If you're saying what I think you're saying, you are:)
If i get you right, you get a bunch of hashes (crc, md5 etc). You then transmit them to the recipient who generates a list of all files that each could represent, and finds the one that is in all lists. Superficial objections: very slow, large amount of disk space, hashes may not be reversible except by brute force which is unthinkable (hash all possible n-byte files and look for this).
Deeper objection: this does not seem to take advantages in patterns in the data, and this is the only way compression can work. If n bytes can be compressed into n-1, then the data is redundant. Therefore, if this method works, it should work for everything. This would then compress everything, which is impossible, even more so (!?) since every compressed file would have the same size. To see why, compress all 256^N n byte files into B byte concatenated hashes==compressed files (less than N bytes). For the process to be reversible, the compressed files must be unique, however there are only 256^B
Executive summary: compress all possible files, they are all smaller. There are not enough smaller files, so compressed files are not unique. Thus it is not reversible.
The result of this is that compression will (on average) mean that there is more than one file satisfying all hashes. For a unique file satisfying all hashes, on average the total hashes will be at least as big as the file.
How much more helpful could I be than to provide you with the appropriate e-mail address? I could engrave it on a clue-by-four and deliver it to you in Chicago, I suppose.
Funniest thing i've read in a long time. Like my new sig?
This is old news and i think i've seen it posted on slashdot before. You people don't get out much, do you. A star-orbiting was sighted a long time ago, when Adam made headlines by saying "Huh? Whats that thing under my feet". It has been known to be revolving around a star since the time of Copernicus and people have been making pictures of bits of it for centuries.
AMD and Intel have processors running at 2+ times that clock speed.. gimme a break.
That is *exactly the point* I remember a while ago (when the G4s were quite new IIRC) apple had a thing about the new chip being a pentium killer. They did some tests (yes i'm sure they were biased but the point stands) that showed the G4, with less MHz, ran just under 3 times as fast as the pentium, although the pentium had a higher clock. Remember, stuffdone/second = stuffdone/cycle x cycles/second. These chips were doing (at these particular tasks) just over 3 times as much as the pentiums in each cycle.

What?
There will be a standard, SINGLE image of Linux in the brains of most consumers
That would be a start, it beats NO image of linux, which is the case with most consumers now.
I recommend keeping all linices entirely without involvement by non Linux corporations
1) Great, but it's as much AOL's software as it is yours.
2) If they are non linux corporations, they are not involved.
What, judging by the fact that intel.com gets more hits than baywatch.com?

Well, there isn't a huge company with a monopoly on operating systems trying to squash it.
Well I'm glad you control the stereo in your house. Some of us have 13 year old sisters :(
*40:2*? Holy shit! This could save my company $80m/year! We thought our 20:1 was pretty good but THIS!

Yes, they can and are.

No, really I was just replying to someone elses spam, but i guess the reply address was the mailing list. Copy of message follows:

No, if you want redundant, there was a program on here in NZ called backch@t.
I assume that it's based on the similarity between Mobilix and Obelix, not just the -ix suffix.
In other news, Simpsons creator Matt Groening announced plans to sue all Bartenders, margerine manufacturers, and Grampas.

When i say picture, i mean ascii art.
OMG i've got it! It's a picture of the tall black monolith off 2001!
No local storage? Then where will you put the ram? This guy is nucking futs...

Or hire a fake critic to give praise?
And yet they omit to mention that somethimes it gets cold in Canada in the winter?

Hertz aint everything.
Sure, the floppies are out of fashion, but that's no reason to *deny the existance* of the number 5 1/4!
The point is that I can now justify my fear of custard.
