An anonymous reader writes "Ksplice, the technology that allows Linux kernel updates without a reboot, is now free for users of the Fedora distribution. Using Ksplice is like 'replacing your car's engine while speeding down the highway,' and it can potentially save your Linux systems from a lot of downtime. Since Fedora users often live on the bleeding edge of Linux development, Ksplice makes it even easier to do so, and without reboots!"

ArbiterOne writes "The 11th Annual System Administrator Appreciation Day is today. Celebrated worldwide on the last Friday of July, this day honors those who fight in the digital trenches to keep the Net alive. OpenDNS offers a way to remind your boss about the holiday, while another blogger shares war stories. The startup Ksplice has created an homage to these heroes in the style of Choose Your Own Adventure." Reader Netbuzz submits a sobering look at the profession from Network World, which notes, "In the past year, [sysadmins'] pay has dropped, and more of their positions are being farmed out to temporary workers."

An anonymous reader writes "Ben Bitdiddle of MIT fame sends an open letter to system administrators encouraging them to stop patching their systems so they can play 'Security Vulnerability Bingo.'"

Hanji writes "We have discussed here before the potential effects of and protections against cosmic ray radiation, but for the average computer user, it's an obscure threat that doesn't affect them in any real way. Well, here's a blog post that describes a strange segfault and, after extensive debugging, traces it down to a single bit flip, probably caused by a stray cosmic ray. Lots of helpful descriptions of Linux debugging techniques in this one, and a pretty clear demonstration that this can be a real problem. I know I'm never buying a desktop without ECC RAM ever again!" The author acknowledges that it might not have been a cosmic ray-based error, but the troubleshooting steps are interesting no matter what the cause.
