Something is very wrong when it feels refreshing to enter the appartment, which has 29°, because outside it has 40°.

German #Perl Workshop 2027 in Hanover - 14.04.2027-16.04.2027
Today I learned about `ncdu -x /`, which will show the disk usage on '/', but excludes dirs mounted on other file systems.
Today I braincoded some short SQL fixup while letting the LLM also generate a fix. The LLM was a tiny bit faster (I'd guess it took 60sec vs 90sec on my side), but I liked my solution more. I used a CTE to generate the fixed data and then did an update on select, while the LLM used a subselect.
Favourite quote from https://curtispoe.org/articles/watching-claude-sonnet-outperform-opus: "This is AI, after all. Read the code. If you don’t, “human in the loop” becomes “human in the noose.”"
Today I join an illustrious group of #Perl hackers at the Perl Toolchain Summit in Vienna. I'm mainly here as a local organizer, but I also plan to discuss and hack on a few things, eg containerizing `pause`.

#potd Endless Wellness @ Donauinselfest https://domm.plix.at/potd/2026-07-04.html
Today we had 4 border checks (depart from Senegal, enter Gambia, cross the Gambia river on the ferry, exit Gambia and enter Senegal) and had to deal with two foreign currencys (at least one payment for the "transit visa" when entering Gambia felt a bit shady). A big "THANK YOU" to the EU as we don't have to suffer through this when travelling in Europe!
Today I learned about LEAD() in Postgres Window Functions, which returns the row after the current row in a partition of data. Very handy! #Postgres

Today I spend nearly 13 hours and ~1600km on two trains to get from Berlin via Strasbourg to Marseille. It worked like a charm, was rather comfortable (due to me sitting in first class) and not that expensive (212€).

Live Demo from German Perl Workshop, what could possible go wrong?
Today I had to reimport some data because the online spreadsheet that the data was entered in interpreted a URL ending with a UUID as a number and increased the value in each row (if the UUID happend to end with a digit and the human operator "dragged" the rows down to copy the values). Thanks for nothing, "smart spreadsheet". Please stay dumb and don't fiddle with my data!

Today we had our family birthday party for the not so small number of relatives having their birthday in february. My mother made me a box containing one small present for each of my years, each with a picture of me at the respective age. Very beautiful present!
Today I also finished setup of my travel laptop (an old Lenovo Yoga) for our three week journey to Senegal, which starts tomorrow.

Yesterday I explained my mixed feelings regarding LLMs to a friend by comparing them to cars ("I don't like cars, they destroy a lot, but they are also so very convenient"). Today I read the same argument here: https://aphyr.com/posts/420-the-future-of-everything-is-lies-i-guess-where-do-we-go-from-here
#potd A week ago I was cycling over sandy piste in Senegal, now this. After de-icing the bike cycling to the office worked quite well, because the city of Vienna is very good at removing snow from bike paths and streets. The pavements are in a worse state, because removing the snow there is the job of each house owner. https://domm.plix.at/potd/2026-02-20.html
Today I wanted to go scuba diving, but the dive school cancled on me :-( Instead we walked to the most western point of the African mainland and spend a nice afternoon at the beach.
Today I learned how to set up Sway / Wayland with an projector in clone mode for giving a presentation using `wl-mirror` and `wl-present`. This post helped a lot: https://tedn.life/2025/03/09/ubuntu-wayland-sway-just-mirror-the-screen/ . Also better to test/learn this now then right before my upcoming talk at the German Perl Workshop: https://act.yapc.eu/gpw2026/talk/8035

@gugod It's a env.js file that reads environment vars from the env and makes them available to a JavaScript SPA. I guess that's why my mind was set on ENV vars and not JS syntax...
Today I brought down a website by missing a comma in a config file (I thought it was just bash-like env var list, but in fact it was javascript...)

@DrHyde Thanks, pinning works! That's a good enough fix for now (so I can go back to my unregularly scheduled fixing of mail servers being blocked...)

@orangeacme@fosstodon.org Actually I'm welcoming the "5" at the start today. And Happy Birthday to you, too #PerlTwin

@gregoa_ I did encounter those controls on various train rides, and while they do suck, are sort-of-illegal and totally pointless (because you can just cross the Austrian/Germany border by bike and nobody bothers if you bring a squad of Taliban along), the process between Gambia and Senegal is a bit more involved (including taking fingerprints with hardly working machines, a few questions and several opportunities to shorten the process by inserting some small bank notes...)
The current snowfall and 0° in Vienna is a rather hard slap in the face compared to the sunshine and 25°+ we had the last weeks in Senegal.

#potd Fat Freddy's Drop @ Arena, open air, family outing; great gig playing Based On A True Story (and some more, including a Happy-Birthday-Interlude); RIP DJ MU aka Fitchie https://domm.plix.at/potd/2026-06-18.html
Today I learned how to pause a systemd timer: First stop it, then schedule a "throwaway" unit to start the timer again:
systemctl --user stop some.timer
systemd-run --user --on-active=3h --unit=resume-timer systemctl --user start some.timer
Today I'm saying goodbye to the "4" at the start of my age.

Today Vienna felt like Beihai (which is the hottest place I've ever travelled to).
