Systems administrator and programmer living in New Zealand.
Please email me if you’d like a listing of work experience including my current employer.
I maintain a blog called Arabesque, with posts mostly about Unix command line tools.
Its byline is
Systems, Tools, and Terminal Science.
There are reader translations and e-book compilations of many of the articles around the web.
Posts have featured in magazines such as BSD Magazine and the now-defunct Hacker Monthly.
