(Mostly) Confirmed: New Mersenne Prime Found

Hemos posted more than 12 years ago | from the one-more-down-another-to-go dept.

Science 331

A reader writes "Distributed computing seems once more to be succesful. The combined effort of many pc's joining Primenet in search for a new Mersenne prime may have found there fifth result. Among them many belonging to /. readers. There is an unconfirmed claim for Mersenne prime #39 of over 3,500,000 digits, for which a considerable amount of money has been awarded. SETI looks for ET's messages, but found none sofar. Mersenne primes are used to tell ET about us. A previous found Mersenne number was used to show the advance of science on our planet in a message send into outer space. " The Primenet list has confirmed that while they still need to totally test it out (which should be done by the 24th), they believe that the number found today is the 39th positive.

Back in Jan. 2001 they sold the developer version, it was expensive (~$700 or $800) but it was available(sold-out now). I seen quote a bit of discussions from people that had purchased them. They just seem REALLY late in getting the final consumer version out.

(User #532907 Info [slashdot.org] | http://www.geocities.com/trolltuesday2k1/ [geocities.com] ) Unfortunately, buying a YOPY requires MONEY. The Slashdork crew is unfortunately "low" on money, due to the fact that they are untalented wannabes eeking by on modest banner-advertisement revenue. The stock options which they once thought would be their tickets to success are now worthless -- and rightfully so; it is preposterous that such lazy losers should make money without doing any actual work.

Rob Malda, the wannabe hacker and latecomer otaku, will soon be out on the streets, begging for spare change by the traffic light. He will spend his nights in a local shopping center, rubbing his ass against the shopping carts for kicks.

Jeff Bates, the wannabe scientist, will be forced to pimp out his little wifey -- amusing, because she's been an amateur whore for so many years already. Bates's primary customer will be Malda, whose Quarter Cartel shall make him one of the most prosperous bums in shopping center.

Gay Nik, although never really part of the Slashdork crew, will join this merry gang of homeless beggers, too, because what questionable BSD "skills" he many have are worthless in this day and age, a day and age in which *BSD is dying. (OpenBSD will never lose any users, though, because the only users it ever had were Theo "The Rat" De Raadt and his canine lover, Farmer.)

Jon Katz, a man who couldn't write an interesting article to save his life but whose knowledge of Microsoft Word's "spell check" facilities makes him a twerp among lamers at the Geek Compound, will make his living by designing the Slashdork crew's "Homeless, five children, please help, godbless" signage. Interestingly enough, the signs prove more of a challenge to Katz than any of the meaningless drivel that he ever spewed while leeching off of Slashdot.

CowboyNeal would be able to subsist on his own fat stores for approximately fifty years, if he weren't destined to be harpooned and eaten by a gang of minority squirrels.

Timothy Gaybone, Michael "Censorship NAZI" Himmler, Jamie "Gay Nights Online" McCarthy, Emmett "Stupid" Galacticon, and Krow the Wannabe DBA will also reside in the shopping center, and provide blowjobs on demand to the local "nerdcore" [geocities.com] [geocities.com] fetish group.

Has anyone had any experience porting KDE apps to a portable like this (one that uses QT-embedded I assume)? The article didn't mention a JVM (at least not that I saw), but that could be a big way to drive application development for PDA's in general. If you could write one simple little app in java, and have it run on PocketPC 2002 (Via the Geode JVM), on the Yopy, and on the new unit from sharp. That's really the only stumbling block I see to Linux PDA's doing great things is applications. Nice pretty user-friendly applications, and lots of them.

-A BIOS that handles power management and screen taps, as well as a fairly safe routine for handling flash functions
-Easily swapped OS
-Versatility of an iPaq, batteries of a Palm (rechargeable is best
-USB cradle

Put that out as an OEM device. You can even ship it with WinCE if you like (PalmOS 5/ARM would probably be a better choice of course), but make sure the world knows you can hack it.

The assumption is that if ET is out there, he's a lot more technically advanced than we are. Human civilization has been around for, oh, call it 8,000 years. The universe is more than a million times that age. So ET has a big head start.

My theory is that the universe is teeming with life, but everyone else is smart enough to keep a low profile. Only the humans like to broadcast to the universe an exact measure of how technically backwards we are.

Generally such messages are designed to illustrate mathematical concepts. As such, I highly doubt they only sent one particular prime.

They may not even share our fascination with prime numbers - while eminently useful to us, they aren't nessecary for things like engineering.

[So what if ET] hasn't found this number is prime yet? Won't he/she just think this 3,500,000 digit number is a bunch of gibberish?

They'll probably figure it's our Galactic ICQ number.

