Server Sponsors
I am being sponsored by Syntress since 2007! They bought me an amazing dedicated server to run catonmat on. If you're looking web services in Chicago area, I highly recommend the Syntress guys!
My Amazon Wish List
I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my

1. Can you write a short shell to find any IPV4 IP addresses in any files under /var/lib/*. Perform a dns reverse. Lookup for each IP found, and format the output neatly, like “IP=192.168.0.1, hostname=jo.blogg.com. http://jo.blog.com“?
