Tiniest Linux COM Yet? 76

DeviceGuru writes: "An open-spec COM that runs OpenWRT Linux on a MIPS-based Ralink RT5350 SoC has won its Indiegogo funding. The $20, IoT-focused VoCore measures 25 x 25mm. How low can you go? Tiny computer-on-modules (COMs) for Internet of Things (IoT) applications are popping up everywhere, with recent, Linux-ready entries including Intel's Atom or Quark-based Edison, Ingenic's MIPS/Xburst-based Newton, Acme Systems's ARM9/SAM9G25 based Arrietta G25, and SolidRun's quad-core i.MX6-based MicroSOM. Now, an unnamed Chinese startup has raised over six times its $6,000 Indiegogo funding goal for what could be the smallest, cheapest Linux COM yet."

Become a Linux Kernel Hacker and Write Your Own Module 143

M-Saunders (706738) writes "It might sound daunting, but kernel hacking isn't a mysterious black art reserved for the geekiest of programmers. With a bit of background knowledge, anyone with a grounding in C can implement a new kernel module and understand how the kernel works internally. Linux Voice explains how to write a module that creates a new device node, /dev/reverse, that reverses a string when it's written to it. Sure, it's not the most practical example in the world, but it's a good starting point for your own projects, and gives you an insight into how it all fits together."

Mesa 10.2 Will Feature Better Adreno Driver, OpenMAX, Cherryview Support 21

Via Phoronix comes news that Mesa 10.2 will be released in a few days with several interesting new features. Highlights include OpenGL 2.1 support for Freedreno (the driver for the Qualcomm graphics chips), video encoding and decoding on GCN Radeons using the new OpenMAX state tracker, and initial support for Intel's upcoming Cherryview Atom SoC. Progress is being made toward OpenGL 4 support, and the llvmpipe software rasterizer finally supports OpenGL 3.2. The release won't feature a few things: the Intel Sandybridge driver still does not support OpenGL 3.3, the R9 290 Radeons are still not working (despite claims by AMD a couple of years ago that cards starting with the Radeon 8000 series would be supported by the Free Software driver at hardware release time), and OpenCL support is still experimental.

Valve In-Home Game Streaming Supports Windows, OS X & Linux 106

MojoKid (1002251) writes "Valve has today pushed out a new update to its Steam client on all three of the major OSes that finally takes In-home Game-Streaming out of beta. Similar to NVIDIA's GameStream, which streams native gameplay from a GeForce-equipped PC to the NVIDIA SHIELD, Valve's solution lets you stream from one PC to another, regardless of which OS it's running. What this means is you could have a SteamOS-based PC in your living-room, which is of course Linux-based, and stream games from your Windows PC in another room which ordinarily would never run under Linux. Likewise, you could stream a game from a Windows PC to an OS X machine, or vice versa."

The Linux Foundation and edX Team Up for Intoduction to Linux Class 74

An anonymous reader writes "The Linux Foundation has teamed up with MOOC provider edX to teach an introduction to Linux class. Quoting the course description: 'This course explores the various tools and techniques commonly used by Linux programmers, system administrators and end users to achieve their day-to-day work in a Linux environment. It is designed for experienced computer users who have limited or no previous exposure to Linux, whether they are working in an individual or Enterprise environment.' The course begins on August 1st. In addition to the free version of the course, a verified track is available for students who want a credential with more weight (for a nominal price)." Update: As many have pointed out Linus just did an intro for the class. Headline corrected accordingly.

Robyn Bergeron Stepping Down As Fedora Project Leader 53

darthcamaro writes: "Red Hat's Fedora Linux Project Leader, Robyn Bergeron, has announced that she is leaving her role. Bergeron became Fedora Project Leader in February of 2012 and has presided over one of the busiest periods for Fedora ever. Fedora is now moving to a new model for Fedora 21, with separate desktop, cloud and server products. 'The community has now gotten to the point where it's not a one-size-fits-all product anymore,' Bergeron said."

OpenStack: the Open Source Cloud That Vendors Love and Users Are Ignoring 99

Brandon Butler writes: "OpenStack has no shortage of corporate backers. Rackspace, Red Hat, IBM, Dell, HP, Cisco and many others have hopped on board. But many wonder, after four years, shouldn't there be more end users by this point? 'OpenStack backers say this progression is completely normal. Repeating an analogy many have made, Paul Cormier, president of products and technology for Red Hat, says OpenStack’s development is just like the process of building up Linux. This time the transition to a cloud-based architecture is an even bigger technological transformation than replacing proprietary operating systems with Linux. "It’s where Linux was in the beginning," he says about OpenStack's current status. "Linux was around for a while before it really got adopted in the enterprise. OpenStack is going through the same process right now."'"
It's funny.  Laugh.

