Missoula BarCamp 2008

What is BarCamp? Fun. Here, read a wiki if you have more questions:

I'll certainly be attending the next one when it happens (no clue on any of the specifics).

I got to see an XO laptop, you know one of those OLPC things. We talked a bit about fostering Missoula as a Tech Mecca and how to get non-profits, artists and geeks together to make Missoula better =]


OS Virtualization vs. Hardware Virtualization

Presentation PDFSlides PDFI'm all done with making the slides for my presentation on OS Virtualization vs. Hardware Virtualization for the Linuxfest Northwest 2008 conference.

Check out photos in the photo gallery. Thanks goes to Warren for letting me borrow his camera. All photos are licensed under a Creative Commons license so do with them what you will.

Update: Ok, here's the video of my presentation.

Creating an OpenVZ OS Template for Fedora 9 Preview

|

I decide to create an OpenVZ OS Template for Fedora 9 Preview. I hope to use it at the Linuxfest Northwest 2008. Creating an OS Template wasn't too hard. Actually, I created two OS Templates. One was a "minimal" and the other was a "withGUI". The "withGUI" includes KDE, GNOME, XFCE, all of the desktop apps like OpenOffice.org, GIMP, Inkscape, etc. Creating an OS Template that includes one or more desktop environments can be tricky. Admittedly, not very many people would want to use the Fedora 9 Preview after the official release comes out but these instructions should also apply to the final release if you replace the Preview DVD .iso image with the final release .iso. Read the full article for all of the details.


Review: Fedora 9 Preview

|

Boot SplashBoot SplashYesterday the Fedora Project released a "Preview" of Fedora 9. Today Ubuntu released a "Release Candidate" for 8.04 "Hardy Heron" and the openSUSE team released openSUSE 11.0 Beta 1. Since my preferred Linux distribution for the desktop is Fedora, I've been keeping up with all of the test releases. What follows is some commentary about my experiences with the Fedora 9 Preview including an image gallery. I'd like to encourage MontanaLinux users of other distros to write up their experiences with their preferred distributions.

Triumph of the Nerds

If you haven't seen the Triumph of the Nerds series from PBS' Robert X. Cringely, check it out! It was made in 1996... but it is still fascinating for anyone who either lived through it or is interested in computer history.


Part 1

Part 2 and 3 are in the full article.

Linuxfest Northwest 2008 Prelude

| | | |

The Linuxfest Northwest 2008 show is quickly approaching - April 26 & 27 in Bellingham, Washington. It happens to be the closest Linux show to Montana that I'm aware of. Last year Warren, Donnie, Ken and I went. It was a blast. Check out my report from last year if you missed it.

Anyhoo... several of us are going and I've even signed up for a presentation entitled OS Virtualization vs. Hardware Virtualization. I haven't put together the presentation yet but I have done about a half dozen related presentations over the last two years. I think with this one though, I'm going to concentrate less on specific products and more on how OS Virtualization has been making its way into the mainline Linux kernel (called CGroups or control groups).

If anyone is interested in attending the conference, please let me know ASAP. We currently have one vehicle going and one room... but we could easily expand that if need be.

Warren and I have attended three different Linux conferences in the past: Linux World Conference and Expo (once last year), Colorado Linux User Expo (twice back in the 90s - now defunct), and the Linuxfest Northwest (last year). Of the three LFNW, is the only completely free one and as such it has the strongest community feel to it. The schedule has been finalized... so check it out to see just how many things interest you... and don't forget about the exhibits either. There is a LOT there!


A need for a good mail server.

| |

I have been asked to show my supervisor what a Linux mail server would look / run like. He doesn't want to spend the money to buy Exchange or the massive rebuild of our network to get Exchange working. Here is what he is looking for:

1) global address book
2) easy user management
3) imap accounts
4) easy backup of all accounts, settings, and boxes

If anyone has a good site for a howto or a recommendation for a mail system that would be great. This is a bit over my head so I hope that some one around here can point me in the right direction.

Thanks


Some SSH & RSYNC help

| |

Hey everyone,

I am in need of a little help or a point in the right direction with some SSH & RSYNC stuff I'm trying.

Using CentOS 5 I am trying to automate some rsync tasks through ssh. I have CentOS5 on the destination too. I have a DSA and RSA key generated and scp'd onto the destination server. Essentially I am trying to do a host authentication to get around the password. The destination server is a production system so I can't lax much on the security or this would be much easier.

I have been trying to use some instruction from the rsync site as well as linuxquestions but I'm not making any real headway. The usernames are different for the source and destination systems but that shouldn't really matter for RSA/DSA authentication, should it?

Any help or refernces you could give me would be hot!

On another note, eventually I'll get to one of the LUG meetings. At least this month I made it to MSO but forgot my directions to Sean Kelly's. 8^p

BozemanLUG March Meeting Canceled

My wife is sick and will probably be hospitalized for a few days... so I won't be able to make the meeting tonight... so it has to be canceled. Sorry about the last minute notice but it is the best I could do. See you next month.


a bit of personal news...

| |

Well most of you didn't know but I have a wonderful family. A beautiful and wonderful wife and a very smart (to smart for my own good) son. I also have another one on the way. My wife is 7 months along and every thing has been going well until today.

Today we found out that she has gestational diabetes. Now this isn't that bad of news but she was at a elevated risk to start with so this just adds one more thing to the table. We will be finding out more tomorrow.

Here's to wishful thinking!!!
