The Nineteenth Byte

12:03 AM

@cairdcoinheringaahing I feel like it kinda depends on how complicated each of those pieces of information is, gimme a min to read this challenge

caird coinheringaahing

One of the bits of info is the proof of the Riemann hypothesis, another is the complete works of shakespeare, but where every letter is replaced by the script for the bee movie :P

des54321

sounds perfect :P

Ginger

I see no issues here, it should work fine

des54321

this does seem like a pretty good KOTH, still reading though

definitely will require complicated bots though, there are a lot of pieces to this

i feel like im not quite certain I fully understand double conveyor belts, do those always move the bots twice or can they chain if you get moved from one conveyor to another?

caird coinheringaahing

Basically, the double conveyers "activate" twice, whereas the single ones only "activate" once

des54321

I do feel writing good bots for this will be hard though, there are kinda a few too many moving pieces

yeah, the more I think about this the more complicated i realize it would be to code a bot for it that actually does well

caird coinheringaahing

So, the thing I found about playing the IRL version of this is that even the best laid strategies can go chaotically wrong. I suspect a simplistic bot might actually do quite well

des54321

quite possibly

caird coinheringaahing

@Wezl'lo-ol' I'm tempted to remove walls from the spec tbh, they're a bit of an annoying edge case

des54321

I feel like if i wrote a bot for this it would mostly consist of various conditionals for what it wants to do in certain situations, like if its on the big conveyor loop in the center stay on that until its close to a checkpoint, move towards a checkpoint if its in the right area, etc etc

removing walls might help, or just turning them into completely impassable spaces instead

I do feel like some sort of graphical controller that actually shows the bots moving around the field is almost necessary for this

because otherwise it would be too hard to debug stupid shit your bots are doing

Q: Fill the rectangle

Challenge In this challenge, you have to fill an \$M\$ x \$N\$ rectangle grid with the most \$A\$ x \$B\$ rectangle pieces possible. Requirements: The sizes of the \$M\$ x \$N\$ rectangle grid is always bigger than the sizes of the \$A\$ x \$B\$ rectangle pieces. In other words, \$min(M, N) ≥ ma...

probably not that hard to whip up something basic with pygame that just draws a bunch of rectangles and circles for everything

caird coinheringaahing

I'm going to write a normal controller first, then maybe turn it into a graphical one :P

That's weirdly specific

Also, 2 months is a crazy long time for answers to wait before being safe

@cairdcoinheringaahing OK then

Thanks + Thanks

Another upvote and I'll be 777 rep!

caird coinheringaahing

It's generally a good idea to ask for feedback before posting a zero score cops-and-robbers, especially if you haven't really gotten any feedback before. It's not too bad as in, but could've done with a bit of cleaning up before posting

I'll give it a quick edit

caird coinheringaahing

Actually hang on, no, I'm going to leave some comments instead

Eman yalpsid

Why is this of course

could've been 5000 characters ;-)

caird coinheringaahing

@Emanyalpsid Perl 6 isn't a thing

And Raku is generally considered a completely separate language to Perl

Eman yalpsid

@cairdcoinheringaahing Just to avoid confusion

As technically it IS called perl6 and raku

caird coinheringaahing

I'd suggest changing "An answer is safe if it is not cracked until two months after the question is posted." to "An answer is safe if it is not cracked until two months after it is posted.", and potentially lowering the time (7 days, or 2 weeks are normal for CnRs)

Also, if you're going to copy-paste rules/specification from other challenges, at least edit it to make sense for your challenge

Eman yalpsid

2:33 AM

Wait what

I'm confused

This robbers-and-cops challenge challenges the robber to write ... The cop should provide the following information:... Maybe is it supposed to be cops

caird coinheringaahing

Yes, Robbers are supposed to find the hidden information

Eman yalpsid

oh ok

fuck it

Congratualations to me for writing cop for robbers and robbers to cops

so um basically i copy pasted the flag part and i want to edit it to - Flags must be revealed to avoid obscure combinations.

@cairdcoinheringaahing you there?

caird coinheringaahing

Yep

Eman yalpsid

why delete this

The shortest safe answer by byte count wins.

caird coinheringaahing

That doesn't make sense for Robbers

Eman yalpsid

2:39 AM

oh ok

caird coinheringaahing

In a Cops and Robbers challenge, the Cops have a different winning criteria to the Robbers, as they're trying to do different things

Eman yalpsid

yeah done

phew, cnr is a strange thing to me...

Thank you pretty sure you gave me that upvote

caird coinheringaahing

I didn't actually

Been too busy editing the challenges into shape :P

Eman yalpsid

um

nvm

caird coinheringaahing

Don't worry, I tend to only upvote challenges I answer, and I have a couple of ideas for this I might try

Eman yalpsid

I tend to only upvote challenges I answer? hmm

idk why but i always star stared messages

caird coinheringaahing

@Emanyalpsid I only upvote challenges I think are a net positive to the site, and I only answer challenges I think are a net positive to the site, so, very often, they go hand in hand

Hai guys

Radvylf Programs

Am I that bad at JS?

emanresu A

Lol

Radvylf Programs

It turns out I just used a ++ instead of -- in a for loop (for a shuffle)...kinda wack that it SIGILL'd

Bug maybe?

emanresu A

Yeah, I'd try to repro it if I were you

It's gotta be a compiler error, right?

(Also, you might have discovered a major security vulnerability)

Radvylf Programs

Maybe, but it's unlikely

And trying to boil this down into an MCVE isn't going to be fun

But y'know what, I don't have anything else to do

I've already boiled it down to 6 lines yikes

emanresu A

3:15 AM

Maybe try running it in v8 if you can isolate the version your browser uses?

Radvylf Programs

This is it:

var points = [...Array(2)].flatMap((_, y) => [...Array(2)].map((_, x) => [x, y]));

for (var i = points.length - 1; i > 0; i++) {
    [points[i], points[0]] = [points[0], points[i]];
}

It takes about two seconds to awsnap the tab for me

thejonymyster

i>0, i++?

i have no context but that seems wrong :P

Radvylf Programs

Yeah, it is

It's a minor bug that should just do an infinite loop

It awsnaps after over 100 million iterations

Let's see if it's a consistent number

It is

112813857

emanresu A

@RadvylfPrograms How did you get this?

Radvylf Programs

Interesting, this number shows up elsewhere: github.com/xtuc/webassemblyjs/issues/718

@emanresuA console.loging every 1000 iterations, to get a rough estimate, then logging every i after that estimate until it died

emanresu A

3:21 AM

So, you just reached the JS heap limit. Oh well :P

Radvylf Programs

Probably something boring like that, yeah. But SIGILL?

Weirder:

var points = [0, 1];

var x;

for (var i = points.length - 1; i > 0; i++) {
    x = points[i];

    points[i] = points[0];
    points[0] = x;
}

It doesn't have to do with using the [x, y] = [y, x], so OOM is less likely?

That changes the number of successful iterations though (increases by ~6000), so maybe it is just OOM and SIGILL (no idea what would be using more memory though)

PyGamer0

@emanresuA thats stack based..

emanresu A

Oops

Radvylf Programs

Hmm, it eats up 2 GB of memory instantly, so probably just...oh wait I'm an idiot swapping with incrementing is means that it'll grow the array to a larger and larger size

OOMing with a SIGILL is weird but probably intentional

emanresu A

@RadvylfPrograms It took me a while to realise that that didn't stand for Order Of Magnitude
