why was the python answer deleted?

Nathan Merrill

single quotes

instead of double

Dmitry Kudriavtsev

oh

Jonathan Allan

@xnor - you could do print{id+"'":1}

Sp3000

You can't concat a function to a string without stringifying the function first, and that's also just as long as xnor's existing :P

Jonathan Allan

@xnor - actually print{"'"*9:1} is shorter

xnor

02:06

there's print{"'":.1}

hmm, this seems version-dependent

it gives {"'": 0.10000000000000001} on replit but not in idle

Conor O'Brien

if it works in one version...

Geobits

...then it works in all versions?

...then deploy it to live?

Dmitry Kudriavtsev

i fixd mya nyswer

WHy do people always outgolf me?

even in python

ruby is supposed to be more concise?

wtf

DJMcMayhem

@NathanMerrill Think I should post a 0-byte V answer?

@DJMcMayhem you can, as long as you post the version. I won't technically be accepting an answer

Hmm print{"'":9e9} isn't any better

02:29

@Sp3000 Yeah. :/ There's no "natural" source for brackets or double quotes.

Sp3000

But yeah I feel like .1 is valid, just for the really old Python versions that don't round

xnor

@Sp3000 do you have an old version to test on?

Conor O'Brien

@Dennis holy cow that name tho

Sp3000

@xnor I should, gimme a few min first though

@xnor It might be more recent than we think - 2.5 gives a long decimal but 2.7 gives 0.1 (and based on Misc/NEWS I get the feeling the behaviour was still present in one of the alpha versions for 2.7)

@NathanMerrill CGP Grey

on the other hand, jukedeck (jukedeck.com) is an AI that generates music based on your specification. It does it free and the registration is fast.

noɥʇʎPʎzɐɹC

@ASCII-only JS is that funny thing that does what it claims to be and is the tacky but most practical language ever

Downgoat

@quartata yeah. It's really that JS is only language they know sufficiently because it's so simple

noɥʇʎPʎzɐɹC

03:57

JS is a scripting language, complete enough to separate itself from bash, but minimalistic enough to feel "scriptish"

A nonexistent stl, cross-platform like you've never seen, lots of quirks

Downgoat

JS itself basically defines a very primitively language. But nodejs promotes modularity with powerful module system

@ASCII-only ye, it is syntactic sugar

@ASCII-only c++ perf = C perf

@noɥʇʎPʎzɐɹC That's like saying PyPy is C with syntactic sugar

@Fatalize Wait, you actually believed that we'd get our design on November 1st? Well, do I have a great deal on a bridge for you!

@Emigna No just bad layout. They also forgot a key and crammed it in after the fact, together with the left shift:

ASCII-only

@mınxomaτ For some reason that is on my keyboard layout chart

mınxomaτ

That's a normal position, but it's not usually merged together with the shift key.

That was clearly meant to be just for the shift key (because the cutout is as long as right shift), but I guess they realized that a key was missing, so this happened.

@TonHospel no it's a lot! It went from 32 to 33

@TonHospel The running times are completely non-deterministic on my PC which I don't really understand

I mean n went from 32 to 33

@TonHospel I will give you my test harness

maybe it is broken somehow

I wonder if your gcc is bad at vectorizing. I didn't make the vector code terribly explicit to give other processors a chance too

Lembik

This is how I am testing it bpaste.net/show/af1b8fc87c58

@TonHospel it could well be.. I was reading locklessinc.com/articles/vectorize

seems gcc really need to be coaxed (although I am using 5.4.0)

hm.. the function name is wrong..should be Ryser

@TonHospel also bear in mind that I don't have 8 real cores. It is 4 modules and 8 integer processing units

Ton Hospel

Well, I did coax it quite a bit. If I look at the assembly it mostly generates what I want. I'd like to see the dissasembly though. Could you compile with -g instead of -s, do an objdump -S on the executable and paste that at a paste bin ?

ps, on my system runtimes are quite consistent

(not using your test harness)

g++ -Wall -O3 -march=native -fstrict-aliasing -fno-math-errno -funsafe-math-optimizations -ffinite-math-only -ffast-math -fno-signed-zeros -fno-trapping-math -std=c++11 -g TonHospel.cpp -lpthread -o TonHospel

MM, for my current version the float options should have no effect, but they don't hurt either

Lembik

@TonHospel paste.ubuntu.com/23378321

did that work?

Ton Hospel

Yes. And the basic vector code your gcc generates looks fine. Only the 64-bit and 128 bit multiplies are optimized a lot less than on my system.

I suspect that is the bottleneck or AMD is just bad at vectorized floating point arithmetic (I seem to remember having read such accusations)

No way to know without profiling

if you talk me through it I can profile the code

Does your system have perf support ?

Lembik

I have perf in any case so when you are ready I am too :)

Ton Hospel

It's a very interesting tool anyways. Read up on it. You can start by running the program with e.g. a 37x37 matrix as arg so it will run for a long time, the in another terminal run perf top and zoom in to the slow parts (make sure the program is compiled with -g, not -s)

i don't have pypy installed, but i mean, that line is run exactly once and not in a loop, so it takes trivial time and all

Lembik

@MitchSchwartz it's run many times as the function is called 36 choose 6 times

Mitch Schwartz

are you saying it causes pypy to fail altogether, or is there just some sort of warning

Lembik

no just not as fast as it might be

no warnings/errors

I am just trying to help pypy's jit compiler

@MitchSchwartz I have another fastest code challenge

Mitch Schwartz

you are using a test suite that includes 1947792 matrices?

Lembik

@MitchSchwartz yes.. the code is at bpaste.net/show/a48378f59263

Mitch Schwartz

is using indices better for pypy? row_comb = [sum(M[i][j] for i in range(n)) for j in range(n)]

and place the line defining n before that, ofc

do you think it matters, given that the line in the innermost loop will be executed 2^(n-1) * n more times than that line?

well for n = 6 it could matter, nvm

@DestructibleWatermelon Why doesn't this work? It should print "abc" but I can't get the turtle to move on past the "ab" no matter which direction I turn

Which direction does the turtle face initially?

@DJMcMayhem 0/10 using Turtlèd :P

Why someone downvoted this o_O

Rick roll?

@Lembik i know you're capable of figuring out what zip means, and how to implement it without zip

@TuxCopter :O woah

DJMcMayhem

@TuxCopter Because it's YouTube. Literally every YT video has downvotes

That's what I thought, but it doesn't work

@DJMcMayhem Never mind, <> are turns

Also yay Charcoal is getting a JS port so you will be able to run it as a Stack Snippet :D

Of course, I'll be the only one using it ;_;

@DJMcMayhem BTW Charcoal has a really bad really unfinished tutorial here

We're doing a canned food drive at work. The deadline is today at noon. Currently development has one can of spam, while support, test, and front office all have over a hundred cans. We're about ready to strike - we have hundreds of cans stashed in our desks and cars and everywhere.

Meanwhile our president said something to the dev manager asking why we are so disengaged from charity at work

Little does he know

GLASSIC

I'm fired because the program tester in our company forgot to compile the code before running it ...

Rainbolt

That's pretty depressing

I was feeling all giddy about our evil plan to out-charity the front office and now I am just sad for you, so I will get back to work.

How can a company possibly fire someone for this

Q: Sum Chain Sequence

Sequence: We start at 1. We first add the current 1-indexed value to the previous number in the sequence. Then we apply the following mathematical operations in order if they apply to this current value: Divisible by 2? => Addition Divisible by 3? => Subtraction Divisible by 4? => (Addition A...
