Eric Raymond on desktop Linux

Eric S. Raymond is one of the founders of open-source, and a good deal of Linux’s early popularity came from his non-stop beating of the drum for the free software operating system. Then, a few years ago, he bowed out of the limelight to live his own life.

Recently, however, Raymond shows signs of once more playing a bigger role in open-source circles.

When he appeared at the recent August LinuxWorld Expo in San Francisco, he said several things that some Linux fans will find more than a little controversial. Raymond and I, who go back far too many years together, also talked about the issues in a bit more detail out of the public’s eye.

For example, Raymond believes that within the next two years, the Linux desktop must grab a large share of the desktop market or it will never happen. His logic is that historically users shift operating systems when the hardware platform underneath them fundamentally changes.

That’s what happened when PCs went from CP/M-driven 8-bit computers, like the KayPro and the Osborne, to the MS-DOS 16-bit systems of IBM and Compaq. After that, Windows and Mac OS took over on 32-bit systems from Dell and Apple.

Now, we are moving from the 32-bit world to a 64-bit one. Raymond thinks that if Linux doesn’t grab its share of the desktop now, it will never get the chance.

And, how can the Linux vendors do it? Well, for starters, they must switch over to 64-bit computing as fast as possible.

It will take more than that, though. Linux has been running on 64-bit architectures for years. Indeed, it’s often been the first desktop operating system to appear on 64-bit chips like Intel’s Dual Core Processor and AMD’s Opteron.

Linux, Raymond is sure, also needs, one way or the other, to support proprietary equipment like iPods. “When a twenty-something year old comes up to me and I talk to him about Linux, the first thing he wants to know is: ‘Can I run my iPod on it?'”

Saying, as some do, that Linux should only support non-proprietary, DRM-free (digital-rights-management-free) media formats, like Ogg Vorbis, misses the point. If desktop Linux doesn’t become popular, no one will use it, and the open formats will become mere curiosities.

Thus, Raymond is certain that Linux must, no matter how painful it may be to some open-source purists, support popular proprietary software at least on the level of “user-space” applications. If that means paying licensing fees to the Microsofts of the world so that people can watch Windows media files, then so be it.

Raymond’s position could be described as an open-source version of realpolitik, the political concept that one must deal with issues as they really are, as opposed to how we wish them to be.

So, in the case of iPods, you can object all you like to Apple’s FairPlay DRM, but in the real world, if you want to get people using Linux desktops, you need to enable them to use FairPlay-compliant iPod software.

This is, to say the least, not a popular position with many current Linux users or companies. Of the dozens of popular Linux distirbutions, only Linspire’s Freespire takes this approach. And, this has proven to be a very controversial position.

With Raymond back on the open-source scene, and pushing his own vision of how the Linux desktop should evolve, the arguments are only beginning. Like it or not, the Linux desktop is going to be getting a real kick in the pants.

It will be more than a little interesting to see how this all plays out, especially as Microsoft’s Vista slowly, creakingly makes its way to purported January 2007 launch date.

HP offers Debian support for its servers

HP and Debian Linux may not sound like an obvious pairing, but on August 14 at LinuxWorld in San Francisco, HP announced that it has increased its Linux distribution support options for customers and will now support Debian Linux.

Specifically, HP will be supporting Debian Linux across its HP ProLiant and HP BladeSystem server lines. While Red Hat, Novell SUSE, the Asianux foundation of Miracle, Red Flag, and Haansoft remain HP’s first choice of Linuxes for its customers, it has been working internally with Debian since the Linux community’s beginnings in 1995.

HP will provide Debian technical support for installation and configuration during a server’s warranty period. The company, according to sources close to HP, will also offer “care packs” for Debian in the future. Care packs will essentially be service packs.

This support plan is not wedded to a particular Debian distribution. Debian Sarge will be the first Debian distribution to be supported. Etch, when it’s released, will also be supported.

