@DJMcMayhem Does Jelly qualify as non-trivial :p

caird coinheringaahing

@DJMcMayhem Can I use Python?

So something like while($n%2){$i++;$n/=2} would be ruled out?

@Mr.Xcoder Considering that it would take under thirty seconds to write it to, I'm gonna go with no

@WheatWizard I don't get how anyone can code in Brainflak, let alone golf it

Magic Octopus Urn

Dayum, the 2 first responses kick my groovy to the curb. It's never possible to win a prime anything with groovy ._.

7:42 PM

My algorithms class is "language agnostic" however they asked me not to do my labs in Brain-Flak.

25

caird coinheringaahing

@WheatWizard +1 to them, brainflak shouldn't be used outside of PPCG

100 bytes

Magic Octopus Urn

@WheatWizard you should do a commented brainflak answer, with indentation.

For my lab or the CMC. I'm working on comments for the CMC right nwo

Magic Octopus Urn

@WheatWizard also... my god I'm jealous about that langauge agnostic idea... we were forced to use university fabricated libraries and not even load the JRE when learning java...

7:46 PM

@MagicOctopusUrn :c I couldn't read that either :c

Magic Octopus Urn

@WheatWizard for your labs, I'm not going to try to understand it because Brain-Flak is one of those langauages where you need to know more than just the code... The context, the problem, etc...

I haven't upgraded myself to brain level yet xD

@MagicOctopusUrn One of my friends was actually able to get his TA to accept Brain-Flak answers. There is not a lot of code involved in the class.

Magic Octopus Urn

Brain-flak always is like (to me currently):
- Push some random group of integers.
- ?????
- HEY LOOK, DESIRED OUTPUT.

10

caird coinheringaahing

@MagicOctopusUrn For me, Brainflak is BRACKETS!!! Correct output

7:49 PM

That is definitely Brain-Flak in kolmogorov-complexity even for an expert

Magic Octopus Urn

I've read all the docs, managed to write hello world in 500x the bytes of the hellow world answer on ppcg... etc...

The "built-ins" are answers to other problems pre-golfed by smart people.

Brainflak is such math, you really don't even realize the crazy short solutions you can get until you really start thinknig mathematically ._.

Wasn't there a 10-20 byte modulous solution?

Here is my commented verison

> ((){[()](<{}>)}{})

Magic Octopus Urn

@WheatWizard is {({}(<(())>)){({}[()]<({}([{}]()))>)}{}} borrowed or yours :P?

@MagicOctopusUrn 46 is the record for stack clean modulus

7:52 PM

That is logical not ...

Magic Octopus Urn

LOL

@MagicOctopusUrn It is a bit of both, its modified from the parity code on the wiki

Magic Octopus Urn

@WheatWizard ooo... wiki? Is there a "rosetta-code" style site for brainflak?

github.com/DJMcMayhem/Brain-Flak/wiki

The wiki is just a repository of useful, short, stack-clean snippets.

How to check if a Pyth submission is decent: divide the python one's length by 4 and see if it is there. How to check if a brain-flak submission is decent: take the jelly one and multiply its byte count by about 100 (in most cases)

Magic Octopus Urn

7:55 PM

How to check if a Java answer is good: wait for 500 people to comment each upgrade to your small mistakes, if a week passed with 0 comments it's fine.

@brainflak why this:

Magic Octopus Urn

@Mr.Xcoder what is this math based on xD!?

@MagicOctopusUrn I have checked those on a couple of challenges, and those are the usual proportions (unless there are some crazy built-ins)

7:56 PM

@cairdcoinheringaahing The If part is based on the regular if construct but also performs a logical not at the same time. the else is just another if chained with the original

Anyway I've got to go. Bye o/

Its best if you understand how the logical not works in the first place.

caird coinheringaahing

Bye o/

@WheatWizard Wouldn't it be shorter to use debug flags in the code to print things?

The debug flags all produce extra output so they can't be used for stuff like that

plus that wouldn't be fun. If I wanted my programs to be short I wouldn't golf in Brain-Flak.

@MagicOctopusUrn no

I commented a brainflak program once

that's about it

Magic Octopus Urn

@Mr.Xcoder dude we should.

@Mr.Xcoder it'd be a fun project to get a universal golfing ratio between languages that auto-cached daily.

@Mr.Xcoder then we could work out a ratio-code-golf sort of thing with scaled answers.

@WheatWizard Have you told them all about brain-flak?

lol

Magic Octopus Urn

@DJMcMayhem I've known about the language for a long time; I've just... Not wanted to have to debug 10-60char built-ins.

