Linux Kernel Running In JavaScript Emulator With Graphics and Network Support 177

New submitter warmflatsprite writes "It seems that there have been a rash of JavaScript virtual machines running Linux lately (or maybe I just travel in really weird circles). However until now none of them had network support, so they weren't too terribly useful. Sebastian Macke's jor1k project uses asm.js to produce a very fast emulation of the OpenCores OpenRISC processor (or1k) along with a HTML5 canvas framebuffer for graphics support. Recently Ben Burns contributed an emulated OpenCores ethmac ethernet adapter to the project. This sends ethernet frames to a gateway server via websocket where they are switched and/or piped into TAP virtual ethernet adapter. With this you can build whatever kind of network appliance you'd like for the myriad of fast, sandboxed VMs running in your users' browsers. For the live demo all VMs connect to a single private LAN (subnet 10.5.0.0/16). The websocket gateway also NATs traffic from that LAN out to the open Internet."

Linux 3.12 Released, Linus Proposes Bug Fix-Only 4.0 274

An anonymous reader writes "Linus Torvalds announced the Linux 3.12 kernel release with a large number of improvements through many subsystems including new EXT4 file-system features, AMD Berlin APU support, a major CPUfreq governor improvement yielding impressive performance boosts for certain hardware/workloads, new drivers, and continued bug-fixing. Linus also took the opportunity to share possible plans for Linux 4.0. He's thinking of tagging Linux 4.0 following the Linux 3.19 release in about one year and is also considering the idea of Linux 4.0 being a release cycle with nothing but bug-fixes. Does Linux really need an entire two-month release cycle with nothing but bug-fixing? It's still to be decided by the kernel developers."

Intel Open-Sources Broadwell GPU Driver & Indicates Major Silicon Changes 103

An anonymous reader writes "Intel shipped open-source Broadwell graphics driver support for Linux this weekend. While building upon the existing Intel Linux GPU driver, the kernel driver changes are significant in size for Broadwell. Code comments from Intel indicate that these processors shipping in 2014 will have "some of the biggest changes we've seen on the execution and memory management side of the GPU" and "dwarf any other silicon iteration during my tenure, and certainly can compete with the likes of the gen3->gen4 changes." Come next year, Intel may now be able to better take on AMD and NVIDIA discrete graphics solutions."

Tech Titans Oracle, Red Hat and Google To Help Fix Healthcare.gov 404

wjcofkc writes "The United States Government has officially called in the calvary over the problems with Healthcare.gov. Tech titans Oracle, Red Hat and Google have been tapped to join the effort to fix the website that went live a month ago, only to quickly roll over and die. While a tech surge of engineers to fix such a complex problem is arguably not the greatest idea, if you're going to do so, you might as well bring in the big guns. The question is: can they make the end of November deadline?"

Debian To Replace SysVinit, Switch To Systemd Or Upstart 362

An anonymous reader writes "Debian has been one of the last holdouts using SysVinit over a modern init system, but now after much discussion amongst Debian developers, they are deciding whether to support systemd or Upstart as their default init system. The Debian technical committee has been asked to vote on which init system to use, which could swing in favor of using Upstart due to the Canonical bias present on the committee."

Ask Slashdot: Best Cross-Platform (Linux-Only) Audio Software? 223

blogologue writes "I have played the guitar for some years now, and these days I think it's good therapy to be creative with music, learning the piano and singing as well. So far I've been using Audacity as the tool to compose improvisations and demos. I haven't done much audio work before, but it is already becoming too limited for my needs. Being a Linux-fanboy since the mid-nineties, I'm now looking for a good audio processing/editing/enhancing setup that can run on different platforms, the most important being Linux. Are there any suggestions for Open Source or proprietary audio editing software that run on Linux?"

Torvalds: Free OS X Is No Threat To Linux 314

jfruh writes "Apple is now offering upgrades to the latest version of OS X for free. When Linux inventor Linus Torvalds was asked whether this threatened Linux (presumably by someone who had only a passing knowledge of all the things 'free' can mean when applied to software) it gave him an opportunity for a passionate defense of open source. Torvalds also says that he'll keep programming until it gets 'not interesting,' which hasn't happened yet." The newest version of OS X may be gratis for Apple hardware buyers, but it's notably far from the original, (literally) un-branded sense of "mavericks."