The company also has no plans to sell, market, or certify Debian on HP hardware. So, why do it?

This new support plan was created to meet customer demand. The new support isn’t just for any server administrator, though — it’s for expert Linux administrators who prefer to use Debian for its cost advantages over commercial Linuxes such as RHEL (Red Hat Enterprise Linux) and SLES (SUSE Linux Enterprise Server). At the same time, though, these administrators do want some help from time to time with specific Debian and HP hardware server problems.

HP will also be shipping, with its fully supported distributions, remote monitoring and diagnosis tools with each HP server.

The company is also going to release a Debian Linux-based, thin client — the HP t5725 Thin Client. This trade paperback-sized thin-client can be customized with thousands of Debian applications to meet the requirements of both mainstream users and specialized industries, such as retail and health care.

“HP is continually working to provide customers with the confidence they need to incorporate and integrate Linux and open source into their enterprise,” said Christine Martino, HP’s Open Source and Linux VP in a statement. “Today’s announcement demonstrates HP’s customer successes and opens the door for even more customers to take advantage of open source.”

Desktop Linux breakthrough: Lenovo preloads SUSE on ThinkPad

Finally. For years, the holy grail of the Linux desktop has been to get a major computer vendor to commit to preloading a Linux desktop. It finally happened.

On August 4th, we found out that Lenovo Group, the company that has taken over IBM’s Personal Computing Division, had made a deal with Novell Inc. to preload SLED 10 (SUSE Linux Enterprise Desktop) on its ThinkPad T60p mobile workstation.

For the first time, a major OEM (original equipment manufacturer) has committed to preloading a Linux desktop.

For years, you could get preloaded Linux from smaller vendors. Linspire, MEPIS, and Xandros all have arrangements with second and third-tier OEMs to produce preloaded Linux PCs and laptops. If you were a big-time customer ordering hundreds of systems at a crack, you could also get a major OEM to preload Linux for you.

Over the years, HP has flirted with offering desktop Linux. For example, in 2004, it released the Compaq nx5000 laptop with SUSE Linux 9.1 as a “test” launch. Dell has slowly moved closer to offering a real Linux desktop, but it’s not there yet.

Of course, both HP and Dell will sell you a computer without an operating system, or with FreeDOS and their best recommendation for a Linux for that system, but that’s really not the same thing.

So, if you were just Joe User in North America, and you wanted to simply order or pick up at a store a brand-name computer with a brand-name Linux, you were out of luck.

That was then. This is now.

The T60p isn’t just any laptop. It boasts a high-end, 2GHz Intel Core Duo processor T2500, with a minimum of 512MB of RAM, which can be pushed up to 2GB of memory. For graphics, it uses an ATI FireGL V5200 with 256MB of RAM.

The system is also expected to come with what Lenovo is calling a “ThinkPad Experience” under Linux, which includes: Access Connections, Configuration Utility, Power Manager, warm and cold docking support for USB and video, and Help Center support.

Ironically, in June, Lenovo was in hot-water with Linux fans because an executive had said that the company would no longer support Linux on its ThinkPad line.

Lenovo quickly distanced itself from these comments. “Lenovo’s Linux strategy has not changed … compared to what the IBM Linux-related strategy, related to the PC environment, was,” said Marc Godin, Lenovo’s VP of marketing for notebooks at Lenovo in an eWEEK interview.

Godin then foreshadowed this day, “We’re about to reinforce that strategy and go beyond what IBM or Lenovo, until now, was doing in terms of its commitments to the Linux community ? and to our business partners who want to use Linux.”

In a way, it’s not a surprise at all. Lenovo has been playing second-fiddle to market-leaders Dell and HP for quite some time. Recently, it’s been making moves to improve its status as a top-tier player by becoming the first to offer an AMD processor-based desktop to the enterprise.

So, adding Linux to Lenovo’s offerings makes perfect sense.

I’ve said it before and I’ll say it again: offering Linux as an OEM — big or small — is a smart move.