@DJMcMayhem Is that different than Brain-Flak

Magic Octopus Urn

8:24 PM

@DJMcMayhem it's like linking 20 mathematical cars together with your brain and my brain hurts too much.

@MagicOctopusUrn If it helps at all, that's how I feel about every brain-flak program that I didn't write myself

ohey it's @El'endiaStarman

:O

It's significantly easier to write brain-flak than it is to read it.

Magic Octopus Urn

@DJMcMayhem To be fair I have subordinates who write Java code I struggle to comprehend: "why in god's name anyone would ever write anything like that" so I feel the pain...

Certainly reads like a write-only language

Magic Octopus Urn

8:25 PM

But brain-flak is more: "how in god's name" instead of "why".

El'endia Starman

[waves] Hi, I'm just dropping in to say that I've been working on TNBDE on and off over the last couple of months. There are several significant improvements, such as 1) recorded messages are updated when edited, star count goes up, etc, even in the distant past, 2) a lot more data (and more precise data), especially including markdown, and 3) responses to SQL queries are cached now (the cache is cleared when any part of the transcript is re-parsed).

13

that sounds great

@El'endiaStarman Good to see you in here again, even if it's just for a little while. :)

Magic Octopus Urn

Interesting, is this actively caching the chat?

Thanks for all the work you've done on TNBDE!

Magic Octopus Urn

8:29 PM

Or using the API :)?

El'endia Starman

I'm unaware of any official API for chat, in fact. I just scrape the transcript, basically.

Magic Octopus Urn

Nice, that's impressive :).

I, myself, haven't looked into any chat APIs for stack exchange.

If there isn't one, you may be able to release a library for $$$ ;).

@MagicOctopusUrn No pressure if you don't feel like it, but you should definitely try writing some simple brain-flak programs by hand. It'll make the language seen less intimidating. For example, getting the consecutive differences of the input is fairly simple

Magic Octopus Urn

@DJMcMayhem it's very simplistic, I agree... I just want a reason to do it :P.

@Riker Imagine snakes being wide instead of long :D

Magic Octopus Urn

8:32 PM

Have you guys seen this website: earth.nullschool.net

@MagicOctopusUrn CMC: consecutive differences between inputs. My favorite answer gets a cookie: (🍪)

Magic Octopus Urn

@DJMcMayhem ¥ >_>

Also, damnit I'll try.

I don't even know what language that is. You earn a carrot 🥕

@MagicOctopusUrn For the first version, you can assume all the inputs will be positive, and the differences non-zero

Magic Octopus Urn

@DJMcMayhem Added a link to the 1-byte solution lol

@DJMcMayhem 05AB1E even has friggin undelta... which has saved my buns in 2 challenges somehow.

El'endia Starman

@MagicOctopusUrn That's really neat. I've seen another one kinda like that, VentuSky: ventusky.com/?p=23.9;-65.3;4&l=wind I wonder if they use the same data source.

8:37 PM

@MagicOctopusUrn Hmm... -1 for a boring built-in, +1 cause osabie's a pretty cool language, and +1 for including a TIO link. You get an apple: 🍎

Magic Octopus Urn

@El'endiaStarman did you click "globe" at the bottom-left? It gives options including CO2 and monoxide emmissions.

@MagicOctopusUrn Is undelta just cumulative reduce by sum?

@MagicOctopusUrn Yeah, It would be fun

Magic Octopus Urn

@El'endiaStarman don't take it as the absolute truth and don't use it for scientific studies...

@DJMcMayhem [0, <YOUR ARRAY>] then undelta that.

@DJMcMayhem yes.

Magic Octopus Urn

8:39 PM

Also, I don't know if I have the 1/4 drunken ability to learn brain-flak at this bar ._.

El'endia Starman

@MagicOctopusUrn Oh, whaddya know, there's the source:

Gotta sleep now

O/

Magic Octopus Urn

@El'endiaStarman I'm also saying there's a massive lag at certain times that makes ocean current readings and wave readings not register anomolies. You can't see tsunamis on the wave animation. It's not great :(

@El'endiaStarman but, hey, it's close! I like it!

El'endia Starman

Very cool stuff, yeah.

Woah, you can drag around all the different projection types!

Magic Octopus Urn

I found the MPa settings most interesting.

8:42 PM

@DJMcMayhem 20 bytes My first Brain-Flak anything

Magic Octopus Urn

Seeing the air-flow at 10 MPa was like... wooooaaahh...

