Ah, I haven't sandboxed a challenge in a while. It's a nice feeling :)

Luis Mendo

@Angs Well, your suggestion was the key. I hope dividing by length is really a "fix" :-)

Rhombus Boxing code-golfgraphical-outputgeometry Given only a straightedge and compass, inscribe a rhombus inside the given rectangle, sharing two opposite points. Input Input is the dimensions of the rectangle. In the example shown, that would be 125, 50. You can take input in whatever way...

I've got code design problem: I need a better way for a game to indicate the types of players he wants. Right now, you can say "I need at least X players, and at most Y players, and I prefer Z players". However, for a game like Mafia, a game would need to be able to say "I need 3 of this type, another three of this type", or maybe even say "I need half the players to be X, the other half Y, and there can be anywhere between 2 to 20 players"

what would the interface for such a thing look like?

Geobits

Is this used to randomize players for individual games from a pool?

Nathan Merrill

yes

Geobits

3:23 PM

Hmm

Nathan Merrill

I'm currently thinking to let the game "pull" players, so if it has several types, it would call "getPlayers(int amount, PlayerType type)". The problem with this is that stuff like pairing up players by Elo doesn't really work that way

Zgarb

Maybe have a PlayerPicker interface with a method for picking a subset of players, and allow the user to make their own custom instances?

It's been a while since I've thought about OOP stuff.

Nathan Merrill

that already exists, to an extent. It's called a Tournament. A tournament is solely in charge of arranging the players into games, while I have another class for defining the game settings (like preferred player count)

trichoplax

If there are two types of player, will there be distinct submissions for each, or will each submission be capable of taking on either role?

Nathan Merrill

I hadn't considered the latter case

not sure

in my examples, they would be distinct, but I'm not sure if it really matters

I would simply need to add the player type to both sets

PhiNotPi

3:30 PM

For the problem you're trying to solve right now, each player only has a single possible role, and the game requires some number of players for a variety of roles?

Nathan Merrill

correct.

PhiNotPi

So the problem is how to rank the players? (One leaderboard for each role, or one overall leaderboard?)

Nathan Merrill

no, the problem is arranging the players

aka, which players go in which games

using Mafia as an example, the game would need to be able to say "I need 2 Mafias, 5 Villagers, and 1 Doctor"

and players would be able to define "I'm a Doctor"

however, maybe you want different Mafia setups each time

PhiNotPi

what's the issue with random sampling?

Geobits

I think your getPlayers(amount, type) would work fine. I see the concern about ranking, but...

Nathan Merrill

3:35 PM

or you want to allow huge Mafia groups, and make it percentage based

@PhiNotPi random sampling works fine, but its the interface of how a game defines what he wants

Geobits

For each type, give a setSize(totalPlayers) to override?

With a min and max to set.

Nathan Merrill

@Geobits how would this work with trying to pair up players with similar rankings?

PhiNotPi

you could... request a total number and then percentages, so "2 Mafias, 5 Villagers, and 1 Doctor" becomes [8,0.25,0.625,0.125]

Geobits

@NathanMerrill That seems like a separate concern, honestly. I don't know how you'd cram that in there.

Nathan Merrill

3:39 PM

@PhiNotPi that's not a bad idea

Geobits

You could weight players in your picker function based on elo/ranking?

So it wouldn't be impossible for a bad mismatch, but less likely.

PhiNotPi

although... it might be easier for you to do getPlayers(type,count) and let the game do all of the calculations, since the process for picking players could vary a lot between different KOTHs.

Geobits

^^ The problem there is outliers would play less.

Nathan Merrill

I like the percentages, but the biggest problem I see with that is that it isn't as flexible as the getPlayers(). the problem with getPlayers() is that many games require at least 2 players, but would prefer for there to be more in a single game, and so the game has to check how many players there are of each type, ect

bah, both have their advantages/disadvantages

trichoplax

Would you want to also specify a ranking, to guide which players are picked, or just to let the controller pick randomly at first and then pick subsequent players to match the first few chosen?

Nathan Merrill

3:44 PM

that's all dependent on the Tournament

currently the interface is List<PlayerType<T>> get(Scoreboard<PlayerType<T>> ranking)

trichoplax

So at this stage you just want a way of specifying number of players of each type?

Nathan Merrill

yeah

Geobits

@trichoplax In case you're wondering, it's all this game's fault.

trichoplax

I've closed the tab quickly before I get sucked in :P

Luis Mendo

@flawr In case you can take a look at the JS snippet:

Hard to say. The original spec (or the current one with unpaired surrogates) will probably be a disadvantage for languages that cannot handle it, so I'd stick to valid Unicode 9. Also, your scoring snippet does not handle characters outside the BMP as it should. — Dennis ♦ 9 mins ago

3:48 PM

Unicode 9?

Geobits

@trichoplax Haha, well it only took me a short while to get through the free levels. I'm debating whether to pay for the rest, but I probably won't.

Luis Mendo

^^ unicode.org/versions/Unicode9.0.0

Zacharee1

wow

that's a lot of chars

TuxCopter

Why is the addition of new emojis classed as important ಠ_ಠ

trichoplax

> 19 symbols for the new 4K TV standard

TuxCopter

3:50 PM

^ That also

trichoplax

I can't imagine 19 different things to say about 4K...

