  • 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, OCI Unveil Controversial Open Container Industry Standard

Filed under
OS
Server

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.

Reviews

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.

Open-source world resurrects Oracle-free Solaris project OmniOS

Filed under
OS
OSS

The open-source community has fought back and resurrected the development of OmniOS – an Oracle-free non-proprietary variant of Solaris, which had been shelved in April.

The development of OmniOS, a distribution of Illumos derived from Sun's open-source flavor of Solaris, was killed after five years of work by web applications biz OmniTI.

It was hoped OmniOS would be community-driven, simple to use, and fast to install and operate. However, the project was axed, as the project failed to make any cash out of the development and a community failed to emerge. Consequently all work stopped and support contracts were not renewed.

Graphics: Mesa 17.2.6 RC, AMDGPU, and Vulkan

  • Mesa 17.2.6 release candidate
  • Mesa 17.2.6 RC Arrives With 50+ Fixes
    While Mesa 17.3 is imminent and should be released as stable within the next few days, Mesa 17.2.6 is being prepped for release as the current point release.
  • 43 More AMDGPU DC Patches Hit The Streets
    While the massive AMDGPU DC infrastructure has been merged for Linux 4.15, the flow of improvements to this display code continues and it looks like the next few kernel cycles at least could be quite busy on the AMD front.
  • A Prototype Of The Vulkan Portability Initiative: Low-Level 3D To Vulkan / D3D12 / Metal
    A Mozilla engineer has put out a prototype library in working on the Vulkan Portability Initiative for allowing low-level 3D graphics support that's backed by Vulkan / Direct3D 12 / Metal. With Apple sticking to their own Metal graphics API and Direct3D 12 still being the dominant graphics API on Windows 10, The Khronos Group has been working towards better 3D portability for where Vulkan may not be directly supported by the OS/drivers or otherwise available. They've been working to target a subset of the Vulkan API that can be efficiently mapped to these other native graphics APIs and to have the libraries and tooling for better compatibility and code re-use of these different graphics APIs.

Kernel: Linux 4.15, TLDR, and Linus Torvalds' Latest Rant

  • Linux 4.15 Adds AMD Raven Ridge Audio ID
    Not only is AMD Stoney Ridge audio (finally) being supported by the Linux 4.15 kernel, but it also looks like Raven Ridge audio should now be working too.
  • Linux 4.14.2 Fixes The BCache Corruption Bug
    Normally I don't bother mentioning new Linux kernel point releases on Phoronix unless there are some significant changes, as is the case today with Linux 4.14.2.
  • TLDR is what Linux man pages always should have been
    If you get stuck using a Linux tool, the first port of call shouldn’t be to Stack Overflow, but rather its “man pages.” Man — which is short for manual — retrieves documentation for a given program. Unfortunately, this can often be dense, hard to understand, and lacking in practical examples to help you solve your problem. TLDR is another way of looking at documentation. Rather than being a comprehensive guide to a given tool, it instead focuses on offering practical example-driven instructions of how something works.
  • Linux creator Linus Torvalds: This is what drives me nuts about IT security
    Developers are often accused of not thinking about security, but Linux kernel founder Linus Torvalds has had enough of security people who don't think about developers and end-users. After blasting some kernel developers last week for killing processes in the name of hardening the kernel, Torvalds has offered a more measured explanation for his frustration with security myopia. While he agrees that having multiple layers of security in the kernel is a good idea, certain ways of implementing it are not, in particular if it annoys users and developers by killing processes that break users' machines and wreck core kernel code. Because ultimately, if there are no users, there's not much point in having a supremely secure kernel, Torvalds contends.

Unity 7 Hoping To Become An Official Flavor For Ubuntu 18.04 LTS

While Canonical abandoned their work on the Unity desktop environment in favor of the Unity-inspired customized GNOME Shell that debuted in Ubuntu 17.10, some within the community have remained interested in maintaining Unity 7 and even getting it into an official spin/flavor of Ubuntu. Posted today to the community.ubuntu.com was a Unity maintenance roadmap, reiterating the hope by some in the Ubuntu community for Ubuntu Unity to become an official LTS distribution of Ubuntu. They are hoping to make it an official flavor alongside Kubuntu, Ubuntu Budgie, Xubuntu, and others. Read more Original/direct: Unity Maintenance Roadmap

Programming/Development: Django and Google India

  • An introduction to the Django ORM
    One of the most powerful features of Django is its Object-Relational Mapper (ORM), which enables you to interact with your database, like you would with SQL. In fact, Django's ORM is just a pythonical way to create SQL to query and manipulate your database and get results in a pythonic fashion. Well, I say just a way, but it's actually really clever engineering that takes advantage of some of the more complex parts of Python to make developers' lives easier.
