According to Juno Computers, all the video ports in the laptop are controlled by the NVIDIA GPU.
Many Linux distros have now started developing their own desktop environments. Why is this so? Let's find out.
Most of us don't think of the desktop as something separate from the operating system. What you see on the screen—that is Windows or that is macOS. But on Linux, there is no one desktop. Instead, there are many.
Most people stick with what comes by default, and a number of Linux distributors are opting to create their own desktop from scratch. elementary OS has Pantheon. Solus has Budgie. System76 has COSMIC. Nitrux Linux has Maui Shell. In the past, Ubuntu had Unity.
I received a new laptop for work - a Dell XPS 13. Dell has been long famous for offering certain models with pre-installed Linux as a supported option, and opting for those is nice for moving some euros/dollars from certain PC desktop OS monopoly towards Linux desktop engineering costs. Notably Lenovo also offers Ubuntu and Fedora options on many models these days (like Carbon X1 and P15 Gen 2).

Obviously a smooth, ready-to-rock Ubuntu installation is nice for most people already, but I need openSUSE, so after checking everything is fine with Ubuntu, I continued to install openSUSE Tumbleweed as a dual boot option. As I’m a funny little tinkerer, I obviously went with some special things
Yes, that's right. Valve confirmed the Steam Deck's release date. It's February 25th, 2022. That's just under a month away from the release of this video.
Stefano Maffulli joins Jonathan Bennett and Simon Phipps on this episode of FLOSS Weekly. Phipps does double duty as guest as well as co-host. It's all about the Open Source Initiative, the custodians of what exactly counts as Open Source. That may seem like a solved problem, but cloud computing, machine learning, and Standard Essential Patents present new challenges to face. We talk about these topics and more, so check it out!
There see to be some legitimate concerns with how the FSF approaches microcode and firmware running on a secondary processor which does not respect your freedom and in many ways puts users in danger.
We've got a very special laptop running Linux out of the box: the StarLabs Starbook Mark 5. This one is pretty different from virtually every other manufacturer: it's NOT using a clevo or tongfang chassis, it's custom designed, aluminium, and it's a pretty amazing ultrabook that really deserves an in depth look.
LibreNMS is a monitoring tool that supports auto-discovery with multiple protocols, including SNMP, ARP, OSPF, and BGP. To monitor operating systems, you can use the SNMP protocol, which is available on most OS, including Linux, Windows, and BSDs.
There are three versions of SNMP Protocol, v1 and v2 which are secured with only a community password, and the protocol v3 which supports passwords for authentication and encryption. For the production environment, it's recommended to use the SNMP protocol v3, which is more secure than v2 and v1.
In this article, you will learn how to add hosts to the LibreNMS monitoring system using the SNMP protocol.

Apache Cassandra is an open-source distributed database developed for cloud computing. It provides a highly available and scalable database service with no single point of failure and no manual tuning.
Apache Cassandra is one of the most popular databases used in artificial intelligence to help create robots. With the ability to scale up quickly using commodity hardware, Cassandra could become one of the primary data storage systems that will power future robotic data management devices.
Apache Cassandra is a NoSQL database. With the addition of the Apache Thrift interface, Cassandra can be used to store and manage data without the use of SQL, while allowing developers to use familiar application development protocols like REST and Thrift.
Cassandra was primarily developed by Facebook engineer Prashant Malik. The database was named after the wife of a co-founder of Facebook, who died in a car accident in 2008. It is built on Google’s BigTable architecture, with support for distribution, replication, failure detection and load balancing using Apache ZooKeeper.

