@Doorknob Also, newbie challenges that are tweaked a lot can easily get 10+ if fixed correctly

السلام عليكم

Doorknob

@Calvin'sHobbies true, but it's a start

How about "easy good questions" are questions with score >10 and votes < answers*3 or so.

Alex A.

@Calvin'sHobbies Yes, master.

The deed is done.

Doorknob

44.5% with score ≥ 10
34.0% [everything else]
21.5% closed/deleted with score < 0

3

that's in 2015

Alex A.

We have a lot of crap from the older days that wouldn't fly now but were fairly well received then.

Thomas Kwa

How does the proportion of questions with score≥10 compare with other SEs?

Doorknob

Couldn't say, since the deleted:all search operator only works on sites where you're a mod

Puzzling is ~25%

but honestly if you're comparing yourself to Puzzling you're already doing something wrong

Thomas Kwa

03:07

I wonder if the low questions-per-day influences people here to vote more.

Doorknob

not considering deleted questions:
PPCG: 60.3%
SO: 0.4%
CR: 6.6%

Thomas Kwa

wow

Calvin's Hobbies

@Doorknob That's 10+?

Doorknob

yep

percentage of questions with 20+ answers:
score ≥10: 14.4%
score ≤10: 1.4%

feersum

Wow. 84% unaccounted for.

quartata

03:15

It is puzzling that you would compare us to Puzzling.

Calvin's Hobbies

@Doorknob And how much of that 60.3% am I? ;D

quartata

oh snap

Doorknob

percentage of Calvin's questions scored ≥10: 90.3%

quartata

...nobody like my jokes..

Doorknob

only in 2015: 94.1%

percentage of Calvin challenges out of challenges scored ≥10 in 2015: 11.8%

Calvin's Hobbies

03:19

:D

@AlexA. Now post a cute animal that no one has probably heard of

Doorknob

number of Calvin challenges scored <0, including deleted, all time: 1

sorry, that's ≤0

Alex A.

El'endia Starman

My two questions have a total combined score of 20. Yay, 100% of my questions are >= 10!

(....statistically speaking.....)

Doorknob

not sure about that... :P

El'endia Starman

Well, on average at least!

feersum

03:29

100% of my questions in 2015 have score 18.

El'endia Starman

dang

Oh hey @feersum, did you understand my explanation of the numbers?

feersum

I think so

@El'endiaStarman One possible transformation for any sturdy rectangle is to swap a row/column with any row/column that's an even distance away from it.

Did anyone mention this earlier?

El'endia Starman

I don't think so.

@feersum Have you tested this yet?

feersum

I'm saying that it preserves the sums.

Should be easy to mathematically prove.

El'endia Starman

hmmm

feersum

03:38

For a program, this would be a lot more effiective criterion for weeding out duplicates than rotation/reflection.

Looks like you might be right.

Is this the song that was stuck in your head?

TheDoctor

@AlexA no, it's "forgot about Dre" buy Dr Dre

feersum

So for a grid of height H there are floor(H/2)! ceil(H/2)! permutations of rows, for example.

Alex A.

> buy

What is it with you and doctors?

TheDoctor

03:46

Lol Swype

El'endia Starman

@feersum I think I have an idea of why this works. It's both because A B C and C B A work and because even grids are toroidal.

feersum

No, it works for odd grids too.

El'endia Starman

@TheDoctor Skype?

El'endia Starman

That looks like it'll be super useful.

@AlexA. No.

You think doges can Skype?

Alex A.

@El'endiaStarman Yes.

TheDoctor

@AlexA why?

I meant Swype keyboard

Alex A.

@TheDoctor Skype keyboard?

TheDoctor

No

Look it up

El'endia Starman

03:52

@feersum Odd swaps can be done if you flip them end-over-end!

Alex A.

@TheDoctor No

feersum

@El'endiaStarman example?

El'endia Starman

 4 22  1 23  0

Holy cow, that'll be incredibly useful.

feersum

It's like you rotated just the 2x5 piece.

El'endia Starman

yeah

In this case, yes, but it'll work for any odd distance.

feersum

03:55

If we account for all the possible symmetries, there must be like 3 5x5 grids.

El'endia Starman

lol

I don't think it's quite that few.

TheDoctor

Good night golf team

El'endia Starman

Certainly though, it cuts it down a lot.

G'night Doctor!

said with a British accent

feersum

rotation, reflection, subtraction from mn, even row swap, odd row swap

for even sizes, cyclic rotation of rows

El'endia Starman

Reflection is covered by row swaps.

err

Hmm. Is it?

feersum

03:57

is it?

there's also diagonal reflection for squares

El'endia Starman

Diagonal reflection is definitely covered by horizontal and vertical reflection.

