Backward compatibility. Windows is backward compatible with MS-DOS (aggressively so, even) and MS-DOS used the CR-LF convention because MS-DOS was compatible with CP/M-80 (somewhat by accident) which used the CR-LF convention because that was how you drove a printer (because printers were origin...

Newline

In computing, a newline, also known as a line ending, end of line (EOL), or line break, is a special character or sequence of characters signifying the end of a line of text and the start of a new line. The actual codes representing a newline vary across operating systems, which can be a problem when exchanging text files between systems with different newline representations. The concepts of line feed (LF) and carriage return (CR) are closely associated, and can be either considered separately or lumped together. In the physical media of typewriters and printers, two axes of motion, "down" and...

The fun thing is that in every mechanical typewriter that I've ever touched, the line feed and carriage return was combined.

Probably too young

The last one I used had a lever for line feed and carriage return was automatic in that pushing the lever would send the carriage back to the start, but you could hold it still and perform a lone line feed.

You can live with me if my cat doesn't kill you.

PowerShell treats \r\n and \n the same when reading files. And you can use (and PowerShell will understand) just \n when writing out to files. Finally. Microsoft is slowly moving toward \n as the standard, but it takes a long while.

@EasterlyIrk Cool, I can try to bring some european mice for your cat to try=)

Technically `n since PowerShell has to be different, but whatever.

@EasterlyIrk What area do you live in?

@TimmyD PowerShell has much worse problems with linefeeds ಠ_ಠ

Oh, yeah. Linefeeds everywhere.

You get a linefeed. And you get a linefeed. ...

O.o we are close to 2030 than to 2000. !!

we're also closer to 3030 than to 1000. crazy innit?

Which is not true for the other two dates.

I thought you were saying we are closer to 22:19 than we are to @TimmyD

9:20 PM

I doubt that.

I've never been compared to time before. I'm not sure how I feel about that.

Actually "we" is closer to "22:19" than "@TimmyD" in Levenshtein distance.

@Zgarb As I said, it heavily depends on the metric=)

@TimmyD It's actually insane how much effort this problem took to solve though.

Well, if you stay within the PowerShell walled garden, everything is fine. ;-)

I mean, that's what you get for using Ruby. :p

@TimmyD that kinda defeats the purpose of a command-line...

@TimmyD you can't imagine how annoying this actually is when golfing with esolangs, where a trailing linefeed usually breaks your program

Yeah, I believe you. Since 99% of my answers here are solely PowerShell, and >99% of code I do for $DAY_JOB is solely PowerShell, I've not really run into it.

@flawr That's pretty cool. On the other hand, I see now why using HTML tables for layout got such a bad rap.

Well the other thing is that it helps if you really use the correct html tags depending on the content. This makes it much easier for non graphical interpretation of the website

E.g. for crawlers or for blind people.

If you go to my website and look at the source, you'll see that I have alt-text for basically every single image. For that reason.

Is there a difference between <_< and >_> except the chirality?

Chirality

Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek, χειρ (kheir), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called enantiomorphs (Greek opposite forms) or, when referring to molecules, enantiomers. A non-chiral object is called achiral (sometimes also...

@CᴏɴᴏʀO'Bʀɪᴇɴ Minkolang doesn't have a map, or a way to do functions other than using F f. So, loop through the stack and use xyF to jump to x,y in the codebox, and f to return.

There's a good chance you'd be better off just putting the "function" in the loop.

@CᴏɴᴏʀO'Bʀɪᴇɴ I do not really get that "smiley" anyway.

@El'endiaStarman Oh, okay. Different question: how do I detect of there are three consecutive 1s on the stack?

If there's any built-in for that, it'll be in "Grouped: Lists and Strings". I'm looking there now.

9:48 PM

@flawr They're both of suspicion.

I thought it expresses about something similar as facepalm.

Like so.

That is a bug I need to fix. Probably a one-off error.

Also, the loop can be a little smaller.

10:01 PM

oh?

You can use c to copy an element at a specific place.

Where is this mystical element copied to?

top of the stack

You can use negative indexing like Python.

oh

so 1~c would copy the second-to-top element of the stack to the top?

1~ for -1. And I think it would copy the top element.

yep

Implode the Box code-golf ASCII boxes look like this: ++ +---+ +------+ +---+ ++ | | | | | | | | | | | | +-+ | | | | | | +-+ | | | | | | +---+ | | | | +--+ | | | | | | ...

Hmm. The only way it could give a false positive would be to have 0 0 0 1 1 1 on the stack, right?

That's true...

Which would mean the input sorted would have to start with 1.

10:19 PM

Like this?

But to get 3 consecutive diffs of 0 would mean 1 1 1 1 2.

Wait, if the input is sorted, you don't need to sort the diffs.

The input isn't sorted.

And using 2~c apparently eliminated the need to pop off the top.

$ns yes it is

oh

d'oh

Oh wait, the bug makes it so the top of stack is not included in the search.

And the top of stack is indeed the smallest number in the input.

oh wait, you do need to sort the diffs to handle 1 2 3 3 4.

10:25 PM

Oh, darn.

And what I said earlier about taking out x and 0 doesn't work.

ooooops

Oh, and an input of 1 2 3 4 5 gives 2, which very conveniently works because all that's needed is a truthy value. :P

11:22 PM

err I was not nearly specific enough

I thought so=)

I want the function to be its own inverse and to never give f(n) = n

So an involution?

Actually it doesn't need to be an involution

just easy to invert

Well you can always swap two numbers

(1,2,3,4,5,6....) -> (2,1,4,2,6,5,...)

11:24 PM

Something like 1<->2, 3<->4, etc.

But I'm hoping for something shorter

shorter in what way?

in Python ;)

What about n -> -n + 1?

That's not positive.

> positive integers

Another ninjenga

11:26 PM

ah, whoops

f(n) = n + 2*(n%2)-1 does the swapping thing.

(n-1)^1+1?

That is the identity?

Er... bad precedence there

n=>n%2==1?n+1:n-1 in javascript, quite short, I do not think it is much longer in python.

No, actually, he xor'd it.
