Let's take a look at three projects that are aimed at showing calendar information through a Web interface: WebCalendar, VCalendar, and CaLogic. These projects run on a LAMP server and provide a Web interface to calendar events. For testing when one or more calendars are required I'll use the US Holidays and UK Holidays from the publicly available iCalendar files at icalshare.com. All installation and testing was done on a 64-bit Fedora 9 machine.

John Dragoon, Novell’s Senior Vice President and Chief Marketing Officer today announced that due to the difficult economic times, BrainShare 2009 has been cancelled. The announcement made it clear that the primary reason was that Novell’s customers “are under increasing pressure to reduce travel and other controllable expenses and are hesitant to commit to attending our BrainShare 2009 conference.”

Adobe Systems is extending on Thursday its AIR (Adobe Integrated Runtime) technology to Linux desktops. Previously available for Windows and Macintosh, AIR is Adobe's free technology that enables delivery of Web applications that also can run outside the browser; it lets Flash programs run on the desktop. The Linux version of the software can be accessed here. The company is making available version 1.5 of AIR for users of the OpenSuse 10.3, Fedora Core and Ubuntu 7.10 or higher open-source Linux distributions. AIR 1.5 also has worked on Red Hat Enterprise Linux Desktop, but the company has not tested it on this implementation of Linux.

There's a long standing argument over the differences between "open-source" software and "free" software. But, a more common error outside of software ideology circles is that you can use open-source software anyway you please. Nope. Wrong. It's never been that way. Cisco, the networking giant, should know better than this, but they've worn out the FSF's (Free Software Foundation) patience. So, Cisco is now being sued by the SFLC (Software Freedom Law Center) on behalf of the FSF for Linux and other GPL copyright violations.

Linux has a strong following among those who manage corporate servers, a loyal corps of desktop users and a small but growing base of laptop users. But it's also been a big -- if stealthy -- success as a platform for gadgets. In fact, there ought to be a Linux Gadget Hall of Fame. I'll get it started with the first group of inductees: 10 of the most important gadgets of all time, each one based on Linux.

Some of us will find some kind of alleged spare time on our hands over the next few weeks. Certainly, there’s often some kind of break from “work” over the festive season. Traditionally free software developers have used such times for long coding sessions, get-togethers and “hack-fests”. Of course we’re not all hard-core (or even soft-core) hackers so here’s a few suggestions for the rest of us who might want to try something new over Christmas.

Sun Microsystems has announced the release this morning of VirtualBox 2.1 with several enticing additions. VirtualBox 2.1 introduces support for hardware virtualization (through Intel VT and AMD's AMD-V) on Mac OS X host systems, support for 64-bit guest operating systems on 32-bit host systems, support for Intel Nehalem (Core i7) virtualization enhancements, full VMDK/VHD support, a new NAT engine, and new Host Interface Networking implementations on Linux and Windows. Perhaps though one of the most exciting changes in VirtualBox 2.1 is initial support for OpenGL acceleration on the guest operating systems.

In this article, I'm going to present a whole variety of Linux games, across a range of genres. I'm going to review several titles in detail, complete with screenshots and grades. Next, I will talk about non-native Linux games, which can still be enjoyed using certain tools and methods. We will talk about the tools and methods, too. We'll also talk about mini-games that come bundled with distributions, Flash games, online game repositories, and more. It should be interesting. If you're a gamer, spend 5-6 minutes of your time reading. I promise you, you'll like it. So, if you are new to Linux and wondering if you can enjoy games on Linux, the answer is: very much so yes. Follow me.

Movial is shipping a new version of its mobile video communications software that offers high-definition (HD) PC-to-PC, and PC-to-mobile video-conferencing. In addition to releasing Movial Communicator PC 7.2, Movial announced it has partnered with Cypriot telecom carrier Cyta to offer Communicator-based video-calling services.

Every major web browser has been updated this week, mostly to deliver security patches. It isn't every week that sees the delivery of an update for or affecting each of the major browsers. Those of us who like or need to use multiple browsers have plenty of downloading and installing to do, so thank goodness the process is largely automated.

