Google brings Linux applications to Chromebooks

Support for Linux will enable you to create, test and run Android and web app for phones, tablets and laptops all on one Chromebook. Run popular editors, code in your favorite language and launch projects to Google Cloud with the command-line. Everything works directly on a Chromebook.

Linux runs inside a virtual machine that was designed from scratch for Chromebooks. That means it starts in seconds and integrates completely with Chromebook features. Linux apps can start with a click of an icon, windows can be moved around, and files can be opened directly from apps.

It's official now.

Bring your own Linux to Windows

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).

Neat.

Linux ported to Nintendo Switch

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.

I'm surprised it even took this long.

The oldest x86 processor still supported by a modern Linux kernel?

What is the oldest x86 processor that is still supported by a modern Linux kernel in present time?

I asked the above quiz question during the Geekcamp tech conference in Nov 2017 during my emcee role. The theoretical answer as you can glean from the title of this post is the 486 which was first released in 1989. I determined that fact from this article where support for the 386 was dropped in Dec 2012.

To get you interested, here is the result of my effort.

Cool project.

Interactive X Linux desktop rendered to TTY and streamed over SSH

I'm travelling around the world and sometimes I don't have very good Internet. If all I have is a 3kbps connection tethered from my phone then it's good to SSH into my server and browse the web through elinks. That way my server downloads the web pages and uses the limited bandwidth of my SSH connection to display the result. But it lacks JS support and all that other modern HTML5 goodness. Texttop is simply a way to have the power of a remote server running a desktop, but interfaced through the simplicity of a terminal and very low bandwidth.

Why not VNC? Well VNC is certainly one solution but it doesn't quite have the same ability to deal with extremely bad Internet. Texttop uses MoSH to further reduce the bandwidth and stability requirements of the connection. Mosh offers features like automatic reconnection of dropped connections and diff-only screen updates. Also, other than SSH or MoSH, Texttop doesn't require a client like VNC. But of course another big reason for Texttop is that it's just very cool geekery.

How to set up a Pixelbook for programming

Well, I've really done it. I've taken a pure and unsullied Google Pixelbook, which at one time was fast and secure in all ways, and made it into a crashy mess. My crime? The desire to code.

I'm going to walk you through my process for converting this machine into something that's marginally desirable for programming, but I just wanted to warn you before I begin: this isn't easy, clean, intuitive, or practical. There are rumors that Google is working on better ways to make Chrome OS a host for other flavors of Linux or Linux apps, but right now we're basically working with hacks, and hacks hurt.

Because these hacks hurt, I'd implore you to read this entire guide before attempting any of the steps so you know what you're getting yourself into, and if you, in fact, desire the results.

I think the PixelBook is a stunningly beautiful and fast machine, and while Chrome OS isn't nearly as useless as people often think it is, it clearly isn't the kind of operating system many OSNews readers would prefer. This is a guide to getting a traditional Linux setup up and running.

RISC-V port merged to Linux

The RISC-V port was just merged to Linux a few minutes ago. This means we will be in the 4.15 release, which should be out about 10 weeks from last Sunday. As soon as the tarballs are created, the RISC-V Linux ABI will be stable, and since we'll ideally be in a glibc release that comes out soon after that we'll be fully ABI stable by early in February.

RISC-V is a completely free and open ISA that hasn't seen much adoption just yet.

The rise and fall of LiMux

The LiMux (or Limux) initiative in Munich has been heralded as an example of both the good and bad in moving a public administration away from proprietary systems. Free Software Foundation Europe (FSFE) President Matthias Kirschner reviewed the history of the initiative - and its recent apparent downfall - in a talk at Open Source Summit Europe in Prague. He also looked at the broader implications of the project as well as asking some questions that free-software advocates should consider moving forward.

The LiMux initiative is one of the longest-running story 'streams' on OSNews. The oldest item I could find is from 2003.

100 days of postmarketOS

We talked about postmarketOS back in late May, and this weekend the project published a summary of all the work they've done over the past 100 days.

