Gary Porteous is a Professional Security Researcher based in the UK and a keen advocate of open source projects. A hacker in the old sense of the word, as someone who creatively dissects and reconstructs technology, Gary feels both at home tinkering with small finite problem solving as considering the pattern of modern technology and it's larger implications. Having been involved with Macintosh security since 1998, more recently he has worked as a systems engineer and consultant, and is currently employed as a Macintosh computer expert in the UK educational sector. Alongside all this he enjoys escaping to the countryside whenever possible and helping to run the organization AppleseedUK (www.appleseeduk.org).
