Scrabulizer is a Scrabble Solver. Enter your tiles and it will give you the highest scoring moves. I co-develop, support and maintain the Scrabulizer website, iPhone app and browser extensions.
TZInfo is an open-source time zone library I developed for the Ruby language. It allows developers to build applications that include conversions between times in different time zones. The popular Ruby on Rails web application framework uses TZInfo for its time zone support.