I wonder why in the upper-atmosphere there's such a circular pattern at the south pole but not the north pole.

@H.PWiz Nicely done! However, the differences are reversed

If you just reverse the stack before exiting/printing, it'll fix that

El'endia Starman

@MagicOctopusUrn Woah, cool! Looks like that's the jet stream around the north pole, and I'd conjecture it has to do with there being a lot of land around there.

Wait, no, looks like the jet stream is most apparent at 250 hPa.

Magic Octopus Urn

@El'endiaStarman I also looked up a couple famous whirlpool locations. If you click on a specific locale, it shows you the lon-lat. You can use that in combination with google maps and wikipedia to test how well it represents natural disasters. (Jesus those were BAD typos)

8:48 PM

I think you want {([{}]({})<>)<>}{}<>{}{({}<>)<>}<> instead

Indeed I did

I just saw that it had neither 0 or a negative number and posted

@flawr lawl

@H.PWiz If you're up for another challenge, can you make it work even if there are 0's in the input?

FTR, I have a 58 byte solution

@DJMcMayhem APL, 5 bytes: 2-⍨/⊢ (pair-wise reversed-subtraction across the argument)

@DJMcMayhem sure, what did you have without 0s?

8:54 PM

I think without supporting 0's, your solution is optimal

El'endia Starman

@MagicOctopusUrn: Another neat thing is that if you look at Hurricane Irma while stepping down through the layers of the atmosphere, you'll see that, generally, the lower layers are dragging behind the higher layers. Likely due to upper atmosphere winds pushing the hurricane along.

:D

I'm surprised. Also doesn't support consecutive equal elements

El'endia's back!

Oh yeah, I forgot to mention that also

My 58 byte solution does work with consecutive equals

8:56 PM

@Pavel What's up with his back?

El'endia Starman

@Pavel [waves] Hello. Dunno if I'll be ever-present like I was before, but I might drop in now and then.

@flawr /o_o

ATaco needs to make chat commands work on mobile

Magic Octopus Urn

@El'endiaStarman they did GREAT on wind-speed, I agree; however, ocean currents and such... BLEH... CO2 emissions, the scale seems misrepresented... I have a hard time saying "use this site for scientific approximation"

@El'endiaStarman Would it be ok to ping you in situations where we need an RO or would you rather not be bothered?

El'endia Starman

@Pavel At this point, I'd say it's probably best not to do so.

Magic Octopus Urn

8:59 PM

@El'endiaStarman also I couldn't constantly find the Norway whirlpools throughout the available dates.

Alright

El'endia Starman

@MagicOctopusUrn Hmm. What's the resolution of the data they have on ocean currents?

Magic Octopus Urn

@El'endiaStarman oh I have no idea, I found the site like ~5 hours ago.

@El'endiaStarman just thought I'd share :). Was trying to test it myself, but that's a good point on the resolution. I'm guessing it's looooow, in terms of the ocean anyway. Not sure the method of calculation though.

@El'endiaStarman I doubt it's based on ocean-sensors. I bet it's based on satellite patterns or something, making it register fake data (for oceans) (then again I could be super wrong, no idea).

El'endia Starman

@MagicOctopusUrn I know that NOAA has a network of ocean buoys, so that's probably a large part of it.

Magic Octopus Urn

@El'endiaStarman you don't put a bouy in a whirlpool/tsunami though, which may explain why my maelstorm search failed.

@El'endiaStarman that may be entirely accurate.

@El'endiaStarman I bet they take in a vector of power + angle and run with it using basic physics for the lack of data-points no idea though... I spent 5 paid hours today trying to figure out that website lol.

I JUST STOPPED MY SCRIPT THAT HAS BEEN RUNNING FOR ABOUT 2 DAYS

I AM SCREWED

Magic Octopus Urn

@2EZ4RTZ ... out of 2 days.

@2EZ4RTZ Can you stop yelling please?

Oi two days is a lot

Magic Octopus Urn

Agreed... but still, I've run brute forcers for 3 weeks before and lost the goddamn results due to power failure.

9:35 PM

@MagicOctopusUrn Yeah I needed 13k test cases for an answer and have 700 done

@DJMcMayhem sry

Happened to me, too (data analysis). Now I just resorted to streaming everything to BigQuery, because I'm incapable of keeping large result sets intact for more than a day.

Magic Octopus Urn

@2EZ4RTZ cant you start at index 700?

@MagicOctopusUrn Not really

@MagicOctopusUrn cumulative sum isn't pairwise.

