Though it only accounts for a fraction of globally used operating systems, Linux continues to be a prevalent and critical tool for IT administrators and developers.
The open-source software operating system originally released in 1991 is now a large family of variations, giving administrators a range of free and commercial options for managing Linux systems. Servers in particular widely use Linux, thanks to its numerous benefits as an operating system for managing network and infrastructure workloads. In all, Linux is a desirable solution when considering the stability, security, compatibility, and cost benefits for managing modern IT environments.
This article looks at the best Linux distributions, their features, pros and cons, and what to consider when evaluating Linux distros.
Guinness World Records said Thomas Keller and his team at the Center for Data Analytics, Visualization and Simulation, or DAViS, used the software y-cruncher on a machine using the Ubuntu 20.04 operating system to create their precise calculations.
In this video, I will discuss three of the basic command line utilities: cat, tac and tee. These commands are useful for printing the contents of files to standard output and concatenating files.
We all know that linux distros are named but did you know that the kernals also get the same treatment and some of these names are absolutely incredible.
This week’s episode of Destination Linux, we’re going to be discussing lesser known browsers and see which browsers are worthy of checking out. Then we’re going to take a look at the latest innovations coming from VLC. Plus we’ve also got our famous tips, tricks and software picks. All of this and so much more this week on Destination Linux. So whether you’re brand new to Linux and open source or a guru of sudo. This is the podcast for you.
I'm using Steam Deck as my main PC for working and gaming, so I'm making a series of guides (USING THE DECK!) aimed at new Linux users. In this video, learn how to get to Desktop Mode, manage a monitor, and connect up your keyboard, mouse and game controllers.
Hello and welcome to the 458th installment of Linux in the Ham Shack. In this short-topics episode the hosts discuss the rise of the current solar cycle, AMSAT on Discord, GCC and the Linux kernel, Zorin, Sparky Linux, Hamshack Hotline and much more. Thank you for listening and have a great week.
The resurgence of Spectre-like malware has pushed the release date for the next iteration of Linux for at least a week, its creator has confirmed.
In the 5.17-rc8 announcement, the kernel development head Linus Torvalds explained that the discovery of CVE-2021-26341 - a vulnerability in some AMD processors that resembles the dreaded Spectre/Meltdown fiasco, meant the team needed to apply certain patches, which complicated things for the 5.17 version of the OS.
A fact of life, one that almost every computer user has to face at some point, is that file systems fail. Whether it is for an unknown reason, usually explained to managers as Alpha particles flying around the data center, or a more mundane (and way more likely) reason - a software bug - users don't usually enjoy losing their data for no reason. This is why file system developers put a huge effort in not only testing their code, but also in developing tools to recover volumes when they fail. In fact, all persistent file systems deployed in production are accompanied by check and repair tools, usually exposed through the fsck front-end. Some even go a step further with online repair tools.
fsck, the file system check and repair tool, is usually run by an administrator when they suspect the volume to be corrupted, sometimes following a mount command that failed. It is also run at boot-time on every few boots iCollabora, PipeWire, Bluetooth, Fedora 35, WirePlumber, audio layer, policy logic, PulseAudio, comple cameras, libcamera, linux audio, open source software, open source software consultingn almost every distro, through the systemd-fsck service, or equivalent logic.
Indeed, fsck is quite efficient in recovering from errors of several file systems, but it sometimes requires placing the file system offline and either walking through the disk to check for errors, or poking the super block for an error status. It is not the right tool to monitor the health of a file system in real-time, raising alarms and sirens when a problem is detected.
Gabriel Krisman Bertazi describes the new FAN_FS_ERROR event type added to the fanotify mechanism in 5.16.
A new point release for VLC media player 3.0 branch, VLC 3.0.17 is out.
Without any tweak, VLC now support for playing .DAV video files, created via a DVR365 or Dahua Technology digital video recorder (DVR).
The release also features better notch support for new macbooks, adaptive streaming stack overhaul, and major codec updates.
The GStreamer team is pleased to announce the first bug fix release in the stable 1.20 release series of your favourite cross-platform multimedia framework!
This release only contains bugfixes and it should be safe to update from 1.20.0.
Nala is a frontend for APT so that you can have prettier output, faster downloads of packages, and a history. Here’s how to use it.
