Videos: LFNW2012 Krita - Digital Graphics for Real Artists

Oscar Baechler's introduction to Calligra Krita

As you may be able to make out from the poster image, Oscar is running Krita on Microsoft Windows 7. He wanted to show the new 2.4 release and had trouble getting it for his preferred Linux distro and had to settle due to time constraints.

While Oscar is fairly new to Krita, he is a very skilled and experienced digital artist and didn't take long to adapt to it (1 week). With his Wacom tablet, he makes it look easy. Room conditions and video resolution / quality make it hard to see some finer details so make sure to have your own copy of Krita active so you can play with it as you watch, pause, watch this video.

Video: Opencast Matterhorn

| | |

At Montana State University - Bozeman, they use Camtasia Relay for lecture capture and distribution. I wasn't even aware that there was an open source alternative until I saw an "Ask Slashdot" type article where someone asked about lecture capture software... but yes indeed there is the Opencast Community / Projects and the system they have produced, Matterhorn. Check out the embedded video below which is an introduction. As far as I can tell, it (only) offers Flash-based video but I'm relatively new to it and haven't gotten all the details yet. So far as its capabilities and features go, it seems quite impressive.

Screencast: Pear OS Linux 3.0 "Panther" for Mac OS X fans

| |

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.

Screencast: History and differences of Xen and KVM

| | | | | |

I threw together a quick screencast for Dann from the Linux Link Tech Show explaining the history of and differences between Xen and KVM. Feedback is encouraged because I'm sure I have some mistakes in there.

Screencast: MontanaLinux Fedora 16 remix in KVM

| | | | |

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.

Videos: Embedded Linux Conference Europe 2011

| |

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.

Videos: KVM Forum 2011 Presentations

| | | | | | |

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 and 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 as webm (a free, open source, non-patent encumbered video format). I think 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.
