=> ↺ System76 Linux workstation looks ready for gaming, too | Ars Technica

• System76′s latest Linux laptop combines one of AMD’s most powerful 5000 series mobile CPUs with Nvidia’s mid-range RTX 3060. Configurable to up to $3,442, the Kudu targets Linux users who have a lot of work to do, while quietly nodding at those who like to play games every now and then, too.

• The 15.6-inch Kudu is the second-priciest offering in System76′s laptop lineup. It comes with an octa-core AMD Ryzen 9 5900HX, which has a base clock speed of 3.3 GHz and a boost of up to 4.6 GHz.

• [...]

• However, you can find cheaper Windows-based gaming laptops with similar power. And at its base configuration, the Kudu has 8GB of memory and just 240GB of storage but is still a pricey $1,800.

• Connectivity may disappoint, as there’s no Thunderbolt 4, like in System76′s Oryx Pro. Instead, the Kudu comes with USB 3.2 Gen 2 Type-C and A, USB 3.2 Gen 1 Type-A, USB 2.0 Type-A, Mini DisplayPort 1.4, HDMI, and two audio jacks. There’s also Ethernet, Wi-Fi 6, and Bluetooth 5.

=> ↺ Delays hold back AMD HIP Linux GPU Acceleration for Blender 3.2 release

• Blender 3.0 introduced AMD HIP acceleration to the Cycles X render coding due to the removal of OpenCL. The support from AMD for Blender was restricted to Windows systems only, with probably Linux support added for Blender 3.1. However, AMD’s delay on drivers means that the HIP Linux support is now anticipating a launch with Blender 3.2. Blender 3.1 will launch in March 2022.

=> ↺ ACPI Platform Profile support for Lenovo AMD-based systems on Linux is broken

• ACPI Platform Profile support on Linux allows users to balance power or performance choices with modern laptops on the Linux platform. In general, it has worked without error across several devices experimented but is now malfunctioning with AMD Ryzen powered Lenovo systems.

• ACPI Platform Profile support permits users to select the power, balance, and power-savings preferences, along with other potential profiles, on Linux with current kernel activity that witnesses direct support obtainable for leading laptop brands such as Lenovo, Dell, and ASUS, to name a few. The consumer’s profile preference is controlled from inside a sysfs interface. Desktops like KDE Plasma and GNOME have already added suitable user interfaces to arrange it adequately from the system settings location.

=> ↺ Build your own container on Linux | Opensource.com

• Containers are run in the cloud. That’s because container technology allows websites and web apps to spawn fresh copies of themselves as demand increases. They’re the reason hundreds of millions of people can use popular sites without those sites buckling under the pressure of global traffic. Containers are a Linux technology, meaning that they rely on code (specifically cgroups and namespaces) unique to the Linux kernel, so when you run a container, you’re running Linux. Using container images from sites like quay.io and dockerhub.io, most people build new containers specific to their application or use case. But that makes some people wonder: If my container comes from a developer building on top of another developer’s container, where do those containers come from? Don’t worry, it’s not turtles all the way down. You can build a container from scratch, and there’s a great open source tool called Buildah to help you do it.

=> ↺ How to Change the Lockscreen Wallpaper on Ubuntu

• At one point or another, if you’ve ever worked with computers, you’ve wanted to personalize your computer to reflect your likes, dislikes or hobbies. While the customization options on Windows leave little to the imagination, there aren’t many options with Ubuntu 20.04 right out of the box. If you want to go beyond the default tools, you have a plethora of customization applications that can transform the look and feel of your desktop into something completely new.

• In Ubuntu desktop settings, you can change your desktop wallpaper and move the icons around, but not much more. So, what about the lock screen? There are no built-in options to customize that. If you want to update the wallpaper on the lock screen of your Ubuntu 20.04, I will guide you on how to do that.

