The Nineteenth Byte

International Standards Proposal: Since open brackets determine the bracket type and the close bracket is unambiguously pairable with an open bracket, have the close bracket be just one bracket type and use the other two close brackets as open brackets so you can have 5 bracket types.

@Riker u is not really an abbreviation by my standards but I guess it counts since you have the other 3 and it's border-line

also, -1 byte: l8r

@HyperNeutrino I mean it's shorter :p

so it does "abbreviate"

@WheatWizard I don't think this is a duplicate of the 6*9=42 challenge... It's related, but you must use very different approaches to solve it (at least in the languages I know). Hammering it after 38 answers, 3k views, and no other duplicate votes seems a bit excessive...?

Just spent a lot of time debugging an UB in Pascal (forget to put return value). (next OEIS) - FP compiler doesn't emit any warning at all.

4 and 5 returns 1 and 2 correctly. 6, after a long time, returns 7.

However it's probably O(n!² × n³) now. Need to reduce to about O(n! × n⁵ log n).

user202729

7:41 AM

Or not. Implementing sort in Pascal is not fun, anyway.
@HyperNeutrino What languages / is there any languages that you are familiar to and is still usable (a.k.a., not used twice) in the OEIS challenge?

Funky still has a use :P

-

@EricTressler ?

ok... just kidding

an unholy taxi + seed + monopoly combination:
taxi for execution - arrive at a place to call the respective function
seed to seed the dice generator
monopoly for route layout

Eric Tressler

would the dice serve any real purpose, or just to make the language terrible

ASCII-only

11:31 AM

roll format is <roll determining number of rolls to move> <n rolls, sum will be used as movement>

dice are really to make it hard to golf

because really any seed giving the right sums will work (it uses two dice btw)

Eric Tressler

but then for long enough programs, depending on the properties of the PRNG, there may be no seed that generates the functions you need

and in particular the language would have a finite number of expressible programs

ASCII-only

hmm I guess that's true

But you could say the same about Seed

plus that can be easily worked around by having modules

HyperNeutrino

HyperNeutrino

1:36 PM

@cairdcoinheringaahing If you're a moderator or room owner, you can click the drop down menu of a message and click "clear stars". There is no way to clear all stars in an entire room as far as I know; that would probably cause a bit of strain on the servers if, say, Dennis decided to clear the stars from all 25572 starred messages in TNB :P

Anonymous

@cairdcoinheringaahing What HN said, but specifically it's the dropdown menu on the message on the starboard. There's a userscript for clearing stars from the transcript that you can find on Mother Meta.

caird coinheringaahing

Thanks, both of you!

HyperNeutrino

@Mego Is it not on the message itself in the main area of the chat window? That's odd...

@HyperNeutrino Probably a bit of a strain, though it would be easy to do. It's just a POST request to /messages/<id>/unstar with your fkey.

Comments on the CNR concept here?

I like the idea, gave it a +1 and fixed a minor little thing :)

user202729

So the cops have to golf the solution, too, and thus make submissions even harder to crack. (golf = unreadability)

AdmBorkBork

@StewieGriffin So, essentially you're posting golfed code and the robbers have to find ungolfed code?

user202729

No, robbers code must be shorter or equal.

caird coinheringaahing

@J.Salle o/

AdmBorkBork

Oh, I see, the golfed code is the hidden code.

Stewie Griffin

@AdmBorkBork Yes,,, or both can be golfed.. :)

@HyperNeutrino thanks :)

HyperNeutrino

np :)

AdmBorkBork

Right. So suppose I have a 6-byte Jelly answer and a LD of 2 to get a 5-byte answer. I post the 6-byte and say LD of 2, and the robbers have to find some code that's an LD of 2 from my 6-byte (no longer than the revealed code), which constitutes a crack.

But they could find a 6-byte that's an LD of 2 that solves it.

I like it. Definitely requires some creativity on the robbers' part.

Socratic Phoenix

@AdmBorkBork Agreed

Stewie Griffin

2:14 PM

@AdmBorkBork Yes, that's right :)

Anonymous

I like the idea. I think the cops have the tougher job

AdmBorkBork

Tougher job for the cops, more creativity required for the robbers. Should result in some interesting answers.

Stewie Griffin

@Mego, agree... Do you think it's too though?

Forcing LD==x instead of LD<=x makes it a bit harder (and might require a bit more creativity) for the robbers.

LD=0 would solve every cop post... It could be 1<=LD<=x though...

user202729

Sorry, misunderstood the messages.

Anonymous

@StewieGriffin Not at all.

Anonymous

@StewieGriffin Oh, I misread. I thought it was LD==x. I think LD==x is a much better version than LD<=x.

Though both would be good

Doing test cases for that challenge was a massive pain though.

AdmBorkBork

CMP: Do you solve your own challenges for the purposes of making test cases, or do you just roll the test cases by hand?

Personally, I extremely rarely solve my own challenges.

DJMcMayhem

@AdmBorkBork Sometimes, usually depending on how complicated it is

Pavel

@AdmBorkBork I generally do them by hand. In the case of BtB me and Wheat Wizard worked together on them for a good few hours, and then still ended up with suboptimal solutions for several of them.

Anonymous

@AdmBorkBork Same as DJ. I'll usually make my own test cases if it's easier than writing a solution to generate test cases. Frequently, though, I'll have a solution already that inspired the challenge. For example, my Largest Prime Exponents challenge came about from a piece of code I wrote for another challenge (that I incorrectly read).

C++ Question: If I have a simple struct, say struct foo {int a; double b; std::string c;}, then can I make a foo with foo bar(1, 2.0, "hello"), or do I need to explicitly define that constructor?

Poke

@Mego It's a common archetype. Consider folks in games like League of Legends and Overwatch. It's always their team who is bad and the reason they're losing. They're always diamond ELO.

user202729

@DJMcMayhem You can't.

But you can do {1, 2.0, "hello"} and then it should be converted to the desired type.

(C++11 uniform initialization)

@Poke Except me. I really am diamond ELO and just get stuck with crappy teams. ;-)

@DJMcMayhem Correct.

DJMcMayhem

@Poke I see the same thing a lot. It is pretty annoying to see

Pavel

@Poke I think that games can afford to suspend players for bad behaviour, esecially F2P ones. The fact that most people are assholes in a relatively unmoderated environment doesn't mean they are incapable of being polite in a more moderated one.

Anonymous

@Poke Yep, I have a friend who is like that sometimes. If it wasn't for his other qualities being redeeming, we probably wouldn't be friends. Also the fact that he is often right about the teammates being the problem helps.

@DJMcMayhem You can even do foo bar{1, 2.0, "hello"};

@Mego Oh, that's even better

@Poke that's why I like 1v1 games (I'm an MtG addict >.>). You lose, it's either your fault or your opponent's merit, no one else can be blamed.

Pavel

@DJMcMayhem Dota 2 allows you to report people for being a dick, and you can get communications suspended for 3 matches if you get reported by enough people in just a signle match.

DJMcMayhem

Although on the other hand, playing a round of Junkenstien's revenge where everyone immediately locks in the worst team comp imaginable (Torbjorn, Widowmaker, Genji), and I'm forced to go healer, before the widowmaker ends up leaving is pretty frustrating
