I threw together a quick screencast that shows the recently released Pear OS Linux 3.0 "Panther" in action. Pear OS Linux is stylistically patterned after (some would say ripped off from) Mac OS X. It is my understanding that this is based on a customized GNOME 3.2 that shows yet again, just how malleable GNOME 3 can be with some effort.
Please excuse the SPICE connection glitches witnessed in the video. I generally don't run into issues with SPICE but this setup was a bit different with the visual affects that are turned on by default in Pear OS.

If you didn't notice, today is Fedora 16 release day. Yeah! I've been using Fedora 16 for a while now preping my MontanaLinux remix. I made a 41 minute screencast that does two things: 1) Showcases the desktop environments available in Fedora as melded together in the MontanaLinux LiveDVD remix, and 2) Shows using KVM and virt-manager some.
Please pardon my voice and occasionally sniffing... an allergy is bugging me.
Recently the Linux Foundation held LinuxCon Europe 2011 in Prague, Czech Republic. Part of it was the Embedded Linux Conference Europe held on October 26-28th, 2011.
The folks over at Free Electrons have done a quick job of making the videos from the Embedded Linux Conference Europe 2011 conference available... and in webm format too. Below I provide my two favorites.
I'm not much of a fan of Jim Kramer... but here's the video.
Flash is the best I could do. Sorry for the small size and internal branding/ads.
The KVM Forum 2011 was held at the Hyatt Regency in Vancouver, Canada on August 15-16. It was co-located with LinuxCon North America 2011.
LinuxCon and the KVM Forum were both sponsored by The Linux Foundation who recorded a large number of videos from both events. Unfortunately, The Linux Foundation had few security breaches to deal with on their kernel.org and linux.com domains which (I'm guessing) has greatly delayed them doing post-production work on the recordings and posting them publicly.
I found that Red Hat had recently posted a handful of the KVM Forum videos to YouTube but since they were only available in the flv and mp4 formats, I decided to re-encode them and post them to archive.org as webm (a free, open source, non-patent encumbered video format). I think archive.org is really a better place for them. Red Hat released them under a Creative Commons, Attribution - No Derivative Works 3.0 License. I have not altered the videos in any way other than re-encoding them to webm in a smaller resolution (624x352) and bitrate (664Kbit) making them one half to one third of the original filesize yet maintaining reasonable quality. Modern Firefox, Google Chrome, and Opera browsers can play webm as can stand-alone players like VLC, Totem, and mplayer.
They are all highly technical presentations for those interested in the nitty-gritty details of the Linux KVM virtualization Hypervisor. I have embedded the first, short keynote video below and given download URLs for the rest. Thanks to Red Hat for posting them!
One thing to note is that the camera / recording is statically positioned and does not show the presenter slides so I have also included the links to the slide decks in PDF format. For a better understanding, you are strongly encouraged to look at the slides while watching the videos. Also be warned that some presenters may occasionally use curse words.
Here's a zip file containing all slide decks in PDF format for all of the presentations.

Red Hat produced a video entitled Default to Open: The History of Open Source and Red Hat. Since it is about history, it has a number of older clips... bits and pieces I've seen before but quite a bit of new stuff too. Enjoy it embedded in webm format or use the link below to download it for local playback.

The Linux Foundation has put together a 20th Anniversary of Linux Gallery with a timeline and a lot of donated items from various companies and members of the Linux community. As luck would have it, I ripped this from youtube so I could repost it in webm format and noticed that in the original the metadata for the audio stream said -
creation_time : 1970-01-01 00:00:00. While that isn't quite true for Linux, which was started in 1991, it is basically the Epoch time considered to be the start of the UNIX universe. :)

Greg and Linus sat down for an open discussion about Linux and its 20th anniversary. They even take questions from the audience. This is from the LinuxCon Japan 2011 held in early June. They had a very similar discussion in August at LinuxCon North America but the video for that hasn't been released yet. Having seen both, I think this first one actually covers more stuff. Unfortunately the introducer takes a few minutes before we get to see Linus and Greg. In webm format.

Jon Corbet did another of his Linux Kernel talks at the LinuxCon Japan 2011 in early June. This is his Linux 20th Anniversary edition where he goes into a lot of the history of Linux so this talk is a bit different than his previous ones. Here it is in webm format.
