Aim: Brief introduction to GitHub and how it can be useful for projects within SDCA

Questions: This is a new topic for many and there can be some GitHub-related lingo. I will try to explain everything as we go along, but if you have questions, don’t hesitate to ask.

Who am I?

  • Primarily working on the Seedcase Project
  • Develop teaching material and teach workshops
  • R-package: Open-Source Diabetes Classifier
  • Admin for steno-aarhus on GitHub
  • Seedcase Project: open source software (Python packages) for packaging and documenting research data

I spend 95 % of my work time using GitHub 🙌

What is GitHub?

  • A website: github.com
  • Stores files in repositories
  • Uses version control (Git) to track file changes
    • Git + Hub

  • Website: At its core, it’s a website. If you open up your browser and type in “GitHub.com”, you will be taken to GitHub
  • Stores files: GitHub is a place where you can store and share files related to a project, like a website, in a “repository” (meaning “storage” or “place to keep things”, in Danish: “opbevare”).
    • A repository is like a folder on your computer, but instead of being on your computer, it’s on the internet. You can access it from anywhere with an internet connection.
  • Central to GitHub is that it uses a version control system called “Git”
    • In Danish: “versionsstyring”
    • Git: Track changes to files and folders over time (who made the changes, when + a message describing the changes)
    • The name “GitHub”: A “hub” (central place) for storing and sharing files, using Git to track changes

What can GitHub be used for?

  • Storing and sharing files (while tracking changes)
  • Creating websites
  • Collaboration
    • Reviews: Giving and receiving feedback
    • Communication (tasks, to-do lists, discussions)
    • Project management (project boards)
  • Store/share files like documents, images, code for your data analyses

Why use GitHub?

  • Everything related to your project in one place (files, tasks, discussions, feedback, project management)
  • Changes are tracked
  • Everything is open and accessible to everyone (unless you make it private)
  • Eases collaboration
  • Everything in one place:
    • Files stored in the same place as your tasks, discussions, feedback, and project management
    • No need to email files around or having multiple versions of the same file
  • Tracking changes: You can see who did what when + revert to previous versions of files if needed
  • Transparency: On GitHub, everything is open and accessible to everyone (unless you make it private). This means that anyone can see your work, and you can see other people’s work.

Examples: GitHub.com 👀

Show:

  • The steno-aarhus organisation

  • Simple example: A website repository (prodiap)

    • Files and folders
    • Version control (commits)
    • Issues

  • Collaborative example: A Seedcase repository

    • Files and folders
    • Issues
    • Pull requests + feedback (find a nice example beforehand)
    • Project board

GitHub Intro workshop, May 26

  • Gentle introduction to using GitHub for managing and working with files
  • Registration: Mail from Louise
  • Pre-workshop tasks

Pre-workshop tasks: Around 1 hour to complete. Mostly reading to build a common foundation for the workshop and get familiar with the concepts we’ll apply during the workshop.
