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.

17 Feb 2020 : Shower Gel or Soap: which is best? #
Apparently humans do their best thinking in the shower. When I'm in the shower I wonder mostly about whether I should be using soap or shower gel. The good news is, there's a clear answer. Check out my blog post on the topic to find out.
15 Feb 2020 : Waste data dump #
The fortnight before last was exceptional, but I didn't do too badly this week either. My latest waste data stats show my daily output to be 149g over the last week. That's still well below my 300g target. The reason for the increase from last week was mainly due to newspapers.
9 Feb 2020 : Waste data dump #
It seems this was a super-successful week for my waste budget. In fact, I skipped my trip to the bins last weekend because they weren't full enough to make it worthwhile. So my average over the last fortnight was 87g a day, well below my 300g target. That brings my average for this year down to 200g per day. Not every week is going to be like this, but it does show that with a bit of planning and individul will it's possible to bring the amount of waste we produce down. In particular, I'm avoiding tins and glass and doing my best not to throw out any out-of-date food. It's strange to think that just by creating myself arbitrary goals it's altered my willingness to eat older food. I'm so easily to manipulate, I can even do it to myself.

Another waste data dump. Overall output was 1563g (averaging 224g per day), which is up on last week, but still well below my 300g aim.
