@Bubbler It took me a while to understand what was going on--you push the numbers from 9 through 0 and then print them all at the end, so they come out as 0 through 9 because stacks. Nice!

@Bubbler @AidenChow Should I change ASCII-Piet to use letters that match the order of the Piet color cycle? So the color table would be represented by

abcdef
ijklmn
qrstuv

instead of the current

tvrsqu
lnjkim
dfbcae

Q: Solve NP-Complete problem with polynomial average time

Write a program that solves any NP-Complete problem. On average, our program should solve the problem in polynomial time. That is, there should be some \$k\$, such that, for input size \$n\$, the program on average return the correct result in \$\text O\left(n^k\right)\$ time for a random valid i...

I lied about taking a break...

shame on you

Ginger

17:58

how could you

DLosc

@DLosc 35 codels (and I think there's room for improvement):

@DLosc for a hot second I thought that was Makina code

Pseudocode:

Push 1

Loop:
  Dup
  OutNum
  Push 1
  Add

DLosc

@mathcat That's entirely up to you, and don't let Radvylf crush your dreams

ophact

@mathcat ...guess so

was sorta my fault

mathcat

hmm I can't seem to understand piet

DLosc

It's tricky. I can try to answer any specific questions.

Has the SE top bar changes broken some layout on chat's search page?

ophact

18:20

wait no

didn't read your message properly

but what it did do was break the mobile top bar

Turns out it did break the layout

Q: Please fix the chat top bar styling

The most recent rollout of the new top bar design broke the styling for the chat top bar - can this be fixed, please?

Ginger

18:38

how much are you willing to bet it'll take >2d for them to fix it

Adám

6–8 weeks.

Ginger

seems about right

ophact

btw if you're wondering why I lied about taking a break, it's because I genuinely wanted to take a break for one month, then I suddenly felt the need to golf for some reason so I stopped my break. the break didn't last long

Ginger

they've got the fever
the code golf fever

ophact

yes

indeed... I should be more careful next time

final feedback?

@RadvylfPrograms Can I has usrscrpt to fix topbar, if someone hasn't already made one?

Radvylf Programs

Chat topbar or normal one

allxy

18:54

you'll get a lot of popularity on meta if you do that :P

normal one

Ginger

damn I was about to do that

I want my meta cred

allxy

If it helps, I have a cached tab or two

Radvylf Programs

I'm busy right now, but I think all you'll need to do is copy over the <svg> data

allxy

Oh okay :P

o/ for now

Ginger

I'm going to do it then

Also, the chat topbar is completely broken: meta.stackexchange.com/q/377572/355458

caird coinheringaahing

ah right, it still works for me with the chat improvements userscript :P

okay so

it seems my original Disan Count program is pretty broken

time to rewrite it

Ginger

ಠ_ಠ

okay so

I have discovered a very strange bug

for some reason, automatons that travel off the edge of the program will warp around the program to the other side

but they only do it once?

dafuq

ok fixed it

@NewPosts alternatively, make the load go as long as possible and do your golfing then.

@DLosc Golfed the same pseudocode to 30 codels

tlrtttliurav??t
   r????eaiu tt

1 ! Dup       // [0 0]
Loop:         // [x x]
  3 Dup * < ! // [x !(x>9)]
  If 0: Exit
  Dup OutN 1 + Dup // [x+1 x+1]

Some horrible mix of Forth and Python lol

DLosc

23:24

@Bubbler Got to admit, I'm a bit disappointed the N x 2 shape is still golfier. I had some ideas for trying to get mine to 8 x 4 or 6 x 5, but the rules on how it picks the next block kept tripping me up.

Bubbler

23:46

@DLosc 27 codels with 3 rows, abusing no-op-on-error twice:

tlrsvld t
q?????f?t
fasueee t

Loop:
  1 ! + Dup OutN 1 + Dup 3 Dup * < ! DP+ %

First + is noop on first iteration, last % is always noop
