IQ Test
So our Friend's the Mauery's posted their test scores so I had to try it. Not to bad considering I guessed on a few, I made it into the "Gifted" category. Lots of advertisements trying to get you to sign up for stuff at the end before they give you your score though. You can wade past it all but it takes a while.
Linux Plumbers Conference 2008I spent the latter half of last week at the Linux Plumbers Conference in downtown Portland. And despite being a new conference, I found it to be one of the best conferences I've attended. I think this might be in part to its small size, there was a much better average developer to community leader ratio than at other conferences, indeed some of the key leaders don't even attend some of the larger conferences. The fact that LPC piggy-backed on Kernel Summit had a lot to do with the turnout. So what was exciting?
While there was a lot of great content, the things that stood out to me were: From Naught to Sixty in 5 SecondsArjam van de Ven and Auke Kok shared their work on getting Fedora and Ubuntu to boot in under 5 seconds on a netbook. While the SSD drives were key here, they still could do 10 seconds with rotating platters. Key bits including Super Read Ahead, disabling everthing you don't use, and picking on everyone that wasted boot time :-) Canonical took another hit here for GDM taking 3 seconds to start (60% of their total schedule!) due to storing massive pngs that it scaled down at each run to fit the current resolution. Definitely plan to look at my boot process and see if I can knock a few 10s of seconds off. Git TutorialSo was this cool only because it was Linus presenting? Yes and no. Linus is actually a great presenter. He is bright (duh) but also witty and engaging. He had no slides and simply walked the room through some git usage. While most everyone in the room had used git before, no-one seemed ruffled by it. It was nice to hear first-hand why git is the way it is. Did I come away from it loving git - uh... no. But it did clear up some of the issues I had with it - mostly by correcting my perspective on how it should be used. Graphics Drivers in the Kernel: 20 Years LateDave Ailie and Jesse Barnes (among others) discussed the work being done to move video drivers into the kernel (from xorg userspace where they are now). Specifically memory management and mode setting. There was some good debate between the speakers and Linus, which ended with three of the speakers simultaneously stating "Well, you're wrong!" to the chief penguin. There was a good chuckle from the crowd, things usually go the other way. The presenters knew their work, they knew the interactions of the various pieces, and they were able to defend their approach which Linus didn't accept at first. His pragmatism was very apparent during the discussion and his drive toward simplicity made very clear. An excellent discussion. So what does this mean for users? hopefully those of us with the right chipsets will not have to watch our screens struggle through resolution changes 3 times during a single boot :-) Hallway DialogWhile the formal talks and discussions were great, the best part of any conference is the one on one time with the people you work with over email and irc the rest of the year. For me this was a lunch with Thomas Gleixner, Steven Rostedt, and Gregory Haskins. We discussed the problems pthread condition variables have with priority inheritance, and formed a game plan to get the solution moving forward. It's a tough problem, and largely logistical in nature rather than technical. Changing APIs (and ABIs) at the glibc level is a painful process (for good reason). All in all, it was a great conference. A lot of good discussion between the developers of various systems was had (which was of course the intent). Thanks to IBM for letting me attend, and thanks to the organizers who donated so much of their time to the event.
Let there be light!
Security Catch-UpOK, so while all my co-workers took a half-day to check their systems for each of the openssh and dns exploits earlier this year, I foolishly let it slide, thinking I had more important things to do. So while I didn't procrastinate so long as to get hacked/phished/etc. I did wait until tonight. So after a few hours research (and a couple educational jems, I've finally regenerated all my system's host keys and have deleted all my .ssh keys and regenerated them on systems where I have console access, relying on ssh agent forwarding everywhere else (thanks Josh). As for DNS, I've redirected my router to opendns which is looking to be an excellent service (thanks John). So I should be all buttoned up again...
Wicd! Wifi Management that Works!It's a very novel concept I know, but the guys at wicd have managed to write a wifi network manager that does things like remember your WPA key (unlike some other more common NetworkManagers). I still need to see if it can do really complicated things like save a config for a hidden network (ooooooh!) and handle enterprise authentication (LEAP), but for now I am very happy to have replaced NetworkManager with something that appears to just work. Check it out: http://wicd.sourceforge.net/. Now, how 'bout it Ubuntu, can we ditch NM already - isn't two broken release cycles enough?
Planting Party!

Streaming Media to the PS3 with MediaTombI've been enjoying streaming music to my Playstation 3 with the most excellent MediaTomb uPNP DNLA Media Server for a while. Tonight I managed to get MediaTomb to present the MythTV recordings in a format the PS3 could actually understand. I used the Cidero UPnP A/V Controller to debug the XML presented to the UPnP client by the server. Turns out the PS3 prefers video/mpeg over video/mp2p for MPEG2 video files - picky picky. Simply adding the following: <map from="mpg" to="video/mpeg"/> to the MediaTomb config.xml and removing/adding the recordings folder got my PS3 streaming video from MediaTomb. Excellent!

Fun in the SunParks So this summer I tried to do a weekly park trip with women in our yard. There are a few pictures of one park which turned out to be lots of fun. Water, sand, and spinning toys -- Devon was in heaven. Also included are pictures of Devon and his Friends Nicole & Nathan playing at the big tree house play structure at the outlet mall. They had a grand time and Lauren got to shop in peace. Devon loves being able to get out and move around, climbing, jumping, running, spinning, rolling, tossing,... the list goes on so I am glad that Portland has so many great parks -- now if his mom wasn't so lazy and would take him more often.
