Inspired by Jeff Waugh's Planet Gnome and a suggestion by Robert Love [interview], KernelTrap is now offering a feed of multiple kernel hacker journals. Thus, it's now possible to view the latest journals from several kernel hackers with one click: http://kerneltrap.org/hackers/linux
Journals currently included are from the following hackers: Robert Love, David Woodhouse, David Miller, John Levon, William Lee Irwin III, Arnaldo Melo, Greg Kroah-Hartman, Pete Zaitcev, Zwane Mwaikambo, and Patrick Mochel. I am very interested in adding additional journals, though for this to be possible it must be exported through an RSS feed. If you are aware of actively updated kernel hacker journals with RSS-feeds that I've not included, please let me know.
At this time I only include journals from Linux kernel hackers simply because as of yet I've not found any active non-Linux kernel hacker journals that have an RSS feed. As I find new active journals, they will begin appearing at the above URL.
Hopefully this new service will be useful to you. Enjoy!
