I see that AoC has "λy.2018" as one of its ways to say this is the year 2018, anybody know what language that syntax is from? looks like apl or a derivative but I think that's :=

also I find it very amusing, I'm 90% certain the people at the top of the PPCG leaderboard (top 4 at least) are all non-US

considering each problem opens in the morning/mid afternoon for uk/turkey

Bubbler

@Riker I thought it's some kind of lambda calculus? I don't think it's related to APL

Also, the problems open at 2PM here in East Asia

Riker

@Bubbler see, you guys have a large advantage :p

it's 2100 for me, and i'm in the westernmost portion of the continental US (east coast has 0000)

@Bubbler ah yeah that's right, I was stuck on thinking about languages

though it's probably the syntax for some lambda calc esolang

Q: Summation through controu integration

I am trying to prove this sum formula. $$\sum_{n = -\infty}^{\infty} g(n) = \frac{1}{2i}\int\frac{\cos{\pi x}}{\sin{\pi x}}\; g(x) \;dx.$$ I do not understand why cos{\pi x} is needed here. This is because poles of sin{\pi x} are at x=0,\pm 1, \pm 2 .... Any help will be highly appreciated.

I have done a terrible thing. I wrote an Eval() command for my 2D language.

Pops a string, creates an execution context using that string as code, returns a Func<bool> that gets pushed to the pointer's stack, further executions of that pointer pop that func, invoke it (running 1 tick in the Eval-context), it returns whether or not it should continue executing. If so, push the func back onto the pointer's stack and don't move, otherwise increment pointer position.

@Cowsquack About a second for both parts, in Python. Didn't actually try in APL.

It'll be difficult to work with afterall, due to certain characters being unable to be read in string mode (namely " and \n) and any IP spawners inside the string will spawn a pointers in the base code as well (so that's 6 characters that are problematic).

Considering the 5+ seconds F# needs to print Hello World, isn't it a weird choice for scripts?

Pavel

Not if I'm working on advent of code and will only run the script once

user202729

It's just a more convenient way to compile& run them from the console.

However usually it doesn't work when there is >1 optional arg.

AdmBorkBork

16:37

I like how it used 101% of the CPU to process that.

Pavel

Probably some parallelism in the fsharp interpreter

Dennis

It used 1.01 cores on average. Calling that 101% is a weird choice.

Nathan Merrill

I feel like that is normal. I remember at an old job where we had 1600% cpu

Skidsdev

for some reason I have the sudden urge to learn C and make an interpreter for a CIL-inspired language

@NathanMerrill at my old job we used AWS virtual instances, and it was always fun to see a 4 core VPS reporting a load average of 879 in htop

Pavel

@Skidsdev Why learn C? The C# interpreter is written in C# and the F# interpreter is written in F#.

Skidsdev

16:48

@Pavel right, but their job is to transpile said languages to CIL afaik, not execute said CIL

DJMcMayhem

@Pavel Why not learn C?

Skidsdev

also ^

Pavel

That's a good point

Skidsdev

that point is much more valid than mine, because .NET Core, which does execute said CLI, is still 60% C#

Pavel

@Skidsdev So what you actually want to make is an runtime/assembler?

Skidsdev

16:51

@Pavel interpreter in the sense that it parses and executes the code in realtime, like JavaScript. ie: as opposed to a compiler

CIL-inspired ie: has similar syntax to CIL

Pavel

Ah

Nathan Merrill

Well, my favorite language for language parsing is Scala.

it has a fantastic library called fastparse, and everything else in scala is awesome too :)

so I recommend Scala, even though you probably won't take it :)

Skidsdev

I won't

Pavel

From what I can tell, Scala is to Kotlin what Luigi is to Mario

Skidsdev

@Pavel better, yet underappreciated?

J. Sallé

16:54

@Pavel better in every single aspect?

Pavel

Basically, yeah

Skidsdev

does that make clojure wario?

Nathan Merrill

The only complaint I have about Scala is how much people love to use custom operators so it can be really tough to figure out what a piece of code is really doing

Dennis

I don't know, I always felt like Luigi was a little green.

Pavel

If you think of "Non-shite JVM language" you think of Scala, Kotlin, Clojure, and Groovy, which I've been trying to cram into my mario bros. analogy but haven't succeeded at yet.

Skidsdev

16:57

@Pavel which one's the best JVM Language?

Pavel

Ironically, Java

Zacharý

That.

Pavel

Also, libc

Which is extremely difficult to use compared to many other languages' standard libraries

Zacharý

When you see a segfault in not C / C++, you know you screwed up.

