foreword by THE ABELSON.

he seems pretty excited tbh...i know im excited to read something new by the abelson

Abelson would use .tar.bz2.

FUCK! I wrote a lenghty reply wherein I RAGED about the triple archiving and retarded script kiddie formats, but then /prog/ decided not to load at all.

Not like it really matters, as no one would read your post anyway.

I was obviously referring to the dribble that you luckily failed to post.

I, for one, welcome our new Abelson & Sussman overlords.

I was surprised to see the Abelson speaking highly of other languages than the algorithmic language Scheme.

He didn't, since that reply was never posted.
Also, sage for the Anticudder and rars in zips in rars.

I obviously realized that and subtly hinted that you failed at posting a witty reply.

Abelson, unlike Sussman, is not a blind Scheme follower, and actually has a job.

Needs more compression.

Seconded, it's good that you compressed it a few times but it could be smaller for those of us who use floppies and want to fit more than just a file on it.

Actually, composed compression is pointless, since one application of compression is usually enough to remove most redundancy. I recommend you take a course in Information Theory before making a fool of yourself.

Actually read the foreword and you will see him praising the algorithmic language!

Depends. Most good compression algorithms (GZip, BZip) are composed of smalled compression algorithms. For example, BZip2 applies run length encoding two times, and then uses Huffman coding, along with a bunch of transforms in between.

So, technically, composed compression is part of one of the best compressors in the world.

Q.E.D.

Except that in practice, it doesn't work like that. Case in point, this file:

PDF: 3.4 MB (3579255 bytes)
First compression (RAR):  1.2 MB (1308773 bytes)
Second compression (ZIP): 1.2 MB (1310467 bytes)
Third compression (RAR):  1.3 MB (1314617 bytes)

So the file is actually considerably bigger than it would have been if it had only been compressed once.

Now do it again with rar.  Some formats compress better with certain kinds of data than others.

wow, rar sucks.
7z using LZMA (Lempel-Ziv-Markov chain-Algorithm) beats pretty much everything else by a large margin for compressing this file.

but the point was that compressing with one algorithm and then compressing with a different one sometimes results in a smaller file size than just compressing with one or the other.

Now do it again with PAQ.

Seriously though, the multiple packing has nothing to do with OMG OPTIMIZED. The inner rar/zip is for historical reasons, and the outer rar is added by the uploader who was too lazy to unpack/repack.

At least "classic" zip can't create solid archives, which is why recompressing a zip usually works. But raring zipped rars is pure faggotry.

using rar at all is pure faggotry.

>>20 here. I was (quite obviously) being sarcastic. I have worked on realtime PCA compression myself, so I'll pass on your offer, fool or not.

YHBT, go be smug somewhere else.
