What do you mean by "13s"?
If you mean the kind of pattern of the s(293) that has a rational side length... it appears that it was an incredible one-off mathematical coincidence. I just checked for others in its series, and all of them are beaten by other known patterns, and don't even make rational side lengths anyway.

CMegaC: Design an esolang that operates on more than one 'thread' (That is, more than one IP that operates independently or in lockstep with others), that is only TC when more than one thread is used.

emanresu A

uh look up Brian & Chuck

ATaco

Close, but Brian & Chuck operates only one thread at a time

Oh god Source configs satisfy this

Deadcode

02:05

@Deadcode Oops, there actually are others with rational side lengths, probably an infinite number of them. They're about exponentially sparse though. And none of them aren't beaten by other known patterns. So I guess it could make a code golf challenge, but since only one of them is a good packing in general, it might not be interesting enough.

@ATaco I'm not super familiar with it, but I think this is a core feature of Trilangle (which come to think of it was probably inspired by Hexagony's 6 IPs, which take turns Brian and Chuck-style)

rydwolf

There are too many langs with geometry puns

Hexagony, Trianguish, Trilangle

ATaco

Taking turns is just slightly out of spec, And too easy to design for

Source Configs for some fantastic reason allow you to loop, store data, so-on and so-on, but you can only do anything meaningfully on a separate "thread" to what-ever's looping.

Unrelated String

phenomenal

Trilangle's threads are IIRC actually concurrent/interleaved

is trees

ATaco

Hehe, Binary Trees

rydwolf

Finally figured out the formula, making the trump the only interactable part and the leaves visible as for aesthetics/recognizability

err, trunk

I can't get over how nice this looks relative to the amount of effort

(<2 days)

ATaco

Damn those lakes and rivers really make it

You convinced me to play with my own map generator btw

rydwolf

@ATaco Right? I figured it'd take way more complexity to make something convincing

@ATaco ooh nice

Is this perlin combined with some sort of fractal noise?

ATaco

Just Fractal-Perlin noise

rydwolf

ahh

ATaco

(With Cubic Interpolation)

My first implementation used Bilinear interpolation, don't do that

I'd like to try the same thing on the GPU to see how BIG I could get

I've managed to get my current terrain generation pretty fast, it's near-instantaneous for 512×512

The diamond-square is pretty fast ofc, and the water generation uses a janky pqueue sorta thing for choosing the best place to place the next water cell

Since I already draw chunks one at a time, I could probably make the terrain generation happen at chunk loading time if I wanted bigger worlds

one cool thing that was sort of accidental is that the map generation is currently toroidal

@rydwolf (I'd actually been curious for a while what Chrome OS's low power mode did that was so effective, and I guess dropping FPS is part of that)

Q: Convert to Pascal-ary

Your program must take integers \$S \geq 0\$ and \$n \geq 1\$ as input and output a list of \$n\$ integers \$(a_i)_{i=1}^{i=n}\$ such that \$-1 \leq a_1 \leq a_2 \leq \dotsb \leq a_n\$ and \$S = \sum_{i=1}^{n} \binom{a_i+i}{a_i}\$. By convention, \$\binom{m}{-1} = 0\$ for all \$m\$. Standard loop...

@rydwolf i'm pretty sure it just underclocks and undervolts

also turns off any normally on radios if it can like BT and wifi stand-by if you weren't using it

I have just discovered something bizarre

A video labeled as "AI tries to do [thing]" but it was clearly not AI

Like the jokes and the appearance of the video and the tonal inconsistency were like what you'd expect from a human-created shitpost

This is I think the first time I've seen a human impersonate AI rather than the other way around'

good news! Algol 68 is now in gcc!

@ATaco pretty sure android apps are unobservable if using only one thread because the compiler enforces using a separate thread for the UI and they don't have console output

@Themoonisacheese Only 58 years late

@ATaco Does BitCycle count?

Unrelated String

@rydwolf Botnik? Been around for a while and I think they might even predate modern LLMs, but IIRC they're a group who make all the "we trained an AI on [X] and this is what it produced" posts that are actually made by human-operated traditional predictive text models a la phone keyboards

I feel you 😭
The way I like to look at it is, momentary enjoyment contributes to long-term improved outcomes for my mental health, and that brings me a lot closer to things I find long-term satisfying

@mousetail'he-him' ...come to think of it I'm definitely starting to approach this now that I've uninstalled Conda by renaming a directory it uses and changing nothing else LMAO

@ATaco Does BitCycle fit? Each bit on the playfield could be considered a separate thread; they all tick at the same time (in implementations, they're handled one at a time, but their order is undefined behavior) and the language is definitely not TC with only one (since they're also the only way to store data and each stores one bit).

@mousetail'he-him' Lol, ninja'd

@betseg prrrrp!

You know you're a cat person when you're reading through the ancestry options in Pathfinder RPG and your reaction to the bipedal cat people is "Cool I want to play one" but your reaction to the bipedal dog people is "What the heck that's so bizarre why would they do that" :P

betseg

i would play both :3

I'm going to post this. Last chance for sandbox feedback.

Unrelated String

Crucial feedback that I offer my deepest apologies for not submitting when I saw it on the sandbox a week ago: nice title :P

One minor actual thing, come to think of it--IMO the spec makes this clear enough, but I am still reminded of how people asked if prefix/postfix notation was valid for the quandle challenge so that could be good to call out as one of many legal ways to serialize a tree for input

(and I guess it might actually be a little less clear here because of the note about being able to assume that "the" string representation is fully parenthesized--could be read to imply that no string representation other than infix is permitted)

not me not getting it for 10 minutes

@UnrelatedString Yeah, this is a good point. Its funny how sometimes being explicit about a way things are flexible makes them appear less flexible.
