@aditsu If you select the lines after typing, a button appears "fixed font". Click it.

lol @ "do not attempt to perform calculations yourself"

aditsu

@mbomb007 I remember seeing that button but didn't know when it appeared, thanks

You can also Ctrl-k for that.

unicode-art That is what I need for this challenge.

art-art

Dennis

7:33 PM

@AlexA. Why the conditional? {∇1}1 should achieve exactly the same.

interpretive-fingerpaint-art

art-art is not art anymore, you know, multiplying two negatives results in a positve.

@Dennis Oh yeah? Didn't know. Thanks!

@AlexA. Should I let people use these:

Box-drawing character

Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. In graphical user interfaces, these characters are much less useful as it is much simpler to draw lines and rectangles directly with graphical APIs. Box-drawing characters work only with monospaced fonts; however, they are still useful for plaintext comments on websites. Used along with box-drawing characters are block elements, shade characters, and terminal graphic characters. These can be used for filling regions of the screen...

No because I don't think all languages would be able to

7:35 PM

Or should they just use the usual + - |?

Best to restrict ASCII art to ASCII.

I think it is only the esolangs that do not support unicode...

Well we wouldn't want to exclude them.

Wouldn't we?

@Dennis Crossed out 8 looks like regular 8. :(

Dennis

7:36 PM

Do you consider TI-BASIC esoteric?

@flawr Why would we?

Pretty much, yes!

@AlexA. Not for me.

8

Hm

I like box drawing personally. I grew up with BASIC, so the "extended ASCII" code pages were fun to play with before all this unicode stuff got popular.

7:37 PM

At least the versions where you do not have to close the parentheses.

Dennis

@AlexA. You could add a NBSP to each side of the 8.

Eh. Don't care enough.

I just think the +-| does not look as pretty. Or is there another method that would make the labyrinths look prettier, that only uses ascii?

You could just say ansi-art instead :)

I mean if you only allow ascii you also exclude all germän prögrämming längüäges.

7:39 PM

Not ASCII source, ASCII output

ANSI art

ANSI art is a computer art form that was widely used at one time on BBSes. It is similar to ASCII art, but constructed from a larger set of 256 letters, numbers, and symbols — all codes found in IBM code page 437, often referred to as extended ASCII and used in MS-DOS and Unix environments. ANSI art also contains special ANSI escape sequences that color text with the 16 foreground and 8 background colours offered by ANSI.SYS, an MS-DOS device driver loosely based upon the ANSI X3.64 standard for text terminals. Some ANSI artists take advantage of the cursor control sequences within ANSI X3.64 in...

Well extended ASCII would have all those nice characters.

Pro tip: Quitting the Dyalog desktop program does not stop the running Dyalog system process if code is still executing. So in short, don't run my infinite loop code. :/

I was thinking, "Why is my fan going nuts? I'm barely doing anything." Then I looked at the system processes. Dyalog, 99.9% CPU.

Finally finished my JS interpreter for Recall: run.codegolf.xyz/…

Is it fully complete? A total Recall?

7:46 PM

It is the absolute recall.

minxomat, is there a documentation about the features of codegolf.xyz?

codegolf.xyz links to PPCG

codegolf.xyz/readme.txt

@flawr

why don't you make the base domain link to readme?

The base is a catch-all rule for every other link. e.g. codegolf.xyz/users

7:51 PM

so can do some code and see if nothing else is being hit, just redirect to readme

so if requestURL == "codegolf.xyz" then redirect to "/readme.txt"

Hi

So I know you can run Scala IDLE-style, but does this count as a complete program? codegolf.stackexchange.com/a/59379/14215

Try it

I don't have scala installed. IIRC, to run it from a file, it needs more (object setup boilerplate). If run from IDLE, I know it works.

The 301s are served by the Nameserver. They don't hit my servers. I usually use the base domain on mobile / someone else's PC to get to the site quickly. So I'd like to keep it that way.

7:53 PM

So I'm asking if that counts as "complete", not if it works.

@Geobits ansi-ansi

ass-key

an-c

@Geobits If there's required boilerplate then I don't think it counts.

Well, that answers that.

Huh.

8:02 PM

Regarding my infinite loop question from earlier, it's if this Perl code counts as a loop:

`$0`

What does it do?

The ` ` run a command, while $0 contains the filepath of the perl script.

So it runs itself?

