Linux 3.15 Speeds Up Suspend/Resume Performance

Filed under
Linux

The suspend and resume code impacts users who run Linux on laptop computers where there is a need to suspend disk and operating system operations when a device is closed and then start up again when the device is opened. Williams noted that his code contribution was inspired by an analysis and proposal from Intel developer Todd Brandt. Brandt's proposal specifically dealt with a suspend/resume speed improvement, enabling a rapid wakeup from a device's suspend state

How does the cloud affect the everyday linux user?

Filed under
Linux

Cloud computing has really become the buzz term for any online service. Your web browser is a client connecting to a server or clusters of servers hosted anywhere in the world. The point is that you don't care. You don't need to know.

Generally speaking I have barely touched the surface. We all use the cloud everyday and most of us don't even think about it.

How does the cloud affect the everyday linux user? It turns out quite a bit.

Is the cloud a good or bad thing? Neither. Each service has to be judged on it's own merits.

The term "The Cloud" is just something marketing people and the technical press get excited about. Anyone remember when they kept using the term "Web 2.0"?

Trevilla Theme Is One of the Best Flat Themes for Ubuntu and Linux Mint

Ubuntu

The Trevilla theme pack is made for people who like to have a flat desktop and it comes with clean headers and buttons that are very good for a minimalistic experience.

The Trevilla designers are not the only ones using this flat look for themes. In fact, more and more distros come with flat desktops and it looks like these types of decorations are not going anywhere...

At Bodhi we work firmly on a "its ready when its ready schedule" as opposed to sticking to our set release goals and churning out something we are not happy with. Better late than never as the saying goes! Just ten days after the targeted release date I am happy to share our first Release Candidate for Bodhi Linux's third major release...

Review: Pinguy OS 14.04 LTS "Papercut"

Filed under
GNU
Linux

This was originally supposed to be a comparison test against Antergos, which is another distribution that ships GNOME 3/Shell and aims for new users to Linux. Unfortunately, Antergos refused to boot. Therefore, what is left is a typical review of Pinguy OS, albeit with some more critical remarks than usual about how well it really caters to newbies (left over from when this article was a comparison test). Follow the jump to see what it is like...

NVIDIA 340.17 Beta Driver for Linux Brings G-SYNC Monitor Support

Filed under
Linux

According to the changelog, various improvements and corrections have been made to the information reported to GL applications via the KHR_debug and ARB_debug_output extensions, a bug that caused the GLX applications that simultaneously created drawables on multiple X servers to crash when swapping buffers has been fixed, and the nvidia-settings option has been updated to report all valid names for each target when querying target types, e.g. “nvidia-settings -q gpus.”

Also, support has been added for controlling the availability of Fast Approximate Antialiasing (FXAA) on a per-application basis via the new __GL_ALLOW_FXAA_USAGE environment variable, a bug that occurred when indirect rendering could become corrupted on system configurations that disallow writing to executable memory has been fixed, and the runlevel check has been removed from the nvidia-installer.

BlueBorne Vulnerability Is Patched in All Supported Ubuntu Releases, Update Now

Canonical released today new kernel updates for all of its supported Ubuntu Linux releases, patching recently discovered security vulnerabilities, including the infamous BlueBorne that exposes billions of Bluetooth devices. The BlueBorne vulnerability (CVE-2017-1000251) appears to affect all supported Ubuntu versions, including Ubuntu 17.04 (Zesty Zapus), Ubuntu 16.04 LTS (Xenial Xerus) up to 16.04.3, Ubuntu 14.04 LTS (Trusty Tahr) up to 14.04.5, and Ubuntu 12.04 LTS (Precise Pangolin) up to 12.04.5.

Security: Updates, 2017 Linux Security Summit, Software Updates for Embedded Linux and More

  • Security updates for Tuesday
  • The 2017 Linux Security Summit
    The past Thursday and Friday was the 2017 Linux Security Summit, and once again I think it was a great success. A round of thanks to James Morris for leading the effort, the program committee for selecting a solid set of talks (we saw a big increase in submissions this year), the presenters, the attendees, the Linux Foundation, and our sponsor - thank you all! Unfortunately we don't have recordings of the talks, but I've included my notes on each of the presentations below. I've also included links to the slides, but not all of the slides were available at the time of writing; check the LSS 2017 slide archive for updates.
  • Key Considerations for Software Updates for Embedded Linux and IoT
    The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers. Many of these embedded devices run a variant of embedded Linux; typically, the distribution size is around 16MB today. Unfortunately, the Linux kernel, although very widely used, is far from immune to critical security vulnerabilities as well. In fact, in a presentation at Linux Security Summit 2016, Kees Cook highlighted two examples of critical security vulnerabilities in the Linux kernel: one being present in kernel versions from 2.6.1 all the way to 3.15, the other from 3.4 to 3.14. He also showed that a myriad of high severity vulnerabilities are continuously being found and addressed—more than 30 in his data set.
