IRL Name: 
Jon Hall

Jon "maddog" Hall is a programmer and GNU advocate who was instrumental in obtaining equipment and resources for Linus Torvalds to accomplish his first port, to Digital's Alpha platform when he was still in Digital. It was also in this general timeframe that Hall, who lives in New Hampshire, started the Greater New Hampshire Linux Users' Group. Hall has UNIX as his New Hampshire vanity license plate.


At the UK Linux and Open Source Awards 2006, Hall was honoured with a Lifetime Recognition Award for his services to the open source community.

The nickname "maddog" was given to him by his students at Hartford State Technical College, where he was the Department Head of Computer Science.

In June 2012, in honor of Alan Turing, Hall published an article in Linux Magazine announcing that he is gay.

He is regarded as one of the earliest Linux hackers.
