Any thoughts on this sandboxed challenge (not mine, but the OP wants to run a popularity contest)?

Not many that you haven't already brought up, though I do think it would be VTCed as unclear if posted in its current state

I think adding some test cases will help for that

Redwolf Programs

There are over 10k people who haven't done part 2 of yesterday

pppery

Part 2 yesterday was definitely a pain to do

Redwolf Programs

It wasn't too difficult with the approach I used

But I mostly stumbled upon it by accident

Bubbler

It starts to require at least some amount of math/CS/problem solving/whatever

pppery

3 minutes

that was fun

second part is tough

just flipped the death rule into a survival rule lmao

second part is only tough if you're trying to be functional

Lyxal

Redwolf Programs

Man JS is not the right tool for the job here

pppery

I likewise spent a long time bugfixing part 2, ending up with 160/409

Unrelated String

lol

@Lyxal i only had to mess with deep cloning because i chose to

ASCII-only

@RedwolfPrograms definitely lol

HyperNeutrino

5:26 AM

i just ran a first pass to get the relevant "neighbors" for each seat to see which seats they need to care about for part 2

i assume it would've been too slow otherwise

hmm i'm wondering, should i share my template lol

Unrelated String

lol

it's a trade secret

Redwolf Programs

How long did y'alls take to run?

Got part one!

pppery

@HyperNeutrino Nope, my part 2 didn't do that and was fast enough

(it takes several seconds, which is long enough to be noticable when I run it, but not too long)

Redwolf Programs

Mine took like five minutes

Lyxal

okay it helps to read the part where it's applied simultaneously

HyperNeutrino

5:35 AM

oh, okay. then again i don't know how many runs my code did

89 apparently

mine takes 2 seconds (TIO timing)

ASCII-only

yknow what

charcoal wouldve been the perfect language for this...

Razetime

@ASCII-only PeekVonNeumann right

Redwolf Programs

My part 2 has taken like 5m already :/

Wait! It just finished!

ASCII-only

bruh...

what the heck did you do for part 2

Unrelated String

mine took no more than like 10 seconds on part 2

HyperNeutrino

5:42 AM

@RedwolfPrograms do you cache the relevant positions that each seat needs to watch

ASCII-only

im dumb but it took 2 seconds to run

@HyperNeutrino no need bro

Unrelated String

and that wasn't with remembering the locations of the visible seats

ASCII-only

that's overkill wth

HyperNeutrino

oh okay

mine takes 2 seconds lol

ASCII-only

mine takes 2 seconds with no special handling

Unrelated String

5:43 AM

i should have cached the positions lmao

HyperNeutrino

wait then how do you do it

Redwolf Programs

Maybe I shouldn't have stored mine as a string and split it each time I wanted a part of it

HyperNeutrino

the way i'm doing it whether or not i save the positions with a first-pass doesn't change how long it takes to code

uh...

Redwolf Programs

I got both right first try though, after like 15 minutes each of debugging and running

Unrelated String

lol

Redwolf Programs

5:44 AM

Wait make that 30 and 15

smh my head

@RedwolfPrograms don't split it just keep it split bruh

charcoal would've been easy

as a list of strings

Redwolf Programs

I know, I was just trying to write the code fast :p

ASCII-only

bruh smh

5:45 AM

@ASCII-only pretty sure that's there in the docs

1st one was easy with window

2nd one is pain with window smh

Unrelated String

i can imagine

ASCII-only

@Razetime yea im just kinda dumb forgot it took in two arguments

what's window :o

Unrelated String

you know, i was almost going to hijack my jelly game of life code until i realized there were three cell types lmao

Razetime

There may actually be a way to get the diagonals easily through stencil

maybe I need to check some docs

@ASCII-only Nifty builtin which does this

ASCII-only

:o that's cheating

Razetime

5:50 AM

pretty much lol

HyperNeutrino

wait that's op xD

i was actually hoping to get a lot higher than part 1 how are people so fast :c

Redwolf Programs

At least I got top 2500 :p

ASCII-only

same

Redwolf Programs

Actually there's still less than 2500 people completed

no chalk today :(

well im playing on redwolf's server

Bubbler

Why am I getting 33 seats with the example for part 2

Lyxal

@RedwolfPrograms get on mc

Redwolf Programs

@Lyxal Can't, it's super late here and I'm about to go to bed :/

Lyxal

6:07 AM

aw ok

coolio

Redwolf Programs

You can still play if you want

ASCII-only

@Bubbler maybe you're not stopping at first seat (whether empty or filled)?

