I'm know following more great repos from various but take a look of the two repos I'm in love with at the moment
fish - the friendly interactive shell
fish is a smart and user-friendly command line shell for OS X, Linux, and the rest of the family. fish includes features like syntax highlighting, autosuggest-as-you-type, and fancy tab completions that just work, with no configuration required.
Factory Girl in PHP
factorygirl is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user, adminuser, and so on), including factory inheritance.
