secmartin writes "Dan Bernstein has just admitted that a security issue has been found in the djbdns software, one of most popular alternatives for the BIND nameserver. As part of the djbdns security guarantee, $1000 will be paid to Matthew Dempsky, the researcher that found the bug. The bug allows a nameserver running djbdns to be poisoned using just a single packet. Other researchers have found a separate issue that allows dnscache, the DNS cache that is also part of the djbdns package, to be poisoned within just 18 minutes when using the default configuration. Anyone using djbdns is strongly encouraged to patch their servers immediately." Reader emad contributes a link to the djbdns mailing list post containing both a patch and a sample exploit, and adds: "In the words of Dan Kaminsky (of recent DNS security fame): 'However, Dempsky's bug in djb's tinydns is way more surprising, if only because ... holy crap, he pulled an exploitable scenario out of THAT?!'"

cortex writes "I routinely need to analyze large datasets (principally using Matlab). I recently 'upgraded' to 64-bit Vista so that I can access larger amounts of RAM. I know that various Linux distros have had 64-bit support for years. I also typically use Intel motherboards for their reliability, but currently Intel's desktop motherboards only support 8GB of RAM and their server motherboards are too expensive. Can anyone relate their experiences with working with Vista or Linux machines running with large RAM (>8GB)? What is the best motherboard (Intel or AMD) and OS combination for workstation applications in terms of cost and reliability?"

Gary writes "NASA has paid $19 million for a Russian-built international space station toilet system. The toilet system, similar to the one already in use in the station's Zvezda Service Module, is scheduled to arrive at the space station in 2008 and will offer more privacy for a crew expected to double from three to six by 2009. The space station toilet physically resembles those used on Earth, except it has leg restraints and thigh bars to keep astronauts and cosmonauts from floating away. NASA says purchasing the multi million dollar toilet is a bargain compared to developing one from scratch."