Torvalds: SteamOS Will 'Really Help' Linux On the Desktop 304

nk497 writes "Linus Torvalds has welcomed the arrival of Valve's Linux-based platform, SteamOS, and said it could boost Linux on desktops. The Linux creator praised Valve's 'vision' and suggested its momentum would force other manufacturers to take Linux seriously — especially if game developers start to ditch Windows. Should SteamOS gain traction among gamers and developers, that could force more hardware manufacturers to extend driver support beyond Windows. That's a sore point for Torvalds, who slammed Nvidia last year for failing to support open-source driver development for its graphics chips. Now that SteamOS is on the way, Nvidia has opened up to the Linux community, something Torvalds predicts is a sign of things to come. 'I'm not just saying it'll help us get traction with the graphics guys,' he said. 'It'll also force different distributors to realize if this is how Steam is going, they need to do the same thing because they can't afford to be different in this respect. They want people to play games on their platform too.'"

Ubuntu Touch On a Nexus 7: "Almost Awesome" 116

colinneagle writes "I installed Ubuntu Touch "1.0" on my first-generation Nexus 7 tablet and have been using it as my main tablet system for the last four days. Here's how it went. First off, the installation was surprisingly painless. I followed the official instructions and didn't encounter a single problem. That being said, the installation is really geared toward software developers, power users or people already comfortable on a Linux command line. If you're not in one of those categories, I recommend holding off for the time being. Once installed, Ubuntu Touch booted up rather quickly — in only just a few seconds (a fair bit faster than Android 4.x on the same tablet). And, immediately, I was presented with a short tutorial that appears the first time the system is booted, which, I might add, has got to be one of the slickest, least annoying tutorials I've seen. But... there were problems. The battery life was, to put it mildly, terrible. Performance has been mixed, and the OS was prone to what I call 'The Pulsating Seizure Feature' a few dozen times over the weekend. In a nutshell: launching apps (and, occasionally, moving between apps) can cause the device to freeze and begin flashing the screen rapidly."

Freedreno Graphics Driver Gets PRIME, Render Node Support 14

Via Phoronix comes news that the new DRM driver for the Freedreno driver for Qualcomm Snapdragon Adreno graphics is gaining a few new features in Linux 3.13: "After a year of working on the 'Freedreno' Gallium3D user-space driver and getting that up to speed for Qualcomm Adreno/Snapdragon support, for the past few months he's been working on a complementary kernel driver rather than relying upon Qualcomm's Android-focused kernel layer. ... The work that Rob has ready for Linux 3.13 with this Qualcomm DRM graphics driver is DRI PRIME support, support for render nodes, updated header files, plane support, and a couple of other changes."

Your Next Network Operating System Is Linux 192

jrepin writes "Everywhere you look, change is afoot in computer networking. As data centers grow in size and complexity, traditional tools are proving too slow or too cumbersome to handle that expansion. Dinesh Dutt is Chief Scientist at Cumulus Networks. Cumulus has been working to change the way we think about networks altogether by dispensing with the usual software/hardware lockstep, and instead using Linux as the operating system on network hardware. In this week's New Tech Forum, Dinesh details the reasons and the means by which we may see Linux take over yet another aspect of computing: the network itself."

NFTables To Replace iptables In the Linux Kernel 235

An anonymous reader writes "NFTables is queued up for merging into the Linux 3.13 kernel. NFTables is a four-year-old project by the creators of Netfilter to write a new packet filtering / firewall engine for the Linux kernel to deprecate iptables (though it now offers an iptables compatibility layer too). NFTables promises to be more powerful, simpler, reduce code complication, improve error reporting, and provide more efficient handling of packet filter rules. The code was merged into net-next for the Linux 3.13 kernel. Iptables will still be present until NFTables is finished, but it is possible to try it out now. LWN also has a writeup on NFTables."

USS Zumwalt — a Guided Missile Destroyer Running On Linux 229

New submitter SanDogWeps writes "Sean Gallagher over at Ars Technica reports that when the U.S.S. Zumwalt (DDG 1000) puts to sea later this year, it will be different from any other ship in the Navy's fleet in many ways. The $3.5 billion ship is designed for stealth, survivability, and firepower, and it's packed with advanced technology. And at the heart of its operations is a virtual data center powered by off-the-shelf server hardware, various flavors of Linux, and over 6 million lines of software code. From the article: 'Called the Common Display System, or CDS (pronounced as "keds" by those who work with it), the three-screen workstations in the operations center are powered by a collection of quad-processor Intel motherboards in an armored case, which gives new meaning to the nautical phrase "toe buster." Even the commanding officer's and executive officer's chairs on the bridge have CDS workstations built-in. Each CDS system runs multiple LynxOS-based Linux virtual machines, which can run on various networks partitioned by security level and purpose. '"

Ubuntu, Kubuntu 13.10 Unleashed 143

llebeel writes "Canonical announced its free Ubuntu 13.10 Linux operating system (OS) release, on the same day as Microsoft's remedial Windows 8.1 service pack update. We speak to Canonical founder and Ubuntu creator Mark Shuttleworth who tells us what to expect." Adds reader jrepin: "Kubuntu Linux 13.10 has just been released and is available for download. It comes with KDE Software Compilation 4.11, a new application for discovering and installing software, a simpler way to manage your system users. and a new Network Manager applet gives a simpler UI for connecting to a range of network types. You can now setup Wifi networking from the installer making it easier to install updates and extra packages during the install." ZDNet has a fairly tepid review of the incremental rather than startling improvements of the new release, and notes "Ubuntu 14.04 LTS, due for release on 17 April next year, will now perhaps come as even more of a shock if its promised big changes are fully realised."

