=> ↺ Etnaviv DRM Driver Will Now Work On IOMMU-Enabled Systems – Phoronix

• It’s been a while since last having anything major to report on the Etnaviv Linux driver stack reporting open-source support Vivante graphics IP. With Linux 5.17 is an important step forward with the driver now behaving properly for IOMMU-enabled systems.

• While an IOMMU is important for security reasons and other purposes, the Etnaviv Direct Rendering Manager driver at present hasn’t properly dealt with the DMA configuration of the virtual device and that running into issues with an IOMMU.

=> ↺ AMD P-State v7 Driver Posted For Delivering Better Ryzen Efficiency In 2022 – Phoronix

• AMD on Christmas Eve posted their seventh iteration of the AMD P-State Linux driver as their new CPU frequency scaling solution for Zen 2+ to make use of ACPI CPPC for ultimately striving toward optimal power efficiency with a focus on mobile and desktop systems.

• This driver was developed in cooperation with Valve and has been out for review since September. Now as we end out the calendar year they are up to the seventh revision of this driver and is appearing that it may be ready for mainline soon.

• The amd-pstate driver has been evolving nicely and now working across more Zen 2 and Zen 3 systems (older processors won’t be supported due to needing ACPI Collaborative Processor Performance Controls, the CPPC support must also be enabled from the system BIOS). This driver can make more informed CPU frequency scaling decisions than the much more basic ACPI CPUFreq driver currently used by Ryzen and EPYC systems.

Instructionals/Technical

=> ↺ Make MIDI loops on Linux with this open source tool | Opensource.com

• There are many great synthesizers for Linux, and like synthesizers in real life, most of them can be controlled using the MIDI protocol. Digital audio workstations like Ardour, Qtractor, and Rosegarden can send and receive MIDI, and they have a plugin structure that permits loading most synthesizers as a component of the application. I’m a fan of modularity, though, and sometimes a big all-in-one audio workstation is more than what I need. Thanks to the combination of JACK, ALSA, and MIDI, it’s entirely possible to open a synth as a stand-alone application and use a stand-alone sequencer to play and record that synth. There aren’t many modular sequencers out there, but I use Seq24.

=> ↺ How to install Rstudio Desktop or server in Debian 11 Bullseye Linux

• R is an open-source programming language for statistical analysis and graphics whereas RStudio is an IDE for it. Here we will learn the commands to install RStudio along with R Programming language on Debian 11 Bullseye.

• With RStudio integrated development environment the user can use the GUI to start coding in the R language. This means that the IDE can only work if you have R already installed. Although the IDE can only function alongside R, the programming language can function on its own. Therefore it is not possible to replace one with the other.

=> ↺ KDE’s Bug Fixes & Other Desktop Enhancements For Christmas

=> ↺ Krita 5.0 improves resource management and includes storyboards

• Krita 5.0 You are here to continue the evolution of this popular drawing application that is also part of KDE. Without making much noise, little by little it has been making a niche in a sector that becomes demanding, and it has also done so by being published as free software.

• Krita 5.0 is a very powerful release, which is good news because it means that the project is alive and well. When it comes to what’s new, we start with the fact that the way the app handles things like brushes, gradients, palettes, and labeling has been completely revamped.

• Those responsible have explained that before they used a fragile model system to manage the resources, so Krita uses a SQLite database from this version as the nucleus to carry out this task. As a result, a large number of labeling bugs and user interface issues should have been fixed, as well as allowing faster application startup and a 200 megabyte reduction in RAM usage.

=> ↺ DIN SPEC 3105: Documenting open hardware in a standardized manner – Market Research Telecast

• When it comes to software, open source is easy to explain: the source code must be published under a free and open license, because everyone has the right to freely use the code, adapt it and distribute it. This is more difficult with hardware: In order to be able to understand, modify and reproduce hardware practically, you usually need parts lists, 3D models, circuit diagrams, circuit board layout plans and so on – depending on the technology and the targeted target group.

• [...]

• At the same time, DIN SPEC 3105 is also the first standard that was and was developed under an open license by the open source community together with the German Institute for Standardization (DIN e.V.) is free to everyone.

• Cascade is released under GPL-3.0 License.

=> ↺ Open source advent calendar: Android without Google – Market Research Telecast

• This is an advent calendar for techies. In the fully commercialized digital world, almost everything belongs to a large Internet corporation. Their software is neither open nor free. As an alternative, there is this small island of the open source world: software whose code is publicly visible and can be independently checked for possible security gaps and backdoors. Software that can be freely used, distributed and improved. Often the drive for work is simply the joy of providing something useful to society.

• Short portraits of open source projects will be published on heise online from December 1st to December 24th. These are about the functions of the respective software, the pitfalls, the history, the background and the financing. Some projects are backed by an individual, others by a loosely organized community, a tightly managed foundation with full-time employees or a consortium. The work is entirely voluntary, or it is financed through donations, cooperation with Internet companies, government funding or an open source business model. Regardless of whether it is a single application or a complex ecosystem, whether a PC program, app or operating system – the diversity of open source is overwhelming.

=> ↺ 4 conscious steps to engage people in your open source community

• Getting people involved in your open source project is important for its health and its growth, but telling people about it isn’t enough. You need to take conscious steps to increase involvement and ensure that initial contributions to a project are followed up, tying people in to the project and making them part of the community.

• If you find this post interesting, you’ll find a lot more about how community and open source are important in my book Trust in Computer Systems and the Cloud, published by Wiley.

