@MarsUltor oh cool

That's the extreme limit of a very skinny shape.

But the edge between the cases(e.g. [3,4,5]) has total angle 2pi

The method I have for the center outside is to solve for the largest angle equal to the sum of the other angles.

@feersum sorry, I think I had an implicit golf in here

@feersum I never multiply the total angle by 2

I should've said total_angle == pi

I actually ignored the /2.

@AlexA. huh wait, I think parts are compiled to machine code, something else runs that and dynamically recompiles when needed

@Downgoat @CᴏɴᴏʀO'Bʀɪᴇɴ ^

@AlexA. You just created this, didn't you? :P

@El'endiaStarman Yes

@QPaysTaxes Having just read the Wikipedia article on JIT compilation, I can say that's a (common) kind of JIT. Though it's really more like each newly-seen piece of code is compiled and then cached so it doesn't need to be compiled again.

Yeah, that's part of what HotSpot does IIRC.

I think JIT needs a room too...

→ 1 message moved to Chat Fortress 2

@feersum actually, I think I messed up

@feersum gotten excited by incidentally close numbers

@feersum At least it's marginally on-topic

Not really...what you'd want is native code there.

Oh interesting

@feersum Not always. In certain situations JIT is faster.

@MarsUltor Take this to JIT room plzx

@feersum there can never be more than one 'negative' segment, right?

I'm pretty sure JIT is on topic

^

@orlp I think so.

and it's always the largest segment

I'm totally fine with the JIT conversation in here.

@flawr The top two are amazing.

What we need is an asin2 that figures out the correct angle magically.

Off topic conversation is fine in here, it happens all the time.

Mostly for topics that will not be discussed long enough to merit a separate room

@flawr the comment I left on the other answer to orlp's question sort of applies to yours as well: if the link ever goes dead then referring to the paper as "this paper" gives people no way to figure out which paper you were talking about. even when you link to it, author, year and title should probably be part of the answer to ensure lasting value.

^ This. We should try to make this standard practice when referencing published materials on the site.

(The entire video is good, but I'm just linking to the last 3 minutes)

:)

you know, I've always been impressed by the amount of expert knowledge around here

for a site dedicated to fun and games, you guys are really smart

@AlexA. I was talking about math.SE, but sure. :) That said, off the top of my head I can't think of an answer that references specific published literature (although I'm sure we've got a bunch)

How is fastest-code?

like the state of the tag? It's one we often want to use, but rarely do

Is it a good idea if I want to post something there?

well, make sure its actually a problem that actually takes a significant amount of time.

@NathanMerrill well, not too surprising, it's programming fun and games

and make sure that you are ready to test all of the problems

@NathanMerrill ooh, I really like a lot of these :)

@Doorknob great :)

@NathanMerrill That would be more properly Arqade. :P We're more about problem-solving.

@NathanMerrill I don't need to.

I'm pretty sure its still about fun and games here

@KennyLau how do you plan on determining the winner?

@NathanMerrill Yes, but it's centered around problem-solving.

And who have you met that likes to solve problems for fun that isn't smart?

@NathanMerrill I can have them time themselves and then divide the time by a sample program I provide.

@MartinBüttner I know I've seen at least a couple but I can't recall where they are offhand

@KennyLau I'm not sure if we disallow that, but in times where that's been suggested, its been strongly discouraged

@NathanMerrill Well, I don't have every language downloaded

@KennyLau Not that hard to get all of them

@KennyLau right. We often require a freely available compiler

Alright.

for fastest-code

@NathanMerrill Is it alright if I just translate a problem to fastest-code?

@KennyLau assuming it would be a good fastest code in the first place, usually, yes

ok

If you are worried about the specs at all, I'd highly recommend the sandbox :)

@El'endiaStarman o/

@AlexA. I'm pretty sure I'd count you as smart.

Just because you're wrong doesn't mean you're not smart

That's very nice but honestly I'm like a tree stump compared to the rest of you awesome people.

@AlexA. Hey, at least you have the edge over us youngins :P

@feersum I solved it but it's not pretty

@AlexA. that makes me a block of cement

@quartata oh heck no gosh dangit

@feersum gist.githubusercontent.com/orlp/…

...guys, smartness isn't a linear scale...

@El'endiaStarman sshhh

O(no)

Very linear.

O(very)

O(wow such)

@El'endiaStarman says the guy with 5 smart

O(shit)

@orlp ...hwhat?

@El'endiaStarman well smartness is a linear scale, and you have 5

@orlp You write very nicely formatted code

@AlexA. It's Python. Of course it's nicely formatted. :P

Believe me, I've seen some ugly Python

@El'endiaStarman oh boii

give me one sec

...I was half joking!

I still think about that C++ garbage collection thing orlp posted in here a while back.

It looked so nice

I like to think my code is pretty

I don't know what I was thinking when I was formatting this

@Doorknob In my defense, it was around 4 AM and I had been awake for over 24 hours .-.

@Doorknob What

How does even what

@AlexA. ?

oh

how does it look nice?

@El'endiaStarman I present you

the worst Python code

I have ever seen

gist.github.com/orlp/1657509

The code looks so nice that it looks like it'll just work. Haha

[[trigger warning, bad code]]

> freaky_rect_switcharoo_2D

@orlp I could write better python :P

> add_wall_thing

> rock_and_ROLLY = math.pi / 8 * 180 #24

@orlp Yeah okay that's pretty bad.

Is there a story behind this code?

