@RydwolfPrograms must be a British culture thing
and by extension countries that derived from British culture
because that's always been something I've known of since 2010
what the hell
around here nothing would even happen except online before midday lmao
It's probably something like a gentlemen's agreement
and speaking of online, thanks to time zones i feel like jokes lasting as long as from late on the 31st to early on the 2nd is common for websites
especially for how much effort can go into some
it's more for physical pranks I think
oh like stuff that gets put up overnight
that makes sense
12:48 AM
like this is something I heard in 2nd grade 13 years ago :p
internet pranks weren't as prevalent back then :p
yeah, I remember that from my childhood, but these days since I only interact with people online there is no such thing and jokes usually go from the 31st to ending on the 1st or early on the 2nd like unrelated string said
always funny when people show up and say "well it isn't april 1st yet" like yes, timezones exist, and if we only did april fools when it was 4/1 in every timezone we would have negative 2 hours a year
there hasn't been as many elaborate jokes since 2020 I feel
except for r/place last year
It's daylight savings here and I'm going to get confused when talking about timezones for the next week
I now understand why programmers hate dates
that ended this morning here :p
Yeah, it ended here as well
I guess you're still two hours behind me
1:35 AM
@︎︎ᅠ yes, users right, if i want to do something in koltin i typically search "java <x>"
@︎︎ᅠ use regex

A: Sandbox for Proposed Challenges

JacobShortest distinguishable slice code-golf string For this challenge, a slice of a string is defined as an upper and lower index that can "cut" a piece of a string. All characters between those indices (inclusive) are part of that slice. If the upper index exceeds the string's length, the overflow ...

@hyper-neutrino in that case, I've still got time to announce MetaMetaGolfScript. It's like MetaGolfScript, except MetaMetaGolfScript-N solves several PPCG questions at once by overloading on the types of the inputs.

CMQ: How to determine the shape of a matrix from its diagonals?
2 hours later…
1:27 PM
Let's define a language called brainfiretruck that is a derivative of brainf--k, but in every loop, the number of < and > must be equal. Obviously, brainfiretruck is not Turing-Complete because if a loop is not an infinite loop, it can execute at most $p$ times where $p$ is the maximum number a cell can hold. Then does there exist a polynomial algorithm that determines if a given Brainfiretruck program of length $n$ halts?

make that a challenge
2 hours later…
6:47 PM
@lyxal Didn't we both lol
The United States isn't exactly famous for having a friendly and distant relationship with Britain throughout its history :p
I don't even get out of bed before midday on weekends
6:59 PM
@TwilightSparkle I think so, but it'll take me a while to demonstrate why I think so
7:53 PM
Well, no, Bjarne. Array is very clearly a stack-allocated (unless declared static) fixed size (unless VLA) contiguous (at least in virtual memory) region of memory usually used to store elements of a single type. A better idea would be to call it da or dyarr or dyarray as it is a dynamically allocated array. Simply calling it an "array" would be no good. — user426 Oct 12, 2021 at 7:14
Bet this guy's fun to be around
I like how they go into a discussion about how the existing terminology for something is bad and argue against people's suggestions because they're inconsistent with the current terminology...that would be replaced in that scenario
(I'm gonna start beginning all my pedantic corrections with "well, no, Bjarne", that'd be hilarious)
Sort of like "so unfortunately you just blundered your camel"
8:29 PM
@RydwolfPrograms To be fair, there's a reason some languages call their dynamic arrays things like "vector" or "array-list"
...oh. I didn't see the context
@Bbrk24 yeah, arraylist makes perfect sense /srs
theres also "ListMap" is google guava lib

array-list suggests a List that is internally defined as an Array, which may be reallocated as needed.
And whilst array suggests a fixed length continuous memory of multiple elements, it doesn't require it.
I think most people assume arrays are contiguous chunks of memory
@ATaco which it is
Contiguous chunks of memory are pretty useful, they save on space
In some languages None of those properties can be guaranteed, unfortunately.
A linked list requires an extra byte per node. Even the largest array, on the other hand, only needs about 22 miles of space
Ah I guess Ruby does that too
10:30 PM
Doubly Linked List used to be my Go-to C List until I found out how easy it is to implement an ArrayList with realloc
10:41 PM
linked lists seem like they'd be more efficient than arraylists etc, but of course each element has to be suffixed with a pointer to the next one so it takes up more space, even if it isn't consecutive
The Biggest bonus to a linked list is the speed of inserting or removing elements. If you're reading more than you're writing, an arraylist is better.
yeah makes sense
linked lists are rarely the right answer
Arraylists also aren't terrible at inserting and removing, still being O(n), so a pretty good general use list too.
if you insert and remove more often than you index, linked lists are great
10:45 PM
not a very common use case though.
the other use is if you have variable sized objects and a really simple allocator
like in forth
@allisonlastname this
forth is fun
Even still, the cost of manually reallocating the array can't hurt that much in the scope of things.
if the list is your entire system, then yes it hurts lol
10:47 PM
i like forth
i solved a problem in it earlier and got 104 bytes, with some fairly normal looking forth
fully golfed java solutions were also around 100 bytes
Linked Lists also make good Allocators for microcontrollers or anything with fixed memory.
A: Sum every second digit in a number

allisonlastnamejonesforth, 104 bytes : F DUP UWIDTH 1 AND IF BASE @ / THEN 0 SWAP BEGIN BASE @ /MOD -ROT + SWAP BASE @ / DUP NOT UNTIL DROP ; Less obfuscated version: : F \ make sure we have an even number of digits DUP UWIDTH 1 AND IF BASE @ / THEN 0 SWAP ( accumulator value ) BEG...

yeah from what i know, allocators are mainly built around linked lists
another reason i like forth is the compiled code is roughly the same size as the source
in most cases
Forth is one of the First languages, innit?
i wrote a text preprocessor that compiles down to ~2kb
and that's including a 1kb buffer
it's from the late 60s/early 70s
so contemporary with original k&r c
not really suited to modern machines, but back then it was stupid fast
11:32 PM
@ATaco nope

pun missed :P
but i would also consider something older than fucking C to be among the first in the grand scheme of things--especially if we filter down to ones that are still relevant today
Lol true
But its only 2 years older
11:55 PM
@mousetail Just let the DOM do it
