It's doubtful that very many users enjoy reboots. Although system uptime is often worn like a badge of honor — as though power-cycling were some form of humiliating defeat — the majority of us can probably agree that having to restart is a pain, if only for the lost time involved. It almost seems as though the annoyance grows exponentially the more frequent they come.

According to Wikipedia, "In computing, regular expressions provide a concise and flexible means for identifying strings of text of interest, such as particular characters, words, or patterns of characters". If you even dabble in open source, shell scripts, and writing code, you are likely at least somewhat aware of regular expressions. Some people are even really good at using regular expressions, but this method can be a struggle for others. O'Reilly's Cookbook series offers over 100 "recipes" using regular expressions to solve common tasks. The question is, will this cookbook help you whip up the dish you need to serve?

Back in April we reviewed the ASRock X58 SuperComputer and found it to be a phenomenal motherboard for use with Intel Core i7 processors. While ASRock is regarded as being a budget manufacturer, this affordable Intel X58 motherboard could overclock quite far, ran well with Linux, and offered a great set of features. While that was a very nice Intel product, how are ASRock's current offerings on the AMD side? In this review we have our hands on the ASRock M3A780GXH/128M to see how well this AM3 Socket motherboard with a 780G + SB710 Chipset performs under Linux.

This article will show you how to set up openerp-server 5.0.0-3-1 + openerp-client 5.0.0-3-1 + openerp-web 5.0.1 on Ubuntu Server 9.04. Open ERP (formerly named Tiny ERP) is the leader open-source ERP/CRM system written mostly in Python and initiated in Belgium. It offers a three-tier web architecture, ease of use and flexibility.

Sugar Labs, responsible for building the low-cost device's OS, has released it online for loading onto any USB flash drive greater than 1Gb, and will allow it to be used on "any PC or netbook", it said in an announcement. Called "Sugar on a Stick v1", Sugar Labs hopes it will help spread the use of the OS in classrooms, without the need for the OLPC device. An IDC analyst said earlier this year, the OS would be one of the OLPC's more attractive aspects vendors would be interested in copying for the netbook market.

Even if you don’t want to replicate the mac, or if you think compiz is more useless than it is functional (how dare you!?), you might still be interested in replacing one of the two Gnome taskbars with a dock. Here is my dating history with the docks of Linux land.

The Sun-sponsored VirtualBox project has released a beta 3.0 version of its free, x86-oriented virtualization software. The Linux-compatible xVM VirtualBox 3.0 adds support for guest Symmetric Multiprocessing (SMP) with up to 32 virtual CPUs, as well as support for version 2.0 of the OpenGL graphics acceleration standard, among other features. Targeted at server, desktop, and embedded platforms based on x86, VirtualBox lets users run their favorite software, Sun says, while enabling developers convenience when building, testing, and running "cross-platform, multi-tier applications." It does this by enabling development and target systems to share a single physical host. Supported target "platforms" include Linux, OpenSolaris, Solaris, Windows, and Mac OS X.

Time for another Kubuntu Tutorials Day. Learn about KDE and Kubuntu development in a helpful atmosphere next Monday from 19:00UTC in the #kubuntu-devel IRC freenode channel. We have a lineup of exciting speakers on a range of topics. Read on for the timetable

Stealth has an advantage of gaining access undetected. A stealth firewall provides a way to gain access to filtering Internet traffic from a position of stealth. A bridge provides stealth because it does not use an IP Address to function but rather operates at the Layer 2 of the OSI model meaning that without an IP Address the firewall is unaccessible and hidden from all would be attackers. This course will show you how to build a stealth firewall that you can drop in anywhere on your network to protect some aspect of the network.

A Cascading Style Sheets (CSS) framework expedites and simplifies the design and development of Web pages. Moreover, a CSS framework produces more standardized results in all browsers. Here's a look at two CSS frameworks, each with a unique philosophy.

A couple of weeks ago, I wrote an article about a digital and analog circuit simulator called ksimus. One of my readers asked what the difference was between ksimus and ktechlab so I thought I'd take a look at ktechlab.

If you find your computing experience somewhat cold, give these heated peripherals a shot!

Low-cost, energy-efficient Userful Multiplier desktops running on Novell’s SUSE Linux Enterprise Desktop have transformed the way SASSA officials capture and process social grant applications in rural South Africa.

As a consultant, I am often faced with an unfamiliar Linux system (usually RHEL). I always find it useful to understand which files that shipped with rpm packages have been modified, since it's usually a good indicator of what customizations have been performed on the system.

Power and space saving computers are in, and Shuttle has a winner with the XS29F. This little gem really skimps on the power consumption to the tune of around 20-25 watts on average. That's less than half of that 60-watt light bulb shining down on you right now. For the Do It Yourselfer (DIYer) on a budget this box makes a lot of sense. The size is right, too, as the unit measures a skimpy three inches tall and a little over seven inches wide. Two doors on the front reveal the DVD drive, two USB ports and the typical audio in / out jacks. A power brick similar to one you would use with a notebook computer helps offload some of the electronics and heat generation outside of the box.

Take a Fedora Live CD for a spin and tell me how you like it. Ok, so we all know that I've been giving Fedora a bit of a black eye lately with my BaitNSwitch and Is Fedora Still Relevant posts so I've decided to give them some positive press and enter their Spins Zone. Spins are live Fedora CD images designed with a specific purpose or function in mind.

MediaMosa, a video management and distribution platform, which has been developed in the Netherlands to deliver video content to the Dutch educational sector, is now open source. In their announcement of the release, the developers, SURFnet, a provider of IT services to education and Stichting Kennisnet, the public IT support organisation of the Dutch educational sector, said they hoped that open sourcing the application would allow other developers worldwide to work with the software.

A collective "aargh" resonated throughout the Linux blogosphere in response to Nvidia's dissing of Android in favor of Windows CE for running smartbooks. It really should come as no surprise, suggests blogger Gerhard Mack: "[Nvidia] is a company that got dragged kicking and screaming into the open source world, and they really don't want to be here."

As I described in an earlier article, the first two years of the OLPC deployment in Uruguay "have been characterized by implementation and incubation. The laptops have been deployed to schools, manuals have been created, tech savvy volunteer groups have been formed, wireless internet connections have been established, teachers have slowly learned how to implement the laptops into their curricula and classrooms, and, as Rezwan has covered previously, a community of open source programmers has developed educational applications for the laptops."
