My machine display was acting strange when I got back to my box from over the weekend, and went to look at the kernel logs, and was shocked to see that they were totally overridden by this:

systemd-logind[3511]: Removed session 4168.
systemd-logind[3511]: Removed session 4169.
systemd-logind[3511]: New session 4172 of user rostedt.
systemd-logind[3511]: Removed session 4172.
systemd-logind[3511]: New session 4204 of user rostedt.
systemd-logind[3511]: New session 4205 of user rostedt.
systemd-logind[3511]: Removed session 4204.
systemd-logind[3511]: Removed session 4205.
systemd-logind[3511]: New session 4237 of user rostedt.
systemd-logind[3511]: New session 4238 of user rostedt.
systemd-logind[3511]: Removed session 4237.
systemd-logind[3511]: Removed session 4238.
systemd-logind[3511]: New session 4240 of user rostedt.
systemd-logind[3511]: Removed session 4240.

Decided to write a patch that would allow us to prevent user space programs from trashing the kernel logs. (This is a much kinder version of my "debug" patch from before)

Thinking about it, it seems that Linux user space in general have become very fragile. If i was to speculate i find myself thinking that the shift from using files and socket to using dbus is a big contributor, as dbus seems highly adept at shitting itself at minimal provocation.

And recently i learned that Fedora/Gnome/Freedesktop wants to cram video streaming through dbus...

I wake up this morning and see the "check-in" reminder from American Airlines. As I never do the early check-in thing, I usually ignore it. But this time I looked and noticed it said my flight was at 6am!  I double checked my email verification and it said 11:15am. I logged in, and sure enough, it said 6am. I called to find out what happened. The 11am flight no longer exists (I fly from my regional airport), and they moved my flight to 6am (there were seats available then). They moved my BGM->PHL flight and my PHL->PHX, but my PHX->PDX was still the same, leaving me a 10 hour layover in Phoenix. I bitched about that, since they moved me and I didn't want a 10 hour layover, they were kind enough to move my PHX->PDX up so that I arrive in PDX at 4:45pm instead of the original 11pm.

OK, so I have to wake up at 4am, but now at least I don't arrive late at night for an early morning conference. That flight was originally $200 more than the one I booked, thus I guess everything worked out in the end.

hmm. So does American not send you an email for schedule changes? I have had it happen for another ticket and realized it just by mistake.

No Mr. Ballmer, you were correct. Linux was and is a cancer, and it has just spread to the Microsoft Lymph nodes.

After watching +Karen Sandler's talk at ELC, she convinced me it would be a good idea to become a supporter of the Software Freedom Conservancy.

I really wanted to her talk since I am already a supporter. But the usual conflicts came up. I'm looking forward to the video.

Anyone who may be in San Diego next week can come and see my talk about understanding Real-Time systems. You have to register with the Embedded Linux Conference to do so.

The Open Source Community can be inspired by Dr. Tyson's comments on this subject as well.
