The Nineteenth Byte

Chris Jester-Young

00:00

@Winny Are you planning to attend RacketCon? I don't know if I can make it, but I hope to!

Winny

@ChrisJester-Young I've never been to a lang/floss/cs related convention. Maybe some year! I'd love to go to Wikipedia's yearly convention or PyCon, RacketCon sounds fun too

Chris Jester-Young

@Winny Cool. If you do attend one, it'll be cool to meet up. :-)

Winny

@ChrisJester-Young It's always fun to meet people that write code -- I met this guy at a local makerspace who is partly responsible for uggle (sp?), some bytecode VM for business rules used by FedEx

Sp3000

We should probably figure out if #lang racket counts to the byte count :P

Winny

Should I create a question on meta?

Chris Jester-Young

00:08

@Winny Nice! Small world, etc.

Winny

oddly, yes

Chris Jester-Young

@Sp3000 Yes, I would consider it to count.

Winny

oooo, I have been cheating! :P

Sp3000

Question might be good. I've been including it but Winny hasn't, hence confused

Chris Jester-Young

@Sp3000 Cool, let's do a poll. :-)

Maltysen

00:11

@phase 256

always

Sp3000

Would Winny be okay with writing the question? I don't know enough about Racket to even know why that line's there

Winny

I'm pretty new to Racket myself, but I could write it

Installed it like 3 weeks ago

Sp3000

Ahaha k, thanks :)

Chris Jester-Young

I could write it, if nobody else wants to. *shrug*

But if Winny wants to do it, of course I wouldn't object. :-)

Sp3000

(I only learnt about my Racket via my programming paradigms lectures - we never had to use it in the course though)

Chris Jester-Young

00:13

@Sp3000 The #lang line is there to specify the language in use. Racket has support for many languages, like racket, racket/base, r5rs, typed/racket, htdp/isl+, etc.

Sp3000

Oh? Interesting...

Chris Jester-Young

I also want to implement a golfscript language so you could use #lang golfscript and run it in Racket.

Sp3000

And add 17 bytes to the byte count very time before you even start coding :P

Chris Jester-Young

Well, you'd run it in Racket because the reference interpreter is too slow. :-P

It's not like I plan to make Racket-specific functionality for it.

phase

@Maltysen 256 to 128?

Maltysen

00:18

I'm confused, what do you mean by what base I use

I store all my string in base 256

when encoding

phase

@Sp3000 I feel it's like a shebang. And those aren't counted in Shell scripts.

@Maltysen When decoding, what base to you go from and to?

Sp3000

@phase Usually with Kolmog you use a number of different bases, in case you get unlucky and hit a character that needs escaping

Maltysen

256 -> depends

26, 128

<10

really depends on the challenge

Winny

BTW how do I reference a question in there so that it shows a little badge?

in here.

Maltysen

@Winny automagically hapens

Winny

00:22

oh it does. Here's the question then: meta.codegolf.stackexchange.com/questions/5635/…

phase

@Maltysen Wouldn't that only return control characters?

Maltysen

@phase base encoding doesn't have to be to code points, its real purpose is to encode numbers that may or may not be interpreted as code points

26 is letters of alphabet, <10 index from small sring

like in the minecraft one

phase

@Maltysen 26 is letters of alphabet where is that designated?

Maltysen

nowhere, I do it myself: @LG

phase

you map it?

o-lang.herokuapp.com/link/…

Maltysen

00:28

i don't know O...

phase

Just the output. It converts the input to base 256, then back to 128, and prints the ASCII values of it.

And by all the code snippets I've pasted here, I assume someone knows O.

I can't find documentation on @ anywhere

Chris Jester-Young

@Winny You mean you want to onebox your question? Post the link on the line by itself.

Winny

@ChrisJester-Young Yeah that, thanks!

discussion racket

Chris Jester-Young

@phase Meta posts don't affect your rep.

Maltysen

@phase well the approach is to encode a list of numbers as base 256. Those numbers could be codepoints, letters of the alphabet, characters of some string, just base 10 numbers, whatever.

phase

@Maltysen I was thinking you could somehow compress source code, convert it, and eval it. That might make it smaller than the real code.

Maltysen

00:41

@phase certainly

but if compressing arbitrary strings is your goal, base conversion is probably not the best

bzip or such

phase

@Maltysen What is this bzip?

Maltysen

Bzip2

bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm. It only compresses single files and is not a file archiver. It is developed and maintained by Julian Seward. Seward made the first public release of bzip2, version 0.15, in July 1996. The compressor's stability and popularity grew over the next several years, and Seward released version 1.0 in late 2000. == Compression efficiency == bzip2 compresses most files more effectively than the older LZW (.Z) and Deflate (.zip and .gz) compression algorithms, but is considerably slower. LZMA is generally more...

Chris Jester-Young

@Maltysen These days, xz is a more common compression type. ;-)

@phase Unless your language expressly supports compression, you must include the decompression code in your byte count. ;-)

phase

@ChrisJester-Young expressly meaning I add an operator that does that thing?!?!?!?

or just make a language that "compiles" to Pyth which is really just compressed Pyth code.

