And that there may be other reasonable ways of defining errors for our purpose

Bubbler

s/there's no meta consensus/there's no meta consensus you could find/

There's always a possibility that e.g. caird can give you one

and saying 'error' without further specification is considered unclear

hyper-neutrino

oh yeah redwolf is on vacation still

i was wonder what you were doing up at this hour

Redwolf Programs

"vacation" :p

Bubbler

@AviFS You can always post a meta question though. It'll just be closed as dupe in the worst case

Redwolf Programs

@hyper-neutrino I was going to do a recurring event, but we'd need 6 of them due to the scheduling rules we decided on, and that would complicate a lot of stuff

AviFS

8:06 AM

@Bubbler Certainly, I was letting people know in case someone else would do it

Not familiar with the meta format, and don't particularly want to rn

Bubbler

@AviFS Don't wait for someone else to do it. Just write a question

There's no particular format for meta

Razetime

and meta doesn't mess with rep

StackMeter

@hyper-neutrino by my clock it's 9:07

AviFS

@Bubbler True, but it wasn't in the first multiple pages of searching "error" and other variants. So other people are unlikely to find it as well. It bodes badly

Bubbler

You can just ask anything, as long as it's about the site

hyper-neutrino

8:08 AM

@StackMeter it's 4:08 here so it's 3:08 in texas and redwolf is never up that late, but in hawaii it's...

10:08 PM

AviFS

I can write it up tomorrow, then

Adám

@hyper-neutrino What are you doing up as such an hour‽

hyper-neutrino

uh.

lyxal

CMC: return the first truthy element of a list

AviFS

@Bubbler Defaults are good. Often people don't clarify. For instance, the error-on-odds challenge doesn't have anyone accusing them of being unclear, and they haven't defined anything

hyper-neutrino

8:10 AM

idk how i manage to sleep so little ¯\_(ツ)_/¯ i am tired when i wake up ofc but i am completely fine most of the day especially once it's later in the night

Adám

@lyxal Are we guaranteed there'll be one?

Unrelated String

@lyxal Jelly, 2 bytes: o/

i think

lyxal

@Adám yes

Unrelated String

will test in a minute lmao

Adám

@lyxal APL: 1 (don't need the input)

Redwolf Programs

8:11 AM

@lyxal d=>d.find(x=>x)

hyper-neutrino

wait is 1 the only truthy number

no

(in APL)

idk then

Yes, and 0 is the only falsey one.

AviFS

8:12 AM

@Adám I'm figuring he means to use 0 as falsy, everything else as truthy

hyper-neutrino

huh.

AviFS

Or did you mean to have it be language dependent @lyxal?

Adám

@AviFS If so, it'd be "first non-zero"

hyper-neutrino

{(⍵~0)[1]} if first non-zero

Adám

@hyper-neutrino ⊃~∘0

Razetime

8:13 AM

husk has a 2 byter

AviFS

@Adám wow

Redwolf Programs

I think Ḥ would be an Ash one byter

StackMeter

@hyper-neutrino redwolf goes to sleep at 3pm?

Razetime

whatsat do

hyper-neutrino

@StackMeter ... AM

Redwolf Programs

8:15 AM

lol

Razetime

@RedwolfPrograms explainnnn

Adám

CMC: Non-negative integer list → index of first non-zero.

Redwolf Programs

@Razetime It's just the find function

I forgot whether the default function it used was identity or not

StackMeter

@hyper-neutrino that makes more sense

Razetime

@Adám ⊃⍸∘×

Redwolf Programs

8:17 AM

Midnight is typically when I go to sleep, although being five hours off for a week is going to frick that up I think

Adám

@Razetime ⊃⍸

Razetime

you didn't say list of booleans

Adám

Indeed. Try it.

Razetime

huh

StackMeter

@Adám Python: for i in range(len(l)):if l[i];print(i)

Razetime

8:18 AM

oh alright i get it

StackMeter

done that

Adám

You can't do if l[i];?

StackMeter

@Adám oh it's non-negative

hyper-neutrino

@StackMeter if it weren't, your solution would be wrong and adam's would be correct...

@Adám lambda a:[i for i,e in enumerate(a)if e][0]

Adám

@StackMeter What happens if there are multiple truthies?

hyper-neutrino

8:20 AM

also that's a snippet

StackMeter

oh it's specfically the first one

hyper-neutrino

TḢ in Jelly

literally just "truthy indices => head"

StackMeter

Python snippet: for i in range(len(l)): if l[i];print(i);break

hyper-neutrino

you should probably multiline codeblock that

Adám

Anything better than L=>L.map(x=>x?1:0).indexOf(1) in JS?

StackMeter

8:22 AM

ofc Jelly has a two-byter

it's just the way of things

Redwolf Programs

@Adám findIndex

Adám

@hyper-neutrino Same as in APL, then.

hyper-neutrino

nice

Redwolf Programs

^ Porbably a dupe

Adám

8:26 AM

@RedwolfPrograms So L=>L.findIndex(x=>x)?

