Art & Craft

June 24, 2008 By JimK Leave a Comment

Two friends and I went on a photo trip a few months ago. We went to the Owens Valley to make landscapes. None of us is an accomplished landscape photographer.  Our motivation was to have a good time together doing something we like to do. Still, we were serious about it.

[This post is unabashedly technical, and contains nothing that you absolutely need to be a good photographer. I couldn’t help myself.] You’d have to be living in a cave to miss the big switch in personal computing from a single processor per chip to two or four, with eight coming soon. The power dissipation of… [Read More]
