Did you know that "toot" sounds just like Russian word for "here"?

I'm Alexander Batischev a.k.a. Minoru; you might've seen me on GitHub: https://github.com/Minoru I've been dabbling in functional programming for 7 years now. Mostly Haskell, but interested to learn from other languages as well. Hobbies for when I'm AFK: reading, cycling, pretending to learn how to draw.

Toot!

🔎 Sudoku for Android

Google Play:
1st result: "Please accept our ToS bef—". Uninstalled.
2nd result: looks promising, but drains battery even when not in use. Uninstalled.

I want to play already, so let's switch gears!

F-Droid:
1st result: Sudoku variation, I want vanilla.
2nd result: variation again.
3rd result: yet another variation.
4th result: direct hit! "Easy"puzzle took 15 minutes to solve.

Good job Open Sudoku! https://f-droid.org/packages/org.moire.opensudoku/

Sorry I can't tell more about it — I think I'll spoil the fun. Read it, it's short.

Computers are hard.

I just published #Newsboat 2.21: https://newsboat.org

The program is three years old already. Can you believe this?

#Debian replaces key-signing parties (where you have to appear in-person to get your key signed) with a more relaxed approach where you just sign your Debian-related work with a key for a few months, and then it's deemed to have enough of a history to be signed by others. IMHO this is an excellent idea, because at the end of the day, GPG is only used to verify that your contributions are coming from you, and it doesn't matter what name and photo your government-issued ID contains.

Spent something like 2 hours figuring out why ITM output can't be decoded, only to discover that the clock rate is not 8 MHz as I originally thought — for STM32F411E-DISCOVERY, it's 16 MHz. And I can't even remember now why I got so confident that it's 8 MHz.

Interesting research: recognizing handwritten digits by treating each written pixel as a cell that knows what other cells surround it, and where up/down/left/right is. Each cell communicates with its neighbours and decides what digit it is a part of. Fascinating!
