5:01 PM

I hate it when I hit enter in the middle of typing

Don't we all.

The US keyboard Enter still gets me.

Q: name me a standard/way of doing sth that is not an official standard but it's very common and i'm probably using it all the time

office documents

the standard is openoffice

I should write an ascii-art challenge and help you out with a V answer to get more comfortable with it

Right now, I'm looking at the "Add two numbers" challenge to see if I can do it

5:04 PM

Ohh, I think I've already answered that one in vim

Or maybe that was the divisibility test

I'm still going to try :)

I just checked. No vim answers yet. :)

@betseg Me when I was learning Processing. I though I had it all, then I realised that I still had to learnt the various libraries...

@KritixiLithos Are you going to do it in V or vim? Cause vim probably needs at least 8 strokes, but there's a two byte V answer

Wait no, vim can do it in 6

5:11 PM

I'll try vim first, then V

Speaking of DJMcMayhem's challenges, Goodness Giza Golf needs an accepted answer while I'm still eligible for the gold badge. :P

Nevermind, 5

I keep thinking of golfier solutions

@Dennis I don't know... I kinda recently hit a point where I feel like accepting doesn't make a whole lot of sense for code-golf challenges, and I haven't accepted one since

4

I don't know if that's a permanent thing or just for the moment

:( Bye bye, badges.

El'endia Starman

@betseg I had a similar reaction when I answered python questions on Stack Overflow. The vast majority of questions were either basic ones that could've been answered with better Googling or were questions regarding some popular Python library that I knew [almost] nothing of.

@Dennis oh come on... You can get badges other ways. :P

Accepting still definitely makes sense for other challenge types, like code-challenge, fastest code, or especially koth

5:17 PM

True, but Populist badges account for 29% of my gold badges. They're the only way I have to keep up with Calvin. :P

And it would have been my second Populist on one of your challenges. For some reason my Python answers to your challenges are more popular than usual.

El'endia Starman

@Dennis This calls for a statistical analysis!

(I'm not doing it though.)

Maybe because they're really good. :)

To the lab!

ddC<C-r>=<C-r>"+<C-r>1<ENTER>

I think you're missing the eval register

5:20 PM

Whoops

added it

So input is on two lines?

Yes

One thing you can do to shorten it is to build the "a+b" text before deleting/evaluating it.

So Jr+0C

J conveniently puts the cursor on the space

I see

How do you do it in V?

5:39 PM

@KritixiLithos À<C-a>

Register a is predefined with arg 1, and À is equivalent to @a

I get it now

What's the hex value of <C-a>?

@El'endiaStarman That would be like using Photoshop to perfect your hairdo :P

we'll get design with the new year right?

El'endia Starman

@betseg As Geobits has decreed it, so shall it be.

yay \o/

5:53 PM

@KritixiLithos 0x01

You can insert it into a vim buffer with <C-v><C-a>

@El'endiaStarman impressive how geobits manages to trick people even when he isn't around. ;)

El'endia Starman

@DJMcMayhem It's really amazing, isn't it?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem I recently came into possession of a dr seuss hat, want it? just as a gift

@betseg that's a joke >_<

@EᴀsᴛᴇʀʟʏIʀᴋ lol i managed to troll one

@EᴀsᴛᴇʀʟʏIʀᴋ on tf2?

Sure! Like I said, I don't play it very often, so someone else might appreciate it more, but that sounds good to me!

@DJMcMayhem You know mine needs to be chosen ;)

6:06 PM

Huh. You can build a pretty good Redis replacement for low-traffic KVS just using the GitHub API. That's awesome.

@ETHproductions wat, you don't do this?? :P

Does anyone have thoughts on this before it goes to main in 20 minutes?

A: Sandbox for Proposed Challenges

Can I sweep the mines? code-golf grid game Minesweeper is a popular puzzle game where you must discover which tiles are "mines" without clicking on those tiles. Instead, you click on nearby tiles to reveal the number of adjacent mines. One downside about the game is that it is possible to end...

btw, i upgraded tio client dark mode (i think)

sick

@Downgoat Well, now it has the bright flash during load, like Doorknob feared.

