I can do many things with the greatest of ease on the Linux desktop. But, as I discovered while doing my community Linux overview, recording a Linux desktop video isn't one of them. Oh, boy, is it ever not one of them.

When you're talking Linux, three big names always pop up: Canonical's Ubuntu, Novell's openSUSE and Red Hat's Fedora. Ubuntu has ridden a groundswell of both consumer and commercial support to its current ranking as the most popular Linux distribution. OpenSUSE, with its business underpinnings, has always been popular in Europe and has been making inroads in the U.S. And it is largely thanks to Fedora that Red Hat has become the biggest Linux company with a major role in community 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.

DATELINE: WindowsWorld 2008: Microsoft CEO and President, Steve Ballmer was happy as a clam today at his WindowsWorld keynote in San Francisco's Gates Center. "Nothing can make me happier to tell you that, Larry Page CEO of Google," a niche AOL search engine, "has agreed to run their search engine on Windows Server 2004."

Perhaps your company's outsourcing efforts would go more smoothly if you picked up a few of these effective programming tools and methodologies from open-source developers.

Does anyone really know what will be better in Windows 7? I don't and I follow Windows almost as closely as I do Linux. With Linux, on the other hand, we know exactly what we're getting well in advance of its arrival. In this latest Linux kernel, I see several outstanding new features that have been coming down the road for some time.

Quiz time. Get out your No. 2 computers and answer the following question: For the fastest and most reliable high-end computing for your enterprise, will your operating system be 1) Linux, 2) Solaris, 3) OpenVMS or 4) Windows?

It's the afternoon of September 30th and for reasons beyond my understanding the NYSE (New York Stock Exchange) is up more than 3.5 percent after yesterday's financial fiasco. Hello, Wall Street, what part of "No one has a new bailout deal; the House hated the old deal, and it's the week of Rosh Hashanah so it won't be a full week at Congress anyway" do you not understand? Even if you believe the bailout will magically work wonders for the economy -- I don't -- it's not going to happen this week.

One of the pleasures of Linux is that you can try out different distributions to see which one works best for you. You like Ubuntu, but you want to fine tune the desktop engine? OK, try Kubuntu with its KDE desktop then. Some worthwhile distributions, however, don't get as much attention as they deserve. So, here's my list of five great distributions that you might want to try.

Even before Red Hat bought the virtualization company Qumranet, with its Linux KVM (Kernel Virtual Machine) platform, Red Hat had made it clear that it was moving into virtualization in a big way. At its annual Red Hat Summit in June, the Linux powerhouse announced that it would be deploying its Embedded Linux Hypervisor, oVirt, which is based on KVM in its server line. This lightweight, embeddable hypervisor currently enables users to run run Red Hat Enterprise Linux and Windows VMs on Linux.

Once upon a time at a NASA space flight center a long way away, I was an e-mail administrator. At the time, the 1980s, e-mail was still chaotic. The RFC 822 standard was only beginning to bring rhyme and reason to e-mail. One of RFC 822's competitors, the Common Messaging Calls (CMC) X.400 standard, wasn't making much progress, but then Microsoft adopted it in 1992, added the concepts of folders to it, and re-named the result Mail Application Programming Interface (MAPI). And, ever since, the e-mail world can broadly be divided into two camps: the RFC 822 Internet compliant e-mail group and the MAPI-compliant Microsoft Outlook/Exchange pack.
