Basics of Sustainable Software Engineering in Julia

Sustainable Software Engineering is an essential aspect of modern software development, focusing on practices that ensure long-term efficiency, maintainability, and scalability of software projects. This introduction covers the core principles of Sustainable Software Engineering, including the use of Git for version control, the importance of testing, the role of documentation, and the specifics of applying these practices in the Julia programming language.

Basic Introduction to Linux Shell

Overview

The Linux Shell is a command-line interface (CLI) used in Linux operating systems. It allows users to interact with the system by typing commands, rather than using a graphical interface.

Accessing the Shell on UNIX (+maxOS)

Terminal: Open the terminal application from your Linux desktop environment.

Accessing the Shell on Windows

Git Bash: Has most of the common tools included.
Other options: PowerShell, WSL, ...

Simplicity: Markdown is easy to learn and use.
Portability: Markdown files are plain text, so they're readable on any device.
Flexibility: You can convert Markdown to HTML, PDF, and more.

Basic Syntax

Headings

Use # for headings. More #s mean smaller headings.