6:09 PM

oh no D:

That does indeed look letter than before. The green run button doesn't really combine with the theme though.

i don't want to use PHP to fix though >_>

Fyi, you're violating Twitter's brand guidelines.

i guess that's best solution

@Downgoat That's what it was made for.

El'endia Starman

6:10 PM

@DJMcMayhem Add decision-problem.

Just use the request parameter to switch between two served CSS files. That is in fact less code than using JS for layout.

PHP scares me in all honesty

PHP is one of the easiest language to use.

I'm 99% sure it was some originally homework assignment mashed together the night before it was due :P

@mınxomaτ JS is easy but not good according to many people here

You don't have to use PHP. Any language you can run on your server will do.

6:14 PM

A good practice is to include resources into the served pages instead of including dozens of script tags in the HTML. That speeds up page load times tremendously.

El'endia Starman

@mınxomaτ You mean like inserting JS code into the page just before it's served to the client?

Yes.

Every request to any server adds latency.

El'endia Starman

Hmm. Wouldn't even be that hard to do with Django['s templating engine].

Bash ftw.

You can just echo the CSS into the page like this: echo file_get_contents('css/'.(isset($_REQUEST['d']) ? 'dark.css' : 'normal').'css');

6:17 PM

shouldn't I just modify the URL of a link rel="stylesheet"?

that way browser can cache and all

But it will always load slower the first time.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem yeah

El'endia Starman

@mınxomaτ I'll definitely try to keep this in mind if I work on any project with large amounts of CSS or JS.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Can you go online for steam?

@El'endiaStarman The practice is called amalgamation.

Google also uses that on basically any page. Also referenced in one XKCD.

6:20 PM

Caching small files is overrated. TIO Nexus (excluding the language list and DEFLATE) fits in 33 KB (9.2 KB compressed). Any potential speed gain from caching bits and pieces of it is nullified by the additional requests you have to make.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem google how to set a steam trade URL and send it to me?

....so, when's the showcase going to be reopened? :P

question: am i doing this best way:

<VirtualHost *:80>
        ServerName vihan.org
        ServerAlias www.vihan.org
        ServerAdmin vihan@vihan.org
        DocumentRoot /var/www/vihan.org/public_html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        AddHandler application/x-httpd-php .html
</VirtualHost>

There's not really anything there to be wrong :D

Though because many longer requests can be run against your site, nginx is the better choice. But for now, Apache should be fine.

AFAIK nginx + ghost works better too... I should of thought this through better

6:23 PM

You current VHost is pretty trivial. It's basically the same, maybe even less, in nginx server blocks.

wait, how would the server know to serve dark mode?

I don't want to use query params for such

Session variables?

Cookies?

localStorage

^ no

@EᴀsᴛᴇʀʟʏIʀᴋ Do I need to use scrap.tf?

Nvmd, I figured it out. I sent it to you on steam

Eᴀsᴛᴇʀʟʏ Iʀᴋ

6:29 PM

Kk

@EᴀsᴛᴇʀʟʏIʀᴋ Just got it. Thanks!

> tend to have long, not short, answers

Not very true for our site :P

I strongly disagree.

Answers like: <language>, <bytes>, <code> are extremely boring, and rarely get my upvote

A challenge that can be solved in a couple of bytes isn't very interesting.

Also, that.

El'endia Starman

Golf your code, not your answers.

7

6:38 PM

@TuxCopter idk not as persitent

Even worse: <language>, <bytes>, <code>, "30 characters needed, you entered 14"

@Downgoat Then cookies

@El'endiaStarman code = answer?

oh

@DJMcMayhem Yeah, consider padding your answer with something interesting, like a permalink or an explanation.

Or account preferences stored server-side

6:39 PM

Or a gif. :)

Um, no, not that.

@DJMcMayhem Thankfully, I don't have to worry about that in C#/Java :D

@Dennis Why not? I golf in vim, where gifs of the program executing are really relevant and interesting

It's not that I don't like GIFs in answers, but I'd very much prefer a link to them than an inlined animation.

