Hey guys, do we have toroidal languages here?
My friend is asking why we execute instructions in a line rather than, say, a ring, and I thought we might have some toroidal 1D or 2D languages here.
 
fairly sure we do
><>, for one
befunge as well
most 2d languages do, except for cubix
toroids are the rule, not the exception
 
I'm having trouble coming with 2D languages off the top of my head
 
? you mean remembering ones that exist? or thinking of new ideas?
 
Remembering ones that exit
Recalling their names
 
6:22 AM
@Sherlock9 Just recite over and over, "Befunge! Fish! Befunge! Fish!" And remember that "fish" is spelled ><>.
Also, this seems like a good time to plug my sort-of-2D language Ouroboros, in which instructions are indeed executed in a ring (actually one or more rings).
 
@Dennis - hmm why the stray "-" in the list I make here? (hence the near the right-hand end) - neither argument to the concatenation has it on their own, is it something to do with the dequeue, or have I misused niladic separation?

I hate how half the chess puzzles on this site are capture the queen, or get checkmate, and there isn't a distinction
 
7:41 AM
How do you know half are one type and half are the other if there is no distinction? ;)
there are 10 types of people in this world...
or was it 11?
 
Does anyone here play Atomas?
I made Atomas in ~130 lines of code!
Does Code Review have a chatroom?
 
@JonathanAllan the distinction is only made after you win or fail
 
@Qwerp-Derp Yes, the 2nd Monitor, I believe
 
how many bloody smothered mate problems are they going to give me?
 
@DestructibleWatermelon On lichess.com?
Go to chess.com, they have plenty of puzzles
Which aren't queen captures or smothered mates
 
7:57 AM
and then another one where the solution is to take all the pieces...
 
8:49 AM
major pieces*
 
9:23 AM
@DestructibleWatermelon Do you play Atomas?
 
I have not
Fairly sure this page is incorrect
The Immortal Draw was a chess game played in 1872 in Vienna by Carl Hamppe and Philipp Meitner. This game is the main claim to fame of both Hamppe and Meitner, and has been reprinted widely. The variation of the Vienna Game it uses was named the Hamppe–Meitner Variation in honour of the two players. The game was played in the 19th-century Romantic style, in which rapid development and attack were considered the most effective way to win, where many gambits and counter-gambits were offered (and not accepting them was considered slightly ungentlemanly), and where material was often held in contempt...
specifically
> but White spectacularly manages to force a draw by perpetual check.
 
Uh huh...
Is there a contradiction in the page or do you have another source?
Pretty sure perpetual check is basically the same as threefold
 
> A spectacular queen sacrifice, preventing White from playing Nc3 and Ka2, after which Black has insufficient compensation for his material disadvantage. The move forces the draw that follows.
@Qwerp-Derp I meant that white forced the draw
Black forced the draw by perpetual check
 
Ah
So change it then
 
9:39 AM
also "spectacularly" is probably not the kind of thing for a wikipedia article
 
Well, this sucks. I finally have a program for unlucky numbers that I know when U(1e6, 100) will finish for (unlike my previous versions which I wasn't sure would ever finish). The trouble is, that finishing time is projected to be about a month :')
 
I think the person who wrote the brief description didn't actually read the game
> This move is a crucial mistake, after which Black forces the draw in a breathtaking manner
 
You think someone is mucking about with the Wikipedia article?
 
Y'know, this page is just bad in general
 
Just edit out all emotions. Wikipedia is supposed to be a heartless source of information just like the rest of us
... :(
 
9:42 AM
Obviously the description was written by a Hamppe fanboy :p
 
@Sherlock9 day 29, power outage
 
This is an example volumetric rendering of an experimental algorithm to visualize points between random Attractors in a 3-dimensional space. It doesn't really serve any purpose, but looks pretty. This took about 50h to render (about 2.1 million points).

wtf why is there a quote section in the passed pawns page, and wtf even are the quotes?
    "A passed pawn is a criminal which should be kept under lock and key. Mild measures, such as police surveillance, are not sufficient." – Aron Nimzowitsch[3]
    "Passed pawns must be pushed!" – (unknown)
    "Black pawns travel faster than white pawns." – (unknown, popularly attributed to the Manhattan Chess Club)
 
9:59 AM
At any rate, the time limit is one day, not 35 days
I need to borrow a Linux system on which I can use pypy and seriously at the same time
 
Dual-boot then. Use something stupid safe, like Ubuntu and you'll be fine.
The current ubuntu setup even disables SecureBoot automatically if it's on and safely installs alongside Windows.
 
10:24 AM

yeah, bad meme
 
@mınxomaτ I used to dual boot but I messed up grub
Not sure how to reinstall it without messing with the existing but currently inaccessible Linux partition

> if you truly do believe in the "wage gap" then answer me why can't companies just hire all women, since they can get away with paying them less. they'd be saving a lot of money you know.

It's an interesting point: if women are being exploited in the workplace (in terms of lower wages), why wouldn't businesses exploit them more?