Video Linux Sucks (Video) 293

How do we know Linux sucks? Because Bryan Lunduke says so. How did he become a Linux authority? By using Linux, of course. He has also written a kids Linux book, Linux for Hank, and a grown-up Linux book, Linux is Badass. But wait! That's not all! Bryan is also one of the people behind the infamous Bad Voltage podcast.

And now, for something slightly different: In moments of weakness, Bryan admits that maybe Linux suckage isn't total, and Linux may have a good point or two and maybe some of the suckage could be removed. Zounds! Is that possible? Watch our video chat with Bryan (and/or read the transcript) and see. Or watch the entire 44 minute speech he gave at the 2014 LinuxFest Northwest, which was the 5th (or maybe 6th) "Linux Sucks" speech he's given at LFNW. That makes this a tradition, not just a speech. So if you find yourself in or near Bellingham, Washington, in 2039 you might want to pop in and see if Bryan is still updating his "Linux Sucks" speech. He'll be the geezer hobbling to the front of the room with help from his AutoCane, a device sure to be developed between now and then -- which will no doubt run Linux. (Alternate video link)

Tux3 File System Could Finally Make It Into the Mainline Linux Kernel 121

An anonymous reader writes "The Tux3 file-system that's been in development since 2008 as the public replacement to the patent-blocked Tux2 file-system is now under review for inclusion into the Linux kernel. Tux3 tries to act as a 'light, tight, modern file-system. We offer a fresh approach to some ancient problems,' according to its lead developer, Daniel Phillips. Tux3 strives for minimal resource consumption but lacks enterprise-grade reliability at this point. Tux3, at the end of the day, tries to be 'robust, fast, and simple' with the Linux FS reportedly being as fast as other well known file-systems. Details on the project are at Tux3.org."

Why Should Red Hat Support Competitors' Software? 111

colinneagle (2544914) writes "The Wall Street Journal recently reported that, based on documents it reviewed, Red Hat "has chosen not to provide support to its commercial Linux customers if they use rival versions of OpenStack." But the big question is: Why would customers have expected that in the first place? Gartner analyst Lydia Leong told Network World that Red Hat isn't really doing anything wrong here. Customers shouldn't have an expectation that Red Hat would support competitors' software. "The norm would be to expect that non-Red Hat software is treated like any other third-party software," Leong says. If Red Hat has done anything wrong, it's that it has not clearly articulated its positioning and support for non-Red Hat OpenStack distros. Red Hat did not immediately respond to a question asking for a clarification on its support policy. The complication in all this comes from the fact that OpenStack is an open source project and there are misconceived notions that all OpenStack clouds are interoperable with one another. But Leong says just because OpenStack is open source doesn't change the expectations around vendors supporting competitors' products."

5-Year-Old Linux Kernel Bug Fixed 127

rastos1 sends in a report about a significant bug fix for the Linux kernel (CVE-2014-0196). "'The memory-corruption vulnerability, which was introduced in version 2.6.31-rc3, released no later than 2009, allows unprivileged users to crash or execute malicious code on vulnerable systems, according to the notes accompanying proof-of-concept code available here. The flaw resides in the n_tty_write function controlling the Linux pseudo tty device. 'This is the first serious privilege escalation vulnerability since the perf_events issue (CVE-2013-2049) in April 2013 that is potentially reliably exploitable, is not architecture or configuration dependent, and affects a wide range of Linux kernels (since 2.6.31),' Dan Rosenberg, a senior security researcher at Azimuth Security, told Ars in an e-mail. 'A bug this serious only comes out once every couple years.' ... While the vulnerability can be exploited only by someone with an existing account, the requirement may not be hard to satisfy in hosting facilities that provide shared servers, Rosenberg said."

The Man Behind Munich's Migration of 15,000 PCs From Windows To Linux 264

An anonymous reader writes "It's one of the biggest migrations in the history of Linux, and it made Steve Ballmer very angry: Munich, in southwest Germany, has completed its transition of 15,000 PCs from Windows to Linux. It has saved money, fueled the local economy, and improved security. Linux Voice talked to the man behind the migration: 'One of the biggest aims of LiMux was to make the city more independent. Germany’s major center-left political party is the SPD, and its local Munich politicians backed the idea of the city council switching to Linux. They wanted to promote small and medium-sized companies in the area, giving them funding to improve the city’s IT infrastructure, instead of sending the money overseas to a large American corporation. The SPD argued that moving to Linux would foster the local IT market, as the city would pay localcompanies to do the work.' (Linux Voice is making the PDF article free [CC-BY-SA] so that everyone can send it to their local councilors and encourage them to investigate Linux)."

Ask Slashdot: Practical Alternatives To Systemd? 533

First time accepted submitter systemDead (3645325) writes "I looked mostly with disinterest at Debian's decision last February to switch to systemd as the default init system for their future operating system releases. The Debian GNU/Linux distribution is, after all, famous for allowing users greater freedom to choose what system components they want to install. This appeared to be the case with the init system, given the presence of packages such as sysvinit-core, upstart, and even openrc as alternatives to systemd.

