munchola sends us word that the Open Source Initiative is getting tough on any vendors who claim to be open source despite not actually using a license approved by the OSI. In his blog post, OSI president Michael Tiemann writes: "Enough is enough. Open Source has grown up. Now it is time for us to stand up. I believe that when we do, the vendors who ignore our norms will suddenly recognize that they really do need to make a choice: to label their software correctly and honestly, or to license it with an OSI-approved license that matches their open source label."

lymeca writes "LinuxWorld reports that Sun Microsystem's ZFS filesystem has been converted from its incarnation in OpenSolaris to a module capable of running in the Linux user-space filsystem project, FUSE. Because of the license incompatibilities with the Linux kernel, it has not yet been integrated for distribution within the kernel itself. This project, called ZFS on FUSE, aims to enable GNU/Linux users to use ZFS as a process in userspace, bypassing the legal barrier inherent in having the filesystem coded into the Linux kernel itself. Booting from a ZFS partition has been confirmed to work. The performance currently clocks in at about half as fast as XFS, but with all the success the NTFS-3g project has had creating a high performance FUSE implementation of the NTFS filesystem, there's hope that performance tweaking could yield a practical elimination of barriers for GNU/Linux users to make use of all that ZFS has to offer."

TimHunter writes "I was skeptical when I first saw the title of David Berube's new book, Practical Ruby Gems, from Apress. Do Ruby programmers really need a book devoted entirely to add-on libraries? Most Ruby programmers already know about the RubyGems package management system, and most already have their set of favorite gems. About a third of the way through the book I grudgingly admitted that Rubyists might be able to use this book. After all, even long-time Ruby programmers are unlikely to know about all the gems covered in this book. So then I had a new question. Would I find something in this book that made me say 'I didn't know you can do that with Ruby!'" Read on for the rest of Tim's review.

cyclop writes "I am coding a data analysis application in my laboratory that I would like to release as free (as in freedom) software. Moreover I am going to begin a small OSS game that will be based, in part, on GPLv2 libraries. Problem is: in both cases, I'd like to be able to exchange code both with GPLv2 and (future) GPLv3 projects. I have no particular passions about either license — only thing is I don't want BSD-style 'do anything you want' licensing but a copyleft license. I know that GPLv2 and GPLv3 are not compatible. What can I do? Double licensing? Is there a compatible-with-both license? Adding exceptions? What do you think is the best way to address the GPLv2-to-GPLv3 transition without ending up on one or the other side of the barricade?"

Ravi writes "What does it take to start writing programs for Linux? Most people will guess a text editor, knowledge of a programming language, the compiler and libraries of that language. Ask a professional programmer and he will differ with you. Insisting that while those things can help get you started, other things come into play in writing efficient programs such as, a debugger, memory profiler tools and above all a good understanding of the inner working of the Linux kernel and its processes." Read below for the rest of Ravi's review.

pfaffman sends us word of a two-part article in LinuxInsider that lays out to an audience of non-tech educators a cogent argument for using F/OSS in schools. The piece was written by a University of Tennessee professor for the education journal TechTrends. It makes the case that proprietary software is inconvenient and that when schools choose to use proprietary products they spend their constituents' money. The article won't contain a whole lot of surprises for Linux initiates (save perhaps some software recommendations for educational use), but it's interesting to see these ideas presented so clearly to a wider, and influential, audience."

