the built-in python
sudo easy_install Pygments
# then add alias to your ~/.bash_profile or ~/.bashrc or ~/.zshrc etc.
alias pcat='pygmentize -f terminal256 -O style=native -g'

Docker cheat sheet

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

  • One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
  • A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

  • Unison for file synchronization
  • EncFS for folder encryption

# Script for installing tmux on systems where you don't have root access.
# tmux will be installed in $HOME/local/bin.
# It's assumed that wget and a C/C++ compiler are installed.
# exit on error
set -e
# create our directories
