Welcome to this week's Linux Weekly Roundup, we had a wonderful full week in the world of Linux releases with Nitrux 2022.02.28, openSUSE 15.4 beta, Voyager Live 22.04 Alpha, Freespire 8.2, and Endless OS 4.0.3.
If you’re lucky enough to own the modular marvel that is the Framework laptop you’ll be thrilled to know that Ubuntu finally “just works” on the device.
Ubuntu did, of course, work prior to now as well, but some of the laptop’s uniquely-upgradable hardware was not supported ‘out-of-the-box’. Many of those looking to run the latest LTS release on the device had to perform a few manual interventions to get core features, including the Wi-Fi and fingerprint reader, working as intended.
The AUR being the Arch User Repository is designed for use around Arch Linux and when you use it on anything else even something Arch based you may face depending on the configuration of that distros repos.

In this episode we discuss our current daily driver distros of choice and pick alternatives that we would move to if our current distros of choice stopped being developed.
Peppermint OS 11 makes massive changes in form of the new Debian Base and Unified XFCE desktop. The system that is famous for its super-fast performance is now reborn with an even robust engine under the hood and a completely revamped experience for its users.
No surprises this week - we still have a couple of pending things, but everything looks under control.
Knock wood.
Last week saw the usual number of small fixes all over - with btrfs standing out once again. But once again it's not like it's a lot of changes, it's just that the rest tends to be pretty small.
"The rest" in this case is mostly networking (drivers but also some core fixes), misc other drivers (gpu and input, with some noise elsewhere) and arch updates (mostly devicetree and some kvm fixes, but also RISC-V and s390).
Shortlog appended - and as things stand, I expect that final 5.17 will be next weekend unless something surprising comes up.
Please test,

I am considering an additional article to my Slackware Cloud Server series.
As I showed in that series, a Nextcloud server can be equipped with capable text, voice and video communication apps but they are self-contained. The Jitsi Meet stack contains an internal XMPP communication server and Nextcloud collabration apps can only connect to user accounts on other Nextcloud server instances (through a process called federation). What if you wanted to collaborate with people on other networks, say, other clouds? In the past I would be quick to point to XMPP server solutions like Jabber but those seem to be disappearing. Two popular platforms exist which use completely different protocols: Matrix.org is built on top of its own Matrix open standard and Rocket.chat. is built with the Meteor JavaScript platform. These two also use federation to connect to other instances of their own product but on top of that, these servers offer bridges to a whole lot of other communication platforms, such as Teams, WhatsApp, IRC, Slack etc.
How well do these two integrate with Nextcloud? On my own cloud server (based on the Nextcloud platform) I installed Element for Nextcloud, which is an app to use the Matrix.org web client called Element (formerly riot.chat). Element can connect to existing Matrix.org servers out there, or you can setup a Matrix server yourself. And then there is an alpha-quality app to integrate Rocket.chat into Nextcloud but it is not advised to install that on anything else than a testing environment. Worth mentioning: both Matrix.org and Rocket.chat offer seamless integration of the Jitsi collaboration platform which is also covered in great detail in my article series.
Accountancy is the measurement, processing, and communication of financial and non financial information about economic entities such as businesses and corporations.
Accounting software is a computer program that assists bookkeepers and accountants in recording and reporting a firm’s financial transactions. The functionality of accounting software differs from product to product.
There’s a fair degree of overlap between personal finance software and accounting software. Both often provide double-entry bookkeeping functionality. The ratings featured here consider only the accountancy aspects of software. For example, you’ll notice GnuCash that scores much higher as a personal finance tool.
Here is our opinion on the finest accountancy software available for Linux. We only include free and open source software.
As files in your devices increase, a common limitation is having a cloud storage to get your files securely stored and available for your access and collaboration. Common storage services (like Google Drive or One Drive) give you few space compared with modern needs and require a fee for bigger GigaBytes. Seafile with Raspberry PI can give a cheap solution with cross device clients
In this tutorial, I’m going to show you how to install and configure Seafile with Raspberry PI by using Docker, which makes far simpler the installation procedure.
