DNA seen through the eyes of a coder

This has been around a while, but I just found it. Explanation by a gentleman named Bert Hubert about the similarities between genetics and computer systems, with the analogy of DNA to source code as a focal point. A very cool read: DNA seen through the eyes of a coder. It seems to have been written 9 years ago (in 2002), and I'm no molecular biologist, but I think there have been some interesting advanced in epigenetics since then. I wonder how that fits into the analogy?
