A content management system is a centralized repository for your content. A Web site is a composite of decentralized fragments that are assembled on the edge, in just-in-time fashion as the content is being delivered to users. If it's not a Web site, what does a CMS do? more>>

Creating a live Linux USB stick isn't anything new. And, in fact, the ability to have persistence with a live CD/USB stick isn't terribly new. What many people might not be aware of, however, is just how easy it is to make a bootable USB stick that you can use like a regular Linux install. more>>

Razor-qt is a new desktop environment based on the QT toolkit. I installed it from the PPA and gave it a quick go. It’s early days for the project, but it might eventually become a refuge for lovers of KDE 3 in the same way that Xfce has become popular with people who want to recreate the Gnome 2.x experience. more>>

Portability is a huge advantage that Linux enjoys over most other desktop operating systems as most major distros work very well when installed to a flash drive. However, there are still machines in service that just won't play ball when it comes to USB booting. Fortunately, I found a nice little utility that can work around this problem. more>>

Perl has been around for more than 20 years. During that time, it has received its share of both praise and criticism, and lots of misconceptions surround it. Much of this stems from long-outdated notions of what Perl used to be, but have nothing to do with what Perl actually is today. more>>

I've realized I've missed out on a huge area of computational science—chemistry. Many packages exist for doing chemistry on your desktop. This article looks at a general tool called avogadro. It can do computations of energy and gradient values. Additionally, it can do analysis of molecular systems, interface to GAMESS and import and export from and to several file formats. more>>

No, it's sadly not a day for shopping. Today, some of the most visited websites are dark to raise awareness of two bills now making their way through the U.S. Congress. more>>

I'm in midtown Manhattan, connected to the Net over my hotel's slow but costly wi-fi connection. Normally when I'm traveling — at least here in the U.S. — I avoid lame hotel connections by using AT&T's cellular data system, usually through my iPhone's "personal hotspot." more>>

BeOS was a much loved and highly advanced desktop operating system that ceased active development in 2001. ZevenOS is a Ubuntu 11.10 based system (with a bit of help from Xubuntu) that attempts to recapture some of the BeOS look and feel. more>>

We've all done it. Now you can share your humorous and/or awkward blunder with the world! Watch the video below for all the details.

What may sound like a perverse concept is actually one of the many ways smartphones can change your life. If you play a musical instrument but don't happen to have perfect pitch (most of us, sadly), you can buy a tuner, pitch pipe, tuning fork or any number of other aids to keep yourself in tune. If you have a smartphone in your pocket, however, you also can simply download gStrings. more>>

I hope all my readers enjoyed the best of the holiday season. I've been busy with the predictable confusions and minor crises that attend this time of year, but I managed to find time to jot down some recommendations for my readers. Go on, you've been good, give yourself a few extra belated gifts and don't worry if your budget's busted - it's all free software, you can't beat these deals. more>>

The recently released Linux Mint 12 offers a two pronged approach to supporting those who prefer the traditional Gnome desktop. Firstly, the Mint Gnome Shell Extensions (MGSE) transform Gnome 3 into something resembling Gnome 2. Secondly it ships with Mate, the Gnome 2.0 fork project. more>>

I used to have a paperweight sitting on my desk that read something like “Robert H. Lane, appointed President of Commodore Computers....” It was the sort of thing that they gave to executives. A brass plaque of their appointment as it appeared in the Wall Street Journal or the Globe and Mail. more>>

LiMux, a project to convert local government institutions to Linux and open source software in Munich, has exceeded initial expectations. The project has done slightly better than projections of 8,500 and now boasts 9,000 Linux migrated workstations. The progress and evolution of this project that began in 2003 is well worth examination. more>>

As the year comes to a close, it is time for year-end reflections. In our case that means sharing the most popular articles of 2011. The following were viewed the most, and in some case created a lot of discussion as well.

Many Linux users who have been GNOME fans for years find themselves in a sudden quandary. GNOME 3.0 has completely abandoned the desktop experience we've come to love during the years. That's not to say change is bad, it's just that many folks (even Linus Torvalds) don't really want to change. more>>

This article is a bit different from my usual column in two ways. First, it's starting with a hardware and software combo—something I've not done before. Second, the projects are linked to each other and come recommended to me by Perth LUG member, Simon Newton. more>>

Packet capture is one of the most fundamental and powerful ways to do network analysis. You can learn virtually anything about what is going on within a network by intercepting and examining the raw data that crosses it. Modern network analysis tools are able to capture, interpret and describe this network traffic in a human-friendly manner. more>>
