Articles about Linux

Linux is one of the most widely used operating systems among system administrators, and even modern application and server development is heavily reliant on the Linux platform.

The Linux Administration Cookbook is your go-to guide to get started on your Linux journey. It will help you understand what that strange little server is doing in the corner of your office, what the mysterious virtual machine languishing in Azure is crunching through, what that circuit-board-like thing is doing under your office TV, and why the LEDs on it are blinking rapidly.

The GNOME 3 desktop environment was officially released in 2011, and in 2020 we are still on version 3.x. Yeah, despite many massive changes over the last (almost) decade, we have been stuck with point releases for GNOME 3. For instance, just yesterday, GNOME 3.38 was released. Historically, the stable releases all ended in even numbers, with pre-release versions ending odd. For fans of the DE, such as yours truly, we have simply learned to live with this odd versioning scheme.

Well, folks, with the next version of GNOME, the developers have finally decided to move on from version 3.x. You are probably thinking the new version will be 4.0, but you'd be very wrong. Actually, following GNOME 3.38 will be GNOME 40. Wait, what? Yes, the developers are actually moving from 3.x to 40.x! They are even ditching the even/odd aspect, as the next major stable version to come after 40 will be 41. Minor stable updates will be given incremental point designations (.1, .2, .3, etc.). During development, there will just be alpha, beta, and release candidates -- nice and simple. Understandably, this is going to be confusing for some Linux users that are used to the old versioning scheme.

One of the best things about Linux-based desktop operating systems is having access to many wonderful desktop environments. While there are many great user interfaces available, only one can be the best. For many years now, GNOME has been the greatest DE, and that is still true today. What makes it so wonderful? Well, GNOME 3.x is ideal for productivity, allowing the user to focus on the task at hand. Not to mention, it is beautiful and simple -- it provides a no-nonsense computing experience. There's a reason both Ubuntu and Fedora use GNOME as their default environment.

Today, the best Linux desktop environment gets even better. You see, GNOME 3.38 "Orbis" is finally here, and it is chock-full of improvements. For instance, the default web browser, called "Web," now has improved privacy settings, including cross-site tracking. There is also a new app called "Tour" which introduces the user to GNOME features after installation. Retro gamers will be thrilled to learn that Nintendo 64 support has been added to the "Games" app. Orbis also provides support for varying refresh rates when using multiple monitors. Best of all, the developers have killed the "Frequent" and "All apps" views, replacing it with a single customizable grid with the ability to drag to reorder the icons.

Hackers are increasingly turning their attention to attacking Linux servers and workstations, according to security researchers from Kaspersky.

While it is Windows systems that have traditionally been in the cross-hairs of attackers, advanced persistent threats (APTs) are now a serious issue in the Linux world. Linux systems are being specifically targeted with an ever-widening selection of malware tools.

Manjaro is one of the most popular Linux-based operating systems these days, and it isn't hard to see why. It is based on the rock-solid Arch, but unlike that distro, Manjaro is very easy to install and use. In other words, it has all the benefits of Arch, but without the hassles and headaches. This makes it a great choice for both Linux experts and beginners.

Manjaro 20 "Lysia" was released back in April, and it was very well received by the Linux community. Today, the first point update, Manjaro 20.1 "Mikah," becomes available for download with a trio of desktop environment options -- Xfce (4.14), GNOME (3.36), and KDE Plasma (5.19). All three DEs are excellent, but Xfce is what the developers consider the "flagship." The Xfce variant comes with an all-new theme called "Matcha." All versions of Manjaro 20.1 come with Linux kernel 5.8, Pamac 9.5.9, and ZFS installation support.

Back in April, we told you about the deepin 20 Beta. That Linux distribution is very special because of just how beautiful it is. No, the operating system is not only about appearance (it is excellent overall), but it shows that Linux can be just as pretty as macOS and Windows 10. Hell, it is arguably more attractive than Microsoft's and Apple's desktop operating systems.

And now, the stable version of deepin 20 is finally here! This version of the operating system is based on Debian 10.5 and is loaded with new features and bug fixes. For instance, it has enhanced biometric support, allowing you to use your fingerprint -- a fairly rare thing in the Linux world. The new installer should be easier than ever, and if you have an NVIDIA GPU, you can opt to install closed-source drivers. Best of all, the app manager is simplified further, improving the discovery and installation of apps.

Dev Channel Insiders are in for a treat this week. Windows 10 Build 20211 introduces a number of new features, including adding Search to the Default Apps pages in Settings.

There’s a big new change for users of Windows Subsystem for Linux (WSL 2) too -- you can now attach and mount a physical disk inside of a WSL 2 distro.

So, here we are in September, six months removed from the release of Zorin OS 15.2. A lot has happened since March -- a pandemic, civil unrest, and out-of-control wildfires are just a few of the things that have made this year quite stressful. Not all is bad, however, as we have football starting up this week -- a great distraction to life's stresses.

