Slackware 15 has [still] been released, and in this episode, thanks to feedback from Hackerdefo and Blackernel, Klaatu lists all the ways you can install it.
How discord is still missing an overlay on Linux after all these years baffles me but luckily the open source community saves the day and after a few rewrites we now have an incredibly good discord overlay with as much tweaking as you could want.
One of the most common questions that I get from programmers and developers who are discovering the free and open source movements is: "Is it possible for me to make money selling open source?" Can a developer actually earn a living if there code has to be open source and publicly available?
Last month, the Linux kernel turned 30. If you’re someone who’s been immersed in the Linux world since Y2K like me, it may feel a bit surreal that so much time has passed since the kernel’s inception.
As a training architect at A Cloud Guru (ACG), I teach courses about all things Linux and specialize in hands-on, lab-based learning. Before joining ACG, I worked as a Unix systems engineer at GE and IBM as well as Technical Account Manager and customer advocate for Red Hat. I’m hugely passionate about Linux because of its importance to my career, just like to the careers of so many other engineers and Linux enthusiasts.

Let’s get cracking with the best free, open-source video converters for Linux.
An interactive whiteboard is an instructional tool consisting of a large interactive display in the form factor of a whiteboard. The whiteboard can be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector.
The instructor can manipulate the elements on the board by using his finger as a mouse, directly on the screen. Items can be dragged, clicked and copied and the instructor can make handwritten notes, which can be transformed into text and saved.
The hardware is used in many environments, including classrooms at all levels of education. Interactive whiteboards let teachers draw on the screen from the front of the room and save their lessons. They offer the opportunity to teach differently while using current teaching tools.

GnuCash comes with a lot of features, too.
apt-offline version 1.8.4 has been released.
So you want to start developing for Kubernetes, but you don’t want to have to exert the effort to deploy a full-blown Kubernetes cluster to do so. That’s a pretty common problem. And with Kubernetes retiring the support for Docker, you might find a lot of documentation on deploying a Kubernetes cluster to no longer function. On top of that, you might only have a single machine to work with (so deploying an entire cluster can be a challenge).
What do you do? When you only have a single desktop machine, and you need to get this up fast, you can always turn to Microk8s, which is a Cloud Native Computing Foundation-certified upstream Kubernetes platform that you can run from a workstation. Microk8s is easy to get up and running, so you won’t have to waste precious time deploying multiple servers.

In the world of electronic user productivity and consumption devices like mobile phones, tablets, laptops and desktop workstations, everything is about using and managing files. The operating system is based on system files, your movies and music are all files, and the content you create, like letters, presentations, drawings and administration, are stored as files. In this article as part of my free Zorin OS beginner tutorial series I will discuss how to manage your files and folder structures in Zorin OS with the included Gnome Files file manager.
In this tutorial, we will show you how to install Unrar on AlmaLinux 8. For those of you who didn’t know, RAR is the most popular tool for opening, extracting, uncompressing, or unraring an archive file. UNRAR does not come pre-installed natively on AlmaLinux and is not featured in its repositories.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Unrar on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.
You can still load discs into a dedicated player like a caveman if you want, but we live in the age of streaming. Almost every piece of media you could ever want is at your fingertips... as long as you can figure out which streaming service it's currently on. If you care about control, you can manage your own media library with Plex, and the first step in that journey is to decide what kind of hardware will run your Plex server. You can just use your PC, but a dedicated piece of hardware like a NAS box is more efficient. What's a movie buff to do?
As crazy as it may sound, it has been more than four years since we unearthed the container project that would eventually be responsible for bringing Linux to Chromebooks. It has also given us new tools such as Windows on Chrome OS thanks to the efforts of Parallels. When Google first announced Linux on Chromebooks and the ability to leverage the integrated GPUs on Chrome OS devices, my thoughts immediately went to video editing.
Linux can run alongside ChromeOS on your Chromebook, bringing a wide range of apps. Here's the easy way to set it up.
Apache Maven is an open-source tool that allows the building automation of your java projects. It can also be used for projects in C#, Ruby, etc. Its most popular usage would likely involve Java development! The maven project comes from the Apache Software Foundation, where they were previously part of the Jakarta Project before moving on their own clutches.
In the following tutorial, you will learn how to install Apache Maven on Fedora Linux 35.
In literary terms, we can say that the pipeline is a workflow with a group of events or jobs that are chained together and work in a sequence. In other words, its mechanism is similar to a pipe and every pipe has an inlet and an outlet. But what exactly is pipeline still remains a question. The answer to which is that a pipeline will consist of multiple sections of a pipe and can have multiple inlets and outlets where every section processes something and this processing in our case is done by jobs.