Skidsdev

@Pavel it seems to have piss poor documentation

I think all stdlibs should take a leaf out of Mozilla's book when it comes to documentation to be honest

because, as questionable as JS might be, MDN is by far the best and easiest to use docs site I've ever used

even better than MSDN, which is also really good for C#

DJMcMayhem

@Zacharý Even in C/C++ you know you screwed up when you see a segfault

Pavel

I was about equally prepared for the answer to be C, Perl, or Cheddar

quartata

@Pavel the trouble with perl is that you have to use real camel probiotics for that and theyre too expensive

anyways: why sodegarami

you see the only time you die at te hands of a katana is if your rich. the samurai would not waste katanas on commoners

but the sodegarami were the instruments of direct oppression against the lower classes. theyre infused with there screams.

and it just makes the experience much richer

@PostLeftGarfHunter thank

J. Sallé

@quartata you should probably read something about Tsujigiri if you really believe that

Skidsdev

@quartata depends which edition we're talking about

in 5e the katana is 1d8 Versatile(1d10)

meaning you can 2h it for the 1d10, then switch to 1h (free action) to grapple

because according to the RAW you need only 1 free hand to grapple

however in 3.5e, the last edition to include the Katana as an official weapon, it was just a 1h 1d10 weapon

@Pavel So open just returns you a raw filehandle whereas fopen gives you a nice userland file object that takes care of buffering

AdmBorkBork

You just need to keep your finger on the previous page so you can go back if you don't like your choice.

quartata

All of the f* operations are just hiding the syscalls from you but it's good because doing raw read is painful

Pavel

19:50

fscanf is nice, yes

quartata

even fread. the idea is that it reads as much as can be efficiently gotten in one syscall and returns bits and pieces of what it got on demand

that's that buffering

splintering it across many reads is inefficient

especially if youre working with lines

userland does some important things (citation needed)

Pavel

I'm confused by fread

It has arguments for number of items and size of item

Doesn't it just read in a single continues stream of characters?

quartata

you can make each block bigger than one character

i guess for faster moves from the buffer

Dennis

It's just to make your code clearer.

quartata

size*count

Pavel

20:03

@Dennis Oh so like what calloc is for

Post Left Garf Hunter

Idea: Instead of Haskell's Prelude having functions in terms of concrete types you have each function related to a type class (e.g. instead of and :: Bool -> Bool -> Bool you have and :: (Andable a, Andable b) => a -> b -> Bool).

Pavel

I have a macro, #define TALLOC(type, count) (type*)(calloc(sizeof(type), count))

Dennis

@Pavel What would you use instead of calloc?

Pavel

@Dennis malloc and multiplication

Dennis

calloc returns zeroed memory.

So you can always use calloc instead of malloc (although it might be slower), but not vice versa.

Pavel

20:09

TIL, I thought both were zeroed

Dennis

Memory blocks returned by malloc might be zeroed. Large memory blocks use mmap (which returns zeroed memory), unless a freed memory block can be recycled.

Would that usage of parentheses be considered standard usage? (n=1)∧(b=0) instead of (n=1)∧b=0? Or are both equally good-style code?

dzaima

21:21

also 1 0 ≡ n b is a possibility

Adám

@Zacharý It is quite normal when trying to clarify a structure to the reader. E.g. one might define parallel resistors as R←{÷(÷⍺)+(÷⍵)}.

@dzaima Yes, but that is then more removed from TMN, and the symmetry breaks at the partial inequality.

@dzaima One could also move the "otherwise" up:

 H←{ n(a b)←⍵
     n=0:b+1
     b≠0:H(n-1)(a,H(n)(a,b-1))
     n=1:a
     n=2:0

 }

@Zacharý You should rather ask about H(n)(a,b-1). That's decidedly un-APL'y.

Pavel

F#, some amount of bytes: let rec f x y=function|1->x+y|n->List.replicate y x|>List.reduce(hyperoperation(n-1))

Adám

@cairdcoinheringaahing It is really quite simple. It is a higher-order function. ⍺⍺ is n and ⍺ is a and ⍵ is b.

Pavel

Which ungolfs to:

let rec f x y =
    function
    | 1 -> x + y
    | n -> List.replicate y x |> List.reduce (hyperoperation (n-1))

Which has less useful currying behaviour than

let rec hyperoperation n x y =
    match n with
    | 1 -> x + y
    | _ -> List.replicate y x |> List.reduce (hyperoperation (n-1))

Adám
