@infinisil:matrix.orginfinisil @room The next Nix hour is in 1h30! The topic this time is python.withPackages. If you have questions about this topic, you either can comment them in this issue, or ask them live via voice/chat in the meeting. There's also the livestream for just listening in šŸ˜„ 12:31:17

Takes me to an empty room
How about https://meet.jit.si/the-nix-hour?
14:19:43
@kadokusei10:matrix.orgkadokusei10But the video stream is over on YouTube due to some technical difficulties. Questions are on Jitsi chat.14:20:33

How about https://meet.jit.si/the-nix-hour?
Yeah, works. So I assume a mistake or a redirect is not working?

@kadokusei10:matrix.orgkadokusei10I just used the links from this message and they worked: https://matrix.to/#/!hArdrCQjixoTCqafnk:matrix.org/$kTpzoPouZz0EWQoVRlvNyAcFZfKeVX05oVOWGuUEZv8?via=nixos.org&via=matrix.org&via=one.ems.host15:04:41
@infinisil:matrix.orginfinisilAh yeah sorry, it's a bit messy with jitsi right now :/16:01:01
@infinisil:matrix.orginfinisil Pico: Yeah sorry it was a bit messed up. We switched over to this new URL last minute last week, but haven't updated all the mentions of the old URL 16:02:07
@infinisil:matrix.orginfinisilI'll have to figure out something better for the video streaming. It's currently impractical to ask questions in the jitsi, since you can't actually see the up-to-date video stream there.. (I had to turn it off because my computer freezes if I do)16:14:04

@infinisil:matrix.orginfinisil @room The next Nix hour is in 1 hour! We're having some fun today with a programming puzzle (don't know which one yet). Unfortunately I'm having Jitsi problems recently, so we're just gonna use YouTube today. Feel free to watch the stream and ask any question you have in the live chat! 12:56:49
@kadokusei10:matrix.orgkadokusei10Iā€™m terribly sorry but I will not be able to watch live today as I have to wake up extra early tomorrow m(_ _)m13:23:10
@infinisil:matrix.orginfinisilNo problem!13:55:08

Had some fun simplifying the code.

rec {
  lib = import <nixpkgs/lib>;
  interweave = item: elems: [item] ++ (lib.intersperse item elems) ++ [item];

  digits = ["0" "1" "2" "3" "4" "5" "6" "7" "8" "9"];

  tracingPipe = value: funcs:
    lib.pipe value (interweave lib.traceValSeq funcs);

  result = tracingPipe "123a45" [
    lib.stringToCharacters
    (lib.filter (char: lib.elem char digits))
    (map (char: lib.toInt char))
  ];
}

@infinisil:matrix.orginfinisilNice!15:39:11
@sofo:matrix.orgSofie Not no clue about if traceValSeq is what i should use here. But it seems to work so lol. 15:40:42