First, you automatically get a great deal of interest from a passionate, albeit small, group of desktop users. So, why would you want to bother, since Linux desktop users are only measured in single digits of the market?

Because, when everyone else is offering XP, you need to offer something different. If everyone is selling white bread, don’t you think offering whole wheat or raisin bread might earn you some loyal customers? In this case, loyal customers who will spread the word that you’re a good dealer?

From a user’s viewpoint, this move is great. They can finally just buy a fully-functioning Linux laptop, without worrying whether they need to install this to get the WiFi to work, or to download that to read an Adobe Acrobat document. The system will, or at least it should, be ready to work out of the box.

After all, Linux on the ThinkPad has long been supported first by IBM, and more recently, by Lenovo. In addition, the ThinkPad PC product line has probably had more specific Linux support than any other computer brand. In fact, one of the most useful Linux community sites, ThinkWiki, is devoted to nothing but Linux on the ThinkPad.

While we still don’t have all the details yet, some things I already know.

First, this is a major step forward for the Linux desktop. It may not be as big as when Corel introduced the first user-friendly Linux desktop — now Xandros — in 1999. But it’s big.

Second, I think this is a great move for both Lenovo and Novell. Both companies have been in the doldrums recently. Both needed to shake things up. And, this, this is a move that will shake up not just the Linux desktop market, but the desktop market as a whole.

I think that the Lenovo ThinkPad T60p mobile workstation will only be the first of many more mainstream Linux desktop systems. By itself, it may not look like much, but then so the one fateful snowflake which starts an avalanche.

Linspire goes free, bundles proprietary goodies

Linspire CEO Kevin Carmony unveiled Freespire, a no-cost version of Linspire’s Linux distribution, in his keynote address at the Desktop Linux Summit on April 24. Freespire will be offered in both a completely open-source version as well as one that includes proprietary software, Carmony said.

The first beta release of Freespire will be made available for download in August, according to Carmony.

In his remarks, Carmony explained that Freespire will be a community-driven distribution, but that unlike other Linux distributions, it will allow users the choice of downloading a version that is almost entirely open source, or one that includes proprietary software.

Hot-button issue

Including proprietary software within a Linux distribution has long been a hot-button issue in Linux circles. Arguments over how proprietary or license-restricted code can — and cannot — be used with Linux have been raging for years.

Perhaps the most famous example was the use of TrollTech’s Qt library in the popular KDE Linux desktop. It wasn’t until Trolltech made the C++ library and related tools available under a dual license plan, with a GPLed version for Linux and other open-source uses, that the heated debate over the issue finally subsided.

In recent years, Linux distributors have tended to make some proprietary desktop programs, such as Adobe Acrobat and RealNetworks RealPlayer, available as optional downloads. However, in the case of drivers — such as laptop WiFi drivers — that work in closer association with the Linux kernel, distributors have generally avoided including them.

For example, in SUSE 10.1 betas and release candidates, the madwifi driver for the popular Atheros WiFi devices (ath_pci) no longer works by default. Here, the common problem of some of the code being under the GPL, while some is under a proprietary license, arises. The end result is that SUSE no longer ships this driver in its default distribution.

Overcoming desktop resistance

Freespire is thus venturing into new territory by offering a community Linux distro that includes the option to include legally licensed proprietary software pieces within the core distribution.

Carmony explained that Linspire was making this move because Linux on the desktop was meeting resistance due to its lack of native support for some hardware, file types, and multimedia formats.

Freespire addresses this hurdle by offering proprietary drivers and software as a choice, and gives desktop Linux users the option of “out-of-the-box” legal support for MP3, DVD, Windows Media, QuickTime, Java, Flash, Real, ATI drivers, nVidia drivers, Adobe Acrobat Reader, third-party fonts, etc.

Once released, a list of all of Freespire’s different proprietary codecs, drivers, and software will be made available at the site, along with the detailed licensing information needed to help others to modify and redistribute the core.

