Ads can be really annoying on some websites, and while there are browser extensions like Adblock to block them, those solutions are only local to your browser, and not always very effective. A better way to block ads is to use a Pi-Hole on your local network. Pi-Hole is a software for the Raspberry Pi, that acts as your DNS server to block queries for known advertiser domains. Let’s see how to install Pi-Hole on a Raspberry Pi, and how to configure your network to use it!
A quick solution to SD card corruption is to create a backup image of your SD card, so that if you face a SD card corruption again, you can simply burn that image to the card, put it in your Raspberry, and be back exactly where you were before the corruption. In this article we’ll learn how to create an image of the Raspberry Pi’s SD card (or any SD card really) on Mac OS X.
In this tutorial we’ll learn how to install Mosquitto on a Raspberry Pi. The goal is to use the Raspberry Pi as a MQTT broker in an IoT application. We’ll install Mosquitto, configure it and test it to make sure everything was correctly set up.
In some situations, it can be useful to simulate user events on a keyboard or mouse, without an actual keyboard or mouse. The original idea that made me look into this subject, was that I wanted to run RetroPie on my Raspberry Pi with different ways to control the system. Instead of a keyboard, I wanted to use GPIO inputs (buttons or joysticks), or even a web interface that I could access from my phone. We’ll use a program called xdotool to do this.