=> ↺ Using GeckoLinux to resurrect my old nettop | Fitzcarraldo’s Blog

• In 2010 so-called smart TVs were not really that smart. I still had a large Sony Trinitron TV with a CRT, and I wanted to see if I could use the nettop with it. I bought a DVB-T USB adapter to enable the nettop to access digital terrestrial television, and I installed XBMC (now called KODI). I installed the now-defunct Sabayon Linux, and had a hell of a job getting ASRock’s CIR [Windows] MCE (Media Center Edition) remote to work. ASRock only released a driver (lirc_wb677) for the Nuvoton w836x7hg CIR chip in the nettop for Ubuntu 9.10, 10.04 and 10.10, and I had to patch it to get it to work with LIRC in Sabayon Linux. Later that year developer Jarrod Wilson released the first version of a new driver named nuvoton-cir for the Nuvoton w836x7hg chip, and in 2011 I had another struggle to get that working with LIRC and XBMC in Sabayon Linux. To be able to use the DVB-T USB adapter I installed Tvheadend in Sabayon Linux, which worked well, although the adapter needed to be connected to the house TV aerial in order to provide good reception, i.e. the small indoor aerial supplied with the DVB-T adapter was next to useless. I bought a VGA-to-Composite Video converter to connect the nettop’s D-Sub VGA socket to the TV’s composite video input. The Linux Desktop displayed on the CRT TV screen was OK-ish but, as you would expect, not comparable to the display on a TFT monitor. Basically, I was not satisfied with the result, and the nettop went back into its box after very little use. I did get it out briefly in 2016 to upgrade the 2GB RAM (two 1GB modules) to the maximum allowable 4GB (two 2GB modules) in case I might want to use the nettop in future. With two 2GB RAM modules the nettop detects 3327MB of RAM, which limits what can be done with it. When ‘proper’ smart TVs came onto the market, there was no longer any incentive to use an HTPC; everything and more that a nettop HTPC did could be done by a smart TV. In 2015 I succumbed and bought an LG smart TV, added a USB 1TB HDD, connected my DVD player to the TV and forgot about the nettop. The LG TV developed a fault three years later. I fixed it but its lack of catch-up TV apps for some of the main TV stations became irritating so, three years ago, I bought a new TV. The media player on the TV (a FINLUX TV) cannot play FLAC music files, and the Web browser is very slow with a buggy UI, so I began thinking about resurrecting the ASRock nettop in order to be able to browse the Web properly on my TV and to play my music flles through the TV’s sound bar. I finally got around to doing this recently, so here is the story…

=> ↺ How to Manually Mount/UnMount a USB Device on Ubuntu 20.04 and 22.04 – VITUX

• When you connect a USB drive to our system, it is usually mounted automatically and a directory with your user name is created under the media folder.

=> ↺ How to Play Your Music Collection From the Linux Command Line

• Even in these days of cloud-based streaming music platforms like Amazon Music and Spotify, the chances are you’ll still want to play something from your local collection of audio files from time to time. Perhaps you have something so obscure the streaming services don’t have it. Or you ask for a particular track and they keep playing you the live version, or the extended remix, or any of the other variations when all you really want is the plain old as-first-released album track.

• Of course, Linux is well served with music players. Rhythmbox, Clementine, and Strawberry are fully-featured, sophisticated, and polished applications for managing your music collections. As well as playing your music they’ll do things like search for and download missing album art, play podcasts and internet radio, and edit the meta-data in the files themselves.

• But what if you want to access your music collection from a terminal window, without the overhead of a fully-loaded music player? Music on Console, or MOC, is a program that allows you to do just that. It loads in the blink of an eye, lets you search your music collection, find what you want to play, and just play it.

That article tried to provide a single full reference implementation of an OpenAPI-compliant REST API using Quarkus. Since then, there’s been a major version release of Quarkus, with new features that make building and maintaining a Quarkus-based REST API much easier. In this article, you will revisit the Customer API from the previous article and see how it can be improved thanks to advances in Quarkus.

• In creating this article, we made an effort to remain aware of a subtle consideration in any development effort: you always need to keep an eye on your imports. Whenever you add imports, you should consciously attempt to limit your exposure to third-party libraries, focusing on staying in the abstraction layers such as the MicroProfile abstractions. Remember, every library you import is your responsibility to care for and update.

Canonical/Ubuntu Family

=> ↺ Ubuntu vs. elementary OS: Which Is the Right Linux Distro for You?

• When one thinks about open-source desktop OSes, the buck stops at Linux. The Linux kernel has spawned numerous use case-specific distros; Ubuntu and elementary OS continue to be some of the best options available in the Linux universe.

• While both distros continue to command respect, nonetheless, they continue to battle it out on the battlefield. Both distros have unique points of mention, which make them stand out in their respective categories.

