Re: Inane Stuff (Was: Mersenne: M38, SETI, and other random stuff )
Once again my apologies for lowering the tone, and many thanks for some sensible and thought-provoking responses! Following conservative estimates of cpu power and number of participants doubling every two years, I'd guess that we will have a our first billion digit prime in 2021, when we have 40 million participants and Pentium XV 1000GHz processors. 10^12Hz... wow! Can you imagine the technical innovation needed to get a machine where light only travels 0.3mm in a clock cycle? That's some densely packed, erm, stuff... probably not silicon, the sort of thing we probably can't conceive right now (electron obedience school?), but there's a good 22 years to go yet. Back in 1977, I seem to remember "VLSI" meant a digital watch was $100, now they're free with Happy Meals. As for 40 million participants, maybe they'll be giving away LL engines or Dubner crunchers with Happy Meals by then, maybe every electronic device in my house will be squaring and subtracting 2 in its idle time. I'm not counting on seeing either in my lifetime. Well, I still plan on seeing it in my lifetime. ;-) I'm with Spike on this one. If E.T. does make the call, there are going to be a lot of people dropping EVERYTHING. And even if we don't have "Microsoft SpaceBender V1.1a SR3" (courtesy of Bob Burrowes, thanks Bob) to make interstellar communication a possibility, there'll be a lot of people running for the cryogenic suspension chambers... Meanwhile, the potential M38 gets ever nearer... not long to wait now I shouldn't think. I hope Ernst or whoever is verifying will at least give us a yes or no answer, even if the EFF rules mean that the exponent won't be released to the world until it is in print...

Re: Inane Stuff (Was: Mersenne: M38, SETI,and other random stuff )
I'm on a roll tonight. Here's another one from me. Sorry guys, but this one was just too plain freaky to be a coincidence. The technical term is "superconductor" and I can conceive it quite fine :-) (This will probably provoke more cryonics postings.) I can see it now, George will be asking all you hardware guys how to optimize version 118 for the 65536-bit Intel superconductor architecture. The hardware guys better start working on this stuff, software guys like these sort of gifts :) Room temp superconductors... or we can pull a star trek and use the warp drive to speed up the speed of light and thus the optical components inside the CPU. (This is how the computers on the NCC-1701-D supposedly work...if you don't believe me, read the technical manual, available at fine bookstores everywhere and on multimedia CD-ROM.) And darn fine it is too. And all true ya know. There's only one leap of faith required for it all to be possible (subspace), ok, maybe the transporter is something else, but E=mc^2 makes that already seem like fact. I had to stop myself going into Star Trek mode on my last post. Paul saved me the embarrassment because I would have made a mess of it. ...maybe every electronic device in my house will be squaring and subtracting 2 in its idle time. I'd rather compute a Mersenne LL test. Erm, Paul it *is* an LL test. I forgot the mod N, but there's no charge for that :) cycles to exploring the Mandelbrot set, not some Julia set. And the Julia set in question here is the world's least interesting...just a line segment. ... and it's "*the*" LL test as well. Freaky, eh? But surely not the world's least interesting? Let's go Star Trek with it, this uninteresting, line-segment Julia set is folded in subspace (ok, modulo N space, it's getting late and I really need a trek fix right now) into an LL test. I just posted that... how strange. Great minds think alike, and all that. Square and add i and you get something a tad more interesting... like from a storm chaser's lucid dreams. A very different LL test, but still an LL test. A lucid dream, most definitely, but perhaps a catalog of all the Lucas pseudoprimes discriminant -1 (so of the form 4n+3)? have "Microsoft SpaceBender V1.1a SR3"... Now that would give a whole new meaning to "Internet Exploder". Can you spell "core breach"? "Gimme an M, Gimme an I, Gimme a C.". URGENT CORRECTION to the preceding Microsoft-related article. I love the list server when the "preceding article" arrives afterwards. Some relativistic effect, obviously. "Core breach" wouldn't begin to describe it. It would probably leave one of those subspace rifts that hangs around and swallows hapless ships long after the original disaster becomes last century's news... Or maybe worse. One might board the hapless ship and find Bill Gates rather than Montgomery Scott suspended in the transporter pattern buffer...

RE: Inane Stuff (Was: Mersenne: M38, SETI, and other random stuff)
My vote for "Most Inane" would be to the guy a year or two ago who claimed to know for an absolute certainty that there were only, (I think it was) 37 Mersenne primes. Whatever the number was, it was about one more than had been discovered at that point. -Original Message- From: Chris Nash [SMTP:[EMAIL PROTECTED]] Sent: Wednesday, June 09, 1999 8:32 PM To: [EMAIL PROTECTED] Subject: Mersenne: M38, SETI, and other random stuff Hi folks, As we all impatiently await verification of M38(?) a really stupid thought occurred to me, so apologies if it's a lot more ignorant than Chuck W.'s "definitive" post on the subject of GIMPS v SETI, or distributed computing in general. My apologies for being so inane, but I wonder whether the EFF *b*illion digit prime prize or SETI will happen first, too...

There are about 150 million primes less than 3.3*10^9, and at the current rate, we seem to do LL tests on 1/3 of them. So we are about 7.5*10^10 P90 years away from our first billion digit prime.