APT – It’s likely that you’ve typed it hundreds, if not thousands of times. So why not use Nala to make things easier and prettier?
If you’re searching for a more attractive CLI tool to conduct most APT terminal operations, Nala is a good option. In short, Nala is a libapt-pkg frontend.
Sometimes it can be difficult for novice users to comprehend what apt is trying to accomplish while installing or upgrading. And this is where Nala comes on the scene.
The goal of Nala is to fix this problem by removing some redundant messages, improving package formatting, and using color to illustrate what will happen with a package during installation, removal, or upgrade.
In this video, we are looking at how to install FreeCAD on Zorin OS 16. Enjoy!
In this tutorial, we will show you how to install Bagisto on Debian 11. For those of you who didn’t know, Bagisto is a free and open-source e-commerce platform. It is built on various open sources technologies such as Laravel and Vue.js. Bagisto is a hand-tailored eCommerce that allows you to build your online store in no time. It is fast, responsive, beautifully frontend, and easy to use.
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 the Bagisto open-source eCommerce on a Debian 11 (Bullseye).
Today we are looking at how to install Krita 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.
mysqmail-postfix-logger software package provides real-time logging system in MySQL – Postfix traffic-logger. MySQMail is a set of tiny daemon loggers for mail and FTP servers that save traffic information in a MySQL database. The information is split by domain and by user so that it’s easy to measure all the traffic for a given domain name in real time. This package provides a logger for SMTP traffic handled by Postfix.

We self-host Ghost using Docker for our website Linux Handbook.
My colleague Avimanyu has put an excellent mechanism in place that allows updating Docker containers without downtime (if it is set via reverse proxy).
Secure your privacy while surfing online by installing Tor browser on Almalinux 8 RPM-based Linux using command terminal.
When it comes to accessing the notorious dark web standard browsers are not safe without any third-party technology. Well, in such situations the Tor browser is required that uses the Tor network, used by around two million people every day. It is based on Mozilla Firefox. The name Tor was originally an acronym, standing for “The Onion Router”. The reference to an onion was not accidental but was intended to indicate that the Tor network consists of several layers due that users can surf the internet anonymously.
In Tor Network, all data packets are sent from node to node (proxy server) without any point knowing the previous points. You will also receive a random, anonymous IP address. However, there is no 100% security guarantee here either, since every system can potentially be misused by criminals, for example through social engineering or other methods. Not only can you access the dark web with Tor Browser, but you can also surf the regular web. The security is higher, but the speed is lower because of the many diversions.
Disk Partitioning is the process of dividing a disk into one or more logical areas, known as partitions.
Before we can create any files, a filesystem must exist. And for creating a filesystem we must create a partition on our disk.
In this tutorial, we’ll discuss the tools and the process of partitioning disks in Linux. First, we will add a new disk in our server and then create a new partition in it. We will create a partition with both the parted and fdisk commands.
Gentoo is a powerful and extensible Linux distribution. It is one of the few operating systems that stuck to the original source-based package management in Linux. Further, its package manager, portage, is a powerful utility that allows you to fine-tune and tweak each aspect of your distribution.
Lynis is a free and open-source security auditing tool and released as a GPL licensed project and is available for Linux and Unix-based Operating systems like MacOS, FreeBSD, NetBSD, OpenBSD and so on.
Images are the fundamental component of docker. In this guide, we will discuss what docker images are, how to build them, how to manage them, and how to use them.
We previously set up OpenLDAP servers for both CentOS7 and Ubuntu 18.04.9 Even though the setup of OpenLDAP is not on the LFCS exam, setting up a client is on the exam.
Make sure you have two systems you can use for setting up and testing authentication. The systems can be virtual, like VirtualBox.
First, let’s look at some basic setup for both Operating Systems. Then we’ll look at CentOS before we look at Ubuntu, depending on the test OS you are taking or more concerned with learning.
The most appealing aspect of my QDI Advance 5/133 motherboard is its inclusion of AGP, PCI, and ISA expansion slots. This is what allows me to pair a GIGABYTE ATI Rage 128 Pro Ultra AGP video card sold in 2001 with a Creative Labs Sound Blaster 16 WavEffects ISA sound card made in 1997. By having both dedicated MIDI and 3D acceleration hardware I can dip my toes into two different eras of gaming, straddling the divide between Doom and Quake III Arena.
