How to set desktop background in minimal environments
Graphical environments on Linux can basically be divided in two main groups: full-featured desktop environments such as GNOME, KDE Plasma or XFCE, and barebone, minimalistic window managers, such as i3, openbox, or sway. The former come with a set of applications and utilities designed to work well together, while the latter are meant to perform just one task (or little more): managing windows. When using those environments additional functionalities must be implemented via separate tools.
How to deploy a self-hosted Vaultwarden instance
Everyone, nowadays, has several accounts and credentials to take care of, that’s why everyone needs a decent and possibly open source password manager.

In this article we explore an alternative which can be the ideal solution for individuals and small organizations: Vaultwarden.
How to create encrypted git repositories with git-remote-gcrypt
Git is, by far, the most used version control system. Being it “distributed”, means that each user can clone its own full copy of a repository on which he can work even if offline, pushing changes to a remote only when ready. Git repositories are not designed to host sensitive information, but in certain situations, the ability of transparently encrypt the content of a repository can come in handy. The git remote-gcrypt helper is designed with this goal in mind.
How to customize Firefox using policies
In a world where Google Chrome is, by a large margin, the most used web browser, Firefox represents the only relevant open source alternative. The Mozilla browser is installed by default (or at least available in the official repositories) of all the most used Linux distributions. In order to configure its behavior we can change settings interactively, or, more conveniently, we can create and deploy “policies”.
How to mount a remote filesystem over SSH with sshfs
SSH (Secure Shell) is a protocol used to establish an encrypted connection with a remote machine using a client-server model: the ssh server runs on the machine we want to access remotely, while a client is used on the machines from which we want to connect. Thanks to sshfs, we can use an existing SSH connection to mount a remote directory in a secure way, without using additional services like NFS or Samba.
How to manage power profiles over D-Bus with power-profiles-daemon on Linux

OpenLiteSpeed vs Nginx
One of the first – and most crucial – decisions that a website owner will need to make is what type of web server to use. The decision to host your website on a Linux system is a no brainer, but when it comes to web servers, there are a few choices and they all come with their own pros and cons. Among the most popular on Linux is NGINX and OpenLiteSpeed, both well known for their speed and ability to host concurrent connections.
FreeBSD vs GNU/Linux: What’s the difference
Every person in the tech industry or those that have spent some time tinkering with computers has heard of GNU/Linux. When it comes to FreeBSD, far less people are aware of its existence and not a lot of users (or even system administrators) understand the difference between the two operating systems. The most likely scenario of how you wound up here is that you have used Linux for a while, and are now wondering if FreeBSD is better or if it is a good idea to switch.