If you are a traditional programmer, using bash for scripting may seem limiting sometimes, but for certain tasks, bash can be very productive. It turns out, some of the limits of bash are really limits of older shells and people code to that to be compatible. Still other perceived issues are because some of the advanced functions in bash are arcane or confusing.
Strings are a good example. You don’t think of bash as a string manipulation language, but it has many powerful ways to handle strings. In fact, it may have too many ways, since the functionality winds up in more than one place. Of course, you can also call out to programs, and sometimes it is just easier to make a call to an awk or Python script to do the heavy lifting.
Sail is a great and much more affordable alternative to traditional and managed WordPress hosting. It’s a free and open source CLI tool to provision and manage WordPress applications in the DigitalOcean cloud.
There is a local privilege escalation in Polkit (formerly PolicyKit, and used in plenty of places where privilege escalation is needed). It was found by Qualys, and carefully documented on the oss-sec mailing list. It has hit the mainstream media fairly hard, too – probably because it follows closely on unrelated log4j and faker.js issues in Open-Source-land. I’m not a security specialist by a long shot (not by at least 3 light-seconds, even), but let’s take a brief look at execve() in FreeBSD.
MongoDB was first developed in 2007 by Dwight Merriman and Eliot Horowitz when they experienced scalability issues with relational databases while developing enterprise web applications at their company, known as DoubleClick. According to one of the developers, its name was derived from the word humongous to support the idea of processing a large amount of data.
Monitorix is a free and Open-source, lightweight system monitoring tool designed to monitor services, system resources, and servers. It is similar to Zabbix, Nagios, and Cacti.

You can automate simple tasks like installing packages, or complex workflows such as deploying a clustered solution with multiple nodes or patching your operating system with many steps. Whether the workflows are simple or complex, you need to integrate appropriate optimization techniques into the Ansible playbook content.
This article covers some of the major optimization methods available in Ansible for speeding up playbook execution.
Linux kernel 5.16 has many new features, support, and security. The Linux 5.16 kernel release has a great new feature, FUTEX2, or futex_watv(), which aims to improve the Linux gaming experience, growing considerably with better native Linux porting for Windows games utilizing Wine.
Other improvements have seen improved write congestion management task scheduler for CPU clusters sharing L2/L3 cache, among others. More information can be found on the Linux 5.16 Kernel release changelog.
In the following tutorial, you will learn how to install the latest 5.16/5.17 Linux Kernel on Fedora 34/35 Server or Workstation using the Linux Vanilla third-party repository that is well known.
Essential networking devices, network services, and applications need constant monitoring to lessen the troubleshooting complexities that many server administrators have to endure or overcome.
One reputable tool for managing such networking footprints is Nagios. Its active monitoring functionality can detect network devices, services, and application faults on a server it is tasked to monitor. Once such faults are detected, the administrative user is notified of the underlying suspicious activity on the network.
The machine that hosts Nagios should embrace a Server/Agent architecture for it to comfortably communicate with remote hosts that need constant monitoring.
This Nagios network monitoring tool makes use of agents like Nagios Remote Plugin Executor for swift communication with remote hosts. Moreover, Nagios generates final reports from visually represented user interface logs.
In this tutorial, we are going to learn how to install Portainer CE with Docker-compose.
Portainer is a free and open-source lightweight service delivery platform for containerized applications that can be used to manage Docker, Kubernetes, Docker swarm, etc. The application is simple to deploy and use. The application allows you to manage all your container services via smart GUIs or an extensive API, this makes the developers’ work easier.
Portainer gives developers a chance to deploy, manage, and troubleshoot containerized applications without needing to deeply have experience with Kubernetes. This is awesome in my view.
In this tutorial we are going to learn how to install Portainer inside a docker container, also we will learn the uses of Portainer, what are Portainer agents. Also, we need to understand about Portainer ports i.e which ports do Portainer uses to communicate with the world. So let’s dive in
We have two editions of Portainer, the Portainer community edition which is free to use, and the Portainer Business Edition which requires one to purchase the license fee to use and has more features compared to the community edition.
Are you a gamer or want to play the game and use Ubuntu then Gamebuntu is for you. Gamebuntu is an all-in-one app that makes it possible to play games with just a single click of installation.

