The Nineteenth Byte

MD XF

7:00 PM

@Okx You're asking a bunch of code golfers about sanity. You might want to turn somewhere else. :P

Okx

but we are sane

only crazy people format code with spaces and whatnot

DJMcMayhem

Just took 8 bytes off of a 6-month old answer I've mine. Feels good man.

MD XF

@DJMcMayhem pls link

DJMcMayhem

@MDXF OK

MD XF

Meh already voted it

Also I don't see the 8 bytes off

DJMcMayhem

7:07 PM

It was in two chunks

MD XF

Ah yes now I see

DJMcMayhem

It was 149 earlier today, then I went down 4 by drastically changing the approach, then down another 4 by going back to the original approach

MD XF

Not bad

Downgoat

@LeakyNun oh, lol map callback has 2 args value, index, so it's really adding value + index :P basically you end up with (+)(value, index, 1) since you've right-bonded

I reccomend n->n.map((+:1))

MD XF

Similar to this, I changed the approach at least six times while trying to get it to spec

I think the first byte is leftover from my initial approach, but I have no idea why it would be there as I never had any use for a loop ಠ_ಠ no way to golf it off anyway so might as well leave it I guess

Leaky Nun

7:10 PM

@Downgoat is it a bug?

Downgoat

not really, it's just a quirk

You could say it's been 'fixed' with (+:1) because that is correct way to right-bond ops

TIO cheddar doesn't support it yet tho :(

DJMcMayhem

Hahahahahaha, Oh wow, I borked it bad: Try it online!

Downgoat

@DJMcMayhem :| and I thought Jelly was hard to read :P

DJMcMayhem

It is.

Leaky Nun

@Dennis Why does TIO use SBCS for C (gcc)?

Okx

7:16 PM

probably because of bork

user165474

Okay so my language is ready for me to start adding on a ton of functionality (the tokenizer and interpreter seem to be fixed after I broke it about 5 times). What does everyone suggest for the focus of the language? e.g. string mod, list mod, 2d string mod (ASCII art), math, general (essentially rewriting Jelly except worse), etc. Destructible suggested to do lists and I'm thinking of doing mostly math and lists; any other suggestions?

MD XF

@HyperNeutrino Math and lists sounds cool

user165474

yay :)

user165474

Also, pushing again

Poke

@Okx That may or not be true... but we also make more money

totallyhuman

7:21 PM

i started writing a language and then i realized i'm not creative and the idea's already been done

betseg

rip

Okx

@Poke money is crazy

a piece of paper is equal to a chocolate bar

this is over powered

Poke

all transactions are just bartering when you think about it

totallyhuman

there needs to be some ridiculous, extremely hard language idea that hasn't been done yet...

user165474

@totallyhuman How about make a language where the memory is stored on the surface of a 20-sided Rubik's-Icosahedron? Similar to Cubically (?) but even MORE confusing :D

MD XF

7:24 PM

cubically fulfills that @totallyhuman

@HyperNeutrino hehe status-wip

I'm currently working on making Cubically extendable so that the memory can be a 5x5 >:D

totallyhuman

hmm

memory on a grid?

MD XF

No, memory on a freaking Rubik's Cube

user165474

(The surface of it)

totallyhuman

no i was asking if it was done before lol

MD XF

The only memory operations twist the cube

Well IDK if grid memory has been done before, but cube memory hasn't

user165474

7:26 PM

@totallyhuman I would not be surprised

totallyhuman

side note: what is with the chat.SE notification sound o0

MD XF

@totallyhuman this one?

@totallyhuman :P

user165474

Wait is something wrong with it?

totallyhuman

:P

it just sounds weird to me :P

user165474

@HyperNeutrino Has it changed?

MD XF

7:26 PM

Naw it's just weird @totallyhuman

Yep

user165474

No it's the same.

Poke

it's really jarring

MD XF

@HyperNeutrino and that is why I don't use caret-reply

@Poke Jarring, you say?

totallyhuman

@MDXF troll :P

Poke

i have sounds muted at the moment

:P

MD XF

7:27 PM

@totallyhuman Heh I'm deaf :P

user165474

@MDXF I intentionally used it... I wanted to hear the sound. :P

totallyhuman

@HyperNeutrino here have it

MD XF

@HyperNeutrino This sound?

user165474

ಠ_ಠ I already got it >.< and besides, I muted my system again after hearing it...

MD XF

@HyperNeutrino or this one? :P

user165474

@MDXF Neither.

user165474

@totallyhuman your computer explodes

MD XF

@DJMcMayhem Me too, all the Triangular bugs took less than four minutes to fix

user165474

7:29 PM

I tested it. My computer just blew up.

user165474

@MDXF All 50-something of them!?!?!?