Seriously speaking, if they think at all like us, they will figure that the number has some special property and start testing it. Testing a number for primeness goes much faster than searching for new primes. Having discovered that it is indeed prime, they will know just how clever we are and hopefully be so impressed that they will decide not to devour us.

Just thinking about all the time, money, and CPU power that went into this disgusts me. While a prime number with 3,500,000 digits might have a nice cool factor, it is completely useless for any practical purposes.

Right now, there are literally millions of people who are suffering on this earth, and the vast majority of those problems can be solved by science. We should be focusing our resources on curing disease, engineering more productive grains and vegatables, and discovering cleaner power sources rather than pissing away millions of years of CPU time trying to see who can come up with the biggest prime number.

And if they don't, but have superior technologies - it's like sending them a message "Hi - we have inferior technology - come colonize our planet".

First: distributed computing achieving something great. Don't get me wrong, I'm all for SETI, I've got it running on both my machines ... but being able to advance science be it math or cancer research or whatever is astonishingly cool.

Second: it's entertaining to think we can prove our intelligence to another species by sending them proof that we've cracked a prime ... If they're astonishingly more advanced than us they'll look at it as being quaint and if they're not they'll look at it as something they can't understand. How would we react if something landed that proclaimed how smart the sender was?
Of course, if they're "looking" at the wrong frequency or in the wrong band they won't see it at all... so many assumptions... so little time.

If ET doesn't understand mathematics, its unlikely ET progressed as far as building radios, either. Prime numbers are a fairly simple mathematical concept, one thats been found by every human society developing a complex system of mathematics. It's not simply some artifact of the decimal system. Prime numbers are prime in any base. Once you've got whole numbers and division you're pretty quickly going to come to the conclusion that some of them can't be divided by any of the others.

A critique of the news item. (-1)

Sunken Kursk (518450) | more than 12 years ago | (#2565809)

A reader writes "Distributed computing seems once more to be succesful. The combined effort of many pc's joining Primenet in search for a new Mersenne prime may have found there fifth result. Among them many belonging to /. readers. There is an unconfirmed claim for Mersenne prime #39 of over 3,500,000 digits, for which a considerable amount of money has been awarded. SETI looks for ET's messages, but found none sofar. Mersenne primes are used to tell ET about us. A previous found Mersenne number was used to show the advance of science on our planet in a message send into outer space. " The Primenet list has confirmed that while they still need to totally test it out (which should be done by the 24th), they believe that the number found today is the 39th positive.

I wonder if this "reader" is an anonymous coward or really an editor not wanting to take credit for his grammatical mistakes. The content of his writing clearly shows ignorance to the subtle differences between "Their" and "There", as well as the inability to recognize either verb tenses or sentance fragments (Take your pick). Also, the fragmentary nature of the second half of their (see, someone can use "their/there" correctly) demonstrates that this person forgot to take their Ritalin today.

Re:Decss? (1)

Neon Spiral Injector (21234) | more than 12 years ago | (#2566015)

First it was a .gz file that was the prime number that gunzip'd into DeCSS. That is relavant because .gz files can have an arbitry amount of junk tacked on the end and still be valid. So the person just gzip'd decss.c and then added enough junk to make it into a prime number.

Second a Mersenne prime is all bits 1, so you'll never have a valid gzip header to start with.

So no luck there. But if you were to gzip the number it would compress up real well.

Seriously -- not speaking from a naysayer standpoint or as somebody who thinks that SETI is a complete waste of time, although I am both of these -- what if ETs don't do math?

I know, it's hard to fathom. But imagine this: human appreciation of art and life is rarely build on logical thought. When I say that my favorite painter is John Kacere, it has nothing to do with the trigonometry of his brush strokes and everything to do with what I like, a much more concept ideal. Conversation is a way of attempting to apply logic to what is essentially an illogical process, to explain a biological reaction with words and phrases.

So what would I think if Chewbacca beamed a thirty meg prime number into my PowerBook? I sure as hell wouldn't pick up instantly on its nature. I'd probably try and run it through a gif converter or play it on Audion before I'd think to perform the three year process that would uncover it as a prime number. If we're trying to make contact with primes, it seems that we're restricting our target intelligence to creatures smarter than me. Which seems defeatist. Why not start smaller, with a fibinacci sequence or the differential calculus or a DivX file of "The Facts of Life" (divx having been developed in less than a year)? Don't we realize that they'll want to check our math even if they do figure out what the stream of gibberish we're sending is all about?

And finally, what are they going to think when it gets there? Ifome superintelligent race of beings gets a message of a fact they already knew from a race of eggheads in the unfashionable end of the western spiral arm of the milky way, they're not inviting us to the intergalactic luau -- they're taking that hot race of Beings of Pure Sex from Omicron Six!
