Andrea Limbago is interviewed by the CUBE at the Grace Hoper Celebration 2016 conference. She covers a number of interesting topics and I thought it was worth sharing. Enjoy!
On July 5th, 2016 Michael Biebl spoke at DebConf16 on systemd in Debian. This was an update to the talk last year. Enjoy!
As you may know, I've been remixing Fedora for several years for my own personal use... called MontanaLinux. I've also been remixing CentOS and Scientific Linux and thought I'd write a little bit about it.
The main reason I created the EL7 remixes is because I have a few older HP Proliant servers at work that have the CCISS Raid Controller and Red Hat dropped support for those in RHEL 7. Also, I originally included both GNOME and KDE as part of it but have since decided to make it leaner by switching to XFCE 4.12 that is available in EPEL... and of course it includes all of the available updates as of build time.
I make two flavors:
- Minimal - Just the basic XFCE with no desktop applications. This is pretty close to the CentOS minimal install except with X11 and bare bones XFCE. It weights in under 550MB.
- Full - XFCE with Firefox, LibreOffice, GIMP, Inkscape and a handful of useful tools like gParted, nwipe, rdiff-backup, etc. This weights in under 900MB.
Here are two short screencasts in webm (vp9/opus) format. The first shows the minimal install and the second one shows the full. While I'm not trying to provide a primer of the Anaconda installer, I do rush through it both times and show you post install first boot.

MontanaLinux-CentOS-7-Full-20160617.webm (5 minutes, 4.4 MB)
If anyone is interested in downloading my remix or building it themselves just email me and I'll be happy to provide the needed details. Luckily livecd-tools with livecd-creator makes it not only possible to make your own spin / remix... but fairly easy if you aren't scared of some command line. Enjoy!
Rob Potter brought the following video to my attention when he posted a link on the BozemanLUG mailing list. I converted the original .mp4 to a .webm. Enjoy.
Just got back from LFNW this morning. Gary, Rob and I went. This year they were able to capture screencasts from all of the presentations. Here's one I enjoyed attending:
A few of us were talking about VDI and KVM in IRC and our buddy kaptk2 told me that nested KVM was working pretty well these days... since Fedora 19 he said. I had not tried it yet so I thought I'd give it a try. It worked so well that I thought I'd make a screencast showing it off. The original recording size was 1920x1080 (plus titlebar) and I scaled it down to 1280x734... so full-screen it for a better view beyond the embedded 824x473 video. Oh, and yes SELinux is enabled and in enforcing mode everywhere. Umm, and NO, this is NOT an April fools joke!
There is a tiny bit of work to do to get it going but not much. Add a kernel boot parameter and configure the CPU details for the VM. For more info, see this:

A user with the IRC nick of CoffeeMan wanted to know how Fedora 23 and Korora 23 (Cinnamon edition) compared for resource usage because he was seeing performance differences between the two. There shouldn't really be much in the way of differnces other than branding and themes... so I created two KVM VMs and installed them both side-by-side. While I realize that running two VMs at the same time isn't really that bright when it comes to getting accurate performance metrics, it at least gives one an idea how of they compare... and things like the number of processes, CPU usage, RAM used, disk used, etc... shouldn't really vary that much.
While it is a fairly boring, not-much-action video, at least it is small. 28+ minutes at about 16.4 MB. It is 200Kbit (variable bit-rate) with no audio with a resolution of 1280x491 at 25FPS. Not too bad. I have made the default size in the browser be 824x316 so go full screen for a much better view.

The folks over at AmeriDroid (an American retailer of the South Korean ODROID SBC/SoC products) posted a video showing the unboxing of the C.H.I.P. mini-Linux computer. I wasn't even aware they were shipping yet. Enjoy!