Maltysen

@phase I thought that was what we were talking about

its has to run the pyth code...

phase

00:47

@Maltysen me too, just making sure

@Maltysen Shell script that calls the compiler to Pyth code then calls the Pyth compiler

Chris Jester-Young

I'm wondering if I should add that to the Standard Loopholes, basically stipulating that what's submitted must actually be source code.

Of course, that excludes object code and bytecode entries, which would be unfortunate.

Maltysen

@ChrisJester-Young I think we could say has to be manually written which was the case for machine code anyways.

Chris Jester-Young

@Maltysen Right, not auto-generated.

phase

But who would want to manually figure out base 256 strings?

Winny

BTW, use LZMA over XZ since LZMA doesn't have a large header like XZ does

(for golfing)

iirc.

➜  code  echo 'hello world!' | xz -c - | wc -c
72
➜  code  echo 'hello world!' | xz --format=lzma -c - | wc -c
36

wow, pretty big overhead

gzip is only 3 bytes shorter in that test

Maltysen

00:55

bzip?

I don't think it has headers

Winny

(it might also have something to do with how these cli tools compress streams as opposed to files of a known length and seekable content

Chris Jester-Young

@Maltysen Of course bzip2 has headers.

Winny

➜  code  echo 'hello world!' | gzip -c - | wc -c
33
➜  code  echo 'hello world!' | bzip2 -c - | wc -c
51

Maltysen

@ChrisJester-Young 4 bytes

Winny

has a large overhead, in this test, not sure why

too bad Racket only has gzip

Maltysen

00:57

ah 4 byte CRC

Winny

BTW just found out #!racket also works, @ChrisJester-Young

Chris Jester-Young

Yep.

Sp3000

Oh? Yay bytes

Winny

Or! Or! racket < sourcefile.rkt

kind of cheating imo, but it works

phase

@Winny How do you do multi-line code blocks?

Chris Jester-Young

01:03

@phase Prefix each line with 4 spaces.

phase

O v1.2 >> "phase is really cool"T.o"\n"oUo
???????Ù????
phase is really cool

Blows my mind.

I had it, then I didn't.

Winny

➜  code  cat g.rkt

  (displayln (string-append "Hello, " name "!")))

I want to make a web tool for my grandpa to use. Tatar is his first language (English is his third, and it shows), but he learned Tatar in the 1920s when the Arabic alphabet was used. Since the 40s a Cyrillic alphabet has been used, and a Latin alphabet emerged in the early 2000s. My grandpa can only read the Arabic alphabet, so I wanted to make a tool to translate between alphabets.

Hard to say. There are no real functions (just operators), so sine and sum fall in the same category. Most operators are also overloaded.

in most operators

Beta Decay

Bloody hell :O

Maltysen

@Optimizer That is not true. Only in some of them :)

Optimizer

even if I am exaggerating, its 4 level in many operators at the least

@Maltysen have you caught up to all the new things ? ;)

Maltysen

Most of them? If I knew what a fixed point operator was...

Beta Decay

Still crazy ;)

Dennis

The collections are hardcore. .t alone is 14 functions in one operator.

Beta Decay

It's isaacg who develops Pyth isn't it?

I get mixed up between isaacg and aditsu

Dennis

Yup.

isaacg created Pyth, aditsu CJam.

Beta Decay

Yeah. No wonder Pyth is so good at golfing

Maybe I should reconsider learning it

Maltysen

@BetaDecay we have an outdated tutorial that covers maybe a third of all operators, and none of the dot functions, if you're interested ;)

Beta Decay

@Maltysen The tutorial seemed to jump around a bit for me. How did you learn it?

Maltysen

19:28

@BetaDecay I was the one who wrote most of that tutorial actually, so for me it was a lot of looking at source code.

Winny

@BetaDecay pyth source, the debug mode, and other examples

most people will comment on your answers on how to improve them with equivalent expressions

Beta Decay

Thanks guys. Another summer project to do :)

Q: Chess floor problem from topcoder

I came across this chess floor redesign with smallest number of tile changes problem. Here is the link: http://community.topcoder.com/stat?c=problem_statement&pm=13917&rd=16512 I understood the problem but two of the samples that has been quoted there are misleading / doesn't have enough explana...

Q: Quit Whining; Start Quining

Quit Whining; Start Quining Goal: Write a function or program that, given an integer n, will output a program that is a quine with a period of n. Description of Output Program: The output program needs to be a program that, when run, ... will output a program... that will output a program... ...

code-golf quine

Chris Jester-Young

@NewMainPosts Catchy title. :-P

Dennis

Argh! A quine problem minutes after I hit the rep cap...

Chris Jester-Young

@Dennis Wait 3 hours, 13 minutes before you answer.

Dennis

I will. But chances are that somebody else will find my solution in that 3 hours...

Peter Taylor

Someone already linked to it in the comments.

Dennis

No, the solution I'm thinking of.

Quite similar to what I posted a few weeks ago, but not identical.

Peter Taylor

I'm not going to close-vote, because it would be binding, but I agree that it's at best borderline dupe.

Geobits

^ That seems to be the best argument against dupe-hammers I've seen.

Dennis

It's close, but it has a sane scoring algorithm and since the length of the produced quine is not important, there's a little room for tricks to reduce the generator's size.
