Compiz Fusion

Compiz Fusion

In case you haven’t yet heard of Compiz Fusion, built from the Beryl composite window manager for X windows, hurry on over to their site and check it out, the effects are almost good enough to rival Mac OS X in my opinion.

Compiz Fusion aims to provide an easy and fun-to-use windowed environment, allowing use of the graphics hardware to render each individual window and the entire screen, to provide some impressive effects, speed and usefulness.

Open Source Community

Open Source Community

Now that I have my blog up and running and have began posting regularly I would like to take a minute and thank everyone for their contributions to the open source community. I would especially like to point out Falko Timme of ISPConfig and HowtoForge, his contributions are obviously devout and have especially been helpful to me. Thanks Falko!

I would also like to recognize Vasily and everyone at the OpenVZ project, I feel that they are leading the way in the open source world with Linux virtualization software. In addition, all of you kernel hackers and other Linux gurus out there also deserve to be recognized for your hard work and efforts. Thank you for staying the course and working on something that you believe in.

Regards,

Matt

3ware Escalade Linux Management Software

3ware Escalade Linux Management Software

I was having some problems the other day with a 3ware Escalade 8506-8 RAID controller, this problem led me to tw_cli, a program designed to interface on the linux command prompt with the 3ware RAID controller in my remote linux machines. I even found a neat script that someone wrote to help notify you of any drive or RAID problems as they occur on your system.

Follow the directions here:

I added the following to /etc/apt/sources.list:

deb http://ftp.debian-unofficial.org/debian sarge restricted

Then I ran:

apt-get update
apt-get install 3ware-cli-binary
man tw_cli

OpenVZ Cluster

OpenVZ Cluster

As we get further into developing the Piranha Method site, we plan to also work on deploying a site for Hostmaster Flex to offer our hosting services for the OpenVZ cluster that we have set up.

The OpenVZ project is an open source community project supported by Parallels and is intended to provide access to the code and ultimately for the open source community to test, develop and further the OS virtualization effort. – OpenVZ

We are currently running a Linux High-Availability hosting cluster built on a custom OpenVZ kernel for server virtualization on the Debian etch Linux distribution along with RAID-1 server using DRBD. In the future we plan to add more servers to the cluster and load balance the cluster load between them, we are currently planning to deploy the necessary fibre channel gigabit technology for each server in order for this to be feasible.

We have been running our OpenVZ cluster for about two years now in a production environment and have only had some minor problems with our 3ware Escalade RAID controllers Linux drivers. This was because we were previously running our cluster on the CentOS 4.4 (RedHat) distribution and apparently our hardware combination, along with the use of OpenVZ technology uncovered a bug in the 3ware Linux drivers.

Overall, I have had nothing but a great experience with OpenVZ, my only wish  (if someone is so inspired) would be a nice web-based GUI for virtual server management and migration. I have found a few OpenVZ managers out there, but none that seem complete or even that seem to function correctly.

WordPress + K2 + Piranha Method = <3

WordPress + K2 + Piranha Method = <3

I have just finished deploying WordPress using the K2 template as the new framework behind the Piranha Method site, I will be adding in some other neat plug ins and customizing some of the PHP to meet my needs . I find WordPress much easier to use and work with than anything else out there, not to mention that the code it creates is clean valid markup.

Keep an eye on this blog as I am going to be posting often to help boost site traffic as well as give me a good place to log my work notes.
