I've written a few books over the years on technical/security topics. In addition, a bunch of friends of the RenderLab have written books as well and deserve mention.
The links below go to the page at Amazon.com. I get a small percentage of the purchase price (about 4%) which is plowed right back into the RenderLab research and site budget. Hey, if you were going to buy it anyways, why not support the author?
