Red Hat Strips Down For Docker 30

Posted by timothy
from the wearing-or-not-wearing-dockers dept.
angry tapir writes Reacting to the surging popularity of the Docker virtualization technology, Red Hat has customized a version of its Linux distribution to run Docker containers. The Red Hat Enterprise Linux 7 Atomic Host strips away all the utilities residing in the stock distribution of Red Hat Enterprise Linux (RHEL) that aren't needed to run Docker containers. Removing unneeded components saves on storage space, and reduces the time needed for updating and booting up. It also provides fewer potential entry points for attackers. (Product page is here.)

Valve Developed an Open-Source Intel Vulkan GPU Driver For Linux 43

Posted by timothy
from the good-news-for-a-change dept.
An anonymous reader writes For those wondering when the first graphics driver for the new Khronos Vulkan API will materialize and for what hardware, it looks like the first driver could very well be for Intel graphics and it might not be too far away. It turns out Valve developed an Intel Linux Vulkan driver to help ISVs bootstrap their new Vulkan code, with Valve planning to open-source this driver code. This is yet another reason to love Valve, especially as Intel graphics on Linux don't even support OpenGL 4 yet.

Software Freedom Conservancy Funds GPL Suit Against VMWare 158

Posted by timothy
from the this-isn't-nam-man-there-are-rules dept.
Jeremy Allison - Sam writes with this excerpt from a news release from the Software Freedom Conservancy: Software Freedom Conservancy announces today Christoph Hellwig's lawsuit against VMware in the district court of Hamburg in Hamburg, Germany. This is the regretful but necessary next step in both Hellwig and Conservancy's ongoing effort to convince VMware to comply properly with the terms of the GPLv2, the license of Linux and many other Open Source and Free Software included in VMware's ESXi products. Serge Wroclawski points out the SFC's technical FAQ about the suit. One nugget: This case is specifically regarding a combined work that VMware allegedly created by combining their own code (“vmkernel”) with portions of Linux's code, which was licensed only under GPLv2. As such, this, to our knowledge, marks the first time an enforcement case is exclusively focused on this type of legal question relating to GPL

Demand For Linux Skills Rising This Year 91

Posted by samzenpus
from the popular-kids dept.
Nerval's Lobster writes This year is shaping up as a really good one for Linux, at least on the jobs front. According to a new report (PDF) from The Linux Foundation and Dice, nearly all surveyed hiring managers want to recruit Linux professionals within the next six months, with 44 percent of them indicating they're more likely to hire a candidate with Linux certification over one who does not. Forty-two percent of hiring managers say that experience in OpenStack and CloudStack will have a major impact on their hiring decisions, while 23 percent report security is a sought-after area of expertise and 19 percent are looking for Linux-skilled people with Software-Defined Networking skills. Ninety-seven percent of hiring managers report they will bring on Linux talent relative to other skills areas in the next six months.

Linux 4.0 Getting No-Reboot Patching 124

Posted by Soulskill
from the post-your-uptimes dept.
An anonymous reader writes: ZDNet reports that the latest changes to the Linux kernel include the ability to apply patches without requiring a reboot. From the article: "Red Hat and SUSE both started working on their own purely open-source means of giving Linux the ability to keep running even while critical patches were being installed. Red Hat's program was named kpatch, while SUSE' is named kGraft. ... At the Linux Plumbers Conference in October 2014, the two groups got together and started work on a way to patch Linux without rebooting that combines the best of both programs. Essentially, what they ended up doing was putting both kpatch and kGraft in the 4.0 Linux kernel." Note: "Simply having the code in there is just the start. Your Linux distribution will have to support it with patches that can make use of it."

Linux and Multiple Internet Uplinks: a New Tool 80

Posted by Soulskill
from the fault-tolerance-for-all dept.
New submitter Alessandro Zarrilli writes: Linux has been able do multipath routing for a long time: it means being able to have routes with multiple gateways and to use them in a (weighted) round-robin fashion. But Linux is missing a tool to actively monitor the state of internet uplinks and change the routing accordingly. Without it, from a LAN perspective, it's like having a RAID-0: just one uplink goes down and all of your LAN-to-WAN traffic goes down too. Documentation and examples on the subject are lacking; existing solutions are few and deeply integrated in firewall/routing specific distributions. To address these issues, a new standalone tool was just released: Fault Tolerant Router. It also includes a complete (iptables + ip policy routing) configuration generator.

NVIDIA Fixes Old Compiz Bug 51

Posted by timothy
from the mayan-long-count dept.
jones_supa writes NVIDIA has fixed a long-standing issue in the Ubuntu Unity desktop by patching Compiz. When opening the window of a new application, it would go black or become transparent on NVIDIA hardware. There have been bug reports dating back to Ubuntu 12.10 times. The problem was caused by Compiz, which had some leftover code from a port. An NVIDIA developer posted on Launchpad and said the NVIDIA team has been looking at this issue, and they also proposed a patch. "Our interpretation of the specification is that creating two GLX pixmaps pointing at the same drawable is not allowed, because it can lead to poorly defined behavior if the properties of both GLX drawables don't match. Our driver prevents this, but Compiz appears to try to do this," wrote NVIDIA's Arthur Huillet. The Compiz patch has been accepted upstream.

motang writes: After two years of hard work (and much to the dismay of naysayers who worried the project has been abandoned), the Xfce team has announced the release of Xfce 4.12. Highlights include improvements to the window switcher dialog, intelligent hiding of the panel, new wallpaper settings, better multi-monitor support, improved power settings, additions to the file manager, and a revamped task manager. Here is a quick tour, the full changelog, and the download page. I have been running it since Xubuntu 15.04 beta 1 was released two days ago. It is much improved over 4.10, and the new additions are great.