“Freespire is about choice,” Carmony stated. “The user should be free to decide what software they want to install on their systems, be that proprietary or open source. Linspire fully embraces and supports the open source model, but if Linux is to gain mainstream acceptance, it needs to work with iPods and DVD players, and fully support hardware, such as 3D graphic cards, WiFi, sound, and printers. Until there are viable open source replacements, Freespire sets out to at least provide the option of legally and easily using certain proprietary codecs, drivers, and software.”

No one doubts that many of these licenses are legal in and of themselves. The questions have always arisen in the murky area of how and whether the software they license is legal to distribute with Linux, which falls under the GPL 2.

While this is a matter that developers wrestle with constantly, for users, it usually amounts to having to separately download and install a number of desired proprietary programs and drivers when they start using their Linux systems.

Many proprietary codecs, drivers, and application programs will be offered in Freespire’s core distribution, while a few that have a larger per-unit licensing fee, such as legal DVD decryption, must be purchased and installed via Linspire’s CNR (click and run) service.

Based on Debian, Linspire, Ubuntu, DCC

As part of the Freespire project, Linspire’s CNR technology (a one-click, download-and-install software management system based on the Debian DEB package format), will be open-sourced to facilitate what Carmony calls a truly “free marketplace” for the distribution of all Linux software, including proprietary, open source, free, and commercial.

The new distribution will be based on Debian, Linspire, and Ubuntu, but will mostly be a direct derivative from Debian (Sid). It is also based on the DCC Alliance’s LSB (Linux Standard Base) compliant core Linux.

Initially, the Freespire desktop will be built around the KDE 3.5x environment, but as a community project, GNOME variations could be baked in, Carmony said.

At first, Freespire will only be available for the PC x86 platform. Linspire will be encouraging others to port Freespire to other platforms and architectures such as AMD64, Intel Core Duo, and POWER.

Community involvement

The Freespire project will be open to community development, comment, and contribution. A community forum is now live. The project will be governed by a Leadership Board that includes prominent Linux community members.

The board, which only has half of its members at this point, according to Carmony, currently includes: Carmony; Ian Murdock, founder of Debian, and now the LSB leader; Jim Curtin, CEO of Win4Lin; and Martin Michlmayr, a prominent Debian developer. Carmony said that the board’s other members will be appointed over the next two weeks.

Last summer, an unsanctioned Freespire Linux distribution, which also aimed to provide a free version of Linspire Linux, briefly appeared on the scene. Within a couple of weeks, the distro’s developer reportedly agreed to change the name of his project following a conversation with Carmony, and Linspire offered free copies of Linspire Linux “for a few days” as part of the arrangement.

The new, fully-sanctioned Freespire project will now provide the first sanctioned “free as-in-beer” binary version of Linspire’s Linux.

Novell launched OpenSUSE, the free SUSE Linux project, last summer at LinuxWorld in San Francisco. Red Hat launched Fedora, the free Red Hat Linux project, in 2001.

Microsoft: Too Big for the Law?

A $10 million fine here, a $100 million lawsuit settlement there; it’s just another day of Microsoft doing business.So, the EU finally let Microsoft have it. European Union regulators fined the boys from Redmond 280.5 million euros—thats 357.3 million American dollars—for defying a 2004 antitrust ruling and warned the company that bigger fines were to come.

How big? It could go up to 3 million euros a day after July 31 if Microsoft doesnt toe the line and finally give up proprietary information on how its software works. And I think we can say its a safe bet that Microsoft is not going to cooperate.

To which, I say, “So what?”

In Microsofts last reported quarter, the companys net income was $2.98 billion. Thats what? About $33 million a day of profit—not revenue—profit? So, to Microsoft, paying off the Europeans every day would be about what most of us pay for our morning café latte vente and a cookie at Starbucks.

Linux 2.6.17 kernel: better WiFi, faster performance

This past Saturday, June 17th, saw the arrival of the latest stable version of the Linux kernel: Linux 2.6.17.

