Can you find a formula for this prime sequence using the fewest number of bytes?

The period is 210 for the 3-term version, but the period for the 4-term version is unknown. Interested in theories for what it could be.

這段 javascript 能簡化掉重複的二個 toHtml 呼叫嗎？

Could the two `domTool.toHtml` calls in following function eliminate?

```js
const h = (...args) => {
const x = tsjson.html(...args)
if (typeof x == 'function') {
return (...args) => domTool.toHtml(x(...args))
}
return domTool.toHtml(x)
}
```

I made a simple picross puzzle game that fits in 1024 bytes of HTML. Try it at https://js1024.fun/demos/2023/15, or read my blog post about it at https://evanhahn.com/js1024-2023/.

Hindley and Seldin had an exercise that says to find two lambda terms P, Q which do not have β normal forms but PQ does.

It's not the hardest exercise once you have the idea of passing stuff around in the usual Ω fashion until you can shuffle a constant function onto the front, but I think it could be a fun #codegolf challenge for a lazy afternoon.

My first attempt was
\[ P= (\lambda xy.y (\lambda x yz.z)(x x))(\lambda xy.y (\lambda x yz.z)(x x)) \] \[Q = (\lambda x y z. y (x x)z)(\lambda x y z. y (x x)z)\] #lambdacalculus

A friend of mine minified Bitshift Variations in C Minor down to 179 bytes:

gcc -xc -oa -<<<'i;n;g(m,t,o){m=("GTj?TG?5"[7&t]+!(n&12|t&2)*9)*i>>o&m&24;}main(s){for(;;putchar(g(8,n=s>>4,8)+g(n,n^s/8,6)+g(n/3,n+s/2%3,6)+g(n/5,n-s%3,5)))s=++i>>10;}';./a|aplay

This looks like a fun #codegolf #challenge and a fun programming challenge even without the golf: https://codegolf.codidact.com/posts/288535

@Are0h Here, meet https://www.codidact.com as well, which was born out of the previous Stack Exchange debacle. Consider trying it for Q&A, it's still small & needs more people. So far has communities for #writing, #outdoors, #photography & #video, #science speculation (#scifi #writers), #cooking, #ElectricalEngineering, #judaism, #languages & #linguistics, #SoftwareDevelopment, #mathematics, #christianity, #CodeGolf, #music, #physics, #Linux / #Unix, #computer users, & #TTRPG enthusiasts. [2/2]

Took the time to release the source code of all my #codegolf / #sizecoding #demoscene productions (64, 128, 256, 512 bytes Linux #fbdev and #tic80) https://github.com/grz0zrg/codegolfing

#CodeGolf this! Surely there is a better way to do it

@TodePond Gives a new meaning to #codegolf

Wow, this #CodeGolf question is almost two years old and people are still trying to improve answers, many in "normal" languages rather than languages optimized for golfing. Some neat reading here. :-)

What happens when you let code golfer write a UUID polyfill?

5335 points in stack overflow, for code, none seems to understand:

function uuidv4() {
return ([1e7]+-1e3+-4e3+-8e3+-1e11).replace(/[018]/g, c =>
(c ^ crypto.getRandomValues(new Uint8Array(1))[0] & 15 >> c / 4).toString(16)
);
}

Somehow I think I'm not going to use that, if your code is so hard to understand it's discussed non-stop, it's a 🚩

🎆 Fireworks time! 🎆

Just 260 characters (incl. a lot of sine waves) to create this never ending celebration!

It's now open sourced and fully annotated 🧑‍💻

Added a nice fadeout, and reduced it to 260 chars!

```

r=rnd::_::cls()srand()for i=1,20 do
m=8+8*r()q=(t()/m)%1
x=64+q*256*(r()-.5)y=128+sin(q)*64*(r()+.8)s=sgn(sin(q+.8))l(x,y,s-1,7)j=2*(q-.2)k=m*(1-(1-j)^9)for u=0,1,.1 do
l(x+sin(u)*k,y+cos(u)*k,sin(q-.9)\1*s,q>.45 and 1 or 8+i%8)
end
end
flip()goto _

I enjoy #codegolf and I'm decent at it. I'm happy to apply those skills to #pico8 games that need to squeeze more tokens and/or bytes out of existing code to make room for more features or levels. #gamedev

#LovebyteTCC Tiny Code Christmas, Day 11 Expert Challenge: Create a Hollow Cube that rotates in 3D along at least 2 Axis in 256 characters or less without using the Line of Triangle functions. You can use any technique at your disposable, e.g. Raymarching, Raycasting, Voxels, Raytracing, Drawing your own a fat wire cube, etc.

Here is one of my #tic80 versions of the regular voxelcube (most of them between 130 and 148 characters of code)
