=> ↺ Nitrux 2.2.1 Quick overview #linux #Nitrux – Invidious

=> ↺ Mint Xfce WISHES to be this good. Linux Lite 6.0 – Lightweight Linux ep. 4 – Invidious

• After many years, I try out Linux Lite 6.0 in my quest to find out what sacrifices you make when using a lightweight Linux distribution.

=> ↺ 290: 7 Linux Gadgets You Might Not Know About Plus The Great Debian Debate of 2022 – Destination Linux – TuxDigital

• This week’s episode of Destination Linux, we’re going to be talking about hardware gadgets you may have never heard about, but will have you screaming “take my money”. Then we will be discussing the great Debian debate of 2022. Plus, we have our tips/tricks and software picks. All this and more coming up right now on Destination Linux to keep those penguins marching!

Kernel Space

=> ↺ Linux Kernel 6.0 RC1 is out with Run-Time Kernel Verification

• Following the Linux Kernel 5.19 released a few days back, Linus released the first release candidate of Linux 6.0 for testing. It officially closes the merge window for this release while you test.

• Why 6.0?

• Usually, the mainline Kernel version increases by the minor version and this release should have been Kernel 5.20. However, Linus decided to increase the significant version number, hence the Kernel 6.0.

Graphics Stack

=> ↺ NVIDIA Jetpack 5.0.2 release supports Ubuntu 20.04, Jetson AGX Orin

• The NVIDIA Jetpack 5.0.2 production release is out with Ubuntu 20.04, the Jetson Linux 35.1 BSP 1 with Linux Kernel 5.10, an UEFI-based bootloader, support for Jetson AGX Orin module and developer kit, as new as updated packages such as CUDA 11.4, TensorRT 8.4.1, cuDNN 8.4.1.

• NVIDIA Jetson modules and developer kits are nice little pieces of hardware for AI workloads, but the associated NVIDIA Jetpack SDK was based on the older Ubuntu 18.04 which was not suitable for some projects. But the good news is that Ubuntu 20.04 was being worked on and initially available through the Jetpack 5.0.0/5.0.1 developer previews, and NVIDIA Jetpack 5.0.2 SDK is the first production release with support for Ubuntu 20.04.

Applications

=> ↺ Marktext is an Excellent Editor Even for Those Who Don’t Know Markdown – It’s FOSS

• Another Markdown editor? Have we not seen all kinds of Markdown editors already?

• I understand that feeling. If you are a Markdown lover, from Joplin to Zettlr, you have tried most of them. And if you are not a Markdown fan, you probably don’t care about these editors.

• Markdown is an excellent markup language specially for people who write for the web. I am not going to go into the details here. We have an excellent Markdown starters guide if you are interested in learning more about it.

• My focus here is on introducing you to (another) Markdown editor, It’s called Marktext and it is an Electron app (don’t hate me just yet).

• [...]

• I have experimented with a number of markdown editors and there are plenty of good ones there. However, I took an instant liking to Marktext and it is going to be on my system for a long time.

Instructionals/Technical

=> ↺ How to Install NVIDIA Drivers on Linux Mint 21

• Install the official Nvidia drivers if you use a Linux machine for graphics design or gaming. While most recent Linux Desktop systems have the Nouveau open-source graphics device driver for Nvidia video cards, it is not as feature-rich as the official Nvidia driver. The official Nvidia driver offers improved performance and additional functionality, making it the superior solution for demanding workloads. Installing the driver is simple, although it does need a few steps. To begin, identify your graphic card model and locate the necessary driver on the Nvidia website. After downloading the driver, you must unzip it and execute the installation. Following these instructions, you should see improved performance from your Nvidia card.

=> ↺ How to set up Packit to simplify upstream project integration

• If you use open source projects from GitHub or GitLab in your infrastructure, you have probably established workflows to create project builds that you can install. You might create builds regularly and execute them in a similar manner across projects. Let’s say you want to build the code changes in Fedora Linux or CentOS Stream for each commit, release, or pull request in these projects. Packit can automate this policy, fold into a CI/CD pipeline, and do even more.

• Packit is an open source project that tests and builds RPM packages on Fedora Linux, CentOS Stream, and other distributions to ease the integration of upstream projects with the distributions.

• This article focuses on Packit Service, which operates on GitHub and GitLab. You can also install a command line interface (CLI) locally to run Packit on your desktop or laptop.

