📚 Open Source Contribution (Day 1)

🔐 1. Generating an SSH Key for GitHub

SSH keys provide a secure way to authenticate with GitHub without repeatedly entering credentials.

Steps to set up an SSH key:

  1. Generate a new key: 
   ssh-keygen -t ed25519 -C "your_email@example.com"
Enter fullscreen mode Exit fullscreen mode
  1. Save in the default location (press Enter).
  2. Start the SSH agent: 
   eval "$(ssh-agent -s)"
Enter fullscreen mode Exit fullscreen mode
  1. Add the key to the agent: 
   ssh-add ~/.ssh/id_ed25519
Enter fullscreen mode Exit fullscreen mode
  1. Copy the public key: 
   cat ~/.ssh/id_ed25519.pub
Enter fullscreen mode Exit fullscreen mode
  1. Add it to GitHub:
    • Go to Settings → SSH and GPG Keys → New SSH Key
    • Paste the key and save.

🌍 2. Open Library – A Digital Book Repository

  • Developed by Internet Archive.
  • Goal: Create a dedicated page for every published book.
  • Open-source – contributions welcome!
  • Website: openlibrary.org

🏛️ 3. Internet Archive – A Digital Knowledge Hub

  • A non-profit digital library.
  • Archives books, music, videos, and websites (via Wayback Machine).
  • Mission: Preserve and provide free access to information.

🌐 4. WorldCat – A Global Library Catalog

  • Connects users to books and media in libraries worldwide.
  • Useful for finding physical copies near you.
  • Visit: worldcat.org

📘 5. Open-Source Contribution: Use First, Contribute Later

  • First, explore and use the project (e.g., read books on Open Library).
  • Then, contribute by fixing errors, improving content, or coding.
  • Common in open-source: Engage with the tool before enhancing it.

🆚 6. Free Software vs. Open Source

Aspect Free Software (e.g., GNU/Linux) Open Source (e.g., Git, Firefox)
Focus User freedom (4 essential freedoms) Collaboration, practicality
Licensing Strong (GPL) Flexible (MIT, Apache, etc.)
Goal Ethical use & sharing Community-driven development

✅ Both allow code access and modification.

🔍 7. Finding Open-Source Projects

  • GitHub search: 
  is:issue is:open label:"good first issue"
Enter fullscreen mode Exit fullscreen mode

🛠️ 8. Anki – Spaced Repetition Flashcards

  • Open-source tool for efficient memorization.
  • Uses spaced repetition algorithms.
  • Download: ankiweb.net

🗂️ 9. Kanban – Visual Task Management

  • Tracks progress in columns: To Do → In Progress → Done.
  • Tools: GitHub Projects, Trello, Notion.

📺 10. NewPipe – A Privacy-Focused YouTube Client

  • No ads, background playback, lightweight.
  • Open-source alternative for Android.

💡 11. Steps to Contribute to Open Source

  1. Find a project (GitHub, "good first issue").
  2. Fork → Clone → Modify → Push → Open PR.
  3. Engage with the community (Slack/Discord, issue discussions).
