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.)

Hands-on: A walk through the openSUSE Leap 42.3 installer

Filed under
SUSE

I wrote about the latest openSUSE Leap release a few days ago. In that post, I included some details about upgrading an existing openSUSE Leap installation to the new release. Since then, I have performed a fresh installation on another of my systems (the Acer Aspire V), so in this post I am going to include screenshots and a brief description of the installation process.

First, let's repeat some of the basic information about this release. The release announcement on the openSUSE website gives a bit of information (and a lot of propaganda) about the new release.The release notes contain a lot more technical detail, so be sure to read them before starting.

  • Alpha Store litebook laptop Linux review

    I ordered a litebook after emailing back and forth questions about Linux and the product. They replied super fast and everything sounded great.

    In reality, if I had to guess what is happening, it's a couple teenagers working out of their moms basement, ordering laptops from aliexpress in bulk, installing Linux and then selling them for a profit.

  • Coming Soon | For The Record

    Are we too dependent our Internet connectivity? Should we instead, explore creating our own Linux media servers in place of common streaming services? I’ll give you a preview of my effort to reduce my reliance with common streaming services. I’ll talk about upcoming videos featuring Plex, Kodi, Ubooquity, Subsonic, calibre and more!

Linux 4.13 RC3 Released, Torvalds Curses

Filed under
Linux
  • Linux 4.13-rc3

    Another week, another rc.

    Usually rc2 is the really quiet one, but this release cycle rc2 was
    fairly busy and it made me worry a bit about whether there was
    something bad going on with 4.13.

    But no, it was just random timing, and people got started sending in
    fixes early, and this release cycle it's rc3 that is small. It's about
    half the size (in commits) of rc2 - usually things are the other way
    around. Maybe people are starting to go on vacation (August tends to
    be quiet in Europe in particular).

    I'm not complaining. Quiet weeks are nice.

  • Linux 4.13-rc3 Kernel Released: It's A Small One
  • Linus Torvalds pens vintage 'f*cking' rant at kernel dev's 'utter BS'

    Linux overlord Linus Torvalds has fired off an expletive-laden rant of the sort that only he seems to find acceptable.

    His post to the Linux Kernel mailing list takes aim at a chap named Kees Cook, who The Register believes to be a Google employee working on security for the company's Pixel phones.

    Cook appears to have earned Torvalds' ire with his post warning of a bug in the way the Linux kernel deals with memory leaks.

    Torvalds' response is stern, kicking off with “Kees, stop this idiocy already”, explaining that the bugs Cook discusses are false positives and then launching into “ it's a f*cking disgrace that you are in denial about the fact that it's the *checking* that is broken, not the code, and are making excuses for shit.”

New Features Of Mesa 17.2, Mesa 17.2 Reaches RC2

  • The New Features Of Mesa 17.2

    Mesa 17.2 will be officially released in one or two weeks, so here's a recap of all the improvements made to this open-source 3D Linux driver stack over the past quarter.

    Mesa 17.2 continues with complete OpenGL 4.5 support for Intel i965 and RadeonSI while offering partial OpenGL 4.6 support. Hopefully for Mesa 17.3 next quarter we will see OpenGL 4.6 compliance.

  • Mesa 17.2 RC2 Released

    The second release candidate of Mesa 17.2 is now available for testing.

    Emil Velikov has just released Mesa 17.2 RC2 as the latest weekly build of what should become the next quarterly Mesa 3D stable release in one or two weeks, pending how last minute bug squashing goes. With RC2, RadeonSI should be back to working with Steam and no longer crashing.

  • [Mesa-dev] [ANNOUNCE] mesa 17.2.0-rc2

    The second release candidate for Mesa 17.2.0 is now available.

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

Red Hat and SUSE Leftovers

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.
  • Red Hat named HPE’s Partner of the Year at HPE Discover 2019
    For more than 19 years, Red Hat has collaborated with HPE to develop, deliver and support trusted solutions that can create value and fuel transformation for customers. Our work together has grown over these nearly two decades and our solutions now include Linux, containers and telecommunications technologies, to name just a few. As a testament to our collaboration, HPE has named Red Hat the Technology Partner of the Year 2019 for Hybrid Cloud Solutions.
  • Demystifying Containers – Part II: Container Runtimes
    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
  • Edge > Core > Cloud: Transform the Way You Want
    For more than 25 years, SUSE has been very successful in delivering enterprise-grade Linux to our customers. And as IT infrastructure has shifted and evolved, so have we. For instance, we enabled and supported the move to software-defined data centers as virtualization and containerization technologies became more prevalent and data growth demanded a new approach.
  • SUSE OpenStack Cloud Technology Preview Takes Flight
    We are pleased to announce that as of today we are making a technology preview of a containerized version of SUSE OpenStack Cloud available that will demonstrate a future direction for our product. The lifecycle management for this technology preview is based on an upstream OpenStack project called Airship, which SUSE has been using and contributing to for some time. This follows our open / open policy of upstream first and community involvement.
