Linux is an incredibly powerful system with GUI and command-line tools to meet nearly any need. Once upon a time, managing running systems was a bit more challenging on the open-source operating systems because the previous init system required administrators to use a hodgepodge of methods and tools to start, stop, run, and monitor services. With the advent of systemd, that all changed such that admins had a much easier means of controlling the multitude of services their applications and services depend on.

Mozilla Firefox is the default web browser on many, if not most, Linux distributions. Firefox is also the largest and most well-known free and open-source web browser in the world. This may give the impression that Firefox would feel absolutely at home on the Linux desktop.

Functionally, Firefox works just fine on Linux. It's in the appearance department where inconsistencies start to show. Firefox feels ever-so-slightly out of place on most Linux desktop environments, but with a few tweaks, you can make the browser feel more like a native app.

If you're looking for a way to better organize your Firefox bookmarks, the built-in tagging system might be a big help. Learn how to take advantage of this feature.

You’d like to be able to browse the web with some measure of privacy. That’s not an easy task with the major browsers. Instead, you can turn to a lesser known but more privacy-minded browser, and one candidate is the Ghostery Dawn browser.

Made by the people behind the Ghostery browser privacy extension, Dawn tries to limit the information that is typically monitored and recorded when you use one of the major browsers. Toward that end, Dawn offers ad blocking, anti-tracking and an ad-free search engine. Ghostery Dawn is available for Windows, macOS, Linux, iOS and Android.

The Ghostery browser offers free access and paid plans. With free access, you will see private sponsored links in the search results, which the company said helps it pay the bills while still preserving your privacy. To bypass the sponsored links and unlock other products and features, a paid subscription will run you $4.99 a month billed monthly or $3.99 a month billed annually.

Microblogging is a wonderful way to express your thoughts. It is short, succinct and sweet. In this regard, Twitter has been one of the most popular microblogging platforms in the world. However, relying on this particular company for your microblogging needs not be the best solution for everyone.

Fortunately, there are alternatives such as Pleroma which is a self-hosted Twitter. This is a lightweight federated microblogging platform. Using federation allows the platform to communicate with other federated instances which means that you do not need to gather a lot of people for your own private Twitter to start sharing information. This article aims to help you get started with Pleroma.

Any code submission to LibreOffice should pass Gerrit code review in order to get merged into the LibreOffice codebase. This is possible using the code review tool Gerrit.

For Linux users want to configure the boot menu screen, Grub Customizer is always a good choice for beginners.

I’ve written quite a few tutorials about the default boot-loader, which is called Grub, including set default OS to boot, install themes, add kernel parameters for hibernate, custom screen resolution, etc. All of them can be done via Grub-Customizer besides editing the configuration file.

Vim is a powerful text editor, and is also referred to as a modal text editor.

What does "modal text editor" mean? It means that Vim is a text editor that has a mode-based workflow. Each keystroke is paired to a command in Vim. This is in contrast to other editors where each keystroke is registered as text and is written to a text file.

So, what are these modes in Vim? Let's have a look at them.

Rsync stands for “remote synchronization”. Rsync is the most robust, versatile and flexible tool to transfer files if compared to other alternatives like SCP. It is a great tool for daily server operations like backup and restore, and general file operations between two or more local and remote machines. In this article, we will show you how to send and download files using rsync.

Configuring tables is an every day task for word processors. Most users likely insert a table via menu or toolbar and size the columns per mouse. This usually wont result in a satisfying precision and the table properties dialog would be the next step. But here the problems begin for real since using a certain width for all columns is not possible unless the “Adapt table width” is checked, which requires to change the “Automatic” alignment on a different tab to something else.

Kerberos is an authentication method that can assign a user a ‘ticket’ after the first sign-on. Once a user has entered a correct password, then they are granted a ‘ticket’ to allow connection again without a password. The key thing to remember is that the ‘ticket’ expires after a certain amount of time.

Kerberos Authentication is a security measure that adds a level of security between two network systems. Once granted, the two systems ‘trust’ each other.

In this tutorial, we will show you how to install Java on Rocky Linux 8. For those of you who didn’t know, Java is a high-level programming language designed to be portable and to have as few dependencies as possible to run on any system. The general purpose of the Java programming language is to let developers write programs or applications once, but the application itself can be run on any system across multiple operating systems. Java has been around since 1995. It was released by Sun Microsystems as a programming language for “smart” consumer devices, particularly those with multimedia capabilities.

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 the step-by-step installation of Java on Rocky Linux. 8.

In this video, we are looking at how to install Flightgear on Debian 11.

Most Arch Linux installers including the primary iso require an internet connection to complete the installation process but what if you don't have one well you're in luck because Arch Boot exists.

Today we are looking at how to install PreMID and Discord 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.

When web proxies originally came to being, people added support for them in the least invasive and most terrible way possible: using environment variables. Enter http_proxy, https_proxy and their kind. Then the whole Internet security thing happened and people realised that this was far too a convenient way to steal all your traffic. So programs stopped using those envvars.

Oh, I'm sorry, that's not how it went at all.

Some programs stopped using those envvars whereas other did not. New programs were written and they, too, either used those envvars or didn't, basically at random. Those that eschewed envvars had a problem because proxy support is important, so they did the expected thing: everyone and their dog invented their own way of specifying a proxy. Maybe they created a configuration file, maybe they hid the option somewhere deep in the guts of their GUI configuration menus. Maybe they added their own envvars. Who's to say what is the correct way?

This was, obviously, seen as a bad state of things so modern distros have a centralised proxy setting in their GUI configurator and now everyone uses that.

Trololololololooooo! Of course they don't. I mean, some do, others don't. There is no logic which do or don't. For example you might thing that GUI apps would obey the GUI option whereas command line programs would not but in reality it's a complete crapshoot. There is no way to tell. There does not even seem to be any consensus on what the value of said option string should be (as we shall see later).

Since things were not broken enough already, the same thing happened with SSL certificates. Many popular applications will not use the system's cert store at all. Instead they prefer to provide their own artisanal hand-crafted certificates because the ones provided by the operating system have cooties. The official reason is probably "security" because as we all know if someone has taken over your computer to the extent that they can insert malicious security certificates into root-controlled locations, sticking to your own hand-curated certificate set is enough to counter any other attacks they could possibly do.

Because all Librem computers share are built on base OS/PureOS, there are many crossovers when it comes to software. Here is the guide you can use for all Librem Computers.
