Multi-Server Microkernel OS Genode 12.11 Can Build Itself 102

An anonymous reader wrote in with a story on OS News about the latest release of the Genode Microkernel OS Framework. Brought to you by the research labs at TU Dresden, Genode is based on the L4 microkernel and aims to provide a framework for writing multi-server operating systems (think the Hurd, but with even device drivers as userspace tasks). Until recently, the primary use of L4 seems to have been as a glorified Hypervisor for Linux, but now that's changing: the Genode example OS can build itself on itself: "Even though there is a large track record of individual programs and libraries ported to the environment, those programs used to be self-sustaining applications that require only little interaction with other programs. In contrast, the build system relies on many utilities working together using mechanisms such as files, pipes, output redirection, and execve. The Genode base system does not come with any of those mechanisms let alone the subtle semantics of the POSIX interface as expected by those utilities. Being true to microkernel principles, Genode's API has a far lower abstraction level and is much more rigid in scope." The detailed changelog has information on the huge architectural overhaul of this release. One thing this release features that Hurd still doesn't have: working sound support. For those unfamiliar with multi-server systems, the project has a brief conceptual overview document.

Anthropologist Spends Three Years Living With Hackers 252

concealment writes "Coleman, an anthropologist who teaches at McGill University, spent three years studying the community that builds the Debian GNU/Linux open source operating system and hackers in the Bay Area. More recently, she's been peeling away the onion that is the Anonymous movement, a group that hacks as a means of protest — and mischief. When she moved to San Francisco, she volunteered with the Electronic Frontier Foundation — she believed, correctly, that having an eff.org address would make people more willing to talk to her — and started making the scene. She talked free software over Chinese food at the Bay Area Linux User Group's monthly meetings upstairs at San Francisco's Four Seas Restaurant. She marched with geeks demanding the release of Adobe eBooks hacker Dmitry Sklyarov. She learned the culture inside-out."

Ask Richard Stallman Anything 573

Richard Stallman (RMS) founded the GNU Project in 1984, the Free Software Foundation in 1985, and remains one of the most important and outspoken advocates for software freedom. RMS now spends much of his time fighting excessive extension of copyright laws, digital rights management, and software patents. He's agreed to answer your questions about GNU/Linux, free software, and anything else you like, but please limit yourself to one question per post.

Book Review: Version Control With Git, 2nd Edition Screenshot-sm 116

kfogel writes "Two thumbs up, and maybe a tentacle too, on Version Control with Git, 2nd Edition by Jon Loeliger and Matthew McCullough. If you are a working programmer who wants to learn more about Git, particularly a programmer familiar with a Unix-based development environment, then this is the book for you, hands down (tentacles down too, please)." Read below for the rest of Karl's review.

Google Engineers Open Source Book Scanner Design 69

c0lo writes "Engineers from Google's Books team have released the design plans for a comparatively reasonably priced (about $1500) book scanner on Google Code. Built using a scanner, a vacuum cleaner and various other components, the Linear Book Scanner was developed by engineers during the '20 percent time' that Google allocates for personal projects. The license is highly permissive, thus it's possible the design and building costs can be improved. Any takers?" Adds reader leighklotz: "The Google Tech Talk Video starts with Jeff Breidenbach of the Google Books team, and moves on to Dany Qumsiyeh showing how simple his design is to build. Could it be that the Google Books team has had enough of destroying the library in order to save it? Or maybe the just want to up-stage the Internet Archive's Scanning Robot. Disclaimer: I worked with Jeff when we were at Xerox (where he did this awesome hack), but this is more awesome because it saves books."

The Shumway Open SWF Runtime Project 99

theweatherelectric writes "Mozilla is looking for contributors interested in working on Shumway. Mozilla's Jet Villegas writes, 'Shumway is an experimental web-native (Javascript) runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals: 1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations. 2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.'" See also: Gnash and Lightspark.

The Past, Present, and Future of OSS 150

CowboyNeal writes "The nature of the open source movement and its software over the years has changed considerably. From its humble beginnings in the early 80s to mainstream Android adoption, open source software along with computers and technology as a whole has gone from the sidelines to a prevalent position in the lives of modern consumers."

Rare Photos: Gnu Crashing a Windows 8 Launch Event 313

New submitter Atticus Rex writes "Reporters and security guards at the Windows 8 launch event weren't sure how to react when they were greeted by a real, live gnu. The gnu — which, on closer inspection, was an activist in a gnu suit — had come for some early trick-or-treating. But instead of candy, she had free software for the eager journalists. The gnu and the Free Software Foundation campaigns team handed out dozens of copies of Trisquel, a fully free GNU/Linux distribution, along with press releases and stickers. Once they got over their confusion, the reporters were happy to see us and hear our message — that Windows 8 is a downgrade, not an upgrade, because it steals users' freedom, security and privacy."

Feds Continue To Consider Linux Users Criminals For Watching DVDs 423

An anonymous reader sent in a link to an article in Wired about the latest DMCA loophole hearing. Bad news: the federal government rejected requests that would make console modding and breaking DRM on DVDs to watch them legal. So, you dirty GNU/Linux hippies using libdvdcss better watch out: "Librarian of Congress James Billington and Register of Copyrights Maria Pallante rejected the two most-sought-after items on the docket, game-console modding and DVD cracking for personal use and 'space shifting.' Congress plays no role in the outcome. The regulators said that the controls were necessary to prevent software piracy and differentiated gaming consoles from smart phones, which legally can be jailbroken. ... On the plus side, the regulators re-authorized jailbreaking of mobile phones. On the downside, they denied it for tablets, saying an 'ebook reading device might be considered a tablet, as might a handheld video game device.'" So you can jailbreak a phone, but if it's 1" larger and considered a "tablet" you are breaking the law.

