One month is plenty of time, so the first days after the theme announcement can be spent on brainstorming.

Over the weekend I have been a bit bored so I decided to create a very minimal snake game in JavaScript that ended up being only 1,422 bytes. The game is playable at https://rustydev.codeberg.page/tinysnake/.

Look through your tools from previous years if you do have them, or do your research right now, to not be surprised when the theme drops.

#CodeGolf #SageMath #OEIS

Okay, I admit it: I was code golfing today.

The subject was Bernoulli numbers. Many clever and incredibly complex algorithms have been devised to calculate them for large arguments and resulting in implementations so arcane that they leave mere mortals in the dust.

That’s why I was surprised to find for Bernoulli number with an even index an one-liner for SageMath.

Here it is—84 bytes is the benchmark now; who can beat that? [Naturally, simply calling the built-in function isn't allowed.]

B=lambda n:matrix(2*n,lambda r,c:(c<r+2)*binomial(r+2,r-c+2)).det()/factorial(2*n+1)

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!

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

More here: https://github.com/kesiev/baatato

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

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...
