Like the various Linux server and desktop distributions, the container-oriented Linux distributions mix and match various projects and components to construct a complete container infrastructure.

These distros generally combine a minimal OS kernel, an ...
Like FreeBSD Jails and Solaris Zones, Linux containers are self-contained execution environmentsmdash;with their own, isolated CPU, memory, block I/O, and network resourcesmdash;that share the kernel of the host operating system.

The result is something that feels like a virtual machine, but sheds all the weight and startup overhead of a guest operating system.In a large-scale system, running VMs would mean you are probably running many duplicate instances of the same OS and many redundant boot volumes.

Because containers are more streamlined and lightweight compared to VMs, you may be able to run six to eight times as many containers as VMs on the same hardware.To read this article in full or to leave a comment, please click here
Microsoft says an attacker needs kernel-level access before they can use the 'GhostHook' technique to install a rootkit.
Researchers at CyberArk have developed a bypass for Windows PatchGuard that leverages Intel's Processor Trace (Intel PT) technology to execute code at the kernel.
The LinuxKit project is now incubating several technologies to advance Linux security, including the Wireguard VPN and Landlock security efforts.
Moto G4 and Moto G5 model Motorola phones are vulnerable to kernel command line injection vulnerabilities.
Last year Intel became a Python distributor, offering its own edition of the language outfitted with Intel's Math Kernel Library (MKL). MKL accelerates data-science-related tasks by using Intel-specific processor extensions to speed up certain operations, a fine fit for a language that has become a staple in machine learning and math-and-stats circles.The Intel Distribution of Python, a repackaging of Continuum Analytics's Anaconda distribution, incorporated MKL support to give Python data science and machine learning packages a boost. Now ActiveState, producers of an enterprise-grade Python, (as well as Ruby, Node.js, and Golang distributions) has brought MKL into its own Python distro.To read this article in full or to leave a comment, please click here
It's been a long time in the works, but a memory management featurenbsp;intended to give machine learning or other GPU-powered applications anbsp;major performance boostnbsp;is close to making it into one of the next revisions of the kernel.Heterogenous memory management (HMM) allows a devicersquo;s drivernbsp;to mirror the address space for a process under its own memory management. As Red Hat developer Jeacute;rocirc;me Glissenbsp;explains, this makes it easier for hardware devices like GPUs to directly access the memory of a process without the extra overhead of copying anything.
It also doesn't violate the memory protection features afforded by modern OSes.To read this article in full or to leave a comment, please click here
Update has been in beta testing since late March, when iOS 10.3 was released.
Last year Microsoft added an unusual new feature to Windows 10: Linux support.

The Windows Subsystem for Linux (WSL) — sometimes called Bash on Windows — is “Microsoft’s implementation of a Linux-compatible infrastructure that runs atop and within the Windows kernel,” senior program manager Rich Turner tells CIO.com.

That means running Linux binaries without leaving Windows.“Bash on Windows offers a toolset for developers, IT administrators and other tech professionals that want or need to run Linux command-line tools alongside their Windows tools and applications,” Turner explains.

Developed with the help of Canonical (and a large community of Linux users), it’s not there to turn Linux into Windows, or Windows into Linux.
It’s just that some Linux tools are so ubiquitous for development and deployment that it’s useful to be able to use them without spinning up a virtual machine (VM).

That’s one of the reasons Macs are so popular with developers: MacOS is based on BSD, which is Unix, so it can run Linux tools like Bash.

And now, so can Windows 10.To read this article in full or to leave a comment, please click here
Will Google dump Android for Fuchsia? Google’s new Fuchsia operating system doesn’t use the Linux kernel.
Instead the company has created its own microkernel called Magenta.

Google has given the world its first look at Fuchsia, and many people are wondering if the company will eventually replace Android with Fuchsia.Ron Amadeo reports for Ars Technica: With any new project at Google, it's hard to know what the scale of the project will be.
Is this a "20 percent" project that will be forgotten about in a year or something more important? Luckily, we have a direct statement from a Fuchsia developer on the matter.
In the public Fuchsia IRC channel, Fuchsia developer Travis Geiselbrecht told the chat room the OS "isn't a toy thing, it's not a 20% project, it's not a dumping ground of a dead thing that we don't care about anymore."To read this article in full or to leave a comment, please click here
Is Linux kernel design outdated? Linux has made great strides over the years, advancing far beyond where it was when it started.

But one redditor recently wondered if Linux was suffering from outdated kernel design. He asked his question in the Linu...
