Here come the RHEL 5 clones

If imitation is the sincerest form of flattery, Red Hat should be flattered. Less than two weeks after the company introduced RHEL 5 (Red Hat Enterprise Linux 5), StartCom Ltd. released the first RHEL 5 clone, StartCom Enterprise Linux AS-5.0.0.

StartCom announced on its website that it was launching “a release candidate of our upcoming StartCom Enterprise Linux AS-5.0.0 codenamed ‘Kishuf.’ We invite anybody interested to install this test release and help us find eventual problems in this distribution prior to its official release.”

Although the official release of AS-5, including the x86_64 architecture, is scheduled for for April 2, DVD ISO images of the release are already available for download on the company’s mirrors, here (direct link to ISO), here (direct link to ISO), and here (direct link to ISO).

Besides being installable from DVD, you can also install this distribution over the network or by USB-key.

Of course if you go with a cloned RHEL, while you get the code goodies, you don’t get Red Hat’s support. Various Red Hat clone distributions, such StartCom AS-5, CentOS, and White Box Enterprise Linux, are built from Red Hat’s source code, which is freely available at the Raleigh, NC company’s FTP site. The “cloned” versions alter or otherwise remove non-free packages within the RHEL distribution, or non-redistributable bits such as the Red Hat logo.

StartCom Enterprise Linux AS-5 is specifically positioned as a low-cost, server alternative to RHEL 5. This is typical of the RHEL clones.

These distributions, which usually don’t offer support options, are meant for expert Linux users who want Red Hat’s Linux distribution, but don’t feel the need for Red Hat’s support.

Apple TV: First Thoughts

Eager tech toy users and media addicts are already tearing–sometimes literally–into Apple’s answer to the media extender: the Apple TV.

With the Apple TV, formerly known as iTV, watch can watch your iTunes library’s digital media on your television. With this, you’ll no longer be locked into an iPod’s 2.5″ (diagonal) display. That’s not a small difference. After all, which would you rather watch, a 2.5-inch LCD screen or 34-inch plasma display?

Switching your Linux systems to the new DST

Spring forward; Fall back,” That’s the way the saying goes. Some years I get it backwards, but I eventually catch on. I’ve never had to worry about my PCs getting it wrong before, though. Now, with the recent changes in the Daylight Savings Time (DST) rules, I do.

Fortunately, there are ways to make sure that both my Linux computers and I get the new rules right.

The easy, Wine way to run Windows apps on Linux

Many would-be Linux users don’t make the leap because there are one or two Windows applications they just can’t live without. That doesn’t have to hold them back anymore.

Thanks to Wine (Wine is not an emulator), an open-source implementation of the Windows API (application programming interface), you can run many of the most popular Windows programs on Linux. That includes games like World of Warcraft and Diablo II as well as business applications like Microsoft Office 2003, Quicken, and Internet Explorer.

The easiest way to use Wine to run Windows applications is to set them up with CodeWeavers’s CrossOver Linux 6.0, the new version of its CrossOver Office. I’ve been using CrossOver for years, and it works just fine.
With CrossOver, I’ve been running IE 6, along with the core fonts and Windows Media Player 6.4, since IE (Internet Explorer) 6 started showing up on a wide variety of Linuxes. Now I install these two plus Office XP on almost all of my Linux workstations. None of them are my first choice of programs in their category. (For instance, Firefox has it all over IE in my book.) Still, every now and again, I run into Web sites or file formats that require Microsoft software; so it’s pretty darned handy having them available.

Thanks to Wine, these three Windows programs ran flawlessly with Linux in any distribution I tried. Other programs worked smoothly on some versions of Linux, but needed some tweaking on others. For example, iTunes played perfectly on MEPIS; but I had to play with its configuration on the SUSE family before it would play properly.

I also use CrossOver to run some of the Windows programs I like better, such as iTunes, QuickTime Player, and Quicken 2005, on my Linux boxes. I’ve been able to run all of these combos — including the unholy trio above — successfully on openSUSE 10.2, SLED (SUSE Linux Enterprise Desktop) 10, SimplyMEPIS 6.01, and Ubuntu 6.06. You can find a list of all the Windows programs that have been tested for operation on Linux via CrossOver, here.

At $39.95, CrossOver Linux 6.0 Standard isn’t going to break you. CrossOver Linux 6.0 Professional, the enterprise version of the product, is priced at $69.95, with optional volume discounts. The Professional version comes with a higher level of support and enables system administrators to bundle a CrossOver-Linux install, as well as any Windows applications installed under CrossOver, as an RPM package. You can then use this RPM to deploy CrossOver and Windows applications to Linux workstations across your network.

Of course, you don’t have to use CrossOver — you could install Wine and certain Windows applications by hand. One thing you can’t do on your own, though, is install the Windows OS on top of Linux. For that, you need a virtualization program like KVM (kernel-based virtual machine for Linux), Xen, or the just released Parallels Desktop.

However, only a real Linux expert would want to install and configure Wine and Windows programs by hand. If you want to give it a try, you’ll find handy pointers in the Wine support section. Frank’s Corner, a site devoted to installing and using Wine, can also be a big help.

To get an idea of how beneficial automated Wine installs can be, you can try CrossOver Linux for free; but there are free alternatives, too. These tend to be script programs that automate installing Wine and some Windows applications.

One alternative, WineXS, has done well for me on SUSE-based distributions. WineTools is a little rough around the edges; but it lets you install more Windows programs than with WineXS does.

