Latest of Changelog

Upiorek

, .

Anna Studniarek is Polish translator for most of Cosmere books, but not for Mistborn, which was translated by Aleksandra Jagiełowicz. I think that she initially planned to translate (some of) names to their Polish equivalents, similar to what Jerzy Łoziński had done with The Lord of the Rings, (sidenote: n.b. negative feedback which Łoziński’s translation received is probably the reason for most Polish translators to think twice before they change any original name.) but she changed plans. She left a single unnoticed “Upiorek”, a translation for the name of one of characters, Spook. (sidenote: “spooky” can be translated as “upiorny”) It’s one of these things you start noticing when you re-read books, but it still took me a minute to connect the dots.

Ledgerify 0.2.2

, .

I released Ledgerify 0.2.2. It has only one fix: it stops complaining about transactions with 2 postings with different currencies and different signs, but instead it correctly recognizes them as currency exchange.

i3a-scale-cycle

, .

I added a new script to i3a: i3a-scale-cycle. This allows to use a single comand to predefine some scaling factors for Sway and cycle them. I generally don’t have problems with small letters, so I don’t use scaling, but sometimes my eyes are to tired to bear them any longer. Usage example: i3a-scale-cycle -f 1,1.25,1.5 --next

Framework 13

, .

I bought a new Framework 13 laptop, AMD 7640U version and installed Debian Trixie on it. So far everything works, except Thinkpad’s USB-C dock, which spams GET_CABLE_PROPERTY failed (-5) message to dmesg. But the fight’s not over yet!

I kinda’ missed that this laptop comes with 3:2 screen ratio and I’m not used to HiDPI screens and I wasn’t prepared for that and had to improvise. I fell in love with this ratio though. It reminds me my old 4:3 monitors.

For me the best scaling factor was ~1.3, but I disabled scaling and increased font sizes for terminal and some programs. Fractional scaling crashed imv (imv bug) and didn’t work in XWayland apps which looked blurry. Other than that, it was OK.

Fan is LOUD when it turns on, but it only turns on when I play a game, compile things or do I/O-heavy stuff.

Speaking of games, I bought this laptop, hoping to play Baldur’s Gate 3 on it and I’m glad to say that it plays very well with quasi-high video settings. Vulkan renderer provides a big performance boost, compared to DX11, but has some strange artifacts: randomly shows black boxes. It can be worked around by setting fog details to high. Apparently it’s a known hack/workaround.
