On PPCG, do you flag an answer if it in no way answers the question?

Step Hen

3:48 PM

@musicman523 Yes, flag it for deletion as not an answer

musicman523

@StepHen The help text on "Not an answer" says

This was posted as an answer, but it does not attempt to answer the question. It should possibly be an edit, a comment, another question, or deleted altogether.

In my mind this means it would be something like not even an attempt to answer the question, like not even code at all

This is the answer in question if you wanted to look

Wheat Wizard

@musicman523 Flag it with a custom flag not "not an answer"

musicman523

@WheatWizard That was my plan but I wanted to make sure that it should be flagged first. Thank you!

Flagged? Yes. Downvoted to -5 before the user even got to read the first comment? Maybe not.

Q: Make a Quiz Parser

Your task is to create a program that will take an input of multiple 4-choice questions (A, B, C, D) in the format shown below, display each question (format also shown below) and its 4 answer choices, get the user's answer to each question, and, at the end of the quiz, output their score as a pe...

codegolf.meta.stackexchange.com/questions/2447/… Hmm

Not that I go on meta that often, but that's the first meta consensus I've read that's ever made me feel icky

Not because it doesn't make sense for languages where it's necessary (like Haskell)

alright i added stuff

Fibtraction - Fibonacci with subtraction Introduction The Fibtraction (as I call it) sequence is the Fibonacci challenge but instead of adding numbers, you subtract them. The first few numbers of this challenge are: 1, 2, -1, 3, -4, 7, -11, 18, -29, 47, -76, 123, -199, 322, -521, 843, -1364.....

But because you get answers like this for languages that aren't meant for currying in

yeah, but trying to "allow it in one language" is a rather bad idea

Dennis

4:40 PM

Currying in Java may be a bit unorthodox, but that's hardly the worst practice encouraged by code golf.

^

I know it's a bad idea

To limit it

I'm not disagreeing with it, I'm just saying it looks gross.

the real problem is that the types are implied, but I've been outvoted on that

I was gonna say

There's already enough ire for untyped lambdas

I mean, I can golf off 20 bytes off of that code by picking a different input type

4:44 PM

Oh? Which one?

IntList from eclipse collections

That's bringing in an external library, is it not?

well, yeah. But you don't need to import it because its the input type

But you do have to have it as part of the project.

true, but that doesn't affect the byte count

4:46 PM

It affects which language you submit it as.

As far as I understand, anyways

no, it doesn't. We allow other libraries in the same language

I was just editing it :)

You can't just write import things.stuff.IntList and have it work

or whatever the path is

DJMcMayhem

4:49 PM

@cairdcoinheringaahing That's.... A terrible idea. I'm sorry, but no

I don't think a challenge saying go break the rules on a different challenge is a good idea

So no, I wouldn't consider Java + Eclipse Collection to be the same as just Java

Q: Is a code golfing library legitimate?

My read on the current state of meta.CG opinion is that the use of libraries is acceptable and that the library call should count in the character count: Use of built-in functions and libraries in Code Golfs Using libraries in solutions And from this discussion I conclude that there isn't real...

@Dennis can we reverse the duplicate-ness?

@Xanderhall anyways, the top answer on the first post, indicates that it is the same language

just that it needs to be included in the header

@NathanMerrill That's what I said, just not in the right way obviously.

Erik the Outgolfer

maybe close the other as a duplicate

You'd have to submit the answer as Java + Eclipse Collections

4:59 PM

@Xanderhall then we're just talking semantics, because I thought by saying "to be the same" you were meaning the "same language"

@NewSandboxedPosts a bit late

that was not that delayed :)

I love this answer

"This whole thing will turn into 'Who can write the best library'"

5:00 PM

right, but it's already turned into "who can write the best language"

Exactly

That's my point

i think somebody's already done that :P

Also, there's already a standard loophole about 'limited' languages

Does this site support environments in the first place?

Yes

But then it randomly started borking

awesome. the preview catched the short moment where the vote count was -1.

@LegionMammal978 yep, but sadly the bot catched exactly the wrong moment :(

How do the golf-langs tend to do with three or more inputs?

command line args

Oh, forgot about that.

PhiNotPi

thank you autocomplete

that's... um... what?

assuming the editor is basing that off strings used before, why were those strings used before?

PhiNotPi

I have no idea where those strings are from.

mınxomaτ

Looks like a key. Calculate the entropy and we'll know if it's compressed / crypto data or some encoded blob.

@mınxomaτ You said that you deal with huge quantities of data daily

How huge?

I kinda forgot

mınxomaτ

Depends.

orlp

@Lembik can you recognize the algorithm? :)

@mınxomaτ Also, to answer your question from earlier, I don't appear to have been accepted to the 16-qubit beta test.

@orlp not yet :) Well it looks familiar

but it's very fast!

7:25 PM

@Mendeleev did you still have a question about cisco equipment?

@ThomasWard Yeah

I have a 3602i access point running IOS

It keeps dropping its Gigabit Ethernet connection

I have logs of it and everything, do you know anything about these?

is it jacked into an ASA or some other equipment?

Please define ASA.

orlp

@Lembik I did take some shortcuts, not the full computation is reduced, so it slows down for bigger inputs

It's connected to an unmanaged switch. I have a WLC on the network

7:27 PM

@Mendeleev ASA is the Adaptive SEcurity Appliance. Usually Cisco backed networks are CISCO firewalls.

@Mendeleev expandAcronym("WLC");

@orlp but not by much!

tuskiomi

@WheatWizard are you here?

@orlp there was soooo much complaining about the time limit

@ThomasWard This isn't actually a Cisco network. It's my home network. The router/firewall is pfSense in a VM :P

@ThomasWard Wireless Controller

ah

7:28 PM

It's supposed to coordinate my APs.

It works pretty well with the two 3602e's I have, but not the one 3602i

@Mendeleev I'd check the connection between the wireless controller and the access point, your controller should have more than one NIC.

@ThomasWard It's a VM

@Mendeleev I don't know much about Cisco access points, unfortunately, we just switched to Ubiquity access points here.

It's the virtual WLC

@Mendeleev same question - it has a virtual bridge to the physical port doesn't it?

7:29 PM

@ThomasWard I wanted to use those, but my dad has Cisco experience-ish so he decided to go with something he already knows about...

Wheat Wizard

@tuskiomi Yes

orlp

@Lembik you should explicitly mention that it's to prevent bruteforcing

@ThomasWard It's connected to the vSwitch, it also has a virtual service interface that's disconnected (as per the setup guide)

@Mendeleev your dad needs a reality check. It took me twenty minutes max to configure my Ubiquity APs with a cloudkey. CISCO equipment, especially access points, are painful.

@orlp I will do that next time

tuskiomi

7:30 PM

@WheatWizard can you hop over to this chatroom?

@Mendeleev i can't really help as much with the Cisco equipment though, not access points anyways

Wheat Wizard

Already there

sorry :/