=> ↺ Useful SSH Cheat Sheet for Linux System Administrators

• SSH or Secure Shell program is renowned for its secure operation of network services via a cryptographic network protocol. In most cases, the network interface in use has questionable security hence the need for SSH.

=> ↺ What Is a Segmentation Fault in Linux System?

• To understand the concept of a segmentation fault in a Linux operating system environment, we have to first address the concept of segmentation. In operating systems; under process management, each process is associated with a distinct virtual address space, hence the concept of segmentation.

• Supposing a memory location like 0×877 is evident on your Linux operating system. Also, suppose two processes (A and B) have access to read this memory location (0×877).

=> ↺ Calcurse – A CLI Based Calendar and Scheduling Tool Linux

• When you decide to fully dive into the Linux system ecosystem, you will soon realize that time is never fully on your side. You will want an organized time map to manage your computing objectives but find yourself failing to check some boxes just because you have not yet discovered the importance of having a calendar and scheduling tool on your Linux system.

• This article will walk us through the installation and basic usage of a CLI-based calendar and scheduling tool called Calcurse.

=> ↺ How to Install Latest Vim 9.0 in Linux Systems

• Vi has been around for a long, developed around 1976, it offered users traditional yet powerful features such as an effective editing interface, terminal control, and many more.

• However, it lacked certain captivating features for example multiple screens, syntax highlighting, multiple undo functionality, and so on, that many Unix/Linux users were looking for in a complete text editor.

=> ↺ How To Install Microsoft Edge on Linux Mint 21

=> ↺ steals passwords

=> ↺ ZFS volumes and VirtualBox | [bobulate]

• The command zfs create is used to create ZFS datasets. No surprise there. With the -V option, a volume is created rather than a regular dataset (e.g. a filesystem). So let’s create a 16GB volume on the pool called zippy (that’s a single SSD scratch drive attached to my system; the name isn’t important and your pool will probably be called something else).

• zfs create -V 16G zippy/freebsd12-test

• Now there’s a /dev/zvol/zippy/freebsd12-test character device. This can be written to. For all intents and purposes, it is a disk. The next step is to tell VirtualBox about the existence of this new disk. This is best done while VirtualBox (the UI) isn’t running.

=> ↺ How To Fix “Rmdir: Directory Not Empty” Error In Linux

• The rmdir command is used to remove empty directories. If you attempt to remove a non-empty directory with this command, you’ll encounter the Rmdir Directory Not Empty error.

• That much is intended behavior, but some users have reported cases where they faced this error despite using rmdir on an empty directory. This happens due to reasons like file system errors or broken symbolic links.

=> ↺ The simplicity and complexity of using quotes on Linux | Network World

• There are only a few special characters involved in working with character strings on the command line or in a script on Linux: the single quote, the double quote and the backslash. But the rules aren’t as obvious as one might think. In this post, we’ll look at the easy and the somewhat tricky uses of these special characters.

=> ↺ Using the watch command on Linux | Network World

• The watch command allows you to rerun commands in a loop until you stop it or run into a condition that stops the looping for you. It can be very useful when you’re waiting for something to change before you can move on to the next task.

=> ↺ Check Disk Space Using Agedu In Linux – OSTechNix

• Running out of disk space? It is time to find out which directories and files are occupying the most disk space. Fortunately, checking Linux disk space is made easier with Agedu utility. This guide explains what is Agedu, how to install Agedu, and how to check disk space in Linux and find wasted disk space using Agedu.

Games

=> ↺ Status update, August 2022

• It is a blessedly cool morning here in Amsterdam. I was busy moving house earlier this month, so this update is a bit quieter than most.

• For a fun off-beat project this month, I started working on a GameBoy emulator written in Hare. No promises on when it will be functional or how much I plan on working on it – just doing it for fun. In more serious Hare news, I have implemented Thread-Local Storage (TLS) for qbe, our compiler backend. Hare’s standard library does not support multi-threading, but I needed this for Helios, whose driver library does support threads. It will also presumably be of use for cproc once it lands upstream.

=> ↺ Adventure game graphics with DALL-E 2 – Et tu, Cthulhu

• I recently got access to OpenAI’s DALL-E 2 instance. It’s a lot of fun, but beyond its obvious application as a cornucopia of funny cat avatars, I think it’s now fit to use in certain kinds of creative work.