• Here’s a comparison between Ubuntu and elementary OS to make your decision simpler.

=> ↺ Ubuntu 22.04 Dailies Show an Ubuntu Pro Notification on Login – OMG! Ubuntu!

• When I wrote about the new “Ubuntu Pro” section in Ubuntu 22.04‘s software settings panel I said the banner wasn’t a nag screen or a desktop notification but something you had to go out of your way to see.

• Not so in the latest daily builds of the Jammy Jellyfish.

• Upon login today I was greeted by a desktop notification asking if I ‘want to enable Ubuntu Pro?’.

• Two actions are available when click on the notification: “Don’t remind me again” and “Enable Ubuntu Pro” (though thanks to a bug the notification will appear on every login even if you click “don’t remind me” – but that will get fixed soon).

=> ↺ Ubuntu 22.04 May Offer a Choice of System Accent Colour – OMG! Ubuntu!

• [Kevin Lynagh] is interested in tiny PCB stepper motors, and after reviewing the various projects and patents to-date, decided to give it a try himself. These are basically a stepper motor that’s been unrolled and made flat — traces on the PCB act as the coils and tiny magnetic “robots” act as the rotor.

=> ↺ Arduino Activated Automotive Aerodynamic Apparatus is… (Spoiler Alert!)

• Sometimes a great hack is great for no other reason than that it’s fun, and [Michael Rechtin]’s DIY Active Aero Spoiler and Air Brake certainly qualifies as a fun hack. This is a mod designed to live in a world where looks are everything, stickers add horsepower, and a good sound system is more important than good wheel alignment. Why is that? Because like the switch that exists only to activate the mechanism that turns it off, the DIY Active Aero Spoiler and Air Brake seen below is almost completely useless. So to understand its allure, we must understand its inspiration.

Free, Libre, and Open Source Software

=> ↺ So… How do you get started with open source contributions?

• Hey! In this post I’ve shared my personal experience with contributing to open source projects. I’m still a learner, and probably will be one for rest of my life. But I believe I’m beyond that point where I was confused about “how do I even start”. I’m recording my experience in hope that it proves to be useful to someone else.

• Since this post is meant to record my personal experience and observations, I have glossed over some commonly known practices like looking for good first issues, or learning basics of the toolchain you’ll be using. I find those advice to be abundantly available on the internet.

• [...]

• By now, you probably have some idea about how to go about making your initial contributions to your favorite project.

• Once you make your first successful contribution, you feel lot more confident. You feel motivated to take on bigger tasks, and become active in discussions. You should have already realized that this is a team effort. You work with constant back and forth reviews and suggestions. The more you participate, the more you learn. Probably for this reason, I like joining different channels and stalking their discussions. (even if I don’t understand half the technical terms they use!)

• This was a beginner sharing his experience for other beginners. Hoping this post cleared up your doubts and you feel more confident about stepping into the world of open source software development!

=> ↺ OpenStack-to-the-edge darling StarlingX hits 6.0 • The Register

• StarlingX, an open-source platform for edge computing based on OpenStack, has hit release 6.0 with a Linux Kernel upgrade plus security and deployment enhancements to make it easier to manage systems.

• The StarlingX project offers a complete software stack for edge and IoT deployments, with support for code running in containers or virtual machines. It was started by Intel and Wind River, but is now an independent project supported by the Open Infrastructure Foundation, with code available under the Apache 2 licence.

• Companies using StarlingX in production systems include T-Systems, Verizon and Vodafone, with the code freely available to download from the StarlingX website.

• [...]

• StarlingX is described as being suitable for a wide range of edge use cases and applications from telecoms through retail to industrial IoT. It supports ultra-low latency, extremely high service uptime, and small-footprint deployments.

• The Open Infrastructure Foundation’s Ildiko Vancsa, who is senior manager for its Community & Ecosystem division, said of the release: “StarlingX is already delivering the essential functionality to build out infrastructure from the core to the edge by providing a robust, flexible and scalable foundation with OpenStack that can be used to build your central cloud as well as get installed on the edge to manage a smaller pool of resources.”

=> ↺ Onehouse emerges with managed Apache Hudi data lake service

• One of the original creators of the Hudi project at Uber has launched a new company that is set to bring a managed service to market to operationalize cloud data lakes.

• [...]

