@taRadvylfsriksushilani I was trying to make the screen solid white and joke that that's what happens when you point a camera at the Actual Sun but it broke so :/

I can make the sun solid white if you want tho

Maybe I could artifically lower the bandwidth...

Like have a queue, and send a maximum of one packet every x milliseconds

Well, I'm not really making a protocol. It's like taking one protocol and gluing it to another one, with a hedgehog stapled to the side of it

It's not "Is the vote on a question or answer"

thejonymyster

@GingerIndustries very weird, it was only showing up on my side then. why would imgur be like this

caird coinheringaahing

I think it might have something to do with repcapping, a brief examination looks like it only appears on days I've gotten close to +200

Hm yeah.

I don't see anywhere i have [x] and then (y) later on the same day.

All the rep "lost" to the cap is in square brackets, as well as the last bit of rep gained before the cap

Ginger Industries

spectral analysis shows that the disk is made of MeshStandardMaterial

Wheat Wizard

I have a bunch of [0]s as well. Those are sort of weird.

caird coinheringaahing

@WheatWizard Are those on days where you reached +200?

Wheat Wizard

10:30 PM

Yes.

So it's not rep lost.

It's just rep amounts that interact with the rep cap.

caird coinheringaahing

I think that represents upvotes with no rep gained due to the cap

Not sure what exactly is going on there.

I guess someone downvoted and undownvoted, but idk why they are in squares.

caird coinheringaahing

3 is a downvote, 2 is an upvote (event ids), so I think you hit the cap, then got downvoted, then either upvoted or undownvoted

And it looks like the last bit of rep you get before the cap is in brackets as well

Wheat Wizard

I would think the -2 would be (-2) though.

caird coinheringaahing

Can't see ay questions about it here, maybe worth asking?

Wheat Wizard

10:34 PM

I would also think that I if I hit the cap and gained then looks like ~10 more upvotes a downvote wouldn't actually put me under the cap again.

Ginger Industries

@GingerIndustries screw it, I'm going to fix the rotation code later because I'm too lazy to do it now

caird coinheringaahing

@WheatWizard Unfortunately, that's not the case. If you hit the cap, any and all positive rep is then discarded, but negative rep can drop you under it

Wheat Wizard

Ah ok.

caird coinheringaahing

I agree tho that it should be "We take the net rep change in a day, and if it's over 200, we cap it" rather than "Once you hit 200, no more increase, but can still decrease"

If you get 50 upvotes in a day and one downvote, you can get less rep than if you get 21 upvotes and 5 downvotes, depending on the timing

11:08 PM

@SandboxPosts This would make a good CMC.

I'll give imaginary brownie points to anyone who tries it in Pip--there are several ways to do it, and the shortest that I've found so far is not obvious.

3‿3⥊4=↕9 seems like the obvious way to do it in BQN... I wonder if there's anything shorter.

@DLosc Found two other solutions that tie my previous shortest

caird coinheringaahing

6 bytes in Jelly

DLosc

11:23 PM

@cairdcoinheringaahing This?

caird coinheringaahing

Right, equals exists. I have this :P

DLosc

Ah, nice

(I just pretended Jelly is a left-to-right version of BQN that has a "split into chunks" builtin, and it worked. :P)

user

A naive solution in APL would be 3 3⍴1@5⊢9/0

caird coinheringaahing

@user Why replicate 0 when you can get the range to 9, then check for =5?

(or =4 if using 0-indexing)

user

Oh right

So 3 3⍴5=⍳9 or 1=∘.×⍨⍳3

DLosc

11:32 PM

@user Ah, nice. The first one is exactly equivalent to my original BQN solution. The second one, ported to BQN, is 1=×⌜˜↕3, which is one byte shorter.

user

Oh cool, it's got a separate operator for outer product

DLosc

Yep

caird coinheringaahing

5 bytes in Jelly then

DLosc

Aha

I take it that þ automatically turns an integer into the corresponding range?

caird coinheringaahing

Yep

Like most array things in Jelly :P

DLosc

11:46 PM

Hmm, and the resulting ×þ is a dyad? I think that's the only thing that would account for this behavior.

(Also: new smiley alert ×þ)

Adám

@user Also 3 3⍴¯5↑1 which is probably the fastest.

user

Ah cool

DLosc

@Adám How does that work?

Adám

J can do 4=i.3 3

↑ is "take", so we take the last 5 elements from 1, padding with zeros, then reshape (cyclically) to 3-by-3.

caird coinheringaahing

@DLosc Yeah, the quick þ takes a dyadic link f, and two lists (one on the left, one on the right), and runs x f y for each elements x, y in the arguments

DLosc

11:51 PM

@Adám Oh, lol

Works in BQN too: 3‿3⥊¯5↑1

Adám

ofc

DLosc

I laugh because I just ran into the zero-padding and "negative left arg means take from end" behaviors while golfing my BQN answer to How many times can I skip a stone. But of course I'm not enough of an array programmer yet to realize that a number could act like a single-element array.

Adám

~~act like~~ is. ftfy

caird coinheringaahing

@cairdcoinheringaahing I'm almost positive that 4 bytes is possible here, using some property of 2, 2 that doesn't apply to 1, 1 or 3, 3

Aka, 3fþg or 3<dyad>þ with dyadic f, g or a two byte <dyad>

DLosc

@Adám I'm not enough of an array programmer yet to state that equivalence confidently. ;) (And I think the details are a little different in BQN than in APL? I didn't understand that part.)
