  • A Reusable DRM Module To Be Worked On For "Underserved" Graphics Hardware

    While Kevin Brace of the OpenChrome project as the lead and only developer left working on this open-source VIA driver stack has restarted the discussion towards mainlining the OpenChrome DRM/KMS driver, he has decided to take a break from that for a few weeks and to focus on developing a "reusable DRM module" to help other vintage/obscure graphics hardware.

  • Mesa 18.0.5 release candidate

    The candidate for the Mesa 18.0.5 is now available. Currently we have:
    - 21 queued
    - 0 nominated (outstanding)
    - and 5 rejected patches

  • Mesa 18.0.5 Is The Last Planned Release In The Series

    Mesa 18.0.5 is the last planned point release for the Mesa 18.0 series that debuted at the end of March as the Q1'2018 release for Mesa3D.

    With Mesa 18.1 having been released earlier this month and on schedule, the Mesa 18.0 lifespan is relatively short with Mesa 18.1.1 now due for release in the days ahead. As such, the Mesa 18.0.5 release due out by the end of the week is their last planned maintenance release for this previous quarter's branch.

Software: HandBrake, Plex Media Player, zchunk, Qalculate! and Cherrytree

Filed under
Software
  • HandBrake FFmpeg, no more Nvidia 32 bit drivers

    HandBrake has been updated again to track the master branch, as it now uses FFMpeg 4 and no longer libAV 12. This could probably lead to other improvements, like NVENC/CUDA support, more formats, etc.

    Starting with the Nvidia drivers version 396.24 there will be no more 32 bit support, the driver will be 64 bit only. The 32 bit libraries are still included, so Steam and other applications will keep on being supported.

  • Plex Media Player is back!

    Just a small post to notify that Plex Media Player package is back. Now it does not require Conan or Python anymore for building, and you can just build it using standard tools, the dependency issues between the Plex binary packages have been resolved.

  • What is zchunk?

    Over the past few months, I’ve been working on zchunk, a compression format that is designed to allow for good compression, but, more importantly, the ability to download only the differences between an old version of the file and a new version.

    The concept is similar to both zsync and casync, but it has some important differences. Let’s first look at how downloading a zchunk file works.

  • Qalculate! – The Best Calculator Application in The Entire Universe

    I have been a GNU-Linux user and a Debian user for more than a decade. As I started using the desktop more and more, it seemed to me that apart from few web-based services most of my needs were being met with desktop applications within Debian itself.

    One of such applications was the need for me to calculate between different measurements of units. While there are and were many web-services which can do the same, I wanted something which could do all this and more on my desktop for both privacy reasons as well as not having to hunt for a web service for doing one thing or the other. My search ended when I found Qalculate!.

  • Cherrytree – A Feature-Rich Wiki-Style Note-Taking App

    I recently wrote on Thetapad and Zim – both are excellent note-taking applications with their specialty geared towards different users. Today, thanks to suggestions from FossMint readers, I introduce to you Cherrytree.

    Cherrytree is a free and open source note-taking application with wiki-style text formatting, syntax highlighting, and advanced customizability settings.

    Its advanced search function allows you to locate files across the file tree irrespective of their location. It supports keyboard shortcuts, importing and exporting notes, syncing with cloud services like Dropbox, rich text formatting, and password protection to keep your notes secure.

Linux
Ubuntu

Dubbed "Diamond" and powered by the Linux 4.15 kernel series from the Ubuntu 18.04 LTS (Bionic Beaver) operating system, Linux Lite 4.0 series launches officially today as the first release to drop support for 32-bit installations, bringing numerous updated components, new features and major design changes that include new system theme (Adapta) and icon sets (Papirus).

"Faenza icons were dropped as it had not been maintained in some time (albeit there is a fork) and the same for the Arc theme, development seems to have stalled there," said Jerry Bezencon in the release announcement. "Most of our approach to theming in Series 4.x follows the popular Flat design focus. We also now use the Openzone mouse theme."

Desktop Consolidation Gives SparkyLinux a Clearer Focus

Linux
Reviews

You can run SparkyLinux from a thumb drive. You also can supercharge its performance by loading it into your computer's RAM.

However, the OS is not really as useful if you use it only for a portable computing platform. It performs best when installed on the hard drive. SparkyLinux does not use a frugal installation and special antics to provide persistent memory.

SparkyLinux is a very functional Linux OS. It is a solid choice for use as an all-purpose home edition with all the tools, codecs, plugins and drivers preinstalled.

How open source supports CERN's Large Hadron Collider

Filed under
Server
OSS

The 27-kilometre-long Large Hadron Collider (LHC) buried beneath the France-Switzerland border near Geneva is best known for helping to prove the existence of the Higgs' Boson particle - otherwise known as the God particle - crucial to the Standard Model of particle physics.

The LHC, which uses superconducting magnets to steer beams through its long pipes at just below the speed of light, is supported by open source IT systems at CERN to crunch through about 60 petabytes of data a year. These are built with Openstack, a free and open source software platform for building clouds.

The Openstack cloud first went into production at CERN in July 2013, marking the 13,000-physicist-strong laboratory as an early adopter. Today it has scaled to roughly 300,000 cores – and it's this kind of high-powered, scalable, open source cloud computing that got the attention of many private enterprises, now contributing to the code.

Programming/Development: C++, Go, Mozilla/Firefox and Python

  • 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.