Lack of newlines for conceptual separation, long/repetitive variable names, and extremely inconsistent indentation...

I mean, surely nobody writes like this unless they're trolling... "mouse" is misspelled.

@AlexA. nope, I found it in the pygame example code

Oh okay

I probably have some worse code from when I first started coding

one thing can be learned from this

when in doubt about a variable name, just take a noun and add "y"

shit, I need a variable name for this unicode string

unicodey

@Doorknob Please go back and fix this it's bothering me so much

haha there are some gems in the cfractal source code that I don't even remember writing

^^

void v3(Point *p, float aff[6]) {
    float r = p->x*p->x + p->y*p->y,
          thingy = sin(r)*p->x,
          thingy2 = cos(r)*p->y;
    p->x = thingy - thingy2;
    p->y = thingy + thingy2;
}

@orlp That explains listy.

//NOTE: const power below (24) can be any even number
const int p = 30;

... that's not 24

hahaha

char buf[20];  // just to be safe. too tired to figure out the real value
sprintf(buf, "out%03d.ppm", num);

@Doorknob have you checked the rest of the file?

if there's a 24 anywhere in the file, it still counts as 'below'

that comment is the only place where the number 24 appears

:(

// NOTE: this one is also bad
void v20(Point *p, float aff[6]) {
    p->x = cos(M_PI * p->x) * cosh(p->y);
    p->y = -sin(M_PI * p->x) * sinh(p->y);
}

maybe the file gets concatenated with another by some preprocessor? :D

@Doorknob what is that supposed to mean

nope too large

        // do NOT try to "optimize" this by creating a 'rgb' local variable
        // for some reason that makes it slower

>_<

someone doesn't have his compiler set to optimize!

:P

:29066035 Tabs aside this isn't so bad

@AlexA. Why didn't that ping me? o-O

Because you deleted the message it was replying to

oh

@Doorknob Did you see the link I posted?

bc it was the answer to one of my unsolved puzzles on Puzzling >_>

hahaha

@AlexA. ok why did you star Phondue it doesn't even DO anything yet O_o

@Doorknob Why wouldn't I star it?

... :P

(not why doesn't it do anything yet)

Is there going to be a joke about having your cake and eating it too anywhere in Phondue?

(The answer should be "yes".)

hahaha

This was the beginning of a project that ended. I have no idea what it did >:|

function p(a,b){
	// a + 0 = a
	if(b==0) return 0;
	if(1) {}
}

Maybe Peano's axioms?

> // a + 0 = a

> if(1) {}

50% of te lines \o/

> }

Even the middle line is suspect, because I think the 0 at the end should've been a. :P

Looks like a half-assed truth machine

function p(a,b){ them variable names

Ok, that's every line now

XD It's probably Peano's axioms

Yup, found another file

function δ(x){
	return d(x);
}

function S(n){
	return n+1;
}

/*     multiplication     */
//           / a + 0 = a
// +:N*N->N: |
//           \ a + S(b) = s(a + b)

function p(a,b){
	// a + 0 = a
	if(b==0) return 0;
	if(1) {}
}

@Sp3000 If it's intended to be a truth machine then it's more like quarter-assed. :P

idk what function d was tho :(

Delta?

Yeah. The file was recursiveDelta.js, which is more descriptive than the actual code

Also, why the heck is multiplication denoted by +?

actually wait I have no idea

What did Peano do for addition?!

No, Peano was sane

I think all of you know

but just to be sure

whenever you do something with geometry

try doodling in geogebra

is there a way to detect an obtuse cyclic convex polygon given the side lengths without doing all the radius computation?

e.g. for n = 3 the check a^2 + b^2 < c^2 works

Obtuse meaning what?

do_you_accept_American_dollars do_you_accept_credit_cards do_you_believe_in_God do_you_come_here_often do_you_have_a_boyfriend do_you_have_a_menu_in_English do_you_have_any_pets do_you_have_children do_you_have_pets do_you_kiss_your_mother_with_that_mouth do_you_know do_you_know_who_I_am do_you_know_who_I_am?  do_you_mind do_you_need_help do_you_speak do_you_speak_English do_you_speak_something

I have no idea where this is from O_o

@El'endiaStarman that the circumcentre of the polygon lies outside the polygon

@Doorknob Terrifying o-o

@orlp Check to see if there's one side that's longer than pi times the sum of the other sides?

that's an 'obtuse' 4 sided cyclic polygon

My reasoning is that you're basically checking against a semi-circle approximation, in a way.

@El'endiaStarman I can't see that working

@El'endiaStarman I can make an 180-gon that's obtuse but very nearly fills the semi-circle

and a 3-gon that's not obtuse which is just straight lines

Wait, I had it in the opposite order. Check to see if one side times pi is longer than the sum of the others divided by 2?

@El'endiaStarman compare ACBE to ABF

ABF is not obtuse

Obviously you'd have to do some fiddling with it.

I presume you've already tried the a^2 + b^2 + c^2 ?< d^2 approach?

@El'endiaStarman doesn't work

Any chance you could tweak it by multiplying by a constant?

G'night!

with the git gui, how do you push the repo to github?

How can I now put my repo on github?

I normally use a different git app

First, create a repo on github

Then follow the instructions that appear

@AshwinGupta stop using the git gui and use the cmdline

Why do only some message show the little timestamp on the right?

To show that time has passed

But how does it decide which get stamped?

My guess is that it's every sixth message/every minute, whichever is smaller; fewer than 6 if a significantly longer amount of time passed.
