GNU Guix: Documentation video creation

Filed under
GNU
HowTos

Over the last few months, I have been working as an Outreachy intern with the GNU Guix crowd to develop videos presenting and documenting the project. My goal in this round as an Outreachy intern for the December 2018 to March 2019 period consists of creating introductory documentation videos about different topics for people who would like to use GNU Guix, admins and/or those who would like to join Guix community and don’t know where to start. Even interested or having a clear documentation, they might feel overwhelmed by it. I experienced this issue in the past with people in another context.

My main tasks consist of creating a workflow for automating as much as possible the process of creating the videos, as well as, of course, creating the videos themselves. Creating the videos is not that easy as it might seem, I have to design them (I cannot automate that part), let the audio match the video, and matching the exact timing is quite difficult. Something very important that I should mention is that the workflow currently allows translations to other languages.

It is a work in progress for too many reasons, specially because it keeps being improved all the time.

Program the real world using Rust on Raspberry Pi

Linux
HowTos

If you own a Raspberry Pi, chances are you may already have experimented with physical computing—writing code to interact with the real, physical world, like blinking some LEDs or controlling a servo motor. You may also have used GPIO Zero, a Python library that provides a simple interface to GPIO devices from Raspberry Pi with a friendly Python API. GPIO Zero is developed by Opensource.com community moderator Ben Nuttall.

I am working on rust_gpiozero, a port of the awesome GPIO Zero library that uses the Rust programming language. It is still a work in progress, but it already includes some useful components.

Getting started with PiFlash: Booting your Raspberry Pi on Linux

Filed under
Linux
HowTos

Most people install some form of Linux when they set up a Raspberry Pi computer. Until recently, the installation tools for creating a bootable SD card were only available for Windows and MacOS desktops. If you were running Linux on your desktop, you got a page of instructions on doing it manually from the command line.

That works. But if you experiment with multiple Raspberry Pi boards, over time this gets tedious. As an engineer and a coder, I started thinking about automating it to make it easier and, in the usual way open source projects get started, I came away with PiFlash.

Raspberry Pi 3 Model B+ First Impressions

I have always been curious about the tiny computer called Raspberry Pi but I didn’t have the time or opportunity to buy one until now. I got the latest version (Raspberry Pi 3 Model B+) along with bundled accessories from AliExpress for $65. I think it was a good deal considering what I got which I will explain to you later on. But before that and for your convenience, here are some quick facts about Raspberry Pi that I got from Wikipedia... Read more
