@Quill How many keys do you have left? =)

I don't know my typing speed so I can't calc it myself :(

@PeterPeter I believe that's not allowed. Once there was a bot here, quite a while ago, but the owner was asked to move it to another room.

Quill

@zʏᴀʙiɴ101 There's a website that can calculate your typing speed

ProgramFOX

Actually the same thing happened when I ran my own bot in here.

zʏᴀʙiɴ101

@Quill Well, I'd better go typing the chat transcript with a special offline program timing me. >_>

sentenc.es

Katenkyo

I tend to write pretty fast as long as I don't have to think about what I'm currently typing

zʏᴀʙiɴ101

12:08 PM

^^ actually a system of four websites representing four personal policies that limit your email responses to: two.sentenc.es, three.sentenc.es, four.sentenc.es, five.sentenc.es respectively.

Who here uses these?

avocad juic

0/10 they don't handle more than five

zʏᴀʙiɴ101

Just take a pre-determined amount, name it to your receiver(s), and tack on the sentenc.es signature to your messages. :P

flawr

@Quill An infinite number of keystrokes would be way scarier.

zʏᴀʙiɴ101

@Quill How many keys do you have left? =)

Quill

12:33 PM

Let's assume.

At my age, a very fast typist with 60 WPM has ~266112000 keys left.

That's 532 programs to golf >_<

For 30 WPM that's halved to ~133056000 keys.

266 programs >_<

@Quill So, they suggest blogging every email. Some emails don't deserve to be blogged. >_>

@Quill 52 words per minute :)

-1 not realistic: at least 50% of all characters typed are chat messages

zʏᴀʙiɴ101

@NathanMerrill Not really. I wrote 10317 chat messages here.

What is the single line message maximum length in chat? :/

avocad juic

@zʏᴀʙiɴ101 500 characters per line

zʏᴀʙiɴ101

Thanks.

@NathanMerrill 10317 messages is 5158500 keystrokes maximum!

Nathan Merrill

lets say you use 1/10th that

Nathan Merrill

no, you're going to use 38% of all of your keystrokes chatting

zʏᴀʙiɴ101

@NathanMerrill Yes.

:O

Nathan Merrill

assuming that 1. you use appx 50 keystrokes per message, 2. that the estimator was correct, and 3. that you will continue using chat like you have in the past 6 months

That's a large waste of keystrokes.

@Quill let me calculate the amount of keystrokes you chat away...

@Quill you have posted 7270 messages here until now, right?

Quill

yeah, in here

zʏᴀʙiɴ101

The maximum length of a single line message is 500 chars.

Let's assume you use 1/10th of that.

Therefore, we can expect you to type 1274472 keystrokes per year.

Now, how much years you had left? >_>

According to your SE network profile, 73.

@zʏᴀʙiɴ101 means my breakfast was very tasty

@trichoplax but they were one of the earlier sites though

zʏᴀʙiɴ101

But I meant the language Cheddar, not breakfast cheddar >_>

trichoplax

@Upgoat Are later designs more restricted? I just hadn't realised there was that much potential for variation from the basic theme

The image on the front page is the "image of the week" as voted for on meta. Seems a really nice idea. Doesn't translate directly for our site, but it made me wonder if there was some different thing that we could do here

@NathanMerrill could work, they key is lazy evaluation

El'endia Starman

....I guess I should go write that parallelized sieve of Sundaram blog post real quick...

avocad juic

2:59 PM

@Upgoat 0/10 No ping

Nathan Merrill

so, if you're on the number 50, you'd have a queue, where 2->52, 3->51,...

avocad juic

@El'endiaStarman You haven't already?

El'endia Starman

@avocadjuic I've said multiple times that I should or that I want to, but I've just never gotten around to it.

Upgoat

@flawr may or may not be me

Nathan Merrill

and you peek the top of the queue, and see if the number maches the next number

the problem is that that requires O(N) memory

zʏᴀʙiɴ101

3:01 PM

@Upgoat is Cheddar finished? >_>

Nathan Merrill

er, the sieve already requires that

huh, a generator for the sieve is actually really cool

Jester Tran

What is a generator?

Nathan Merrill

they allow for infinite lists

so, in python:

Upgoat

100/10

Nathan Merrill

def range():
    x = 0
    while True:
         yield x
         x = x+1

@JesterTran when the function is first called, it goes then stops at the "yield" function. Then, on next iteration, it resumes at the yield, and continues

avocad juic

@NathanMerrill Basically xrange

Lembik

I mean in a purely functional style

avocad juic

@Upgoat TIL juic can program, also &df?

