RidgeRun enables broad, commercial embedded Linux usage for developers

Driving open-source prevalence further into the mass commercial market, RidgeRun, Inc., announced today that it has created dynamic shared library support for developers who are creating a broad variety of applications for embedded devices.

With the industry’s first shared library support for the ARM7 MMU-less Linux environment, developers can use software licensed under the Library GNU Public License (LGPL). RidgeRun made this dynamic link support available with its newly released Board Support Package (BSP) for Texas Instruments’ TMS320VC5471 processor. Without dynamic link support, developers were hesitant to use code licensed under the LGPL if they had a need to keep their application code proprietary for various reasons such as partner licensing agreements or protecting trade secrets.

“Today’s announcement once again demonstrates RidgeRun’s efforts to strengthen Linux in the embedded marketplace,” said Dan George, Vice President of Product Development for RidgeRun. “Manufacturers of embedded products are increasingly moving from home-grown operating systems to Linux-based software such as RidgeRun’s DSPLinux. And while many of our customers have code they prefer to keep proprietary for various business reasons, they are still very interested in contributing to and benefiting from open source development. Shared library support makes this possible, and RidgeRun has allowed those using MMU-less systems to take advantage of this benefit for the first time.”

Other important benefits of shared library support include reduced memory footprint through shared code, and the ability to upgrade libraries used by multiple programs in the embedded device.

FSF asks Lindows, “Where’s the source?”

Tina Gasperson
Bradley Kuhn, vice president of the Free Software Foundation, says the organization is contacting LindowsOS
representatives because the company has not included source code with its “sneak
preview” releases. Lindows CEO Michael Robertson says his company will comply
with the GPL when the product is released to the public.
Kuhn says a Lindows insider tipped the FSF off to the
possibility of missing source code. Lindows insiders are those who have
registered and paid a $99 fee to receive beta releases of LindowsOS and
other non-public information. LindowsOS is a distribution based on the Linux
kernel, which is licensed under the GNU General Public License. The GPL
states, in part, that the program instructions in their original form as written
by the programmer (source code) must be available to users
of the program. The GPL also requires that users be allowed to copy, modify and
redistribute the program freely, but they must in turn provide the source
code.

Robertson does not deny that the source code for LindowsOS isn’t included in
either of the two beta releases. “It’s a work in progress. We’re hopeful our
first release will happen around the middle of the year. When we release an
official version, all the GPL pieces will be properly distributed.”

Robertson doesn’t appreciate the negative attention focused on the Lindows
project, likening it to “eating your young.” He says he is surprised that
“some in the Linux community are quick to cast aspersions, with no facts.”
Robertson points to his contributions to the Open Source community as proof that
he has its best interests at heart, beginning with his career at MP3.com.

“We battled for the consumer at every step. We battled for open formats. We
fought against secure music schemes. And we made contributions to Open Source
software, since MP3.com was entirely LAMP based.”

And now that he’s working on making the Linux desktop a reality, Robertson says
his dedication to Open Source continues. “We’ve joined KDE League at the
highest corporate level. We hosted and sponsored Wineconf 2002. We worked with
the project leader to identify the top 25 contributors and paid for roundtrip
airfare for all of them, from as far away as South Africa and Norway, to San
Diego. There was no registration fee. We also sponsored LPBN.org to broadcast
the event.

“We’ve agreed to sponsor the upcoming Debian conference. Our sponsorship
included funds to pay for an awards banquet for all attendees, as well as travel
support for some. We’ve made a large investment in an Open Source company; we’ve
also paid about a million dollars to get code produced … We’ve paid these funds
to companies as well as individuals.”

And, he says, support for Linux and the Open Source community will also come by
way of ingenious marketing. “If we can get to 5% market share, an ecosystem of
healthy Linux companies will emerge which will be around for the long run. Look
at the incredible things that would happen. Hardware manufacturers will ship
Linux drivers for their peripheral devices, in the box. Computer stores will
dedicate sections of their store. Major OEMs would ship computers with Linux.
It’s a travesty you can’t walk into major retailers today and buy a computer
running Linux.”

And while the code is important, that is not what it will take to get Linux to
“20 million desktops.” Robertson says to help more people understand Open
Source, better marketing and lobbying is needed. “And yes, battling Microsoft
and their huge coffers which influence OEMs, retailers, politicians, and the
press in ways you only understand if you talk to them personally, which I have.

“Hopefully, Lindows.com will contribute on each of these fronts, but it will
take more than one company. It’s a shame that virtually every commercial Linux
company has abandoned the desktop. Our goal is to build a company that will give
consumers a choice for their operating system. At the same time, we’re committed
to being a good corporate citizen and being a supporter of Open Source for the
long run.”