Hello Techies, in our previous articles we have learned how to Install Docker on CentOS 8 / RHEL 8 and Docker on Ubuntu 20.04.There are thousand of docker images available on docker hub registry which we can easily pull and spin up container using those images.
But there are some circumstances and use cases that we want to make some configuration or changes in the docker image and those changes should be present whenever we run container. This can be achieved by building a docker image with Dockerfile.
Dockerfile is a text file which contains keywords and set of Linux commands which are executed automatically whenever we build the Docker Image. Creating docker image using Dockerfile is similar to template concept of virtualization world.
In this post, we will learn how to build docker image with Dockerfile. It consists of keywords and Linux commands that are executed during docker build.

As said by Sweeney, the company can’t handle the amount of cheating that occurs in Fortnite especially if it is in a Linux-based OS like in the Steam Deck. Adding to that, the Steam Deck’s OS is based on the Arch Linux system. If you don’t know Linux is an open-source OS and is currently the largest open source project to be used. That means cheaters who have experience with Linux can easily bypass various anti-cheat systems. They can do that if they find a loophole in the Steam Deck.
Valve had previously announced that games that rely on Epic’s own Easy Anti-Cheat system can run on the Steam Deck. Not only that, Heroic, another open-source Linux game launcher can help in running games from the Epic Games Store. So, in a sense, Fortnite can run on the Steam Deck easily and can prevent cheating.
Valve seems to be completely dedicated to making Steam Deck as open and customizable as possible. On top of making its handheld gaming PC run a custom version of GNU/Linux, Valve has now taken things a step further still, as the company has officially released the device's CAD files for anyone and everyone to peruse.
When Valve's Steam Deck begins shipping to customers later this month, the handheld gaming PC will be running a Linux-based operating system called Steam OS. And that could give gaming on Linux a bit of a boost.
As we hit less than two weeks until the Steam Deck launch on February 25, Valve appear to be doing well on the testing front with 520 games now either fully Verified or Playable.
Each day now a good bunch seem to trickle in together. At this rate of progress per-day, we're perhaps going to see close to 1,000 either Verified or Playable by launch. That is, unless this is all still early testing of their processes and we might see a bigger bump closer to launch which is entirely possible. Either way, it's already a rather nice number. The amount only tells so much though, quality over quantity of course and there's a lot of good picks already.
After collecting individual predictions for Linux gaming in 2022, let’s try to look at what the combined predictions look like as well, as we typically see that combining predictions among several people provides better accuracy on average (i.e. the concept known as the wisdom of crowds).
Note that this can only work if everyone has developed their predictions independently from each other’s, which is precisely why we did this time again. Last year we had 7 predictions that stood out, and this year we have 5 of them:
Ready to test some more awesome open source software? Lutris 0.5.10 Beta 1 is out, so this is your chance to help make the next release a polished one. What is Lutris? It's a free and open source application that helps you manage games from Steam, GOG, Humble Store, Emulators, Wine and much more.
You may have seen/heard about the word GNOME when researching Linux. People often refer to it as one of the best Desktop Environments, but what exactly is it? In this article, let’s look at GNOME and its history.
I’m Victoria Martinez de la Cruz, but you can call me Vicky. First time I heard about the open source concept I was pretty young, I’d say, 12 years old. At that time it was quite common to use IRC to chat with friends and to get to know people. And it was precisely in those forums I initially heard the term. I didn’t understand it too well at the time, just knew that there were communities that would work together to deliver quality software and that such software was free to use, read and modify by anyone who wanted to do so. I started learning about different open source software, starting of course by understanding Linux and all the different tools that it constitutes.
When I finished high school, I went to college and signed up to get my degree in Computer Science. Before graduating, I was looking for internship opportunities to get some real world working experience. That’s when I heard about the Gnome Outreach Program for Women (Gnome OPW), nowadays known as Outreachy. I submitted my application to contribute to the GNOME Vinagre project. I didn’t succeed in that opportunity but I applied again the next year, this time for both GNOME Shell and for OpenStack-a fairly new cloud computing project. That is when I started contributing with code to OpenStack.
Like most beginners, I faced so many challenges but I got a lot of help and worked pretty hard to get to success. And it felt really good when I did, considering the amount of work I dedicated for it to happen. My first big win which I don’t take for granted was to be confident enough to pursue the career I wanted. I got several blockers in my path and managed to overcome those, and did that because I was convinced on what I wanted to achieve.