MD XF

There's one intentional bug that no one knows about

No that was Cubically @HyperNeutrino

and those bugs took like an hour each lol

user165474

oh rip

totallyhuman

hmm what about a 3d lang

o0 how would you do that

MD XF

I don't think that's ever been done

There are hundreds of scholarly articles about it

totallyhuman

7:30 PM

code that transcends your computer

user165474

@totallyhuman carefully

MD XF

but seeing as how a file can't really store three dimensions per se, I have no idea how that'd be done

user165474

@MDXF Then make them able to do that :D

Apr 2 at 15:51, by Kritixi Lithos

Here's an idea for an esolang that I just thought up:

I had an idea for a 4d language

MD XF

Oh holy sh*t I think there's a 3d version of befunge

totallyhuman

No manual entry for me?

user165474

@MDXF

MD XF

@HyperNeutrino Requires an older version of man

user165474

oh

MD XF

It used to only support one-two arguments lol

user165474

7:31 PM

lol

user165474

sudo apt-get install sl

totallyhuman

@KritixiLithos wat

MD XF

alias ls=sl >:D

user165474

It's used to punish people who accidentally type sl instead of ls.

totallyhuman

yes but it do sl most of the time just for fun

user165474

7:33 PM

alias a=b, b=a

totallyhuman

it's a nice locomotive

MD XF

@HyperNeutrino #define if while and #define for if, watch them wonder why a for loop can't have a semicolon... and watch them not realize the while >:D

user165474

NOTE: DO NOT ACTUALLY DO ANY OF THE ALIASES BELOW

Okx

alias ls=rm -rf /

MD XF

@Okx heh

Okx

7:34 PM

@MDXF i improved your alias :D

Kritixi Lithos

@totallyhuman so yeah, the fourth dimension is time, so you can access information from the past (and maybe the future, but I don't know how this will be implemented)

totallyhuman

@HyperNeutrino o0 i think my brain has auto-correct

MD XF

alias wget=ping

or alias ping=wget

user165474

alias rm=rm -rf / then watch as people try to delete something and accidentally delete everything

Kritixi Lithos

@Okx alias rm="echo \"You can't use rm\" #"

user165474

7:34 PM

alias cd='rm -r'

MD XF

Heh this (conversation) is awesome

Okx

alias alias=alias alias alias

totallyhuman

alias alias="alias #"

user165474

@Okx 0/10 you need quotes

Kritixi Lithos

that what I actually have in my bashrc

MD XF

7:35 PM

alias alias=unalias and unalias unalias

Poke

@HyperNeutrino you forgot "--no-preserve-root"

user165474

@Poke close enough

Okx

@HyperNeutrino i break what i want thank you very much

DJMcMayhem

While we're on the topic of funny aliases, I have this in my .bashrc:

user165474

MD XF

7:36 PM

My favorite for MinGW systems: alias ls='cmd.exe /C DIR'

DJMcMayhem

alias :q="echo 'This is not vim ye daft idiot!' && sleep 2 && exit"

totallyhuman

heh

MD XF

@DJMcMayhem HAHA

user165474

@DJMcMayhem HA when you know you vim too much

MD XF

That is now an alias in my bashrc

Jim

7:37 PM

zsh > bash

user165474

fish > zsh

user165474

MD XF

alias bash=zsh

Okx

betseg

MD XF

7:38 PM

@betseg hehe

Oh heh how about this: alias gcc=rm

Poke

as a fun prank, add this to a co-worker's .bashrc: echo "sleep 1">>.bashrc

DJMcMayhem

On a more serious note, I have a mkcd command, and it's super useful

user165474

@betseg 0/10 plagarism that's just my message ungolfed

MD XF

I have an xkcd command, it prints Black Hat in ASCII art (it now also pings XKCD)

user165474

@DJMcMayhem mkcd $i -> mkdir $i && cd $i?

DJMcMayhem

7:38 PM

Yeah

betseg

@HyperNeutrino o shit i didnt see ur message sorry D:

Okx

@MDXF but it doesn't actually ping xkcd

MD XF

@Okx just updated it lol

Okx

wow ur so fast at making commands are you a robot

MD XF

I have a script

Poke

7:39 PM

it makes shells take progressively longer to open

MD XF

modrc <alias name>=<new alias>

user165474

@betseg lol that's fine mine was confusing anyway

betseg

i have this: alias breakmysystem='pacaur -Syuu --noconfirm --devel --noedit'

user165474

ooo I wonder if I will be able to eventually surpass betseg in rep (not plotting anything)

MD XF

It automatically deletes the line where <alias name> is aliased and appends alias <alias name>='<alias>'

Jim

7:40 PM

@DJMcMayhem Likewise I have a cdtemp and rmtemp

MD XF

@Jim alias rmtemp='rm /tmp'?

