The video of the kernel report is cool. It only has left hand audio though. I wish people would ask questions using the microphone though.

LCA 2007 Video: CFQ IO
I’m watching the CFQ IO Scheduler talk now on MythTV using my MythTV program downloader thingie. Beware the very large audio volume jump about three minutes in. Just saying.
Oh, and the “pan across blank blackboards for a bit at a funny angle” thing at around 6 minutes is pretty amusing too.
Update: now with working URL for the downloader thingie!
Mirror traffic during the last day of LCA 2007
It seems obvious to me that videos of LCA 2007 are good. Specifically:

Yay for LCA 2007 videos.
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.
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.
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.
Hypothetically speaking
Hypothetically speaking, if you needed to write a four hour long presentation (probably around 200 slides), shared with another speaker, and wanted to keep the style consistent and conforming with your approved corporate style, how would you do it?
I’m thinking of some sort of intermediate language, which can then be used to generate slides from a template? Is there anything like that out there?