Version 3.4 marks a radical departure from the desktop User Interface (UI) of EasyOS, Quirky and Puppy, right back to the first puppies in 2003. They all have icons on the desktop, since around mid-2005 managed by ROX_Filer -- ROX is not just a file manager, it is also capable of managing desktop icons and wallpaper. ROX-Filer has served us well over the years, in company with the JWM window manager -- the latter managing windows, the system-tray and the menu.
There have been some puppies based on other desktop managers, such as XFCE, however, most of the mainline official pups have been based on the ROX-JWM combo.
For some time I have thought about reducing ROX-Filer to just a file manager. Also, have wondered how the UI could be implemented without desktop icons. EasyOS has desktop icons to launch apps, containers, and mount/unmount drive partitions. If they are eliminated, it means that all of that functionality would have to move into the system tray (or trays).
Early this morning I announced the release of EasyOS 3.4, with radical icon-free desktop. Well, radical for the mainstream EasyOS/Quirky/Puppy releases anyway.
Having been in beta testing, the 64-bit version of Raspberry Pi OS (previously known as Raspbian) is now ready for a wider audience to try out. This will enable users to run 64-bit Linux applications and allocate more memory to individual processes. It also offers improved performance for CPU-intensive tasks.
To use the 64-bit operating system, you will need a Raspberry Pi model with a 64-bit processor. We’ll reveal which models you can use and how to install the OS.
Most recent Raspberry Pi single-board computers have 64-bit processors, but up until recently the Raspberry Pi Foundation’s custom Linux distribution designed for the small, inexpensive PCs was only available in a 32-bit version. But last week saw the official release of Raspberry Pi OS 64-bit, which is compatible with the Raspberry PI 3 and newer devices.
Since March/April 2000 I was deeply involved in Debian m68k and operated multiple m68k autobuilder for over a decade. In fact my Amiga 3000 named “arrakis” was the second buildd for m68k in addition to the Debian owned Amiga 3000UX named “kullervo”.
Back in that time there was some small website running on Kullervo to display some information about the Debian autobuilder. After some time we (as m68k porters) moved that webpage away from Kullervo to my root server. Step by step this site evolved to Buildd.Net and extended to other archs and “suites” beside unstable like backports or non-volatile. The project got more and more complex and beyond my ability to do a complete necessary rewrite.
What a way of starting the year! Setting milestones, helping those in need, and daring to dream. January 2022 starts with one of the biggest technological conferences — CES. So, in this piece, you will find a breakdown of three robots in our usual style. But there’s more… we also bring a story to inspire you all.
It’s a great experience writing this blog, where every month news are abundant. Thank you all for contacting us and sharing your stories.
RISC-V International, the global open hardware standards organization, today announced that Intel Corporation has joined RISC-V International at the premier membership level. “This move demonstrates Intel’s strategic investment in open collaboration and support of the open RISC-V architecture and highlights numerous deep RISC-V member partnerships with Intel,” RISC-V said in its announcement. Bob Brennan, Vice President of Customer Solutions Engineering for Intel Foundry Services, will be joining both the RISC-V Board of Directors and Technical Steering Committee.
All too often, people run into the issue of having many remotely controlled devices scattered around their house, with each requiring its own unique controller. The idea behind how they operate is simple: a single action corresponds to a number and pressing a button on the controller causes that number, along with some extra data, to be modulated via an infrared LED which reaches the device’s receiver. Finally, this value is decoded and the action is executed.
You have a few choices if you want to use a probe to level your 3D printer bed. Rarely, you’ll see optical or capacitive probes. More commonly, though, your probe will sense a metal print or uses a physical probe to touch the print bed. [Design Prototype Test] has long used a BLTouch which uses the latter method. However, putting it in a heated build chamber prevented it from working so he set out to make his own simple design using an Allen key.
We’ve seen Allen key sensors before, but usually, they use a microswitch. We’ve also seen microswitches used to directly probe the bed. But, in this case, a 3D printed fan shroud uses an optical sensor to note when the Allen key hits the bed.
When you need to keep your Raspberry PI aware on where is the North, surely an HMC5883L magnetometer is better that instructing the RPI to look at North Star ðŸâ¢â
In this tutorial, I’m going to show you how to wire, configure and calibrate a magnetometer (HMC5883L) with Raspberry PI computer boards. Please note that if you want to use the Raspberry PI Pico instead, you can refer to my Magnetometer Compass with Raspberry PI Pico: GY-271 HMC5883L wiring and use with MicroPython tutorial.
Shenzhen Xunlong Software previously launched the Orange Pi R1 Plus LTS router board powered by Rockchip RK3328 quad-core processor last November for $27.99 on Aliexpress.