That said I have never been able to get Dave Taylor's original Linux port of Doom to run, as it was built with the deprecated a.out binary format rather than ELF. It would also lack any kind of music playback due to Linux not being supported by the proprietary DMX library used by Doom, although it was for this reason that the Linux source code was chosen for release in late 1997 by id Software to avoid infringing copyright with the DMX code bundled on MS-DOS.
Because of this, Linux users did not have long to wait for a better alternative to arrive, which by the turn of century proved to be LxDoom. LxDoom is derived from the influential Boom source port by TeamTNT, but it still functions very similar to the original Doom port for Linux. Installation is trivial using the lxdoom-1.4.4-0.i386.rpm and lxmusserv-0.94.2-0.i386.rpm packages available for download on SourceForge.
Even though Apex Legends was marked officially Steam Deck Verified by Valve on March 9, that we covered in an article, it's now been updated and it's broken on Steam Deck and Linux desktops.
It's still not really clear what's going on. No announcement was made previously from any party. Valve didn't say anything, Respawn (the developer) didn't and EA (the publisher) also stayed silent. It just seemed to go through Deck Verified, and showed the whole world it worked as it was properly live on the Steam store and in your Steam Library on Deck. Now, a patch came in and it has removed the Linux Easy Anti-Cheat file so the game will boot you out telling you it's not working.
I was wondering recently what the distribution of games validated (i.e. considered as Playable and Verified) for the Steam Deck looked like. Turns out it’s a pretty trivial answer to get, since each appid has a release date (not always the actual release date on Steam, mind you!) that can give us some information about how balanced the Steam Deck line-up is currently.
Snap packages are yet another technology that has been found to be somewhat divisive. From my perspective, bot snap and flatpak have made it possible to install applications on Linux that were not previously available. And given the ease of installing applications with snap, this package management system should be lauded by most as a way to help those unfamiliar with Linux to get up to speed more quickly.
In the past few months I have been developing new generation of Fedora New generation of FMW with a new UI written in Qt6 which will use native QtQuick styles for Windows and MacOS. At this point I have a fully functional application with all the features from the current version.
The application can be now build for Windows and Linux. Linux builds are also available as Flatpak for testing pourpose. Bare in mind this is still not the final version and there still might be some issues.
To develop new generation of FMW I had to learn, rework or update many things. A lot of them I To develop a new generation of FMW I had to learn, rework or update many things. A lot of them I saw for the first time like a complex project, QML, CMake, Qt… First of all I’ve started removing deprecated code that is no longer supported in Qt6 and made sure FMW can be built. After that I could start working on QML. I’ve started making pages and gradually adding basic functionality step by step.
The JingPad A1 is a tablet with premium specs and software that’s both unusual, and unfinished. Launched last year by a Chinese startup called Jingling, the JingPad A1 was designed to run a tablet-friendly Linux distribution called JingOS.
But the company that makes the tablet (and its operating system) has fallen on hard times, putting the future of the JingPad A1 in doubt. Already own one? You may be able to give the tablet new life thanks to a different Linux distribution: You can now install Ubuntu Touch on the JingPad A1 tablet.
Mekotronics is prepping an “R58X” mini-PC that features on an octa-core RK3588 with up to 16GB RAM, 2x GbE, WiFi/BT, HDMI in and out, DP, and 4x USB plus eMMC, SATA, and M.2 storage.
Shenzhen-based Mekotronics has posted several preliminary shopping/product pages (without prices) for an industrial temperature mini-PC and signage player that runs Linux or Android on Rockchip’s octa-core -A76 and -A55 RK3588 SoC. The R58X supports IOT gateway, industrial PC, edge computing, face recognition, digital signage, intelligent device, cloud terminal, and vehicle central control applications, among others.
Vecow’s “ESOM-MT-500” module runs Linux on MediaTek’s octa-core -A73 and -A53 i500 SoC with up to 4GB RAM and 16GB eMMC. A dev kit extends the module with 2x LAN, WiFi/BT, HDMI, MIPI-DSI/CSI, 2x USB, and mini-PCIe.
Last week when we covered Vecow’s first compute module, the Elkhart Lake powered, Compact Type 6 VCOM-1600, we saw that another module was waiting in the wings. Vecow tells us that the ESOM-MT-500 is available now and will be formally announced in the second quarter when it announces additional members of its new ESOM module family.
