The world's most secure OS may have a serious problem

The Tails operating system is one of the most trusted platforms in cryptography, favored by Edward Snowden and booted up more than 11,000 times per day in May. But according to the security firm Exodus Intelligence, the program may not be as secure as many thought. The company says they've discovered an undisclosed vulnerability that will let attackers deanonymize Tails computers and even execute code remotely, potentially exposing users to malware attacks. Exodus is currently working with Tails to patch the bug, and expects to hand over a full report on the exploit next week.

It’s now easier to install SailfishOS on Android devices

Linux

Sailfish OS is a new venture by ex-nokia employees which aims to bring a new independent partner friendly mobile operating system to wireless devices. However, as the mobile ecosystem today is quite fragmented, a new OS brings in a lot of work for developers to port the new OS in their existing devices. The Sailfish OS team knew this problem and have come out with a Hardware Adaptation Dev kit which will help developers to port and run Sailfish OS on any device capable of running Cyanogen Mod 10.1.x.

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

Filed under
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.

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

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 to Reduce Reliance on Microsoft, IBM After Sanctions

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.

Earlier this month AMD published an open-source HSA Linux driver for exploiting the potential of their much-promoted Heterogeneous System Architecture. This driver, now known as the "AMDKFD" driver, is up to its second revision and continues being analyzed by developers on the mailing list.

The aforelinked article goes over all the basic AMD HSA Linux driver details while its the AMD-specific HSA driver that's being worked on the most and discussed. Version two of the "AMDKFD" driver came out on Thursday and lives under the DRM Radeon GPU driver as the "AMDKFD" to provide the "HSA kernel driver for AMD Radeon devices."

Can Linux speed in-car systems? Software may reduce development time, costs

Filed under

OSS

The open-source software revolution is coming to the car. Most in-vehicle infotainment systems sold today use proprietary software, with the underlying code tightly controlled by automakers and by a few major software providers, such as Microsoft Corp. and Ottawa-based QNX Software Systems. Now the auto industry is exploring open-source operating systems such as Linux more seriously than ever, hoping that sharing the work and making code available to all will lead to more rapid development cycles, lower costs and happier drivers.