While this new kernel doesn’t boast any earth-shaking additions, it does include numerous improvements to Linux for both users and developers.

For many laptop users, the most important news is that Linux now includes built-in driver support for the Broadcom 43xx based wireless card family. This WiFi chip family is found in many laptops such as many models from Acer, Apple (those using Airport Extreme), Compaq, and Dell.

This driver support depends upon another new enhancement to the kernel — the addition of a Softmac layer in the wireless stack. Softmac is a software MAC (machine access control) layer that works with Linux’s built-in 802.11 layer. This provides a great deal of WiFi protocol management features for chips that, unlike the Intel ProSet Wireless chip family, don’t handle these details in hardware.

Softmac is not the only open-source project that takes this approach. MADWiFi, for example, uses one to support Atheros WiFi chips. Since Softmac is now part of the kernel, however, it can be used by developers to more easily support other WiFi chips. There have already been efforts at supporting the Prism54 and the Ralink rt2* 802.11 chip families using Softmac.

Linux’s wireless improvements also include support for Cisco’s LEAP (Lightweight Extensible Authentication Protocol). LEAP is used in Cisco’s and other vendors’ wireless devices, including clients, switches, access points, and RADIUS servers that use 802.1X authentication. In turn, this enables network administrators to easily set up dynamic per-user, per-session WEP (Wired Equivalent Privacy) secured sessions. The bottom line is that it will be much easier to use Linux systems in LEAP-secured networks.

For users, what all this means is that they’ll be much more likely to be able to use their laptops’ WiFi without any fuss or muss.

The new Linux kernel also includes automatic support for SMP (Symmetric Multiprocessing) computers on the i32 and 64 families. With this, Linux distributions will detect how many processors, or conceivably processor cores, are running on the system at boot time. The distribution will then automatically adjust to make the most of the existing architecture.

While at first, this might not appear that useful for many users, with the increasing use of virtual CPUs in virtualization systems like Xen, it might become very helpful in high-powered servers.

Another new development that should be especially useful in servers is the arrival of the new kernel system call, “splice.”

Regarding what splice does, Linus Torvalds wrote:

“So in a very real (but abstract) sense, “splice()” is nothing but read()/write() to a kernel buffer.”

Now, to get slightly less abstract, there are two important practical details.” First, “the “buffer” implementation is nothing but a regular old-fashioned UNIX pipe.”

This actually makes sense on so many levels, but mostly simply because that is exactly what a UNIX pipe has always been: it’s a buffer in kernel space. That’s what a pipe has always been. So the splice usage isn’t conceptually anything new for pipes – it’s just exposing that old buffer in a new way.

The second part of the deal is that the buffer is actually implemented as a set of reference-counted pointers, which means that you can copy them around without actually physically copy memory.”

For those who don’t speak programmer, what this means is that with splice, and other new related calls such as tee and vmsplice, your computer will perform faster. That’s because it will no longer be wasting time copying redundant data from one chunk of memory to another or to a disk.

To cite an example from the new kernel’s changelog, “For example, you could forward data that comes from a MPEG-4 hardware encoder, and tee() it to duplicate the stream, and write one of the streams to disk, and the other one to a socket for a real-time network broadcast. Again, all without actually physically copying it around in memory.”

Speaking of performance boosts, the new kernel has also given the popular Ext3 file system a kick in the pants by supporting mapping multiple block file input/output to disk. In the past, Ext3 could only map one block at a time. This lead to a real speed bump, especially when it came to handling sequential I/O workloads.

Early tests have shown that users could see as much as 50 percent speed increases in some disk writing operations.

There are, of course, many other changes in the new kernel. Not the least of which, is that Linux is now supported on Sun’s new Niagara chip architecture. To sum it all up, though, better WiFi support and performance are the hallmarks of this latest kernel.

For a detailed list of all the changes, see the latest Linux changelog.