Zacharee1

@trichoplax you are joking right? :p

TuxCopter

We still wait for the advocad, the ( ͡° ͜ʖ ͡°) and the ಠ_ಠ emoji

Zacharee1

that Le Lenny looks weird...

trichoplax

@Zacharee1 I'm not - am I missing something obvious?

Zacharee1

3:51 PM

@trichoplax I think it means the symbols are refreshed to look good on 4k

but I could be wrong

Geobits

@TuxCopter There's an avocad in 9.0. That's why it's classed as important.

trichoplax

@Zacharee1 I thought the standard just defined them, rather than specifying exactly how they must be displayed. I'm not familiar though

TuxCopter

@Geobits :O:O:O:O::D:D:D:D:D:D

Zacharee1

@trichoplax idk

trichoplax

(You can still display a unicode character in different fonts)

TuxCopter

3:53 PM

@trichoplax There obviously are reference glyphs, but I don't think the glyphs are refreshed for the 4K standard

Zacharee1

@Geobits maybe it's important because it adds exactly 7,500 chars :p

@TuxCopter so then it must be 19 symbols having to do with 4k o_O

Geobits

No, it's definitely the avocado thing.

Gabriel Benamy

someone got my code ladder :(

trichoplax

@Zacharee1 I know there are 3 or 4 different resolutions referred to as "4K", but that still leaves 15 more symbols.

Zacharee1

ooh, 72 new emoji

I can do so little with that

TuxCopter

For some reason it display correctly in my terminal but not on FF. o_O

Luis Mendo

@flawr nvm, Dennis fixed it :-)

Nathan Merrill

why do we have avocado emoji, but no ninja emoji

I don't understand

Zacharee1

3:58 PM

found the symbols unicode.org/charts/PDF/Unicode-9.0/U90-1F100.pdf

@TuxCopter I just see squares in Chrome

Looks like they're not all for 4K exactly

look at the type of questions we get on AU askubuntu.com/questions/850513/…

TuxCopter

lol

“in ubuntu 15.10” and “since I installed ubuntu 16.10”

Zacharee1

yup..

or like askubuntu.com/questions/850505/…

"please look into this"? This isn't an office. We aren't employees -_-

TuxCopter

The worst thing is that the error report says nothing about the error

Zacharee1

uh huh

I think our most-used CV is Unclear

Geobits

My only regret is that I have no downvotes to give for your site.

@Zacharee1 I'm surprised that isn't crazy downvoted

Zacharee1

@DrMcMoylex we've given up ._.

sometimes things get downvoted but a lot gets ignored

Geobits

27 minutes and it's still open and only at -1? Given up indeed.

Zacharee1

we also have a more lenient downvote attitude

@Geobits we have 500+ people with 3k, but over 130 CVs in queue

Geobits

Sure, but it should at least be closed :P

TuxCopter

4:04 PM

@Geobits need to fix

DrMcMoylex

@Geobits Yeah, That was me, haha

Geobits

@Zacharee1 What's a queue? :P

Zacharee1

@Geobits the Close Vote review queue?

oh wait

Geobits

/joke

DrMcMoylex

The one that's always empty here?

Zacharee1

4:05 PM

@Geobits I realized that, after I said it

El'endia Starman

@Zacharee1 Sounds like you (and/or the mods) need a whip.

Zacharee1

@DrMcMoylex pls

Geobits

I did my time in the SO queues back in the day. I've seen things...

Zacharee1

@El'endiaStarman I do my CVs. Mods there don't want to close questions unless they're blatantly OT or Unclear.

El'endia Starman

@Zacharee1 I meant more for whipping the other users into action.

Zacharee1

4:06 PM

@El'endiaStarman I made a Meta post, got a lot of attention, CVs went down to 14, then idk what happened and they were back up to 96 the next day

El'endia Starman

On any given day, there are usually 10-20 questions in the CV queue on Christianity.SE, but I almost never touch it.

Zacharee1

10-20 ;_;

gtg I think

El'endia Starman

Yeah, granted, we hit a critical mass of users that want to help do stuff sometime last year and that's when my mod load dropped significantly. That's also about when I started participating on PPCG, actually. :P

DrMcMoylex

To put our review queues into perspective, I'm one of the most active reviewers and it took me several months to get the reviewer badge

Now I only have two

TuxCopter

:/ I upgraded my fonts but the advocad still don't show correctly

Oliver

4:11 PM

Anyone have feedback on this?

PhiNotPi

@El'endiaStarman You've ascended to the next stage of mod-hood, in which the amount of work you're expected to do cycles around back to zero, since you are no longer trying to "earn" your position or "prove your worth."

Sp3000

@Oliver Needs way more test cases, more constraints on input (e.g. matrix dimensions matching up) and notes on i/o formats (currently it reads as though only the weird multiline string format is allowed)

Also decide whether one dimension of the input matrix/matrices can be 0

Gabriel Benamy

Mathematica also has a builtin for it so it's kinda dull

Oliver

@Sp3000 Ok