Presumably repeatedly?

It actually opens up the script's file in Notepad, but the Perl process doesn't actually terminate.

Hm.

8:04 PM

Since it is waiting on the return value of the command that was run.

So it isn't looping so much as waiting.

I don't think blocking counts as looping.

But if I thoght it should be a loop?

Yeah, it sounds like that doesn't count for this challenge.

And the loop should not do anything, this loop actually does something.

8:05 PM

Well the loop can do whatever, it just can't print anything.

That's how I interpret the challenge, anyway.

It appears to terminate the process once the newly-opened file is manually closed.

Is there any way to make ascii art visible ina nice way heree on SE?

Besides using the code font?

@PhiNotPi But it isn't looping in the usual sense, right? Just waiting for something.

Probably

8:08 PM

@Geobits Yes, the code markup just tears everything vertically apart.

Less vertical space would be nice.

I don't think there's a good way to change that :(

If you ignore the window that pops up, it appears the same (from looking at the command prompt) as a normal infinite loop.

@Geobits Any bad ways?

@flawr Screenshot :P

@PhiNotPi Isn't that true of opening any GUI program from the command line?

Basically.

8:10 PM

Calling it a loop seems like a stretch to me, even though I guess there's an input handling loop internally running.

`perl $0`

is a program that runs itself

That makes more sense to me, just like a recursive function would.

Fun fact: letting that run and then doing the Ctrl+C to terminate it prints one "Terminating" message for each process started.

Nice.

Did you lose all of your stuff?

Are you going to try to set up dual boot again?

I have backups of my documents

I might.... maybe not ElementaryOS

(even though I thought it was nice)

8:48 PM

I'd say try it again. It's unlikely to happen twice. Surely it wasn't the fault of ElementaryOS but rather some Dell hardware.

TempleOS?

It looks like the only thing they did was replace the harddrive

That doesn't make up for the fact that it's manufactured by Dell. :P

intercaloninterstates.org

They have to be trolling.

I had a dream that Brian Tompsett actually said something in here.

Complexity happens.

Gotta learn to deal.

8:57 PM

Is there any principle or rule that applies to things like this:

1 2 3 4
2 3 4 1
3 4 1 2
4 1 2 3

That kind of thing

Cyclic permutations?

I have no idea; maybe.

I mean, that's what those are. The animation suggests something else may be going on, perhaps.

Think this would be fun? -> Given all Brainfuck programs of length N, what percentage (a) have runtime errors, (b) halt, or (c) don't halt (in some preset time limit)?

@El'endiaStarman That's my animation

8:59 PM

@ZachGates Ahh, okay. Why did you animate it the way you did? Like, what was your thought process?

@Calvin'sHobbies So you have to write code that executes the BF code and figures out what happens and keeps statistics?

@Calvin'sHobbies I don't think a for-loop is very appealing. BF implementations are pretty much already there for every language.

@ZachGates The rule is that you are cycling the numbers around. What else are you looking for?

Love, in all the wrong places.

@AlexA. Yeah, then output the 3 precentages

9:00 PM

@El'endiaStarman First I enumerated the left most row and column, from 1 to n, where n is the row/column length

Then I moved to the next leftmost, empty row/column and repeated from the above/left element

Yes; sorry. It scrolled as I clicked the arrow.

Story of chat.

@Calvin'sHobbies I didn't even notice the left-shift of rows, haha

@minxomat Ok, but the percentages for different N is the interesting part (I think). It could be open to any test language, not just BF. (Chaitin's constant made me think of this but that prefix-free stuff looks too complex for here)

@Calvin'sHobbies But 90% of the code will be taken up by the BF eval function. The stats are trivial. I just think that this is not different enough from "just write a BF interpreter".

Here's another way to look at it:

  | 0 1 2
----------
0 | 0 1 2
1 | 1 2 0
2 | 2 0 1

(x+y) % 3

9:06 PM

also ((x ** 3) % 3) + y

That's...significantly more complex, but sure. :P

How does one loop in Ostrich?

no idea

Haha

So says the creator of the language

9:29 PM

How many times will I have to tell you it's abandoned? :P

However many times it takes for you to get tired of reiterating that it's been abandoned and decide to keep working on it.

Alright, so infinitely many.

There's no esolangs.org Ostrich page. What's special about it?

IT'S THE BEST LANGUAGE.

