itwbennett writes: A team of developers has created a rootkit for Linux systems that uses the processing power and memory of graphics cards instead of CPUs in order to remain hidden. The rootkit, called Jellyfish, is a proof of concept designed to demonstrate that completely running malware on GPUs is a viable option. Such threats could be more sinister than traditional malware programs, according to the Jellyfish developers, in part because there are no tools to analyze GPU malware, they said.

An anonymous reader writes: A team of engineers and artists has launched a Kickstarter campaign for C.H.I.P., a small computer that costs $9. The campaign met and far exceeded its $50,000 goal on the first day. The device runs an R8 ARM CPU clocked at 1 GHz, 512 MB of RAM, and 4GB of storage. It has built-in Wi-Fi and Bluetooth, and runs a version of Debian. The price was enabled by two things: super-cheap Chinese tablets pushing down processor costs, and support from manufacturer Allwinner to make it even cheaper. The team is also building breakout boards for VGA and HDMI connections, as well as one with a tiny LCD screen, keyboard, and battery. Importantly, "all hardware design files schematic, PCB layout and bill of materials are free for you the community to download, modify and use."

jones_supa writes: Microsoft is announcing that PowerShell Desired State Configuration (DSC) for Linux is available for download in form of RPM and DEB packages. DSC is a new management platform that provides a set of PowerShell extensions that you can use to declaratively specify how you want your software environment to be configured. You can now use the DSC platform to manage the configuration of both Windows and Linux workloads with the PowerShell interface. Microsoft says that bringing DSC to Linux is another step in the company's "broader commitment to common management of heterogeneous assets in your datacenter or the public cloud." Adds reader benjymouse: DSC is in the same space as Chef and Puppet (and others); but unlike those, Microsofts attempts to build a platform/infrastructure based on industry standards like OMI to allow DSC to configure and control both Windows, Linux and other OSes as well as network equipment like switches, etc.

jones_supa writes: "One of the most puzzling questions about the history of free and open source software is this: Why did Linux succeed so spectacularly, whereas similar attempts to build a free or open source, Unix-like operating system kernel met with considerably less success?" Christopher Tozzi has rounded up some theories, focusing specifically on kernels, not complete operating systems. These theories take a detailed look at the decentralized development structure, pragmatic approach to things, and the rich developer community, all of which worked in favor of Linux.

An anonymous reader sends this report from opensource.com: GNU/Linux distributions provide great advantages over proprietary alternatives for people with disabilities. All the accessibility tools included in Linux are open source, meaning their code is readily available if you want to examine or improve it, and cost nothing. Hardware devices, of course, are still going to cost money. Additionally, accessibility software on other platforms generally contain licensing constraints on the user. ... When it comes to accessibility, Linux is not without issues. ... The number of developers who specifically work on accessibility tools is quite small. For example, there is only one Orca developer, two AT-SPI developers, and a single GTK developer. ... Developers who do not depend on assistive technologies tend to forget—or don't know—that a disabled person might want to use their application, read their web page, and so on. ... The problem is not necessarily that developers do not care. Rather, it's is that accessibility is highly specialized and requires someone with knowledge in the area, regardless of platform.

jones_supa writes: Canonical released Ubuntu 15.04 a couple of weeks ago, and it seems that this release has been a success. The community is mostly reporting a nice experience, which is important since this is the first Ubuntu release that uses systemd instead of upstart. At Slashdot, people have been very nervous about systemd, and last year it was even asked to say something nice about it. To be fair, Ubuntu 15.04 hasn't changed all that much. Some minor visual changes have been implemented, along with a couple of new features, but the operating system has remained pretty much the same. Most importantly it is stable, fast, and it lacks the usual problems accompanied by new releases.

What's more, it seems that the spammers are connected with a software company called Yellsoft, which sells DirectMailer, a "system for automated e-mail distribution" that allows users to send out anonymous email in bulk. Here's the white paper in which the researchers explain the exploit.

ClockEndGooner writes: Microsoft is still extending its efforts into cross platform development with the release of a preview edition of Visual Studio Code, "a lightweight cross-platform code editor for writing modern web and cloud applications that will run on OS X, Linux and Windows." Derived from its Monaco editor for Visual Studio Online, the initial release includes rich code assistance and navigation for JavaScript, TypeScript, Node.js, ASP.NET 5, C# and many others.

An anonymous reader sends this announcement from the debian-hurd mailing list: It is with huge pleasure that the Debian GNU/Hurd team announces the release of Debian GNU/Hurd 2015. This is a snapshot of Debian "sid" at the time of the stable Debian "jessie" release (April 2015), so it is mostly based on the same sources. It is not an official Debian release, but it is an official Debian GNU/Hurd port release. The installation ISO images can be downloaded from Debian Ports in the usual three Debian flavors: NETINST, CD, or DVD. Besides the friendly Debian installer, a pre-installed disk image is also available there, making it even easier to try Debian GNU/Hurd. The easiest way to run it is inside a VM such as qemu.

jrepin writes: The KDE community has released Plasma 5.3, a major new version of the popular, open source desktop environment. The latest release brings much enhanced power management, better support for Bluetooth, and improved Plasma widgets. Also available is a technical preview of Plasma Media Center shell. In addition, Plasma 5.3 represents a big step towards support for the Wayland windowing system. There are also a few other minor tweaks and over 300 bugfixes. Here is the full changelog, and here's the package download wiki page.