Six-year-old BlueStar Energy Services Inc. doesn't have the kind of systems-baggage that saddles many older organizations. Still, the Chicago-based company found itself hindered by the rigidity of its core systems, which constrained its efforts to expand its customer base and offer new services. Those barriers to growth led the company to embark on a bold effort to replace the bulk of its IT infrastructure -- including voice, e-mail and financial systems -- with open-source software. The initiative has been so successful that CEO Guy Morgan attributes much of the company's recent growth to it.

What's the crowd up to these days? Solving the world's problems -- and saving corporations a lot of money in the process. A few individuals are managing to eke out some personal gain in return for their contributions, but for the most part, the crowd is beginning to look like an incredibly large, wise, cheap labor pool. Fortunately, it's also unwieldy, which may be the crowd's saving grace.

The largest trend in Solaris deployment these days is to wait for end-of-life and then replace the server with Linux, where possible. But now that OpenSolaris exists, should this trend continue? Perhaps we should look at OpenSolaris instead of Linux? Last week I took the stance that OpenSolaris could in fact replace Linux. In theory—in the future, if Sun plays its cards properly—this is possible. Asking if I’d deploy OpenSolaris at work, however, is a very different question.

For many years Spamhaus has been top dog in the anti-spam world of DNSBL (Domain Name System Block List; also known as Realtime Blackhole Lists or RBLs). But Spamhaus is no longer a 100% free service. Even small nonprofits are now expected to pay at least $250 per year for a subscription to the Spamhaus DNSBL Datafeed Service. Now a new, free alternative to Spamhaus has arrived: the Barracuda Reputation Block List (BRBL), provided by well-known, open source-based Barracuda Networks. And Barracuda CEO Dean Drako says the company has no plans to charge for the service in the future. He says that BRBL (pronounced "barbell") "does cost us a little bit of money to run, but we think that the goodwill, the reputation and the understanding that Barracuda is providing the service will do us well in the long run."

The sysrq key sits quietly at the top of your keyboard, usually sharing space with PrntScrn. sysrq is a direct hotline to the kernel and gets you out of trouble when your system is getting tangled up in itself; Juliet Kemp shows how.

Low-level optimization of performance-critical code can be a challenging task. At this point, one assumes, the potential for algorithmic improvements in the targeted code has been realized; what is left is trying to locate and address problems like cache misses, mis-predicted branches, and so on. Such problems can be impossible to find by just looking at the code; one needs support from the hardware. The good news is that contemporary hardware provides that support; most processors can collect a wide range of performance data for analysis. The bad news is that, despite the fact that processors have been able to collect that data for many years, there has never been support for this kind of performance monitoring in the mainline kernel. That situation may be about to change, but, first, the development community will have to make a choice between a venerable out-of-tree implementation and an unexpected competitor.

Novell Inc.'s openSUSE project is becoming more open, as a new release due out Thursday includes licensing changes that make it easier to redistribute the Linux operating system, as well as a build service that will encourage more contributions from open-source developers. OpenSUSE previously used a standard user license agreement and contained some proprietary software -- namely Adobe Acrobat and Sun Java -- that made it difficult to redistribute the open-source software, says Joe Brockmeier, Novell's openSUSE community manager. OpenSUSE 11.1, the release that will be announced Thursday, modifies the license to eliminate some of the legal headaches and removes the proprietary software, which now must be downloaded separately.

eRacks Open Source Systems has introduced a new desktop model that uses the recently-released Intel (News - Alert) Core i7 processor. The Core i7 processor from Intel is the first member of a new family of Nehalem processor designs and is equipped with new technologies that boost performance on demand and maximize data throughput. The Core i7 processor speeds video editing, immersive games and other popular Internet and computer activities by up to 40 percent without increasing power consumption.

Debian developer Josselin Mouette has had his privileges of posting to the announcement mailing list for developers withdrawn, following an offensive post to the list in November. Debian Project Leader Steve McIntyre told iTWire that after Mouette's "abuse of the ability to post to the d-d-a mailing list, I asked our mailing list administrators to remove that privilege for in future." Following the post on November 23, at least two Debian women developers indicated they were reconsidering their participation in GNU/Linux project.
