Video Louis Suarez-Potts Talks About Making Money with FOSS (Video) 33

Louis Suarez-Potts has been community manager for OpenOffice since it was sponsored by Sun Microsystems. He's still working with OpenOffice now that it's under the Apache Foundation umbrella. He also has a business going, along with several other long-time Free and Open Source boosters, called Age of Peers. They say it's "a collective forum for consultants, practitioners and boutique agencies, to collaborate on a bigger picture. We mix these ingredients in an organization built to foster collaboration, and harness creative cooperation into powerful new ideas." The company is focused on Open Source developers and companies, and often doesn't charge startups or individual developers for their services. They will be doing a live Google Hangout interview on March 5 that might give you some ideas about how to start, manage, and market an Open Source project -- even if you have no money to spend, which many people who have good ideas do not, at least when they get started.

Plan 9 From Bell Labs Operating System Now Available Under GPLv2 223

TopSpin writes "Alcatel-Lucent has authorized The University of California, Berkeley to 'release all Plan 9 software previously governed by the Lucent Public License, Version 1.02 under the GNU General Public License, Version 2.' Plan 9 was developed primarily for research purposes as the successor to Unix by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. Plan 9 has subsequently emerged as Inferno, a commercially supported derivative, and ports to various platforms, including a recent port to the Raspberry Pi. In Plan 9, all system interfaces, including those required for networking and the user interface, are represented through the file system rather than specialized interfaces. The system provides a generic protocol, 9P, to perform all communication with the system, among processes and with network resources. Applications compose resources using union file systems to form isolated namespaces."

GNU Hurd Gets Improvements: User-Space Driver Support and More 163

jones_supa writes "At FOSDEM 2014 some recent developments of GNU Hurd were discussed (PDF slides). In the name of freedom, GNU Hurd has now the ability to run device drivers from user-space via the project's DDE layer. Among the mentioned use-cases for the GNU Hurd DDE are allowing VPN traffic to just one application, mounting one's own files, redirecting a user's audio, and more flexible hardware support. You can also run Linux kernel drivers in Hurd's user-space. Hurd developers also have working IDE support, X.Org / graphics support, an AHCI driver for Serial ATA, and a Xen PV DomU. Besides the 64-bit support not being in a usable state, USB and sound support is still missing. As some other good news for GNU Hurd, around 79% of the Debian archive is now building for GNU Hurd, including the Xfce desktop (GNOME and KDE soon) and Firefox web browser."

LLVM & GCC Compiler Developers To Begin Collaborating 279

An anonymous reader writes "While RMS is opposed to LLVM over its BSD-like license rather than the GPL, LLVM/Clang and GCC developers have agreed to try to start cooperating in an "open compiler initiative" to jointly tackle common issues that plague both compilers and issues that can be better served by working together rather than creating fragmentation between the two popular open-source compilers."

Adobe Flash Remote Code Execution Flaw Exploited In the Wild 187

An anonymous reader writes "Adobe has released an emergency patch for a critical vulnerability affecting Flash Player for Windows, Linux, and OS X, the exploitation of which can result in an attacker gaining remote control of the victims' systems. The flaw is being actively exploited in the wild, but apart from crediting its discovery to researchers Alexander Polyakov and Anton Ivanov of Kaspersky Labs, no details about the ongoing attack has been shared." They even updated the explicitly unsupported NPAPI GNU/Linux version.

FSF's Richard Stallman Calls LLVM a 'Terrible Setback' 1098

An anonymous reader writes "Richard Stallman has called LLVM a terrible setback in a new mailing list exchange over GCC vs. Clang. LLVM continues to be widely used and grow in popularity for different uses, but it's under a BSD-style license rather than the GPL. RMS wrote, 'For GCC to be replaced by another technically superior compiler that defended freedom equally well would cause me some personal regret, but I would rejoice for the community's advance. The existence of LLVM is a terrible setback for our community precisely because it is not copylefted and can be used as the basis for nonfree compilers — so that all contribution to LLVM directly helps proprietary software as much as it helps us.'"

Valve Offers Free Subscription To Debian Developers: Paying It Forward 205

sfcrazy writes "Valve Software, the makers of Steam OS, is already winning praise from the larger free and open source community – mainly because of their pro-community approach. Now the company is 'giving back' to Debian by offering free subscription to Debian developers. This subscription will offer full access to current and future games produced by Valve. Since Steam OS is based on Debian GNU/Linux it's a nice way for Valve to say 'thank you' to Debian developers."

Valve Working on GNU/Linux Native Open Source OpenGL Debugger 88

jones_supa writes "OpenGL debugging has always lagged behind DirectX, mainly because of the excellent DX graphics debugging tools shipping with Visual Studio and GL being left with APITrace. Valve's Linux initiatives are making game companies to think about OpenGL, and the video game company wants to create a good open source OpenGL debugger to improve the ecosystem. AMD and Nvidia have already expressed interest in helping them out. Valve has been developing VOGL mostly on Ubuntu-based distributions under Qt Creator. The software currently supports tracing OpenGL 1.0 through 3.3 (core and compatibility), and is expected to eventually support OpenGL 4.x. Many more details on VOGL can be found at Valve's Rich Geldreich's blog." This looks much nicer than BuGLe. Valve is using Mercurial for version control and they plan to throw it up on bitbucket under an unspecified open source license soon. It works with clang and gcc, but debugging with gcc is currently very slow (hopefully something that can be fixed once the source is available and the gcc hackers can see what's going on). The tracer's internal binary log format can be converted into JSON for use with other tools as well.