 Announced in July 2021, Steam Deck promises to be a revolutionary gaming handheld powered by Valve’s SteamOS 3.0 operating system based on Arch Linux and featuring the KDE Plasma desktop environment.
Initially planned for the end of 2021, Valve delayed their upcoming Steam Deck device for February 2022, but now the company has finally revealed the official release date as February 25th.
A little flying-disc on the go when you get your shiny Steam Deck? Windjammers 2 is out from Dotemu and it's absolutely brilliant, although I am completely horrible at it.
Valve continue burning the midnight oil as it's getting close to the Steam Deck launch now. Their classics continue getting updated, with Half-Life 2 getting a new UI.
While they've already added Vulkan support to multiple older titles using DXVK-Native, it appears they're now moving on to make more changes to help players on gamepads work with their games. It makes sense of course, since having their own games work great on the Steam Deck is a must.
Serious Sam: Siberian Mayhem is out now as a partnership between Timelock Studio and Croteam. It can run rather well on Linux, although you do need a quick adjustment for Steam Play Proton.
This is a much shorter and simpler game than previous entries, as it's a sort-of standalone expansion that sits together with Serious Sam 4. Although, going in cold is not a big deal, since it's mostly the usual mindless fast-paced shooting you would expect from a Serious Sam game. The game actually started off life from a modding team, who under guidance from Croteam, turned it into an official game in the series.
It’s time again to use the fabulous ProtonDB to find out some cool stuff. Today, we can look at what are the most wanted games (by using the number of people submitting reports) for which the ratings are abysmal, as in 100% borked. And you end up with the Top 10 that follows. Let’s go from the least popular ones to the most popular ones – for each game we will also give you a quick comment about why it fails currently.

Effectively mitigating risk is a growing challenge for business and IT leaders. Consider these tips on how to offset risk in 4 essential areas
Don't miss a thing! Here's a roundup of new articles, tutorials, and more published this month on Red Hat Developer.
Quarkus is a foundation for building Java based applications; whether for the desktop, server or cloud. An excellent write up on usage can be found at https://fedoramagazine.org/using-the-quarkus-framework-on-fedora-silverblue-just-a-quick-look/. This article is primer for coding asynchronous processes using Quarkus and Mutiny.
So what is Mutiny? Mutiny allows streaming of objects in an event driven flow. The stream might originate from a local process or something remote like a database. Mutiny streaming is accomplished by either a Uni or a Multi object. We are using the Uni to stream one object — a List containing many integers. A subscribe pattern initiates the stream.
A traditional program is executed and results are returned before continuing. Mutiny can easily support non-blocking code to run processes concurrently. RxJava, ReactiveX and even native Java are alternatives. Mutiny is easy to use (the exposed API is minimal) and it is the default in many of the Quarkus extensions. The two extensions used are quarkus-mutiny and quarkus-vertx. Vert.x is the underlying framework wrapped by Quarkus. The Promise classes are supplied by quarkus-vertx. A promise returns a Uni stream when the process is complete. To get started, install a Java JDK and Maven.

