Genode OS 13.02 Features Low Latency Audio, Virtualization, Protected DMA 41

On the heels of their December release, the 13.02 release of the Genode multi-server microkernel OS framework continues to deliver major new features. Under the hood, there's support for the IOMMU, bringing safe bus master DMA to userspace drivers (overcoming one of the final advantages monolithic kernels had). They've also added full virtualization support, good enough to boot Linux as an application. In the cool department, they've added a new low latency audio interface that could very well pave the way for something akin to JACK, and right now provides a lightweight way for the system to beep at you in real time . A few more libraries have been ported (libssh, curl, iconv) in preparation for a port of git to the Noux native GNU runtime. There are also a bunch of other improvements to their NOVA microkernel, support for running on the Exynos 5250 and Freescale i.MX53, a new console multiplexer, improvements to the display server, simplification of the base libraries, and more. I'll be attempting to build it and give it a spin to see how well it works in practice sometime soon.

OpenOffice: Worth $21 Million Per Day, If It Were Microsoft Office 361

rbowen of SourceForge writes with an interesting way to look at the value of certain free software options: "Apache OpenOffice 3.4.1 has averaged 138,928 downloads per day. That is an average value to the public of $21 million per day, as calculated by savings over buying the competing product. Or $7.61 billion (7.61 thousand million) per year." (That works out to about $150 per copy of MS Office. There are some holes in the argument, but it holds true for everyone who but for a free office suite would have paid that much for Microsoft's. The numbers are even bigger if you toss in LibreOffice, too.)

Piriform Asks BleachBit To Remove Winapp2.ini Importer 305

ahziem writes "As author of the BleachBit system cleaner, I received a polite but firm request from Piriform, makers of the similar application CCleaner, to remove a two-year-old feature from BleachBit that allows individual BleachBit users to import winapp2.ini data files created by the community that define which files to delete for applications. Does Piriform's request have merit? Do I need a lawyer? What is a good response to avoid any ugly situation?"

FreeBSD Project Discloses Security Breach Via Stolen SSH Key 86

An anonymous reader writes "Following recent compromises of the Linux kernel.org and Sourceforge, the FreeBSD Project is now reporting that several machines have been broken into. After a brief outage, ftp.FreeBSD.org and other services appear to be back. The project announcement states that some deprecated services (e.g., cvsup) may be removed rather than restored. Users are advised to check for packages downloaded between certain dates and replace them, although not because known trojans have been found, but rather because the project has not yet been able to confirm that they could not exist. Apparently initial access was via a stolen SSH key, but fortunately the project's clusters were partitioned so that the effects were limited. The announcement contains more detailed information — and we are left wondering, would proprietary companies that get broken into so forthcoming? Should they be?"

Video Mike Storey and His Plate Reverb (Video) 163

"Reverberation is the persistence of sound in a particular space after the original sound is produced," says Wikipedia. More often than not, in studio recordings reverb is added digitally; virtually every FOSS or proprietary sound-editing program has a built-in reverb utility. But what if you're the sort of purist who prefers the analog sound of vinyl records to the digital sound of MP3s or CDs? What if you're the kind of musician who records at the original Sun Studio in Memphis to get that original rock and roll sound? That may be overly picky for most musicians, but there are some who would rather sound like Johnny Cash than Flavor Flav, and they're the ones who are going to insist on real analog reverb instead of twiddling a setting in Audacity. There are many types of analog reverbs, of course. One of the purest types, preferred by many audio purists, is the adjustable plate reverb, and Jim Cunnigham's Ecoplate is considered by many to be the best plate reverb ever -- which brings us to Mike Storey, who wanted an Ecoplate-type plate reverb so badly that he spent eight months building one. He'll run your audio files through it for a (highly negotiable) fee, and maybe give you a bit of advice if you want to build your own, although his biggest piece of advice for you (at the end of the video) to think long and hard before you become a home-brew reverberator, with or without advice and components from Jim Cunningham.

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." Read below for the rest of what CowboyNeal has to say.

Trans-Atlantic 8K/UHDTV Streaming With UltraGrid and Commodity PCs 58

An anonymous reader writes "During the 12th Annual Global LambdaGrid Workshop in Chicago, researchers have demonstrated interactive multi-point streaming of 8K/UHDTV (i.e., 16x Full HD resolution) using commodity PC hardware running Linux and open-source UltraGrid software. The transmissions featured GPU-accelerated JPEG and DXT compressions implemented using the NVIDIA CUDA platform, which are also available as open-source software. The streams were distributed from the source to one location in the USA and to another location in the Czech Republic over 10Gbps GLIF network infrastructure."

OpenOffice Is Now, Officially, Apache OpenOffice 266

rbowen writes "Apache OpenOffice has graduated from the Incubator, and now is officially a top-level project at the Apache Software Foundation." From the announcement: "As with all Apache software, Apache OpenOffice software is released under the Apache License v2.0, and is overseen by a self-selected team of active contributors to the project. A Project Management Committee (PMC) guides the Project's day-to-day operations, including community development and product releases. Information on Apache OpenOffice source code, documentation, mailing lists, related resources, and ways to participate are available at http://openoffice.apache.org."

Reiser4 File System Still In Development 317

An anonymous reader writes "Reiser4 still hasn't been merged into the mainline Linux kernel, but it's still being worked on by a small group of developers following Hans Reiser being convicted for murdering his wife. Reiser4 was updated in September on SourceForge to work with the Linux 3.5 kernel and has been benchmarked against EXT4, Btrfs, XFS, and ReiserFS. Reiser4 loses out in most of the Linux file-system performance tests, has much stigma due to Hans Reiser, and Btrfs is surpassing it feature-wise, so does it have any future in Linux ahead?"

