let n be the number on the tape

move your pointer n to the right hand side.

Detriplicate a String code-golfstringcounting A lot of languages have built-in ways to get rid of duplicates, or "deduplicate" or "uniquify" a list or string. A less common task, which also requires slightly different approaches when implementing it manually, is to "detriplicate" a string. That...

Then what do you mean, "right side"?

@Mego let's say tape[0] = 100

Oh wait nvm

I got it

then write a snippet

Where n is the value under the pointer

and you assume that all other values are zero

Oh wait is changing the tape values not allowed?

@Mego nice

@Ronronner Hello :D

@Mego could you do that as a bonus?

Joining the room of ridiculousness?

Anonymous

@LeakyNun It would be much more complicated

@Mego you just have to copy the number every time you move a space rightwards

9:35 AM

@LeakyNun That's not what he's already doing?

@MᴀʀsUʟᴛᴏʀ no, he decreases the number by 1 every time

the bonus challenge is to make the pointer at the nth cell while making that cell has a value of n

@LeakyNun oh

I love how active this room is.

If I should specialise in 1 language, Is it better Go or JS?

never programmed in go

but i think js

Ok

10:08 AM

@Sp3000 I use programming for code golf, pentesting and script.

@Ronronner For code golf? Learn Jelly/Mathematica

And for pentesting/script?

Well I guess if you're pentesting then you'd definitely want to know JS, but I don't know whether JS would be suitable for bigger general projects

@MᴀʀsUʟᴛᴏʀ mathematica is paid

@TùxCräftîñg oh yeah i forgot

10:10 AM

As a rule of thumb, I'm of the opinion that you'll probably want to at least dabble in several languages (not immediately, but maybe over time) just to get a feel for different languages

^

But out of Go and JS, probably JS first if you're pentesting yeah (though it also does depend on what pentesting you're doing too)

@Sp3000 Ok

I will improve my JS so

why is irc so weird

Learn many languages, and learn them well, so you will know which to use when you are faced with the choice.

yes?

blet is a no-op

in reality any thing that is not a command is a no-op

what exactly counts as a command, when it comes to skipping?

@DestructibleWatermelon a baa command is matched by ba{2,}, a bleet by ble{2,}t, and any other thing is counted as a noop

TIL gaot++ wrap backward

so, I'm not familiar with the commands, but

esolangs.org/wiki/Gaot%2B%2B

if i wrote, push 0, skip if not 0, beep (nop), some command

would "some command" be skipped?

10:46 AM

@DestructibleWatermelon no, a no-op is skipped

ok then, thank you

also who suggested compressed gaot?

@DestructibleWatermelon LeakyNun

it defeats the entire point, though

put a conditional skip in a loop is insanely hard ;_;

bleeeeeeeeeeeet bleeeet n Read
bleeeeeeeeeeeeet bleeeet n Duplicate
bleeeeeeet Skip if NZ
    baa baa bleeet baa baa bleeeeet bleeeet n Terminate
bleeeeeeeeeet bleeeet n Write
bleeeeeet Reverse the IP

i give up

freenode is broken for me :(

10:51 AM

and since the only way to push 0 is baa baa bleeet (1 - 1), this make bidirectional 0 near impossible :/

bidirectional?

@MᴀʀsUʟᴛᴏʀ the only looping construct is to reverse the direction of the IP

so bleeeeeet is a inifinite loop

why is 1 -1 not bidirectional

with what I've got in my Stackly extension

this is a truth machine: (wait a moment)

?<
*

a challenge it might actually win :)

@MᴀʀsUʟᴛᴏʀ baa baa bleeet is 1 - 1, but since in the other way the stack is empty when bleeet is called, i must do baa baa bleeet baa baa

10:57 AM

Explanation: ? makes the pointer move down if inputted bit is 1, else up. * makes the program restart while outputting latest move

Gaot++ is insanely hard >_>

i haven't found a hello world yet

I'll make a cat program after I make some more of the spec

@DestructibleWatermelon congratulations for a truth machine builtin ._.

it isn't a builtin

command

10:58 AM

nor a command

1<
*

ah i got it * is a star

that program infinitely prints one

seriously the only utility i find to this is a truth-machine >_>

well, when I add more commands it will be a large part of TC, man

i dont think Gaot++ is TC

11:00 AM

there are two restart commands: # *

because conditional loops are impossible

# is silent, * prints

@DestructibleWatermelon Then how do you do looping i/o?

well, when i update the spec, it will have a cat program

which will be slightly longer than the truth machine

ok, this is the cat program:

