Using what lang/lib?

Jan Dvorak

It's a game that involves dragging cards with bits of assembler

ASCII-only

@Qwerp-Derp ok why not

betseg

@Qwerp-Derp what lang/lib?

Qwerp-Derp

@betseg Probs going to use PegJS for the interpreter itself, and I might just make a website

ASCII-only

@Qwerp-Derp 0/10 parser lib

Qwerp-Derp

07:11

@ASCII-only ;_; Can't be bothered with actual parser

ASCII-only

@Qwerp-Derp but it's a simple language just use your own parser like all esolangs instead of making a really large parser

Григорий Перельман

CMC: Given an int array `a` and an int `b`:
Output the first `b` numbers of the following series:
Numbers 1-len(a) of the series are just the elements of the array, e.g. `f(1)=a[1]`, `f(2)=a[2]`, etc. (This assumes 1-indexing)
Element `n` is the the sum of the last `len(a)` numbers in the sequence.
(This is a kind of extended Fibonacci thing)

Test case: [1,1,4], 7
Output: 1, 1, 4, 6, 11, 21, 38

Qwerp-Derp

Eeeeeh I want to mess around with PegJS

Matthew Roh

I have a challenge idea

A challenge where you dont get the amount and output the goats but reverse

Qwerp-Derp

@MatthewRoh ?????

Григорий Перельман

07:17

>_<

Matthew Roh

you input the goats, the output is the amount

I'll make up an occasion you forgot how many goats have you counted so far

Jan Dvorak

I'm wondering whom that offended

Qwerp-Derp

@ГригорийПерельман I would complain about not being able to type your username but I don't really mind because I can just do "@" and then enter and then boom

@JanDvorak ?????

Григорий Перельман

@MatthewRoh That is A) Silly and B) A duplicate

Matthew Roh

Why a duplicate?

Link?

(btw that was just an idea)

(the one I originally planned to write is a different one)

Григорий Перельман

07:19

It might take a while to find, but I guarantee there exists a challenge where you just count the number of instances of a certain string

Jan Dvorak

In retina it's just goat

Григорий Перельман

The last line outputs the amount of matches?

Matthew Roh

._.

Jan Dvorak

A regexp alone outputs the number of matches by default

ASCII-only

@ГригорийПерельман will b ever be less than len(a)

Григорий Перельман

07:21

Yes

It will always be at least 1 though

Jan Dvorak

two lines default to replace mode

Matthew Roh

Well the one I originally planned to is 'convert Bubblewrap to BrainF*ck'

Григорий Перельман

IDK what Bubblewrap is, but that seems more intresting

> Bubblewrap

I know what Bubblegum is

Matthew Roh

A BrainF*ck derivative where every character insists of O(non-popped cell) and X(popped cell)

Thats all for now

Jan Dvorak

well, that's much easier than from bubblegum

ASCII-only

07:30

@ГригорийПерельман JS, 92 bytes: f=(a,b,r=a.slice(0,b))=>b>r.length?f(a,b,r.push(r.slice(-a.length).reduce((x,y)‌=>x+y))&&r):r

JS, 91 bytes: f=(a,b,r=a.slice(0,b))=>b>r.length?f(a,b,r.concat(r.slice(-a.length).reduce((x,‌y)=>x+y))):r

I have a better idea

YES!

I'm a genius

XD

What do you guys think about my new profile pic

Jan Dvorak

nothing interesting about it

Matthew Roh

'nothing interesting' thats the whole concept

There's literally nothing

Jan Dvorak

well, there's a gray part and a white part

Matthew Roh

(Look at my profile page)

Wait

Should I Literally make it nothing?

Jan Dvorak

That's not possible. The best you can do is a transparent 1x1 image

betseg

08:02

You know the image that chrome shows when it cant load the image?

My pic was that at some point in time

Matthew Roh

@JanDvorak Yes, and that's just what I'm gonna do!

ASCII-only

@MatthewRoh remember transparecy only works for a gravatar

Matthew Roh

@ASCII-only Well then the previous approach is the best one probs

ASCII-only

@MatthewRoh previous approach?

Matthew Roh

@ASCII-only ^

literally capture the left side and stretch it at the size of a square

ASCII-only

08:05

@MatthewRoh can't you just use a gravatar though

Matthew Roh

Can we use a gravatar on SE?

Woah

I applied a better one

It's a corrupted one

:)

@ASCII-only How?

ASCII-only

@MatthewRoh you should just be able to select a gravatar from the avatar dropdown?

Matthew Roh

Gravatar isnt F*CKING sending a confirmation mail

I would like a resend, but they don't have that option

ASCII-only

08:23

@MatthewRoh D: what

@MatthewRoh so not in spam/deleted and it sent correctly?

Matthew Roh

I think so

Or maybe I registered ages ago and gmail deleted the spam

betseg

Is my avatar updated yet?

