@Sp3000 it was for calvin's challenge, so that doesn't work :(

Yay, we're up to 8 questions per day!

:D

@Mego Not necessarily a good thing

Quality is more important.

anOKsquirrel

11:03 PM

most are good quality

@Mego does your headcanon include Cajova_Houba=Calvin's Hobbies?

@ThomasKwa Like @anOKsquirrel, most are good quality. Plus, the bad ones don't survive long enough to really make us look bad. We're quick on the closehammers.

Doorknob

11:05 PM

@Mego still not up to 10, which is what SE claims a "healthy" (graduated) site should have (which is nonsense)

Calvin's Hobbies

18 of our last 50 questions are closed/negative/duplicates

I guess dupes don't necessarily count as bad quality though

El'endia Starman

What we really need is a SEDE query that looks at questions over the last week/month and compares (number of questions with > +5 score)/(number of questions in total).

TanMath

Hey all!

anOKsquirrel

yeah

El'endia Starman

That'd probably be a better indicator of the average quality.

hi TM

hiiiiiiiiiiiiiiiiiiii

@Doorknob Yeah, it should be scoring quality over quantity

quartata

base=2;
while (mod(sqrt(length(dec2base(x,base))),1) > eps)
  base++;
endwhile

All right, first step down.

anOKsquirrel

ewwww, this is the smallest transpose I could find: :D,mQ2m*{W%2b}%{D=}%

quartata

Octave's built-in dec2base only works up to base 36 however...

@ev3commander You have open cv Python?

@Calvin'sHobbies Sorta, yeah.

unless it's like mathematica or something

@anOKsquirrel yeah

@Tanmath no..

TanMath

@anOKsquirrel I did not even notice this...hi!

@anOKsquirrel for what? Pyth?

anOKsquirrel

@TanMath what?

@TanMath no cjam

@ev3commander oh, that is sad

You mean like this? -> cjam.aditsu.net

yes

@ev3commander I know, so?

@ev3commander so?

@anOKsquirrel no it isn't! I do not like stack based languages!

@TanMath You don't like them because you don't understand them, which is a poor reason for disliking them

@TanMath you did, when you made ShortPy

@TanMath You have. Many times.

@Mego can I implement a combination feature in Seriously? Plus, you still haven't made a Lucas number feature

@Mego ok, so can I help implement it?

@TanMath You could fork it and make your own version

@Mego I planned to hound you about this mercilessly

@TanMath If you wish. If it doesn't work, I'm not pulling/merging it, though.

@Calvin'sHobbies I would, but then I would be making my own language derived from Seriously

@TanMath not if you make a PR

Calvin's Hobbies

@TanMath So?

TanMath

@Mego but what would its command be?

@TanMath Which? Lucas numbers or nCr?

TanMath

@Calvin'sHobbies ok, what should I call it, TanMath's Seriously ?

@Mego for now I will go for nCr

anOKsquirrel

@TanMath you could just fork it

TanMath

11:24 PM

@anOKsquirrel I know..so?

Calvin's Hobbies

@TanMath I don't care

anOKsquirrel

@TanMath gives up

Anonymous

@TanMath Pick a character that is open and has an adjacent open character, because nCr and nPr should be next to each other

TanMath

Ok... And I put it in the fn table as a lambda?

Or as a full function, whichever works better

who has an implementation for Calvin's thingy?

the sequence with bases and stuff

Calvin's Hobbies

What now?

TanMath

@anOKsquirrel what do you mean?

anOKsquirrel

whoops, not you calvin

The Lucas number command will be a two-byte command, because I don't see it being used often enough to justify it being a one-byte

Martin's sequence

sorry

El'endia Starman

Martin himself, obviously. :P

anOKsquirrel

yeah, but...

I made a cjam program for it and i dunno if it works

TanMath

@Mego how can you have a two byte command?

El'endia Starman

By the way, it's worth noting that you don't really have to do any base conversion for it, I think. Just look for when log_b(n) is a square number.

anOKsquirrel

it was convert to base, transpose, convert back, right?

Alex A.

11:30 PM

@Mego :O Is your professor a UW alumnus?

TanMath

@anOKsquirrel really? When was this?

El'endia Starman

Well, you'd still have to do the process, but you wouldn't have to do any fiddling with characters.

Given N, find the lowest base b where N has a square number of digits. Arrange those digits in a square matrix, transpose it, and convert back from that same base.

@El'endiaStarman cool! Will he post it as a real challenge?

it works!

@Mego so nCr has two invites, how do I get those two inputs? I have to use the pop function two times?

yes

I think I will stick to lambda

Q: Reverse and square

In this challenge you will compute numbers from a curious sequence. Your input is a single decimal nonnegative integer. Reverse the bits in this integer and then square the number to get the required output. When reversing the bits you must not use any leading zeroes in the input. For example: ...

Let n be the input. While n is divisible by 2, n = n / 2. Output n**2.
