Submission + - Writing filesystems now as easy as Web apps (reddit.com)

An anonymous reader writes: Remember the old days of writing Web apps, when you had to parse the CGI arguments separately, do all the safety checks yourself and implement everything manually? Neither do I, but it looks like all the cool stuff from Web apps is making its way to writing filesystems. This guy shows how to writing an entire Linux filesystem in 50 lines of Python using "dispatch" techniques totally stolen from Ruby on Rails. Are we ready to give up the Web and go back to just using the filesystem for everything, the way Unix intended?

Submission + - Patch Linux Kernel Without Reboots (zdnet.com)

evanbro writes: ZDNet is reporting on ksplice, a system for applying patches to the Linux kernel without having to reboot. ksplice requires no kernel modifications, just the source, the config files, and a patch. Author Jeff Arnold discusses the system in a technical overview paper. Ted Ts'o comments, "Users in the carrier grade linux space have been clamoring for this for a while. If you are a carrier in telephony and don't want downtime, this stuff is pure gold."
