Q: Derivative of a product

In calculus, the derivative of a mathematical function defines the rate at which it changes. The derivative of a function f(x) can be marked as f'(x), and these can sometimes be abbreviated to f and f'. The derivative of the product of two functions fg is f'g + g'f. The derivative of three fgh is...

I do love how the site an SE question is asked on drastically changes the meaning of the question :P "How do I replace one character with another?" on SO or SU is very different when asked on RPG.SE :P

From time to time a question hits HNQ because its context-free title is strange.

"I have too many children and I can't kill them fast enough" might be about fork bombs, but that title...

Arqade and this site are usually good candidates for that :P

"How can I tell if a corpse is safe to eat?" is a legit Arqade question

not to interrupt y'all's political miseries, but there's CG politics to consider

Apr 30 at 2:25, by caird coinheringaahing

CMM: What do you think, should we add more ROs? And should the ROs be elected, or just appointed by us existing ROs?

It's been a week

and IIRC that's when it was said it'd be considered again

Apr 30 at 2:51, by caird coinheringaahing

Regardless: I'll leave the pin up for a week or so, then, if we want an election, I'll start a meta thread for nominations a bit after that. If we want a chat election/apppointment from us ROs, then updates will come shortly after

I often forget that this room is on-topic only. On The Side Channel and The DMZ (Crypto.SE and Sec.SE) where I hang out most of the time, it's almost always off-topic.

Alright, joining that room now.

@lyxal Not to spoil anything, but it is currently being considered in a RO/mod room

@forest we pretty much started doing that within the last week or two because there ends up being so much off topic that it drowns out actual on topic conversations

How about a Solaris Zones 0day instead.

@UnrelatedString Yeah I remember. It felt like the average age in this room was 11.

Unrelated String

yeah

caird coinheringaahing

@forest We're a bit of a weird blend between on/off topic, in that off-topic is ok, so long as it stops when on-topic discussion is required/wanted

hyper-neutrino

yeah, and not only was it too off-topic but also just way too noisy; like off-topic conversation can still be meaningful cuz it's not like enough happens on-site that we need to constantly have conversations about CGCC.SE, but when it's so noisy that even off-topic conversations are hard to have then that's an issue

also ^^ which i assume is also how rooms like side channel or DMZ would go if someone needed to discuss on-topic stuff, or at least I hope so

caird coinheringaahing

Plus, for coherent, but off-topic threads, it doesn't hurt to move to a spin off room - not everyone wants to debate the Israel/Palestine situation in the rom for golf discussion

@hyper-neutrino The maturity level in The DMZ is high enough that we don't have many issues there.

Speaking of which, if any of y'all are under 16 and register an account on Crypto.SE, I'll be bound by the mod agreement to report you. So...

caird coinheringaahing

@forest Only if they're based in the EU

If they're in the US, they only have to be 13 or older

@cairdcoinheringaahing Apparently we have to report no matter what.

I asked in TL (mod-only chat) some time ago because I was under the same impression you were: That I only had to report if they were either under 13, or under 16 and in the EU. But apparently anyone under 16 must be reported, but only if they're on a site I'm a mod on. I'm not sure why, but I'm guessing liability reasons.

Aiden Chow

ok guys im under 16 plz dont ban me

caird coinheringaahing

@forest Huh. We've had our fair share of age related mod runins here (HN is on his second account, cause the first was deleted by accident due to age reasons), but I thought it was always "16 if EU, 13 elsewhere"

forest

You won't get banned unless you're also in the EU.

Aiden Chow

01:35

@forest im in US

forest

@cairdcoinheringaahing Yeah that is the rule, but mods have to report to higher ups no matter what.

caird coinheringaahing

@AidenChow As a general rule, I'd avoid mentioning your age no matter what :P

Unrelated String

i'd assume the unconditional report is just so higher staff can make absolutely sure they're not eu

forest

@AidenChow Yeah then you won't get suspended, but I'd still be obligated to report you if you were on my site. Same with other mods on their sites. If you live in the US, then most likely staff would do nothing with the report. That's why it's so weird that mods need to report...

caird coinheringaahing

Technically speaking, HN is now obliged to report you

there's nothing to gain from it

forest

@cairdcoinheringaahing But even still, escalating to CMs is mandatory.

Which is weird because if you know the user isn't in the EU, you know the CMs won't do anything...

So it's just a no-op that's required for... liability purposes, maybe?

Unrelated String

sounds right

caird coinheringaahing

internet + under 18s = super strict laws

Which is totally insane.

Btw, you can just use Tor so various sites don't try to spy on you and censor you.

caird coinheringaahing

@forest IIRc actually, there are a couple of other places that require 16. I think Israel maybe? Mith was very concerned about potentially losing their account if the change applied retroactively

forest

01:39

prolly

The whole "protect the kids" bs that's been going around the internet just makes things work. Hackers and pervs actually do better when kids are forced to congregate together and only interact with each other in secrecy.

