Welcome

I'm David Llewellyn-Jones and this is my homepage. I'm a researcher in computer security who's also interested in programming and graphics. You might be interested in my research, my software or my random musings.

Want to know more about me? Here's a personality sketch written by a psychologist when I was in school.

“David is of high intelligence, although lacking in true creativity. He has a need for order and clarity, and for neat and tidy systems in which every detail finds its appropriate place. His writing is rather dull and mechanical, occasionally enlivened by somewhat corny puns and by flashes of imagination of the sci-fi type. He has a strong drive for competence. He seems to have little feel and little sympathy for other people and does not enjoy interacting with others. Self-centered, he nonetheless has a deep moral sense.”

Wow. Harsh. But disturbingly accurate.

27 Feb 2016 : Moving to fixed-width after 18 years #
Today I switched the site to a fixed-width template. It wasn't easy, and I wrote a blog post about it so you can share my pain. Click the 'Full width' button on the homepage to go back to how it was before.