Bob Uhl writes "I've just finished reading a review copy of O'Reilly's latest GNU/Linux title, Linux System Administration. It's a handy introduction for the beginner GNU/Linux sysadmin, and a useful addition to an experienced sysadmin's bookshelf. The book is essentially a survey of various Linux system-administration tasks: installing Debian; setting up LAMP; configuring a load-balancing, high-availability environment; working with virtualization. None of the chapters are in-depth examinations of their subjects; rather, they're enough to get you started and familiar with the concepts involved, and headed in the right direction." Read below for the rest of Bob's review.

whitehartstag writes with a link to a Network World article about statements from Xandros in the wake of their Microsoft deal. Xandros CEO Andreas Typaldos made a point of stating that they don't believe their product violates any of Microsoft's patents. Nor, he said, did the software giant share with them exactly which patents they believe Linux violates. Just the same, he's disappointed with the reaction they've received from the open source community. "Feedback from the Linux community has been on the order of 'you shouldn't really be talking to the devil.' Linux and open-source advocates believe it is a big issue and say the Xandros deal, and another signed by Novell with Microsoft last year, erodes open source licensing provisions especially around intellectual property issues. Indeed, the Free Software Foundation is rewriting its GNU General Public License (GPL) 3.0 to prohibit such patent deals in the future."

lisah writes "After keeping users waiting for nearly six years, Emacs 22 has been released and includes a bunch of updates and some new modes as well. In addition to support for GTK+ and a graphical interface to the GNU Debugger, 'this release includes build support for Linux on AMD64, S/390, and Tensilica Xtensa machines, FreeBSD/Alpha, Cygwin, Mac OS X, and Mac OS 9 with Carbon support. The Leim package is now part of GNU Emacs, so users will be able to get input support for Chinese, Tibetan, Vietnamese, Thai, Korean, and other languages without downloading a separate package. New translations of the Emacs tutorial are also available in Brasilian Portuguese, Bulgarian, simplified and traditional Chinese, Italian, French, and Russian.'"

chessweb writes "Here is a rather enlightening article by Richard Stallman on the reasons for moving to GPLv3 that puts the previous TiVo post into the right context." From the article: "One major danger that GPLv3 will block is tivoization. Tivoization means computers (called 'appliances') contain GPL-covered software that you can't change, because the appliance shuts down if it detects modified software... The manufacturers of these computers take advantage of the freedom that free software provides, but they don't let you do likewise... GPLv3 ensures you are free to remove the handcuffs. It doesn't forbid DRM, or any kind of feature. It places no limits on the substantive functionality you can add to a program, or remove from it. Rather, it makes sure that you are just as free to remove nasty features as the distributor of your copy was to add them."

Preedit writes to tell us that those busy folks over at InformationWeek have been scrutinizing yet more SEC filings, and Novell and Microsoft aren't the only ones concerned about certain provisions in the final draft of GPLv3. TiVo worries too. The problem is that TiVo boxes are Linux-based. They're also designed to shut down if the software is hacked by users trying to circumvent DRM features. But GPLv3 would prohibit TiVo's no-tamper setup. "If the currently proposed version of GPLv3 is widely adopted, we may be unable to incorporate future enhancements to the GNU/Linux operating system into our software, which could adversely affect our business," TiVo warns in a regulatory filing cited by InformationWeek."

An anonymous reader writes "The most notable changes found in this latest draft include making GPLv3 compatible with version 2.0 of the Apache license, ensuring that distributors who make discriminatory patent deals after March 28 may not convey software under GPLv3, adding terms to clarify how users can contract for private modification of free software or for a data center to run it for them, and replacing the previous reference to a U.S. consumer protection statute with explicit criteria for greater clarity outside the United States. The draft also does not prohibit Novell from distributing software under GPLv3 'because the patent protection they arranged with Microsoft last November can be turned against Microsoft to the community's benefit,' FSF executive director Peter Brown said."

An anonymous reader writes "The OLPC project has announced a three-day game development jam session is scheduled to begin June 8 on the campus of Olin College, an engineering school in Needham, Massachusetts. 'The game jam is an opportunity for developers to create new types of games that rely on features of the XO's design such as mesh networking between nearby users, an integrated still or video camera, and a tablet mode for mobile gaming. Beyond creating games that teach specific tasks like counting or reading, OLPC hopes the contest will produce templates that allow kids to build their own games, according to OLPC's development guidelines.' The grand prize is a free OLPC laptop. All games created at the weekend-long event will be licensed under the GNU General Public License, and posted on the SourceForge site."

