The person who did the cover design for my book has her own website where you can see her beautiful art and graphic design work. http://www.annamacijeski.com/
Dig deep. This blog contains good performance and testing insights in every year. Some of it is serious, some of it is big-picture, and then there is this: An Atari-class, music video on the wonderfulness of testing with music by group They Might be Giants.
A lot of my readers are from India. Since it is always good to support the home team, I’d like to point out there is a CMG India site http://www.cmgindia.org/ with some good performance links and information you might find valuable.
If you are doing any performance work on web sites, you should read Steve Souders’ book. It is beautifully written, and wildly useful.
He also has a blog at: http://www.stevesouders.com/blog/
This site has much to offer those interested in computer performance work. The person who runs it is remarkably dedicated to making good information available and is also a very nice person. Full disclosure: I have contributed content to the site.
