what sorts of compression can /prog/ program?
[spoiler] Infinite compression would be nice, but reasonably not expected..[spoiler]

hm, i need some stats now ^^ for -Micro_prog-
number of (common-ish) 2-letter words? 3-letter / etc..?
*looks at own posts* ... ah that'll never work ^^
...what about the number of unique ascii trigraphs on prog?

>>2
Is it really?

>>6
what about you jump in a lake full of aids ridden nigger dicks

>>1
The universe is compressed into itself and it's infinite.

>>7 probably, I wouldn't put it past a frog to upload some to this board

>>10
Surely this thread would've been deleted by the administrators by now if it was, they're generally quick about that specific thing.

So whats in the final zip?

>>12
Undetermined as of yet, no one besides the FBI is gonna care enough to give filehosting.com (what a shit choice) an email in order to download it and then unpack it, but considering the file is 440bytes it's bound to be something very heavily compressed. They're probably still waiting for it to finish decompressing.

>>9
inconmensurable, not infinite. there's nothing infinite. just because you can not measure it does not mean it's infinite. that's unscientific and ultimately destructive©

>>12
I didn't download it, but I'm guessing it's something like this:

>>14
There is something infinite, say for you to remember irrational numbers. So there, something infinite exists. Now, I suppose you'll say they are just virtual or something to that kind, which is when I'll say the universe is virtual too. Ergo following some thought from your side. Infinity exists.

>>15
It is possible to construct a zip file which expands in Peta Bytes. But it is beyond the possibilities most dwellers here have. I think most hardly understand what compression is.

>>17
I bet you understand the principle of holographic compression tracing a schwarzschild radius.

>>18

Holographic compression exists, but it is simply a technique using global information instead of local for compression.

The holographic principle says all the information in an 3 dimensional object can be compressed in it's two dimensional shell. It is related to black holes, you cannot compress them further.

The Schwarzschild radius is the radius, where the escape velocity is higher than the speed of light.

The principle of holographic compression tracing a Schwarzschild radius is bullshit. Or is the title of some obscure paper.

And I wish you good luck tracing a Schwarzschild radius, may you're information density be maximized.

>>19
The Schwarzschild radius is the radius, where the escape velocity is higher than the speed of light.
Does that mean that once you orbit that object, there is no way back?

>>20
once you land that object
self fux

>>19
Took you sometime, but surely it's not bs, you have 3 dimensional objects slipping into the tightest pocket you can find and what do you get if not the Schwarzschild radius. There you have it holographic (3d to 2d) compression tracing the schwarzchild radius since it's well, it is it.

>>21
self fix
self fix

>>20

Yes. If you go to a blackhole and put you arm through the Schwartzschild radius you will not be able to pull it back. You will not feel you arm any more.

>> 22

So, it is a little toy model to compress stuff, compressing your hard drives instead of the information on it. I think you could make a physical hashing algorithm out of it. The way back isn't easy.

>>22
Wouldn't it possible to flatten the 2 dimensional surface so it will have size 0 in the third dimension? That would be great for books in a library.

>>19
Does it not strike you odd that matter, energy, basic algebra and the speed of light just happens to be the deciding factor in compression limits?

>>26

I think it hints the fundamental unit is information. That would be very interesting.

>>27

That energy and information have more in common than we might think. We already knew that matter and energy is equivalent. Nowadays we getting some glimp of the relationship of energy and information.

Information is Complexity is Energy is Matter is Space is Time.
It's all a matter of parameters and how they parse, which is where the pure untyped lambda calculus comes in.

That which is below is like that which is above that which is above is like that which is below to do the miracles of one only thing.

Hey! I just compressed my entire touhou hentai collection down to the number 42. How do I decompress it back?

>>32, the same way you compressed, but reversing your actions.
-23

>>34
I don't remember how I did it.

>>33
<censored data>
Please don't post such obscenities! And your preference in porn is disgusting.

>>34

Sometimes this is not possible. Eg. If your compression function f is a map from n*m matrices to integers, it is not possible to compute the reverse map. The measure of the set of 1*1 matrices is the same as the measure of the set of integers. So multiple instances of the left space point to the right space. The function is not injective.

>>37
This might surprise you, but the set of all m*n matrices of integer values is a countable set, and can be mapped injectivly into the set of integers.

>>37
Amateur mathematician detected.  It is obvious that there is a bijection between the set of mxn integer matrices and (m*n)-tuples of integers.  Now there is another bijection between the set of (m*n)-tuples of integers and the set of integers.

Denote this bijection f.  Let v in the set of n-tuples.  Define the (i+nk)-th (where 0<=i<n) digit of f(v) to be the k-th digit of the i-th component of v.

what is a real number?

an equivalence class of rational Cauchy sequences

what is a real number?

a miserable little pile of cauchy sequences

>>39
Although, >>37 did say measure, instead of cardinality. But being able to or not being able to map one set into another injectively is related to cardinality, rather than measure.

>>40

There are other constructions too. The construction itself isn't that important, but the high level properties that are true about them. It's good to know that there is at least one low level construction so that logical paradoxes can be avoided when assuming their existence.

#!/bin/bash
#infinite compression
echo "enter file name"
read filename
echo "0" > $filename
echo "done"

>>43
Don't tease me like that bro. Please do not impersonate /prog/'s greatest hero.

..You could use two different sized LFSR's, two seeds, and an output length. but the trick would be in finding the seeds.. =)

>>45
Use a quantum computer to make XOR a reversible operation.

>>46 lol you know how xor works, right?
I had a look on paper, almost thought i had a 7 -> 6 byte compression, but probably not unless the 7th is a particular value... =(

Our hero has returned!

A few months ago I was contacted by an old client who claimed to have an algorithm which can compress any file to 20-30 bytes.  He asked if I knew what kind of customer would be interested in such technology.  I told him to look at Nigerian spam for a marketing model.  Never heard from him again.