Robertson seems dismayed by the FSF’s attempt to enforce the GPL. “No wonder there’s virtually no healthy Linux companies. The community seems to attack them when the real focus should be elsewhere.”

Robertson says that many of the critical pieces of GPL code that have gone into
Lindows have been distributed back to the community already. “Where do you think
that Codeweavers got their code for Crossover Office?” he asks.

A high level source at Codeweavers confirms that Lindows has indeed
contributed an “enormous amount” of code to the Wine project. But while Crossover
Office contains code that was created in conjunction with Lindows, it has also been built on code that was around before Lindows existed. According to the Codeweavers source, Lindows returned modifications to the Wine codebase only because it was persuaded by Codeweavers staff to return it. The Codeweavers/Lindows association was
terminated
in part because Lindows wanted to be able to keep its Wine modifications
private.

Linux for the everyday desktop: The Lycoris experience

Anonymous Reader writes, “Monolinux has just published the first of a two part review covering the Lycoris (formerly Redmond Linux) distribution. There is very little written about this particular flavor of Linux, so it’s nice that this commentary will describe the installation process and give a general overview of why we should or should not care about this new product.”

Microsoft attacks Free Software developers with new license

Microsoft, in its new “Royalty-Free CIFS Technical Reference License
Agreement”, unequivocally targets Free Software developers who choose
copyleft licensing terms. Microsoft’s new license directly attacks
the GNU General Public License (GPL) and the GNU Lesser General Public
License (LGPL)—-licenses published by the Free Software Foundation
(FSF) and used prominently by numerous Free Software projects
worldwide

Microsoft has veiled this attack in the trappings of a “gift”.
Microsoft agrees to grant royalty-free permission to use and exercise
their CIFS patents in Free Software, but only to a limited set of
developers. Under the guise of fulfilling its obligations under the
anti-trust settlement, Microsoft has singled out developers and
companies who choose copyleft licenses (such as GPL and LGPL).
Software distributors of copylefted software are forbidden from
exercising the patents royalty-free, and thus are effectively
forbidden from exercising the patents at all under copyleft. In
effect, Microsoft has vindicated the warnings FSF
set forth in its Tunney act filing for the Proposed Revised Final
Judgment in United States vs. Microsoft
. Namely, the settlement
terms are not in the public interest because it places insufficient
requirements on Microsoft to give Free Software developers equal and
fair access to its APIs.

Microsoft’s tactics were of no surprise to Bradley M. Kuhn, executive
director of the FSF, who pointed out: “Microsoft’s new assault follows
a year’s worth of rhetoric aimed at slandering the GPL and those who,
in the name of software freedom, advocate the use of GPL. Now, that
war of words has been followed up with a legal attack. As Mundie’s
speeches tried and failed to do last summer, Microsoft seeks to
pressure existing GPL’ed projects to give up copyleft. Microsoft
loves non-copylefted Free Software; it allows them to benefit from the
commons without contributing back. In copylefted Free Software,
Microsoft now faces a rival that they cannot buy nor run out of
business. As expected, they’ve turned to their patent pool as their
last resort to assail us”. Fortunately, developers of GPL’ed code
stand united in rejecting this anti-competitive act by Microsoft. The
FSF is also encouraging key industry leaders who distribute and rely
on GPL’ed software to stand against Microsoft on this matter.

This situation exemplifies the dire threat software patents have
against software freedom. Fortunately, software patents do not exist
in every country. The FSF urges citizens in software-patent-free
countries to demand that their governments categorically reject
software patents. Kuhn noted: “the best way to fight Microsoft as
they offensively assert their patent rights is to convince your
government not to recognize software patents as a legitimate use of
patent law”. The fight against software patents is particularly
urgent in Europe, as the European Union may decide to permit software
patents soon. Europeans citizens are encouraged to support efforts
opposing software patents for the EU. For more information, see

Real-Time and Linux, Part 2: the preemptible kernel

“By improving the kernel, and not changing or adding to the API, applications can run more responsively by merely switching out a standard kernel for the improved one. This is a big benefit. It means that ISVs need not create special versions for different real-time efforts. For example, DVD players may run more reliably on an improved kernel without needing to be aware that the kernel they are running on has been improved.” More at LinuxDevices.

Geodesic seeks more Linux believers

LinuxPlanet: “Geodesic first posted the downloadable Mozilla demo in January of this year, just before Linux World. “We chose Mozilla because it’s a high-profile Open Source program. We know that people are very busy, and that evaluating tools is something that’s hard to find time to do. But we wanted to make the point that our products work,” Spertus says.

Every week or two, Geodesic has posted updated error reports for Mozilla. “And each week, the report gets better, with fewer errors,” he claims. Geodesic’s reports show 10.1KB in leaked memory for Mozilla on March 13, 2002; 6.36KB in leaked memory on March 18; and 2.06KB on March 26.”
