Gabriel's Horn From Wikipedia, Gabriel's Horn is a particular geometric figure that has infinite surface area but finite volume. I discovered this definition in this Vsauce's video (starting at 0:22) where I took the inspiration for this problem. You begin with a cake (a cuboid) of dimension \$x ...

ಠ_ಠ M doesn't have support for random numbers

hyper-neutrino

00:45

wondering if I should CW the M answer

it feels unethical getting rep off of it but more trivial answers are everywhere so...

caird coinheringaahing

I get that, but CW isnt a rep waiver

hyper-neutrino

yeah you're right. and i think i've commented that elsewhere before. so best to practice what i preach :p

oh well once i get to the front page of rep / to a spot i like i'll probably start bountying off a good amount of rep

caird coinheringaahing

I keep trying to do that, but no one snaps at my deadlineless bounties :/

@hyper-neutrino You're 6 repcaps away from the front page :P

hyper-neutrino

alternatively i could just get rep. idk how i feel about reputation. at the same time internet numbers make me feel good about the time i ~~waste~~ spend on cgcc, but I also don't need reputation at all

i also somewhat feel like pursuing reputation is wrong or bad tho. idk what made me start feeling that way but it contradicts me wanting internet points so... D:

caird coinheringaahing

Personally, I hold the view that pursuing rep for the sake of rep (e.g. to say "look, I have X rep") is generally not great. But, trying to get rep so that you can help moderate the site (not relevant for you), or trying to post good quality posts and "happening" to get rep from it? Either of those are golden in my book

user

00:53

To some extent, most of us are pursuing rep for the sake of rep. If SE weren't gamified, I'm sure there'd be a lot less participation

Q: Exact generalised harmonic numbers

The generalised harmonic number of order \$m\$ of \$n\$ is $$H_{n,m} = \sum_{k=1}^n \frac 1 {k^m}$$ For example, the harmonic numbers are \$H_{n,1}\$, and \$H_{\infty,2} = \frac {\pi^2} 6\$. These are related to the Riemann zeta function as $$\zeta(m) = \lim_{n \to \infty} H_{n,m}$$ Given two pos...

caird coinheringaahing

Which is why I've been unhappy with my recent posts; I no longer "need" rep to be able to help moderate more, so I should aim to be posting high quality, and let people who need to the rep go for the FGITWs/low hanging fruit challenges. Yet, I don't think I've posted a challenge or answer I'm proud of in months

user

I haven't seen a ton of your recent answers, but your challenges are almost always interesting

caird coinheringaahing

Hmm. Most of them are "Here's a sequence I found. Golf it", which are fine, I guess

I think this was my last challenge I actually like :/

user

¯\_(ツ)_/¯ keeps activity up and gives people questions to answer

@cairdcoinheringaahing And Bubbler broke it :P

caird coinheringaahing

00:57

@user I'm fine with that :P

"Breaking" a challenge suggests that there's a nice trick that someone found (via brute forcing or insight or whatever) which is 1000x more interesting than "Implements the formula in the question/user's formula/whatever"

OldSandboxPosts

Sandbox posts last active a week ago: Reveal by Halves (in need of a better name), Complete the Square (UNFINISHED), How Many Students are in our clubs?, A general-purpose macrogenerator

user

I disagree. "Implements user's formula" sounds very interesting :P

People finding a nice trick usually ends up in that trick being ported everywhere and the fun being ruined, even if that trick is amazing. I prefer questions where such mathematical insights can't be made and brute force can't be used to trivialize the task

caird coinheringaahing

TBH I kinda find code-golf "boring". It's fun to write a challenge/answer, do a bit of golf and be done with it, but once it's done, it's done. Non-code-golf challenges are the ones that are usually more interesting, and have a better "legacy". If I look back at my favourite challenges (of mine), most of them are non-code-golf

Bubbler

I like mathematical insights. I like weird base conversion tricks. But my absolute favorite is breaking a challenge :P

caird coinheringaahing

@cairdcoinheringaahing That's probably why I've switched to the more "behind the scenes" stuff (reviewing, tag wikis, edited etc.) rather than posting a lot

hyper-neutrino

01:11

@cairdcoinheringaahing yeah, I agree with that. I guess part of it may be a) I have 25k b) I'm a mod so I shouldn't be going after rep at all, and it's better for others to have it. But at the same time, it's not really like rep I gain is rep others lose either (though I was considering not editing my posts into the LOTM or asking to decline the bounty)

that's why ideally i like to answer challenges that don't take up too much of my time to optimize but also aren't too easy

though the last answer i can think of that i was like exceptionally proud of was honestly probably one of the OEIS chain ones, the rest just ranged from trivial to somewhat interesting :p

caird coinheringaahing

TBF that answer in the OEIS was crazy impressive :D

I can't think of any other answer on the site where someone contacted the person who made whatever the challenge was about in order to solve it :P

hyper-neutrino

was totally worth the time and trouble, lmao

@Ausername i don't think i've seen/reviewed that

A username

vscode works with anything but Java.