The State of Linux Gaming In the SteamOS Era 199

Posted by Soulskill
from the penguins-learning-to-rocket-jump dept.
An anonymous reader writes: It's been over a year since Valve announced its Linux-based SteamOS, the biggest push yet from a huge company to bring mainstream gaming to Linux. In this article, Ars Technica takes a look at how their efforts are panning out. Game developers say making Linux ports has gotten dramatically easier: "There are great games shipping for Linux from development teams with no Linux expertise. They hit the 'export to Linux' button in the Unity editor and shipped it and it worked out alright. We didn't get flying cars, but the future is turning out OK so far."

Hardware drivers are still a problem, getting in the way of potential performance gains due to Linux's overall smaller resource footprint than Windows. And while the platform is growing, it's doing so slowly. Major publishers are still hesitant to devote time to Linux, and Valve is taking their time building for it. Their Steam Machine hardware is still in development, and some of their key features are being adopted by other gaming giants, like Microsoft. Still, Valve is sticking with it, and that's huge. It gives developers faith that they can work on supporting Linux without fear that the industry will re-fragment before their game is done.

from the year-of-the-hurr-durr dept.
An anonymous reader writes Following polling on Linus Torvald's Google+ page, he's decided to make the next kernel version Linux 4.0 rather than Linux 3.20. Linux 4.0 is going to bring many big improvements besides the version bump with there being live kernel patching, pNFS block server support, VirtIO 1.0, IBM z13 mainframe support, new ARM SoC support, and many new hardware drivers and general improvements. Linux 4.0 is codenamed "Hurr durr I'ma sheep."

Ask Slashdot: Parental Content Control For Free OSs? 260

Posted by timothy
from the good-idea-or-not dept.
m.alessandrini writes Children grow up, and inevitably they will start using internet and social networks, both for educational and recreational purposes. And it won't take long to them to learn to be autonomous, especially with all the smartphones and tablets around and your limited time. Unlike the years of my youth, when internet started to enter our lives gradually, now I'm afraid of the amount of inappropriate contents a child can be exposed to unprepared: porn, scammers, cyberbullies or worse, are just a click away.

For Windows many solutions claim to exist, usually in form of massive antivirus suites. What about GNU/Linux? Or Android? Several solutions rely on setting up a proxy with a whitelist of sites, or similar, but I'm afraid this approach can make internet unusable, or otherwise be easy to bypass. Have you any experiences or suggestions? Do you think software solutions are only a part of the solution, provided children can learn hacking tricks better than us, and if so, what other 'human' techniques are most effective?

Linux Foundation: Bugs Can Be Made Shallow With Proper Funding 95

Posted by timothy
from the cybernetic-eyeballs-are-people-too dept.
jones_supa writes The record amount of security challenges in 2014 undermined the confidence many had in high quality of open source software. Jim Zemlin, executive director of the Linux Foundation, addressed the issue head-on during last week's Linux Collaboration Summit. Zemlin quoted the oft-repeated Linus' law, which states that given enough eyes, all bugs are shallow. "In these cases the eyeballs weren't really looking", Zemlin said. "Modern software security is hard because modern software is very complex," he continued. Such complexity requires dedicated engineers, and thus the solution is to fund projects that need help. To date, the foundation's Core Infrastructure Initiative has helped out the NTP, OpenSSL and GnuPG projects, with more likely to come. The second key initiative is the Core Infrastructure Census, which aims to find the next Heartbleed before it occurs. The census is looking to find underfunded projects and those that may not have enough eyeballs looking at the code today."

jones_supa (887896) writes "Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data. Ubuntu is now the leading cloud and scale-out Linux-based operating system."

Torvalds: "People Who Start Writing Kernel Code Get Hired Really Quickly" 130

Posted by samzenpus
from the getting-paid dept.
alphadogg writes Now more than ever, the development of the Linux kernel is a matter for the professionals, as unpaid volunteer contributions to the project reached their lowest recorded levels in the latest "Who Writes Linux" report, which was released today. According to the report, which is compiled by the Linux Foundation, just 11.8% of kernel development last year was done by unpaid volunteers – a 19% downturn from the 2012 figure of 14.6%. The foundation says that the downward trend in volunteer contributions has been present for years. According to Linus Torvalds, the shift towards paid developers hasn’t changed much about kernel development on its own. “I think one reason it hasn't changed things all that much is that it's not so much unpaid volunteers are going away as people who start writing kernel code get hired really quickly,” he said.

