Welcome

I'm David Llewellyn-Jones and this is my homepage. I'm a software engineer at Jolla, who's also interested in programming, security, privacy and graphics. I occasionally crave adventure and a good thunderstorm. You might be interested in my software, my research 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.

10 Jun 2019 : All the taste without the tracking #
Even though I've used Disqus for the comments on this site for aaaages now, it's always been a bit of a sore point. Not only does it slow down page loads, but even more seriously it allows Disqus to track users visiting my site, and I abhor tracking. So thanks to Michał Szczepaniak for spurring me into action, I've finally come up with a solution I can live with. Instead of loading the Disqus code automatically, you now have to hit a button at the bottom of the page to load the comments (take a look at this post for an example). Until you do that, Disqus can't track you, and page loading will be super fast. When I get time I'll do a proper comparison of the benefits and post it to my blog.

2 Jun 2019 : Pedalo... delayed Sailfish OS addition #
Back last year when I released Pedalo, a privacy-preserving app for measuring your relative cycling performance for Sailfish OS, I somehow forgot to add the download info. I've now added it to the Pedalo page.

22 Mar 2019 : What does the latest petition tell us about changing attitudes to Brexit? #
With the latest petition trying to revoke article 50 and block Brexit, I've crunched the numbers again to find out how the mood is changing in different parts of the UK. Check out my regrexitmap to see which parts of the UK are movig more towards remain, and which are moving more towards Brexit. And if you're surprised by the result, you should also check out the map I generated in May 2016 using data from a similar petition which attracted over 4 million signatures three years ago. The astonishing thing is that compared to back then, very little... very very little has changed.

It's ephiphany, so the Christmas decorations have come down. No more snow on this page, even though here in Tampere we've been having snow storms and everything exposed to the sky is covered in a thick layer of the suff.