Finally, there’s IEs4Linux. This program does one thing, and (after some teething problems in earlier versions) it does it very well: it installs Internet Explorer 5, 5.5, and 6. You don’t get the Media Player or any of the other trimmings thrown in, though. IEs4Linux just gives you the browsers themselves so you can test Web site designs and make use of IE-specific Web sites. It comes with simple command line instructions on how to install the program and any of those three versions of Explorer on Debian, the Ubuntu family, SUSE, Fedora, and Gentoo.

So the next time you think, “I’d love to move to Linux, but I need to run this one Windows program,” check out some of these options. You might find that you can have your cake and eat it, too, as long as you have it with Wine.

BitTorrent jumps into (DRMed) Video Distribution

Forget about HD-DVD vs. Blu-ray, the future of television is the Internet. BitTorrent, the company behind the world’s most popular peer-to-peer protocol around gets that. What it doesn’t get is that restricting its rental and purchasable videos to Windows Media compatible formats is downright foolish.

First, here’s what BitTorrent is doing. It’s made a deal with a host of movie and television companies to make some of their content legally available over the net by the BitTorrent protocol. Its partners include: 20th Century Fox, Lions Gate, MTV Networks, Paramount Pictures, Warner Bros. Home Entertainment and Metro-Goldwyn-Mayer Studios.

BitTorrent claims that its network includes “The most comprehensive catalog of on-demand movies, TV shows, Music, and Games on the Internet, with over 5,000 titles (more than 10x what iTunes has to offer), over 40 hours of HD programming, first run films that will be available before they are released on DVD, and unique editorial content that won’t be found anywhere else.” New movies available from the service include Little Miss Sunshine, An Inconvenient Truth, Superman Returns, and The Poseidon Adventure.

Show us the code: right pew, wrong church

Along the lines of early efforts to derail SCO’s claims that Linux infringes Unix copyrights, a gentleman going by the moniker, “digduality” has decided to fight recent claims by Microsoft CEO Steve Ballmer that Linux infringes on Microsoft patents, by launching ShowUsTheCode.com.

As you might guess from its name, the website’s theme is: “since you, Microsoft, claim to be so sure of yourself: Show Us the Code.”

In the few days since its Feb. 23 launch, the website has gained a great deal of attention on such sites as Digg, Linux Today, and Slashdot. Most of the people who have weighed in with comments on the issue have strongly voiced their support. They too want Microsoft to show “the public the code within Linux that violates their intellectual property by May 1st, 2007.”

It sounds like a good idea; but unfortunately, it misses the point.

In Microsoft’s latest FUD (fear, uncertainty, and doubt) campaign — make no mistake, that’s exactly what this is — Ballmer is not claiming that Linux contains any kind of Microsoft copyright violations. That was, at one time, SCO’s claim, not Microsoft’s.

In this assault on Linux, Ballmer is broadly hinting that Linux is infringing on Microsoft’s enormous patent portfolio. And, when it comes to patents, there is no “code” to be shown.

That is part of the diabolic evil, as I see it, of the American patent system. With many, perhaps most, software patents there is no specific language, no hard code, but only descriptions of general processes that can be implemented in multiple ways.

As Bradley M. Kuhn, executive director of the Free Software Foundation (FSF) told me a few years back, it’s “difficult today to write any software program — be it free software or proprietary — from scratch that does not exercise the teachings of some existing software patent in the U.S.A.”

Back when Ballmer first started taking talking about Linux patents in 2004, Dan Ravicher, an attorney and executive director of PUBPAT (the Public Patent Foundation) said, “There is no reason to believe that GNU/Linux has any greater risk of infringing patents than Windows, Unix-based or any other functionally similar operating system. Why? Because patents are infringed by specific structures that accomplish specific functionality.”

The issue has come up again because of the Microsoft/Novell agreement‘s patent collaboration agreement. Novell CEO Ron Hovsepian said of that agreement that it “is in no way an acknowledgment that Linux infringes upon any Microsoft intellectual property. To claim otherwise is to further sow fear, uncertainty and doubt, and does not offer a fair basis for competition.”

Microsoft, then and now, says simply that “Microsoft and Novell have agreed to disagree on whether certain open source offerings infringe Microsoft patents and whether certain Microsoft offerings infringe Novell patents.” And, Ballmer continues his FUD.

I’m sorry to say that the “show the code” campaign won’t stop this. It won’t impede the patent FUD at all.

What we really need is a complete revision of the U.S. patent system. Software patents should be done away with — it’s that simple, in theory. In practice, we’re stuck with this mess.

Ironically enough, Microsoft would agree. On Feb. 22, Microsoft was socked with a $1.52 billion patent judgment in favor of Alcatel-Lucent. The judgment was about one-third of what Alcatel-Lucent had asked for, and it was still the largest patent award in history. Perhaps Ballmer will be a little less inclined to threaten with the patent sword now. After all, the companies that support Linux, such as IBM, Oracle, Red Hat, and many others, have patent holdings that dwarf even Microsoft’s own. Does Microsoft really want to play a game of mutually-assured destruction by software patents? I doubt it.

The patent system is truly dysfunctional, both for proprietary and open source software companies. Behind Ballmer’s bluster, I think he knows that too. That won’t stop him, mind you. After all, it scares corporate customers into sticking with Microsoft, and protecting and growing Microsoft’s bottom line is what he gets paid the big bucks for.

So, since we’re stuck with this FUD, you may want to consider giving your support to PUBPAT, the Linux Foundation’s patent commons, and the SFLC (Software Freedom Law Center) for their work against software patents and for SFLC.