What you see here is only the tip of the iceberg. So much work has gone into fixing bugs, and little improvements, that it would be ridiculous to go through the effort and list them all. The community has grown so fast in such a short time and we have people with all kinds of skills on board, ranging from Linux experts to kernel hackers to people who reverse engineer bootloaders (hi @McBitter!). We collaborate with people from other projects as well, such as @pavelmachek, who is close to using his N900 as a daily driver with his own distribution, recently just reached out to us.

So if you read through the whole post, you are probably interested in what we do. Consider contributing to the project, the entry barrier is really low. pmbootstrap automates everything for you and we are more than happy to help you through any issues you encounter in the chat. There are also a lot of opportunities to help with development, so there's plenty to do. And plenty of fun to have.

That's a lot of work for just 100 days.

Build your own Linux

This course walks through the creation of a 64-bit system based on the Linux kernel. Our goal is to produce a small, sleek system well-suited for hosting containers or being employed as a virtual machine.

Because we don't need every piece of functionality under the sun, we're not going to include every piece of software you might find in a typical distro. This distribution is intended to be minimal.

Building my own Linux installation from scratch has always been one of those things I've wanted to do, but never got around to. Is this still something many people do? If so, why?

Review: System76’s Galago Pro

Ars Technica:

The Galago Pro was my daily machine for about a month. While I had some issues as noted above (I don't like the trackpad or the keyboard), by and large it's the best stock Linux machine. The only place where the Dell XPS 13 blows it out of the water is in battery life. As someone who lives full time in an RV and relies on a very limited amount of solar power (300w) for all my energy needs, that battery life is a deal breaker. But in nearly every other regard, this is by far my favorite laptop, and I wouldn't hesitate to recommend it.

There is something that comes up in the comments of nearly every review of System76 hardware, and that's how the company doesn't build its own hardware. System76 orders everything from upstream hardware vendors, and, in the case of the Galago Pro, that would be the Clevo N130BU (or N131BU). I've never quite understood what the issue is, but it certainly seems to rub some people the wrong way. Could you save a couple bucks by ordering the Clevo directly? Sure, but you'd have no support, no custom PPA to fix hardware issues, and no community to get involved in. If you just want a dirt-cheap Linux rig, try eBay. What System76 offers is great Linux experience with a piece of hardware that's maybe not the absolute cheapest hardware.

However, that is going to change. In addition to launching its own don't-call-it-a-distro OS, the company has announced that will soon begin what it calls "phase three" - moving its product design and manufacturing in-house. There, it hopes to "build the Model S of computers." It's a bold move, starting up hardware manufacturing and an operating system at the same time. It's the kind of plan that might well lead to overextending oneself (after all, even Canonical has backed away from making its own desktop OS).

I'm genuinely curious what System76's in-house Linux laptop will be like.

postmarketOS: aiming for a 10 year life-cycle for smartphones

It is 2017. Pick an average PC from 2007 and install a minimal GNU/Linux based operating system. You will be able to do basic computing tasks (eg. surfing the web, reading E-Mails, listening to music, chatting) just like on an expensive modern PC. You will even get security updates, so your old computer is protected, just like as a new one.

postmarketOS (I love the name) aims to do the same for smartphones. A small Linux distribution with a phone interface, designed to be easy to update and maintain to solve the problems Android poses in this area. The project is in its infancy, so it needs a lot of help to further realise its vision.

This is a great idea, and it could breathe life into devices not even LineageOS can keep alive.

Linux 4.11 released

Linux 4.11 has been released. This release adds support for pluggable IO schedulers framework in the multiqueue block layer, journalling support in the MD RAID5 implementation that closes the write hole, a more scalable swapping implementation for swap placed in SSDs, a new statx() system call that solves the deficiencies of the existing stat(), a new perf ftrace tool that acts as a frontend for the ftrace interface, support for drives that implement the OPAL Storage Specification, support for the Shared Memory Communications-RDMA protocol as defined in RFC7609, persistent scrollback buffers for all VGA consoles, and many other improvements and new drivers. Here is the full list of changes.