Does pypy3 work on the Windows Subsystem for Linux?
 
@DestructibleWatermelon /dʒiːɛmʌnpɹəˈnaʊnsə.bl̩ˈvɪli/?
 
@Sherlock9 I think the chain of thought is "men do better work" -> "pay the men more".
 
@quartata @PhiNotPi and some others, you may be interested in the new Lojban SE proposal on A51.
 
Obviously, the problem lies with the premise.
 
My friend's comments on that comment, translated and paraphrased:
- Lol that's actually what is happening in my hometown fyi
- Cigarette companeis in Kudus [a region of Central Java] only hire female workers to package their cigarettes
- And I believe in many places in Asia, women are "abused" that way
@Mego, I have installed Bash on Ubuntu on Windows. Says it can only find pypy not pypy3
 
12:07 PM

  Flags

Say anything and I'll make a flag out of it. You can also ask ...
 
@Sherlock9 Huh, interesting. So hiring women because they cost less does happen, just not (as much) in the USA.
 
Pretty much. Different social dynamics and pay scales over here.
 
@Sherlock9 Probably, considering how in the U.S. restaurant workers are legally allowed to be paid less than minimum wage with the rationale that the rest will come from tipping (I live in the U.S. myself, and I certainly think it's stupid)
 
As an example of a male-dominate industry (around Jakarta at least), the unskilled men can almost always find work as a motorcycle taxi driver (ojek / tukang ojek) even without a driver's license. Very few women do that around here.

MatsemannYou have probably seen these signs on the doors of various shops: OPENING HOURS mon-fri 0900-1800 sat-sun 1100-1530 The task here is to generate a sign like that, grouping days with the same opening hours, from a list of opening hours for the whole week. Input: 7 elements, represe...

 
Probably as they don't want to be on a motorcycle with a male passenger by themselves. Similar rationale with most other forms of transportation here (bus drivers, taxi drivers, personal drivers, etc.)
 
@ΛεγίωνΜάμμαλϠΟΗʹ Chicken
 
@Sherlock9 What boot manager do you currently use? GRUB or MBR? If it's MBR, it's safe to just nuke all non-windows partitions from the Windows Disk Manager
 
Last I checked it was grub
I'm trying to use WSL at the moment, but apt-cache only has pypy not pypy3
 
12:27 PM
@Sherlock9 Hm? Just download pypy and run it.
 
pypy is Python 2. pypy3 is purportedly Python 3
And I need Python 3 to run Seriously/Actually
 
@Sherlock9 Well, just download bitbucket.org/pypy/pypy/downloads/… and run the /bin/pypy file.
 
You keep using the word "just". I'm a Windows guy. I don't know most of this stuff
 
Thank you very much
 
12:30 PM
tar xf py*
to extract and then cd into the bin dir and run pypy ( ./pypy)
You might need to chmod +x pypy3.3-v5.2.0-alpha1-linux64/bin/pypy, but probably not.
If any command says you need permissions, use sudo .... To sudo the command you've just entered, use sudo !! (= repeat what I just did as sudo).
 
@mınxomaτ When you say the "bin dir", do you mean /bin?
 
Yes.

@Sherlock9 Do cd ~ and do everything again.
 
Again, most everything outside apt-get is news to me
Ah, found it. Whoops
Hallelujah!

Oh, the wonders of bootstrapping

On Ubuntu that'll install pip for python 2
Tack a 3 onto those pythons
 
Argh, I'm so used to arch...
 
I know it annoys the shit out of me too. I always get it wrong

@Doorknob what happened to the old one?
 
Hey guys, how do I paste the Unicode in an Actually answer into a Bash terminal?
Every attempt so far has lost me the Unicode characters
 
You don't.
 
Meaning?
 
You can create a file and read it, that should work.
 
Anonymous
@Sherlock9 I have no idea why that would happen. You could try pypy3 /usr/local/bin/seriously -c code (or wherever the seriously console script is installed - do which seriously to find out).
 
1:32 PM
@mınxomaτ Okay, I'm on Bash on Ubuntu on Windows
There is a small problem where I can't copy paste the Unicode
And I don't know where on Windows the files are kept
@Mego I installed it in the same place as pypy3
 
@Sherlock9 Just create a whatever.txt in any Windows directory with the code. Then launch bash in that directory and use yourprogram $(cat whatever.txt)
 
Found the Windows directory
Thank you, Everything
 
Does anyone remember those collaborative programming projects a few of us used to do? Like a checkers game and stuff? (@Doorknob I think you were part of it.)

@Mego Seems to work, but the darn thing doesn't seem to be running
Or does the file stuff work differently?
 
Well, my attempt to trick GitHub to serve huge files for free didn't work out so great.
 
1:46 PM
What happened?
 
They blocked the access, or rather the workaround I used.
But LFS is $5/50GB and then again $0.01/GB traffic. That's pretty expensive. Currently, I pay $5/m (traffic free <10TB) for the alwsl CDN (we served over 300 GB this month). But the connection is only a 100Mbps line, which chokes when many users access it at the same time.