• There are already plenty of good articles out there on the model’s strengths and weaknesses, so I won’t go over that here other than to note that it’s not a threat to high art. It’s got an idea of what things look like and how they can visually fit together, but it’s very vague on how they work (e.g. anatomy, architecture, the finer points of Victorian-era dinner etiquette, art critics), and object inpainting aside, it doesn’t rise to the level of realism where I’d worry too much about the fake news potential either.

• However, with human guidance and a carefully chosen domain, it can still do some very impressive things. I’ve suspected that adventure game graphics in the point-and-click vein could be one of those domains, and since I’m helping someone dear to me realize such a game, I had the excuse I needed to explore it a little and write this case study.

=> ↺ Enthusiast Creates Arm64 Linux Kernel Capable of Running Nintendo Switch Games

=> ↺ New Linux Build Runs Nintendo Switch Games on Arm64 Devices

• A Linux OS and Nintendo Switch enthusiast has mind-melded the two disparate systems to create Horizon Linux. In brief, a Redditor by the name of Kent J Hall has patched the Arm64 Linux kernel to run Nintendo Switch games natively. Hall stresses this isn’t an attempt to recreate Nintendo’s Horizon OS, and it isn’t meant to run on Switch hardware – rather the project simply hopes to make Switch games on any Arm64 hardware platform.

• After a false start or two, Hall decided to spend a chunk of his free time on the Horizon Linux project summarized above. Patching Arm64 Linux seemed the sensible route to reach his goal as it meant “you get Linux’s vast hardware driver support for free, so not only can it be virtualized on Apple silicon Macs, but it can run bare-metal on any arm64 hardware which supports Linux,” explained Hall. The project should work fine “even on lower-end hardware, given that there’s no need to emulate the CPU,” he added. Moreover the project is flexible, and holds promise for game preservation.

Distributions and Operating Systems

=> ↺ Top 10 popular Linux distros in August 2022 – Linux Shout

• Let’s check out the list of the most popular Linux distros in August 2022, in case you are planning to switch to Linux OS.

• Unlike Windows and macOS, Linux is not just owned by some single brand instead it is free & open source and even offers multiple choices. Yes, of course, the Linux kernel is the thing that is common in all distros, so what makes them different? It is – features, ease of usage, updates, security, lightweight, packages, and interface. Although among regular Desktop users, Linux is not in majority, however, if we talk about servers then most of them are powered by Linux OS such as RedHat, Ubuntu, Debian, OpenSUSE, and others. Therefore, whether you are a student, administrator, developer, or just a common user who likes to explore Linux distros, here is the list of some most downloaded and popular Linux distros of August month in 2022.

• [...]

• The given arrangement of Linux distros is not feature-wise instead the number of times they have been downloaded in the month of August 2022.

Red Hat / IBM

=> ↺ How to deploy MicroShift on your laptop quickly | Enable Sysadmin

• In previous articles, I explained how to generate a Red Hat Enterprise Linux 9 image with MicroShift. I relied on AWS services and a somewhat complicated process for those articles.

• MicroShift is a project exploring how to optimize OpenShift (Red Hat’s Kubernetes) for small form factor and edge computing. MicroShift’s goal is to tailor OpenShift for field-deployed device use cases, providing a consistent development and management experience across all footprints.

=> ↺ Connect MongoDB to a Node.js application with kube-service-bindings | Red Hat Developer

• This is the third and final article in a three-part series introducing kube-service-bindings for Node.js developers on Kubernetes. Together with the Service Binding Operator (SBO), kube-service-bindings makes it easier to share credentials for services with your applications.

• The first article of this series offered background on the tools we’re using, and the second set up some basic elements such as hosting on the Developer Sandbox for Red Hat OpenShift and a MongoDB database. Now we’re going to use all these tools to create a binding between our Node.js application and the database.

=> ↺ Enable backing services in Kubernetes with kube-service-bindings | Red Hat Developer

• This is the second part of a three-part series explaining how to bind easily to databases and other backing services from Node.js applications running in Kubernetes. The first article in the series, Connect to services on Kubernetes easily with kube-service-bindings, introduced the tools we use for this simplified integration: kube-service-bindings and the Service Binding Operator (SBO).

• In this article and the next, we’ll set up a cluster with access to a MongoDB database. For our Kubernetes cluster, we use the Developer Sandbox for Red Hat OpenShift, a free service for developers to experiment and learn about open source tools.