Similar to GRR, Velociraptor also allows for hunting across many thousands of machines. Inspired by OSQuery, Velociraptor implements a new query language dubbed VQL (Velociraptor Query Language) which is similar to SQL but extends the query language in a more powerful way. Velociraptor also emphasizes ease of installation and very low latency — typically collecting artifacts from thousands of endpoints in a matter of seconds.
In this article we will learn How to Permanently Disable Swap in Linux. Swap space represents a physical memory page that lives on top of disk partition or a special disk file used for extending the RAM memory of a system when the physical memory fills up.
In this article we will learn How to Setup Openshift Origin on CentOS 8.
OpenShift is an open-source PaaS platform that allows you to deploy an application on the cloud. It supports many programming languages including, Python, PHP, Perl, Node.js, Ruby, and Java. You can also add support for other languages. It is specially designed for a high-availability and scalable application platform. Moreover, It provides an easy way to scale your application as per your demand with zero downtime. It provides a powerful web UI that helps you to monitor container resources, container health, and the IP address of nodes.
In this article we will learn how to Install and configure Kernel Crash Dump on Centos 8.
Kdump is a service providing a crash dumping mechanism. The service enables you to save the contents of the system’s memory for later analysis. kdump uses the kexec system call to boot into the second kernel (a capture kernel) without rebooting; and then captures the contents of the crashed kernel’s memory (a crash dump or a vmcore) and saves it. The second kernel resides in a reserved part of the system memory.
Learn the commands to install open source LibreWolf browser on Ubuntu 20.04 Focal Fossa LTS Linux using command terminal.
What is LibreWorf?
LibreWolf is an open-source browser based on Firefox. This means you will get the performance and stability of the popular Mozilla browser. Along with that, the key focus of the LibreWolf developers is to provide protection against tracking, fingerprinting techniques along with other few security improvements. It also aims to remove all the telemetry, data collection, and annoyances, as well as disabling anti-freedom features like DRM.
By far the biggest LVM Cache surprise is just how well it works.
Between 2010 and 2020, my single, biggest and most consistent headache managing servers at May First has been disk i/o. We run a number of physical hosts with encrypted disks, with each providing a dozen or so sundry KVM guests. And they consume a lot of disk i/o.
This problem kept me awake at night and made me want to put my head on the table and cry during the day as I monitored the output of vmstat 1 and watched each disk i/o death spiral unfold.
We tried everything. Turned off fsck’s, turned off RAID monthly checks. Switched to less intensive backup systems. Added solid state drives and tried to stragically distribute them to our database partitions and other read/write heavy services. Added tmpfs file systems where it was possible.
But, the sad truth was: we simply did not have the resources to pay for the infrastructure that could support the disk i/o our services demanded.
Then, we discovered LVM caching (cue Hallelujah). We starting provisioning SSD partitions to back up our busiest spinning disk logical volumes and presto. Ten years of agony gone like a poof of smoke!
I don’t know which individuals are responsible for writing the LVM caching code but if you see this: THANK YOU! Your contributions to the world are noticed, appreciated and have had an enormous impact on at least one individual.
In this article, we will be discussing the deletion of schema from our database. Database Schemas are a group of objects of databases that hold almost every element that the database should have, like triggers, functions, tables, and predefined procedures. In PostgreSQL, only the owner or superuser may remove a schema. There are several checkpoints that we have to go through when we delete a schema; these checks will be discussed further in this article.
Today we are looking at how to install Quadrapassel, a Tetris game, on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
The Raspberry Pi is a mini-computer board that contains RAM, a processor, and other peripheral device connections that are required by the personal computer. These boards were initially launched for the understanding of computer usage on the school teaching level but later on, these boards were used for different electronic projects.
The Raspberry Pi has launched different boards like Raspberry Pi 2 and Raspberry Pi 4 which have different technical specifications. In this write-up, we will understand the methods to identify the RAM chip on the Raspberry Pi board.
In this tutorial, we will show you how to install Drupal on AlmaLinux 8. For those of you who didn’t know, Drupal is an open-source and popular content management tool with a large, supportive community. It’s used by millions of people and organizations around the globe to build and maintain their websites.
