Android devices are based on the Linux kernel but, since the beginning, those devices have not run mainline kernels. The amount of out-of-tree code shipped on those devices has been seen as a problem for most of this time, and significant resources have been dedicated to reducing it. At the 2018 Linux Plumbers Conference, Sandeep Patil talked about this problem and what is being done to address it. The dream of running mainline kernels on Android devices has not yet been achieved, but it may be closer than many people think.

Samsung debuted DeX last year to make your phone behave a bit more like a computer when plugged into a monitor. This year, DeX functionality has improved so you don't need to expensive custom dock, just a video cable. At Samsung's developer conference last week, it announced DeX would also get full Linux support. It's only officially available to those in the beta program, but we've got the APK.

Nitrux is a Linux distribution based on Ubuntu suitable for laptops and desktop computers. Nitrux provides all the benefits of the Ubuntu operating system combined with a focus on portable, redistributable application formats like AppImages. Nitrux uses the LTS branch of Ubuntu as a basis using only the core system and then slowly building up to ensure a clean user experience. Nitrux is suitable for newcomers to Linux as well as *nix experienced users. Nitrux uses KDE Plasma 5 and KDE Applications; we also use our in-house software suite Nomad Desktop adding to the user experience.

In recent years, three different distribution independent package formats have gained a lot of popularity. There are already a few Linux distributions like Endless OS and Fedora Silverblue that depend solely on distribution independent packages to run desktop applications. Are these package formats ready to become main packages formats for Linux distributions?

In this article we will take a look at the advantages and disadvantages of each package format individually, and of distribution independent package formats in general.

It would be reasonable to expect doing nothing to be an easy, simple task for a kernel, but it isn't. At Kernel Recipes 2018, Rafael Wysocki discussed what CPUs do when they don't have anything to do, how the kernel handles this, problems inherent in the current strategy, and how his recent rework of the kernel's idle loop has improved power consumption on systems that aren't doing anything.

This is my reality. I am not an emotionally empathetic kind of person and that probably doesn't come as a big surprise to anybody. Least of all me. The fact that I then misread people and don't realize (for years) how badly I've judged a situation and contributed to an unprofessional environment is not good.

This week people in our community confronted me about my lifetime of not understanding emotions. My flippant attacks in emails have been both unprofessional and uncalled for. Especially at times when I made it personal. In my quest for a better patch, this made sense to me. I know now this was not OK and I am truly sorry.

The above is basically a long-winded way to get to the somewhat painful personal admission that hey, I need to change some of my behavior, and I want to apologize to the people that my personal behavior hurt and possibly drove away from kernel development entirely.

I am going to take time off and get some assistance on how to understand people’s emotions and respond appropriately.

PowerShell Core from Microsoft is now available for Linux as a Snap. Built on the .NET Framework, PowerShell is an open source task-based command-line shell and scripting language with the goal of being the ubiquitous language for managing hybrid cloud assets. It is designed specifically for system administrators and power-users to rapidly automate the administration of multiple operating systems and the processes related to the applications that run on those operating systems.

For reasons beyond the scope of this entry, today I feel like writing down a broad and simplified overview of how modern Linux systems boot. Due to being a sysadmin who has stubbed his toe here repeatedly, I'm going to especially focus on points of failure.

FBGraphics was made to produce fullscreen pixels effects easily with non-accelerated framebuffer by leveraging multi-core processors, it is a bit like a software GPU (much less complex and featured!), the initial target platform is a Raspberry PI 3B and extend to the NanoPI (and many others embedded devices), the library should just work with many others devices with a Linux framebuffer altough there is at the moment some restrictions on the supported framebuffer format (24 bits).

FBGraphics is lightweight and does not intend to be a fully featured graphics library, it provide a limited set of graphics primitive and a small set of useful functions to start doing framebuffer graphics right away with or without multi-core support.

One of the ongoing system administration controversies in Linux is that there is an ongoing effort to obsolete the old, cross-Unix standard network administration and diagnosis commands of ifconfig, netstat and the like and replace them with fresh new Linux specific things like ss and the ip suite. Old sysadmins are generally grumpy about this; they consider it yet another sign of Linux's 'not invented here' attitude that sees Linux breaking from well-established Unix norms to go its own way. Although I'm an old sysadmin myself, I don't have this reaction. Instead, I think that it might be both sensible and honest for Linux to go off in this direction. There are two reasons for this, one ostensible and one subtle.

Have you ever tried to install Minecraft and seen an error message like, "This application requires a Java Runtime Environment 1.6.0"? Or you try to install something on Windows, and you get an error that says some .NET framework is missing? Or, as a more basic example, have you ever spent a couple hours setting up a new computer with all your applications and preferences?

Those are the kinds of problems Docker, and "containers" more broadly (Docker is kind of the Kleenex of containers), are meant to solve. Docker makes it easy to install Linux applications on servers, along with their required dependencies and whatever preferences you might have for those applications. And, as an added bonus, conflicting dependencies between applications (maybe one app relies on Python 2, and another app relies on Python 3) aren't an issue, because everything is isolated in different containers.

After starting with Ubuntu, Microsoft has added a number of Linux distributions to its Windows Subsystem for Linux (WSL) Linux runtime environment. A Windows machine can simultaneously offer an Ubuntu, SUSE, Debian, and Kali "personality," providing users with a choice of the different distributions' preferences and package management.

But if your distribution isn't yet available or if you want a Linux installation that's customized just the way you like it, there's now an answer: Microsoft has an open source tool for building your own Linux package. The tool is aimed at two groups: distribution owners (so they can produce a bundle to ship through the Microsoft Store) and developers (so they can create custom distributions and sideload them onto their development systems).

There are two major reasons I can think of to hack a game console. The first one is obvious: so you can play cracked copies of games. That’s why modern consoles are so difficult to hack, because millions of dollars are on the line.

But some people just want to run any software they choose on the hardware they own. And for those people, Linux on the Switch is a huge achievement.
