Was your number theory professor a satanist by any chance?

Hey @EᴀsᴛᴇʀʟʏIʀᴋ Wanna play some portal?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

can't

2 reasons:

wifi sucks

flawr

@quartata Not sure. But he did establish the ~~alphabet~~ abc conjecture.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:02 PM

and I'm supposed to be writing

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ oh, did you just start school?

ThreeFx

Portal 1 or 2?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2 is the only coop one

we both have completed each though

quartata

@flawr David Masser?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem no, next wednesday

ThreeFx

11:03 PM

Could be a speedrunning race or so

flawr

@quartata How did you know? XD

Eᴀsᴛᴇʀʟʏ Iʀᴋ

it's a long story, basically they are gifts

quartata

Well I know there was two guys and a google showed that he taught in Switzerland

Eᴀsᴛᴇʀʟʏ Iʀᴋ

lel

quartata

Anyways that's pretty cool

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:04 PM

@DJMcMayhem once I finish, i'll see how laggy I am.

DJMcMayhem

OK, maybe later than

flawr

He has a great sense of humour. =)

He also taught me to reduce fractions like 6 4/1 6 = 4/1 = 4

@flawr That's a projecteuler problem as well

Any current CMCs?

ThreeFx

What's a cmc

Could be a speedrunning race or so

quartata

@El'endiaStarman Completed tree is 121 megabytes

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem that's actually a pretty good idea.

Maybe portal 1?

quartata

11:08 PM

Will finish tweaking the bot in a few moments

ΛεγίωνΜάμμαλϠΨΠʹ

@quartata ?

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ ???

Speedrunning?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yes

DJMcMayhem

Racing each other? That could be fun!

ThreeFx

Do you know the routes?

DJMcMayhem

11:10 PM

No

I would probably just go straight through it

quartata

If you're going to race use SRL

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem yeah

@quartata okay

@DJMcMayhem same

quartata

Also, I think something might be off with the reply detection because this is how many replies this one message has:

Eᴀsᴛᴇʀʟʏ Iʀᴋ

42

quartata

Holy shit, it's too long

Gotta pastebin it

pastebin.com/b00rm9Up

Who knew ._. was such a popular message

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:12 PM

holy shit

TFW an unregisted user, from 1 answer, has 1.3k

quartata

As far as I can tell it's this message:

Feb 14 at 2:07, by Alex A.

._.

Which makes sense. Alex gets a lot of pings

Eᴀsᴛᴇʀʟʏ Iʀᴋ

lel

feersum

That's the replies to all the messages consisting of the text, "._." ?

quartata

No.

Oh, yeah

I totally forgot

quartata

11:15 PM

Messages that are identical get merged

No wonder. What an idiot I am.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

quartata

And yet something like That's interesting gets no matches

Eᴀsᴛᴇʀʟʏ Iʀᴋ

the '?

quartata

Don't think so.

That would only give it a score of one at any rate

Eᴀsᴛᴇʀʟʏ Iʀᴋ

also, that long wtf has no matches

feersum

11:16 PM

Needs more dots at the end.

quartata

Huh, no apostrophe did get a match

['Thats interesting!', ['I was hoping it would be good for golfing, but as it turns out, its terrible ATM.']]

Ohhhh

ThreeFx

Laziness

quartata

It's because of the HTML entities

ThreeFx

Or that. Yeah, let's go with that.

quartata

I'll reparse the transcript again then

this time I'll do html.unescape

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Nov 19 '15 at 2:56, by Doorknob

or to anyone but people who are new to the internet, really :P

that's in the list of ._. replies

it's not a reply

quartata

They aren't just based on replies

Eᴀsᴛᴇʀʟʏ Iʀᴋ

oh okay

@quartata what are they based on then?

quartata

A few heuristics

Lemme see what caused that one

DJMcMayhem

I'm about to post this:

A: Sandbox for Proposed Challenges

What base is this number in? code-golf math base-conversion Here's a seemingly trivial challenge that is more challenging than it first seems: Given a string that represents a number in an unknown base, determine the lowest possible base that number might be in. The string will only conta...

Do you think I should allow unary output?

feersum

If none of the other bases are bijective, why would you have bijective base 1?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:27 PM

@DJMcMayhem why is that hard?

it's the max index of the string [0-9a-z]?

feersum

Oh I thought you meant unary input.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

hey @Blue

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ Cause the turtle told me

6 hours ago, by trichoplax

It's definitely not as simple as it first appears

idk, I might edit that out

Blue

hello

ASCII-only

it's not trivial?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:29 PM

?