No it isn't

Matthew Roh

Wait, am I dumb

I could literally make a temp email account

or can I

Jan Dvorak

You keep using that word - literally - do you know what it means?

Matthew Roh

here is a potentially nice coding task. Compute the tag histogram of everyone on chat (separate for questions and answers)

not that I have any idea how to do it

ASCII-only

@felipa tag histogram?

felipa

@ASCII-only if you take everyone currently active in chat and look at the tags of all their answers, say (the tags of the question to which they have provided answers). You can make a histogram of these tags

ASCII-only

oh hmm

felipa

@ASCII-only does that make sense?

ASCII-only

does it have to be just everyone on chat

felipa

10:50

@ASCII-only well one idea would be compute over a week and see if there is a time of day bias

this might be more interesting for other *.se maybe.. I am not sure

@ASCII-only but yes it is supposed to be chat focussed. Some more interesting info about the kinds of people currently in chat

Guys, I have a programming question for you all.

I have a calculator app on my phone named Calculator++. I think I can program with it but I'm not sure

Anonymous

If it ends with ++, it's a programming tool :P

TuxCopter

@Sherlock9 This?

Sherlock9

I can define numerical functions with it, and there are functions for <, >, <=, >=, but I have no loop constructs that I can find.

TuxCopter

Can you recurse?

Sherlock9

Yes, that app, Tux

ASCII-only

12:07

idk but isn't ivy more like a language

Jan Dvorak

recursion is a form of looping

Sherlock9

@TuxCopter That's what I'm trying to find out

Jan Dvorak

Can it test primality and add two numbers? If so, you're good to go here.

Sherlock9

I think so, but I need a function to test recursion with before I try trial division primality testing

Fibonacci is what immediately comes to mind, but I wonder what else to try. Suggestions?

Anonymous

Just do addition by recursion

Anonymous

12:09

def add(a,b): return a if b == 0 else add(a+1,b-1)

Sherlock9

Oh hell. I don't think functions can call themselves

Hang on

Oh

OH

I just have to define the name (create, set, edit) and then it lists itself in the list of functions!

Ok the calculator is just freaking out now

Okay for add(x, y), a valid expression would x * eq(y, 0) + gt(y, 0) * add(x+1, y-1), right?

I think so

Matthew Roh

You know, you can hammer nails with screwdrivers (or can you?), but its very hard

changed to super strong fist

I mean super strong fist = less strong hammer

but super strong fist is more 'awesome-ish'

@JanDvorak No, it's just saying invalid expression near the gt part

Jan Dvorak

Not sure why

Sherlock9

I tried fib(x) with x*lt(x, 2)+ge(x, 2)*(fib(-2+x)+fib(-1+x)) and it doesn't have a validity error but the results are weird

Sherlock9

12:44

Alright, I'm starting to think that the answer is no here

I'm tempted to write a calculator app for Android

I've needed to learn Android anyway. The trouble is that I have neither the patience nor the temperance for updating and maintaining that app

Geobits

What app?

Sherlock9

We've been discussing this app, Calculator++: play.google.com/store/apps/…

I'm thinking of writing a similar calculator app that allows recursion somehow

Or a loop construct at least

Geobits

Is that the one you meant with "updating and maintaining"? Kinda confused now.

betseg

@Sherlock9 looks better than I thought it would

Sherlock9

@Geobits I said, I'm tempted to write my own app. I just don't want to update and maintain that app if I release it to the store

Does that explain things?

Geobits

Oh. Well maintaining something like that shouldn't be too bad. Updates are a different story, but you can do those as little or as often as you like.

I have a coding question... say I have a list of tuples like [(3, 0, 2), (0, 1, 1), (0, 3, 0), (1, 3, 2), (3, 0, 3), (1, 0, 0), (1, 3, 1), (1, 0, 1), (3, 2, 1), (1, 3, 0), (2, 0, 3), (0, 2, 1), (2, 2, 0), (1, 1, 1), (0, 3, 1), (3, 3, 3) ...

let's give two tuples x and y the same label if y <= x= < 2*x.

user165474

@Lembik Just any list of tuples, or specifically size-3 tuples? And I presume this is Python?

Lembik

how can I count how many distinct labels there are?

@HyperNeutrino they will be k-tuples for some k. It's k here as an example

user165474

So wait, x is the first value in the tuple and y is the second, right?

user165474

@Lembik Oh, okay.

Lembik

Example x = (3, 0, 2) and y = (0, 1, 1)

those won't get the same label

user165474

14:26

Oh okay. So how are tuples compared?

user165474

And I presume multiplication by a number is just scalar multiplication, right?

Lembik

yes scalar

you compare them by seeing if y <= x<= 2*x.

which in this case isn't true

user165474

No, like how do the inequality operators work on tuples? I think it compares each value and when two of them are unequal, it returns the result; otherwise, they are equal. But I'm not sure. This is Python right?