DJMcMayhem

I would hope not

Jim

copy files to a newly created dir, rmtemp delete it and return to previous path

MD XF

Ah

user165474

mvtemp: temporarily moves your files to the specified location. They will be moved back at some random time in the future.

MD XF

7:41 PM

Oh my favorite alias is alias man='echo No manual entry for $1'

user165474

Stop forgetting close quotes ಠ_ಠ

DJMcMayhem

@MDXF .... Oh it hurts so bad

MD XF

You mean like 'this?

Jim

Too much golfing with esoteric languages

user165474

(this is worse

MD XF

7:42 PM

@DJMcMayhem heh I have a script on a USB called trollscript.sh and I stick the USB in, run it, and it'll screw many things up

rm aliases to rm -rf, apt-get aliases to apt-get remove $1 &&

vim aliases to ed >:D

@Jim ...how was that related to the conversation at hand

Jim

Do you actually use it?

user165474

alias alias=echo

MD XF

@HyperNeutrino accurate

@HyperNeutrino Hehehe

alias cat='cat >'

cat big-source-file.c :o why is it empty

Jim

@MDXF The reason why you keep forgetting closing quotes is probably because of "Too much golfing with esoteric languages"

MD XF

@Jim Ohh okay :P probably true

Huh, I just realized... I have never golfed in an esolang that was not my own

Jim

7:48 PM

And those are?

MD XF

shortC, Decimal, Triangular, Cubically

memescript, rk (not really an esolang), many trivial Brainf*ck derivatives

and whatever else is on my esolangs page

Jim

That's quite a few. I particularly like Cubically. Seems awful to use

MD XF

That's it's entire purpose haha (also there were no existing languages based off cubical memory when I wrote it two days ago)

The Hello World took 35 minutes to write, IIRC

muddyfish

8:04 PM

I now have permission to write that KOTH :D

Dennis

@LeakyNun Given that TIO doesn't support different encodings yet, these are pretty much arbitrary choices. X bytes (Y) means that the code is X bytes long if it can be encoded in Y, not more and not less.

MD XF

Cool! You also now have permission to write the Cubically quine hint hint :D

muddyfish

Heh. I'm not sure how I'd start writing that or anything in the language

MD XF

I think I've answered two or three things in Cubically, one being the Hello World lol

I think we need to not be named "Programming Puzzles and Code Golf", since we don't actually allow regular Programming Puzzles most of the time. "Code Golf and Programming Contests" is more descriptive of what's actually done here, and would help to reduce the amount of bad challenges.

@ATaco feature-request: Make that chat preview have a "hide" button or hotkey, and make the text wrap when it reaches the starboard instead of the edge of the page, because currently it extends behind the starboard and also it blocks messages underneath.

Jarko Dubbeldam

What do you guys think? Is this sandbox challenge (https://codegolf.meta.stackexchange.com/a/12893/59530) sufficiently different from this existing one (https://codegolf.stackexchange.com/questions/38173/play-the-chaos-game)?

Mine adds actually showing the animation of the game in progress, but I am not sure if that is different enough.

Phoenix

Haven't read it yet, but if it's just inserting time.sleep(1) at each iteration, it's not different.

Jarko Dubbeldam

I guess it depends from language to language how much of a difference it makes to plot the steps instead of the final result

MD XF

Speaking of sleep, has anyone noticed how the C implementation of sleep is like 50 lines of code and makes low-level Unix function calls, while this works fine:

void sleep(int seconds)
{
    for (int t = time(0) + seconds; time(0) < t;);
}

Phoenix

8:22 PM

Why is it returning an int

MD XF

Because it's golfier than void, i.e. I'm lazy

I mean, yeah, my implementation isn't thread-safe, but the C standard library isn't built to be thread-safe

IDK why they decided to have some of the functions be extra-complex for thread compatibility while completely not bothering with others

isaacg

@LeakyNun Do you have a test case? I could try and investigate some, but I can't seem to replicate.

Downgoat

@MDXF this blocks the whole thread though no?

MD XF

I mean, yeah, my implementation isn't thread-safe, but the C standard library isn't built to be thread-safe

Downgoat

not about thread safety just efficiency

MD XF

8:34 PM

Oh. yes AFAIK it blocks the whole thread

Downgoat

I'm 77% sure that C stdlib's sleep function is not a busy-wait

MD XF

Yeah it's not, it uses alarm

user165474

Downgoat

MD XF

Where did the number 77 come from?

Downgoat

8:36 PM

it's my estimated confidence

there are an infinite about of numbers you can use and people only use 99% (or some variation), 100%, 0%, and 50%

MD XF

s/they/there but yeah I agree

user165474

> 24.35735%

Downgoat

It's not too specific. just do a scale of 1-5, multiply by 20, then take a scale of 1-5 again and keep proportionately scaling

@BradC yes unless SQL can take an encoding in which they are one byte
