The Nineteenth Byte

wat

12:03 AM

i got home a while ago

ATaco

The main and worst reason I want to switch to Linux is usr/dict/words

Riker

cough mac4life cough

Pavel

12:21 AM

@Riker No. just.. no.

ATaco

I respect macs for what they are and what they are good for.

Riker

which is absolutely nothing

but hey they have a purty UI

Pavel

And \r line endings. *shudders*

Maltysen

duelingbook.com

^ HOLT SHIT I'M SO HAPPY

ATaco

Hey, I use Windows...

\r\n because single byte newlines are BORING.

Riker

12:24 AM

@Maltysen 10/10

quartata

You know the actual reason why that is right

Riker

but -2 for the intro thingy >_>

Pavel

Presumably, they kept \r\n line endings so they had their bases covered for documents made on Mac or Linux

Maltysen

@Riker its not actually up tho, the server crashed

Riker

lol rip

ATaco

12:24 AM

I'm still looking for an implementation that lets me use \r to just start typing over the same line, and \n to just move down one line.

Maltysen

@Riker and i was planning to stay up till 3:00 A.M dueling with people...

ATaco

The \r\n is actually a left-over from Typewriters and Early Printers, in which Carriage Return, \r, would simply bring the cursor to the start of the line, and Line Feed, \n, would bring the cursor down one, or, for a Type Writer, the Page would feed up one line.

Pavel

@ATaco Linux has that

quartata

@Maltysen What is this? All I see is get adobe flash

Maltysen

@quartata its a duelingnetwork copy by xtevens

since it got taken down

Pavel

12:27 AM

@ATaco I know where it comes from, that's my theory for why it's still that way.

ATaco

On some printers, specifying \r will just return the print head to the start of the line, meaning Some text\r ____ will print "Some Text" with "Text" underlined

Also, That's neat and I did not know it.

TIL that Linux supports \r in the best way.

Pavel

@ATaco You know those challenges where you have to animate something in the terminal? If it's only one line, \r is usually the easiest way.

ATaco

I wonder if I could convince my work's IT to let me install Fedora onto my computer...

Pavel

@ATaco Obligotory "Install Gentoo"

ATaco

No.

Riker

12:31 AM

@Maltysen they could probably add a cache setting for when you've already seen the intro

Pavel

Really old computers used to support \n the typewriter way.

Riker

really old computers used to be new

ATaco

Turns out it's easier to just not.

I mean, when do you really need to just move down one line, and nothing else?

\\\n\\\n\\\n\\\n\\\n\\\n\\\n\\\n\\\n\\\n

Pavel

There's probably some obscure golfing trick you could pull off.

ATaco

Diagonal line down and to the right.

Maltysen

12:33 AM

@Riker a) there's a skip button b) the chessy intro animations were one of the most famous things about duelingnetwork

Riker

ah lol

Pavel

Should I put custom scripts in /bin/ or /usr/bin/?

ATaco

/usr/bin/

Trust me, I can Unix well.

Pavel

I like how the message for Mego becoming an RO has one more star than the rest of them

ATaco

I couldn't redact my Mego vote to even it, so I added one to DJMcMayhem, to even it towards the other way

DJMcMayhem

12:53 AM

Lol

wat

I'm going to remake Reddit in Ruby on Rails

Wish me luck

DJMcMayhem

I still have one left for minxomat and me, so if it unevens out again I can help. :P

ATaco

Beautiful

Pavel

@wat Because you want to, or because you have to? RIP you either way.

wat

@Pavel Want to

Why? It seems pretty easy

Pavel

12:55 AM

Recreate reddit?

ATaco

Wh- Who unbalanced it! D:

wat

Rails greatly simplifies web apps

DJMcMayhem

Noooo!

I've already given mego one so I can't balance it!

wat

also, this won't be an entirely faithful recreation, it won't have things like subreddit sidebars or banning yet

ATaco

I've starred everyone and it's too late to unstar!

Panic!

wat

12:56 AM

@Doorknob please save us

Pavel

Still, there's a reason reddit takes more than one person to mantain.

ATaco

@Doorknob please re-balance the stars so we may feel joy!

wat

@Pavel yeah I know. This won't be anywhere close to the scale of reddit.

DJMcMayhem

I feel like pinging a mod about it is a little bit excessive

wat

@ATaco there I unstarred minxomat

Pavel

12:57 AM

You literaly said you're recreating reddit

ATaco

I didn't know he was a mod.

wat

@Pavel I meant that it will never get that big.

No scalability issues

Pavel

Well, have fun.

ATaco

2

There, I immortalized it

Pavel

Starboard is playing mindgames

Mistah Figgins

1:04 AM

@ATaco I'm tempted to star this...

ATaco

This is getting filthy meta

Mistah Figgins

"Oh wow, we better star a lot of inconsequential messages to get the announcements off of there!"

