@Downgoat No I am a French penguin

quartata

Probably should take into account other attributes. For instance the two Direct Hits have different Strange Parts and the two Local Heros have different wears

flawr

un pingouin français

TuxCopter

@trichoplax I don't even know a golfing language that has tau as a built-in.

TuxCopter

Bonne nuit golfeurs

flawr

@TuxCopter Pareillement!

ATaco

BRB adding Tau to RProgN.

It doesn't even have pi

Downgoat

@TuxCopter so lime france?

Conor O'Brien

@quartata you have multiple strange direct hits

flawr

23:15

I think e and pi are overrated anyway, we could rewrite eulers equation as 0=ln(1)=i*tau... oooooOOh

Q: Draw nested radicals

Many formulas in math involve nested radicals (square root signs inside other square roots signs). Your task here is to draw these using ascii art. Specs You will be given two integers, the number inside the radical, and the number of radicals. I think the best way to explain what you have to d...

trichoplax

You mean e^(i*tau)=1?

Maltysen

@NewMainPosts wow that was fast

flawr

@trichoplax yep xD

Maltysen

@flawr that logic seems a mite shaky to me

flawr

23:20

since e^(i * tau) =1, then surely i*tau = ln(e^(i * tau)) = ln(1)?

Maltysen

._.

flawr

no?

Maltysen

ln isn't uniquly invertible over C

flawr

~~100~~ 99 points=) you mean e is not uniquely invertible. Because ln is.

trichoplax

I wonder if there's math-trolling over on Mathematics

flawr

23:24

Well let's stay in the reals

you surely know that log(x*y) = log(x)+log(y)?

Maltysen

yes...

flawr

But this also works for +, since e.g. log(1+2+3) = log(1)+log(2)+log(3)

Maltysen

hahaha

1+2+3 = 1*2*3

flawr

shhh

trichoplax

Perfect :P

quartata

23:26

@ConorO'Brien Two.

flawr

I've collected quite a few such pathological examples, and I think some day I'll release a book^^

Maltysen

@trichoplax maybe Puzzling would like it?

flawr

@trichoplax I'd love that=)

And if math.SE doesn't want it, we can still do it here in PPCG

trichoplax

@Maltysen That's a thought...

flawr

Oh and I have a whole collection abou 666

e.g. the euler phi function: phi(666) = 6*6*6

and 2^2+3^2+5^2+7^2+11^2+13^2+17^2 = 666

and 1^6 - 2^6+3^6 = 666

and 666 = sum(i from 1 to 6*6)

And 1000000000000066600000000000001 is prime

trichoplax

23:30

Did you find that prime on purpose?

ATaco

This is a good prime

trichoplax

This is prime

flawr

@trichoplax My number theory professor told me about it=)

It is Belphegor's prime

ATaco

It has 31 Digits, WHICH IS 13 BACKWARDS!!

Maltysen

@ATaco wikipedia?

ATaco

23:32

'Yeah

Xanderhall

Palindromic primes, anyone?

ATaco

That'd make an interesting challenge.

Find the n'th Palindromatic Prime.

flawr

what base?

ATaco

A002385

Base 10.

Not Unary don't do this to me

Maltysen

@ATaco pretty much done codegolf.stackexchange.com/questions/38240/…

trichoplax

23:34

We've had a few such challenges

ATaco

Darn

quartata

I cannot believe you have to use an external file for a web worker. Who designed this anyways?

Conor O'Brien

@quartata why tho? lol

quartata

"Wow, the unwashed masses really want threads. I know! Let's make the most watered-down gimped implementation of threads we can possibly think of"

@ConorO'Brien The constructor literally takes a path to a separate file.

Conor O'Brien

huhwat

quartata

23:36

Completely unusuable. Constructing the generator could take seconds. What the fuck.

ATaco

JavaScript is not ideal

quartata

The best part is all the SO answers trying to justify this design choice.

ATaco

I vote we replace Javascript with Lua.

VisualMelon

why not a good language?

quartata

We would have replaced JS with C++ a long time ago if that was even an option

ATaco

23:40

Name a good language that will work in a dynamic environment such as the web.

C++ is a terrible idea for the internet.

VisualMelon

well, C# is a good language, and it has that dynamic keyword...

quartata

Tell that to pNaCl

VoteToClose

:) I created some memory in redstone today.

