How to check GPIO status
The GPIO (General Purpose Input/Output) pins of the Raspberry Pi are how the device can interface with external hardware components. It is how things like sensors and actuators plug into the Raspberry Pi, and allow users to control such devices from the Raspberry Pi itself. Something as simple as turning an LED on or off will require setting the pin to which it is plugged in to either true or false, which changes the current status of that pin.
How to Install Node.js on Ubuntu 24.04
Node.js is a powerful JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows developers to create scalable backend functionality using JavaScript, a language many are familiar with from front-end development. Installing Node.js on your Ubuntu system enables you to develop and run JavaScript applications outside the browser environment. This tutorial will guide you through three methods of installing Node.js on Ubuntu 24.04: using Ubuntu’s package manager (APT), Node Version Manager (NVM), and the official Node.js binary.
StartOS Linux In-Depth Review: A Comprehensive Look at Performance, User Experience, and Compatibility
StartOS (formerly known as EmbassyOS) is a graphical, browser based Linux distribution for servers by Start9.

It is a standard compiler used in most projects related to GNU and Linux, for example, the Linux kernel. The objective of this tutorial is to install GCC, the C compiler, on Ubuntu 22.04 Jammy Jellyfish. Installation of GCC can be achieved by using the apt install command as you will see below.
How to check power consumption on Raspberry Pi
As you can probably guess just from its small size and light weight, the Raspberry Pi does not use a lot of power. While it is nice to know that your Raspberry Pi will not be adding much onto your electric bill, exactly how much power does it actually consume? This can be tricky to answer and we need to rely on external devices, since power consumption can’t be accurately measured from software alone.
How to reset Kali Linux root password
It’s possible to reset Kali Linux password in the event that you are no longer able to login to the root user account. This happens if you haven’t logged in for a while and have since forgot Kali Linux password. In case you have not already tried, the default Kali password for root user is toor (root backwards) on VMWare and live images. Try logging in with this password before resetting the Kali Linux password.
How to change Python versions on Raspberry Pi
It is possible to have multiple versions of Python installed on the Raspberry Pi simultaneously. It is also simple enough to switch between the versions, which may come in handy for Python programmers that need to support a mix of legacy and modern Python code. Or, perhaps you want to try out a new beta or nightly Python build, without replacing the more stable copy you already have. In this tutorial, you will see how to change between various Python versions on the Raspberry Pi.
Ubuntu Server 20.04: Connect to WiFi from command line
In this tutorial, you will learn how to connect to WiFi from command line on Ubuntu using Netplan. While this method can be used on Ubuntu desktop systems with a GUI, it is especially useful if you’re running a headless Ubuntu 20.04 system like a Raspberry Pi or need to connect to Wifi on Ubuntu Server. Follow along with us below as we connect to a WiFi on command line via SSID and network key.
How to use bash array in a shell script
In this tutorial, we will see how to use Bash arrays and perform fundamental operations on them. Bash, the Bourne Again Shell, is the default shell on practically all major Linux distributions: it is really powerful and can also be considered as a programming language, although not as sophisticated or feature-reach as Python or other “proper” languages. Furthermore, Bash scripting is a must-have skill for any Linux system administration job.
