Submission + - Nominum calls Open Source DNS 'a recipe for proble

Raindeer writes: "In an effort to promote its new Cloud based DNS service SKYE, Nominum one of the commercial DNS-software, providers slaundered all open source/freeware DNS packages. It said: "Given all the nasty things that have happened this year, freeware is a recipe for problems, and it's just going to get worse.(....) So, whether it's Eircom in Ireland or a Brazilian ISP that was attacked earlier this year, all of them were using some variant of freeware. Freeware is not akin to malware, but is opening up those customers to problems. " This has the DNS community fuming. Especially when you know Nominum was one of the companies affected by the DNS Cache poisoning problem of last year. Something PowerDNS, MaraDNS and DJBDNS all open source weren't vulnerable too."

Submission + - Why Is Linux Notebook Battery Life Still Poor?

Ganty writes: "I recently purchased a Lenovo W500 notebook and after 'downgrading' to XP and creating a dual partition I found that I had a battery life of nearly three hours using the long life battery, at this point I was a happy camper because it means that I can watch a DVD during a flight. I then tried various Linux distributions and found the battery life under FOS to be VERY disappointing with an average of 45 minutes before a warning message. After settling on Ubuntu I then spent three days trying various hardware tweaks but I only managed to increase the battery life to one and a half hours.

Unwanted services have been disabled, laptop mode has been enabled, the dual core CPU reduces speed when idle and the hard drive spins down when not needed.

Obviously Apple with their X86 hardware and BSD based OS have got it right because the Macbooks last for hours, and a stock install of MS Windows XP gives me three hours of life. Why is battery life on notebooks so poor when using Linux? Some have suggested disabling various hardware items such as bluetooth and running the screen at half brightness but XP doesn't require me to do this and still gives a reasonable battery life.

What have I missed?
