Git - Revision Control Perfected

By Henry Van Styn 

In 2005, after just two weeks, Linus Torvalds completed the first version of Git, an open-source version control system. Unlike typical centralized systems, Git is based on a distributed model. It is extremely flexible and guarantees data integrity while being powerful, fast and efficient. more>>

Kinect

Kinect with Linux

By Rick Rogers 

The Minority Report has been in rotation on cable lately, and you've probably seen the futuristic vision of Tom Cruise standing in front of a large screen, manipulating information with waves of his hands. That vision is a bit closer to reality, thanks in part to the economies of scale of the game industry. more>>

How-To: Release Stuck NFS Mounts without a Reboot

By Igor Ljubuncic 

Computing environments may revolve around heavy usage of NFS infrastructure. Network areas are hosted and provided by storage file servers, with compute servers mounting the exported areas into their directory tree. Periodically, the mounts expire when not in use and are removed from the directory tree on local machines. more>>

DrupalCon London

DrupalCon London is Around the Corner

By Katherine Druckman 

Many of you know what a huge Drupal fan I am, and while I am a bit heartbroken that I will not attend the upcoming DrupalCon London, happening August 22-26 in Croydon, I'd like to give the rest of you the skinny on DrupalCon so you can all go have fun without me.  To that end, I got a few tidbits from Robert Castelo, one of DrupalCon's organizers. more>>

Creating a Centralized Syslog Server

By Jayson Broughton 

A centralized syslog server was one of the first true SysAdmin tasks that I was given as a Linux Administrator way back in 1997. My boss at the time wanted to pull in log files from various appliances and have me use regexp to search them for certain key words. At the time Linux was still in its infancy, and I had just been dabbling with it in my free time. more>>

Database

Moving Databases

By Shawn Powers 

I recently moved my personal website from GoDaddy to my home server. I have a business connection at my house, and my site gets little enough traffic that hosting at home on my static IP makes sense. Moving the files wasn't really difficult, I FTP'd them down from the old server, and SFTP'd them up to the new server. Moving the database was a bit more challenging, however. more>>

What Color is Your Car?

By Shawn Powers 

Geeks like their soda Mountain Dewey, their coffee strong, and their source open. But what I'm REALLY curious about is what color car we drive. You know, for science. :)

Red Orange Yellow Green Blue Indigo Violet Silver Gold White (possibly not a color) Black (possibly not a color) Grey (possibly not a color) Clear (I'm Wonder Woman, or possibly have no car)

Please select the color of your car. If you have two different color cars, or a car that is multi-colored -- pick a color you feel speaks to your inner geekness the most.  (If your color isn't listed, pick the closest. THERE IS NO "OTHER")

UPDATE: I added an option for those without cars. Because I give and give and give. ;o)

Pint-Size PPA Primer

By Shawn Powers 

Package management in Linux is great, but unfortunately, it comes with a few cons. Granted, most distributions keep all your software, not just system software like Apple and Microsoft, updated. The downside is that software packages aren't always the latest versions. Whatever is in the repository is what you get. more>>

Printing in Scribus

By Bruce Byfield 

Scribus is designed for quality printing. Unlike a word processor, its output is not meant simply to be good enough for practical use, but to be fine-tuned until it is as close as possible to what you want. For this reason, printing is considerably more complicated in Scribus than in the office applications with which you may be familiar. more>>

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