And I think the EFF wrote about a new EU law that may require all websites to spy on kids, in the name of "keeping them safe", which will obviously backfire.

totally unrelated to what we are talking about, but: for anyone with experience with ap calc, in the frq's, can u just find the value of a definite integral using numerical methods (i.e. plug into graphing calculator), or do u have to actually compute all integrals ?

I mean, what's unclear about return chain and arities(chain) + [1] < [0, 2] * len(chain)???

hyper-neutrino

that one took me many minutes to even begin to interpret lmao

Who doesn't use Python's obscure list ordering rules as the basic for a key language feature?

And we all know that tokenisation based entirely on regex is the clearest and easiest-to-understand way of tokenising code

Euler characteristic of a binary array code-golf topology geometry array binary-matrix A 2d binary array represents a shape in the plane. 1 means a square at that position. 0 means nothing. The background is 0. For example, the array [[0,1,0],[0,0,1],[1,1,1]] represents the following shape: ...

@cairdcoinheringaahing lexicographic comparison isn't exactly obscure in and of itself, but it's sure as hell the least readable possible way to do that

@RadvylfPrograms how you gonna deal with infinite loops?

I would un ironically support a language with q termination checjer that did this

I like how SE said they'd give updates on the community ads in the first quarter of the year and now we're in Q2 without any new information

Hell, they haven't even done anything about any 2022 Q1 stuff: meta.stackexchange.com/q/378498/391137

Ah

Turns out we're in 2023 Q1

Thanks Prosus

Very cool

As a note, there is no Q2 2022. As part of the Prosus acquisition we've moved to align with their fiscal calendar. We're currently in Q1 of 2023. — Catija ♦ yesterday

i feel like i need to get better geometric intuition for vector math
have apparently shown that a linear support vector machine can perfectly learn xor, which is obviously wrong, but i don't actually know where i went wrong because i have no idea how these dot products have anything to do with the intuitive idea of a separating hyperplane lmao

remembered i have a computer and turns out i just calculated the dot products wrong lmao

Aiden Chow

well whatever u said just flew right over my head lmao

Unrelated String

got the sign wrong on [1, 1] dot [-1, -1] which should have been obvious halfway through the others lmao

and it can't be learned because if i try sending one pair to zero the other pair explodes away from each other

and obviously that is solved by a quadratic kernel

I swear mathematicians gave their findings the most technical and academic sounding names they could think of so that if their parents or friends ever asked what they were doing with their life they could say more than "making numbers go brrr"

I am trying to make a function defined by log n numbers where n is a parameter. The idea is for 0 <= x < n/2, f(x) returns the first number, for x between n/2 and 3n/4 you get the second. Each time the interval halves in length. But I am not sure how to do this. Any ideas?

Does my question make sense?

> separating hyperplane

Are you intentionally trying to confise us?

Unrelated String

by separating hyperplane i mean i can only really reason about a separating line in two dimensions but the concept scales

and fortunately the problem i'm doing is just 2d

the basic idea of an svm is literally just learning a hyperplane that spatially chops your data into the classifications you want

and since that obviously will not work in the majority of cases you can toss a kernel in there

Maybe I will post it as a challenge :)

@RadvylfPrograms falsy result of the condition, unless you already have a short-circuiting AND operator which allows you to write 0 and {...}

Q: Sorting people on a plane

A few days ago I made a puzzle about moving people around on an airplane. Now I am interested in the general version of this puzzle and the shortest code golf for it. I will briefly summarise the puzzle here. A small plane went through some heavy turbulence and all its $N$ passengers ended up in ...

New language uses C# to Transpile to C. This is the right kind of painful.

lyxal

That sounds funky.

too funky

ATaco

Everything I do is funky.

Ideally if I write the Transpiler once I can write it again in the language itself.

Github Co-pilot has been great for me because it convinces me to write comments.

lyxal

coding by prompts is good like that

and the better the prompt, the better the response and the better prompts = better comments = better documentation

ATaco

It's really incredible how effective it is at generating lots of usable code from very little information

Ginger

If I ever get copilot I'm just going to immediately delete the comments after I get the code

lyxal

@ATaco especially since they seem to have added context from other files

I've noticed lately that it draws from other files you have open

and that it didn't do that previously

ATaco

I'm pretty sure it reads my Github

It knows my style pretty damn well

lyxal

that or your style matches patterns within the training data

ATaco

Works for me /shrug

emanresu A

Does seem to copy your coding style

lyxal

> GitHub Copilot relies on file content for context, both in the file you are editing, as well as neighboring or related files. When you are using GitHub Copilot, it may also collect the URLs of repositories or file paths to identify relevant context.

so it might actually look at your repos if need be

CMQ: Do you use closing keywords in PRs on Github?

Imagine using meaningful messages

VTDs?

Closing keywords link the merging of PRs to the closing of issues

CMC make a function defined by log n numbers where n is a parameter. The idea is for 0 <= x < n/2, f(x) returns the first number, for x between n/2 and 3n/4 you get the second. Each time the interval halves in length.
