A good post on regular expressions. Just in case you ever wondered if they were actually useful.

Icon fonts can be a really useful tool in lightweight web design. These sets are a pretty good place to start with a lot of commonly useful pictographs.
RegexMatch
A really good (and good-looking) regular expression tester for OS X. Handles groups, sub-matches, substitutions and exporting regular expressions in a variety of languages.
completeme 0.2.5
A very cool filename completion tool for quickly opening a file in your editor from the command line. Via OneThingWell.
