One of the most common ways for users to access and administer their Raspberry Pi is via a VNC connection. VNC allows users to control their Raspberry Pi remotely, and interact with the desktop environment as if they were sitting directly in front of the Raspberry Pi, with a monitor and other peripherals plugged in. In reality, the Raspberry Pi needs nothing more than an Ethernet or Wi-Fi connection to facilitate VNC connections and full access to the system’s desktop.

How to Install Adobe Acrobat Reader on Ubuntu 20.04 Focal Fossa Linux
Since Ubuntu does not have a native way to open PDF documents by default, users will need to install Adobe Acrobat Reader for Linux, or some other program capable of opening the documents. The objective of this tutorial is to install Adobe Acrobat Reader on Ubuntu 20.04 Focal Fossa Linux.
Automating Raspberry Pi: How to Autostart Programs
Getting programs to start up automatically on your Raspberry Pi will help you to automate the device for certain tasks. Most users are likely not going to use their Raspberry Pi as a daily driver, so they will need services and programs to start up automatically without further user intervention. Whenever we can automate such tasks, it makes less work for us. In this tutorial, we will go over the step by step instructions to enable programs to autostart via command line and GUI on a Raspberry Pi.
Easy Steps to Update Your Raspberry Pi
Like all Linux systems, it is necessary to keep your Raspberry Pi up to date in order to make sure that your device has the latest software features and drivers, security patches, and application updates. It is always recommended to keep your Raspberry Pi updated for these reasons, and the process for doing so is very easy. In this tutorial, we will go through the easy step by step instructions to update your Raspberry Pi.
How to install and self host an Ntfy server on Linux
Ntfy is a free and open source notification service written in Go which lets us easily send and receive push notifications on smartphones or desktop computers via simple POST or PUT requests. The basic online service is publicly available free of charge and, on Linux, it is also possible to self-host an Ntfy instance.
How to show software/package installation date
In case you are wondering when a software package was installed on your Linux system, the information is stored by the package manager and can be accessed via the command line. This can come in handy for a number of reasons, such as when troubleshooting issues that started on a certain date, to see if any packages installed at that time could be causing the problem. In this tutorial, you will learn how to show the installation date for a software package on all major Linux distributions.
Kubernetes and Linux: Is It a Good Combo?
When it comes to software deployment and development, Kubernetes has quickly risen in popularity as being one of the best tools for managing containerized applications at scale. The best way to squeeze the most performance and stability out of your Kubernetes cluster is, you guessed it, to run it on top of a Linux system. Linux has a proven track record of decades of stability in running the most demanding applications, and Kubernetes proves to be no exception. In this tutorial, we will look at the ways Linux and Kubernetes make a good combo in running a large cluster of applications at scale.
How to Install Kubernetes on Linux Mint
Linux administrators can build a cluster with Kubernetes and deploy containerized apps inside of it. Kubernetes makes it easy to scale your containerized applications, keep them up to date, and it also provides fault tolerance by distributing the workload across numerous nodes. Installing minikube is one of the simplest methods to begin using Kubernetes.
Linux System Requirements for Kubernetes
Running a Kubernetes cluster can consume an incredible amount of system resources, depending on the size of your cluster, the services you are running, how many replicas are needed for scaling, and what kind of cluster you decide to launch (for example, kubeadm or minikube). Then again, a small cluster may consume next to no resources. Since there is so much variance in Kubernetes clusters, it can be hard to ascertain the system requirements for running one.
How to run JAR file on Linux
JAR files are those that have been coded and compiled using the Java programming language. In order to run these files on a Linux system, the Java Runtime Environment (JRE) software must be installed first. This is just a software package that allows the system to understand JAR files, and therefore gives it the ability to open and run them. Usually, the JRE package is not installed on most Linux distros by default, so we must first install Java, and then we can open the JAR file(s).
How to Check Kubernetes Version on Linux
Checking the installed version of Kubernetes is an important part of system administration, since it will allow you to keep on top of the latest updates and security patches that are released for your software. It is also important to ensure that your various Kubernetes components are updated alongside each other, as much variance in the version number could cause problems.
How to Install kubectl Linux Binary
The kubectl command is an essential part of Kubernetes, and is used to single handedly manage the entire cluster. It provides an interface for administrators to get information about their Kubernetes cluster, and manage the cluster through deploying applications and services, scaling systems, performing updates, and much more. On a Linux system, there are several ways to install the kubectl binary and to keep it up to date.
