Installation

We highly recommend installing the software before the workshop.

1. Julia language

Please go to https://julialang.org/downloads and install Julia v1.11 via juliaup. If you are on Windows, search for "julia" in the app store, it has the same effect.

Launch Julia by clicking on the Julia icon on the menu bar or by typing "julia" in your terminal. Both methods should work.

2. VSCode IDE

Please go to https://code.visualstudio.com and install Visual Studio Code. We will use VSCode to write scripts, inspect results, etc.

3. Julia extension for VSCode

Launch VSCode, and click on the Extensions tab on the left bar (or press Ctrl+Shift+X). Search for "julia" and install the extension.

Start Julia within VSCode to make sure that the extension was installed correctly. You can do that by pressing Alt+J Alt+O.

4. Project files and environment

Download the ZIP archive with all project files by pressing on the green Code button above, and on the Download ZIP button. Unzip the files in a local directory that you can easily find later.

Open the project folder on VSCode, start Julia in the folder, and instantiate the project environment:

# import package manager
import Pkg

# activate current folder
Pkg.activate(".")

# download/precompile packages
Pkg.instantiate()

The instantiation may take a couple of minutes depending on your internet connection and hardware.

Answers

The final script with all answers can be found in the answers branch of this repository.
