The only way to learn a new programming language is by writing programs in it.

UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.

A program designed for inputs from people is usually stressed beyond breaking point by computer-generated inputs.

A new release of Plan 9 happened in June, and at about the same time a new release of the Inferno system, which began here, was announced by Vita Nuova.

For books, I don't read much fiction, but like travel essays and good pop-science.

I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time. I'm a home-body and get fatigued by it fairly soon, but enjoy thinking back on experiences when I've returned and then often wish I'd arranged a longer stay in the somewhat exotic place.

I listen to mostly-classical music, but mostly by radio - I'm not an audiophile.