Today we also get some big news on the Linux front --  Zorin OS 15.3 is finally here. True, it is just a point release, but once again, it should be the best version of Zorin yet. While great for Linux experts, I highly recommend it to those looking to switch from the buggy and much-maligned Windows 10. Zorin OS is a stable and well-designed operating system that is reminiscent of Windows. And so, its familiarity is a great way for Windows users to comfortably experience Linux. Version 15.3 comes with LibreOffice 6.4.6, which is a great alternative to Microsoft Office.

It's a little over a month since Linus Torvalds announced the release of version 5.8 of the Linux kernel -- something he previously described as "one of our biggest releases of all time".

But despite the fact that Linux kernel 5.8 was released so recently, VirtualBox has already been updated to include support for it. This means that the virtualization software can be used to run distros like Ubuntu 20.10 (Groovy Gorilla), which is powered by version 5.8 of the kernel. The software can also run under distros based on the newest kernel.

There are many Linux distributions nowadays, but sometimes it feels like Ubuntu gets all the attention. Don't get me wrong, Ubuntu is worthy of its praise -- it is a great operating system. Still, why can't other distros shine sometimes? Companies that sell Linux-based computers, like Dell and System76, offer Ubuntu on their Linux computers, but what about Fedora?

Well, if you are a big Fedora fan like me, I have some seriously amazing news. Popular computer-maker Lenovo has started selling a Fedora variant of its ThinkPad X1 Carbon Gen 8 laptop (Windows 10 is an option too). The 14-inch notebook is thin, light, and gorgeous. A ThinkPad running Fedora? It looks like Christmas came early this year...

The popular Ubuntu Linux gets two new versions a year, with one coming in April, and the other in October. Its version numbering scheme is based on year (YY), a period, and the month (MM). For instance, the most recent stable version was released this past April and it is numbered as 20.04. In addition, Canonical (the operating system's owner) assigns names -- sequentially and alphabetically. The alphanumeric code name is always based on two words starting with the same sequential letter -- an adjective followed by an animal name. The aforementioned 20.04 is named "Focal Fossa."

Obviously, the next version of Ubuntu will be numbered 20.10, and it will be given a two-word code name based on the letter "G." This time, the operating system will be called "Groovy Gorilla." Thankfully, development of the operating system seems to be on schedule, as it recently received a feature freeze. What does this mean? Essentially, moving forward, Ubuntu 20.10 should only receive bug fixes -- no more features will be introduced unless by exception. It also signals that the upcoming Beta release should be released on schedule as expected.

Linux owns the smartphone market thanks to Android. While some think Apple's iOS is superior, and maybe it is, that is merely opinion. The fact is, Android has a much larger market share -- it is undeniably more popular. And yet, some Linux enthusiasts are not satisfied with that. Some of these people feel Android is not "true" Linux, but that is just stupidity. The truth is, Android uses the open source kernel, so it is Linux -- end of discussion.

But OK, if you are a Linux fan but an Android detractor, there are some other options, such as the Purism Librem 5 and Pine64 PinePhone. Speaking of the latter, that phone is offered in "Community Edition" variants, and very soon, there will be an official Manjaro version! Yes, you will be able to buy a PinePhone with Manjaro Linux pre-installed on it. There are two variants -- one has 2GB RAM and 16GB of storage for $149, and the other has 3GB memory and double the storage for only $50 more. Other specs can be found here.

Some people think you need expensive hardware to have fun playing video games, but the truth is, you don't. Believe it or not, there are plenty of free games that can run well on a fairly meager PC. No, I am not just talking about emulating classic video games (piracy is bad, mmkay). Actually, there are some really fun PC games that you can legally download at no charge.

One such popular game is SuperTuxKart. This open source Mario Kart clone is totally FREE on Windows, Mac, and Linux. It can even be had on Android too. Rather than use Nintendo mascots, the racers in SuperTuxKart are based on open source projects -- it is quite cute. The game even has network support these days, so you can have a multiplayer experience over the internet. SuperTuxKart recently reached version 1.2, and the new version is chock full of improvements. The developers are also sharing their plans for the future of the game.

The cloud is taking over the IT industry. Any organization housing a large amount of data or a large infrastructure has started moving cloud-ward -- and AWS rules the roost when it comes to cloud service providers, with its closest competitor having less than half of its market share. This highlights the importance of security on the cloud, especially on AWS. While a lot has been said (and written) about how cloud environments can be secured, performing external security assessments in the form of pentests on AWS is still seen as a dark art.

Hands-On AWS Penetration Testing with Kali Linux aims to help pentesters as well as seasoned system administrators with a hands-on approach to pentesting the various cloud services provided by Amazon through AWS using Kali Linux. To make things easier for novice pentesters, the book focuses on building a practice lab and refining penetration testing with Kali Linux on the cloud.