Lembik

oh elementwise

user165474

Oh okay.

Lembik

14:28

this is a python list but really I can translate an algorithm into python

user165474

So pretty much they have the same label if the second tuple is not larger than the first tuple, and the first tuple is not negative?

Lembik

no

(6,6,6) and (1,1,1) will never have the same label

user165474

Why not? (1,1,1) <= (6,6,6), and (6,6,6) < (12,12,12)

Lembik

argh! Typo by me sorry

user165474

Oh wait, did you mean 2*y?

Lembik

14:29

y <= x<= 2*y

yes!

user165474

oh lol

Lembik

(shame faced emoji)

Downgoat

@Riker yeah I had same idea. Maybe even showing contributing.md too

Lembik

@HyperNeutrino does it make sense now?

user165474

@Lembik Yes, it does. I'm working on a potential loophole I found.

user165474

14:36

And if it's not a loophole then this task becomes trivial.

Lembik

ah ok

user165474

(2,2,2) and (1,1,1) have the same label.

user165474

(4,4,4) and (2,2,2) have the same label

user165474

But (4,4,4) and (1,1,1) don't have the same label?

Lembik

right

(2,1,2) and (1,1,1) also have the same label

user165474

14:40

So wait, if (2,2,2) and (1,1,1) have the same label and (4,4,4) and (2,2,2) have the same label, then (4,4,4), (2,2,2) and (1,1,1) should all have the same label. But (4,4,4) and (1,1,1) don't have the same label...

Lembik

argh :)

user165474

yeah... :) it's not as simple as I originally thought.

Lembik

ok so I phrased it badly again.. we want to assign as many labels as possible according to the rule

so in your case we can give (1,1,1) one label and (4,4,4) another one

but (2,2,2) is going to get either of those two

let me think of a better way to make this formal

it's the maximum number of tuples which are not equivalent to any other

where equivalence is defined according to the y <= x<= 2*y rule

if it is clear at any point I would appreciate help with the wording!

How about..consider two such arrays of Hamming distances. Say x = (0, 2, 2, 3, 0) and y = (2, 1, 4, 4, 2) as examples. We say that x and y have are "close" if y <= x <= 2*y where the scalar multiplication and inequality are taken elementwise.

we want to count the number of tuples which not close to any others

is that better?

user165474

@Lembik Okay, so essentially we want to figure out how many tuples do not have the same label as any other tuples?

TuxCopter

Google.com displays correctly on IE 4 o_O

Lembik

14:48

@HyperNeutrino yes... although I screwed up the definition of label

user165474

Okay. So that makes more sense.

Lembik

@TuxCopter I am impressed you are running !

great!

AdmBorkBork

@TuxCopter That's not terribly surprising. Google has a pretty simplistic homepage because they want it to load fast, so I imagine that would work pretty well for backwards compatibility.

Lembik

what about lynx?

or dillo

AdmBorkBork

I would bet it loads just fine in Lynx

Probably loads just fine in Links, too

Lembik

14:51

dillo.org development seems to have slowed :(

Well, Google is pretty much the only webpage IE 4 can display

netscape?

AdmBorkBork

Mosaic, likely.

Lembik

ah yes.. netscape was too fancy :)

TuxCopter

@Lembik Win3.1 didn't even have a builtin browser

Win95 was the first Windows version to have a builtin internet browser IIRC

AdmBorkBork

Yes, that was IE

Lembik

Opera 3.62 runs on windows 3.1 apparently!

Riker

@Downgoat oh true, yeah

and I havne't used github enough but there's got to be a couple other good ones to include

maybe INSTALL.md/txt?

Jan Dvorak

genuine Win3.1, or emulated inside a browser?

AdmBorkBork

@TuxCopter Nope, apparently not built-in.

> It was installed as part of the Internet Jumpstart Kit in Microsoft Plus! for Windows 95 and Plus!.

Lembik

Internet Explorer 5.01, netscape 4 and opera 3.62 is the story

TuxCopter

@HyperNeutrino interesting!

TuxCopter

I might pose a challenge around this

AdmBorkBork

@TuxCopter I think there have only been one or two root changes in that time, so it's likely OK

TuxCopter

user165474

@Lembik Pretty straightforward solution, but yeah, I'd be interested to see a challenge about this!

AdmBorkBork

15:01

Root servers tend to be pretty static

Can you do an nslookup?

TuxCopter

Oh wait it does lookup correctly

No idea why IE says the page can't be accessed

AdmBorkBork

What's the page?

TuxCopter

Wikipedia

Lembik

@HyperNeutrino so the challenge, if I can write it, will be a little like codegolf.stackexchange.com/questions/54354/…

AdmBorkBork

That runs off of https, and the browser likely doesn't have the new TLS versions.

TuxCopter