There are only 8 symmetries of a square.

feersum

ok

El'endia Starman

e, r, r^2, r^3, s, sr, sr^2, sr^3

feersum

what could be a minimal set of symmetry transformations from which the others are derived?

We need t find the group structure.

El'endia Starman

I've been pondering exactly that question myself.

I've been thinking of writing a program that finds cycles in sturdy squares. As in, you apply one transformation to get from A to B, and the same transformation goes from B to C, to ... to A.

This would highlight an element of the group because all elements will be equivalent to the identity if applied often enough in succession.

@feersum You can do this too for odd sizes; you just have to flip a row/column.

So cyclic rotation is a subset of row swaps.

feersum

04:03

But then the column was all upside down and whatnot.

Is that really the same?

El'endia Starman

22  1 23  0 24
17  8 16  9 15
12 11 13 10 14
 7 18  6 19  5
 2 21  3 20  4

Column cycling worked here.

Row cycling might fail, in fact.

Lemme try.

 2 21  3 20  4
22  1 23  0 24
17  8 16  9 15
12 11 13 10 14
 7 18  6 19  5

That was without a flip.

Sums still work out to 48!

No...

Not in the middle. Or the left.

feersum

I'm writing the program now ;)

El'endia Starman

FF finally fixed the permalink bug. \o/

Alex A.

\o/

Firefox? Don't you mean Iceweasel?

Mozilla Corporation software rebranded by the Debian project

In 2006, a branding issue developed when Mike Connor, representing the Mozilla Corporation, requested that the Debian Project comply with Mozilla standards for use of the Thunderbird trademark when redistributing the Thunderbird software. At issue were modifications not approved by the Mozilla Foundation, when the name for the software remained the same. The Debian Project subsequently rebranded the Mozilla Firefox program, and other software released by Mozilla, so that Debian could distribute modified software without being bound by the trademark requirements that the Mozilla Foundation had invoked...

Interesting read ^

Dennis

I don't use Debian, so no. :P

Haha, now my avatar is the Wikipedia logo.

@El'endiaStarman Yes, just now.

El'endia Starman

Interesting. Sounds like it might be affected by images you viewed last.

Yes.

I never would of thought how difficult it was to come up with spin-off names to JavaScript. The best I've thought of is KavaScript (K comes after J) which sounds horrible.

Dennis

From ECMA, I presume.

Alex A.

@El'endiaStarman It's a hard "g" sound. Not like the peanut butter brand.

Dennis

It isn't.

El'endia Starman

@AlexA. Its creators say it with a "j" sound.

Dennis

It's not "j" like in "Jeff."

@Doorknob We agree on important issues. Surely you pronounce "gif" with a g like in gravy.

@RetoKoradi Too bad I'm now famous for being predominantly incorrect.

Reto Koradi

Still better than people thinking you're always wrong. ;)

Alex A.

I did but the continuation of that with the beginning of the challenge didn't occur to me.

El'endia Starman

ah, lol

Reto Koradi

Well, unfortunately you're wrong about the pronunciation of "gif".

Alex A.

04:45

@RetoKoradi Don't do this to me, Reto. I thought we were like brothers. We spend every weekend together just hanging out. I confide in you.

Reto Koradi

Man, there's a whole web site about it: howtoreallypronouncegif.com

Alex A.

@RetoKoradi This is what I'm saying. I agree with this site. It's like "gift," not "Jif."

Dennis

OK, if you're citing blog posts, you've clearly run out of arguments.

Alex A.

Don't look at me, Reto's the one who posted it. It just happens to be correct.

Reto Koradi

I'm looking at the website author. Who is wrong. And cites blog posts in a futile attempt to convince us otherwise.

Alex A.

The website author is correct. The GIF author is wrong.

Steve Wilkasdfksd.

More like Steve Liar.

Reto Koradi

That web site says that the creator of the format insists on jif. But then claims that the people who write the Oxford dictionary know better.

Alex A.

They do.

alex-is-right ahhhhhh

Reto Koradi

So what are you going to do if they redefine how Alex is pronounced?

Dennis

It's a proper name. Creator's choice. alex-is-wrong

Alex A.

04:53

@RetoKoradi Who? My parents? I'd just go by my middle name.

Reto Koradi

No, the Oxford dictionary.

Alex A.

They don't define how to pronounce people's names, do they?

DLosc

Sure they do. They're words like any other words.

Alex A.

Hm. Okay.

Well then it's settled. If the pronunciation of "Alex" is revised by the Oxford English Dictionary, I'll go by my middle name.

I had seriously considered that anyway off and on throughout my life because I rather dislike the name "Alex."

what would people think of a new chat room to discuss golfing?

Alex A.

That's what this one is supposed to be for.

Actually it isn't. General discussion for codegolf.stackexchange...

xnor

yup

Alex A.

That's probably not such a bad idea, though I'm sure people will still discuss it in here as well.