Magic Octopus Urn

@Adám I'm, not in the correct frame of mind to write a challenge at the present moment lol.

Was just saying APL is amazing, but has a lot of SPECIFIC built-ins (though they're also versatile).

@Adám is there a golfing version of APL with a reduced code-page?

@Adám or is the whole language a code-page of 256 characters?

9:41 PM

@MagicOctopusUrn APL is not a golfing language, but almost all APLs have a SBCS.

Magic Octopus Urn

@Adám I just feel like APL has some commands that the TIO version isn't using because it'd make it an invalid language on PPCG.

@MagicOctopusUrn Actually, I think APL has less built-ins than most used languages, they are just well chosen :-)

@MagicOctopusUrn Huh, how can a language become invalid by having more commands?

Magic Octopus Urn

@Adám I've read your bios and wondered how much of a glacier the language is ;). "You see these commands, but there's always more beneath what you can see"

@Adám I thought our code-page limit was 255 single-byte characters before the 256th counts as 2-bytes?

@MagicOctopusUrn Well, APL has this powerful set of glyph primitives. I use most of them on TIO. The various implementations of APL each come with a large set of named "system functions". Most of them rarely find use on PPCG, and some straight out cannot be used on TIO.

Magic Octopus Urn

@Adám ahhh... so your commands are segregated by function? Like one implementation of APL uses matrix manipulation, while another may excel at base-conversion? Or am I way-off?

9:46 PM

@MagicOctopusUrn Right, Dyalog is the only APL which regularly gets new primitives (glyphs). However, we don't change the 256 char set (for backwards compatibility), so if we choose a glyph which isn't in the set, then it is only available as a glyph in the Unicode edition. The "Classic" edition instead gets a named system function.

Magic Octopus Urn

@Adám wow! I was actually right when I pulled information from my bum? Coolio, that's why I was so damn confused when trying to use APL. I gave up really fast though... Usually when I'm tryign to learn something I'm on break at work >_<

5:46 PM EST. I started my script to solve all of Microsoft Freecell

Magic Octopus Urn

@Adám I've seen some crazy mathematical solutions from APL (Dyalog) and wondered why some were qualified as "dyalog"

@MagicOctopusUrn No, the basic set of APL primitives, those that have symbols, are pretty much shared by all APLs (although Dyalog keeps adding more). It is mainly in the names addition system functions that there's emphasis on various things by various vendors, but even so, most things (like file I/O) is common to all.

Magic Octopus Urn

@2EZ4RTZ cries in binary again

9:48 PM

@MagicOctopusUrn codegolf.stackexchange.com/questions/43150/…

@MagicOctopusUrn That's too bad. I'll be happy to help you.

@MagicOctopusUrn One of the early ones takes 30k moves to solve

So far 16 solved

Magic Octopus Urn

@Adám the few things I've learned I've read from your answers :). The rest, I usually don't get a chance to compete in b/c either you beat me or they're not a starter-question :(

@MagicOctopusUrn E.g. Dyalog just added ⌺ (Stencil ), which is basically a generalized cellular automaton, and @ which amends items "at" specific positions in a very versatile way.

Magic Octopus Urn

@Adám Interesting, does each command come with a FSA diagram :)? I'd consume the shit out of those.

9:50 PM

@MagicOctopusUrn FSA?

Magic Octopus Urn

@Adám transition diagrams that explain state mutations.

@Adám though I got a C in that class...

@MagicOctopusUrn You mean a manual?

Magic Octopus Urn

@Adám I completely misunderstood cellular automaton, I'm an idiot.

@MagicOctopusUrn Think "Game of Life" built-in.

Magic Octopus Urn

@Adám I thought you meant you had "state transition diagrams" for all commands... Which is... horrifically wrong.

@Adám Jesus though, that's pretty cool.

@Adám are you guys planning to cover HMMs or anything that handles a system of probabilities in addition to that or? I need a new AI-focused language to learn...

9:55 PM

@MagicOctopusUrn So, e.g. the actual GoL, can now be written as C∊⍨⊢∘⊂⌺3 3 where C is a large constant (a 140 element list of 3×3 matrices).

Magic Octopus Urn

@Adám that's crazy... I forgot, APL has graphical output doesn't it?

@MagicOctopusUrn (Dyalog) APL is a complete applications' language. It has built-in support for all kinds of things, including WinForms, and now HTML rendering – not to forget the entire .NET…

Magic Octopus Urn

@Adám are you guys selling software to enterprises?