As expected, albeit with some delays, the company has now introduced a metal enclosure for the Orange Pi R1 Plus LTS board transforming it into a complete router or gateway. You can get it as part of a kit for $35.99 plus shipping, or if you’ve already purchased the board previously, get the enclosure only for $9 plus shipping.
Storage isn’t just storage. There is block storage, file storage and, more recently, object storage. And only two of those three are Posix-compliant.
That’s not something most users ever need to know or understand, as long as they can access their data. But it makes a difference to designing and procuring IT infrastructure, especially with the prevalence of the cloud, which is largely based on non-Posix-compliant object storage.
Since the Android build tools already generated a debug signing key for us, we can get the convenience of debug builds for release builds if we configure the build process to sign release builds with our debug signing key. This functionality should be opt-in to avoid signing release builds intended for production with debug keys (see “WARNING” section below) so we’ll add a configuration option to enable this in the uncommitted local.properties file that Android Studio generates.
Software neglect forces perfectly good hardware obsolete. I was suprised it could strike such basic devices as an ethernet switch.
Few years ago I bought a TP-Link gigabit switch for home network. TL-SG2216 model ticked all the boxes: 16 ports, 2 SFP slots (if I ever get FTTH), VLANs, IPv6 support and remote management, 5 years warranty. Although ssh required strange dances since the beginning (ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oCiphers=aes256-cbc -oHostKeyAlgorithms=+ssh-dss …), the HTTPS interface worked fine. Until it broke last year.
Firefox was adamant – SSL_ERROR_NO_CYPHER_OVERLAP. Chromium threw similar tantrum: ERR_SSL_VERSION_OR_CIPHER_MISMATCH. HTTPS management UI on my switch ceased to be secure enough for modern browsers. The world rushed forward, obsoleting and disabling old, unsecure algorthms and protocols. In the meantime my switch stood still. Eventually the world surpassed what was possible with TP-Link.
From my perspective, the web UI broke. I bought a switch with HTTPS management, and this feature stopped working. So, in the last days of my warranty coverage, I reported the issue to TP-Link. Long story short, it was denied on a technicality. I should have opened the issue through the distributor who sold me the switch, not directly with TP-Link. I've got this information after the warranty lapsed, which ended the story.
Firefox is a fantastic open-source web browser. Considering it comes pre-installed with most Linux distributions, it does not take rocket science to assume that it is a popular choice among Linux users and privacy enthusiasts.
However, nothing is ever perfect.
Whether it is Mozilla Firefox, Google Chrome, Brave, or any of the best browsers available for Linux. Every option has a trade-off.
In this second part, we will learn the most basic Calc formulas namely IF, SUMIF and COUNTIF after previously we learned about SUM, COUNT and AVERAGE by examples. These are kinds of formula which often used for decision making, such as making student's grade based on score, and stuffs around that. This tutorial is part of our LibreOffice Calc learning by practices for the formulas often used in jobs. Let's start!
LibreOffice 7.3 was released on 2 February 2022. Here is the official blog post about it. In addition to interoperability improvements with Microsoft’s proprietary file formats, it includes new features targeted at users migrating from Microsoft Office, to simplify the transition. Help has been improved, and change tracking includes new features.
LibreOffice 7.3 is available natively for new Apple computers using Apple Silicon, in addition to those using Intel processors. The minimum operating system requirement for Apple computers is macOS 10.12 (Sierra) and for Microsoft Windows 7 SP1.
I am liking using this new release, but I encountered a bug that caused my MacBook Pro (2017, running macOS 12.2 Monterey) to crash frequently. The problem is easily solved by disabling Skia graphics rendering. Go to LibreOffice > Preferences > LibreOffice > View and uncheck “Use Skia for all rendering” (as shown in the illustration below). This bug does not affect computers running Windows or Linux, and it will be fixed in version 7.3.1.
The new major release of the LibreOffice 7.3 Community, based on the LibreOffice Technology platform for personal productivity on desktop, mobile and cloud, offers a lot of improvements focused on users migrating from Microsoft Office to LibreOffice or exchanging documents between the two office suites.
There are three different kinds of interoperability improvements.
There are performance improvements when opening large DOCX and XLSX/XLSM files, improved rendering speed of some complex documents, and new rendering speed improvements when using the Skia backend introduced with LibreOffice 7.1. Development of new features, such as the new handling of change tracking in tables and when text is moved, which have a positive impact on interoperability with Microsoft Office documents.
