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.

30 Apr 2022 : Waste data dump #
For logistical reasons, it's just a week since my last waste data dump. But now there's fresh data on the waste page. My daily waste average this week was 166.83 g, which is actually rather high. I'm not sure why that is, but compost is the only category that's noticeably high, so I have a suspicion it's a consequence of broccoli.

I'm a bit more back on track with my waste output this last fortnight, with the data just uploaded to my waste page. Last time my average daily output jumped to 270.50 g/day, but now it's back down to 137.93 g/day, which is only very marginally higher than my 2022 average of 136.64 g/day. Everything was pretty normal apart from my waste paper output, which was up slightly. Unfortunately this is still a fair bit higher than my 2021 average of 119.88 g, so I still need to work on getting it down.
11 Apr 2022 : Waste data dump #
A little late, but I've just uploaded another two weeks of data to my waste page. It wasn't a great week waste-wise, mostly a combination of Joanna visiting (more people) and my birthday (wrapping!). Which means that almost everything was up (general, compost, card and paper). My daily average over the fortnight was 270.50 g/day, double my 2022 average up to this point of of 136.44 g/day. I'll have to try to rebalance that in future periods.

My latest waste data is now uploaded to the site. The numbers are up on the last set of values, but only because I was away for half of the previous period. My waste output for the last fortnight has actually been pretty average, just a slight reduction in card and paper compared to normal.
13 Mar 2022 : Waste data dump #
My latest waste data has been added to the waste page. I spent a week away from home, wich has brought down my average. On top of that I also spent a few days working in the office rather than at hoe, which likely brought it down even further. As a result I reached a very low 68.50 g/day, taking my average so far for 2022 to 116.87 g/day. Partitioning the data into waste types, I was also down across all categories except for returnables. As it gets warmer, I'm likely to buy more soft drinks, so this is the start of my returnables increasing.