@hyper-neutrino Wait wrong answer, I meant this

hyper-neutrino

wait if you get previous moves, can't you just look through all of the previous results and ignore the storage?

also, does the game end when all cards are gone and most points win? seems like the obvious way but just to be sure

A username

You only get the previous moves up to your last move, not full history.

So you get the actions+results of all moves up to and including your previous move.

Will clarify.

Yes you're right about how to win.

hyper-neutrino

05:57

oh so you only get your move and not other bots' moves? or what do you mean

A username

The bots go in a predetermined order, so you get the most recent move of every bot.

hyper-neutrino

oh wait, when you say up to, do you mean in reverse chronological order?

"up to your last move" sounds like [1 .. last] not [last .. now]

A username

Yes, pretty much, but I've clarified it all again just to be sure.

hyper-neutrino

yep, that makes more sense

A username

Ok thanks. I'll start working on the controller now and maybe post tomorrow.

I had a look at your one. Seems pretty good, just can you clarify how the output format works?

hyper-neutrino

06:08

@Ausername it's basically a list of sublists of people - each person should be in exactly one sublist (except if you exclude non-suspicious people), everyone within a sublist should have the same suspicion level, and the sublists should be sorted in decreasing suspicion

(already posted to main btw) i'll try to clarify more in the post but i'm not sure i can make it too much clearer; it's a bit confusing but also straightforward, just that it might not make sense in the middle

ah yes, thank you VS code for not pointing out the 11 missing semicolons in my file \s

How do I know there's 11? Because they all came up as compilation errors

Bubbler

Are you sure the "missing semicolon" errors are actually missing semicolons and not something else?

lyxal

error: ';' expected

it literally is just a case of not recognising errors

Bubbler

I mean, the actual fix may not be it even when the compiler says so

lyxal

but the semicolons actually were missing

Bubbler

OK then

@cairdcoinheringaahing you got to review both the first posts and late answers on the same post

i only got to review one of the two

cuz my delete is binding. sad moment.

caird coinheringaahing

@hyper-neutrino And the VLQ :P

hyper-neutrino

i can delete stuff from VLQ after it's been deleted and it counts as another review task

but i can't get all three off of one post :p

caird coinheringaahing

Well this comment is from the VLQ review :P

I think I downvoted on the First Posts one, and you can't VTD from the Late Answers queue, so I just did nothing

hyper-neutrino

oh yeah i could've just downvoted or commented or smth on one to get both :p

but like, reviewing an answer like that and not deleting it is... the wrong action

and i'd rather do the reviews the way i'm supposed to :p

We are one of 34 sites where SE will be running a trial for their new Community Ads and Hot Network Ads, beginning near the end of the year

user

Can't tell if this'll be a good thing or an okay thing or an annoying thing

Redwolf Programs

Good thing IMO

caird coinheringaahing

The community ads will be (I think) the same as the current one, the "Hot Network Question Ads" are the new thing

> Oh, I'm in agreement with regards to these needing to be manually curated rather than algorithmically picked

user

Community Ads sound good, Open Source ads sound good but won't make it here, but Hot Network Question Ads might just be distracting

Redwolf Programs

If we get to choose them it'd be nice advertising

caird coinheringaahing

14:03

So it looks like we'll be able to select a few "perfect" questions (similar to the Tour) that we can use as examples for newer users

user

Aren't HNQs usually problematic for us though? The xkcd one got a lot of new users (not a bad thing at all, but we might get flooded with low quality posts)

Redwolf Programs

I think it'll be chosen by mods though

It's unrelated to the actual HNQs if I'm reading it right

caird coinheringaahing

JNat's basically said that "we" will be able to choose the questions. Whether that's having a post like the community-ads post, where we post suggestions, or if the mods/CMs get to decide is unknown

user

Ah, that sounds a lot better

caird coinheringaahing

@cairdcoinheringaahing ಠ_ಠ Because I didn't pin this, I can't star it

hyper-neutrino

14:06

in any case, JNat did confirm that they agree that automatic selection won't work

