RancherOS: A tiny Linux for Docker lovers

Filed under
OS

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 orchestration framework, and an ecosystem of container services. RancherOS not only fits the mold, but takes the minimal kernel and the container paradigm to extremes.

Open-spec audio streaming SBC runs Linux on a 996MHz i.MX6 ULL

Linux

PolyVection’s “VoltaStream Zero” is an audio streaming SBC that runs Linux on a 996MHz i.MX6 ULL, and offers a TI PCM5121 DAC, TOSLINK, USB, and WiFi.

In 2013, Berlin based software developer Philip Voigt decided to build his own music streaming system. As detailed in this blog entry, Voight started with a Raspberry Pi, but decided it lacked the features he needed. He then tried working with a BeagleBone design, but found the board too complex and expensive — especially the prospect of duplicating the 6-layer PCB. Voight also evaluated several computer-on-module based designs, but after playing around with a vastly improved KiCAD PCB design and layout package, he decided to build an SBC from scratch.

  • IncludeOS: a unikernel for C++ applications

    Is it truly an efficient use of cloud computing resources to run traditional operating systems inside virtual machines? In many cases, it isn't. An interesting alternative is to bundle a program into a unikernel, which is a single-tasking library operating system made specifically for running a single application in the cloud. A unikernel packs everything needed to run an application into a tiny bundle and, in theory, this approach would save disk space, memory, and processor time compared to running a full traditional operating system. IncludeOS is such a unikernel; it was created to support C++ applications. Like other unikernels, it is designed for resource-efficiency on shared infrastructure, and is primarily meant to run on a hypervisor.

    Frequently, virtual machines end up running a full server operating system, though the entire instance is devoted to running only a few applications or even just one. However, every running instance on a physical machine means a full set of services and binaries that's unnecessarily replicated. Unikernel developers take the opportunity to aggressively pare down the operating system to a bare minimum. Unikernels are at the extreme end of the possible answers to the question "how small can you make an operating system?" A unikernel is an instance of a single program "baked together" with a small library that provides the operating system and acts as an interface to the (virtual) hardware.

Qubes OS 4.0-rc1 has been released!

Filed under
OS

No doubt this release marks a major milestone in Qubes OS development. The single most import undertaking which sets this release apart, is the complete rewrite of the Qubes Core Stack. We have a separate set of posts detailing the changes (Why/What/How), and the first post is planned to be released in the coming 2 weeks.

This new Core Stack allows to easily extend the Qubes Architecture in new directions, allowing us to finally build (in a clean way) lots of things we’ve wanted for years, but which would have been too complex to build on the “old” Qubes infrastructure. The new Qubes Admin API, which we introduced in a recent post, is a prime example of one such feature. (Technically speaking, we’ve neatly put the Admin API at the heart of the new Qubes Core Stack so that it really is part of the Core Stack, not merely an “application” built on top of it.)

FreeRTOS-based remote I/O module offers isolated interfaces

Filed under
OS

Artila’s “RIO-2014PG” remote I/O module runs FreeRTOS on an Atmel SAM4E16E, and offers isolated Fast Ethernet, RS485, and analog and digital I/O.

Artila Electronics, which is known primarily for its embedded Linux industrial computers such as the Matrix-700 and Matrix-710 IoT gateway, has more recently been getting into embedded gear that runs the open source FreeRTOS. The new RIO-2014PG uses the same 120MHz, 32-bit Cortex-M4 SAM4E16E MCU as last year’s RIO-2015PG.

CoreOS and the Open Container Initiative on Wednesday introduced image and runtime specifications largely based on Docker's image format technology.

However, OCI's decision to model the standard on Docker's de facto platform has raised questions. Some critics have argued for other options.

Version 1.0 provides a stable standard for application containers, according to Brandon Philips, CTO at CoreOS and chair of the OCI Technical Oversight Board.

We want a nice looking distro, don’t we? We want a distro that does the best work when it comes to stability. Don’t we? Here we come across NeptuneOS, a Linux distro based on Debian with KDE desktop environment. As we all know when it comes to stability, there are a lot of fewer distros that can match Debian. Also being based on Debian, the number of compatible software increase a lot.

Qt/KDE: Qt5 in Debian and Slackware, QtCreator on Android, KDE Discover, and Plasma's 10th Anniversary

  • moving Qt 4 from Debian testing (aka Buster): some statistics, update II
    We started filing bugs around September 9. That means roughly 32 weeks which gives us around 5.65 packages fixed per week, aka 0.85 packages per day. Obviously not as good as we started (remaining bugs tend to be more complicated), but still quite good.
  • [Slackware] Plasma5 – April 18 edition for Slackware
    The KDE-5_18.04 release of ‘ktown‘ for Slackware-current offers the latest KDE Frameworks (5.45.0), Plasma (5.12.4) and Applications (18.04.0). The Qt5 was upgraded to 5.9.5. Read the README file for more details and for installation/upgrade instructions. Enjoy the latest Plasma 5 desktop environment.
  • Perfect Debugging Experience with QtCreator on Android
    While I was working on a yet-to-be-announced super secret and cool Qt on Android project, I had to do a lot of debugging. This way I found that debugging Qt apps on Android using QtCreator was ok, but it had some issues, which was kinda frustrating.
  • Discover – Easily Install Software on KDE Neon Desktop
    KDE Discover is an Open Source GUI app installer that comes packaged with KDE Neon. It was particularly built from the ground up to be compatible with other modern Linux distros with emphasis on beauty and convenience. KDE Discover was also designed to allow for an intuitive User Experience as it features a clean and clear layout with a high readability value which makes it easy to browse, search for, install, and uninstall applications.
  • Almost 10 years of Plasma-Desktop
    Last week I was at work and start to listen my boss said: “We need to show this to our director”. So I went to my coworker table to see what was happening. So they were using Gource to make a video about the git history of the project. Gource is a software version control visualization tool. So that triggered in my mind some memories about a friend talking about Python and showing how the project as grow in this past years, but I never discovered about the tool that made that amazing video. So well, I started to make some Gource videos, and because my love about KDE Community, why not make one about it?

GNOME: Getting Real GNOME Back in Ubuntu 18.04, Bug Fix for Memory Leak

  • Getting Real GNOME Back in Ubuntu 18.04 [Quick Tip]
    Ubuntu 18.04 uses a customized version of GNOME and GNOME users might not like those changes. This tutorial shows you how to install vanilla GNOME on Ubuntu 18.04. One of the main new features of Ubuntu 18.04 is the customized GNOME desktop. Ubuntu has done some tweaking on GNOME desktop to make it look similar to its Unity desktop. So you get minimize options in the windows control, a Unity like launcher on the left of the screen, app indicator support among some other changes.
  • The Infamous GNOME Shell Memory Leak
    at this point, I think it’s safe to assume that many of you already heard of a memory leak that was plaguing GNOME Shell. Well, as of yesterday, the two GitLab’s MRs that help fixing that issue were merged, and will be available in the next GNOME version. The fixes are being considered for backporting to GNOME 3.28 – after making sure they work as expected and don’t break your computer.
  • The Big GNOME Shell Memory Leak Has Been Plugged, Might Be Backported To 3.28
    The widely talked about "GNOME Shell memory leak" causing excessive memory usage after a while with recent versions of GNOME has now been fully corrected. The changes are currently staged in Git for what will become GNOME 3.30 but might also be backported to 3.28. Well known GNOME developer Georges Stavracas has provided an update on the matter and confirmed that the issue stems from GJS - the GNOME JavaScript component - with the garbage collection process not being fired off as it should.