@TuxCopter but cookie are hard to use :(

6:41 PM

@Downgoat What?

localStorage

very difficult to change and all

I did it!!! I figured out why my COW code yesterday didn't work and I fixed it!!!!

Even with JS it's simple

i mean they are giant string

like wat

6:41 PM

And server-side it's generally an hashtable if you use a good framework

who cmae up with this idea

@TuxCopter database = overcomplicated

@Downgoat A smart guy

no

The format is actually pretty simple

@Downgoat wat?

yes, but it's dumb

6:42 PM

SQL is way too simple

El'endia Starman

@Downgoat Probably someone looking for a quick solution that would work for now.

@Downgoat ?

9 times out of 10, localStorage is better than cookies.

The cookie format is not dumb

user image

@TuxCopter why is it not object

@Dennis yeah but cant get localstorage on server side

6:42 PM

(ノಠ益ಠ)ノ彡┻━┻

@Downgoat Well, duh.

Its more like 99 times out of ten

@Downgoat You want to use the data client side or server side?

@DJMcMayhem In your challenge, what's the difference between X and *

Do it clientside

6:43 PM

@TuxCopter both

Client side google 'parse cookie js' and get a stellar answer from Jon Skeet explaining the thing and server side it's usually very simple if you have a good framework

El'endia Starman

@TuxCopter Downgoat is trying to serve up a light or dark CSS theme based on which the user would prefer to have.

brb importing giant 50KB cookie library labeled "only 25KB gzipped" made by a guy who used w3schools for their JS education

El'endia Starman

It's quicker and more efficient to put the CSS in the HTML being served rather than loading it afterward with JS.

@Zgarb I just realized that I confused the two. I'm going to take out X completely

Asterisks are known mines now

6:44 PM

nvm

:33891299 this exactly fits my given sterotype above XD

A: Javascript getCookie functions

The function from W3CSchool is wrong. It fails if there are multiple cookies that have the same suffix like: ffoo=bar; foo=baz When you search for foo it will return the value of ffoo instead of foo. Now here is what I would do: First of all, you need get to know the syntax of how cookies are...

@DJMcMayhem Ok good

Is that better now?

@Downgoat ^^

6:45 PM

I need setcookie not getcookie

11

A: Set cookie and get cookie with JavaScript

I'm sure this question should have a more general answer with some reusable code that works with cookies as key-value pairs. This snippet is taken from MDN and probably is trustable. This is UTF-safe object for work with cookies: var docCookies = { getItem: function (sKey) { return decode...

@DJMcMayhem Looks good to me.

> probably is trustable

@TuxCopter GPL'd though

this gave me............. renewed assurances about it's reliability :P

@KritixiLithos Not accessible from server

@KritixiLithos the point is we need access from server :P

But you can get cookies from server?

Yes, but not localStorage

localStorage !== cookies

6:49 PM

oh poop then

Cookies are sent with each HTTP(S) request.

cookies taste better than a local storage anyway

I thought that localStorage was the new cookies for some reason

We need to introduce tinCanStorage pls

localStorage is a map of big cookies stored client-side basically

6:50 PM

thats undersattement

Btw the flash is barely noticeable.

.____.

?

> Error during decoding Arcyóu

@Downgoat How this would be different from localStorage?

6:51 PM

it would be tastier

and better

But only goats eat tin cans

It would also bring more diversity into web devopment as goats would eneter the field

But it knows now that I prefer Dark over Light

6:52 PM

@TuxCopter im sorry is there problem?

why do I have so much time on my hands

In any case, it would still be better than the current state, since it just displays unknown now.

oh crap

i did a stupid >_>

question: what is SBCS?

Single byte character set.

FYI, @Downgoat make the "Run" button fixed so that it will always be there and not disappear on scroll

7:00 PM

What font is used on GH?

> ion GH

@KritixiLithos ok working on that ATM

51 mins ago, by Dennis

Fyi, you're violating Twitter's brand guidelines.

