Re: New compression method
The judgment might be being made among some of you that the algorithm is automatically a failure since it cannot possibly compress all possible combinations of files to 515 bytes. The algorithm doesn’t have to be equally successful with compressing every class of file, and they don’t all have to be reduced to 515 bytes to be considered successfully compressed. The most “successful” compression technology becomes so by specializing in one class of file or another, e.g., imagery, text, object, and executable files. Our friend here hasn’t yet had the opportunity to run rigorous tests on the wide variety of files within even one class yet to discover the limitations of his algorithm.
This is a learning experience in developing an algorithm. Everyone can help as independent testers, with developing test procedures, mathematical proofs, test sets, critique, etc. Just keep it positive. The mathematical reasoning posted above is very good experience for Aalfabob and for any of us for the type of proof that will be required whenever you develop a commercially viable algorithm. Don’t be discouraged to uncover shortcomings of your method. Last edited by Mark McLeod : 10-09-2004 at 11:56. |

Re: New compression method
Isnt the formula combinations = bytes ^ values
so like a 512 byte peice of data ^ 256 possible charactors = 3.742e+693 combinations? edit - Nm got the wrong formula from someone. Last edited by Aalfabob : 10-09-2004 at 15:34. |

Re: New compression method
The one thing I have been wondering is if your magical algorithm calls on outside data (EG: using a dictionary outside the "compressed" file)?

Re: New compression method
Wow, I can't believe this thread has been running for this long. From the very first posts it was evident to me that this is a scam. The subtle mentions of financial gain. The need for patent money in order to make the big greens, etc... The interesting part is that one real chief delphi person mentioned that he knows aalfabob of this wonderfull compression scheme.
However, I realize odd things can come together once upon a time and that all of these scam-signs were inadvertent and aalfabob thinks he has this algorithm. If so then I apologize. However, I am 99.999% sure that such a bold compression scheme is impossible as was probably states a few times already in this thread. On a humorous note: take a look at this http://lzip.sourceforge.net/. I do so register my vote (opinion) as above on this issue. |

Re: New compression method
"Known issues with lzip 1.0:
Attempting to compress the lzip or lunzip programs themselves will trap your system in an infinite loop, and may cause the platter from your hard disks to shoot out of their drive bays at close to the speed of sound. Attempting to uncompress either of the exectuables will suck your computer into a minature black hole, which we believe from our benchmarks (speculatively) exits in an anitmatter universe parallel to our own. If you are interested in exploring this possibilty, please write to us once you get there. " off of the download section of the page. he was probably referring to that. I know it gave me a chuckle. hehe. as did the whole program being gzipped. =D Quote:

Re: New compression method
I had like a 3 paragraph post on how it was putting out smaller files and stuff but the server was down right after i sent it so it was lost.
But anyways, ive decided to let someone take a look at how it works and decide if they think it will work. You guys decide who you think would do the best job and the one I can trust. |

The only one thing I'm worried about is trusting you, what if you sent one of us something that would be potentially damaging to our computers. Don't get me wrong, I respect you, your ideas, and your claims, but I have a hard time trusting any stranger - you know how it is I'm sure. It's not you personally, it is any stranger to me. |

Re: New compression method
If you want a trusted party, please feel free to use me. I'm a CS and math major at Carnegie Mellon, so I pretty well know my stuff and would be willing to give an honest opinion. Also, my opinion tends to be pretty well-respected when it comes to programming issues around these parts. In any event, send me an email (FIRSTprograms@mn.rr.com) with the compressor/decompressor and I'll test it and post results to CD within a few hours.

Re: New compression method
You ummm really have no reason to trust me... no good rep... half decent programmer; not great like these guys... I can say you can trust me, but you can't really trust that.
I have nothing good to my name... well, except for this: http://vgamp.com/storage/fizixmanbig.jpg COMON! I'm a saxy beast, you GOTTA trust me now to do a good job with your code! <3 (plus your avatar is teh pwn... I'm going to steal it *stoled*) |

For what it is worth, my vote is to let Rob try this thing out. He is not only a long-time FIRSTer, but he has done tireless work to develop things for the FIRST community. He sees beyond his team and his personal gain. His efforts deserve the FIRST community's trust. Andy B. |
