Getting ready for LinuxWorld Expo 2007

|

Next Saturday (August 4th), Warren and I head off to San Francisco for the LinuxWorld Expo 2007. We will be helping to staff the OpenVZ booth at the .org Pavilion.

This opportunity kind of fell unexpectedly into my lap when Kir posted an announcement that they were looking for a few community members to help staff the booth given the fact that they had seven exhibit passes and would only be sending two of the OpenVZ developers over from Russia, "as to not stall development."

I've been increasing my OpenVZ knowledge and plan to practice giving demos with Warren a bit on Sunday and Monday. I've been using OpenVZ on a daily basis for over a year now, given two public OpenVZ presentations, written several articles... so interacting with community members and promoting OpenVZ to the crowd at LinuxWorld Expo seems like a natural progression. I really look forward to meeting Kir Kolyshkin and Konstantin Khorenko from the project as well as Marc Perkel who will also be staffing the booth.


libvirt begins to add OpenVZ support

| | | |

I noticed a blog posting by Daniel Veillard on Fedora People about initial support for OpenVZ being added to libvirt. If you aren't familiar with libvirt, it is an underlying library/API that can be used by higher level tools to create, manage, and monitor virtual machines. libvirt is trying to be technology agnostic by supporting several virtualization technologies. They started off with Xen and QEMU but have since added KVM. libvirt is used by the GUI tool Virtual Machine Manager which first appeared in Fedora Core (now Fedora) but became part of Red Hat Enterprise Linux 5.

Looking at some of the postings in the libvirt mailing list archive for this month, it is mentioned that adding OpenVZ support is a bit different than previous technologies because the OpenVZ tools are already GPLed, "simple and straight forward", and than OpenVZ additions to libvirt "ends up looking very close to the original". I don't know how far away complete support for OpenVZ is in libvirt nor when it will show up in Virtual Machine Manager but I definitely look forward to it... although I doubt it would completely replace vzctl and the other OpenVZ tools for me.


My first Rocks Cluster

|

Rocks ClusterRocks ClusterI finally got Rocks Cluster installed today. I installed it on the six dual Xeon/P4 machines that Intel donated. Getting this going has taken me a lot longer than I had hoped. It wasn't the fault of the Rocks Cluster software package but the odd combination of hardware.


Screencast: Introduction to OpenVZ

| |

I learned about a handy dandy program today named recordmydesktop and the GUI for it, gtk-recordmydesktop. Seems to work pretty well. How well? So well that I actually ran out and bought a microphone so I could record the following video.

I've done a few presentations on OpenVZ and I had some slides made so... what the heck... I thought I'd slap together a presentation video.

The video is 800x600 and I didn't want to stretch the center column on the front page, so read the full story to see the included video.

Message Passing Interface

I've been mucking around in the world of distributed programming recently. In my defense, I was investigating this topic BEFORE Scott got his hands on a stack of rack mount computers from Intel. But I will admit the sight of all those idle CPU's put the angst into my code-writing fingers. So I've gone ahead and actually written a distributed application.

A little background on distributed computing. First off, we need the obligatory "Linux is awesome." There is a kernel module for Linux called MOSIX that will transparently move CPU/Memory bound applications away from the machine they were launched on, and return those processes as soon as they need to make a system call. That's awesome.


I took the plunge

|

After last night's Bozeman LUG meeting, I decided to take the plunge and install Ubuntu on my newly (more or less) built AMD dual core machine. It was really rather anti-climactic. It installed itself, everything worked, no problem. I sniffed around a little and got my printer hooked up through the network and the existing windows box. No command line, no profanity, no bloodshed. Ubuntu loaded the NVIDIA drivers with the usual disclaimer about proprietary software and put them to work. Who says that Linux isn't ready for the desktop? Now to learn about VMWare....


MythTV Demonstration at June '07 BillingsLUG

MythTV Screenshot

Thanks to everyone that showed at C4K in June for the MythTV presentation.

We successfully installed a complete digital video recorder system from scratch on a standard PC. The final product displayed its ability to watch live TV, pause and rewind live TV and record shows. The guide data is very nifty and pulled across the internet from zap2it. Which has recently announced that they will be discontinuing that service. So the MythTV developers are hard at work attempting to come up with a better (and hopefully truly open) solution.


An oldie but goodie from IBM

I wish I could identify everyone in this video. I believe each person to be an expert in a particular field. I see Penny Marshall and Muhammad Ali. Can anyone identify some of the others? IBM must have spent quite a bit of money making this commercial.


The Wizpy from TurboLinux

This isn't much different than booting from a USB key but hey, it has a screen and also functions as a multimedia device so that increases its functionality and cool factor, right?


Revolution OS - A little dated now

Wow, has it really been 6 years since we watched this movie at a BillingsLUG meeting? Well, if you haven't seen it, enjoy. I think J.T.S. Moore did a good job. Buy a copy if you want a high quality version on DVD. I did!
