Thanks.

Now there's only 14 bytes difference between the version with the library and the version without the library.

@quartata The smallest digit string not appearing within the 10k decimal places is 1004.

@AlexA. I will do such things post-Bash

Idk man. It was there when I looked at it.

According to revision history, it was removed in revision 2 and snuck back in in revision 4 somehow.

It must have been my other answer that I removed it from the other time.

@SuperJedi224 Use lambda format:

x->{Long b=new Long(x[0]),d=new Long((x=x[1].split("/"))[1]);return b*d+new Long(x[0])+"/"+d;}

You have to specify that x is a String[].

(it doesn't say it has to be a full program. c:)

@SuperJedi224 Ah.

FlagAsSpam

@SuperJedi224 Lambda can be a function that returns a type - using the code I posted above and specifying that it accepts a String[] and returns type String is a valid form of Java answer.

You can apply the lambda conversion to the TFLP answer and I don't think you have to include the import declarations (going to look up citation for that now.)

Q: Using libraries in solutions

Languages differ greatly in the amount of functionality contained in the main namespace. Most of the PHP main functions, have counterparts in Perl core libraries. What should the policy be on character counts in such cases? For example, my solution for the NxN spiral used the Perl library Math::...

cat

@SuperJedi224 aha, thanks.

quartata

Replace floor() with the appropriate int cast depending on language

cat

@quartata mhm

quartata

In some languages floor gives you a float so beware

Alex A.

12:20 AM

@quartata Like Julia

Unless you explicitly say floor(Int, x)

FlagAsSpam

Why would floor give you a float?

SuperJedi224

@quartata In which case you can generally cast to an int

FlagAsSpam

That's literally the opposite of what you want to do.

quartata

@FlagAsSpam Because....

It is slower to cast it to an int afterwards

And you may be just fine with a float

cat

@FlagAsSpam I think some languages only use floats internally

quartata

12:22 AM

It gives you more choice

cat

FlagAsSpam

¯\_(ツ)_/¯ With autoboxing to float in operations anyways, it shouldn't matter.

cat

@FlagAsSpam I don't know what autoboxing is but I assume it's out of scope of my tiny, innocent, ancient language

quartata

@cat Casting from primitives to wrapper objects

It's a Java thing

FlagAsSpam

@quartata Not just that.

cat

12:23 AM

@quartata oh, i see

FlagAsSpam

Autoboxing also has to do with overloading of operators.

Alex A.

I have posted a lot of answers today.

SuperJedi224

I don't think an implicit cast from a primitive to another primitive is actually autoboxing

It's just an implicit cast

@SuperJedi224 Yeah - wrong terminology on my end. :D

Regarding meta.codegolf.stackexchange.com/a/7741/39328

What if we made answer upvotes only count for 5 rep each?

Alex A.

@ThomasKwa Why?

quartata

@ThomasKwa No

Thomas Kwa

That would be interesting. I don't know if that would be giving too little rep, though.

Alex A.

What's your reasoning?

Doorknob 冰

Thomas Kwa

I'm not saying it's a good idea

Alex A.

I don't think people should be given less incentive to post answers.

FlagAsSpam

12:30 AM

@ThomasKwa As le fencer said - no.

Thomas Kwa

@AlexA. Doesn't more incentive for questions = less incentive for answers?

Alex A.

Not necessarily

Doorknob 冰

no

Thomas Kwa

We're already one of the SE sites that give lots of rep, right?

El'endia Starman

I'm pretty sure questions/answers isn't really a zero-sum game.

Doorknob 冰

12:31 AM

@ThomasKwa You should try Arqade, if you think that :P

FlagAsSpam

@ThomasKwa Because we all up vote instead of just huffing and scrolling back up?

Thomas Kwa

Anyway, I'm in favor of questions going to +15, but I don't know if that would throw the rep balance off.

phase

Is free space in a ROM/binary file 00 or FF?

Thomas Kwa

That's why I brought it up.

Alex A.

What rep balance do you mean?

Thomas Kwa

12:32 AM

rep gained/effort spent

FlagAsSpam

Answers are hard too.

Thomas Kwa

which, as I understand, is already greater here than on other SE sites.

@phase 00

phase

@dog thanks

Alex A.

I think this is a good balance. It makes sense that good questions should be rewarded. I currently upvote almost 60% of challenges, and if upvotes give +15, I'll be able to be more selective with my votes, which would benefit the site. — Thomas Kwa 4 mins ago

Thomas Kwa

12:33 AM

Doesn't giving rep generously give us unfair attention that's drawn away from other SE sites?

Alex A.

Uh, why would selectively voting be better for the site?

You shouldn't be voting on things just for the sake of voting on them

isaacg

I just got the onion night hat - anyone know how one gets this?

Doorknob 冰

@ThomasKwa My philosophy is more like "take all the attention that we can get—we need it"

@isaacg nope, nobody's figured that one out yet

Thomas Kwa

Because I can just upvote the really good challenges, instead of "eh, this is sorta helpful; I think the author deserves +5"

FlagAsSpam

A lot of things here are upvoted a bunch because the work that we do is clever, not because we want to be noticed.

@isaacg Has something to do with hot network posts.

Any way to map new Date to [0,1)?

Doorknob 冰

The hypothesis is "lots of votes after n views," which is supposedly connected to HNQ because that's late votes

Alex A.

@ThomasKwa Upvote if you think something is deserving of an upvote, otherwise don't upvote. That should be the mindset regardless of how much reputation is awarded or taken away.

@Doorknob冰 He should've gotten it earlier, then, because he had ~10 up votes on a question with 7 views yesterday.

I think getting more rep for questions doesn't really help anyone. You don't get answers quicker, and people may not want to upvote if it gives a somewhat average question a lot of rep.

@AlexA. I don't think it should be raised at all. When I first found out about the difference between question rep and answer rep, I immediately found it a good idea. I think it depends on the site you're on, as SO questions usually don't require much work, while PPCG is the exact opposite.

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ What should 1 (or 0.999...) correspond to?

@cat I'm not talking about map in JS.

@El'endiaStarman ?

oh wait nevermind I know now

El'endia Starman

If you have an upper bound on the date, then divide new Date() by that upper bound and voila!

@phase You say that PPCG is the opposite of SO in that questions require work, but then why is that a reason not to award more reputation for that work?

FlagAsSpam

I have successfully found a meme for every variation of the word "wat".

phase

@AlexA. I was saying that as a counterargument to myself. 10 may be good to even it out across sites, it we can't make them per-site, but 15 is waaaaaay too high.

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ ...now I'm wondering what it is that you're doing where that would work.

12:43 AM

oh, lol

Alex A.

@phase I admit I'm not entirely on board with +15 but I haven't completely made up my mind yet. My proposal wasn't to increase reputation awarded for questions network-wide, it was for PPCG only. A developer confirmed that it can indeed be set on a per-site basis.

Doorknob 冰

12:44 AM

it was surprisingly easy

phase

@AlexA. I think a lot of the questions on PPCG aren't glorious puzzles that took 30 hours of work to research and create, a lot are like catalogs. Catalogs are a perfect argument against a rep raise, as they take a trivial problem (or just common knowledge) and make it into a "question" that will gets tons of votes. Other questions are great either. Look at everything not made by @Calvin'sHobbies. These questions don't deserve +15 or even +10 rep.

Doorknob 冰

@phase so don't upvote catalogs
