  • 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.

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."

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: GNOME, CI/CD, Go and Qt

  • Bilal Elmoussaoui: libhandy-rs v0.6.0 is out!

    Recently I kind of took over the maintainership of libhandy-rs, the Rust bindings of libhandy. I have since then been preparing for a new release so that Rust & GTK app developers can update to the latest gtk-rs release as soon as possible. I also heavily depend on it on my various little apps.

  • Easily speed up CI by reducing download size

    Every time a CI pipeline runs on GitLab, it downloads the git repository for your project. Often, pipeline jobs are set up to make further downloads (of dependencies or subprojects), which are also run on each job.

  • What you need to know about automation testing in CI/CD

    Test automation means focusing continuously on detecting defects, errors, and bugs as early and quickly as possible in the software development process. This is done using tools that pursue quality as the highest value and are put in place to ensure quality—not just pursue it. One of the most compelling features of a continuous integration/continuous delivery (CI/CD) solution (also called a DevOps pipeline) is the opportunity to test more frequently without burdening developers or operators with more manual work. Let's talk about why that's important.

  • Generics for Go

    The Go programming language was first released in 2009, with its 1.0 release made in March 2012. Even before the 1.0 release, some developers criticized the language as being too simplistic, partly due to its lack of user-defined generic types and functions parameterized by type. Despite this omission, Go is widely used, with an estimated 1-2 million developers worldwide. Over the years there have been several proposals to add some form of generics to the language, but the recent proposal written by core developers Ian Lance Taylor and Robert Griesemer looks likely to be included in a future version of Go. [...] Generics, also known as "parameterized types" or "parametric polymorphism", are a way to write code or build data structures that will work for any data type; the code or data structure can be instantiated to process each different data type, without having to duplicate code. They're useful when writing generalized algorithms like sorting and searching, as well as type-independent data structures like trees, thread-safe maps, and so on. For example, a developer might write a generic min() function that works on all integer and floating-point types, or create a binary tree that can associate a key type to a value type (and work with strings, integers, or user-defined types). With generics, you can write this kind of code without any duplication, and the compiler will still statically check the types.

  • Fixing a common antipattern when loading translations in Qt

    I’m a Polish guy working with computers, mostly on Windows. However, the lingua franca of the IT industry is English, so every time I see a tutorial for some dev tool, it’s in that language. To lessen the burden of decoding which menu entry in the tutorial corresponds to which menu entry on my PC I decided to run the system with an English display language. I still want the rest of the i18n-related stuff (date format, keyboard, currency etc.) to be in Polish however. [...] As you can see, Thunderbird and Windows Settings show up in English but Qt Linguist is encrypted with some overengineered Slavic cipher (aka Polish language). What I further noticed, is that this incorrect language selection is particularly prevalent in Qt-based applications. Subsequent digging revealed that this antipattern is widespread in Qt world, see the relevant GitHub search (requires login).

  • Android 10 has the fastest update rate ever, hits 16% of users in 10 months

    Google today dropped a blog post detailing its progress on improving the Android ecosystem's update speed. The company has been hard at work for the past few years modularizing Android, with the hope that making Android easier to update would result in device manufacturers pushing out updates faster. Google's efforts have been paying off, with the company announcing Android 10 has had the fastest rollout ever. The last few versions of Android have each brought a major improvement to Android's update system. Android 8 introduced Project Treble, which separated the OS from the hardware support, enabling easier porting of Android across devices. In Android 9 Pie, Google completed its work on Treble and started publishing Generic System Images (GSIs): drop-in versions of Android that work on any Project Treble-compatible device. Android 10 introduced Project Mainline and the new APEX file type designed for updatable lower-level system components, delivered through the Play Store. Google's stats show that all this work is actually improving the ecosystem. "Thanks to these efforts," Google writes, "the adoption of Android 10 has been faster than any previous versions of Android. Android 10 was running on 100 million devices 5 months post launch—28% faster than Android Pie."

Servers: Kubernetes, MicroK8s and Ubuntu

  • What’s up with the Kubernetes ecosystem

    This week’s acquisition of Rancher Labs by the veteran enterprise Linux firm SUSE neatly illustrates the growing momentum of container-based application deployment. It also underlines the importance of Kubernetes as the orchestration tool of choice for managing all those containers. So, what does this latest move mean for the broader Kubernetes ecosystem? When containers first garnered corporate attention six or seven years ago, Docker and its tools were the centre of attention. But the focus soon shifted to management frameworks capable of automating the deployment and scaling of containers, and Kubernetes, developed by Google from technology used in its cloud platform, quickly won out. Like many open source tools, Kubernetes has its share of rough edges and does not necessarily provide all the capabilities that users need to build a functioning container-based infrastructure. Companies such as Rancher sprang forth to provide a complete software stack built around Kubernetes for those who didn’t want to build it all themselves.