Pavel

This Star Wars is the real thing, man.

quartata

Can I get a mod to delete this room? I pressed the wrong button on mobile: chat.stackexchange.com/rooms/53293

(@Dennis)

LegionMammal978

@Downgoat Idea I just had: Because better golfers than I keep posting Mathematica answers, I should start golfing in Cheddar instead

ATaco

1:15 AM

Nah, Golf in RProgN instead.

091{w}: Just look at how cleanly it prints all the digits.

LegionMammal978

TIO link?

ATaco

Try it online!

Dennis

@Pavel Neither. Executables that do not come from the repos go in /usr/local/bin.

Downgoat

@LegionMammal978 awwww yisss :D brilliant idea

Pavel

@Dennis Got it, thanks

That's still in path, right?

ATaco

1:24 AM

Really, I just want to see someone else using RProgN.

Pavel

Ok, it is, neat

ATaco

Maybe if I wrote some actual proper documentation for it it would get more use.

Mistah Figgins

I would use it with documentation, I think

Pavel

That would indeed be helpful.

ATaco

The issue is I suck at writing documentation.

wat

1:29 AM

@Pavel Why are you using stock Unity???

get the Arc GTK theme at least

Pavel

@wat I switched to Linux last week

Pls man

Mistah Figgins

Speaking of, is this documentation sufficient?

wat

sorry

I can put together a package of things

Pavel

@MistahFiggins Yeah, that's pretty good.

Downgoat

@MistahFiggins I have an entire website dedicated for like 40 pages of docs and apparently that's not enough so I hate to say probably not

Pavel

1:31 AM

Cheddar isn't an esolang tho

wat

@Downgoat cheese is neat

Downgoat

wat

@Downgoat ...why did you send me a tank

Mistah Figgins

lol tanks

Downgoat

@wat XD tanks = thanks

wat

1:32 AM

kek

Mistah Figgins

nice pun

Pavel

kek indeed

Bah, someone star minxomat and Mego's things on the starboard

Mistah Figgins

Or I could unstar DJ's

wat

nooooooooooooooooo

Pavel

That was recent enough?

Btw @MistahFiggins, 21 hours left on that bounty.

Mistah Figgins

1:34 AM

mouse hovers suspensfully

@Pavel Oh jeez

LegionMammal978

@ATaco Is there any way to input directly onto the stack without a read?

Pavel

I'll probs create an indefinite one if it expires tho

DJMcMayhem

I don't think you can unstar after that long

Mistah Figgins

@Pavel ok then, I might not have time

School stuff

Pavel

That's fair

Mistah Figgins

1:35 AM

On the other hand, it's cool school stuff

Pavel

That's always a plus

Mistah Figgins

I get to write code for a multiplayer board game for a project

One that already exists irl

Downgoat

I once wrote a regex to parse valid XML, does anyone happen to have that link

Pavel

@Downgoat That is not possible

Downgoat

haha yes it is

Pavel

1:37 AM

No, XML isn't a regular language

You can't parse it with regex

Something something chomsky

Downgoat

@Pavel realllly.....

;)

wait that's XHTML

Mistah Figgins

Oh geez, now mego is short a star...

Downgoat

also here's a tokenizer for cheddar

Pavel

html vs Regex

Downgoat

@Pavel 99% of regexes do not conform to definitions of a regular language

ATaco

1:41 AM

@LegionMammal978 Command Line Arguments are defaultly on the stack, Quoted words push strings, and Numbers push numbers.

Mistah Figgins

@Downgoat "sane regexes" is an oxymoron is some senses

Downgoat

A* or A+ is something like A' -> A' A | A

@MistahFiggins see update

regular expressions are turing complete though depending on flavor obviously though

Pavel

What version of regex is turing complete?

Downgoat

@Pavel idk, pretty much all of popular ones

wat

@Pavel Please sudo apt-get install git

Downgoat

1:44 AM

I think for sed & grep you need to use extended regex

Pavel

@Downgoat PCRE doesn't even cover context-free

Downgoat

@Pavel of course it does

(?R)

Pavel

Perl6 patterns are context-free

Downgoat

(?<DEFINE>) outlines your non-terminal productions which is followed by your start

ATaco

My one and only (Personal) test for Turing completeness is to interpret Brainfuck.

Mistah Figgins

1:45 AM

@ATaco GOL works too

*For me personally

ATaco

Brainfuck is usually easier to interpret.

Mistah Figgins

Yeah

Pavel

In regex tho

ATaco

You don't Have to output characters.

Downgoat

Still I parsed XHTML in regex so I win

Pavel

1:46 AM

Regexes always halt therefore cannot be TC

QED

Not always.

Always

(?R)

Ok, what's that?

Recurse.

1:47 AM

@Pavel what this is not true

where did you get this idea

please refer me to whoever told you this bogus claim

Pavel

this guy

ATaco

Also, the timespan of the universe may be finite, in which case, the Universe is not Turing Complete. As Turing Completeness (Loosely) defines the ability to Simulate a universe, given enough time, Turing Completeness does not necessitate a non-halting option.