GNU Guile Scheme Gets a Register VM and CPS-Based IL 42

In late November, Andy Wingo pushed a new register VM to Guile's (the GNU implementation of the Scheme language) master branch. It brought a number of performance improvements, but led to a bit of a conceptual mismatch between the compiler's direct-style intermediate language and the virtual machine. Earlier this week Andy Wingo announced a new continuation-passing style intermediate language for Guile. From the article: "To recap, we switched from a stack machine to a register machine because, among other reasons, register machines can consume and produce named intermediate results in fewer instructions than stack machines, and that makes things faster. To take full advantage of this new capability, it is appropriate to switch at the same time from the direct-style intermediate language (IL) that we had to an IL that names all intermediate values. ... In Guile I chose a continuation-passing style language. ... Guile's CPS language is composed of terms, expressions, and continuations. It was heavily inspired by Andrew Kennedy's 'Compiling with Continuations, Continued' paper. ... The optimizations I have currently implemented for CPS are fairly basic. Contification was tricky. One thing I did recently was to make all non-tail $call nodes require $kreceive continuations; if, as in the common case, extra values were unused, that was reflected in an unused rest argument. This required a number of optimizations to clean up and remove the extra rest arguments for other kinds of source expressions: dead-code elimination, the typical beta/eta reduction, and some code generation changes." The article describes the CPS language provided by Guile and explains the reasons behind choosing CPS over SSA or A-Normal Form. The Guile manual contains draft documentation. The new VM and Intermediate Language will be released with Guile 2.2, which should be out later this year.

Coca-Cola Reserves a Massive Range of MAC Addresses 371

An anonymous reader writes "GNU MacChanger's developer has found by chance that The Coca-Cola company got a range of MAC addresses allocated at the OUI, the IEEE Registration Authority in charge of managing the MAC addresses spectrum. What would Coca-Cola want around 16 million MAC addresses reserved? What are they planning to use them for? Could this part of a strategy around the Internet-of-things concept?"

Emacs Needs To Move To GitHub, Says ESR 252

hypnosec writes "Eric S. Raymond, co-founder of the Open Source Initiative, has recommended that Emacs should move to another version control system like GitHub, as bzr is dying. In an email, Raymond highlighted the key reasons why he believes that Emacs should move. Raymond said that bzr is moribund; its dev list has flatlined; and most of Canonical's in-house projects have already abandoned bzr and moved to GitHub. ESR believes that bzr's codebase is sufficiently mature to be used as a production tool, but he does mention that continuing to use the revision control system will have 'social and signaling effects damaging to Emacs's prospects.'" Update: 01/06 20:50 GMT by U L : ESR did not suggest Github the proprietary hosting platform for git, but rather git the version control system. Which is actually already available on Savannah (the bazaar repository is automatically synced with the git repository).

Prince of Persia Level Editor 'Apoplexy' Reaches 2.0 44

An anonymous reader writes "Last year, Jordan Mechner, the creator of the Prince of Persia video game franchise, released the long-thought-lost original Apple II source code for Prince of Persia. Today marks the release of version 2.0 of apoplexy, the free and open-source level editor of Prince of Persia for DOS. Roughly 5.5 years after its initial release, support has been added for editing Prince of Persia 2 levels in both GNU/Linux and Windows. The game has its 25th anniversary next year, but the original trilogy only has a (very) small fan community. Will old games such as this also interest future generations or will they gradually lose their appeal because of technological advances?"

GNU Octave Gets a GUI 166

jones_supa writes "GNU Octave — the open source numerical computation suite compatible with MATLAB — is doing very well. The new 3.8 release is a big change, as it brings a graphical user interface, a feature which has long been requested by users. It is peppered with OpenGL acceleration and uses the super fast FLTK toolkit for widgets. The CLI interface still remains available and GNUplot is used as a fallback in cases where OpenGL or FLTK support is not available. Other changes to Octave 3.8 are support for nested functions with scoping rules, limited support for named exceptions, new regular expressions, a TeX parser for the FLTK toolkit, overhauls to many of the m-files, function rewrites, and numerous other changes and bug fixes."

Free Software Foundation Endorses a "Truly Free" Laptop 340

An anonymous reader writes "The Free Software Foundation announced today the first laptop they have been able to certify as-is that respects the user's freedoms. The laptop is free down to using Coreboot in place of a proprietary BIOS. The OS shipped on the laptop is Trisquel, the Ubuntu derived Linux OS that removes all traces of proprietary firmware, patented formats, etc. The only issue though for new customers is this endorsed laptop comes down to being a refurbished 2006 ThinkPad X60 with single or dual-core Intel CPU, 1GB+ of RAM, 60GB+ HDD, and a 1024x768 12.1-inch screen, while costing $320+ USD (200 GBP). The FSF-certified refurbished laptops are only offered for sale through the Gluglug UK shop. Are these outdated specs worth your privacy and freedom?"

