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

Meet me and some #RetroComputing #hackers at the #VintageComputing assembly on this years #39C3 in Hamburg!

We will present some historcial running machines #AnalogSynthesizer patching, #AnalogComputer tinkering (with a #Vectrex as an #oscilloscope), and #BASIC #CodeGolf and #RetroGame workshops!

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!

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

🤦‍♂️ 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.

I kind of irrationally #CodeGolf my #Makefile rules, but sometimes I sit down to straighten out something awkward that bugged me for years, and get kind of mad when I seem to have been the first to actually treat `make` like the tool it is instead of as a broken shell script runner.

This time it was #Python #VirtualEnv setup:

```
dep: .venv/bin/pip .venv/lib/*/site-packages/__pycache__

.venv/lib/%/site-packages/__pycache__: .venv/bin/pip requirements.txt
.venv/bin/pip install -Ur requirements.txt

%/bin/pip:
/usr/bin/virtualenv $*
```

(Yeah pretend those are tabs. Yeah that is make's worst wart.)

I even use `!#.venv/bin/python3` in my scripts and hey presto everything just works everywhere and I can focus on the actual code.

I'm curious what cases I'm ignoring or missing here. Non-install upgrades may deserve a target perhaps...

I'm submitting a "creepy" entry to this 1KB JS competition.

I've currently got 6 whole bytes spare. Wonder what I'll use them for?