PC-BSD: Set For Serious Growth? 393

Posted by Soulskill
from the never-say-never dept.
Artem Tashkinov writes: Luke Wolf, a KDE developer, argues that PC-BSD might become a serious desktop OS contender by year 2020, since Linux so far has failed to grasp any serious market share. He writes, "Consider this: In the past 10 years has the distribution you run changed significantly in what it offers over other distributions? I think you'll find the answer is largely no. I do have to give a shout out to openSUSE for the OBS, but otherwise I've used my desktop in the same exact way that I have always used it within the continuity of distribution X,Y, or Z since I started using them. Distributions simply aren't focused on desktop features, they're leaving it up to the DEs to do so." He continues, "PC-BSD on the other hand in fitting with the BSD mindset of holistic solutions is focused on developing desktop features and is moving rapidly to implement them." What do you think?

Removing Libsystemd0 From a Live-running Debian System 755

Posted by samzenpus
from the taking-sides dept.
lkcl writes The introduction of systemd has unilaterally created a polarization of the GNU/Linux community that is remarkably similar to the monopolistic power position wielded by Microsoft in the late 1990s. Choices were stark: use Windows (with SMB/CIFS Services), or use UNIX (with NFS and NIS). Only the introduction of fully-compatible reverse-engineered NT Domains services corrected the situation. Instructions on how to remove systemd include dire warnings that "all dependent packages will be removed", rendering a normal Debian Desktop system flat-out impossible to achieve. It was therefore necessary to demonstrate that it is actually possible to run a Debian Desktop GUI system (albeit an unusual one: fvwm) with libsystemd0 removed. The reason for doing so: it doesn't matter how good systemd is believed to be or in fact actually is: the reason for removing it is, apart from the alarm at how extensive systemd is becoming (including interfering with firewall rules), it's the way that it's been introduced in a blatantly cavalier fashion as a polarized all-or-nothing option, forcing people to consider abandoning the GNU/Linux of their choice and to seriously consider using FreeBSD or any other distro that properly respects the Software Freedom principle of the right to choose what software to run. We aren't all "good at coding", or paid to work on Software Libre: that means that those people who are need to be much more responsible, and to start — finally — to listen to what people are saying. Developing a thick skin is a good way to abdicate responsibility and, as a result, place people into untenable positions.

Wayland 1.7.0 Marks an Important Release 189

jones_supa writes: The 1.7.0 release of Wayland is now available for download. The project thanks all who have contributed, and especially the desktop environments and client applications that now converse using Wayland. In an official announcement from Bryce Harrington of Samsung, he says the Wayland protocol may be considered 'done' but that doesn't mean there's not work to be done. A bigger importance is now given to testing, documentation, and bugfixing. As Wayland is maturing, we are also getting closer to the point where the big Linux distros will eventually start integrating it to their operating system.

jones_supa writes: Linus Torvalds made this post about Linux version numbering: "So, I made noises some time ago about how I don't want another 2.6.39 where the numbers are big enough that you can't really distinguish them. We're slowly getting up there again, with 3.20 being imminent, and I'm once more close to running out of fingers and toes. I was making noises about just moving to 4.0 some time ago. But let's see what people think. So — continue with v3.20, because bigger numbers are sexy, or just move to v4.0 and reset the numbers to something smaller?"

Live Patching Now Available For Linux 117

Posted by timothy
from the not-big-and-fancy dept.
New submitter cyranix writes "You may never have to reboot your Linux machine ever again, even for kernel patching," and excerpts from the long (and nicely human-readable) description of newly merged kernel code that does what Ksplice has for quite a while (namely, offer live updating for Linux systems, no downtime required), but without Oracle's control. It provides a basic infrastructure for function "live patching" (i.e. code redirection), including API for kernel modules containing the actual patches, and API/ABI for userspace to be able to operate on the patches (look up what patches are applied, enable/disable them, etc). It's relatively simple and minimalistic, as it's making use of existing kernel infrastructure (namely ftrace) as much as possible. It's also self-contained, in a sense that it doesn't hook itself in any other kernel subsystem (it doesn't even touch any other code). It's now implemented for x86 only as a reference architecture, but support for powerpc, s390 and arm is already in the works (adding arch-specific support basically boils down to teaching ftrace about regs-saving).

Elementary OS: Why We Make You Type "$0" 208

Posted by samzenpus
from the drop-a-dollar-in-the-bucket dept.
jones_supa writes Open source software can always be acquired without charge, but can still incur significant development costs. Elementary OS wants to make people aware of this, and have changed their website to suggest donating when downloading, and make users explicitly enter "$0" if they want a free download. This is the same strategy Canonical has used when offering Ubuntu. The Elementary OS blog explains: "Developing software has a huge cost. Some companies offset that cost by charging hundreds of dollars for their software, making manufacturers pay them to license the software, or selling expensive hardware with the OS included. Others offset it by mining user data and charging companies to target ads to their users. [...] If we want to see the world of open source software grow, we should encourage users to pay for its development; otherwise it'll be underfunded or developers will have to resort to backdoor deals and advertising. And nobody wants that future." Currently the only people who have received money for working on Elementary OS have been community members through their bounty program.
