Linux Weekly News had a write-up in their Weekly Edition last week... of Lennart Poettering's talk (Containers with systemd) at LinuxCon Japan 2015. That article should be available freely later this week... but I found a recording of what appears to be the same talk at a different event from April 2015. Here are the slides. Enjoy!

Here's some documentation on that stuff if you are looking for it.
Somehow I missed this when it was first posted (Feb. 24th, 2015) from the Collaboration Summit 2015... but here it is... Jon Corbet's most recent Kernel Report. Enjoy!
LinuxCon Japan is happening this week so hopefully an updated report soon?
Checkpoint and Restore In Userspace is a project I'm very interested in as it is associated with OpenVZ and will be used in the upcoming EL7-based OpenVZ kernel branch... which was recently released in beta. The FLOSS Weekly folks have two developers on from the project. Enjoy!
BTW, Kir gave me (and Donnie) a brand spanking new CRIU tee-shirt at LFNW. Thanks Kir!
Must get moose and squirrel!
Here is a video I've been waiting for by Jike Song from Intel. The KVM Forum 2014 was held in conjunction with the recent LinuxCon Europe and someone (from the Linux Foundation or the KVM Forum) has been processing and posting presentation videos to YouTube in a staggered fashion. About 13 hours ago this video appeared. When I noticed the topic on the KVM Forum schedule (along with the slide deck [PDF]) a week or two before the event, I was really looking forward to learning more.
The current implementation, so far as basic features go, seems to be fairly complete but it is currently targeted specifically at the Intel Haswell architecture using the i915 video driver. The presenter says that the approach taken should be adaptable to other GPU architectures beyond Intel. Their initial goal is to get the code released (it is under a dual GPL/MIT license) and to work with the KVM development community to get it upstreamed and part of KVM proper... and to work on more advanced feature implementation. As it stands now the basic features are present: hardware assisted GPU functionality for VMs in a shared fashion that offers 80-90% of native speed. Near the end of the presentation is a demo video that shows two Linux KVM VMs each running GPU intensive software (one game, one benchmark). As I understand it, when a GPU-driven application is displayed it is full-screen and there isn't currently a windowed mode to show more than one VM at a time. I do wonder how well 3D accelerated graphics would display over a remoting protocol like SPICE? Enjoy!
I found the link to this video (Getting Ready for systemd) on the systemd documentation page. It is a Red Hat "Customer Portal Exclusive" and "Not for Distribution" but it is ok for me to provide a picture that links to it... that looks like a video-ready-to-play. :) Enjoy.
There has been so much negative stuff about systemd on teh Interwebs lately. It is so sad. Quite a few distros picked systemd because they liked a lot of the features it has. Why do the people who like systemd actually like it? Sure, if you look hard enough, you can find those answers... but I remembered a video where the man himself explains it.
The only problem with the original video on YouTube is that the volume is sort of low so you have to crank it up... and then there is coughing that blows your eardrums... so I took the time to edit out the coughing. The A/V sync isn't great and the sound leaves a bit to be desired... but it is still worthwhile viewing for anyone who wants to better understand why systemd. Enjoy!
If you want the coughing, you can find the original here.
Here's the Linux Kernel Panel from a couple of days ago... at LinuxCon Chicago 2014
It was re-encoded in webm format with vp9 / opus and is very low bandwidth... 200kbit video and 96kbit audio. The source material wasn't HD so it really isn't a good example of what vp9/opus can do but it ain't bad. Enjoy.
I ran across this video recently of Richard Stallman giving a TedX talk on our favorite subject. To spice things up a bit I took the original HD version I had (in ogg format) and re-encoded it with ffmpeg 2.3.2 running on Fedora 21 pre-alpha. I've been re-encoding everything to webm for several years now but finally I can do the newer flavor of webm that uses VP9 as the video codec and OPUS as the audio codec. Oddly on my Fedora 20 desktop none of my standalone media players will play the file. Some will play just the audio, others will play just the video. On Fedora 21 the players do a better job.
How can you view it? Well, vp9/opus in a webm container have been supported by both Firefox and Google Chrome for several releases now... so enjoy it in your web browser. You are using one of those, right? I prefer Firefox because I like freedom rather than an advertising company trying to make products that help themselves out. Enjoy!
Linux.conf.au 2014 just ended on Friday and they streamed most of the presentations live and have also posted the recordings. Here are three that I found interesting.

LinuxCon 2013 Europe was this week... and videos from it have started being published. Here's a video with our favorite Linux leader about the future of the Linux kernel. Enjoy!
Oh, and here is the Kernel Developer Panel