The Open Library Foundation has invited the Library Data Platform (LDP) to be the first open source project to participate in its Project Incubation Program. The program is designed to support early-stage open source projects and communities that are developing the balanced and robust mix of technology, governance, resourcing and community engagement required to be self-sustaining.
Godot's code base is split into independent modules that can be enabled and disabled at will. However many games require custom native code and thus need to define their own modules. The simplest way to do this (which, I'm told, game developers quite often do) is to fork the upstream repo and put your your code in it. This works and is a good solution for one-off projects that write all extra code by themselves. This approach also has its downsides. The two major ones are that updating to a newer version of the engine can turn into a rebasing hell and that it is difficult to combine multiple third party modules.
Ideally what you'd want to do is to take upstream Godot and then take a third party module for, say, physics and a second module written by completely different people that does sound effects processing, combine all three and have things just work. Typically those modules are developed in their own repositories. Thus we'd end up with the following kind of a dependency graph.
Addressable LEDs are wonderful things, with products like Neopixels making it easy to create all kinds of vibrant, blinking glowables. However, for those without a lot of electronics experience, using these devices can seem a bit daunting. [Bhavesh Kakwani] is here to help, with his tutorial on getting started with Neopixels using the MicroPython environment.
The tutorial flows on from [Bhavesh’s] Blink example for MicroPython, and is aimed at beginners who are learning for the first time. It explains the theory behind RGB color mixing that allows one to generate all manner of colors with WS2812B-based LED strings, and how to code for the Raspberry Pi Pico to make these LEDs do one’s bidding.
Apache Software Foundation president David Nalley told a Senate hearing Tuesday that "none of the automated tools on the market today" would have caught the Log4j vulnerability prepublication or even very recently.
NetBeans is a development environment written entirely in Java for the programming language developed in Java, languages ââ¬â¹Ã¢â¬â¹such as C, C++, and Fortran are also supported. The architecture of the software is completely modular and can be expanded using so-called modules or plugins. In addition, there are so-called packs, which expand the IDE with larger function packages. Furthermore, NetBeans can be used as a platform for your own applications. Numerous developments and functions from NetBeans were later adopted by other IDEs, e.g. B. by Eclipse. The main focus in the development of NetBeans was on functions that make developers more productive and support them in the technologies that they actually use. The goal is an IDE “from a single source”. For programming, you also need Java SDK here.
When you’re building a quick prototype or a one-off project it’s nice to be able to securely mount the various modules and development boards. Sometimes these boards have mounting holes, but often they don’t. As an example from the latter category, digital music instrument maker and performer [DIYDSP] shows us how to build a simple socket to mount an STM32 Nucleo-32 module.
The socket is built on a standard pad-per-hole piece of vector board cut to the desired size. Pairs of female pin header strips are soldered down to the board. The inner pair of headers is for the module, the outer pair is for your interconnections. The headers are connected up with short solder bridges, and [DIYDSP] recommends you extend the outer pair several pins longer than necessary. These extras can be used for additional power or ground points, or on some boards they could connect to the debug header pins. He prefers to use female sockets because that lessens the odds that an accidentally bent pin will short something out.
2022 is a good year for puzzles, and if you’re getting tired of Wordle, you might be after a new challenge. This color puzzle from [Sebastian Coddington] could be just what you’re looking for.
[Sebastian] describes the 4Ãâ4 Color Dot Puzzle as a sort of combination of the ideas behind the Rubik’s Cube and the 15 puzzle. The aim is to arrange the 16 colored tiles on the board to form four single-colored 2Ãâ2 squares in the overall 4Ãâ4 board. The puzzle is 3D printed, using 6 colors of filament – black for the body of the puzzle, white for the control sticks, and yellow, green, red, and blue for the individual tiles.
My son was into “Secret Coders“, a graphic novel series wherein a pair of kids discover and thwart a plot to take over the world by learning to program in the LOGO computer language. When I told him that these “turtle bots” were originally actually real physical things, he wanted one. So we built one out of some nice geared DC motors I had lying around.
A turtle bot has essentially three jobs: move forward in a straight line a controlled distance, turn a given number of degrees, and raise and lower a pen. If you’re already screaming “use stepper motors!” at your screen, well, you’re probably right. But I had these nice Faulhaber/Micromo geared motors with encoders that were just collecting dust in the closet, so I used ’em. And because of that, the robot stumbles on two of its three goals in life — the servo pen lifter works just fine.
Chromebook shipments collapsed in calendar Q4 as the channel – with an eye on market saturation – ordered in lower volumes and PC makers moved available components to higher-margin builds running on Windows.

In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed. Wireshark is perhaps one of the best open source packet analyzers available today.
