Large inodes = faster samba
Ted T'so just mentioned in his LCA 2007 talk that larger inode sizes improves the speed of Samba 4. This is because you can fit more file attributes in the inode. I can't find a reference to the benchmark results online quickly, but wanted to make a note of this.
Mirror traffic during the last day of LCA 2007
It seems obvious to me that videos of LCA 2007 are good.

Errata: Tweak to homework, new VMWare image
It had to happen. I screwed up the ffmpeg installation in the homework for the tutorial, so the tutorial page now has an errata section which explains the problem. Additionally, if you downloaded the VMWare image before now, you'll need to download a new copy. Sorry for any pain caused.
Wrong timezone batman!
Heh, the LCA2007 planet is running in a timezone offset from Sydney time by one hour. I wonder how many people that will confuse? Oh, and holy crap does it aggregate quickly.
Am I really the first?
I find it a little hard to believe I am the first to use an Intel Core 2 Duo for MythTV stuff, but I can't find anyone else reporting this to the MythTV users list... mythtv@mythtv2:~/Desktop/mythtv-0.20$ ./configure *** WARNING *** Your CPU was not detected properly: uname -m: i686 uname -p: unknown model name: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm If you are using a recent CVS checkout, please e-mail the above to mythtv-users@mythtv.org With the subject "configure did not detect my cpu"
Updated: linux.conf.au 2007 MythTV tutorial homework
The final version of the MythTV tutorial homework is online. I promise no more changes now (unless they're minor bug fixes), mainly because I get on a plane in 9 hours to come to Australia. Note that the bottom of the homework gives the details for a VMWare image if you're too lazy to do the homework. See y'all at LCA!
Updated: linux.conf.au 2007 MythTV tutorial homework
I spent the afternoon updating the linux.conf.au MythTV tutorial homework. I did all the homework on a VMWare virtual machine, and it took me about four hours to complete, given that compilation was slow for me in the virtual machine, but downloading was fast. Next steps are adding ffmpeg setup to the homework, and putting the finished virtual machine online so that lazy people can just download the crazily large file.
For Christmas I would like…
One of these things in every room at every open source conference. Get on that please.
First cut of the tutorial homework is ready
Stewart and I are just now putting the finishing touches on our MythTV tutorial for linux.conf.au. Because it's a tutorial and is therefore meant to be hands one we want people to come along with a machine which is configured so it can take part in a bunch of the demos. To that end we have set homework! Note that it's currently a draft, because I'm pretty sure there will be some stuff in there about ffmpeg, but I wanted to get it out so that people can get an idea of what we want to cover, and get a start on the homework. One other option is for me to make a VMWare image of a machine once all the homework is done available. Would people find that useful? It would be pretty big.