Containers are the default way of packaging software in the cloud. Amazon Web Services (AWS) executive Deepak Singh shares insights for IT leaders on smoothly running containers with its service and ecosystem partners
Once upon a time in the 2000s and 2010s, Patrick McHardy was the chair of Linux's Netfilter core development team. Netfilter is a Linux kernel utility that handles various network functions, such as facilitating Network Address Translation (NAT) and Linux's IPTables firewall. All was fine. But, then it was discovered that McHardy had made millions of Euros from threatening over 50 companies with legal action for using "his" code. That will never happen again.
McHardy was suspended from the Netfilter team in 2016. The Netfilter team released a document on how to deal with his attempts to extract money from vendors. This move by McHardy, who had been a leading Linux developer in the 2000s, came as a complete surprise at the time. Now, years later, the issue has finally been resolved.
Fedora is a Linux operating system. The computers we have at home are similar it has an operating system called windows, Fedora is just another one like windows just with differnt features. the operating system tells the computer what to do when you move the mouse or press a key on the keyboard. e.t.c .
So just like we have operating systems for phone like iphone and android, we also have different ones for computers like MacOS, Windows, Fedora Linux e.t.c.
Now to do anything more with your computer you need to have aplications just like whatsapp and twitter on our phones, on the compter you can have web browser that lets you access youtube, whatsapp e.t.c. the process of adding new applications to your phone or computer is called installing.
For this internship program i make lots of applications easy to install on the Fedora Linux operating system.
I got this internship through Outreachy.
[...]
Outreachy has vast list of projects to work on but i chose Fedora and i am loving the experience so far, and i am hoping even after the internship i will still be an active contributor to Fedora.
The Linux Foundation has published three new courses on the platform edX with which their corresponding certificates can be obtained.
For those who are lost, edX is a MOOC platform created by the Massachusetts Institute of Technology (MIT) and Harvard University. It runs on its own platform technology, edX, which is published as open source on GitHub. It has a close relationship with The Linux Foundation and stands out for making courses related to Open Source technologies available.
We are very happy to announce that the Qt Developer Conference is back on track after having been postponed last September. Mark your calendars and save the date on 13th-15th June 2022. This will be our first in-person event since the pandemic started. Do not miss out on this wonderful experience!
Last spring, we brought you Tediumââ¬Â²s version of a clip show for our 500-ish issue. In that issue, we did a few updates, curated a “best-of” celebration for that landmark issue of the newsletter (although in my head, Tedium is more of what I’ve always wanted a magazine to be). Recently, I found myself thinking about all the stories I wanted to do but just couldn’t manage to put together enough for a full-fledged Tedium piece. I originally planned to bring you a story about pressure washers—and I assure you it is coming—but time and fate just weren’t on my side to get that together in time. So, I turned my attention to some unfinished thoughts and ideas to flesh them out a little more. Today we’re bringing you a series of mini-pieces about topics that are interesting, but not quite enough to fill out an entire issue. Expect some music, thoughts about nostalgia, and perhaps an idea of what the future might hold.
According to the researchers, the vulnerability (CVE-2021-4034) was discovered in PolicyKit’s pkexec tool, which incorrectly handled command-line arguments. This could lead to local privilege escalation, allowing any regular user in a GNU/Linux distribution to gain administrative privileges and run programs as an administrator (root).
The good news is that most major GNU/Linux distributions already received patched versions of the Polkit package. At the moment of writing, Debian published patches for Debian GNU/Linux 10 “Buster” and Debian GNU/Linux 11 “Bullseye” systems, and Canonical published patches for all of its supported Ubuntu releases.
A 12-year-old security vulnerability has been disclosed in the Linux’s system utility Polkit that grants attackers root privileges.
Previously called PolicyKit, Polkit manages system-wide privileges in Linux. It provides a mechanism for nonprivileged processes to safely interact with privileged processes and it’s installed by default in every major Linux distribution.
Yesterday, researchers from Qualys published an advisory about a local privilege escalation vulnerability in the pkexec tool, that is installed as part of the Polkit. The pkexec tool, which is a command line tool, is used to define which authorized user can execute a program as another user.
Linux users on Tuesday got a major dose of bad news—a 12-year-old vulnerability in a system tool called Polkit gives attackers unfettered root privileges on machines running any major distribution of the open source operating system.
One of the major reasons behind choosing Linux as an operating system is that it’s much more secure than Windows. There are plenty of reasons for this including appropriate user permissions, installing software from trusted sources and, of course, the fact that most software for Linux including the Linux kernel itself is open source which allows anyone to review the code for vulnerabilities. This doesn’t mean that Linux is perfectly secure though, as researchers recently found a major bug found in most major Linux distributions that allows anyone to run code as the root user.
The Electronic Frontier Foundation is taking the Digital Millennium Copyright Act to court. This is nothing new. EFF has been fighting selected aspects of the DMCA since before the act was passed in 1998.
In this case, EFF is taking aim at provisions of the law that have in recent years become specifically problematic for the right-to-repair movement. These revolve around the DMCA’s Section 1201, which makes it illegal for users to find ways to bypass Digital Rights Management software to access copyrighted material, even when they legally own it.
On January 12, EFF and co-counsel Wilson Sonsini Goodrich & Rosati asked the U.S. Court of Appeals for the District of Columbia to reverse a district court decision in Green versus DOJ, which was a suit filed in 2016 by EFF challenging the anti-circumvention and anti-trafficking provisions of the DMCA on behalf of security researcher Matt Green and technologist Andrew “bunnie” Huang.
According to EFF, both are pursuing projects that are not only beneficial to the public, but would be completely lawful if not for the DMCA’s anti-speech provisions, which EFF says violate the First Amendment.
[...]
In some cases, even telling someone how to fix a problem is a criminal act, according to EFF.
“Section 1201 makes it a federal crime for our clients, and others like them, to exercise their right to free expression by engaging in research, creating software, and publish their work,” EFF senior staff attorney Kit Walsh said in a statement. “This creates a censorship regime under the guise of copyright law that cannot be squared with the First Amendment.”