InfoWorldMike writes "On the back of defending the agreement this week, Novell did as promised and published details of its landmark November 2006 Linux partnership agreements with Microsoft. Linux advocates are expected to scour the documents for signs of how the agreement may affect Linux and whether anything in it will put Microsoft or Novell in potential violation of the upcoming version 3 of the GNU General Public license (GPL). The GPL is used in licensing many components of the Linux operating system. Open-source advocate Bruce Perens said he would be looking to see exactly what Novell was given through the deal and whether there is any requirement for the Linux vendor to defend Microsoft's patent claims. 'What I'm actually looking for is, to what extent was there a violation of faith?' he said."

QCMBR writes "A new Microsoft-funded study by a Harvard Business School professor concludes that developers don't want extensive patent licensing requirements in the GPL3. There are significant problems with the study, however, especially given the very small sample size. 'Although 332 emails were sent to various developers, only 34 agreed to participate in the survey — an 11 percent response rate. Of the 34 developers who responded, many of them are associated with projects like Apache and PostgreSQL that don't even use the GPL.' Ars points out that the GPL3 draft editing and review process is highly transparent and inclusive 'to an extent that makes MacCormack's claims of under-representation seem difficult to accept given the small sample size of the study and the number of respondents who contribute to non-GPL projects.'"

michuk writes "Nine people involved in a community portal Napisy.org were held for questioning by the Polish police forces this Wednesday. They will be probably be accused of publishing illegal translations of foreign movies (which is forbidden by Polish copyright law). Napisy.org website was shut down immediately afterwards by the German forces (since the servers were located in Germany). The service was the most popular Polish on-line portal where users were free to submit translated subtitles for popular movies. 'According to Polish copyright law any "processing" of others' content including translating is prohibited without permission. The people held (aged 20 - 30) were questioned on Wednesday and Thursday and then allowed to leave. In case of being accused of illegal publishing of copyrighted material, they can spend in jail up to 2 years (in the worst case).'"

GameDev.net reports that Cryptic Studios (makers of the Massive title City of Heroes) has released a powerful animation tool under the GPL. Called CrypticAR, for Cryptic Animation Rig, the software will allow animators to bring 3d models to life via a toolkit of scripts and rigs. "'Our goal is to foster a community of animators by providing them the power to generate animations without having to worry about supporting a toolset. Since we were already developing the rig for our core technology team, we decided to release it to the public under the GNU GPL,' said Shayne Herrera, Art Development Director for Cryptic Studios. 'We feel that the development and gaming communities will benefit greatly from a professional tool like the Cryptic AR.'"

AlexGr writes to recommend an account of a meeting a couple of months back of representatives from more than 100 software companies discussing the state of open source software. The outcome is outlined in a 16-page report, 2007 Open Source Think Tank: The Future of Commercial Open Source (PDF). Among the surprising conclusions: participants noted a growing similarity in methods between open source and proprietary software development. They predicted some kind of convergence, where the best of both approaches gets adopted in each camp.

MsManhattan writes "A year after announcing its plans, Sun Microsystems has made almost all of the core technology in Java available as open-source software under the GNU general public license version 2 (GPLv2). However, some of the code remains 'encumbered'; that is, Sun doesn't have sufficient rights to release it under GPLv2, and the company is requesting the open-source community's help in resolving these issues. Rich Sands, community marketing manager for OpenJDK community at Sun, would not say what percentage of Java's 6.5 million lines of code are encumbered, but explained that it is largely Java 2D graphics technology, such as font and graphics rasterizing."

krelian writes "Talking at Netbeans Day, Rich Green, Sun executive vice president for software, expressed doubts about the current open source model in which developers create free intellectual property only to have others scoop it up and generate huge amounts of revenue. Green said, 'I think in the long term that this is a worrisome scenario [and] not sustainable. We are looking very closely at compensating people for the work that they do.'" Green didn't provide any details about how payments from Sun or others might work.
