Jordi Gutiérrez Hermoso is a coder, mathematician, and hacker-errant. He has run Debian GNU/Linux exclusively since 2002, both at home and at work. Jordi is involved with GNU Octave, a free numerical computing environment largely compatible with Matlab, and with Mercurial, a distributed version-control system. He enjoys pure and applied mathematics, skating, swimming, and knitting. Lately he’s been thinking a lot about greenhouse gas emissions and rhino conservation efforts.
