I'm an old open-source independent hacker,
concerned about concepts of ethical hacking, teaching and sharing.
I like to play with shell, perl, lisp (sometime), sed and lot of other languages/environments.
Co-system administrator in several configurations, after various SMEs, I like to sometimes take time to focus on methods that I can improve or re-create (for example to change the level of abstraction).
In this, surfing on differents StackExchange's sites is a good way to boost my inspiration!