Notch Won't Certify Minecraft For Windows 8 303

MojoKid writes "The backlash against Windows 8 from various developers continues, but this time a game's creator isn't just expressing discontent. Notch, the developer behind smash hit Minecraft, has declared that he won't be working with Microsoft to certify Minecraft for Windows 8. Note that this doesn't mean Minecraft won't run on Windows 8. The certification process in question is Microsoft's mandatory rules for submitting content to the Windows game store. In order to be listed there, an application must be Metro-compatible and conform to a laundry list of other conditions. The real problem with Windows 8 is that it locks ARM users into a second class experience. If you buy an x86 tablet, you can download programs from SourceForge, GitHub, or any file mirror. If you're an ARM user, you can download programs from the Microsoft store and that's it. The bifurcated permission structure is the problem, and it makes WinRT tablets categorically impossible to recommend for anyone who values the ability to install whatever software they please."

Malicious PhpMyAdmin Served From SourceForge Mirror 86

An anonymous reader writes with a bit of news about the compromised download of phpMyAdmin discovered on an sf.net mirror yesterday: "A malicious version of the open source Web-based MySQL database administration tool phpMyAdmin has been discovered on one of the official mirror sites of SourceForge, the popular online code repository for free and open source software. The file — phpMyAdmin-3.5.2.2-all-languages.zip — was modified to include a backdoor that allowed attackers to remotely execute PHP code on the server running the malicious version of phpMyAdmin." The Sourceforge weblog has details. Someone compromised a mirror (since removed from rotation of course) around September 22nd. Luckily, only around 400 people grabbed the file before someone caught it.

Adobe Releases New Openly Licensed Coding Font 136

tqft writes "From the sourceforge page: 'Source Sans is a set of monospaced OpenType fonts that have been designed to work well coding environments. This family of fonts is a complementary design to the Source Sans family.' License: Open Font License 1.1 (OFL 1.1) (both FSF and DFSG free). Hope to see it Debian (& other) repositories soon." The example text doesn't really look too much better than Inconsolata. But, hey, who can complain about more liberally licensed fonts?

Converting RSS Feeds To a Dynamic 3D Scene In 120 Lines of Code 73

descubes writes "Tao Presentations is a 3D presentation tool based on a 3D dynamic document description language. This makes it very easy for developers to create their own 3D shows, illustrate talks in an innovative way, even build small interactive 3D applications. An example included in the latest release grabs RSS feeds from a variety of sources (including Slashdot) and turns them into a 3D scene, all in real-time and in about 120 lines of code. It fetches the pictures directly from the web site and maps them on 3D shapes. And this is only a starting point. Tao Presentations can display 3D objects, drive the majority of 3D displays (including glasses-free 3D displays from Alioscopy, Philips or Tridelity), use GLSL shaders for advanced effects, and much more. Tao Presentations is free (as in beer), and the document description language is based on the free (as in speech) XL programming language."

SourceForge Allura Submitted To the Apache Software Foundation Incubator 30

rbowen writes "The software that powers the SourceForge developer tools (SourceForge is owned by the same corporate overlords as Slashdot) has been submitted to the Apache Software Foundation Incubator. The SourceForge Blog reads: 'By submitting Allura to the Apache Incubator, we hope to draw an even wider community of developers who can advance the feature set and tailor the framework to their needs. With the flexibility and extensibility Allura allows, developers are free to use any number of the popular source code management tools, including: Git, SVN, or Mercurial. We are indeed willing to turn our own open source platform into a tool that everyone can use and extend, and we believe Apache is the best place to steward the process.'"

Why Do Programming Languages Succeed Or Fail? 201

magicmat writes "UC Berkeley EECS graduate researchers Leo Meyerovich and Ari Rabkin have compiled an interesting data set on the sociological aspects of programming language usage and adoption. 'Socio-PLT' is the result: compiling survey results from Berkeley's recent 'software engineering' massive online open course, SourceForge, and two years of The Hammer Principle online surveys, they have discovered some interesting phenomenon about what we, as programmers think about our languages, and why we use them. You can head over and explore the data yourself using cool interactive visualizations, and even fill out a survey yourself to have your say."

Comparing R, Octave, and Python for Data Analysis 61

Here is a breakdown of R, Octave and Python, and how analysts can rely on open-source software and online learning resources to bring data-mining capabilities into their companies. The article breaks down which of the three is easiest to use, which do well with visualizations, which handle big data the best, etc. The lack of a budget shouldn't prevent you from experiencing all the benefits of a top-shelf data analysis package, and each of these options brings its own set of strengths while being much cheaper to implement than the typical proprietary solutions.

Sigrok: An Open Source Logic Analyzer 42

Uwe Hermann today announced the availability of sigrok, one of the first Open Source logic analyzers. Tired of being tied to Windows and proprietary software with limited features, in late 2010 he began work on flosslogic, which, after discovering Bert Vermeulen was also working on similar software, became sigrok. From the article: "Thus, the goal was to write a portable, GPL'd, software that can talk to many different logic analyzers via modules/plugins, supports many input/output formats, and many different protocol decoders. ... Currently supported hardware includes: Saleae Logic, CWAV USBee SX, Openbench Logic Sniffer (OLS), ZEROPLUS Logic Cube LAP-C, ASIX Sigma/Sigma2, ChronoVu LA8, and others." Their wiki has a list of supported protocols as well. You can grab the source over at SourceForge.