Nathan Merrill

@Lembik does the concept of functional make sense?

Bálint

@Lembik That's nice

The problem with Haskell is that it's a language built on lazy evaluation and nobody's actually called for it.

Lembik

@NathanMerrill I think so

@Bálint :)

Nathan Merrill

3:12 PM

or is it a specific technique that Haskell is using

Lembik

@NathanMerrill it refers to mutability I think

Nathan Merrill

@Lembik to an extent. If you have a non-functional language, you can still make a function functional, as long as you don't mutate the variables passed to you (or any globals)

Lembik

@NathanMerrill Right if you are willing to suffer you can do anything :) I mean Haskell is implemented in C and then run in machine code :)

Nathan Merrill

def map(list):
    new_list = []
    for i in list:
        new_list.append(i+2)
    return new_list

Upgoat

@avocadjuic &df is supposed to become disapproval face but Gboard is messing me up:|

Nathan Merrill

3:15 PM

for example, the above function is functional, even though new_list.append() is not functional

quartata

@Upgoat Why?

Lembik

@NathanMerrill I think the key word was "pure" above :)

I mean that was an important part of "purely functional"

Nathan Merrill

yeah

Upgoat

@quartata either Hilary or trump in office isn't exactly desirable

quartata

Reality check. Having Bernie as president would be great, but his viewpoint is extreme (and a little unrealistic). History has shown that in the fight between a democratic extremist vs a republican, the republican wins. (Granted this will probably change in a decade but still)

I hate to say it but I would be much more concerned about the odds of Trump winning if Bernie was nominee.

Fatalize

3:17 PM

"his viewpoint is extreme" wat

quartata

@Fatalize For America

Fatalize

oh right

Nathan Merrill

extreme == radical changes

Fatalize

not that extreme though

Zgarb

@Lembik Something like this may be the simplest solution.

quartata

3:17 PM

Yeah I know from a worldwide perspective it looks pretty tame but we're operating in a 1950s mindset basically

Lembik

@quartata hmm... I am not sure I understand. Are you worried about what Bernie would do if elected or worried that he won't be elected?

Fatalize

He could advocate for strict gun control

Lembik

@Zgarb oh thanks!!

quartata

@Lembik Neither. I'm saying he probably wouldn't win if he was nominee

Nathan Merrill

its not about how extreme the viewpoint is, but how many changes it would cause in america

Lembik

3:18 PM

@quartata that was my latter point

quartata

Oh, OK. My bad

Lembik

I prefer extreme left as they always get moderated

TimmyD

@quartata Really? Because practically every poll shows that Bernie has a better chance of defeating Trump than HRC does.

Upgoat

@Fatalize upset hillbillies? :/

Lembik

extreme right sometimes actually implements it

quartata

3:18 PM

@TimmyD Lemme put it like this:

Bernie would attract the hardcore blue states but Hilary would also attract those since let's face it they would rather have anyone but Trump

Lembik

@TimmyD Her Royal Clintonness?

TimmyD

@Lembik Hillary Rodham Clinton

quartata

Bernie would not win in the swing states because he's too left but Hilary would do significantly better because she's more of a centralist

Lembik

@TimmyD I know! Humor clearly not working :)

quartata

The only thing Bernie would get over Hilary is the youth vote, which is (sorry) unreliable and relatively small

Lembik

3:20 PM

@quartata in a year where a near fascist reality TV host has been chosen as the primary winner, predictions seem tricky :)

quartata

Also I hate to say this but California isn't as liberal as we look; I don't think Bernie would do too well here (as the primary showed). I suspect there would be something similar in New York

TimmyD

May 5 at 20:40, by TimmyD

The US is so far right-leaning as a whole that Hillary Clinton is considered a left candidate.

3:26 PM

@Zgarb it would be great if one could ask pure functional programming challenges

what languages other than haskell exist to answer those sorts of challenges?

flawr

For that I'd like to write a "function" that partitions a list in to two sublists (one greater or equal pivot element, one smaller)

But I have trouble on how to go about that.

Fatalize

"function" triggered

flawr

What do you call it then

Fatalize

what have you done yet?

@flawr Predicates

flawr

partition(_,[],_,_).

Fatalize

@flawr you call recursively your predicate with [H|L] as second argument

Zgarb

3:29 PM

@Lembik You can write purely functional code in many languages (like Python), but I think most languages that require it are Haskell or ML derivatives.

