One of my side projects is a little tool called Noisemaker. NoiseMaker is a utility that runs in the background and generates white noise over the computer's speakers to mask out distractions like the TV, phone, annoying co-workers, etc... If you need it, you need it badly...
It's available as a shareware program at Icegiant Software
One interest of mine is programming languages, and more specifically, Lisp and Scheme. Lately, the blogosphere has produced a couple interesting blogs that tie to this interest:
Planet Lisp aggregates a bunch of Lisp-related blogs, while LtU is more general and more of a discussion site.
Related, I came to LtU via Eric Lippert's Blog over on Weblogs @ASP.Net. Eric is a developer at Microsoft who's done a lot of work on Windows scripting and the Windows script languages.