• 1 – I’m going to be honest: I wouldn’t know where to start with TikTok. My kids will probably be appalled that I even mentioned it, but hey, why not? The chances are that you, dear reader, are younger and (almost certainly) cooler than I am.

• 2 – I’m guessing the take-up will be a bit lower here.

• 3 – In Real Life. It seems odd to be re-using this term, which had all but disappeared from what I could tell, but which seems to need to re-popularised.

Programming/Development

=> ↺ Ruby 3.1.0 Released

• We are pleased to announce the release of Ruby 3.1.0. Ruby 3.1 keeps compatibility with Ruby 3.0 and also adds many features.

• [...]

• Since Ruby 2.6 introduced MJIT in 2018, its performance greatly improved, and finally we achieved Ruby3x3 last year. But even though Optcarrot has shown impressive speedups, the JIT hasn’t benefited real world business applications.

• Recently Shopify contributed many Ruby improvements to speed up their Rails application. YJIT is an important contribution, and aims to improve the performance of Rails applications.

• Though MJIT is a method-based JIT compiler and uses an external C compiler, YJIT uses Basic Block Versioning and includes JIT compiler inside it. With Lazy Basic Block Versioning (LBBV) it first compiles the beginning of a method, and incrementally compiles the rest when the type of arguments and variables are dynamically determined. See YJIT: a basic block versioning JIT compiler for CRuby for a detailed introduction.

• With this technology, YJIT achieves both fast warmup time and performance improvements on most real-world software, up to 22% on railsbench, 39% on liquid-render.

=> ↺ Ruby 3.1 Released With Speedy, Experimental In-Process JIT Compiler

• Ruby 3.1 is out this Christmas day as a big feature release for this programming language while retaining compatibility with Ruby 3.0.

• Most exciting with Ruby 3.1 is “YJIT” as a new, experimental in-process just-in-time (JIT) Compiler. Ruby 3.1′s new JIT compiler was developed by Spotify for improving the performance of their Ruby on Rails application. YJIT should be very beneficial in improving Rails real-world application performance.

=> ↺ The 10 Best IDEs and Code Editors for Linux

• A code editor provides a text editing interface to write and edit code. It offers basic editing and formatting features to enhance the readability and management of your code. These apps usually lack advanced features and configurations.

• A notable benefit of using a code editor is that it is much lighter than an IDE. Many code editors also provide features like compiling, debugging, and support for most programming languages.

• An IDE is a software development environment that provides tools to develop complex software. It offers various tools like an editor, debugger, and compiler needed in the development cycle.

• Different IDEs provide different features and configurations suitable for specific projects. IDEs are much more advanced than editors and offer features you won’t find in a code editor.

=> ↺ Paul E. Mc Kenney: Parallel Programming: December 2021 Update

• It is past time for another release of Is Parallel Programming Hard, And, If So, What Can You Do About It?. But first, what is the difference between an edition and a release?

• The main difference is the level of validation. For example, during the several months leading up to the second edition, I read the entire book, fixing issues as I found them. So where an edition is a completed work, a release is primarily for the benefit of people who would like to see a recent snapshot of this book, but without having to install and run LaTeX and its dependencies.

=> ↺ Upgrade Node.js for your Ghost

• When upgrading Node.js, you need to run the update for Node and then also re-install Ghost’s dependencies. This is because Ghost has several binary dependencies which are compiled for the specific Node.js version. Without reinstalling dependencies, Ghost will fail to start with strange error messages.

=> ↺ Novelty Christmas Songs You Definitely Need Under Your Christmas Tree

• It’s that time of year again, folks! As the weather changes and the calendar pages start falling off rapidly, another holiday season is upon us. In 2019, we embarked on a somewhat ambitious project: The Twelve Things of Tedium. Ernie, Andrew, and I all contributed four items apiece to create a wonderful holiday project of which we’re all quite proud. The interdisciplinary yuletide extravaganza was fun, but was conspicuously absent in 2020 (we talked about The Gingerbread Man instead). With 2021 wrapping up as yet another unspeakable nightmare, we thought it might be a good time to revisit one of our favorite topics: Christmas novelty songs. So pour yourself a glass of eggnog, gather around the holiday ornamentation of your choice, and crank up the volume as we welcome you, dear readers, to the Tedium Christmas Novelty Song Spectacular.

=> ↺ Winter Session 2021: A Digital Rights Review

• The Winter session of Parliament saw frequent disruptions over the suspension of 12 members of Rajya Sabha, demanding the resignation of the Minister over the Lakhimpur Kheri incident and later the Election Laws (Amendment) Bill, 2021. In this post, we take a look at these disruptions and analyse how the Parliament fared with respect to digital rights.

• A look back

• The winter session of the Indian Parliament this year was quite extraordinary. Once again, we saw several days washed out, as the protests about the suspension of 12 Rajya Sabha members over their misconduct on the last day of the monsoon session and the Lakhimpur Kheri incident where 8 farmers lost their lives led to multiple adjournments of both the houses.

• The Winter Session saw 12 Bills, including the Farm Laws Repeal Bill, 2021 and the Election Laws (Amendment) Bill, 2021. The Farm Laws Repeal Bill, 2021 was passed on the first day itself in both Houses in less than 10 minutes without discussion. The Election Laws (Amendment) Bill, 2021 was passed within three hours of its introduction in Lok Sabha and within two hours of its introduction in Rajya Sabha. Further disruptions continued, however, with the completion of “essential government business” with the passing of the Election Laws (Amendment) Bill, 2021, the house was adjourned sine die a day ahead of schedule.