Bubbler

Frick, I messed up x and y coordinates and was pairing a seat at (x,y) with the count at (y,x)

A mistake which would never happen in other language

@Lyxal downloading mc on artix... clearly this is going to end well

Lyxal

@ASCII-only clearly

Unrelated String

7:16 AM

@Bubbler nah it's hard sometimes to remember if 2d array indexing is inverted so row-major arrays are accessed as a[x][y] instead of a[y][x], because I know there's some language that does that but I can never remember which

HyperNeutrino

i always use a[r][c] and usually it helps me make sure i don't get it backwards

Unrelated String

mm

Bubbler

@UnrelatedString At least an indexing would be consistent inside a single language, e.g. if you access one matrix with a[x][y], you'd not access another matrix with b[y][x], whether row-major or column-major

Unrelated String

@Bubbler does factor...

oh no

Bubbler

7:31 AM

Factor doesn't have that syntax at all, but at least I was doing the item access correctly (though I could mess them up while moving around the stack items)

Unrelated String

so your issue was really just that it was hard to keep in order when using the stack

makes sense

Bubbler

and it was not the issue, the real issue was that I forgot to call transpose in one place

Unrelated String

ah

Bubbler

I... really need to implement APL primitives in Factor

Q: Follow a linked list

For this challenge, a linked list looks like this: [1, 2, 4, 0, 6, 1, 3, 1] You'll notice there's no data; each item in the list is just a reference to the index of the next one. Your task is to write a program or function which will follow a linked list like this forever, outputting each item a...

Razetime

@RedwolfPrograms most infinite output stuff falls within sequence , right

Redwolf Programs

Not necessarily, just search "infinite output is:q" to see what I mean

Razetime

maybe it makes sense

caird coinheringaahing

3:22 PM

@RedwolfPrograms You need quotes around the "infinite output". Without them, you get any questions that have both the words "infinite" and "output" (130 ish). With them, you get 14 results

Redwolf Programs

I know, that was just to show that there are at least a few other questions where the tag makes sense, and I'm sure there are plenty others that don't specifically include both words.

caird coinheringaahing

10 if ignoring sequence, and further investigation shows that only 6 of those are open and require infinite output (rather than banning it). It doesn't seem like its a necessary tag, or that it really adds anything extra to tagging that simply including the phrase "infinite output" wouldn't do

Redwolf Programs

I disagree; many questions involving infinite output won't necessarily include the phrase "infinite output". I think it could be useful to be able to search the infinite-output tag, and even if it won't get more than ten or twenty questions, it could still be helpful (we have tags for certain programming languages that only have a few questions)

caird coinheringaahing

@RedwolfPrograms You could open a meta question on it

(and I'm against the language tags, don't think it's useful having a bunch of tags for languages that only have a tips page)

Redwolf Programs

I'll work on a meta post

Any thoughts on the title?

user

That makes sense.

Is the call for categories also done then (or the end of December)?

caird coinheringaahing

user

Cool, thanks

caird coinheringaahing

6:41 PM

@RedwolfPrograms Thought: infinite-output may be too specific. non-halting or something that implies that programs shouldn't finish might be better, as we have a lot more of those

For example, answers to this shouldn't ever halt (theoretically of course), but wouldn't exactly have "infinite output"

Redwolf Programs

Hmm, true. Maybe post an answer to the proposal suggesting it so people can vote.

caird coinheringaahing

Suggestions for a tag name? non-halting doesn't sounds good to me

Redwolf Programs

Not sure, maybe infinite-loop?

John Dvorak

Rust and Haskell call them diverging

Redwolf Programs

runs-forever?

caird coinheringaahing

6:48 PM

That's even worse than non-halting :P I think I'll go with infinite-loop, but I'll include "gimme suggestions" in my answer

Redwolf Programs

Probably the best choice for now

Can tags be renamed, or just deleted and a new one made?

John Dvorak

infinite-loop excludes functions that deadlock on mutexes, IO, ...

endless-runtime?

caird coinheringaahing

@RedwolfPrograms IIRC you can't rename a tag, but there are multiple different options to get rid of it

@JohnDvorak I like that

Redwolf Programs

energizer-bunny :p

(or duracell if you're outside the US)

John Dvorak

@RedwolfPrograms I'll allow it if you can manage to line up a sponsorship.

caird coinheringaahing

6:52 PM

The easiest way to delete a tag is to edit it out of all questions it's currently on and the system deletes it automatically at the end of the month

Other ways are to suggest a synonym, or flag it as needing to be mod-nuked (for rude tags)

Redwolf Programs

How about a compromise, infinite-runtime?

caird coinheringaahing

@RedwolfPrograms Given that it looks like this has a pretty solid consensus (+7/0 vs +1/0), would you mind accepting my answer?

Redwolf Programs

@cairdcoinheringaahing Done

caird coinheringaahing

I'll be home in an hour, anyone planning on being on the server?

Lyxal

Probably yes

@cairdcoinheringaahing well program execution runs for an indefinite amount of time

As compared to something like Hello world, which is definite in time

caird coinheringaahing

@Lyxal It's not a bad suggestion, it's just not as descriptive as infinite-runtime for example

Especially as indefinite can mean vague/undefined, which might not be a good tag for new users to accidently use