Redwolf Programs

Yep

hyper-neutrino

well i almost just gave myself a heart attack

tried to upvote a comment and misclicked flag

ofc there are still a bunch more steps before actually flagging but still I am never sure what is undoable and what requires confirmation and i am always scared of misclicking or leaking things in screenshots

Adám

@RedwolfPrograms "reverse"?

@hyper-neutrino Same.

hyper-neutrino

fun fact: refreshing a user profile requires confirmation, but suspending a user from chat does not, and the buttons are right next to each other (vertically)...

Adám

Yay, SE chat.

8:28 AM

@hyper-neutrino misclicks

Redwolf Programs

@Adám Mirroring horizontablly

hyper-neutrino

move/delete messages and delete room are also right on top of one another

Adám

@RedwolfPrograms How about flipping the output upside down, and/or transposing it?

hyper-neutrino

fortunately delete room requires confirmation but a single accidental space bar hit and the room is gone

Redwolf Programs

@Adám Not allowed

Maybe I'll just disallow reversing it

PyGamer0

8:30 AM

@hyper-neutrino accidentaly clicks & presses spacebar

AviFS

Looks great! Just one suggestion. There's a sentence intended to give a taste of what he have, and which could also serve as ideas for new posters.
> We host coding challenges, such as code golf, and related questions, such as code-golfing tips.
However, the first sentence is already:
> Welcome to Code Golf & Coding Challenges Stack Exchange!
Not to mention both code golf and coding challenges are in our name & logo. It'd be nice to use that sentence to give them other ideas and a broader sense of what we have to offer, and what they might have to offer us.

I'm purposely not including [tag:popularity-contests], [tag:code-bowling], [tag:busy-beaver], [tag:code-shuffleboard], [tag:duct-tape-coding] or [tag:obfuscation], since those are harder to do well, and so not ideal to recommend to newcomers. We might want a separate meta question to collect tags people want to recommend to newcomers?

Also, I'd replace the code-golfing tips example. They'll definitely see them quickly, and they're not really the core of our site. There's one tips per language, so it's not something they can hop onto. And while it is educational/helpful, it's moreso later o…

blah blahking-of-the-hill blah blah

hmmm.... why'd that not work in the text?

hyper-neutrino

multiline messages do not support markdown at all

AviFS

What counts as multiline?

hyper-neutrino

has multiple lines

Adám

@RedwolfPrograms Can we take 1-based integers instead?

Razetime

8:32 AM

shift+enter anywhere

Redwolf Programs

@Adám Sure, will clarify

AviFS

@Razetime Ouch, I see. thanks

hyper-neutrino

yeah basically if it contains newlines

you can turn them into fixed font / code block messages and that's it

also chat.stackexchange.com/rooms/1/sandbox if you want to play around with markdown

i advise against it though, for health and safety reasons

Redwolf Programs

Chat markdown is so awful I feel like it was done on purpose

hyper-neutrino

oh if you think SE code block formatting is stupid try figuring out how discord's works

AviFS

8:34 AM

It's really terrible... I don't get it

hyper-neutrino

nobody does

Redwolf Programs

"I don't get it" is the unofficial motto of SE chat :p

AviFS

hahaha

Well it's pretty impossible to read

PyGamer0

@hyper-neutrino ? isnt it triple backticks

AviFS

So at risk of annoying everyone, I'm going to repost and take up half the wall

@cairdcoinheringaahing Looks great! Just one suggestion. There's a sentence intended to give a taste of what he have, and which could also serve as ideas for new posters.

Not to mention both code golf and coding challenges are in our name & logo. It'd be nice to use that sentence to give them other ideas and a broader sense of what we have to offer, and what they might have to offer us.

I'm open for ideas, but I'm thinking to use "fun", diverse, not-immediately-obvious and underrepresented examples. Tags that will take them to corners of the site they might not find immediately. Things like king-of-the-hill, cops-and-robbers, metagolf & answer-chaining. (Any other ideas?)

I'm purposely not including popularity-contests, code-bowling, busy-beaver, code-shuffleboard, duct-tape-coding or obfuscation, since those are harder to do well, and so not ideal to recommend to newcomers. We might want a separate meta question to collect tags people want to recommend to newcomers?

There's one tips per language, so it's not something they can hop onto. And while it is educational/helpful, it's moreso later on in the golfing career at which point they'll stumble across it. It's not so interesting at the start. This point may be more controversial, though.

@hyper-neutrino ok wow stop make a challenge for this

Razetime

@Adám mans really wants to to ⍉∘↑⌽⍤↑∘'X'¨

Redwolf Programs

@AviFS Doesn't seem like the actual ask question page would be a good spot for that

hyper-neutrino

@hyper-neutrino I use zero width spaces to mess with the backtick formatting
