This is the homepage of Martin Tournoij, also known as Carpetsmoker and arp242 on the web. I write about stuff on this page, occasionally.

I currently work as a software developer to pay my bills; I consider myself fairly lucky, since this is what I actually enjoy doing. I currently use Ruby (on Rails) with CoffeeScript; in previous bill-paying endeavours, I used PHP, Python, and JavaScript. I’ve also programmed in C, Scheme, Haskell, and Perl. I like to use FreeBSD or OpenBSD, and I’ve used Linux a lot as well. In general, I feel UNIX is the way to go.

I play the guitar & bass guitar, both after a fashion. I like all sorts of music

For code projects, see my BitBucket page; I also have some stuff over at GitHub. I can also be found on StackOverflow, the FreeBSD Forums, DaemonForums, RationalWiki, and a number of other places. You can email me at