• Vinoth Chandar: We built Hudi during the hyper-growth stage at Uber as a way for the company to scale its data lake and bring in data transactions faster. We made Hudi feel more like a data warehouse than just a data lake. Over the last four years, the Hudi community has grown and has helped to pioneer new transactional data lake capabilities.

• What we routinely see in the community is that it still takes a lot of time for companies to operationalize their data lakes. We felt like we can actually create value here by creating a managed service that can help you get started.

• Onehouse is not about being an enterprise Hudi company, it’s more about helping companies to get started with data lakes, with open data formats, without the need that Uber had to make to get Hudi started.

• Following the experts’ recommendation last year, we’re logically separating the two elections more clearly, although we currently don’t have the capacity to run elections at separate times. We’ll consider that option again in the future.

Web Browsers

Mozilla

=> ↺ Update on Firefox Reality

• Mozilla’s mission is to make sure the Internet remains open and accessible to all. Four years ago, we launched Firefox Reality, a browser for mixed reality, and our exploration in browsing in new and emerging realities. We’ve been at the forefront of developing new technologies, like WebVR and WebAR, and in some instances, Mozilla continues to remain the host and incubator of those new technologies, as with Hubs. With other technologies, we find communities and organizations where our projects can continue to grow and contribute to the web like WebAssembly, Rust and Servo. Today, we’re delighted to announce that the Firefox Reality browser technology will continue under Igalia where they will uphold the same principles we started when we created Firefox Reality — an open source browser that respects your privacy.

Productivity Software/LibreOffice/Calligra

=> ↺ Breath of fresh air: v7.3 of LibreOffice boasts improved file importing and rendering

• Six months after LibreOffice 7.2, version 7.3 is out with faster and more accurate file importing and rendering for improved compatibility with Microsoft Office.

• The new release is the latest “fresh” version. The Document Foundation also offers a “still” edition, which is based on an older but more extensively tested release; it’s currently on version 7.1.8. The differences aren’t that dramatic – without rehashing the release notes, these are point releases, so don’t expect huge changes.

• It has better support for importing Microsoft Office documents, and lots of relatively modest improvements in diagrams, charts, hyperlink support, and more. If you really push Microsoft’s offering hard, LibreOffice probably isn’t for you, but if like most of us you barely scratch the surface of what it can do, you will probably be fine with LibreOffice.

• Yes, we’re here.

• After literally years of awfulness, I’ve finally solved (for good) the debacle that is point size conversion from GL to Vulkan.

• What’s so awful about it, you might be asking. How hard can it be to just add gl_PointSize to a shader, you follow up with as you push your glasses higher up your nose.

• Allow me to explain.

=> ↺ Suntime Calculation with Lua and the Great Gift of Open Source

• Sometimes there are those unremarkable things which let you pause for a moment, and realize what a great gift of our time open source software and open knowledge is. At some point in time someone figured out how to calculate the sunrise and sunset time on the current date for your location. Someone else wrote that up and probably again a different person published it on the internet. The Internet Archive preserved a copy of it so I can still link to it. Someone took this algorithm and published a code sample on StackOverflow, which was later on used by the SatAgro guys to create the python-suntime library. Now I could come along, copy the core function of this library, and convert it within a few hours, mostly spent learning a few things about Lua, to a Lua script.

=> ↺ 5 Excellent Free Books to Learn Crystal – LinuxLinks

• Crystal is a general-purpose, concurrent, multi-paradigm, object-oriented programming language.

• With syntax heavily inspired by the language Ruby, it is a compiled language with built-in static type-checking, but specifying the types of variables or method arguments is generally unneeded. This adds the benefit of a shallower learning curve.

• The language also offers a powerful macro system, the compiler automatically checks for null references in compile time, a sleek concurrency model that uses green threads, as well as dedicated syntax to easily call native libraries.

• Crystal is published under the Apache License 2.0.

• The Linux expand and unexpand commands sound like they can make files larger and smaller, but what they actually do is turn tabs into spaces and spaces into tabs.

• In this post, we’ll use some simple text files to demonstrate what happens when you use expand and unexpand. We’ll also compare how these commands work with some likely more familiar commands—sed and awk—that can provide similar results and offer additional options.

Rust

=> ↺ Async Rust in 2022

• Almost a year ago, the Async Working Group embarked on a collaborative effort to write a shared async vision document. As we enter 2022, we wanted to give an update on the results from that process along with the progress we are making towards realizing that vision.

