Welcome
I'm David Llewellyn-Jones, a Research Data Scientist for The Alan Turing Institute at the British Library in London. I occasionally crave adventure and a good thunderstorm.
I'm interested in programming, privacy, maths and graphics. I'm a proponent of open source, open research, and end-users' right to privacy and control. I strive to contribute to a circular economy.
This site has been capturing my thoughts and outputs on these topics since 1998, including my software, research and 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.

14 Mar 2025 : Fixing armTex and TeXFonts downloads #
Thanks to the impressively astute Chris Dewhurst from Drag N Drop, who noticed not only the broken links but also the capitalisation required to fix them, I've now updated the download links for armTeX and TeXFonts on the RISC OS page. The links have been broken for almost exactly five years now, which I only know because it was on 17 March 2020 that the site moved from a Windows server to a Linux server. As you may know, Windows ignores the capitalisation of filenames whereas Linux is very particular about it. Hence the broken links. I should have noticed sooner, but I'm happy to finally be able to say the issue is fixed thanks to Chris's diligence.
9 Mar 2025 : NewPipe dev diary #
Today I started a new project — a NewPipe-dev dary — which will chart my progress as I attempt to build a YouTube client based on NewPipe for Sailfish OS. The first preamble post is now up.
3 Mar 2025 : Comments using Mastodon #
The site now supports comments using Mastodon, replacing the old Disqus integration. I've been hoping to find a replacement for over thirteen years now, so it feels mighty good to finally move on!
1 Mar 2025 : Flagellum update #
I've updated Flagellum, the code that runs this site, so it now supports light/dark themes and Open Graph metadata out-of-the-box. This site was already using the functionality, so this is just bringing the repo up to speed.
28 Jan 2025 : FOSDEM'25 slides #
I've added the slides for my FOSDEM'25 talk "Mobile Browsers: the Best of Times, the Worst of Times" to the presentations page.
