I’m not really a programmer, but I do use bash/ruby and occasionally go to write things to make my life a bit simpler.
iptabl.es - A site for quickly generating iptables rules.
doodle-client - A gem to vote on doodle polls.
p.zy.io - A small password generating site that’s pretty convenient when used with curl.
Keyboard firmware - Absolute frankenstein of some other firmwares, munged together and edited to give my keyboard NKRO functionality.
strava.zy.io - A work in progress site to mess around with your strava statistics.
Shoplift patcher - Not too relevant now, but this chunk of bash was an automatic patcher for the spectacular magento shoplift vulnerability.
I also contribute to various opensource projects when I’m able to.
