Re: Mersenne: Dissed again
I would be in favor of a screen saver version as long as it can: a) run in the non-screen saver background (as it currently does) b) have the screen saver option disabled c) have same pretty screen accessible via menu for us geeks to check periodically So us geeks can run it faster and mainstream users can watch pretty colors. - Original Message - From: Brian J.

This has been mentioned many times before.
Re: Mersenne: On v18 factoring
Is there any kind of assignment that will force the client to try to calculate a divide by zero and crash? Or would other safe testing still be desired? <><><><><><><><><><><><><><><><><><><><><><><><><><><><>Subscribe to The Gann Letter if you are interested in:varying levels of humor/jokes/quotes, parody/satire,science/space/technology items, cool news, games,programs, pics, and other interesting stuff. subscribe #1: [EMAIL PROTECTED]subscribe #2: http://groups.yahoo.com/group/TheGannLetter/joinsubscribe #3: gann (at) ganns.comread online : http://ganns.com/TheGannLetter<><><><><><><><><><><><><><><><><><><><><><><><><><><><> - Original Message - From: Brian J.

Perhaps in a few weeks the server can be updated to return an "out of> exponents" error to v18 instead of offering it an assignment it can't> handle?This is not trivial - if you do this then a "broken" client will probably request another assignment immediately - thus trapping the client and the server into a vicious circle. Whilst the client can go hang for all anyone else cares, the effects on the server would probably be much the same as handing out an "unacceptable" assignment.Other people have mentioned the possibility of "automatically" disengaging or updating the client. I have very serious reservations about this; the problem is that it leaves the system hosting the client wide open to use of the mechanism for malicious purposes, e.g. "updating" to a client containing a trojan or switching it to a different project, or attacking a user by disengaging his systems so that you can leapfrog him in the league tables. I'm afraid that I would have to withdraw my systems from the project, and recommend that other people did the same, if any such capability was added to the client.Given that the server can tell the difference between a v18 client and a later one, would it not make most sense to have the server assign a LL test on the _highest_ unallocated exponent which v18 can handle if a v18 client asks for a factoring assignment and none suitable are available. This action would effectively remove the client from the loop for a while (probably a few months, given that most v18 clients will be running on slowish systems), thereby alleviating the load on the server, and buying time to contact the system administrator - when this is still relevant, of course. And some useful work may still be completed, eventually!RegardsBrian Beesley_Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htmMersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
Re: Mersenne: Dissed again
Well, you're going to love this [links below]. The Google Toolbar has a new icon today stating that it had updated itself. Reading further shows that one of the updates is the ability for Google Toolbar users to automatically run the Folding@Home distributed computing effort. I am guessing there are at least many thousands of Google Toolbar users and a fair percentage of them will find this "new" distributed computing thing interesting; maybe even 5-10%. Regardless of the actual number, Folding@Home is going to receive a huge boost from "Joe and Jane web user" just because they were not previously educated on other distributed projects and this one happened to fall into their lap. I initially am jealous of the free boost that Folding@Home will receive, but at least maybe a tiny percentage of Joe's and Jane's will find their way to us now that they have been introduced to distributed computing. Someone mentioned marketing. It appears that Folding@Home simply found a large userbase already attached to a neat tool, then cut a deal. http://toolbar.google.com/dc/aboutdc.html http://toolbar.google.com/dc/faq_dc.html#about8 Erle Greer Evangel University Webmaster <><><><><><><><><><><><><><><><><><><><><><><><><><><><> Subscribe to The Gann Letter if you are interested in: varying levels of humor/jokes/quotes, parody/satire, science/space/technology items, cool news, games, programs, pics, and other interesting stuff. subscribe #1: [EMAIL PROTECTED] subscribe #2: http://groups.yahoo.com/group/TheGannLetter/join subscribe #3: gann (at) ganns.com read online : http://ganns.com/TheGannLetter <><><><><><><><><><><><><><><><><><><><><><><><><><><><> Quoting "E.
