The Linux Kernel: An Explanation In Layman’s Terms

Filed under
Linux

There are so many Linux distributions out in the wild, but there is only one de facto thing that they have in common: the Linux kernel. But while it’s often talked about, a lot of people don’t really know exactly what it does.

Let’s take a look at what the Linux kernel really does and why it’s needed, with as few geeky terms as possible.

Alpine 3.0.0 released

Filed under
GNU
Linux

We are pleased to announce Alpine Linux 3.0.0, the first release in v3.0 stable series.

This is the first release with musl libc instead of uClibc and is not ABI compatible with earlier versions, so special care needs to be taken when upgrading. See http://alpinelinux.org/edge-musl on how to upgrade.

In the Matrix of Mobile, Linux Is Zion

Filed under
Linux

In mobile we are losing the free world called the Web and the Net. How do we save it?
Already most of us spend more time on mobile devices than we do on desktops and laptops, put together. We also can do a lot more stuff, in a lot more places, on mobile devices than on computers. There were more than a million iOS apps on the shelves of Apple's store in October 2013, and I'm guessing there are at least that many Android apps on Google's shelves by now.
Meanwhile, app development on computers is slacking off—so is Web development, except as required to accessorize mobile apps. And on mobile devices, use of the Web is fading as well. According to Flurry Analytics, the Web's share of mobile use dropped from 20% in 2013 to 14% in 2014. In "The Decline of the Mobile Web", Chris Dixon writes.

KVM Gets Improved For S390, POWER & MIPS

Filed under
Linux

The KVM virtualization update for Linux 3.16 brings improvements mostly for less common CPU architectures. With the Linux 3.17 kernel should come more interesting work for x86 fans but KVM on IA64 is likely to get the boot.

Paolo Bonzini sent in the Kernel-based Virtual Machine changes this morning for the Linux 3.16 kernel. This pull request brings a lot of changes for IBM's S390 architecture with regard to optimizations, support for migration, GDB support, and other improvements. Within the ARM space the only noteworthy change was support for the PSCI 0.2 hyper-call interface.

After a period when Linux kernel updates were smaller than usual, the developers have started once again to send patches and fixes, even for slightly older kernels, like 3.12.x. This is the most advanced Long Term Support kernel version and it's expected to see more changes than the rest of them.

“I'm announcing the release of the 3.12.21 kernel. All users of the 3.12 kernel series must upgrade.”

Linux
Red Hat

Lennart Poettering has added two new service sandboxing features to systemd.

For improving the security of Linux services, Lennart added ReadOnlySystem and ProtectedHome settings for services. ReadOnlySystem will mount /usr and /boot as read-only for the specific service. The ProtectedHome setting mounts /home and /run/user as read-only or replaces it with an empty, inaccessible directory.

Linux 3.16: New Synaptics Driver, Improved Sony DualShock 4 Driver

Filed under
Linux

The HID/input pull request for the Linux 3.16 merge window has been sent in with some useful additions.

First up for the HID Linux 3.16 pull is an RMI driver, which is for supporting Synaptics RMI4 devices over USB or I2C. The RMI driver right now uses its own RMI4 implementation but will ultimately become a transport driver for the RMI4 library once it's been merged upstream. This driver was developed by Synaptics along with Red Hat and other independent kernel contributors.

Nouveau On Linux 3.16 Will Allow You To Try Re-Clocking

Filed under
Graphics/Benchmarks
Linux

The Nouveau DRM graphics driver for open-source NVIDIA support hasn't seen any fundamental re-clocking support breakthroughs for the upcoming Linux 3.16 kernel but the support can be easily enabled for select GeForce GPU models.

The lucky GPUs where the Nouveau end-user re-clocking can be enabled with the next kernel update is the NV40, NVAA, and NVE0 GPU series. The NV40 chip family is the GeForce 6 and 7 series. The NVAA series meanwhile is part of the NV50 family but consists of just the GeForce 8100/8200/8300 mobile GPUs / nForce 700a series and 8200M G. NVE0 meanwhile is the most interesting of the bunch and consists of the Kepler (GeForce 600/700 series) GPUs. Re-clocking support for other graphics processor generations is still a work-in-progress.

5 fundamental differences between Windows 10 and Linux

This comparison really only scratches the surface. And don't get me wrong, there are areas where Windows 10 bests Linux (few, but they do exist). In the end, however, the choice is yours. Chances are you'll be making the choice based on which platform will allow you get more work done and do so with a certain level of efficiency and reliability. I would highly recommend, to anyone, if Linux can enable you to get your work done...give it a go and see if you don't find it more dependable and predictable. Read more

  • Sony's PlayStation 4 DualShock Controller Now Supported in Fedora Linux, GNOME
    GNOME developer Bastien Nocera talks in his latest blog post about the enhancements he managed to implement in the past few weeks to the Bluetooth stack of the Fedora Linux operating system. The patches submitted by the developer to the Bluetooth packages in the latest Fedora Linux release promise to bring improvements to the way PlayStation 3 DualShock controllers are set up in the environment if you're using the GNOME desktop environment. Until now, to set up a DualShock 3 controller, users had to plug it in via USB, then disconnect it, and then press the "P" button on the joypad, which would have popped-up a dialog to confirm the Bluetooth connection. But this method had some quirks though.

Debian Development Reports

  • Free software log (July and August 2017)
    August was DebConf, which included a ton of Policy work thanks to Sean Whitton's energy and encouragement. During DebConf, we incorporated work from Hideki Yamane to convert Policy to reStructuredText, which has already made it far easier to maintain. (Thanks also to David Bremner for a lot of proofreading of the result.) We also did a massive bug triage and closed a ton of older bugs on which there had been no forward progress for many years. After DebConf, as expected, we flushed out various bugs in the reStructuredText conversion and build infrastructure. I fixed a variety of build and packaging issues and started doing some more formatting cleanup, including moving some footnotes to make the resulting document more readable.
