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)."
New submitter mathiasfriman writes: SverigeLinux (SwedenLinux in Swedish) is a project financed by the Swedish Internet Fund that is developing a Linux deployment system for the public sector. It is based on DebianLAN and has just released its first public early alpha version. This 7 minute video shows how you can deploy up to 100 workstations with minimal Linux knowledge in under an hour, complete with DHCP, DNS and user data in LDAP, logins using Kerberos and centralized storage. The project has a home on GitHub and is looking for testers and developers. Don't worry, no Björgen Kjörgen; it's all in English.
New submitter KeithCu writes with a lengthy explanation of the joys (and just a handful of glitches) he's had in running Arch Linux on his ultraportable, a Lenovo Yoga 2. Other than the hardware-specific issues, I've been amazed by how well Arch Linux works, given that it doesn't have release cycles, or a big team with a lot of money supporting and marketing it. I've heard only 30 developers maintain the core Arch packages, with most of them having a full-time job doing something else! At the same time, it shouldn't be a total surprise things work so well, because free software doesn't just fall off a turnip truck. Not many reviews feature pictures of a laptop charred from building LibreOffice.
An anonymous reader writes: GCC 5 is coming up for release in the next few weeks and is presenting an extraordinary number of new features: C11 support by default, experimental C++14 support, full C++11 support in libstdc++, OpenMP 4.0 with Xeon Phi / GPU offloading, Intel Cilk Plus multi-threading, new ARM processor support, Intel AVX-512 handling, and much more. This is a big release, so those wishing to test it ahead of time can obtain the preliminary GCC 5 source code from GCC's snapshots mirror.
LibbyMC writes Git will celebrate its 10-year anniversary tomorrow. To celebrate this milestone, Linus shares the behind-the-scenes story of Git and tells us what he thinks of the project and its impact on software development. From the article: "Ten years ago this week, the Linux kernel community faced a daunting challenge: They could no longer use their revision control system BitKeeper and no other Software Configuration Management (SCMs) met their needs for a distributed system. Linus Torvalds, the creator of Linux, took the challenge into his own hands and disappeared over the weekend to emerge the following week with Git. Today Git is used for thousands of projects and has ushered in a new level of social coding among programmers."
jones_supa writes Phoronix has noticed that the Visual Studio 2015 product page mentions that the new IDE can target Linux out of the box. Specifically the page says "Build for iOS, Android, Windows devices, Windows Server or Linux". What this actually means is not completely certain at this point, but it certainly laces nicely with the company opening up the .NET Framework. And speaking of cross-platform software: new submitter mccrew writes Google has released a tool that lets Android apps run on any machine that can run its Chrome browser. Called Arc Welder, the tool acts as a wrapper around Android apps so they can run on Windows, OS X and Linux machines. The software expands the places that Android apps can run and might make it easier for developers to get code working on different machines.
jones_supa writes A critical vulnerability has been found in the MPEG-1 Layer III playback backend of Mozilla Firefox and Thunderbird. Security researcher Aki Helin reported a use-after-free scenario when playing certain audio files on the web using the Fluendo MP3 plugin for GStreamer on Linux. This is due to a flaw in handling certain MP3 files by the plugin and its interaction with Mozilla code. A maliciously crafted MP3 file can lead to a potentially exploitable crash. Linux is the only affected platform, so Windows and OS X users are safe from this particular vulnerability.
kthreadd writes Version 3.16 of GNOME, the primary desktop environment for GNU/Linux operating systems has been released. Some major new features in this release include a overhauled notification system, an updated design of the calendar drop down and support for overlay scrollbars. Also, the grid view in Files has been improved with bigger thumbnail icons, making the appearance more attractive and the rows easier to read. A video is available which demonstrates the new version.
An anonymous reader writes: Linux Voice magazine has published a long article about how people go about reverse engineering drivers for hardware peripherals. They use Python and a USB radio-controlled car to demonstrate, walking us through the entire process. It's a cool, easy-to-follow insight into what often seems to be a rather opaque process.
jones_supa writes: Hardware that sports the "Designed for Windows 8" logo requires machines to support UEFI Secure Boot. When the feature is enabled, the core software components used to boot the machine are verified for correct cryptographic signatures, or the system refuses to boot. This is a desirable security feature, because it protects from malware sneaking into the boot process. However, it has an issue for alternative operating systems, because it's likely they won't have a signature that Secure Boot will authorize. No worries, because Microsoft also mandated that every system must have a UEFI configuration setting to turn the protection off, allowing booting other operating systems. This situation may now change. At its WinHEC hardware conference in Shenzhen, China, Microsoft said the setting to allow Secure Boot to be turned off will become optional when Windows 10 arrives. Hardware can be "Designed for Windows 10," and offer no way to opt out of the Secure Boot lock down. The choice to provide the setting (or not) will be up to the original equipment manufacturer.
An anonymous reader writes My daughter is in her third year of college as a physics major. She has an internship in Europe this summer, will graduate next year, and continue with graduate physics studies. Her area of research interest is in gravitational waves and particle physics. She currently has a laptop running Win7 and wants to buy a new laptop. She would like to use Linux on it, and plans to use it for C++ programming, data analysis and simulations (along with the usual email, surfing, music, pictures, etc). For all of the physics-savvy Slashdotters out there: what should she get? PC? Mac? What do you recommend for running Linux? For a C++ development environment? What laptop do you use and how is it configured to support your physics-related activities?
An anonymous reader points to a story in the Salt Lake Tribune which says that The nearly defunct Utah company SCO Group Inc. and IBM filed a joint report to the U.S. District Court in Salt Lake City saying that legal issues remain in the case, which was initiated in 2003 with SCO claiming damages of $5 billion against the technology giant, based in Armonk, N.Y. That likely means that U.S. District Judge David Nuffer, who now presides over the dispute, will start moving the lawsuit — largely dormant for about four years while a related suit against Novell Inc. was adjudicated — ahead. What kind of issues? In addition to its claims of IBM misappropriation of code, SCO alleges that IBM executives and lawyers directed the company's Linux programmers to destroy source code on their computers after SCO made its allegations. The company's other remaining claims are that IBM's actions amounted to unfair competition and interference with its contracts and business relations with other companies. IBM has remaining claims against SCO that allege the Utah company violated contracts, copied and distributed IBM code that had been placed in Linux and that SCO created a campaign of "fear, uncertainty and doubt" about IBM's products and services because of the dispute over Unix code.
jones_supa writes Some of us remember the story of why Linux kernel responds "False" when ACPI BIOS asks if the operating system is Linux. We have found yet another case where mimicking the Windows behavior instead of writing to the spec is the right choice if you just want your machine to work properly. The ACPI spec defines the _REV object as evaluating to the revision of the ACPI specification that the OS implements. Linux returns 5 for this, because Linux actually tries to implement ACPI 5.0, but Windows returns 2 (ACPI 2.0), possibly due to legacy reasons. Linux kernel expert Matthew Garrett discovered that still a fair amount of brokenness appears when 5 is returned as the revision, including a Dell machine which left the sound hardware in a misconfigured state. He is proposing a kernel patch which simply reports _REV as 2 on all x86 hardware.
jrepin writes KDE is among the biggest open source projects which continues to innovate and evolve with the changing times. Often we have seen this particular community create technologies ahead of its time which were later adopted by other projects. The Linux Foundation talked to Lydia Pintscher, the president of the KDE e.V., the nonprofit organization that oversees the legal and financial aspects of the KDE project, to understand the relationship between the community and the organization. We also discussed the challenge of recruiting more women to open source projects and women in the KDE community.
