More #codegolf #programming - this time it's for some space invader animations. (140 characters was not enough to make the game interactive)

✨ Behold the groundbreaking revelation: you can animate dots with simple math! 🤯 Code golfing has never been so exhilarating, or so... dotty. 🎯 Just when you thought life couldn't get simpler, here come the 16x16 dots to prove you wrong. 🎨✨

So I watched this video https://www.youtube.com/watch?v=RcVA8Nj6HEo

And I decided to check what "plus times plus" actually computes. Luckily, I have my own #LambdaCalculus compiling language, #Lamber f https://github.com/aartaka/lamber

So I ran "* + + 1 2 3" and got... 36. So a number from a #math operator applied to other operators and then to data. Which seems like a nice basis for math conspiracy theories. How many of the basic arithmetic functions can we combine, and to what result? Might even end up with lambda calculus #codegolf things, like this division function John Tromp listed with attribution to Bertram Felgenhauer:

def div fn (dividend divisor)
local F = fn (m f t)
m T' (fn (c) f : c t) id .
int (fn (f x)
(int dividend) T' (K x) ((int dividend) (F (int divisor) f) x)) .

Adapted to Lamber, of course. But not any more readable than it used to be. Which is a cool feature of LC—you can apply anything to anything and get something as a result, albeit with a really confusing program flow.

I'm that close to learning some logical language and trying to devise mine, with lambda diagrams as concept ideograms and function application as the only syntactic relation. Yeah I know I'm going crazy, but at least it's fun.

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.

#codegolf #programming

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!

This feels like a good game for #codegolf - writing compact solvers for it - brute force is OK but I'm also curious about better solutions

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.
```
My solution, featuring the new "apply nconc to register", &
```
(progn ^^ [ >> >> v [ & ^^ [ >> >> ] )

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.
