an "affair" is a close relationship between two people, closer than friendship and farther than love

Uh, what do I know. I've only gone on two dates (with that first girl), and never had an affair (not planning to either).

Room owners: starring your own message gets you the hat.

Adám

@wizzwizz4 I'm perfectly happy with my top hat (though why doesn't it have a ❄ on it‽)

Erik the Outgolfer

@Adám the top bar doesn't normally contain that symbol (even though last year's request did); however, the real issue is that the symbols are permutated!

Adám

@EriktheOutgolfer Nicely spotted. Btw, the circled question mark is missing too.

El'endia Starman

@EriktheOutgolfer My definition of an affair is a romantic relationship with someone other than your partner and without said partner's consent. I think it is absolutely possible for there to be more love in an affair than in the actual married/dating relationship, though I don't think that makes it morally right.

Adám

Heh, "question" finds ㊷

@Veskah No, but there's more left of '19 to fix it in (I doubt it will happen, though) than of '18.

if anyone here knows scala well enough, is there any shorter equivalent for match{case} with only one case for a regex

well really a shorter way to do regex single match with capture groups as args

so something like JS's string.replace(/(a)(b)/, (m, a, b) => a + ',' + b), except a match not a replace (note that regex and function here are just an example)

also any shorter way to do if(a>"")d=a.toInt

Q: Transitive Equality

The Challenge Your program should take 3 inputs: A positive integer which is the number of variables, A set of unordered pairs of nonnegative integers, where each pair represents an equality between variables, and A positive integer which represents the starting variable, It should return a ...

code-golf graph-theory equation

^ Return the equivalence class of some given element

@Adám Or this where you need to return all the equivalence classes

Adám

11:54 AM

@BMO I meant much simpler than that. Given a Boolean matrix of connections (or a list of indices of connections or a list of connections), add all the connections/endpoints you can get to. [[0,1,0],[1,1,0],[1,0,1]] → [[1,1,0],[1,1,0],[1,1,1]].

BMO

Oh, maybe there is but I can't recall one. Searching only yielded the second challenge I posted

Adám

@BMO Yeah, I also only found those two. However, it could possibly not use the technical term, just saying "Where can I get to?"

Also that technical term can scare off people from an otherwise simple challenge.

BMO

@Adám Yes, unfortunately that happens from time to time. Even with sequence-challenges that don't link to oeis -.-

Adám

@BMO That's not the correct solution, but close ;-)

BMO

@Adám I don't understand?

Oh maybe the challenge is in the graph-theory category maintained by Peter, he does quite a good job in keeping track of such things and recognizing underlying theories, even if not specifically mentioned

Did you check there?

Adám

12:05 PM

@BMO A joke on your -.- which is pretty close to a solution in APL.

BMO

Lol, that short!?

One of these days I will learn APL..

Leaky Nun

@BMO yes, put that down in your resolution list

Adám

@BMO I looked through all graph-theory. Didn't find anything. I'll post.

BMO

@LeakyNun It's quite long already

But it seems like it's worth it, giving another perspective on programming

Adám

@BMO Exactly.

ais523

1:16 PM

this one is close: codegolf.stackexchange.com/questions/76299/…

BMO

@ais523 It's much more difficult though, the one Adám has in mind is basically adj_matrix ↦ adj_matrix^len(adj_matrix) and coerce non-zero entries to 1

ais523

1:32 PM

the core of the problem is the same, isn't it? (many answers start out by solving Adám's problem)

just the output encoding is more complex

BMO

@ais523 Yup, just saying his is easier which would probably mean that it's a dupe

ais523

it's a pity our dupe rules are as they are, and don't allow us to "shuffle around" problems to get the best possible version of each part of the problem

BMO

Could it - in theory - not be changed?

Sometimes it's also weird how the dupe-rules are enforced..

New users' challenges get closed way more often than well established users' which is a shame really.

@BMO (I mean as dupe, if they post unclear challenges that's a different thing)

Adám

1:58 PM

I'm also being very flexible with I/O

Dennis

@BMO Because of bias or because new users do less (if any) dupe checks?

@BMO If someone starts a meta discussion and the community agrees, sure.

ais523

being an experienced user means you're more likely to remember the dupe

and it can be hard to find one any other way

BMO

2:19 PM

@ais523 This user for example found the "dupe" themselves and this too

Yet for most languages I believe the former is more difficult to port than the latter.

ais523

the latter example you linked isn't a case of finding a dupe, but of intentionally creating a challenge based on existing challenges that are doing well

that's something we often discourage, but if you are doing it, it's not surprising you know the existing challenges!

for the former example, it's not obvious to me that the OP knew about the related challenge; maybe they did, but in any case the victory condition is so different that it wouldn't be a dupe anyway

BMO

@ais523 But it's closed?

ais523

@BMO neither of the challenges you linked are closed

ooh, I see

I have low rep

so when you link to a challenge that's closed as duplicate, SE automatically sends me to the challenge it's closed as a duplicate of

talk about misfeatures…

@quartata disgusting — how often to they sanitise the machines?

quartata

well its NYC so im sure the tap water is good

i cant speak to the filtered water

ironic huh, the water you pay for with this is probably more at risk of being contaminated

Adám

@quartata My point exactly. Municipal water is continuously analysed. Commercial water plants probably just rely on "best practices" and occasional random inspections.

pro-tip: if you write software, stop setting /tmp as the default save location. and if you do this, give an option to change the default save location please

not ~/tmp, /tmp

@Riker I always have the default save location be /root/critical/nuclear_launch_codes.txt

Riker

I'm not even certain what is in here anyway

and i do not trust my OS enough to delete those

Veskah

Real pro-tip: Always hardcode it to C:\Windows\Temp\ regardless of supported platforms

Riker

@Mego why root? i save mine under /usr/local/bin/no_russians_allowed/

works great, if you make a script named "launch_nukes" in the parent folder that executes the script in no_russians then you can just launch them ezpz