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 Drupal on an AlmaLinux 8. You can follow the same instructions for Fedora, RHEL, CentOS, and Rocky Linux distributions.
Data in the PostgreSQL database management system is stored in the form of tables. Each table is created in the database. The record inside the database in the form of tables can be moved from one database to another and in the same database as well. This guide will cover some methodology of creating a new database and then copying the relation in one database to the new one.
To start the steps, open the PostgreSQL shell. It will demand the database name, username, and password for the verification. The password is a mandatory field to proceed further. After that, you are connected to the database created already.
Need to run Windows programs on Linux? Bottles can help with that! Bottles is a frontend to WINE. Choose between Gaming and Software environment based on the type of software you want to start. More advanced users can choose the Custom environment to configure the bottle on their own.

Have you ever wanted to share a file on your local area network with another user and make that file available with no network restriction for Windows, macOS, and Linux systems?
This article will give you a step-by-step guide on installing and setting up Samba file sharing on RHEL 8 distros, such as CentOS 8, Rocky Linux 8, and AlmaLinux 8.
That will give other users on your LAN easy access to your files. Samba is a free software application that helps Linux servers to share resources and files with other clients such as windows clients, Mac, and other distributions.
Samba applications use TCP/IP for sharing data between the cross-platform servers. It is implemented using CIFS and SMB protocols. CIFS stands for Common Internet File System, while SMB stands for Server Message Block.
When you run the lsblk -l or df -h command to list out the available block/storage devices, you may find the /dev/loop filesystem, especially if you are using the Snap package manager, and it’s quite common to find in Ubuntu distributions.
If you are keen on knowing what loop devices are and how to mount and unmount them from the system, then this article will be enough for you.
because it will cover all the necessary aspects of loop devices, like how to create a loop device, loop filesystem, mounting, and unmounting steps.
Valve's Steam Deck is here and, since we’ve had our hands on it, we’ve discovered several little things - both good and bad - that it can and cannot do.
Here’s a round-up of the most unexpected things we discovered during our first few weeks with the Steam Deck. Please take note of time of publish, as we’ve discovered the Steam Deck is constantly evolving and some of these may change in the future (wanna know how it's evolving? Check out our review-in-progress).
Want to transfer files to and from your PC to a Steam Deck? It's easy and here's how you can do it in a few minutes.
Something I've seen asked a lot directly to me, and across numerous posts on Reddit so hopefully this will help. This way requires no extra hardware, you just need to ensure your devices are on the same network and that's all.
Following the recent releases of DXVK 1.10 and VKD3D-Proton 2.6 this past week, DXVK-NVAPI 0.5.3 is out this Sunday as the newest update to this library providing NVIDIA driver API "NVAPI" integration around DXVK/VKD3D-Proton for Windows games running on Linux by way of Steam Play (Proton).
Budgie 10.6 is here 11 months after version 10.5.3 and introduces improvements to application grouping, improvements to single-instance application tracking, better support for some KDE applications, as well as a revamped notification system that’s now standalone and is no longer part of the Raven notification center, paving the way for new features like support for notification badges in the icon tasklist.
Coming just one and a half months after version 7.5, digiKam 7.6 is here to introduce a new Flow View plugin based on Masonry layouts, a grid layout based on columns designed to optimize the use of space inside a canvas.
Users interested in using this third-party plugin can access it from the View menu in all digiKam main windows, as well as in the Showfoto image editor component. However, you should keep in mind that the plugin is not considered mature due to the fact that it can’t display any metadata or details from items.
KDE produces amazing software, but sometimes not everyone can use it.
One of the reasons that can happen is because it's not translated to a language they understand.
For that we are calling for translators, specially for the languages listed below which had not had a single translation update in the last year [*].
Committing to help means that you will do some work every now and then, not just translate a few texts only.
My work centres around alerts in KDE Connect iOS app. As it’s under development, a lot of information is communicated to the user using system alerts. iOS is limited to displaying only one alert at a time and doesn’t have any native system for queuing them.
After 10 years of development, the Qt based graphical MPD client Cantata finally discontinued.