Linux 4.10 released

Linux 4.10 has been released. This release adds support for virtualized GPUs, a new 'perf c2c' tool for cacheline contention analysis in NUMA systems, a new 'perf sched timehist' command for a detailed history of task scheduling, improved writeback management that should make the system more responsive under heavy writing load, a new hybrid block polling method that uses less CPU than pure polling, support for ARM devices such as the Nexus 5 & 6 or Allwinner A64, a feature that allows to attach eBPF programs to cgroups, an experimental MD RAID5 writeback cache, support for Intel Cache Allocation Technology, and many other improvements and new drivers. Here is the full list of changes.

Bored with ho-hum cloud backups? Use Usenet instead

Unfortunately, this kind of service isn' t free, and the cost can be a barrier. However, there is a cost-effective way to store your cloud backups: Usenet. With access to a Usenet news server, you can simply upload your backup there, and it will be stored redundantly in news servers all over the world. Best of all, this approach typically costs considerably less than a cloud backup service.

Obviously, this is not your typical method of cloud storage. Many may snicker or find it plain weird to tap into this vintage part of the Internet in such a modern way. But oddly enough, we have experience experimenting with this alternative offline storage when it comes to backing up a Linux system. And backing up your Linux system to usenet ultimately requires only a handful of steps. It's not only possible - it's scriptable, too.

I didn't know this was possible, but that's mostly because I never thought of it. Clever.

Finding an alternative to macOS, part 2: adventures with Linux

This is the second in my series on finding an alternative to Mac OS X. Part 1 was about evaluating 13 alternative operating systems and then choosing one to use full time. The selected OS was elementary OS. The motivation for this change is to get access to better hardware since Apple is neglecting the Mac lineup.

If video is more your style I gave a short (10 min) talk at work on my adventures with Linux that covers the core content of this post.

This impromptu series is a great read. It's positive, focused on solutions instead of complaints, and is an honest effort to expand horizons and try out new and different (to the author) approaches to using his computer.

Linux and Steam running on PS4 firmware 4.0

Marcan42 of Fail0verflow fame was at the CCC33 event this year, to explain how Fail0verflow exploited the PS4 hardware in order to run Linux on the PS4.

The presentation goes back to all the pain the hackers had to go through in order to make Linux compatible with the PS4 architecture, which Marcan42 described several times throughout the presentation as "not being a PC" as it lacks lots of the legacy architecture bits required for a computer to constitute what is known today as an IBM compatible PC.

Be sure to watch the actual presentation. It's quite informative and detailed.

Pixel for PC and Mac

PIXEL represents our best guess as to what the majority of users are looking for in a desktop environment: a clean, modern user interface; a curated suite of productivity software and programming tools, both free and proprietary; and the Chromium web browser with useful plugins, including Adobe Flash, preinstalled. And all of this is built on top of Debian, providing instant access to thousands of free applications.

Put simply, it's the GNU/Linux we would want to use.

The Raspberry Pi's "own" Linux distribution is now also available for Windows and Mac - i.e., a live image you can run on your PC.

System76 Oryx Pro: Linux on a laptop has never been better

If you wanted a portable video editing workstation or a gaming machine you can take with you wherever you go, you'd be hard pressed to find more impressive specs from any manufacturer, let alone one that ships with Linux-compatible hardware like System76. So I mentioned to System76 that I wanted to test the Oryx Pro and compare it to the Dell XPS as a "developer" laptop. Frankly, the company was a little hesitant, pointing out that the two aren't really - aside from both shipping with Ubuntu installed - at all alike. And soon after the Oryx Pro arrived, I really understood just how different these machines area.

System76 has really become a household name in Linux circles for great machines with fantastic out-of-the-box Linux support.

Microsoft joins the Linux Foundation

The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announced that Microsoft has joined the organization at a Platinum member during Microsoft's Connect(); developer event in New York.

For those of us who witnessed the Microsoft of the late '90s and early 2000s, this is yet another one of those "the industry has really changed" moments.
