Код-гольф в Яндексе: как нерды развлекаются

Что такое код-гольф? Это соревнование, в котором надо решить задачу по программированию (как правило, несложную), используя наименьшее количество символов. Соревнование довольно известное. Можно поиграть, например, на одноимённом сайте , есть целая секция на CodinGame , иногда такие соревнования публикует kaggle , была такая секция на HackerRank (сейчас её я не нашёл). В чём особенность таких задач? Низкий порог входа: решение можно написать с мобильника и оно будет занимать 10 строк. Но при этом есть большая сложность: чтобы избавиться от какого-то символа, в этом соревновании приходится идти на такие ухищрения, что мама не горюй. Некоторые конструкции очень неочевидные. Временами мы развлекаемся таким форматом. В какой-то момент на внутренних ивентах подняли свою платформу для соревнований, а потом она протекла и на внешние конференции. Эта статья — смесь разбора задач и истории появления соревнования по код-гольфу на конференциях Яндекса. Про нас и кодгольф

I've been annoyed by my lack of a way to put "multi-line one-liner" python code into my bash code with reasonable indentation.

This discussion suggested a workaround: Make the first line `if 1:`, then you can indent all you like on the second line. Good enough for me!

Allowing indented code for `-c`

Jon Crall posted this feature proposal on the Ideas mailing list and a GitHub issue in April. It needs wider discussion, so I’m re-posting it here. I’ll add my own comment below. The Python CLI should automatically dedent the argument given to “-c”. I raised this issue on the Python-Ideas mailing list and it got some positive feedback, so I’m moving forward with it here and in a proof-of-concept PR. Pitch I have what I think is a fairly low impact quality of life improvement to suggest for t...

Yo Dawg! I heard you may want to #print a #poker #card sized version of a minimal #balatro like #javascript #game #sourcecode. So you can poker while you poker. #baatato #codegolf #deadmeme

It's time for a new #javascript #opensource #codegolf thingie. #Baatato is a 2KB reinterpretation of the iconic Poker-inspired deck-building game we all know!

(Resize your browser window to a square shape to see the full game screen. It should also be playable on portrait mobile devices.)

So I've been trying to code-golf a JS-free menu bar from my website. The <details> HTML tag proves very useful to have a JS-free foldable menu in mobile mode, however I still need to duplicate the whole menu for desktop mode as I couldn't lock <details> to the open state in desktop mode even with media queries.

The ::details-contents pseudo-element sounds promising though, let's see if it works! It's not widespread yet but just landed in Firefox 143: https://developer.mozilla.org/fr/docs/Web/CSS/::details-content

My bar for stability is at least some time in Firefox ESR, so it won't make it to my website for a year or two. #HTML #CSS #CodeGolf #NoJavaScript

Le pseudo-élément CSS ::details-content représente le contenu extensible/collapsible d'un élément <details>.

🤦‍♂️ Welcome to the mystical land of branchless programming, where we #sacrifice #readability for the thrill of turning C code into an indecipherable mess. 🤯 It's like code golf for masochists who enjoy watching CPUs hyperventilate from all the caffeine-induced optimizations! ☕️🔧

Using #GNU as Assembler (not Assembly, but the Assembler) and ld Linker to spit out a working BMP gradient image.

Yeah, you read it right. I'm not using #Assembly to produce an image. I'm, instead, using Assembler directives and macros during compile-time to generate a binary file that happens to be a valid image (BMP) file.

File: tonishing.s (GNU Assembly file)

width = 320
height = 240
area = width * height
_begin:
    .ascii "BM"
    .int fileSize
    .int 0
    .int (_rasterdata - .)

_infoheader:
    .int infoheaderSize
    .int width     # width
    .int height    # height
    .short 1       # planes
    .short 24      # bitcount
    .int 0         # compression
    .int 0         # imagesize
    .int 11811     # xpixperm
    .int 11811     # ypixperm
    .int 0         # colorsused
    .int 0         # colorsimp

infoheaderSize = (. - _infoheader)

_rasterdata:
    n=area+1
    .rept height
        .rept width
            byten=((n*255)/area)&0xFF
            rn=(192*byten)/255
            gn=(64*byten)/255
            bn=(128*byten)/255
            .byte rn,gn,bn
            n=(n-1)
        .endr
    .endr

fileSize = (. - _begin)

File: run.sh (Shellscript)

#!/bin/sh
clear
rm astonishing.bin
rm tonishing.o
as tonishing.s --64 -o tonishing.o
# The pun is _astonishingly_ intended.
strip -R .comment -R .note.gnu.property tonishing.o
ld -n -x -s -N --oformat binary --unique=.note.gnu.property -o astonishing.bin tonishing.o
magick identify -verbose astonishing.bin

I run the whole thing with... wait for it... #nodemon!

That's right: the tool intended for #Nodejs hot-reloading, is being leveraged for GNU Assembly, which is itself being leveraged for compile-time instructions to produce a whole BMP image.
nodemon -e "s sh" --exec ./run.sh
While I have a #Codeberg account, it's under my personal name where I published old projects from #GitHub, so I should do a second account for this pseudonym... but I'm not sure if this is against the Codeberg rules... So I'm posting the whole thing through a Calckey post instead.
