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.

19 Jun 2022 : Waste data dump #
Time for my fortnightly-ish waste data dump again. The latest numbers have been added to the waste page. This fortnight I somehow managed to keep my waste output relatively low: 106.47 g/day on average, lower than my current average for 2022 of 135.62 g/day, There were no big standout values in the category, most of which were around average or below. So I'm not really sure how I managed to be more frugal than usual. Maybe being back in the office means lower lunch-related waste?
3 Jun 2022 : Waste data dump #
Another waste data dump to the waste page, this time covering two periods (I forgot to upload the last set of data at the time, but it doesn't actually affect the graphs or data at all). In this last period there's a bit of an uptick in general and paper waste. The former, I suppose, because Joanna was visiting for part of the period, and the latter, I expect, because I recycled all of the notes from my Finnish class that took place during the first half of the year. Quite a lot of notes, as it turns out. Overall my latest daily average is a bit too high at 148.94 g. I'll need to work quite hard if my daily average for 2022 (currently at 138.88g) is to come down below my daily average for 2021 (119.88g). I might even need to figure out some kind of strategy.
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.