How To Attend Next Week's Robotics Show Robotically 38

DeviceGuru writes "Suitable Technologies is offering $50 rentals of its Beam mobile telepresence robot, allowing 50 robotics enthusiasts to remotely attend the RoboBusiness conference in Santa Clara, Calif. on Oct. 23-25. The Ubuntu- and ROS-based Beam will be available to the first 50 applicants, letting them explore the show at up to 1.5 meters/sec and interact with others via video conferencing. The bots will be allowed everywhere on the show floor as well as in conference rooms, and the show will be open late to accommodate remote users from distant time zones. The Beam is a good choice for remotely exploring conferences, saving users the cost and time of traveling to an event, says Suitable Tech; for example, RoboBusiness registration costs $1,595, not including hotel and travel. A list of the conference's keynotes, which include one by Christ Urmson, director of Google's Self-Driving Cars project, is available here."

Linux RNG May Be Insecure After All 240

Okian Warrior writes "As a followup to Linus's opinion about people skeptical of the Linux random number generator, a new paper analyzes the robustness of /dev/urandom and /dev/random . From the paper: 'From a practical side, we also give a precise assessment of the security of the two Linux PRNGs, /dev/random and /dev/urandom. In particular, we show several attacks proving that these PRNGs are not robust according to our definition, and do not accumulate entropy properly. These attacks are due to the vulnerabilities of the entropy estimator and the internal mixing function of the Linux PRNGs. These attacks against the Linux PRNG show that it does not satisfy the "robustness" notion of security, but it remains unclear if these attacks lead to actual exploitable vulnerabilities in practice.'" Of course, you might not even be able to trust hardware RNGs. Rather than simply proving that the Linux PRNGs are not robust thanks to their run-time entropy estimator, the authors provide a new property for proving the robustness of the entropy accumulation stage of a PRNG, and offer an alternative PRNG model and proof that is both robust and more efficient than the current Linux PRNGs.

Battlefield Director: Linux Only Needs One 'Killer' Game To Explode 410

dryriver writes with an except from Polygon's interview with DICE creative directory Lars Gustavsson, who says it would only take one "killer" game for Linux to break into mainstream gaming (something some would argue it already has): "We strongly want to get into Linux for a reason," Gustavsson said. "It took Halo for the first Xbox to kick off and go crazy — usually, it takes one killer app or game and then people are more than willing [to adopt it] — it is not hard to get your hands on Linux, for example, it only takes one game that motivates you to go there." "I think, even then, customers are getting more and more convenient, so you really need to convince them how can they marry it into their daily lives and make an integral part of their lives," he explained, sharing that the studio has used Linux servers because it was a "superior operating system to do so." Valve's recently announced Steam OS and Steam Machines are healthy for the console market, Gustavsson said when asked for his opinion on Valve's recent announcements."

PengPod Crowdfunding a Tablet Made With OS-Switching In Mind 93

PengPod is running a crowdfunder to create a GNU Linux/Android tablet, the PengPod 1040. This is their second such product; the first was mentioned on Slashdot last year. PengPod has pledged to make all source and tools used to build the images available, so users can build their own OS top to bottom to guarantee that it's free of NSA tracking. The PengPod has previously found some success as a low-cost touch platform for industrial/commercial control systems and is partnered with ViewTouch, the original inventors of the graphical POS to offer PengPod1040s as restaurant register systems. The feature that the developers seem keenest to emphasize is that the PengPod is built to run conventional desktop Linux distros without special hacking required; Android is the default OS, but it's been tested with several others (including Ubuntu Touch) listed on their Indiegogo page.

Google Offers Cash For Security Fixes To Linux and Other FOSS Projects 94

jrepin writes "Google is offering rewards as high as $3,133.70 for software updates that improve the security of OpenSSL, OpenSSH, BIND, and several other open-source packages that are critical to the stability of the Internet. The program announced Wednesday expands on Google's current bug-bounty program, which pays from $500 to $3,133.70 to people who privately report bugs found in the company's software and Web properties." Google isn't the only company that sees the value in rewarding those who find security problems: Microsoft just paid British hacker James Forshaw $100,000 for finding a serious security flaw in Windows 8.1.
