March 14, 2011 by alex

And I give you… The Disemvoweler! Shorten your text and easily tweet the results.

Motivation, and predicting the future.

March 10, 2011 by alex

Which one is that, again?

Creating a bonded network interface in Red Hat linux

February 3, 2011 by alex

Simple handling of 1 or many method arguments

January 21, 2011 by alex