?<
1@
*

now do it in gaot++ lol

11:04 AM

@ works like this, it removes the used input, and next time input is required, it uses the ones after the used input (only useful when looping)

or it uses new input for the next iteration

shorter cat:

?<
*@

at least the infinite loop is simple: bleeeeeet

anyway, I still like 4 byte truth machine in a stackylogic variant

possibly less, depending on if i decide to do binary programs

@everyone what would be the advantages/disadvantages of a html/css/js OS

besides the JS

hey guys, I changed the way the starting position of the pointer works

?
*

one of the shortest truth machines

also a one byte quine:

or

nested loops have to be simulated, by the way

If that's possible

I think I'm creating a stackylogic golfing lang O.o

@Downgoat ARE YOU THERE

@Downgoat chevon chevon chevon

yum yum

I think I will call it Eseljic (Stacky Logic)

Eseljik actually

J, I, and K are close together ¯_(ツ)_/¯

I'll probably make a github thing soon.

@DestructibleWatermelon you have a gh account?

no, that's the first step though

Also I need a cool logo/mascot for my language

@DestructibleWatermelon many esolangs dont have a logo

my esolang is different <( ˚^˚)>

11:40 AM

so ¯\_(ツ)_/¯

How to get an interpreter for an esolang:

step one: make the spec

step two: got to ppcg

step three: Post spec with the tag code golf

and you get the most inefficient interpreter

well, noone would do a fastest code challenge, now would they ;)

12:25 PM

is there any way i can ensure two seperate servers that are supposed to be in a cluster actually send the correct data?

@zʏᴀʙiɴ101 what about dynamically generated data

Oh, right. o_o

Fun fact: In Mathematica, 2 01 6!! == 96

@LegionMammal978 wat

@MᴀʀsUʟᴛᴏʀ The expression was brute-forced, it calculates two times the double factorial of 6

For something crazier:

@LegionMammal978 what does the 01 do

12:32 PM

2#-01&@6 == 11

@LegionMammal978 double factorial?

@MᴀʀsUʟᴛᴏʀ The spaces are implicit multiplication, so it multiplies by 1 (doing nothing)

Double factorial

In mathematics, the product of all the integers from 1 up to some non-negative integer n that have the same parity as n is called the double factorial or semifactorial of n and is denoted by n!!. That is, n ! ! = ∏ k = 0 m ( n − 2 k ) = n ( n − 2 ) ( n − 4 ) ⋯ ...

@LegionMammal978 not that hard to figure out, i saw the challenge when it was posted

@LegionMammal978 i mean that specific one won't work for next year

(That is, once I finish de-mutilating it (I needed the API code, okay?))

Eseljik has exactly two quines, each 1 byte

it's such a clean (not sure if this word is appropriate) expression (the only symbols are two exclamation marks, at the end as well)

@MᴀʀsUʟᴛᴏʀ That's because space and ! are the first two printable ASCII characters, so they're favored over higher-valued characters

help, idk if there's anywhere better to ask, but:

how do i prevent servers you don't control, but hosting your website, from sending the wrong dynamically-generated data

12:47 PM

@DestructibleWatermelon code?

How is the data wrong?

@MᴀʀsUʟᴛᴏʀ Uhh, contact the server owners, perhaps?

This is more theoretical

@TùxCräftîñg 1 and 0

ah >_>

12:48 PM

say you wanted a distributed cluster, could you prevent servers hosted by others from sending the wrong data?

13 bytes for division

sesos.tryitonline.net/…

(does not halt if non-divisible)

Eseljik still has the <, however, some programs do better without it.

@MᴀʀsUʟᴛᴏʀ The main issue is that you do not control these servers, right? I don't see how there's anything you can do other than 1) trust the owners, 2) contact them, or 3) take your business elsewhere.

@feersum I've been trying to do the Mario challenge in Snails and I'm failing... it's cases like snails.tryitonline.net/#code=&input=ICBFClMgPQo9ID0KPT09 that I'm not sure how to deal with, due to the slime.

@HelkaHomba the . makes me cringe (unless you you wanted to take the dot/matrix product of Mathematica and the witty remark?)

the dot product of mathematica and a witty remark ಠ_ಠ

It is easy to prove that 1 and 0 are the only quines, because: only 1 and 0 can be output and only 1 bit can be output without non-1 0 characters, unless you also count [null] as a quine

Helka Homba

@MartinEnder What would the syntax be?

@HelkaHomba I think there would just be no Mathematica.
