How'd you learn to golf so well, @Dennis?

Dennis

Practice. 1714 answers and counting.

(Some deleted, some not code golf. But anyway...)

Geobits

@TimmyD Maybe you're being choosier when picking challenges to compete in?

Dennis

I know choosier is a word, but eek.

TimmyD

@Geobits Decent thought. I haven't considered that.

Geobits

@Dennis Should I be choosier with my words?

Yodle

21:03

I think knowledge and creativity come into play a bit in golfing. Knowledge of the language you're using (your own language helps a lot since you made it), and using that knowledge in a creative way.

Dennis

twitches

Geobits

"more choosy" sounds worse to me :P

I could always choose my words more carefully, of course.

Shebang

Would picky be better?

Dennis

Choosy sounds bad, period. :P

Geobits

'pickier' works, but has a slightly negative connotation imo.

TimmyD

21:04

Choosy moms choose golf.

DrMcMoylex

More choosier?

Geobits

@TimmyD Only the choosiest moms.

@Downgoat I know right?

Geobits

Bandwagoners. I was the original down.*

>_>

Downgoat

i do not see a down in your username :/

suggestion: change name to DownDownGeobits

and make avatar red/black with -1

Geobits

There's not in muddyfish's either. It's all about the avatar :D

I will if you can get 25+ stars on that.

Geobits

Bring. Back. The. Skull!

muddyfish

@Geobits I do have a -1

It's just a bit small due to downscaling

Geobits

21:09

@muddyfish No, he said I don't have "down" in my username.

arda

If this message gets, idk, 5 stars, I'll change my picture to downpearl

Geobits

I need downstars for this. I don't want red all over the left side all the time :/

Oh wait, I can cancel stars. never mind then >_>

Downgoat

@Geobits cant u unpin since ur RO

Dennis

It's not pinned. I just eleven'd a star on my own message.

Geobits

Totally eleven'd

arda

21:15

oh boy it looks like I'll have to make a downpearl

Geobits

It's tempting to just remove them all, but I won't :P

Somebody ping me if it gets to 25, though.

Dennis

Don't worry, I will.

noɥʇʎPʎzɐɹC

@Dennis cancel all stars on first one, then post **25** Bring. Back. The. Skull!. Have one person star it, if more, cancel all stars and eleven another star. There, I sped it up.

Downgoat

@noɥʇʎPʎzɐɹC remind me to not make you RO on any rooms i own :P

Dennis

I already eleven'd one star. Doesn't work twice.

noɥʇʎPʎzɐɹC

Dennis

Can't. It has to be that one.

noɥʇʎPʎzɐɹC

arda

absolutely nothing = not breathing. Don't not do that.

Dennis

21:22

If I was going to eleven it, it would be to change the avatar. >_>

Downgoat

@arda i think he means absolutely nothing specific to the fact he achieved 10 stars

@Dennis ok, will create avatar and send too you

arda

@Downgoat yeah, thatsthejoke.jpg on my end

Downgoat

What does zip do

Dmitry Kudriavtsev

mkay

Shebang

If a = [1,2,3] and b = [4,5,6] are lists, zip(a,b) = [(1,4),(2,5),(3,6)] pairs up the elements

* is the splat operator, so for a matrix it will dump all of the rows

and then zipping makes them columns essentially

Posting from the phone is not a lot harder than by computer in 05AB1E since there are lots of chars I can't write on my keyboard either

Lembik

my question is.. people always make a fuss about specifiying randomness

how do I handle that?

@noɥʇʎPʎzɐɹC thanks

trichoplax

23:17

Do you want all possible matrices to have non-zero probability? Do you want the probabilities to have a specific distribution?

Is it OK to treat the standard PRNG of your language as uniform?

Helka Homba

Ooh. 467 hotness :) stackexchange.com/questions?tab=hot

Lembik

@trichoplax the distribution should be uniform over all orthogonal matrices

Geobits

Almost double the next hottest, which is also PPCG :D

Lembik

@trichoplax yes

trichoplax

@Lembik That's probably enough to specify it then

Lembik

23:20

@trichoplax ok cool thanks

trichoplax

So just generating matrices uniformly randomly and rejecting non-orthogonal ones would work, I guess?

Insisting on uniform distribution does mean that other approaches are less easy than otherwise

That's the advantage of just saying "non-zero probability for all" rather than specifying a distribution

Lembik

@trichoplax hmm... that is an infinitely bad idea :)

how are you going to create matrices uniformly at random with real valued entries?

en.wikipedia.org/wiki/Orthogonal_matrix#Randomization is a little unhelpful

trichoplax

@Lembik Since you have said we can assume the PRNG is uniform, we can use that assumption to imply that the generated matrices are uniformly distributed too

Lembik

@trichoplax the problem is that there is no uniform distribution on the real numbers

and 0% of the matrices will be orthogonal too :)

trichoplax

@Lembik Oh I see - even if we had a perfectly uniform PRNG, it's only uniform over a finite range

Lembik

23:25

right

trichoplax

So I guess it just needs either a range to be specified, or to say non-zero probability for all and the larger valued ones will just have to have very low probability (rather than insisting on uniform)

I think we've had infinite range random challenges before

Lembik

github.com/scipy/scipy/blob/v0.18.1/scipy/stats/… look for special_ortho

that's the scipy implementation

it's not so complicated

Q: Alternating fibonacci

In the alternating fibonacci sequence, you first start with 1 and 1 as usual. However, instead of always adding the last two values to get the next number, you alternate starting with adding, and every other time you subtract instead. The sequence starts like this: 1 1 2 # 1 + 1 -1 # 1 - ...