VisualMelon

(my criteria for good language is mostly that it's statically typed, I hate the dynamic keyword)

quartata

That isn't the point though. The point is that allowing native code means any lanuage could be used with extra effort

ATaco

23:42

(Statically typed isn't very friendly on the web)

VisualMelon

why not?

ATaco

On the web, you're almost entirely working with text.

VisualMelon

so make it statically typed

if I have a string, I want to know I have a string

ATaco

type(a)=='string' too much effort?

VisualMelon

yes

ATaco

23:43

:\

VisualMelon

but that's beside the point

ATaco

Found the backend dev

VisualMelon

the computer won't tell me I'm wrong if I forget to add that

ATaco

That is a bonus.

VisualMelon

static typing is the best thing in programming ever and I can't understand why languages that don't support are used

ATaco

23:43

I do like working in a staticly typed environment, but I just can't see the benefit is worth it on the web.

VisualMelon

it has only benefits

if you don't want a statically typed language, then you are basically stating that you want to be able to write objectively wrong code

quartata

JS's type coercion is infuriating

ATaco

It adds a layer of Verbose-ness that the internet just wasn't designed to handle.

trichoplax

It would be nice if there were a statically typed web scripting language, and a dynamically typed one that is slower and uses the statically typed one in the background

VisualMelon

I disagree

the web was barely designed atall

quartata

23:45

It's 2016 we have type inference

ATaco

And Compiling is almost out of the question, Interpreting is practically required for HTTP.

quartata

literally no extra boilerplate

Maltysen

@VisualMelon you want to be able to do stringlike things with it. duck typing ftw

VisualMelon

@quartata it doesn't solve all the problems ;)

quartata

@ATaco That's a joke right? Peopleare already doing all sorts of crazy preprocessing to their JS

VisualMelon

23:46

I hate duck typing with a passion

VoteToClose

Here's what I did today. It's a single bit of tileable, flashable memory.

ATaco

Are you talking about minifying and such? because that is still technically interpreted.

quartata

@VisualMelon I've only ever had to specify a type in Haskell like twice. You have to do something pretty weird

ATaco

Static Typing makes me Overload a function 5 times when I only needed it once

VisualMelon

@quartata fair enough

quartata

23:47

@ATaco No I mean Babel, Webpack, etc. Ask @Downgoat about the glory of Grunt

trichoplax

It's fascinating how many different strongly divisive topics there are in programming

ATaco

Well, these are news to me. I hate frontend.

quartata

@ATaco As you should. It sucks.

VisualMelon

I agree

ATaco

I tried writing my Online Interpreter for RProgN using Front End JS. That was a mistake.

quartata

23:49

FWW I really don't care about static or dynamic typing. Just wanted to clear up any misconceptions. Static typing is a lot easier nowadays

Even C++ has auto

VisualMelon

that isn't dynamic

that's just type inference

(like C# var)

oh, I see what you mean

ignore me

quartata

:P

I didn't know about C#'s dynamic. How bad is the overhead?

VisualMelon

massive, breaks all type safety

not sure about performance though ;)

I think they made the DLR for stuff like IronRuby, and then just threw dynamic into C# for the hell of it

Destructible Watermelon

how to make a java?

quartata

Interesting

VisualMelon

23:53

I've never used it for anything, and never intend to

quartata

C# sounds like a bit more of an appealing target for transpiling now...

VisualMelon

... but why not just write the code in C# in the first place?

quartata

Too bad Mono sucks.

VisualMelon

mono is fine

I mean, it's Decimal is broken, and goto doesn't work properly

but those are edge cases

(which I have personally run into... but you know)

quartata

Still doesn't support C# 6, missing critical standard library pieces

DJMcMayhem

23:55

Technologically incompetent siblings are very entertaining.

> Brother: "xyz isn't working!" Me: "oh yeah, you just need some drivers." Brother: "drivers? Do we have any?"

2

quartata

oh dear

ATaco

Try technologically incompitent workmates

VisualMelon

The only feature I really use of C# 6 is readonly properties, it's mostly fluff that makes the language more complicated

Downgoat

@quartata eeewwwww grunt

VisualMelon

C# 4 is where things get iffy, because people actually use the TPL, and if you go much lower you run out of LINQ

Downgoat

23:57

gulps where it's at

quartata

@Downgoat I couldn't decide whether to say Grunt or Gulp so I flipped a coin

(for real)

Heads was Grunt Tails was Gulp

I don't really know anything about either so