@TuxCopter system fonts

You can't use Open Sans to display @Try_it_online next to the Twitter logo. It has to be Helvetica Neue Pro, 75 Bold.

huh, domain transfers are less painful than I thought.

I wonder if something special will happen when it drops below 1,000,000 seconds. Or at any point other than 1 second.

7:17 PM

plz halp ;_;

click anywhere and pray

;_;

It don't work with (width*height-discovered_cases+number_mines)/(width*height-discovered_cases) chance

@Dennis i will change if i get notice because tbh its extra load time and all for another font

@TuxCopter k i solved it

thx anyway

El'endia Starman

7:21 PM

@betseg In the middle, where you have 3 1 1 1 going down the side, you can click the one directly next to the middle 1 safely. If there was a mine there, the first 1 would have to be a 2.

@betseg throw tin can at keyboard and hope for best

@Downgoat and what if he don't have a tin can?

@El'endiaStarman i clicked next to the 2 on middle right side vertical thing

user image

shit

rip betseg

accidently put 5 flags around 4

user image

is this possible?

7:26 PM

Minesweeper is great for codegolf challenges

^^yep

@DJMcMayhem change the 2 at lower left corner to a 3, add a mine at lower left corner, and its impossible

test case 4 you

Cool, thanks

do we have minesweeper KotH

~~How would it work?~~ nvm singleplayer koth >_>

@Downgoat codegolf.stackexchange.com/questions/102044/… codegolf

7:29 PM

@Downgoat Just turn it into an image.

then it won't be scaleable into larger size

will look bad on hidpi

El'endia Starman

Get an SVG of it somehow?

hm i guess

will do then

is there nay language on TIO where "..." should not be highlighted as string?

V

And brainflak for that matter

ah true

El'endia Starman

7:33 PM

Minkolang, ><>, and Befunge also.

A cool one man band

El'endia Starman

You're not guaranteed that strings are horizontal in any of those language.

user image

El'endia Starman

@Downgoat Make sure you take escaping into account. "\"" for example.

Querstion: is position of run button better or worse than before?

7:35 PM

Oh no, please don't waste vertical space.

hm :/ question: is there any rule that prevents me from doing: Polygot (bash, dash, mash, sh, bsh, csh, dsh) etc.

why no monospace ;_; i.stack.imgur.com/UTzT2.png

Either in the sidebar or in the same container as the text fields (either above or below them)

wait what

@Downgoat What's a nay language?

7:37 PM

@mınxomaτ I was thinking of adding sidebar on right which has run button, and input fields, and also shows byte count. That way entire center can be code

@Dennis >_> crap i mean any

@Dennis any, probably/ninja'd

@Downgoat That's fine, too.

@Downgoat Add Jelly to the list.

probably wouldn't work on mobile tho :(

El'endia Starman

@Dennis I was about to object that Jelly doesn't use standard quotes, but then I realized that you could put standard quotes in Jelly strings, and those shouldn't be highlighted.

7:39 PM

user image

@DJMcMayhem question: so are ()[]{}<> only valid chars in Brain flak program and all other are comment?

Generally speaking, yes

But @\a\a are debug flags

hm :/

should those highlighted?

Probably

A: Tips for Golfing in Brain-Flak

Use Debug flags You might not know it because we haven't written it anywhere but Brain-Flak has debug flags and they are really useful. They can be placed anywhere in the code and will run when the command line flag -d is present. Here is a quick rundown of the debug flags. Most flags come in...

Lines starting with # are real comments, so those should ignore brackets and debug flags too

hm :/ ok

7:43 PM

If anyone has time, please give this challenge a quick check to make sure I haven't left any holes in the spec

@DJMcMayhem is does (\n) still evaluate to 1 where \n is newline

Uhhhhhhhhhh... Yes? I'm not positive though

ok better question: should it?

Yes.

ok thats harder to syntax highlight so i'm just gonna skip it

7:45 PM

nevermind I can't read

ok this seems hard

@El'endiaStarman Also, " and ' are quicks and do something entirely unrelated.
