I just came to move some ruby scripts onto my mac mini, and to do so I needed to install a couple of gems. Now I realised I hadn't installed or updated rubygems on the machine for a while, so I figured it was best to update gem before installing the gems I wanted. Easier said than done.

When I create a rails app from scratch I like to include certain plugins to help me write the app, such as the Rspec testing framework instead of the built-in Test::Unit and jQuery instead of prototype.

To search your php.ini file quickly and easily with the option to use regular expressions, I tend to drop back to the cli. The reason for this is I can easily parse the output of phpinfo() with grep, and can do various things with the output, could even pass it to a script if I really wanted to.
