Simplest way to draw HAKMEM 149 based structure without offsetting / adjusting the seeds, turns out that using one unsigned shift is the

Loop is optional.

Two versions for the two different algorithm precisions. Adapted for 512x512.

Code is for a grey scale one but i made a colored one based on exponentially mapped iteration count (classic way to color fractals), this somehow require to offset coordinates for nice colors.

I have succeeded in creating a polyphonic #WebAudio soundscape, with 140 characters.

So proud/not proud with the cheats needed to get this code down to size.

Doing some table generation in awk, and is there an easier way to do "all fields n to NF" than this?

function combine(combn, combs) {
for (; combn<=NF; ++combn) {
combs=combs "\t" $(combn)
}
return combs
}

I could use printf on the fragments, but the annoyance is that loop, instead of
(string-join (cddr fields) "\t")
or whatever.

More golf!

194 bytes of code, which compresses to 140.

I have significantly better looking versions, but I need an extra 9 bytes to do it!

Another #CodeGolf puzzle for #JavaScript #WebDev people:

I have n functions that type one argument of the same type and return a boolean.

The current usage is:
function a(b) {
return c(b) && d(b)
}

I boiled down a to
a = (b) => [c, d].every(fn => fn(x))

I assume, this can be further boiled down via bind/ #PartialApplication/ #Currying

What do you think?

If you'll forgive the daily throwaway challenges, here's another one. To quote from the link,:
```
'(a (b c) d (e f))

overwrite the b with the f.

the ability to use & to create portals opens up a world of puzzles/golf challenges.

I modified my little NUD language to basically be vi but for #lisp lists. Er, if I do say so. YMMV

Alternately, propose your own challenges for me and others to solve (I'll add them to the git here: https://codeberg.org/tfw/nud/src/branch/master/golf.org )

If anyone wants help trying or has other commentary, lmk here or during the show.

A tiny way to compute a square / triangle wave at the same time without conditionals, only basic arithmetic and shifts.

This can be used for #oscillators or animations etc. #algorithm is a variant of HAKMEM 149.

Can also be used to draw a square. (And other shapes, see previous toot)

Code also shows how to draw a diamond shape by rotating the square by 45°.

There are two versions, optimized for size and optimized for speed.

I've finished and released the #interpreter for my new esoteric #programminglanguage , Bespoke!

https://github.com/WinslowJosiah/bespokelang

I've also been having lots of fun trying to solve #programming challenges with it, including #codegolf challenges.

After a large community effort, Code Golf (https://code.golf/) now supports unrestricted execution and answer checking for their growing list of problems in #APL (Dyalog APL). APL is listed in the "experimental" section of the supported languages list – once a sufficient number of people have submitted solutions, it will move to the main list of languages and get a leaderboard. Please help APL achieve this by exploring the site and submitting APL solutions. #Dyalog #DyalogAPL #CodeGolf

Python oneliner: add random diacritics to vowels. The input is "SEQUOIA sequoia". Prints e.g. "SÉQÜÕÏÁ sëqûôìâ".
import random;print("".join((chr(ord(c)&32|b"aimsz"["AEIOUaeiou".find(c)%5]+random.randint(95,98))if c in"AEIOUaeiou"else c)for c in"SEQUOIA sequoia"))
Edit: deleted the old versions because they might give away how the program works.

FFmpeg boasts up to a 94x performance increase using hand written assembly!

Via TomsHardware:

https://www.tomshardware.com/pc-components/cpus/ffmpeg-devs-boast-of-up-to-94x-performance-boost-after-implementing-handwritten-avx-512-assembly-code

"The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.

This development is particularly valuable for users running on high-performance, AVX-512-capable hardware, enabling them to process media content far more efficiently. There is an issue, though: Intel disabled AVX-512 for its Core 12th, 13th, and 14th Generations of Core processors, leaving owners of these CPUs without them. On the other hand, AMD's Ryzen 9000-series CPUs feature a fully-enabled AVX-512 FPU so the owners of these processors can take advantage of the FFmpeg achievement."