DeviceGuru writes: Imagination Technologies has developed a Linux-ready academic version of its 32-bit MIPS architecture MicroAptiv processor design, and is giving it away free to universities for use in computer research and education. As the MIPSfpga name suggests, the production-quality RTL (register transfer level) design abstraction is intended to run on industry standard FPGAs. Although MIPSfpga is available as a fully visible RTL design, MIPSfpga is not fully open source, according to the announcement from Robert Owen, Manager of Imagination's University Programme. Academic users can use and modify MIPSfpga as they wish, but cannot build it into silicon. "If you modify it, you must talk to us first if you wish to patent the changes," writes Owen.

An anonymous reader writes: The first release candidate of Linux 4.1 is now available. Linus noted, "The merge window is pretty normal in terms of what got merged too. Just eyeballing the size, it looks like this is going to fit right in — while 4.0 was a bit smaller than usual, 4.1 seems to be smack dab in the middle of the normal range for the last couple of years." There are numerous new features in Linux 4.1, like Xbox One controller force feedback support, better Wacom tablet support, Intel Atom SoC performance improvements, Radeon DisplayPort MST support, EXT4 file-system encryption, ChromeOS Lightbar support, and ACPI for 64-bit ARM, among other additions. However, KDBUS wasn't accepted for Linux 4.1.

linuxscreenshot writes: After almost 24 months of constant development, the Debian project is proud to present its new stable version 8 (code name Jessie), which will be supported for the next five years thanks to the combined work of the Debian Security team and the Debian Long Term Support team. (Release notes.) Jessie ships with a new default init system, systemd. The systemd suite provides features such as faster boot times, cgroups for services, and the possibility of isolating part of the services. The sysvinit init system is still available in Jessie. Screenshots and a screencast are available.

jones_supa writes: The final release of Ubuntu 15.04 is now available. A modest set of improvements are rolling out with this spring's Ubuntu. While this means the OS can't rival the heavy changelogs of releases past, the adage "don't fix what isn't broken" is clearly one 15.04 plays to. The headline change is systemd being featured first time in a stable Ubuntu release, which replaces the inhouse UpStart init system. The Unity desktop version 7.3 receives a handful of small refinements, most of which aim to either fix bugs or correct earlier missteps (for example, application menus can now be set to be always visible). The Linux version is 3.19.3 further patched by Canonical. As usual, the distro comes with fresh versions of various familiar applications.

An anonymous reader writes: AMD has made available its new AMDGPU Linux graphics driver comprised of a brand new DRM/KMS kernel driver, a new xf86-video-amdgpu X11 driver, and modifications to libdrm and Gallium3D. This new AMDGPU driver is designed for supporting AMD's next-generation hardware with no support differences for currently supported Radeon GPUs. While yet to be released, this new AMDGPU driver is the critical piece to the new unified driver strategy with Catalyst where their high performance proprietary driver will now become limited to being a user-space binary component that uses this open-source kernel driver.

John 'Warthog9' Hawley was the boss sysadmin on kernel.org before he jumped to Intel in April, 2014, as an open hardware technical evangelist. He last showed up on Slashdot in June, 2014, with his Dr. Who-inspired Robot K-9. Now he's talking about flight computers for quadcopters, specifically ones based on MinnowBoards. Last month (April 2015) he was speaking at the Embedded Linux Conference + Android Builders Summit. That's where he and Timothy Lord had this conversation about flight controllers for UAVs, which makes it a fitting sequel to yesterday's video, which was also about controlling drones with real-time Linux.

jones_supa writes: The KDE project today announced the release of KDE Plasma 5.3 beta. It brings better power management, improved Bluetooth support, improved widgets, Wayland support, new media center, and nearly 350 bugfixes. The power management improvements include settings that can be independently configured per activity, there is a new energy usage monitor available in KInfoCenter, and a battery applet identifies applications that hog power. Bluetooth applet brings added support for blocking and unblocking devices. New touchpad module has been added as well. The combined window manager and compositor KWin is now able to start a nested XWayland server, which acts as a bridge between the old X11 and the new Wayland world.

jones_supa writes: A massive x86 assembly code spring cleaning has been done in a pull request that is to end up in Linux 4.1. The developers have tried testing the code on many different x86 boxes, but there's risk of regression when exposing the code to many more systems in the days and weeks ahead. That being said, the list of improvements is excellent. There are over 100 separate cleanups, restructuring changes, speedups and fixes in the x86 system call, IRQ, trap and other entry code, part of a heroic effort to deobfuscate a decade old spaghetti assembly code and its C code dependencies.

An anonymous reader writes "The Linux 4.0 kernel has been released. Linux 4.0 brings many features including live patching, Radeon DisplayPort Audio, RadeonSI fan control improvements, new OverlayFS functionality, Intel Quark SoC support, and a heck of a lot more. Linus's release announcement reads in part: "So I decided to release 4.0 as per the normal schedule, because there really weren't any known issues, and while I'll be traveling during the end of the upcoming week due to a college visit, I'm hoping that won't affect the merge window very much. We'll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously 'small' is all relative. It's still over 10k non-merge commits. But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones)."
