AV Linux Multimedia-Focused OS Gets New Stable Release with Meltdown Patches

Linux
Security

AV Linux, the open-source GNU/Linux distribution designed for multimedia content creation, has been updated recently to version 2018.4.2, a release that adds Meltdown mitigations, updated components, and various other enhancements.

Probably the most important change in the AV Linux 2018.4.2 release is the implementation of the KPTI (Kernel page-table isolation) patch to protect users against the Meltdown security vulnerability, but only for 64-bit installations. The distribution is now powered by the long-term supported Linux 4.9.76 kernel, and users can disable the KPTI patch at boot.

Nearly 15 million Nintendo Switches are now hackable (other NVIDIA Tegra X1 devices too)

Earlier this year hackers started to show evidence of an exploit that allowed you to load custom software on a Nintendo Switch game console. Theoretically that opens the door for homebrew applications, modified games, or even running an alternate operating system such as a GNU/Linux distribution on Nintendo’s latest game system. It could also make it possible to run pirated games, which is why console makers usually don’t encourage this sort of thing.

But now a team of hackers called ReSwitched have described a bootrom vulnerability called Fusée Gelée that makes it possible for anyone to hack a Nintendo Switch… assuming you’re willing to do a little hardware hacking too.

Ubuntu

Lead by talented Linux developer Marius Gripsgard, the UBports Foundation keeps the Ubuntu Touch mobile OS developed by Canonical, the company behind the widely-used Ubuntu Linux operating system, alive for various popular smartphones, including Fairphone 2, Nexus 5, OnePlus One, as well as the BQ Aquaris M10 FHD tablet that was designed to run Ubuntu Touch in the first place.

Now, Purism and UBports are partnering to offer the Ubuntu Touch mobile operating system on the upcoming Librem 5 Linux phone, which raised more than $2 million last fall​, promising to be the privacy and security-focused smartphone you've been expecting for a long time. While not the default OS, users will be able to easily run Ubuntu Touch on the Librem 5 phone.

Record Terminal Activity For Ubuntu 16.04 LTS Server

Linux

At times system administrators and developers need to use many, complex and lengthy commands in order to perform a critical task. Most of the users will copy those commands and output generated by those respective commands in a text file for review or future reference. Of course, “history” feature of the shell will help you in getting the list of commands used in the past but it won’t help in getting the output generated for those commands.

Linux Kernel Maintainer Statistics

Filed under
Linux

As part of preparing my last two talks at LCA on the kernel community, “Burning Down the Castle” and “Maintainers Don’t Scale”, I have looked into how the Kernel’s maintainer structure can be measured. One very interesting approach is looking at the pull request flows, for example done in the LWN article “How 4.4’s patches got to the mainline”. Note that in the linux kernel process, pull requests are only used to submit development from entire subsystems, not individual contributions. What I’m trying to work out here isn’t so much the overall patch flow, but focusing on how maintainers work, and how that’s different in different subsystems.

Kernel and Graphics: BUS1, Linux 4.17 RC2, Wayland's Weston and Mesa

  • BUS1 Still Remains Out Of The Mainline Linux Kernel, But DBus-Broker Continues

    The BUS1 in-kernel IPC mechanism born out of the ashes of KDBUS still hasn't been mainlined in the Linux kernel, but its code is still improved upon from time to time. At least though DBus-Broker as a new performance-oriented D-Bus implementation continues gaining ground in user-space.

    DBus-Broker was announced last year as a new message bus implementation of D-Bus focused on high performance and reliability while continuing to offer compatibility with the original D-Bus implementation.

  • Wayland's Weston Gets Optimizations For Its Pixman Renderer

    Wayland's Weston reference compositor with its Pixman software-based renderer back-end has received a number of performance optimizations.

    Fabien Lahoudere of Collabora posted a set of patches today to optimize the Pixman renderer for Weston. In particular, there are optimizations around compositing damage to the screen as well as optimizing the shadow buffer usage. The Weston Pixman renderer is often used as a software accelerated fallback in cases where no GPU hardware acceleration may be available. As implied by the name, it uses the long-standing Pixman library that is also used by Cairo, the X.Org Server, etc, for pixel manipulation on the CPU.

New Terminal App in Chome OS Hints at Upcoming Support for Linux Applications

Linux

According to a Reddit thread, a Chromebook user recently spotted a new Terminal app added to the app drawer when running on the latest Chrome OS Dev channel. Clicking the icon would apparently prompt the user to install the Terminal app, which requires about 200 MB of disk space.

The installation prompt notes the fact that the Terminal app can be used to develop on your Chromebook. It also suggests that users will be able to run native apps and command-line tools seamlessly and securely. Considering the fact that Chrome OS is powered by the Linux kernel, this can only mean one thing.

  • Ten Years of Vim
     

    The philosophy behind Vim takes a while to sink in: While other editors focus on writing as the central part of working with text, Vim thinks it's editing.

     

    You see, most of the time I don't spend writing new text; instead, I edit existing text.