Cantata is a free open source graphical client for MPD, features multiple MPD collections, highly customizable layout, MPRISv2 DBUS interface, Jamendo, Magnatune, SoundCloud, and Podcasts support.
The source code of the project has been archived for a period of time after version 2.4.2. By releasing Cantata 2.5.0, the developer finally announced that the development of Cantata has now ceased!
This is my third blogpost for SoK 2022.
If you have been following my earlier blogposts, you would know that I’ve been working on adding the Perspective Ellipse Assistant Tool in Krita.
The 64-bit version of the official Raspberry Pi OS (previously known as Raspbian) operating system is now available to install using the standard Raspberry Pi Imager tool. But why should you opt to use it rather than the standard 32-bit operating system?
Here, we will take a look at the advantages, and minor downsides, and some of the use cases for using Raspberry Pi OS 64-bit.
Argon Forty loves releasing cases with names that have permutations of the word “ONE.” So far we’ve had the Argon ONE (and M.2), NEO and now we have the EON. But rather than another wedge shaped Raspberry Pi case bound for our desktop, the EON is bound for our living room, office or small business where it helps turn your Pi into a network-attached storage drive (NAS).
The $150 Argon EON, which goes on sale in mid March 2022, is a delightfully designed Raspberry Pi 4 case that has better aesthetics than many of the best Raspberry Pi Cases. Made from space-grade aluminum, this cyberpunk influenced aesthetic is right at home in our lives. Inside we can store up to four 2.5 inch drives, or two 3.5 inch drives, and running the show is our favorite single board computer, the Raspberry Pi 4.
The Argon EON kickstarter was successfully funded in September 2021, with backers receiving their units in early 2022. Argon Forty raised HK$ 1,177,230 (approximately $150,609) from over one thousand backers. Ahead of the retail release we secured an Argon EON for review and put it through its paces during a week of tests and typical work scenarios.
Leonardo and I are pleased to another update to our nanotime package bringing it to version 0.3.6 which landed on CRAN earlier today.
nanotime relies on the RcppCCTZ package (as well as the RcppDate package for additional C++ operations) and offers efficient high(er) resolution time parsing and formatting up to nanosecond resolution, and the bit64 package for the actual integer64 arithmetic. Initially implemented using the S3 system, it has benefitted greatly from a rigorous refactoring by Leonardo who not only rejigged nanotime internals in S4 but also added new S4 types for periods, intervals and durations.
In which we search for a needle in a lendee (or maybe a chatchka in a haystack), and delight in some lazy CPAN comfort.
Encapsulation is one of the most significant concepts of object-oriented programming that provides security by hiding the sensitive data/implementation details of the class from the users. In Java, encapsulation can be achieved by declaring the class attributes/variables as private. In certain cases, we need to access or modify the private variables, so in such a scenario, we can use the public get and set methods.
Object-oriented programming provides a concept of constructors that allows us to initialize the newly created objects. A constructor is a special type of method/function having the same name as the class name and a constructor doesn’t have a return type.
Object-oriented programming has four primary/fundamental concepts i.e. inheritance, encapsulation, abstraction, and polymorphism, and all these concepts revolve around the classes and objects. A class is a blueprint/template that represents the properties and behavior of the objects while the objects are instances of a class. In java, defining the class wouldn’t take any memory until an object of the class is created.
In Java, a method is nothing but a block of code/statement that is declared within the class and can perform different actions when someone calls it. Some methods can be called directly with their name (i.e. without creating the class object) while some methods require instance/object of the class (i.e. must be invoked with the object of the class).
The methods that can be called directly are referred as a class or static methods, while the methods that need an object of the class to be invoked are referred as instance or non-static methods.
Data Abstraction is one of the most important concepts of OOP that shows only essential details to the user and hides the desired details from the users. All in all the main purpose of abstraction is to provide security.
The best example of abstraction can be an ATM machine which can be used for cash transfer, withdrawal, inquiring account balance, etc. We utilize ATM machines to achieve different functionalities but when we put the card in the ATM, we have no idea what operations are happening within the ATM machine. That’s exactly what abstraction classes, methods, and interfaces do in Java.
