For those of you attending the Southern California Linux Expo (SCALE) next month in Los Angeles, Matthew Tippett and I will be hosting a talk. This talk is entitled "5 Stages of Benchmark Loss: PTS and You" and, of course, covers the Phoronix Test Suite software and its capabilities and more for autonomously testing Linux and other operating systems.

For me, the hardest part about teaching the LPI 101 course is teaching about text-stream filters. It’s not that they’re difficult to understand. It’s just that showing the examples of how they work is easy, but showing examples of how they can be used in real life is a bit more challenging. Real-life examples from the Linux admin world are fairly complex, and are beyond the level that most beginning Linux students are able to grasp. So, in most LPI books, the student will see how these utilities work, but not how to use them.

Skype, Polycom and a range of other partners are gearing up for Digium's Asterisk World conference (Jan. 20-22). But the big focus for Digium at the open source IP PBX event will likely involve updates to several new Digium initiatives. Here's an update.

Kaseya -- a fast-growing provider or remote systems management tools -- is preparing to introduce remote management software for Red Hat Enterprise Linux, Novell SUSE Linux, and other Linux distributions. Here are the details.

We sometimes find what we are looking for while searching for something completely different. This happened to me recently. I was searching for a way to fix some graphic performance issues being experienced on kubuntu, When I stumbled upon (no pun intended) a packaged named ppa-purge.

We’ve had the battle of the apps and now it’s the battle of the handset. But after all the hype, it has not been the greatest start for Google and the Nexus One phone - maybe we should be looking forward to the Nexus Two and all that might bring with it?

With a bit of a delay, Ubuntu Tweak 0.5 has been finally released. We already posted a quick what's new guide (initially, 0.5 was supposed to be released on 1th of January, so read about most of the new features there), but let's have an even quicker look at what's new:

The Ftrace tracing utility has many different features that will assist in tracking down Linux kernel problems. The previous article discussed setting up Ftrace, using the function and function graph tracers, using trace_printk(), and a simple way to stop the recording of a trace from user space. This installment will touch on how user space can interact with Ftrace, faster ways of stopping the trace, debugging a crash, and finding what kernel functions are the biggest stack hogs.

Ubuntu Customization Kit is a GUI tool that helps you customizing official Ubuntu Live CDs (including Kubuntu/Xubuntu and Edubuntu) to your needs. You can add any package to the live system, for example language packs, or applications.

Recent “zypper update” on November’s openSUSE 11.2 release brought system to the most recent status. Current 2.6.31.8-xen kernel works fine. Seems like a next generation of xenified aka Suse kernels is on the go right now. However, i believe,that vm-install on recently updated 11.2 works same way as before maintenance update. So, in meantime vm-install doesn’t inderstand either HTTP or CDROM sources attempting to create PV Guest and virsh scripting appears to be the only one option to create Xen PV Guests manageable via virt-manager. Notice, that F12 PV Guest install doesn’t require HTTP or NFS share , pygrub performs install just via F12 ISO image , like OpenSolaris PV Guests get installed as usual.

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 9.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Open Shot Video Editor Version 1.0 has released. OpenShot Video Editor is an open-source, non-linear video editor for Linux. Here is how you can actually install OpenShot 1.0 in Ubuntu.

I am proud to announce that OpenShot Video Editor 1.0 has just been released! This release is jam-packed full of new features, bug fixes, and some shiny new graphics! We hope you enjoy it!

Tips for Linux administrators entering and moving through today’s Linux admin market as traditional qualifications become less relevant and the need for real skills increases.

Ever since Oracle announced the acquisition of Sun Microsystems along with MySQL, all hell broke loose in the open source community. With EU questioning the deal, there is a war (of words) erupting inside the community with one side asking EU to block the deal or, at the very least, change the license to another open source license from GPL and the other side urging EU to allow the transaction to go through. Even though I have no love for Oracle, I think it is time to let the deal go through at least for the sake of Sun employees who are sitting there with their future unknown. At the same time, I am not unduly worried about the future of MySQL because I have complete confidence in the open source license of MySQL. Let me try to explain my position here in this post.

This article is part of the on-going 15 example series where 15 examples will be provided for a specific command or functionality. In this series, earlier we discussed about find command, crontab examples, grep command, history command, ping command, and wget examples. In this article, let us review 15 examples for Linux top command that will be helpful for both newbies and experts.

The Oregon State University Open Source Lab's data center hosts some of the Linux community's heaviest hitting projects including the Linux Master Kernel and the Linux Foundation. It is also the primary location for the Apache Software Foundation and Drupal, open source content management software. The lab, aka OSUOSL, also hosted the core infrastructure for Mozilla's Firefox project, and currently host's six of Google's servers. Despite housing such high-profile open source projects, the lab's systems administrators are actually OSU computer science students. In the following Q&A, Lance Albertson, an OSUOSL systems administrator and architect, talks about his job -- managing a data center with a staff of 18- to-21-year-olds. SearchDataCenter.com recently visited the OSUOSL data center on OSU's Corvallis, Oregon, campus and talked with Albertson about the rewards and challenges of his job.

Small business owners may have more of a need than most to be able to access their chosen suite of productivity tools from more than one computer or platform. As a business or startup owner you may have occasion to bring your work home with you, or require frequent access to your to-do lists, notes and documents on the go. Choosing primarily online tools for your productivity workflow is a great way to address the issue of source agnostic accessibility. It's also a convenient method to ensure you have a backup of your important day-to-day items and files in case a particular computer or device fails. One other not insignificant factor in selecting cloud-based tools to keep you and your business on track is cost: the online equivalents of once desktop-bound applications are often much cheaper in both raw cost and maintenance cost, as tool upgrades usually happen behind the scenes and don't require an in-house IT staff to keep up and running.

There are not a lot of free software options for mastering DVDs. One of the more complete solutions is QDVDAuthor, although it still has a number of rough spots. It’s a front-end to a collection of command-line free software tools that do each of the individual steps involved in going from a collection of digital video files, audio files, and images to a DVD with menus. As such, it’s quite complicated, and not as stable as some software. Still, it is a rewarding experience if you stick with it. Here I’m going to walk through creating a DVD for a collection of animated videos by my new favorite free-culture artist, Nina Paley (partly because the CC By-SA 3.0 license eliminates any questions about copying the material here, and partly because they’re pretty cool in themselves). Read the full tutorial at Free Software Magazine.

If you use Samba you certainly want to create shares which provide users with private shares. This tutorial will show you how to create a share that is accessible to one user to store their information.