• The articles use a MongoDB example hosted in GitHub to show you kube-service-bindings in action. This example will illustrate the process of deploying a Node.js and MongoDB application in OpenShift. The final step is to establish a connection between the processes with the Service Binding Operator and kube-service-bindings.

=> ↺ IT leadership: Why adaptability matters

• Even Daniel Goleman – author of Emotional Intelligence: Why It Can Matter More Than IQ – may not have anticipated the heightened role that emotional intelligence (EQ) plays in today’s workplace. EQ is now considered an essential leadership skill, the cornerstone of many management and leadership development programs.

• Understanding EQ creates a foundation for exploring other aspects of human behavior. Decision-making, stress management, positivity, risk tolerance, and psychological safety are based on emotional intelligence.

Debian Family

=> ↺ Debian turns 29!

• Today is Debian’s 29th anniversary. We recently wrote about some ideas to celebrate the DebianDay, and several events have been planned in more than 14 locations. You can join the party or organise something yourselves too!

• Today is also an opportunity for you to start or resume your contributions to Debian. For example, you can have a look at our list of Debian Teams, install the how-can-i-help package and see if there is a bug in any of the software that you use that you can help to fix, start designing your artwork candidate for the next release, contribute small tips on how to install Debian on your machines to our wiki pages https://wiki.debian.org/InstallingDebianOn/, or put a Debian live image in an USB memory and give it to some person near you, who still didn’t discover Debian.

=> ↺ Volunteers were punished for Debian Day suicide disclosures

• In 2016, when people attacked Dr Appelbaum with a gossip campaign, the Debian leader had few reservations making a public statement against Dr Appelbaum’s human rights.

• The allegations against Dr Appelbaum were nothing more than a social media mob. The suicide of Frans Pop was very real, with a body and a note to prove it. The Debian Social Contract tells us we will not hide problems. Therefore, why was this body hidden for twelve years?

• Suicides are a matter of public record. A coroner conducts an inquest in open court. The suicide was closely intertwined with Debian culture. Hiding the suicide was closely intertwined with hiding Debian’s real face. Yet doing that is a slap in the face of the social contract.

• If Frans Pop had only become engaged with Debian a few weeks before his death and if he had some previous health issues then it would be correct to avoid public comment on that. But as he was working on a core part of the operating system, the Debian installer, he had been actively engaged with Debian for many years, he aligned the suicide with Debian Day and he communicated with us immediately before his death, it is unambiguous that Debian was a factor. It raises concern for the wellbeing of all volunteers. In a voluntary organization committed to transparency, this is exactly the type of risk that belongs in public.

• Here is the email where German developer Joerg Jaspert takes his stick to the volunteers who expressed concern about the suicide in public. Joerg’s assertion that discussion is “missing every kind of common sense and decency” is nonsense. Common sense means different things for different people. For most volunteers, common sense would suggest doing all that is possible to avoid another suicide. For people in positions of authority over other volunteers, common sense means covering it up.

Devices/Embedded

=> ↺ myBuddy 280 dual arm robot features Raspberry Pi 4 SBC and ESP32 controllers

• Elephants Robotics myBuddy 280, aka myBuddy 280 Pi, is a dual-arm collaborative robot for education with a 7-inch display powered by Raspberry Pi 4 SBC, and also features three ESP32-based M5Stack core modules that help with the internal communication between the motors and the Raspberry Pi board.

• It builds upon the earlier myCobot 280 Pi robot with a single arm, with the same 280mm working range, but the new robot offers two arms, and a total of 13 degrees of freedom (DoF). The robot is also equipped with two 2MP HD cameras for computer vision, a standard 3.3V expansion I/O interface, a LEGO expansion interface, and can be fitted with a variety of adapters such as suction pumps, grippers, little hands (see below), etc…

Programming/Development

=> ↺ 7 Top Free and Open Source Clojure Web Frameworks

• A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.

• Clojure is a dialect of the Lisp programming language. It’s a well-rounded language. It offers broad library support and runs on multiple operating systems.

• When it comes to web development, there are many Clojure frameworks to choose. The choice depends on finding the right tool for the job at hand. Here’s our pick of the finest Clojure web frameworks.

=> ↺ Type support: working with sudo logs in syslog-ng 4.0 – Blog – syslog-ng Community – syslog-ng Community

• Last week I gave you a quick introduction to a major syslog-ng 4.0 feature: type support. I mentioned that it also works nicely for JSON-formatted sudo logs. I have been asked to share a working syslog-ng configuration.