Downgoat

@Pavel that guy does not know what he is talking about please downvote his answer

Pavel

Read all the answers to the question, no one thinks PCRE can be TC

ATaco

Also, When in Doubt, Use Retina

Downgoat

1:50 AM

@Pavel i know 2017 is weird year for facts but we were talking about CFG

Pavel

The accepted answer clearly states PCRE isn't a CFG

Downgoat

also refer to @MartinEnder for regex's turing completeness

@Pavel I know 2017 isn't a good year for facts but accepting something doesn't make it true

I have just proven to you it can emulate any CFG

Pavel

That is true, but I'm more inclined to believe the guy with a green checkmark and a score of 24

Downgoat

that guy has 2K rep

i have lots more green checkmark and score

though come on

1 min ago, by Downgoat

I have just proven to you it can emulate any CFG

Pavel

Really?

Downgoat

1:53 AM

pls

Pavel

How?

Downgoat

8 mins ago, by Downgoat

(?<DEFINE>) outlines your non-terminal productions which is followed by your start

wait I don't know if a symbol in a regular grammar can be a non-terminal but not related to current discussion

Pavel

I'll leave this here and be confused for the rest of the day

Downgoat

He is trying to say you shouldn't

I mean anything is possible if you are dedicated enough PPCG contestant :P

wat

is retina tc

ATaco

1:58 AM

/(?R)/ does not halt.

And yes.

Pavel

@wat Yeah

@MartinEnder you know a lot about regex right? How is it that everywhere I turn, I'm told you can't parse HTML with regex, and yet Downgoat appears to have done so?

regex101.com/r/fxMtVS/1

Downgoat

^ Is expandable if I missed something

Will fix if you find any bugs

speaking of which, I should learn how to make regex engine

wat

4426

A: RegEx match open tags except XHTML self-contained tags

You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. As I have answered in HTML-and-regex questions here so many times before, the use of regex will not allow you to consume HTML. Regular expressions are a tool th...

Downgoat

looks like you need bottom up approach with somehow identifying terminals which seems to require solving halting problem

@wat I know, I even have shirt :P

wat

@Downgoat Cool

Mistah Figgins

2:13 AM

Five straight minutes of cringey fish puns

Oh god

wat

@Pavel

Pavel

Ye

wat

I just spent a pretty long time putting together this script

please run it

Pavel

Is it ok if I'm a little scared?

wat

yeah, you can read the script

Pavel

2:17 AM

So, where's the script?

Maltysen

what's an excuse to get IT support to attempt to fix something?

it needs to be believable

ATaco

"Hey, Can you fix this?"

Pavel

@Maltysen You have a report due by the end of the hour

Maltysen

no lol

wat

@Pavel one sec uploading

Pavel

2:18 AM

The piece of tech is absolutely critical for that report

wat

@Pavel u.dk0.us/install-theme.sh

Pavel

Gah, installing emacs made it my default text editor

wat

use vim

Pavel

I use atom

wat

aka the editor for snails

Pavel

2:20 AM

Eh, dennis told me about it so I tried it out, never saw a reason to switch to anything else

wat

ok, it's your choice

Helka Homba

In case any OPPCGMCS players are in here: chat.stackexchange.com/transcript/message/35314251#35314251

Pavel

BTW, is there an easy way to switch back from your script?

wat

@Pavel It doesn't change anything by default, it just installs the themes into ~/.themes and ~/.icons

Pavel

Oh, ok

wat

2:22 AM

so just running it will not change anything

Pavel

I'm installing the dependencies rn

wat

ok

Downgoat

I made super-advanced graphic for my blog:

Pavel

that is a problem with linux things for some reason

I should have used cp, but it's fine

Pavel

2:49 AM

@wat no errors!

wat

@Pavel yay!

Pavel

How do I switch themes?

wat

now relog and sudo apt-get install unity-tweak-tool

Pavel

Restart or is loggin out/back in enough?

Actually, I'll just restart real quick

CRAP I HAD AN UNSAVED ESSAY OPEN

wat

@Pavel Why not use Google Docs?

Christopher Peart

2:53 AM

@DJMcMayhem Nice job on becoming a chat owner!

DJMcMayhem

@ChristopherPeart Thanks! I'm honored :D

Pavel

@wat I might switch, I can't get MSO to run with wine, and LibreOffice is... not great.

So, how do I switch themes?

Christopher Peart

@DJMcMayhem I voted for you

ATaco

Also, I'm writing an RProgN Tutorial.

wat

@Pavel OK. I've only had good experiences with Google Docs. MSO 2010 and below works perfectly in wine. LibreOffice recently received a major update, you might not have it yet.

sudo apt-get install unity-tweak-tool

ATaco

2:55 AM

Maybe someone will finally be able to understand it!

Christopher Peart

(and a one-two others)

Pavel

Ok, did that.

@wat Wine 2.0 supposedly supports 2013

But the installer fails

wat

Go to terminal and unity-tweak-tool
