a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Bash: Sudo keep-alive (good for long-running scripts that need sudo internally but shouldn't be run with sudo)
#!/bin/bash
# Might as well ask for password up-front, right?
sudo -v
# Keep-alive: update existing sudo time stamp if set, otherwise do nothing.
while true; do sudo -n true; sleep 60; kill -0 "$$" || exit; done 2>/dev/null &
# Example: do stuff over the next 30+ mins that requires sudo here or there.

Use this when Amazon gives you an "Encoded authorization failure message" and you need to turn it into something readable. If you only get a request id... you're out of luck.
function decode-authorization-failure-message {
if [ $# -ne 1 ] || [ "$1" = -h ] || [ "$1" = --help ]; then
cat <<'EOT'
Usage: decode-authorization-failure-message <message>
