Ice Cube: Ruby Date Recurrence Library - Andrew W
https://github.com/seejohnrun/ice_cube
If you've ever had to deal with repeating events in Ruby then you've probably had to bend your mind around all the complicated date/time maths. Throw multiple timezones in for good measure and then you'll soon be needing some aspirin and a lie down in a dark room. To the rescue is the Ice Cube library which deals with all the complicated stuff for you, has a nice fluent API for adding rules and can handle serializing to both YAML and ICAL for persisting rules to a database.

After our developer tips and tricks event yesterday I found myself looking
through the bash manual reading about .inputrc - turns out it's the
config for readline, the library bash uses for reading input. While
reading this I also found set -o vi which makes the bash prompt editing
of the current command behave a little bit like vim. This needs to be in
.bashrc but it also works in readline.zsh for those using zsh.
