ABOUT THE AUTHOR ANDERSON SILVA GREW UP IN BRAZIL, and wrote his first program at ANDERSON SILVA the age of 10 using Logo. He moved on to programming in BASIC shortly thereafter, and by the time he was in High School he was coding in Pascal. When he started college in the US, he learned C, C++, Java and had several developer jobs programming with server-side languages for web development like: Coldfusion, Perl, Php, etc. He was introduced to Linux by his uncle back in 1996. In the early 2000s Anderson transitioned from being a developer to more of a system administrator/release engineer. In 2007, one of his professional goals was achieved when he joined Red Hat as a Release Engineer in IT. Since then he has worked in several roles at Red Hat in both IT Operations, Engineering and Infosec. He has an RHCE and RHCA and is an active Fedora package maintainer.

CC BY-SA 4.0 . OPENSOURCE.COM . WHICH RASPBERRY PI SHOULD YOU CHOOSE? Which Raspberry Pi should you choose? In the first chapter in our guide on getting started with Raspberry Pi, learn the three criteria for choosing the right model for you. CHAPTER in a guide THIS IS THE FIRST on getting started with the Raspberry Pi [1]. Although the guide is geared towards people who have never used a Raspberry Pi or Li- nux or programming, there will definitely be things for more experienced readers—and I encourage those readers to leave comments and tips that build on what I write. If every- one contributes, we can make this guide even more useful for beginners, other experienced readers, and even me! So, you want to give the Raspberry Pi a shot, but you don’t know which model to buy. Maybe you want one for your classroom or your kid, but there are so many options, and you aren’t sure which one is right for you. need a USB hub for your mouse and keyboard, possibly a wireless adapter, and some sort of display adapter. Un- Raspberry Pi boards—https://www.raspberrypi.org/products/ less you have most (if not all) of the peripherals needed for whatever you want to do with your Raspberry Pi, make sure to add those to your Pi budget. Also, in some countries, a Raspberry Pi on its own (even without any peripherals) may be a cost burden for many students and teachers. • Availability: Finding the Raspberry Pi you want can vary depending on your location, as it may be easier (or harder) to get certain versions in some countries. Availability is an even bigger issue after new models are released, and it can take a few days or even weeks for new versions to become available in your market. • Purpose: Location and cost may not affect everyone, but every buyer must consider why they want a Raspberry Pi. The eight different models vary in RAM, CPU core, CPU speed, physical size, network connectivity, peripheral ex- pansion, etc. For example, if you want the most robust solution with more “horsepower,” you probably will want the Raspberry Pi 3 B+, which has the most RAM, fastest CPU, and largest number of cores. If you want something that won’t require network connectivity, won’t be used for CPU-intensive work, and can be hidden in a small space, you could go with a Raspberry Pi Zero. Wikipedia’s Raspberry Pi specs chart [2] is an easy way to compare the eight Raspberry Pis models. My three main criteria for choosing a new Raspberry Pi are: Now that you know what to look for in a Raspberry Pi, in • Cost: Don’t just consider the cost of the Raspberry Pi board, the next chapter, I will explain how to buy one. but also factor the peripherals you will need in order to use it. In the US, the Raspberry Pi’s cost varies from $5 (for the Links Raspberry Pi Zero) to $35 (for the Raspberry Pi 3 B and [1] https://www.raspberrypi.org/ 3 B+). However, if you pick the Zero you will probably also [2] https://en.wikipedia.org/wiki/Raspberry_Pi#Specifications . RASPBERRY PI: HOW TO GET STARTED . CC BY-SA 4.0 .

  • Python Intro #1
    Python Intro #1 Python is a popular programming language. It was created by Guido van Rossum, and released in 1991. It is used for: • web development (server-side), • software development, • mathematics, • system scripting. What can Python do? • Python can be used on a server to create web applications. • Python can be used alongside software to create workflows. • Python can connect to database systems. It can also read and modify files. • Python can be used to handle big data and perform complex mathematics. • Python can be used for rapid prototyping, or for production-ready software development. Why Python? • Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc). • Python has a simple syntax similar to the English language. • Python has syntax that allows developers to write programs with fewer lines than some other programming languages. • Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick. • Python can be treated in a procedural way, an object-orientated way or a functional way. Good to know • The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, although not being updated with anything other than security updates, is still quite popular. • In this tutorial Python will be written in a text editor. It is possible to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing larger collections of Python files. • Python Syntax compared to other programming languages • Python was designed for readability, and has some similarities to the English language with influence from mathematics.