• [...]

• To set the scene, imagine it’s Rust 2024, and you’ve decided to build your first project in Rust. You’re working on a project that uses GitHub and you’d like a tool that will walk over all the issues on your repository and do some automatic triage. You decide to use async Rust for this. You pull out the Rust book and thumb over to the Async I/O section. In there, it shows you the basic structure of an async Rust application.

Science

=> ↺ Shining A Different Light On Reality With Short-Wave Infrared Radiation | Hackaday

• As great as cameras that operate in the visual light spectrum are, they omit a lot of the information that can be gleaned from other wavelengths. There is also the minor issue that visibility is often impacted, such as when it’s raining, or foggy. When this happens, applications such as self-driving cars which rely on this, have a major issue. Through the use of sensors that are sensitive to other wavelengths, we can however avoid many of these issues.

• Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves, and above long-wave IR at 20 THz – 37 THz. LWIR is what thermal cameras use, with LWIR also emitted by warm objects, such as the human body.

• SWIR is largely unaffected by water in the atmosphere, while also passing through materials that are opaque to visible light. This allowing SWIR to be used for the analysis and inspection of everything from PCBs and fruit to works of art to capture details that are otherwise invisible or very hard to see.

• Unfortunately, much like thermal camera sensors, SWIR sensors are rather expensive. Or they were, until quite recently, with the emergence of quantum-dot-based sensors that significantly decrease the costs of these sensors.

=> ↺ 3D Printed Circular Prototype Performance Prop Captivates Circus Spectators | Hackaday

• When mathematically inspired maker [Henry Segerman] conspired with circus performer and acrobat [Marcus Paoletti] to advance the craft of acrobatics in round metal objects (such as cyr wheels and German Wheels), they came up with a fascinating concept that has taken shape in what [Henry] calls the Tao-Line.

• Similar performance devices go in a straight line or can be turned on edge, but the Tao-Line is far more nimble. This is because the Tao-Line is not a continuous cylinder, but rather is made up of numerous circular shapes that allow the Tao-Line to be turned and inverted at different points in its rotation.

=> ↺ Software Defined Storage: Does the model still work? – Random [Tech] Stuff

• What does that mean though? What is Software Defined Storage (often abbreviated to SDS)? At a high level: It is independent software used to manage storage hardware, regardless of the type or hardware vendor. The idea is a simple one. Most off-the-shelf hardware has been somewhat commoditized. That is, take your HP’s, your Dell’s, Supermicro’s or anything else. Fill it with whatever Seagate, Western Digital, HGST, and / or other storage drive. Then let the software do its magic. Under this model, it is the software that has become the defining factor.

• It is an attractive approach to managing your data. Think about it: no hardware vendor lock-in. Instead of being an EMC shop or a NetApp shop, you are now given the option to mix and match hardware while relying on the software to bring it all together.

• Although, there is a downside to all of this. Let us ignore the obvious fact that it is up to you to locate and purchase the hardware separate from the software. Software Defined Storage promises us the world but only in recent years has started to showcase its shortcoming: that being centered around the hardware.

• One big obstacle on the path towards an all-electric car future (besides pipe-dreams like these, of course!) is that it is hard to build enough economically sustainable charging stations, if there is no standardization to speak of behind those chargers. That’s why it is great that the Linux Foundation (LF) just announced plans to fix this lack of standardization with a new project called “LF Energy EVerest”.

=> ↺ Algorithmic decision-making in the U.S. needs accountability

• Today, U.S. Senators Ron Wyden, Cory Booker, and Representative Yvette Clarke introduced the Algorithmic Accountability Act of 2022 — a bill that holds the tech industry responsible for the life-altering judgements their automated decision systems make. Access Now is proud to endorse this legislation, which would help combat the devastating impacts companies’ algorithmic systems have on the welfare of people who rely on digital platforms — from approving loans, to issuing medical prescriptions.

• “Opaque and often-biased algorithms are deciding who has access to housing, education, and other opportunities, and we should be concerned,” said Willmary Escoto, U.S. Policy Analyst at Access Now. “The tech firms who deploy these automated decision systems usually answer to no one. By requiring companies to assess the impacts of the systems they use and sell, this bill will help combat algorithmic discrimination in defense of human rights.”
