Overtime, Git has grown to be used by millions of projects today. This course gives you the opportunity to learn how to use git efficiently and make contributions in a relatively short amount of time. It will cover: How to install git How to initialize a repository How to make changes in a repository How to make changes in repositories available to others How to acquire changes made by other individuals How to find errors in your work and go back to earlier states of yoru projects How to make commits, diffs, merges, rebases. The course will help you get the skills to have a good understanding on how to use git. You will have a good knowledge about git workflows, identifying problems in your workflows, and finding solutions to solve these problems.

The course includes fundamental architecture topics that are key to understanding how any Cortex-M processor functions internally. The course focuses specifically on the Armv8-M version of the Arm Architecture, which processors like the Cortex-M33 and Cortex-M55 are based on. However, even if you're working with older processors based on earlier versions of the architecture, like Armv6-M or Armv7-M, a lot of the information is mostly still very relevant and useful.

By the end of this project, you’ll be able to create system and application icons with Inkscape. Inkscape is a free and open-source program that creates vector graphics. Because they’re vector based, images created in Inkscape are ideal for creating icons. They can be resized and edited quickly—and they’ll stay clear and sharp even after the changes. During this project, you’ll practice creating line-based icons and solid-fill icons. You’ll practice researching icon requirements, you’ll prepare the Inkscape workspace to create icons, and you’ll create two different icons: a line-art lightbulb and a solid-fill envelope. Then you’ll practice resizing and exporting those images to meet Apple and Android specifications. By the end of the project, you’ll be comfortable planning and creating icons for iOS, Android, and other systems. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

In this project, learners will know how to publish an app from Visual Studio and then test the app using the Azure DevTest labs service. The app we will create and test will be a console app. We will use some of the services that are available in Azure to create a file share and then test the app. In Azure, the app will be tested using DevTest labs. DevTest Labs is a service that gives functionality for managing environments that contain Azure Virtual Machines. We will also create a file share and virtual machine that will be added to the lab we created in Azure. We will then use Visual Studio to publish the app to the file share that we created in Azure. By the end of the project, you will have learned how to create and test an application using Visual Studio and DevTest labs in Azure.

In this project you will implement a program using C that demonstrates the basic data types and how to input and output them.