Fatalize

but your end condition is the empty list

Lembik

@Zgarb is there an objective way to judge if python code is purely functional?

Fatalize

[H|L] is one element bigger than L

so you just get an infinite loop cause the second argument gets infinitely large

Lembik

I am trying to work out if one can make a challenge that doesn't exclude all other languages

Fatalize

@flawr partition(_,[],[],[]).
partition(P, [H|T], [H|A], B) :- partition(P, T, A, B), H =< P.
partition(P, [H|T], A, [H|B]) :- partition(P, T, A, B), P < H.

Your end condition was wrong, if L is the empty list then A and B are also empty, not anything

and you got the H part wrong in the 2 other rules

You want to recursively check the first element of L, so you have [H|T] in the head of the predicate

then you call recursively on the tail T

flawr

3:33 PM

@Fatalize ah now i see, i was not really thinking recursively

@Fatalize Thank you very much!

Fatalize

@flawr you're welcome :)

flawr

Still taking my very first steps=)

Fatalize

they are the hardest, once you "get it" it becomes much easier

flawr

@Fatalize After the second line, I could add a cut, right?

Fatalize

also you should probably put the H <= P and P < H at the beginning of the rules

so that the recursive call is last for tail-recursion

@flawr Generally you don't want to add cuts ! if it's not needed

Zgarb

3:37 PM

@Lembik I guess so, if one uses the (somewhat obscure) Wikipedia definition. If you ban all side effects and variable re-assignment, and require that objects are immutable, I think you should always end up with purely functional code.

flawr

Doesn't the interpreter optimze that?

@Fatalize Oh ok.

Zgarb

But it may be difficult to adapt to all languages.

flawr

@Zgarb Functional BrainFuck

Nathan Merrill

@Lembik this drastically depends on the granularity you want

Fatalize

@flawr As an example of why you don't want to add a cut such as partition(P, [H|T], [H|A], B) :- !, partition(P, T, A, B), H =< P.

Nathan Merrill

3:38 PM

I can make a single statement functional

Fatalize

?- partition(3,Z,[1,2,3],[4,5]).
Z = [1, 2, 3, 4, 5] ;
Z = [1, 2, 4, 3, 5] ;
Z = [1, 2, 4, 5, 3] ;
Z = [1, 4, 2, 3, 5] ;
Z = [1, 4, 2, 5, 3] ;
Z = [1, 4, 5, 2, 3] ;
Z = [4, 1, 2, 3, 5] ;
Z = [4, 1, 2, 5, 3] ;
Z = [4, 1, 5, 2, 3] ;
Z = [4, 5, 1, 2, 3] ;
false.

without a cut

Nathan Merrill

or a function functional

avocad juic

@Zgarb Many languages are multi-paradigm though

Nathan Merrill

or a program functional

Fatalize

but with you only get
partition(3,Z,[1,2,3],[4,5]).
Z = [1, 2, 3, 4, 5] ;
false.

which is less general :p

Zgarb

3:39 PM

@avocadjuic Yes, but the goal seems to be to ban the non-functional parts.

flawr

Oh now I see, thank you very much for the example!!!

avocad juic

@Zgarb ban?

Nathan Merrill

making a program functional is easy: simply don't read/write a file, a window, network, or console

Zgarb

10 mins ago, by Lembik

@Zgarb is there an objective way to judge if python code is purely functional?

Fatalize

@flawr This also shows that your predicate is well-made, because it works in multiple directions with only a single implementation :p

Nathan Merrill

3:41 PM

making a function functional is also simple: never modify parameters, or variables outside the scope of the function

(as well as the side effects listed with a program)

avocad juic

@Zgarb Hmm, that would probably need IDE-level variable recognition (?)

flawr

@Fatalize I appreciate your help, can I give you a tip in form of a virtual piece of chocolate?

Fatalize

@flawr if you used CLPFD for the inequalities, you could even get the following behavior:
partition(_,[1,2,3,4],A,B).
A = [1, 2, 3, 4],
B = [] ;
A = [1, 2, 3],
B = [4] ;
A = [1, 2],
B = [3, 4] ;
A = [1],
B = [2, 3, 4] ;
A = [],
B = [1, 2, 3, 4].

or this:
partition(I,Z,[1,2,3],[4,5]).
I = 3,
Z = [1, 2, 3, 4, 5]

What is CLPFD?

Pretty cool predicate all around :p
