Guys

How would I explain generator function or taylor series to the people here?

Bálint

Generator function: Can stop halfway trough

aditsu

@Bálint yes, my surname

El'endia Starman

@LeakyNun Where is "here"?

Leaky Nun

@El'endiaStarman in a challenge.

El'endia Starman

4:04 PM

And, since you said "Taylor series", I assume you mean "generator function" in the mathematical sense, right?

aditsu

also, we're descendants of the people from Dacia, but we mixed with the Romans and some other peoples too

Leaky Nun

@El'endiaStarman Yes.

El'endia Starman

What's the gist of the challenge?

Leaky Nun

@El'endiaStarman Generate the nth term of the GF or the taylor series

haven't decided on which yet

of tangent x

Bálint

@aditsu The people from Dacia are the people from Rome, Dacia was part of Rome

For about 2 hundred years

aditsu

4:06 PM

only after they conquered it

and I guess you're talking about the Roman Empire (Rome is just the capital city)

@quartata I want to make a new release, but I want to add a little more stuff first

Bálint

Yep, I do

quartata

@aditsu Wasn't saying it was a bad thing :P Just explaining why the "nightly" build is actually more stable

Luis Mendo

@aditsu So you're Romanian. I always thought your name (aditsu) sounded Japanese :-)

zʏᴀʙiɴ101

Be subscribed to chat until 19:30, when I release the zyabinVI new project ~~survey~~ poll ^_^

aditsu

@LuisMendo I also think it sounds a bit Japanese :)

but it also sounds Romanian

4:15 PM

@aditsu On second thought, maybe it's your avatar that looks Japanese :-)

@Bálint you probably know there's a significant Hungarian minority in Romania; my dad was part of it, so that's where the name comes from

Leaky Nun

@zʏᴀʙiɴ101 Nice.

4:19 PM

@HelkaHomba Vitsy is such a good name, isn't it?

Leaky Nun

@aditsu Is aditsu your real name?

Instead of something like adi<t>u where <t> is with hook?

aditsu

you mean adițu? that's not my actual name either, but yes, that's how I would write aditsu in Romanian

Leaky Nun

What's aditsu then?

Dennis

@LuisMendo No progress so far, unfortunately.

Leaky Nun

@Dennis Maybe you can help me.

aditsu

4:23 PM

a diminutive of Adi (which is short for Adrian)

How would I explain generator function or taylor series to the people here?

@aditsu I see, nice.

aditsu

kinda like Robert -> Bob -> Bobby

zʏᴀʙiɴ101

@aditsu I thought it was Robert ==> Rob ==> Robby.

Luis Mendo

@Dennis Anyway it's quite hot now. Better wait till September maybe

aditsu

that's also possible

but Bob is more common in my impression, and also it's not an exact prefix (just like Adi)

Q: Golf the Exponential Generating Function of tangent!

Almost every function can be expressed as a polynomial with infinite terms. For example, e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ... For example, sin(x) = x - x^3/3! + x^5/5! - x^7/7! + ... This is also called the Generating Function of that function. The coefficients of the n-th terms form ...

but pairs is better

quartata

hmmm

Cᴏɴᴏʀ O'Bʀɪᴇɴ

actually it can't be with an applied gerund, because J has no standard op precedence

I don't think they are wrapped

they implement an interface, but I don't think they get wrapped

the only reason i say it like that is because suppose you have a function invoke which is overloaded to accept a Runnable or a Callable

if you run invoke(() -> something()) which one is going to be called?

I have a question about git but I have no idea what to search so I'm going to ask here if anyone knows :3 :

So I have master branch:

    y-z

and I have develop branch:

    a-b-c-d-e-y-z

I want the structure to be:

  master:            y-z
  develop: a-b-c-d-e-y-z

where z-y are aligned, but git thinks it's:

  master:  y-z
  develop: a-b-c-d-e-y-z

any idea on how would I do the above?

Poke

but at this point implement vs wrapped is mostly semantics

xnor

in Haskell, is there a hack I can do to make foldl1 (,) [1..10] typecheck?

not for golfing, just playing with stuff

Poke

@Upgoat just for aesthetics?

zʏᴀʙiɴ101

@Upgoat You can also use the Stack Overflow git tag.

Upgoat

@Poke no, git thinks develop is like 225 commits ahead of master which isn't correct. This causes merge conflicts. Somehow "aligning" these would remove the merge conflicts everytime I made a fix

Poke

PS: I just recently discovered that (,) is a function. But now I am disappointed that (..) is not a function=)

@flawr yeah, enumFromTo isn't very golfy

@Upgoat if they're actually aligned is there a reason why you can't delete the local branch and pull it down again

Upgoat

@Poke what do you mean by that?

local branch = all the branches?

nevermind i understand now

you have additional commits on top of master

@flawr yes, and I'm not clear why it can't, since the elements of a tuple can have different types
