Is OpenSolaris in hot water?

Here’s how it works: Novell owns Unix’s IP (intellectual property). SCO sold Unix’s IP to Sun. Sun then included some Unix IP into Solaris. Finally, Sun open sourced Solaris as OpenSolaris. Sounds like trouble, doesn’t it?

While Sun’s Chief Open Source Officer Simon Phipps described the line of logic above as “sheer speculation,” others see a major potential legal problem for Sun. However, analysts, lawyers and open source leaders also agreed that it’s unlikely Novell would ever choose to make trouble for Sun. Novell, however, has not commented on its intentions despite several attempts to get the Linux company’s take on the issue.

Thomas Carey, chairman of the business practice group at the Boston-based Bromberg & Sunstein IP law firm, describes the legal details like this: “As to Sun, SCO released Sun from a confidentiality obligation with respect to SVRX (System V Release X Unix) code when its contract with Novell did not permit it to do so without Novell’s permission. SCO did not seek or obtain that permission. This proceeding does not involve Sun as a party, only SCO and Novell. As between these parties, the court views the genie (the confidential information) to be out of the bottle, and the court can’t put it back in. It can, however, hold SCO liable to Novell for breach of contract (and/or breach of fiduciary duty), and it did so and found the damages for this breach to be $2.5-million.”

What does this mean for Sun? Carey says, “In theory, Novell could sue Sun directly, but its chances of success would be slim. Furthermore, Novell is not interested in pursuing/developing SVRX, and is more interested in its reputation in the open source community. Its lawsuit against SCO was political — it got to wear the white hat. If it went after Sun because of OpenSolaris, it would wear the black hat. It is not likely to change hats now.”

How Dell is making Ubuntu more attractive

Dell was the first of the major computer manufacturers to support pre-installed Linux, but it’s not just pre-installing Linux. The Austin, Tex. company is also adding functionality to Ubuntu Linux on its desktops and laptops.

Dell began adding extra features last December when it added DVD-playback to its systems shipping with Ubuntu 7.10. Ordinary Linux can only play DVDs if they’re not burdened with DRM (Digital Rights Management) malware. By including InterVideo’s closed-source LinDVD DVD playback software users are able to legally play DRM encrypted DVD movies.

With the recent release of Dell PCs with Ubuntu 8.04, Dell has added other goodies to the basic Ubuntu Linux distribution. As John Hull, Dell’s manager of Linux engineering, describes in Dell’s Direct2Dell blog, Dell is now including “Fluendo GStreamer codices for mp3, wma (Windows Media Audio), and wmv (Windows Media Video) playback” in its latest Ubuntu-powered desktops and laptops.

The two essential Firefox extensions

Firefox 3 is good. Firefox 3, plus the right extensions, is great.

Now, a lot of people publish lists of ‘best’ extensions. It’s quick and easy to make these lists. One difference between my list and some of those “99 Must Have, Best Firefox Extensions!” is that is the real list of the extensions that I use every day. These don’t just sound good, they work well. These are the extensions that have transformed Firefox for me from just a mere Web browser to an essential part of my electronic office.

To me there are two essential Firefox extensions. I would no more run Firefox without it than I would run Internet Explorer. The first of these is Google’s Toolbar for Firefox. This isn’t so much a mere extension as it is a bridge to an entire library of useful Web tools I’m not fond of sticking toolbars on my browser. I’d rather have the screen real-estate for the Web site I’m visiting. When it comes to the Google Toolbar, though, it’s no brainier. I install Firefox, I install the Google Toolbar. It’s that simple.

Vista Adoption going no-where, IT considering Linux and Mac instead

KACE, a systems management appliance company, announced that their recent survey of IT administrators showed that 60 percent of them have no plans to deploy Vista. That’s almost 10% more turning their backs on Vista then in KACE’s last survey in November 2007 . According to the company press release, “42 percent of them said they would consider deployment of alternative operating systems, such as Mac OS and Linux, in order to avoid a migration to Vista.”

11% of Windows users have already decided to switch rather than ‘upgrade’ to Vista. Of that number, 29% plan to changeover to the Mac, followed by 24% to Red Hat Linux, 21% to Ubuntu Linux, and 15% to SUSE Linux. The remainder plan on switching to another version of Linux.

Can the Linux desktop best the Mac desktop?

Mark Shuttleworth, the founder of Ubuntu Linux, wants desktop Linux to "shoot beyond the Mac." Can it?

Shuttleworth was speaking to the open-source faithful at OSCon in Portland, Ore., but I’m sure even they had their doubts.

The Linux desktop is a good, workable one. I’ll take any modern Linux desktop over Windows Vista any day of the week, and the better ones do everything that Windows XP SP3 can do and more. Beating the Mac though? That’s another matter.

Today’s Mac OS X 10.5, Leopard, is a work of the user-interface designer art. My wife recently bought a MacBook Pro, and as I’ve been migrating her data and applications from her elderly XP-powered ThinkPad, I’ve been reminded of just how smoothly integrated everything really is on a Mac. It’s like driving a top-of-the-line Mercedes sports sedan.

There’s a price though that you pay for that wonderful integration of form and function, of application and operating system, and it’s not just the price-tag: it’s all totally proprietary. Apple, and Apple alone, controls the Mac experience. Mac clone maker Psystar, lasted just long enough to show that it really could make a viable Mac clone when Apple fell on them like a ton of bricks with a cease and desist lawsuit that one attorney believes is likely to "put Psystar out of business."

For better, and for worse, the Mac, and Apple’s other top devices like the iPod and iPhone, are the epitome of proprietary design. Everything fits together; everything works, because everything is under Apple’s control. Linux has taken an entirely different course.

Linux distributions start from a common base, the Linux kernel, but then split off as they compete with each other to be the best of the best. Rather than a communism, as Bill Gates would have it, open source is all about Darwinism. It’s non-stop competition where only the best survive.

So, today, to name only some of the most popular distributions, you have a choice of openSUSE, Ubuntu, and Fedora. On top of that, you have a choice of different user-interfaces. The major ones are KDE and GNOME, but others like Enlightenment also have their supporters. And, don’t get me started on the far too many ways there are to install software in Linux.

This competition forces Linux desktops to evolve very quickly. That’s why, while Microsoft has been stumbling with its Vista failure, all of the major Linux desktops zoomed by it. Today, I can still see why Windows users would still use XP over Linux, but Vista? Please!

As fast as the Linux desktop evolves though, it’s hard for me to see it ‘catching’ up with the Mac OS. Their fundamentally different development approaches lead to quite different desktop experiences. With Linux, you tend to get more choices and more power over your desktop. Mac gives you less choice but a more consistent experience. To me, it’s like the difference between a manual and automatic transmission car.

No matter how much the Linux desktop evolves it’s not going to turn into an automatic. Even when Linux does move in that direction, as I would argue it does with the GNOME interface, it will never equal the Mac’s integration of application, operating system and hardware. To even try to equal the Mac experience, a vendor would need not just to be a Linux distributor, but a software vendor and hardware manufacturer as well.

"Can we go right past Apple in the user experience we deliver?" Shuttleworth asked his audience. I’m afraid the answer is no.

On the other hand, Linux has other virtues that the Mac can’t deliver. It’s open, it’s flexible, and it gives the user far more control over their desktop.

So, while I can’t see Linux ever equaling the Mac at what a Mac does, I can see it being its equal in capability. It’s just a matter of choice. Would you rather drive an automatic or a manual? Me, I like both, but at day’s end, I prefer driving manual transmission cars and having the final say on what happens and what doesn’t on my Linux desktop.