Unfortunately, while still theoretically possible, installing an alternative init system means doing without a number of useful, even essential system programs. By design, systemd appears to be a full-blown everything-including-the-kitchen-sink solution to the relatively simple problem of starting up a Unix-like system. Systemd, for example, is a hard-coded dependency for installing Network Manager, probably the most user-friendly way for a desktop Linux system to connect to a wireless or wired network. Just this week, I woke up to find out that systemd had become a dependency for running PolicyKit, the suite of programs responsible for user privileges and permissions in a typical Linux desktop.

I was able to replace Network Manager with connman, a lightweight program originally developed for mobile devices. But with systemd infecting even the PolicyKit framework, I find myself faced with a dilemma. Should I just let systemd take over my entire system, or should I retreat to my old terminal-based computing in the hope that the horde of the systemDead don't take over the Linux kernel itself?

What are your plans for working with or working around systemd? Are there any mainstream GNU/Linux distros that haven't adopted and have no plans of migrating to systemd? Or is migrating to one of the bigger BSD systems the better and more future-proof solution?"

Video Jon 'maddog' Hall On the Future of Free Software (Video) 47

You know who maddog is, right? He's one of our favorite speakers on what we might call the Linux/FOSS circuit. So you know, despite the Noel Coward song that says, "Mad Dogs and Englishmen go out in the midday sun," Jon prefers shade much of the time when he's in a tropical climate, based on personal observations at Linux conferences in Florida and Hawaii. But sun or shade, maddog is an eloquent and interesting speaker. We'd like to take you all to hear him in person, but we can't, so this video is the next best thing. (Alternate Video Link)

US Military Drones Migrating To Linux 197

DeviceGuru (1136715) writes "Raytheon is switching its UAV control system from Solaris to Linux for U.S. military drones, starting with a Northrop Grumman MQ-8C Fire Scout helicopter. Earlier this month Raytheon entered into a $15.8 million contract with the U.S. Navy to upgrade Raytheon's control systems for unmanned aerial vehicles (UAVs), according to a recent Avionics Intelligence report. The overhaul is designed to implement more modern controls to help ground-based personnel control UAVs. Raytheon's tuxified version of its Vertical Takeoff and Landing Unmanned Air Vehicle Tactical Control System (TCS) will also implement universal UAV control qualities. As a result the TCS can be used in in all U.S. Navy, Air Force, Army, and Marine Corps UAVs that weigh at least 20 pounds. By providing an open standard, the common Linux-based platform is expected to reduce costs by limiting the types of UAV control systems that need to be built and maintained for each craft."

Video Another Year of LinuxFest Northwest (Video) 12

We last interviewed LinuxFest volunteer Jakob Perry in January, 2013, when he and the rest of the crew that makes this event happen were gearing up for their 14th version of this outstanding regional Linux/FOSS conference. Now they've gotten through LinuxFest 15, which makes this one of the longest-lasting Linux shows around. And Jakob is still helping to put it together, as he has since he was a teenager. Since he's been with LinuxFest Northwest since the beginning, this gives him some serious longevity cred, especially when you realize that he has been volunteering with LFNW since he was 15 years old -- and hasn't seemed to lose a bit of his enthusiasm in all that time.

Valve Sponsors Work To Greatly Speed-Up Linux OpenGL Game Load Times 202

An anonymous reader writes "Valve Software has sponsored some interesting improvements developed by LunarG for the Mesa OpenGL library on Linux for deferred and threaded GLSL shader compilation. What these changes mean for users of the open-source Linux graphics drivers when running their favorite games is that OpenGL games now load a lot faster. As an example, the time from starting Dota 2 until the time actually being within the game is reduced by about 20 seconds on an Intel system. While Direct3D has offered similar functionality for a while, OpenGL has not, which has given it a bad reputation with regard to game load times until all shaders are compiled and cached — fortunately it's now addressed for OpenGL if using the Mesa Linux graphics drivers on a supported game."

Linus Torvalds Receives IEEE Computer Pioneer Award 141

mikejuk (1801200) writes "Linus Torvalds, the 'man who invented Linux' is the 2014 recipient of the IEEE Computer Society's Computer Pioneer Award, '[f]or pioneering development of the Linux kernel using the open-source approach.' According to Wikipedia, Torvalds had wanted to call the kernel he developed Freax (a combination of 'free,' 'freak,' and the letter X to indicate that it is a Unix-like system), but his friend Ari Lemmke, who administered the FTP server it was first hosted for download, named Torvalds' directory linux. In some ways Git can be seen as his more important contribution — but as it dates from 2005 it is outside the remit of the IEEE Computer Pioneer award."