ASCII-only

i thought it was just map to value and get max

DJMcMayhem

Well, what would your solution be?

quartata

It has potential for nice tricks:

6 hours ago, by quartata

>x{x.chars.max.next} in Ruby then

DJMcMayhem

It would be pretty easy in some golfing languages, but I don't think it would be easy in python

trichoplax

@ASCII-only Me too, until I realised I was wrong...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:30 PM

@DJMcMayhem max index in the list

ASCII-only

@trichoplax how

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@trichoplax how doesn't that work?

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ Not sure how that would work

trichoplax

Off by 1

ThreeFx

max index?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:30 PM

then max index - 1?

ThreeFx

idk where you get index from tbh

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ The max index of 4815162342 is 2. The correct answer is 9

ThreeFx

^

ASCII-only

@trichoplax pre-offset by 1

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem I meant the largest digit/letter in the string, and it's position in a list

ThreeFx

11:32 PM

"a list?"

ASCII-only

a list = list of base digits, 0123456789 etc

DJMcMayhem

Exactly. The largest digit is 8, and it's position is 2.

Sorry, 1

Eᴀsᴛᴇʀʟʏ Iʀᴋ

no

DJMcMayhem

0 indexing and all that

ASCII-only

@DJMcMayhem no

ThreeFx

11:32 PM

you mean the list [0..9,'a'..'z']

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yes

ASCII-only

@ThreeFx also A..Z

DJMcMayhem

What's the shortest way of generating 0-9,a-z in python?

ThreeFx

> The string will only contain 0-9, a-z

Eᴀsᴛᴇʀʟʏ Iʀᴋ

list(map(chr,range(97,123)))

feersum

11:33 PM

Is output in base 36 allowed?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

^

then it becomes lambda x:max(x)

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ Not that simple

That's what my answer did

Luis Mendo

@DJMcMayhem Why do you say it's harder than it seems? Isn't it just determining the maximum digit and adding one?

quartata

You have to increment by one

ThreeFx

max + 1

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:34 PM

oh true

that's still not too hard though

DJMcMayhem

>>> list(map(chr,range(97,123)))
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
>>>

quartata

And that opens up a can of worms because of how ASCII is laid out

9 + 1 is :

trichoplax

This ^

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem yeah, i wasn't really replying to you

quartata

My answers works in (weird) bijective base 35: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, B, C, D, ...

abusing the fact that "9".next is 10 in Ruby for some reason and "A".next is B

ThreeFx

11:35 PM

Yeah, but that's fixed in 99% of all golfing languages by having a convert from a to 10 and so on

Eᴀsᴛᴇʀʟʏ Iʀᴋ

what's the output for the string "asd"?

ThreeFx

t

feersum

lambda x:['a',chr(ord(max(x))+1)][max(x)!='9']

ThreeFx

or whatever that is (20?)

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ 29

ThreeFx

11:36 PM

oh yeah, plus whatever before

ASCII-only

lambda x:int(max(x),36)+1 works i think?

ThreeFx

yep, should

feersum

Oh, that's better

DJMcMayhem

@ASCII-only That's a fantastic solution

feersum

lambda x:int(max(x),36)+1 I mean.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

11:38 PM

my deepest condolences to you

feersum

I was referring to your deleted message.

DJMcMayhem

Idk, should I post it?

ThreeFx

Yes. Does anyone second?

Downgoat

question: what sound does è make in french? idk IPA and all google answers give me IPA

DJMcMayhem

Would it be more interesting with base conversion banned?

Luis Mendo

11:42 PM

@Downgoat I know some IPA. What does the IPA say?

Downgoat

@LuisMendo /e/, /ɛ/, and /ə/

trichoplax

@DJMcMayhem Avoid banning things mostly

ASCII-only

@DJMcMayhem idk, it would certainly be longer

since you'll need to make the list yourself

Luis Mendo

@Downgoat /e/ is between English "bed" and "bid". /ɛ/ is "bed". /ə/ is the "a" in "sofa"

quartata

11:43 PM

@Downgoat Yeah, it's short e

Downgoat

@quartata so like "eh"?

quartata

Yeah, I think that's the closest.

Downgoat

@LuisMendo hm ok

Luis Mendo

@Downgoat Also, if you happen so speak Spanish, /e/ is Spanish "e". It's a little more closed than the English "e" in "bed"

Rohan Jhunjhunwala

@Downgoat do you think you can help me make a scoreboard for something?

Downgoat

11:46 PM

@LuisMendo all spanish I know: "hola", "no hablo espanol", "burrito", "taco", "salsa", "guacamole", "enchilada", "fajita"

what 2-letter name?