  • Bachelor Thesis of Liu (2017) [18]
    Abstract of Thesis Zusammenfassung der Arbeit Abstract of Thesis Fachbereich: Electrical Engineering and Computer Science Department: : Studiengang: Information Technology University course: : Thema: Raspberry Pi Programming with Windows IoT using C# and Subject: Xamarin.Forms – Hardware connections with I²C Zusammenfassung: Abstract: The aim of this thesis is to investigate the possibilities and limitations of Raspberry Pi programming with Windows IoT operating system and Xamarin.Forms – a cross-platform development toolkit in C#. The thesis was conducted in May 2018 at Fachhochschule Lübeck. This topic is of interest because the Raspberry Pi, Windows IoT and Xamarin.Forms are new technologies for software development. This study did several programming experiments. These programs were connected to I²C devices to fulfil their tasks such as run time comparison to Python, converting Windows Forms applications to Xamarin.Forms applications, automation control program for temperature and balance, and remote control with Android smartphone. In addition, some C# external libraries like “Microcharts” for chart display and “MicroTimer” for high-performance timer were also investigated and used in the programs. The results show that Raspberry Pi with Windows IoT is capable of performing the automation control as expected, the “Microcharts” and “MicroTimer” can be easily implemented by Xamarin.Forms. Furthermore, the conversion of the old C# applications as well as the cross- platform programming in Xamarin.Forms is considerably convenient. Despite of its limitation of compatibility problems and lack of UI elements, the Xamarin.Forms with Raspberry Pi and Windows IoT has shown their potential and they may be a suitable platform for software development. This thesis may be useful in providing an alternative way of Raspberry Pi programming and cross-platform application development.

  • Iostick Version 2021 SII/Abitur
    IoStick Version 2021 SII/Abitur IoStick ist eine Sammlung von Programmen für den Informatikunterricht in der Schule. In Analogie zu den PortableApps sind alle Programme direkt vom USB-Stick lauffähig, eine Installation ist nicht mehr erforderlich. Dies gilt insbesondere für das Java Development Kit, das direkt auf dem IoStick installiert ist und von Java-Entwicklungsumgebungen genutzt werden kann. Neu in der Version 2021 Mit der Version 2021 wurde die Software – wenn verfügbar – auf 64 Bit umgestellt. In der Regel sind die Betriebssystemversionen von Windows 10 im schulischen Einsatz auch 64bittig. Sollte das Betriebssystem dies nicht unterstützen, so muss auf den IoStick 2020 ausgewichen werden. Außerdem ist nun die Installation in tieferliegende Ordnerstrukturen möglich. Installation/Einrichtung des Sticks Alle Dateien müssen unter Beibehaltung der Ordnerstruktur in ein Verzeichnis eines beschreibbaren Datenträgers entpackt werden. Dieser Vorgang kann in Abhängigkeit von der Geschwindigkeit des USB-Sticks zwischen 30 und 300 Minuten in Anspruch nehmen! Der Stick benötigt auf dem Datenträger einen Speicherplatz von ca. 2,2 GByte. Start und Startmenü des Sticks Das Startmenü des Sticks wird durch das Programm PStart geladen und im Systembereich neben der Uhr angezeigt. Außerdem wird das Tools Cafe gestartet. Dieses sorgt für die Assoziation von Dateitypen mit den Applikationen auf dem IoStick. Die Konfiguration erfolgt in der zugehörigen INI-Datei. Auswerfen des Sticks Das sichere Abmelden des Sticks sollte stets mit dem PStart-Menüeintrag „USB-Stick sicher auswerfen“ erfolgen. Damit werden alle ggf. noch geöffneten Dateien des Sticks geschlossen. Anpassung/Erweiterung/Reduzierungen des Sticks Für Erweiterungen sind die vorgefertigten Pakete von PortableApps besonders geeignet. Sie müssen nur in den Ordner IoStick installiert werden.
