Hello everyone: NO, I didn't miss the DE-compressor reference, I read it
|
| |
I'm not sure what I can say here, not that I imagine that anything I say would convince you. Here goes... First, portions of the system are asymptotic, seeing or understanding one gives you the other with a few seconds thought. And second, most important, I am leaving out something -- a major fact. Something that were I to say it. or even to hint at it, I'd... more »

Need help with getting started with Data Compression libraries
|
| |
Hi All, I have an application that sends data over the Internet to authenticated clients. In order to get around issues of bandwidth, I have to modify the code of the application to compress the data before it is sent across. Could somebody give me tips on how to get started with the best text data compression libraries for this purpose?... more »

about perpetual compression, bogus patent filing, recent claims
|
| |
Well, compressing many times, at least -- of course, nothing in our natural world is truly perpetual. I've been reading some of the posts wrt certain recent claims. Since I've actually done it, built 'perpetual' compressors, that accept and re-process random input to produce a smaller output file, I can say... more »

Entropy very close to maximum
|
| |
Arithmetic coding is the best solution (as I know) to compress data close to it's entropy. I have newer implement any arithmetic coder, that's why I could not get, why it's just close, but not the entropy itself. Can anybody explain in a few words, what is the problem with that? I am focusing on this because there is such thing like factorial...... more »

Pete's Really Intensive Compression Kaper
|
| |
I now know how to compress any file to 50 bytes. The file can be of any length, and random data compress well. Step 1 - take your binary file, and invert every "1" bit. Make an note in the command section to encode the position of the original "1" bits. It is well known that command sections never exceed about 50 bytes.... more »
