Video: Ted Ts'o on Ext4, BtrFS and first steps with Linux
Linux Magazine Online took the opportunity of Fosdem 2009 in Brussels to track down and talk to kernel developer and CTO of the Linux Foundation, Ted Ts'o.
Ted talks about the improved acceleration of ext4 and the difference between ext4 and BtrFS. He explains who actually pays him, and why he's on assignment from IBM. Subsequently, Ted reminisces about what he did with Linux when he first discovered it in the 1990's.
Theodore Ts'o has been assigned to the Linux Foundation for two years. As CTO, the Californian works mainly on the ext4 filesystem, which he says can be regarded as stable since October last year when it became part of the Linux kernel. He's also accompanying the development of the extended filesystem, (ext), that has been continuously built with backwards compatibility in mind.

Can I Get A
Thank you!
flash...
Thanks for the wget-link.
Nice video. And please, stop bothering.
P.S. as for "open" formats... Flash specs are here. Furthermore, video stream specs and GPLed encoders\decoders are ALSO here. So if you do not want Adobe, you can use for example wget + any player you like. And about Theora.... right now it's incredibly crappy codec. It loses to simplest MPEG-4 like XviD. And it beaten to the hell by things like H.264. In my country there is no such moron things like "software patents" so it is perfectly legal when I'm using GPLed codecs. Am I expected to download video which is twice more in size but still loses in quality just because USA guys can't cancel software patents up to date? Thank you very much but NO. Let's these USA guys to deal with their stupid issues themselves. So if you do not like software patents, just do what you can to cancel them. They're used mostly by patent trolls anyway. Look, Red Hat attacked by patent troll, etc. It is not codecs what have to be fixed. It is moron USA laws...
please take example from ted.com that have ogg links under the videos
Ogg
Please think of the children...and other people in the future studying filesystem design..
There could at least be a second link to an alternate encode of the video.
Plea for Non-Proprietary Video
People just want to be able to watch the people. PERIOD
Lets face it, there will always be a mix of proprietary and non-proprietary software. Even as I type this comment and enter the catch phrase code above for the antispam. Notice that the audio link points to an mp3 audio format.
There's a free alternative of flash!
For everyone, who doesn't like to use the Adobe Flash Player, there is a free alternative called gnash.
Look here: http://www.gnu.org/software/gnash/

Linking is still trivial
While I would prefer more free approaches which I endorsed later in the message, this simple thing would be a major usability improvement already, and supportive of free software (since flv can be played with many free players quite well, even if flash itself can't).
Followup
#include <apology.h>
That's Mikko.
Flash inna page
I used the link you provided to download the movie, I will watch it later when I'm on the train and therefore OFFLINE.
Flash File
Flash indeed
That being said, reading the page source yielded me the correct guess that I want to wget http://www.linux-magazine.c...2808190b9ed05e9f97b0c17490.flv and play that in the video player of my choice. This should be made somewhat easier, though (never mind that the format is... nasty, but at least it's playable), and I do hope the magazine will consider offering <video> with Theora once the next Firefox release gets its wings with integrated support. (One can of course still support other means of playing the same content, even sticking to the old means as an alternative, or, say, the Cortado Java player as Wikimedia does.)
Video?
