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.

Ooops, a little late, but it's still Bonfire Weekend, if not Bonfire Night, so now there are fireworks on the site too. Pop, bang, fizzle, ziiiip.
6 Nov 2021 : Waste data dump #
I've added another portion of data to my waste page. Over the last fortnight my overall average was 176.21 g/day of waste, which is a chunk more than my 2021 average of 123.95 g/day. I experienced a big spike in general waste (mostly because I disposed of a broken electric toothbrush). Everything else was also slightly up, but not markedly so, so it's mostly down to that toothbrush I think!

I need to sort out a proper ghost-like shader as a Halloween background, but it'll have to wait for a future year. In the meantime, here are some creepy blinking eyes instead. They're watching you!

My latest waste data dump has gone up on my waste page. This was a bit of a long period of 18 days, maybe because I spent three of them in Berlin, but my waste output was also down. Averaging 96.94 g/day, which is much lower than my current 2021 average of 121.47 g/day. Everything was down except paper, for some reason. I've also been spending more time in work, so fewer lunches at home. Maybe that makes a difference too?

Another batch of waste data is now up on my waste page. I bought a leak, which always seems to get split half-half between dinner and the bin with all of its excess foliage, alongside some rolls that sadly went mouldy, means there was a blip in my compost waste this period. The other categories were all about average for 2021. The result is that my daily average of 142.19 g/day is slightly higher than my 2021 average of 123.06 g/day. I'll need to buy more efficient vegetables from now on.
