DVI vs. VGA
I have been using dual screens with my PowerBook, which has a Digital Video Interface (DVI) rather than VGA (whatever that stands for) the the external display. Doing a very quick A/B I did not see a huge difference between the two. Having one less adapter in my life is a Good Thing ™ so I always try to use DVI. I finally got around to Googling the difference and what I found is: DVI is best for LCD's and the like, VGA is best for tubes. At least according to that guy. But he sure sounds like he knows what he is talking about.
It is sort of cool that our display technology has developed to the point that your display is showing you an exact copy of the digital information. CRT's are soon to be a thing of the past.

Here Comes the Video
Apple is including a built-in iSight camera in their new computers. These days, when Apple thinks its important, it's probably important. I just got an iSight and it does kind of get your wheels turnings in regards to the uses of real-time video chat or webcam-style video. This is in addition to the obviously growing utlization of online video e.g. vlogs and traditional tv-style content. If video conferencing was super-duper easy, we'd all do it. Thus, we will all do it. It's coming. Comb your hair.

Video: Geek Stoplight
Subscribe in iTunes | Watch Quicktime
That's right folks... TechEvangelists is videoblogging! We aim to document and explore whatever tickles our tech-art fancy, including interviews with both under-the-radar tinkerers and your favorite Web 2.0 luminaries. For our debut video, we turned inward to our own Matt Gray (bio | blog). He bought an old stoplight on eBay and, out of sheer boredom, decided he wanted to control it with a computer. A party machine is born.
Matt promises to provide a step-by-step outline after the holidays, including schematics and the script controlling how the stoplight responds to music input.
