The Nineteenth Byte

Sorry, broken internet on computer disallows me to check the Nineteenth Byte on the computer. So I can't add your name to the leadboard.

ArtOfCode

@zyabin101 eh? How's that work, if you're here?

Surely if you're here, you can check TNB

@Fatalize Please wait until I update the leadboard.

@zyabin101 pl Hello, _!

@LeakyNun The dictionary comes with Jelly (at least I thought)

Leaky Nun

5:16 PM

yes but I can't find the index

Dennis

>>> import dictionary
>>> dictionary.short.index("hello")
7704

quartata

Yeah, that

I'm not sure why you need the index though unless you're compressing by hand

orlp

@Dennis why a short dictionary?

Dennis

There are two dictionaries: one for short and one for long words. Encoding long words requires more bytes.

orlp

yes, why split them?

Downgoat

5:19 PM

@zyabin101 :D \o/

Leaky Nun

@Dennis And then convert to base 250?

@LeakyNun Not quite that easy. You should really use Lynn's script.

Leaky Nun

alright

orlp

@Dennis again, why split the dictionary into two?

I assume the dictionary is sorted by most common word first?

@Sherlock9 You can look at the commit log on github to see what features were implemented

zyabin101

@orlp Alphabetically.

orlp

@zyabin101 that seems like throwing away information

zyabin101

@Mego Why did he need this?

Dennis

@orlp No, they're sorted alphabetically. I'm planning to revamp compression.

orlp

@Dennis even then

zyabin101

5:21 PM

@Dennis ninja'd

orlp

why two dictionaries?

sort on length first

Dennis

@orlp That only helps for a single word, not a string or words.

Downgoat

@zyabin101 created a pull req for the blog

orlp

@Dennis you have dabbled in arithmetic coding before, haven't you?

Dennis

Yeah, with arithmetic encoding, that wouldn't be a problem.

orlp

5:24 PM

here's a proposed scheme for encoding a word

Dennis

This was only a first draft. I planned to revisit it later.

zyabin101

@Downgoat Merged.

orlp

store the dictionary of words sorted by how common they are

Downgoat

\o/

Dennis

@orlp Easier said than done. How do I get that information?

orlp

5:25 PM

so the becomes 0, and most becomes 99

Dennis

All lists I can find online are either horribly outdated or completely unrelated to words you could find in a code golf competition.

Oooooh, more people fork Jekyll Now. The blog now has 9111 "forks" that are actually received by the official Jekyll Now repo.

quartata

zyabin101

5:26 PM

@quartata It's ninja'd >_>

orlp

@Dennis anyway, that's just the first step

now how to encode a word

let's say a word has index 99

Fatalize

The 42th most common word is "free". Coincidence?

zyabin101

@Downgoat Thanks to your contributions, you now have write access to zyabinVI/blog!

orlp

that's 0b1100011

Adnan

@Fatalize yes

Downgoat

5:27 PM

@zyabin101 \o/

orlp

that's 7 bits long

so you first encode the length of the word in bits in unary

11111110

then you encode the actual bits themselves

so end result is 111111101100011

Fatalize

The index for "contact"... coincidence? ( ͡° ͜ʖ ͡° )

orlp

now, that might seem bigger than necessary

but that's before arithmetic encoding

Fatalize

9959 - telecharger

orlp

when encoding the unary, you put the probability of the first bit being 1 at 100% (because a word will always require at least 1 bit)

Fatalize

5:29 PM

wtf that's not even English

orlp

the second bit at 50%

the third bit at 25%, fourth 12.5%, etc...

Adnan

@Fatalize ( ͡° ͜ʖ ͡° )

ce n'est pas anglais

orlp

if english is more skewed towards more common words, you can alter this distribution

Fatalize

9995 - Swaziland
10000 - Poison

quartata

@Fatalize Probably a pretty common French word on the Internet though

Fatalize

5:30 PM

how is that possible, muricans don't know about swaziland

quartata

Although I thought these were supposed to be from books...

orlp

that's with binary arithmetic coding

Fatalize

@quartata well yeah, it says US-english words but...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@CᴏɴᴏʀO'Bʀɪᴇɴ HAI

orlp

if you want to use full arithmetic coding, you just use the histogram from the words

Fatalize

5:31 PM

9981 - ctrl

"words"

very loose definition

orlp

@Dennis norvig.com/ngrams/count_1w.txt

Fatalize

658 - california
659 - porn
660 - share

Downgoat

@Fatalize ._.

Fatalize

206 - p

very reliable list of words :p

Dennis

@orlp Good ideas. I'll also have to think about how I can encode strings that aren't in the dictionary.

quartata

5:38 PM

Also capitalization and punctuation

orlp

@Dennis by putting it in the dictionary :P

quartata

Maybe just an extra bit for "first letter capitalized"

orlp

@quartata now the beauty of arithmetic coding is that you can assign a fractional bit to this :)

quartata

Ah yes, true

orlp

if the first letter of a word has a 10% chance of being capitalized, you only take -log(0.9, 2)*0.9 + -log(0.1, 2)*0.1 = 0.47 bits on average

quartata

5:42 PM

Hmm, I wonder what good weights for punctuation should be. ,. should probably have higher probabilities than ?!

Ooh, I forgot semicolons. That's tricky because while those don't come up much in sentences they're common in code (not Jelly code obviously)... Still, probably won't come up that much

@zyabin101 ??

zyabin101

@Downgoat let for constants, var for variables.

Downgoat

not const for constants?

zyabin101

@Downgoat Okay, const for constants.

let for global variables, var for local variables.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Downgoat

too many things

Cᴏɴᴏʀ O'Bʀɪᴇɴ

6:02 PM

if anything, let should be local. "Let x = 5, and you'll see that x + 5 is 10." x is further irrelevant.

orlp

@Downgoat no

nothing for constants

mut for mutable variables

quartata