Open Source In the Datacenter: It Was Never About Innovation 100

An anonymous reader writes "The secret to open source innovation, and the reason for its triumphal success, has nothing to do with the desire to innovate. It's because of the four freedoms and the level playing field (and agility) that was the end result. It's like Douglas Adams' definition of flying: you don't try to fly, you throw yourself at the ground and miss. This article explains why it was never about innovation — it was always about freedom. Quoting: 'When the forces of economics put constant downward price pressure on software, developers look for other ways to derive income. Given the choice between simply submitting to economic forces and releasing no-cost software in proprietary form, developers found open source models to be a much better deal. Some of us didn't necessarily like the mechanics of those models, which included dual licensing and using copyleft as a means of collecting ransom, but it was a model in which developers could thrive.'"

Speed Test 2: Comparing C++ Compilers On WIndows 132

Nerval's Lobster writes "In a previous posting, developer and programmer Jeff Cogswell compared a few C++ compilers on Linux. Now he's going to perform a similar set of tests for Windows. "Like all things Windows, it can get costly doing C++ development in this environment," he writes. "However, there are a couple notable exceptions" such as free and open-source cygwin, mingW, Express Versions of Visual Studio, and Embacadero. He also matched up the Intel C++ Compiler, Microsoft C++ Compiler, and the Embarcadero C++ 6.70 Compiler. He found some interesting things — for example, Intel's compiler is pretty fast, but its annoying habit of occasionally "calling home" to check licensing information kept throwing off the rests. Read on to see how the compilers matched up in his testing."

GCC 4.9 Coming With Big New Features 181

jones_supa writes "When GCC 4.9 is released in 2014 it will be coming in hot on new features with a large assortment of improvements and new functionality for the open-source compiler. Phoronix provides a recap of some of the really great features of this next major compiler release from the Free Software Foundation. For a quick list: OpenMP 4.0, Intel Cilk Plus multi-threading support, Intel Bay Trail and Silvermont support, NDS32 port, Undefined Behavior Sanitizer, Address Sanitizer, ADA and Fortran updates, improved C11 / C++11 / C++14, better x86 intrinsics, refined diagnostics output. Bubbling under are still: Bulldozer 4 / Excavator support, OpenACC, JIT compiler, disabling Java by default."

Ask Slashdot: What Makes You Uninstall Apps? 243

jones_supa writes "One of the most important measuring sticks for the success of any software is how long a user keeps it installed after first trying it. Intel has an article about some of the most common reasons users abandon software. Quoting: 'Apps that don’t offer anything helpful or unique tend to be the ones that are uninstalled the most frequently. People cycle through apps incredibly quickly to find the one that best fits their needs. ... A lot of apps have a naturally limited lifecycle; i.e., apps that are centered around a movie release or an app that tracks a pregnancy, or an app that celebrates a holiday. In addition, apps with limited functionality, for example, “lite” games that only go so far, are uninstalled once the user has mastered all the levels.' Some of the common factors they list include: lengthy forms, asking for ratings, collecting unnecessary data, user unfriendliness, unnecessary notifications and, of course, bugs. Additionally, if people have paid even a small price for the app, they are more committed to keep it installed. So, what makes you uninstall a piece of software?"

Video Red Hat Wants to be a Dominant Force in the Cloud (Video) 40

Red Hat has two primary Cloud Evangelists: Gordon Haff and Richard Morrell. Richard says this about himself: "I'm Red Hat's Cloud Security Blogger and Cloud Evangelist based in Europe. Passionate about good code and Open Hybrid Cloud. Founder of SmoothWall protecting millions of networks for 13 years globally. My blogging and my podcasting is my own editorial and does not represent the views of Red Hat..." We have known Richard since the 20th Century, so this interview has been a long time coming. In it, he talks about how Red Hat is working to become as strong in the Open Source cloud world as it already is in GNU/Linux. This interview may not "represent the views of Red Hat," but it obviously represents the views of a loyal Red Hat employee who is also a long-time Linux enthusiast.

Speed Test: Comparing Intel C++, GNU C++, and LLVM Clang Compilers 196

Nerval's Lobster writes "Benchmarking is a tricky business: a valid benchmarking tries to remove all extraneous variables in order to get an accurate measurement, a process that's often problematic: sometimes it's nearly impossible to remove all outside influences, and often the process of taking the measurement can skew the results. In deciding to compare three compilers (the Intel C++ compiler, the GNU C++ compiler (g++), and the LLVM clang compiler), developer and editor Jeff Cogswell takes a number of 'real world' factors into account, such as how each compiler deals with templates, and comes to certain conclusions. 'It's interesting that the code built with the g++ compiler performed the best in most cases, although the clang compiler proved to be the fastest in terms of compilation time,' he writes. 'But I wasn't able to test much regarding the parallel processing with clang, since its Cilk Plus extension aren't quite ready, and the Threading Building Blocks team hasn't ported it yet.' Follow his work and see if you agree, and suggest where he can go from here."
