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.

16 May 2018 : GetiPlay update v0.2-6 #
The latest GetiPlay for Sailfish OS phones is now up on OpenRepos. This update has the latest get-iplayer (v3.14, which is always one of the most exciting version numbers to hit!) and I'm hoping will get the perl dependencies right (after literally years of trying). The code is on github.

9 May 2018 : Moving on #
Since I'm no longer an RA at the Computer Lab, I've updated my info to better reflect reality. No fake news here. I'm still in Cambridge, just not doing the same thing.

16 Apr 2018 : Publications spring clean #
There's no doubt we're well into spring now, so time for some cleaning. I'ved added three more publications. Two still in press, but the third available for download on Seamless Authentication with Pico. I'd say more about it, but I think it's probably obvious from the title. If not, it's only a one-pager.

7 Jan 2018 : Undeck the halls #
There were Christmas snowflakes on the site, and there was even some real snow in the meantime, but now Epiphany has passed and the decoractions have come down. The site now has Inigo Quilez's beautiful bokeh effect as its shader-generated animated background again.
