Creating new stuff isn’t easy. Meticulous and beautiful designs don’t just happen by accident. Computer programs don’t write themselves. However, some scientists (like Richard Dawkins) theorize that DNA wrote itself. So, if you follow that theory, you can Twine your PC to some random Twitter feeds, go to the beach all afternoon, and when you get back, your new Ruby on Rails program will have written itself. Try explaining that one to your boss. Or better yet, find some VCs who will invest in it. (The only catch is that they might have to wait billions and billions of years for the ROI). That plan might work for you… but for programmers looking for some good advice today, you might want to check out StackOverflow.com (a new advice service for programmers) — from Joel Spolsky and Jeff Atwood.
