Re: Mersenne: Here we go again.... v22.12 now available.
- Original Message - From: George Woltman [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, November 09, 2002 4:29 AM Subject: Mersenne: Here we go again v22.12 now available. This bug did not cause all factors to be missed, in fact it could cause some factors to be found that ordinarily would not be found. Specifically, in this low-memory situation prime95 steps through the range between B1 and B2 in multiples of 210. When processing a prime p, the code actually included the prime mirrored around the previous multiple of 210. For example, if 21+1 is prime, then 21-1 was improperly included. If 21+3 is prime, then 21-3 was included. How could this lead to factors being missed?

Re: Mersenne: Ernst Mayer's GIMPS pages
You probably were about to do this, but... Add a line like this to the BIND zone file. (I see you're the SOA contact in the hogranch.com DNS zone, so should have access to this.) IN A 204.182.56.143 This is like: www IN A 204.182.56.143 Zone file is probably /etc/named/db.hogranch.com Then you'll have an address record for hogranch.com as well as www.hogranch.com and all existing links will work.
