Seldom without a computer of some sort since graduating from the University of British Columbia in 1978, I have been a full-time Linux user since 2005, a full-time Solaris and SunOS user from 1986 through 2005, and UNIX System V user before that.
Aside from that, I spend a considerable amount of time writing proposals, technical reports and - of course - stuff on https://www.opensource.com.
Thank you Aleksandra! As a fellow mathematician (though I fear a somewhat lapsed one), I always enjoy seeing this kind of illumination of mathematical concepts with relevant concrete examples. Great article!
Josip! What an awesome article, thank you very much for the clear explanation and demos and the site... wow!
