I just listened to an interesting interview on Hanselminutes with Owen Rogers, one of the original developers of CCNet. They discussed continuous integration and continuous monitoring. Well worth a listen.

During the interview Scott and Owen mentioned a few technologies/products I hadn't heard of yet. One is Gumstix, which are super-micro Linux computers, literally the size of a stick of chewing gum. Another is Chumby a wifi-connected open Linux platform alarm clock on steroids. Some very cool stuff that I definitely need to learn more about (and of course will eventually succumb to purchasing).