Redwolf Programs

I'll unpin so you can pin it then :p

caird coinheringaahing

Nah, it's fine :P

hyper-neutrino

we really don't want the HNQ effect on something even more noticeable / visible than HNQ itself :p

Redwolf Programs

But if we get to choose the challenge, that's much different

Other than the upvote issues

hyper-neutrino

yeah. like caird said idk if it'll be a vote or if we can just select one like with tour page. if it's like the latter hopefully we'll actually be allowed to select any challenge, not just a limited subset

Redwolf Programs

I think the length requirements wouldn't be necessary, so there shouldn't be any limited subsets needed :p

Honestly I would love to have that historical locked though

It's not a correct use of the site, but neither is CGCC

user

Why? It has nothing to do with code golf

hyper-neutrino

I agree with Dennis on this

caird coinheringaahing

If the memes page gets deleted, then that gets deleted

user

@RedwolfPrograms CGCC isn't a correct use of this network, but since this site specifically says it's about recreational programming and not juicing advacados, I don't see why it needs to stay

Redwolf Programs

I know it's the correct answer, I just don't like that it is :p

hyper-neutrino

14:15

it doesn't have historical significance, even if memes were still around, and the previous mod team deleted the memes unanimously, and if I called the other mods to vote on it, I think we'd also unanimously agree with that :P

user

@RedwolfPrograms That's not the correct answer, this is :P

Redwolf Programs

No way

I actually did recover my old datapack

It's just spread out across thousands of files, most of which are junk

Wzl

is there a way (short of SEDE) to see the exact view count of a question?

Redwolf Programs

Yes

Hover over it

Or use question reception userscript

caird coinheringaahing

@Wzl As Redwolf said, hover your mouse over the number in the "Viewed: N times" and it should give you the exact number

There's no way to do it (short of SEDE) on mobile or the apps tho

Interestingly, it seems as though mod-agreement-policy is not only a red tag, but is also a MM-only red tag (and the only MM-only red tag)

I can't imagine why any site other than MM would need product-discovery, yet I think all sites on the network have it

Wasif

@RedwolfPrograms he said for any sentence IMO

Redwolf Programs

Redwolf Programs

What if upvotes were like a clicker game

You can click faster or for longer to give them more rep

Getting more rep lets you upgrade how good your clicks are

or buy things to automate clicking on people's upvote (or downvote) buttons

Wzl

it is definitely a serious question (but not "definitely a serious question"):<

hyper-neutrino

@RedwolfPrograms that just sounds like voting rings with extra steps

Redwolf Programs

Every click would be worth significantly less obviously

user

@hyper-neutrino Well fewer steps for the voting rings - it's easy to upgrade

Redwolf Programs

Eventually they'd converge into one conveniently bannable account

Or you could just silently revert the upvotes

ok that's probably better

Redwolf Programs

Actually no that seems like it'd be really wasteful of bandwidth

Unless you cached clicks and sent the number per second, but that would be super easy to cheat

CMC: Given a string, return its prefixes

hyper-neutrino

jelly, 1P but the 1 is superscript and the P is that fancy looking P

caird coinheringaahing

Jelly has a 1 byte solution :P

Redwolf Programs

Ash would have been !

hyper-neutrino

ah Ä

that gives python-strings though right? which breaks everything after it

caird coinheringaahing

¯\_(ツ)_/¯

A stupid way to get a list of 1s equal to the length of the string input :P

user

@cairdcoinheringaahing Scala: _.inits :)

@cairdcoinheringaahing What's that? Compare to itself?

caird coinheringaahing

Prefixes, then length of each

@cairdcoinheringaahing J, 2 bytes, ]\

Oh, ~~that really is stupid~~

Ugh Ubuntu does this awful thing where if you double tap the touchpad it'll start highlighting or dragging stuff

APL: ,\

@Wzl it's a shame \ on its own doesn't work as that's basically 'apply identity function to each prefix'

Wzl

CMC: Length of each of the prefixes :)

@rak1507 *agrees*

J :P in Jelly

What's an easy way to get the suffixes of a vector in APL? ⌽¨,\⌽foo?

rak1507

yeah, it's basically ,\ under reverse

user

@Wzl ⍳≢

Wish APL had scanl and foldl

rak1507

oh right

@user same

if the string is unique you can do ⍋⍨↓¨⊂

which is fun I guess