We're pleased to announce the availability of Datasentinel for PostgreSQL version 2022.02
The GNU Project is a Free Software organization that created the term Open Source that today it is widely used by several companies.
The name GNU is an acronym for: GNU, is Not Unix . And that means:
The commands Unix€© were so successful that many programmers and companies wanted to “copy them” . And most included the name Unix€© in the name itself, examples: HP Unix, Berkeley Unix, … and so on.
But AT&T, the copyright holder of Unix۩ and its name, has prohibited the use of the Unix۩ name for projects similar to it.
You may violently disagree with the inflammatory accusation that comes next, but if this is the case, is there any other word for software that repeatedly surprises its users through frequent design changes than this?: Buggy.
Hello everyone, I am currently working on KConfig bindings for Rust as a part of the Season of KDE 2022. The wrappers for most of the significant aspects of KConfig are complete, so I decided to rewrite the Introduction to KConfig Docs in Rust. The bindings are still not stable and will probably change before the end of the Season of KDE. Still, this post should also help me test out the bindings outside tests. The kconfig bindings can be found here.
The bindings currently use the git version of qttypes since I had to merge some upstream changes that are needed for these bindings. So they are not ready for prime time just yet.
On this Pi Day there is sadly not a lot to report about the Raku Programming Language in the main article of the Rakudo Weekly News.
DingDian S3 is an ultra-compact, pocket-sized mini PC powered by an Intel Pentium Silver N6000 Jasper Lake processor, and equipped with 16GB RAM, and up to 1TB SSD with two M.2 sockets for either SATA or NVMe storage.

Security updates have been issued by Debian (expat, haproxy, libphp-adodb, nbd, and vim), Fedora (chromium, cobbler, firefox, gnutls, linux-firmware, radare2, thunderbird, and usbguard), Mageia (gnutls), Oracle (.NET 5.0, .NET 6.0, .NET Core 3.1, firefox, and kernel), SUSE (firefox, tomcat, and webkit2gtk3), and Ubuntu (libxml2 and nbd).
System administrators make mistakes and that's fine, as long as they learn from them. Learning from your mistakes will develop more skills, advance your career, and make you a better systems admin. However, It’s also helpful to learn from the blunders of others. This is why I’ve compiled a list of common 10 mistakes that system admins make, and how to address these problems.
Fresche Solutions, an IBM solutions provider backed by private equity firms American Pacific Group (APG) and Northstar Capital, has acquired security, auditing and detection software and services company Trinity Guard. Financial terms of the deal were not disclosed.
In my last post I talked about the privacy issues from static public WebID in Solid. In this post I am trying to explain a way to preserve privacy, I will later submit a proposal (after figuring out how to) to change/update the original SPECs as required.
[...]
That can be done by marking one client as the primary viewer/editor for the user, you can think it like a wallet. This solid application will be able to get the original unique WebID, and using that in the user's pod the wallet can find all the issued WebIDs. This goes into the implementation details of the pod server. Maybe all targeted WebIDs (& related pods) will be stored in a different namespace, maybe not.
Deere & Company is stating that tractors are like aircraft in their complexity. I laughed at the thought of a flying tractor. But apart from the visual joke, the analogy makes Deere’s repair restrictions seem even more absurd.
Modern tractors are full of computers, just like aircraft, cars, and data centers. Putting a computer chip in a tractor doesn’t make it fly like an aircraft but does make it function just as a mainframe computer with multiple controllers and peripherals in a data center. Keeping that equipment up and running is a critical part of design as every farmer, pilot and computer geek knows.
In the computer industry as with aircraft, uptime—aka “High Availability”—is essential. Yet Deere has been building products using hundreds, if not thousands, of parts, any one of which is a single point of failure, and then tying the replacement of those parts to their exclusive control. Every delay created by this service model becomes a critical issue for farmers.
Aircraft are full of redundant sensors for this very reason. Data center storage is “redundant,” “hot swappable,” and “plug and play”—techniques that have allowed for the exceptional uptime that we have come to expect in the air and online. Despite the opportunity to learn from both the airline industry and data center computing, Deere has designed equipment using hundreds of small sensors without building the redundancy needed for producers to keep rolling in the event of a component failure.
