I consider myself a hacker: “Hackers are individuals who come up with novel, complex, simple or elegant ways of writing new software that restates or replaces the existing constraints thereby exposing either some new functionality or some of the original flexibility of the underlying machine.“ Many examples of recent hacks can be found on my blog. The two hacks I’m the most proud of are my Remote-controlled air conditioning, and the more recent Greyhole: Easily expandable & redundant storage pool using Samba.