• From this blog, you can learn how to turn on JSON-formatted logging in sudo, and how to work with those logs in syslog-ng.

=> ↺ Sam Thursfield: Status update, 16/08/2022

• For the first time this year I got to spend a little paid time on open source work, in this case putting some icing on the delicious and nourishing cake that we call BuildStream 2.

• If you’ve tried the 1.9x pre-releases you’ll have seen it depends on a set of C++ tools under the name BuildBox. Some hot codepaths that were part of the Python core are now outsourced to helper tools, specifically data storage (buildbox-casd, buildbox-fuse) and container creation (buildbox-run-bubblewrap). These tools implement remote-apis standards and are useful to other build tools, the only catch is that they are not yet widely available in distros, and neither are the BuildStream 2 prereleases.

• Separately, BuildStream 2 has some other hot codepaths written with Cython. If you’ve ever tried to install a Python package from PyPI and wondered why a package manager is running GCC, the answer is usually that it’s installing a source package and has to build some Cython code with your system’s C compiler.

• The way to avoid requiring GCC in this case is to ship prebuilt binary packages known as wheels. So that’s what we implemented for BuildStream 2 – and as a bonus, we can bundle prebuilt BuildBox binaries into these packages. The wheels have a platform compatibility tag of “manylinux_2_28.x86_64” so they should work on any x86_64 host with GLIBC 2.28 or later.

=> ↺ The curl release cycle | daniel.haxx.se

• In the curl project we do timed releases and we try to do them planned and scheduled long in advance. The dates are planned. The content is not.

• I have been the release manager for every single curl release done. 209 releases at current count. Having this role means I make sure things are in decent shape for releases and I do the actual mechanic act of running the release scripts etc on the release days.

• Since 2014, we make releases on Wednesdays, every eight weeks. We sometimes adjust the date slightly because of personal events (meaning: if I have a vacation when the release is about to happen, we can move it), and we have done several patch releases within a shorter time when the previous release proved to have a serious enough problem to warrant an out-of-schedule release. Even more specifically, I make the releases available at or around 8 am (central euro time) on the release days.

• The main objective is to stick to the 56 day interval.

• It probably goes without saying but let me be clear: curl is a software project that quite evidently will never be done or complete. It will keep getting fixes, improvements and features for as long as it lives, and as long as it lives we keep making new releases.

Rust

=> ↺ Contribute to the diagnostic translation effort!

• The Rust Diagnostics working group is leading an effort to add support for internationalization of error messages in the compiler, allowing the compiler to produce output in languages other than English.

=> ↺ Microsoft finally admits Xbox One sales were less than half of the PS4

• Official Xbox One sales have largely been a mystery, but now Microsoft is finally admitting the obvious: the PS4 outsold the Xbox One — by a lot. Microsoft stopped reporting its Xbox One sales figures at the beginning of its 2016 financial year, focusing instead on Xbox Live numbers. The change meant we’ve never officially known how well Xbox One was holding up compared to the PS4 after the Xbox One’s troubled launch.

=> ↺ The grass is not always greener

• Let me preface this post by saying that I still do prefer my new job to my old one. That being said, it ain’t perfect. It’s a good reminder to not imagine things better than they are, then act as if those imaginations are reality.

• Ekzemple: At my old job, a mailing of 170-200 mailpieces was a hassle that took an hour or two. At my new job, it took eight hours (разъяснение: I’m new and the printers are slow.)

Technical

=> ↺ Evaluating our relationship with technology

• We should keep invasive proprietary technologies at bay by limiting our reliance on them. Further more, we should assess in what ways technology, in general, has affected our lives, by compromising our relationships and daily doings. I am not a tech-luddite by any means, technology is one of my hobbies, specifically system administration of Unix-like operating systems, but, as an individual, then as a collective, we can all feel something is off.

=> ↺ Back to VM again

• I’m back to using a tiling vm again. I’ve used KDE Plasma for quite a while, but after browsing r/unixporn for a bit too much I could no longer contain the desire for ricing. So I logged back into my i3-gaps vm and got to work. Well, it wasn’t exactly i3, it was actually both Plasma and i3. I had previously changed KDE’s vm from kwin to i3, and had both Plasma and Plasma with i3. And let me tell you, Plasma with i3 is the perfect combination of DE and VM. You get the convenience of a DE with the speed of a VM. It’s sooo sweet.
