Mac helpers

Some Mac-related things that have helped with the day-to-day:

• UTC clock widget - detailed instructions here.  UTC is way easier to work with as a base for date/time normalization, but it's a pain to constantly have to convert in your head (especially if you travel).  Modifying the World Clock widget was simple.  Remember to look in /Library not /Library and make a backup just in case...
• iTunes control - you control: tunes.  I use all of my Spaces and with this free utility I get iTunes music control no matter which Space I'm in (adds controls to your menu bar).
