@Bbrk24 Is the ${{ !contains(github.event.head_commit.message, '[skip ci]') }} part supposed to make it not run?

@user That makes it not run if the commit message says “[skip ci]” — so that if I commit before it’s functional, to save my work, I don’t get CI failures

@user Yeah but it’s not running on the tag, it’s running on the branch on a commit that happens to also be tagged

Notice how they're the same commit, but the last one is running on the branch instead of the tag

Q: Is this a powerful number?

A powerful number is a positive integer \$n\$ such that for every prime \$p\$ that divides \$n\$, \$p^2\$ also divides \$n\$. Or equivalently, \$n\$ is powerful if and only if it can be written in the form \$n = a^2b^3\$, where \$a\$ and \$b\$ are positive integers. For example, \$972 = 2^2 \time...

Hey all, is there an exception in Java to the rule that boilerplate code (import, puclic class...) needs to be included in the byte count? I'm asking in relation to this answer

Bbrk24

I'm not sure about imports, but I know you don't need to count the class declaration if your answer is a lambda

flawr

For clarity, maybe include double as an example of a finite data type — Luis Mendo 4 mins ago

@LuisMendo but double has +-Inf, it cannot possibly be finite? :D

Bbrk24

But it is finitely precise

@mousetail thanks for the link, I thought there must have been something similar, but didn't find it in my first round of searching!

Go, 78 bytes func(a,b rune)rune{return[]rune("紫騮靘熏X綠黻紅硅黯碧")[a*b%25%11]} Attempt This Online! Port of @Arnauld's answer.

Dunno Go; what does rune do?

Bbrk24

It's Go's name for char

I think they wanted to use a different name than char because it's a different size than the C type

but C# uses char for a two-byte type so

@DannyuNDos Note that the full expression is []rune("..."), i.e. "use this string literal as a rune array"

Strings by default are sequences of byte, not rune, and byte is too small for those CJK characters

idk the physics behind it, but time has been on some hardcore drugs for the past 18 months

I keep waiting for the drugs to wear off but then it takes another bigger dose of even weirder drugs

@mousetail Every night I walk up to Time in a coat full of bottles and whisper to them “do you want some herohin?” They always accept, and they take the drug immediately. I have not been arrested because this is state-sponsored.

Please stop doing that, I want to have a future :/

mousetail

Is that in any way contraversy on whether LSD is a drug?

The Empty String Photographer

@user Correction: North Korea

Dannyu NDos

North Korea? Nah, they don't prohibit drugs. They permit even drunk driving.

user

@mousetail I think the controversy's about whether it should be considered dangerous, since there's no long-term side effects (?) but you can still hurt yourself/others while you're tripping

Bbrk24

> there's no long-term side effects (?)

I was under the impression that there are

mousetail

The issue is that it's just been insufficently studied

Not in the US, I don't care what the FBI does

Bbrk24

13:31

@mousetail What I had heard specifically was that it can get into your spine where it lies dormant for years until suddenly you're tripping again

mousetail

That could very well be the case

There has been very little study on long term effects

user

@Bbrk24 Doesn't look like the PR I opened worked :(

Bbrk24

Yeah that's what I expected

It might not be fixable automatically, I might just have to add [skip ci] to my release commits

> I meant the git push --atomic origin master 1.4.1 part itself could be done in a workflow.

@user How is a workflow (running on GitHub) supposed to push changes from my computer to GitHub?

user

18:14

The changes wouldn't be on your computer, they'd be automatically generated

I guess it wouldn't be in the exact same format as your current manual changelog, but it'd be good enough

Like github.com/google-github-actions/release-please-action

But tagging the commits with [skip_ci] is probably easiest (or modifying the check in your workflow to match \d\.\d\.\d)

Bbrk24

Oh I see

user

Or maybe you could push your changes only to master, then make the tag?

Or you could make your workflow ignore changes to your changelog

docs.github.com/en/actions/using-workflows/…

Bbrk24

Actually, that's a good point. I should definitely make it only run when the relevant files are changed

@NewPosts Especially with 3/4 of the mods on strike atm, please don't flag posts that regular users can handle. Off-topic and VLQ posts, stuff that's never going to need to be undeleted, can be dealt with by reviewers in the LQP queue and by users with 10k+ and 20k+ rep. If something's still around after a day or two, then raise a flag

Happy?

Simd

@DLosc L = [1, 1.3, 2, 2.5]
I want to iterate over sorted pairs so that each end of the pair fits between two different values in L. In this case an acceptable created list of pairs would be:

[(0.5, 1.2), (0.5, 1.4), (0.5, 2.1), (0.5, 2.6), (1.1, 1.4), (1.1, 2.1), (1.1, 2.6), (1.4, 2.1), (1.4, 2.6), (2.1, 2.6)]

The first element in a pair is allowed to be less than the smallest value in L and the second element in a pair can be larger than the largest value in L as in the example.

I don't mind what the exact values in the pairs are as long as they are not the same as any value in L.

@DLosc Is that clearer?

DLosc

Oh, okay. So you want actual pairs of floats, not just an indicator of which "slots" to use.

Allowing numbers less than the smallest and greater than the largest complicates things significantly.

Can we use +inf as one of the values in the output?

It's a floating point number, technically.

Simd

@DLosc +inf is not allowed :)

just add one to the largest and subtract one from the smallest!

DLosc

19:34

On the large end, yes. On the small end, if the smallest is <= 1, that would make the inserted number non-positive... is that allowed?

Simd

no.. need to find a number between the smallest and 0

DLosc

IMO it would make for a better CMC if it didn't include finding numbers outside the range of the original list. Corner cases are annoying to deal with. But it's your CMC. :)

Simd

@DLosc :)

DLosc

Oh, and: what's the minimum size of input list we need to handle?

Simd

20:02

@DLosc 1

DLosc

Dang, was hoping for 2 :P

Simd

21:23

@DLosc :)

Maybe it should be a challenge on main!?
