Linux 3.17 To Fix Up ASPM, Bring Other PCI Changes

Filed under
Linux

Bjorn Helgaas, the PCI subsystem maintainer for the Linux kernel, sent in a very early Linux 3.17 kernel merge window pull request due to being on holiday the next few weeks.

The PCI pull request is the first pull request submitted for Linux 3.17 with it likely being about two weeks or so until Linux 3.16 makes its official debut, which would conflict with Bjorn's holiday until mid-August.

Nine Reasons Linux Rules the Supercomputing Space

Filed under
Linux

The latest TOP500 List of the fastest supercomputers in the world helped many in the technology community understand what open-source aficionados have known for years: Linux has quickly become the operating system of choice in the high-performance computing (HPC) market, growing from relative obscurity 15 years ago to powering 97 percent of the fastest computers in the world. But its appeal is found in more than cost or choice. Here are a few of the main reasons Linux has grown to own the lion's share of the fastest supercomputers in the world. Although the United States remains the top country in terms of overall systems, with 233, this is down from 265 on the November 2013 list. The number of Chinese systems on the list rose from 63 to 76, giving the Asian nation nearly as many supercomputers as the United Kingdom, with 30; France, with 27; and Germany, with 23—combined. Japan also increased its showing, up to 30 from 28 on the previous list. HP has the lead in systems and now has 182 systems (36 percent), compared to IBM, with 176 systems (35 percent). HP had 196 systems (39 percent) six months ago, and IBM had 164 systems (33 percent) six months ago. In the system category, Cray remains third with 10 percent (50 systems).

The Linux Kernel Bang-Bang Thermal Governor Is Banging

Development
Linux

The Bang-bang thermal governor remains under discussion on the kernel mailing list after patches for it originally appeared a few months back. Bang-bang will hopefully be ready for an upcoming kernel release (Linux 3.17?) and the latest technical discussion about it can be found via the LKML archives.

One Linux kernel driver already planning to utilize the Bang-bang thermal governor is the "Acerhdf" driver that serves as the fan driver for Acer's Aspire One and other Acer systems where it has a simple fan that only supports being on or off. Up to now the acerhdf driver has handled its own on-off controls by post-manipulating the kernel's thermal subsystem trip point handling but will now be able to utilize the unified Bang-bang governor.

Best Linux Desktop: KDE's Plasma

Filed under
KDE
Linux

From ratpoison to Unity, I must have tried just about every Linux desktop environment available. The best Linux desktop, in my view: my main computer continues to run KDE's Plasma. No other alternative can match its design philosophy, configurability, or its innovations on the classical desktop.

Nor am I alone in my preferences. At a time when the Linux desktop offers six main alternatives (Cinnamon, GNOME, KDE Plasma, LXDE, Mate, Unity and Xfce), KDE Plasma consistently tops reader polls with an average of 35-40 percent. In such a diverse market, these figures indicate a broad appeal that other Linux desktop alternatives can't match.

I believe that one of the main reasons for this appeal is the KDE design philosophy. GNOME and Unity may offer a more aesthetic-looking default, but only at the cost of simplifying both the desktop and the utilities in the name of reducing clutter.

Meet the DragonBox Pyra, the Linux DS equivalent

I’m a begrudging Linux user, specifically Ubuntu. It’s the result of being too cheap to buy software like Photoshop and too ethical to just steal it like everybody else. As a result I get to enjoy all the benefits of free software, including the attempts to develop the “perfect” portable console, like the DragonBox Pyra.

4MLinux Rescue Edition 9.1 Beta Is a Good Tool for Beginners and Professionals Alike

Filed under
Linux

All the 4MLinux operating systems have really small sizes, but the Rescue Edition is actually bigger than most of the other flavors. There is a very good reason for that size and it all has to do with the integrated packages. The OS could have been a little bit smaller, but the developer would have been forced to remove some important applications.

Russia’s parliament is preparing new rules in a bid to cut its reliance on foreign technology suppliers after U.S. sanctions against some of the country’s largest companies, a move that could hurt sales at vendors such as Microsoft Corp. (MSFT) and International Business Machines Corp. (IBM)

The State Duma, Russia’s lower house of parliament, is drafting a bill to require government agencies and state-run enterprises to give preference to local providers of software and hardware, according to a document from the commission for strategic information systems obtained by Bloomberg News. The paper addresses criteria for tender processes such as favoring products that don’t have imported, licensed components.

