Yes, that's right - my ISP unexpectedly (hopefully!) changed my IP.

It just started working again. Hmmm. It coincided with a reboot.
Did the IP address just change recently perhaps? This isn't dynamic
IP is it?

Can't upload completed tasks

zombi...@gmail.com (zombie67) — Tue, 02 Jun 2009 23:54:43 UT

According to the server status page, everything is running and green.

However, I cannot upload any completed tasks. Am I the only one
having this problem?

Re: Speeding up WE/WEP by testing multiple bases at once?

bear...@gmail.com (bearnol) — Tue, 12 May 2009 06:45:00 UT

...here is what it appears I have learnt about this latest adjustment
to the algorithm:
1) it DOES significantly speed up WE (so anyone using WE to factor
_general_ integers should use we2tr29 in preference to just we2tr2)
2) it DOES NOT speed up WEP any (because WEP already benefits from its
own special base-form, and this is not additionally preserved if the

Speeding up WE/WEP by testing multiple bases at once?

I've just had the above thought - and implemented it in Java [as a
small modification of my previous Java implementation of WE] - (very)
early indications are actually fairly positive - I'll let you know how
it goes...

Sincere thanks to yoyo, and his BOINCers over at yoyo@home:

who have been running some ECM curves, using GMP-ECM, on:
(M+2)2281, (M+2)3217, (M+2)4253, and (M+2)4423.
Look for an update to the main M+2 website soon, showing remarkable
progress - and hopefully even maybe a new factor!

To a small degree. I am asking for the average, of the two tasks. So
yes, there is a chance that some of the tasks get rounded up too
high. But the way it is now, they are all being rounded DOWN. So
HALF of us are being short-changed the way it is set up today.

Hi zombie67,
Thanks for your email(s).
Wouldn't that leave us exposed to credit-cheats?

I see that credits are based on the lesser of the two results. This
is a real penalty for Macs. Can this please be changed to the average
of the two?

Since I don't currently seem to have access to sci.math, I'm posting
this here for the record, and for your/our perusal...

I wonder whether (quite simply) this was what I was aiming at...:

thank you very much.

we got a discussion at [link] forum, about this

Well, it's (hopefully) recreational and educational! :) , but beyond
that...?
I suppose, if you're looking for more justification, also WEP-M+2 was
conceived to attempt validation of the WEP algorithm, which might be
useful in a mathematical sense...

What's the target?

deadjd...@gmail.com (Dead J. Dona) — Thu, 15 Jan 2009 11:43:33 UT

Well, what's the sense of those M+2 factors?

Lets say we find all factors for one particular M+2.

M=2^123-1 is a prime, M+2 divides by 12345 and 666 (stupid example).

And what? ))