Is it some creative programmatic interpretation of "putting your head in the sand"?

9:33 PM

^ just breaking the blue streak!

@El'endiaStarman No

AH.

> The name "Ostrich" comes from golf, in which it means a score of 5 under par (which has never been achieved).

It is wonderful and does all things.

Disclaimer: I've only ever used Ostrich once.

The framing "protection" in stack snippets is pretty useless as it loads the whole frame content and then tells the user framing is not allowed...

^

9:43 PM

@minxomat So? The point of disallowing frames is to prevent "click hijacking," i.e. the frame "stealing" a user's click when the user expected to click on something else.

Peter Taylor

FYI I'm going to be on holiday for a week, so my absence from the site does not imply that I've died.

9

@PeterTaylor it's not mutually exclusive, though

@Doorknob Then strip the code before executing it and don't load the frame at all.

@minxomat Huh? What do you mean by that?

Are you referring to putting SE sites in a frame?

That reminds me, there was a really nice talk at Defcon this year about preventing clickjacking...

9:46 PM

@PeterTaylor I'll miss you. :(

Is linux.com a reliable source for linux stuff?

@Doorknob Yes. Why does it load all the content and display it just to alert the user the empty it again. It could be implemented better.

@PhiNotPi No, use Yahoo Answers.

lol

@minxomat How else would it work?

This isn't a Stack Snippets-specific feature. It applies regardless of who's framing it.

Peter Taylor

9:47 PM

@PhiNotPi If I don't show up within two weeks, enquire about the funeral.

@PeterTaylor moreover, not going to school gives you better chances of living.

I was just looking at this list on their site: linux.com/news/software/applications/…

@PeterTaylor Will do.

> There is there no doubt elementary OS is the most beautiful Linux-based distro

because that's totally not completely subjective

That entire article is... bad, to say the least.

There is no such thing as "best desktop distro" -_-

yeah, I was like "this just seems like some low-quality news site"

Also they use Joomla. I wouldn't trust them :P

9:52 PM

Use Unix.SE

It's a step above Yahoo Answers.

They have an article titled "How to Install and Try Linux the Absolutely Easiest and Safest Way"

Step 1. Have an IT professional do it for you.

In the spirit on this challenge, I've got a joke for you:

Pete and Repeat were in a boat. Pete fell out, who was left?

The other guy, whose name was unfortunately "Repeat," was still in the boat. Do not take this as an opportunity to repeat the statement. :P

It's a pretty funny joke to tell your friends. :)

@Doorknob Yes it has.

@AlexA. I don't think Windows 7 does.

As in, I had to install it.

10:20 PM

@ZachGates Because it's asking for list comprehension syntax

The other answer stole their code from a commenter..

@PhiNotPi Yeah, 7 doesn't IIRC because I had to install it on my VM

But I think the newer ones do

@AlexA. I didn't even notice that

@ZachGates Welcome to Stack Overflow

it's the natural code to write

10:21 PM

@ZachGates I guess because it's less efficient than a list comprehension

but not by much...

i think the poster might have written it independently, and it is a bit different

@AlexA. And then someone commented back to me that stealing code from a comment is OK

> stealing code from a comment

@Doorknob Using any should be just as efficient (if not more so) than a comprehension

What are you ... 5?

10:22 PM

@ZachGates Doesn't look stolen to me...

@ZachGates filter + lambda is slow

did the infinite loop challenge just get 5 reopen votes within minutes?

or did someone do some magic?

@ZachGates It actually is different from the comment.

@Doorknob ??

By an == 0

@xnor Magic

@xnor Magic is always involved

10:24 PM

@ZachGates And a not

@ZachGates Still doesn't seem like he stole it.

And he said that he didn't. I'm inclined to believe him. I've posted code on SO that ended up being nearly identical (or at least functionally so) to code posted in comments that I didn't see.

what's the shortest haskell function to convert a bool to number?

so, True to 1, False to 0

the best I have is 12 chars and it's weird

(No idea how typing in Haskell works, but) if a variable is boolean valued, can you use it in mathematical contexts and rely on automatic true->1 false->0 conversion?

no, haskell is very strict about types

python's automatic conversion is very useful in golfing

Most of the languages I know either convert automatically or don't have a concept of boolean values. Haha

that's why i'm hoping for a short expression to convert it

What is it that you have now that's 12 bytes?