Security: Equifax, Kodi, Infrared, and Windows XP in 2017

  • Safer but not immune: Cloud lessons from the Equifax breach
  • Warning: If you are using this Kodi repository, you could be in danger
    Kodi is quite possibly the best media center software of all time. If you are looking to watch videos or listen to music, the open source solution provides an excellent overall experience. Thanks to its support for "addons," it has the potential to become better all the time. You see, developers can easily add new functionality by writing an addon for the platform. And yes, some addons can be used for piracy, but not all of them are. These addons, such as Exodus and Covenant, are normally added using a repository, which hosts them. [...] We do not know 100 percent if the person that re-registered the metalkettle name on GitHub is planning anything evil, but it is better to be safe than sorry.
  • Infrared signals in surveillance cameras let malware jump network air gaps
    The malware prototype could be a crucial ingredient for attacks that target some of the world's most sensitive networks. Militaries, energy producers, and other critical infrastructure providers frequently disconnect such networks from the Internet as a precaution. In the event malware is installed, there is no way for it to make contact with attacker-controlled servers that receive stolen data or issue new commands. Such airgaps are one of the most basic measures for securing highly sensitive information and networks. The proof-of-concept malware uses connected surveillance cameras to bridge such airgaps. Instead of trying to use the Internet to reach attacker-controlled servers, the malware weaves passwords, cryptographic keys, and other types of data into infrared signals and uses a camera's built-in infrared lights to transmit them. A nearby attacker then records the signals with a video camera and later decodes embedded secrets. The same nearby attackers can embed data into infrared signals and beam them to an infected camera, where they're intercepted and decoded by the network malware. The covert channel works best when attackers have a direct line of sight to the video camera, but non-line-of-sight communication is also possible in some cases.
  • Manchester police still relies on Windows XP
    England's second biggest police force has revealed that more than one in five of its computers were still running Windows XP as of July. Greater Manchester Police told the BBC that 1,518 of its PCs ran the ageing operating system, representing 20.3% of all the office computers it used. Microsoft ended nearly all support for the operating system in 2014. Experts say its use could pose a hacking risk. The figure was disclosed as part of a wider Freedom of Information request. "Even if security vulnerabilities are identified in XP, Microsoft won't distribute patches in the same way it does for later releases of Windows," said Dr Steven Murdoch, a cyber-security expert at University College London.

Flock 2017, Fedora 27, and New Fedora 26 (F26) ISO

  • Flock 2017: How to make your application into a Flatpak?
  • Flock to Fedora 2017
  • Flock 2017 – A Marketing talk about a new era to come.
    I had two session at Flock this year, one done by me and another in support of Robert Mayr in the Mindshare one, if there were been any need for discussing. Here I’m talking about my session: Marketing – tasks and visions (I will push the report about the second one after Robert’s one, for completion). In order to fit the real target of a Flock conference (that is a contributor conference, not a show where people must demonstrate how much cool they are; we know it!) is to bring and show something new, whether ideas, software, changes and so on, and discuss with other contributors if they’re really innovative, useful and achievable.
  • F26-20170918 Updated Live isos released
  • GSoC2017 Final — Migrate Plinth to Fedora Server
  • Building Modules for Fedora 27
    Let me start with a wrong presumption that you have everything set up – you are a packager who knows what they want to achieve, you have a dist-git repository created, you have all the tooling installed. And of course, you know what Modularity is, and how and why do we use modulemd to define modular content. You know what Host, Platform, and Bootstrap modules are and how to use them.

Will Microsoft love Linux to death? Shuttleworth and Stallman on whether Windows 10 is free software's friend

Richard Stallman is a free-software activist and creator of the GNU OS that forms part of the basis of modern GNU/Linux distros. He believes that Microsoft's decision to build a Windows Subsystem for Linux (WSL) amounts to an attempt to extinguish software that users are free to run, copy, distribute, study, change and improve. "It certainly looks that way. But it won't be so easy to extinguish us, because our reasons for using and advancing free software are not limited to practical convenience," he said. "We want freedom. As a way to use computers in freedom, Windows is a non-starter." Read more