The Greatest Battle of the Personal Computing Revolution Lies Ahead 291

As tablets and computer-phones flood the market, the headlines read: "The Personal Computer is Dying." But they are only half true: an artifact of the PC is dying, but the essence of the PC revolution is closer to realization than ever before, while also being closer to loss than ever before.

FSFE Interview With 'Terms of Service: Didn't Read' Founder 43

An anonymous reader writes with an interesting interview "Hugo's project Terms of Service: Didn't Read has recently won international attention in publications such as TIME, Le Monde, and ZEIT, in its campaign to simplify the legal terms of web services. He is FSFE's French Team coordinator, co-founder of the Digital Freedoms association, and in 2009 did extensive work on the impact of Europe's Interoperability Framework (EIF) on Free Software users."

PS3 Encryption Keys Leaked 284

An anonymous reader writes "PS3 security has been compromised again. The holy grail of the PS3 security encryption keys — LV0 keys — have been found and leaked into the wild. For the homebrew community, this means deeper access into the PS3: the possibility of custom (or modified) firmware up to the most recent version, the possibility of bypassing PS3 hypervisor for installing GNU/Linux with full hardware access, dual firmware booting, homebrew advanced recovery (on the molds of Bootmii on Wii), and more. It might lead to more rampant piracy too, because the LV0 keys could facilitate the discovering of the newer games' encryption keys, ones that require newer firmware."

3-D Model Support Comes To MediaGoblin 37

paroneayea writes "MediaGoblin and LulzBot have teamed up to bring 3-D model support to MediaGoblin! The announcement shows off a live demo of the new feature... it uses Blender on the backend to render stills and thingiview.js to show realtime WebGL previews. This means MediaGoblin is becoming more useful for 3-D artists and people interested in 3-D printing, especially those looking for a free-as-in-freedom alternative to Thingiverse."

Video Eben Moglen Explains Freedom and Free Software in Two Video Interviews Screenshot-sm 78

Eben Moglen, says Wikipedia, "is a professor of law and legal history at Columbia University, and is the founder, Director-Counsel and Chairman of [the] Software Freedom Law Center, whose client list includes numerous pro bono clients, such as the Free Software Foundation." And if that wasn't enough, since 2011 he's been working with FreedomBox, a project working toward "a personal server running a free software operating system, with free applications designed to create and preserve personal privacy." Prof. Moglen is also one of the most polished speakers anywhere, on any topic, ever. That's why, instead of editing this interview Timothy Lord did with him, we simply cut it in half, removed a little introductory and end conversation, and let the Professor roll on. The second half of this interview will run tomorrow. It's at least as worthwhile as the first half, especially if you are interested in Free Software.

The FSF Adopts the Kickstarter Approach To Fund-raising 35

New submitter ChronoEngineer writes "Recently the Free Software foundation launched a new fund-raising system starting with the GNU MediaGoblin project. Rewards from its new tiered donation reward system include physical objects such as a 3D print of the project's mascot as well as digital ones (Rewards List). This gives free software projects an alternative crowd-funding source where all of their contributions go to advancing free software, since the administrative cut taken from the earnings goes to the Free Software Foundation. Chris Webber, of GNU Mediagoblin, mentions this as one of the reasons he chose the FSF over Kickstarter for his project."

Video Freeside Internet Services: Doing Well With Purely Free Software (Video) Screenshot-sm 53

While attending ITEXPO West in Austin, TX, Slashdot editor Timothy Lord met Ivan Kohler, the "President, Founder and Head Geek" of a company called Freeside Internet Services that is 100% open source (no dual-licensing) and makes its living supporting software Ivan says is used to manage some of the very unsexy backend tasks that ISPs and VoIP providers need to do, like track usage and send bills to customers. Freeside uses the AGPL license, which Ivan calls "a GPL variant for web applications" that, he says, "prevents people from taking our software, modifying it, and selling it in a hosted capacity as proprietary software."

Interviews: Ask Free Software Legal Giant Eben Moglen 56

At this summer's HOPE, Eben Moglen was one of the most incisive and entertaining speakers. But since only a small fraction of the Earth's population can fit into an aging hotel meeting room, you can watch his HOPE presentation via Archive.org on making the first law of robotics apply to cell phones. Besides being a professor at Columbia Law, former clerk in U.S. federal court as well as to Supreme Court Justice Thurgood Marshall, and a prolific writer, Moglen is founding director of the Software Freedom Law Center as well as the creator of the FreedomBox Foundation, and was for many years general counsel of the Free Software Foundation. Moglen has strong opinions, and a lot to say, about software licensing and freedom, copyright, patents, and (as you can see from the video linked above) about the privacy implications of always-on, always-on-us technology. Next week, I'll be meeting up with Moglen for a short interview. If you have a question for Eben, please post it below; I can't guarantee how many reader questions I'll have a chance to ask him, but the more, the merrier.

Prime Minister to French Government: Favor FOSS Wherever Possible 112

concertina226 writes with interesting news from France. From the article: "French government agencies could become more active participants in Free Software projects, under an action plan sent by Prime Minister Jean-Marc Ayrault in a letter to ministers (PDF, and in French of course), while software giants Microsoft and Oracle might lose out as the government pushes Free Software such as LibreOffice or PostgreSQL in some areas. ... He also wants them to reinvest between 5 percent and 10 percent of the money they save through not paying for proprietary software licenses, spending it instead on contributing to the development of the free software. The administration already submits patches and bug fixes for the applications it uses, but Ayrault wants to go beyond that, contributing to or paying for the addition of new functionality to the software."
