It is worth noting this whole series is incredible. I used to work with the guy who started it (@jordansissel), and he was an incredible sysadmin/software engineer. If you go through the archives on the right side, you will find lots more incredible posts (although he doesn't write them all anymore, they are all of excellent quality).

Seconded! It goes back two years, and hopefully will continue for many more. Excellent series.

Agreed, all of these articles are really well-written.
