Key Takeaways

• Elixir and the Phoenix framework offer a maintainable and explicit approach to building applications.
• Functional programming paradigms can simplify code organization and improve maintainability. Object-oriented programming and functional programming have different approaches to code organization and maintainability.
• The active record pattern in Rails can lead to large and complex models, while the repository pattern in Phoenix provides a more modular and explicit approach.
• Open source contributions can be seen as a good faith contribution to the commons and can provide benefits such as status and marketing opportunities.
• Developers can improve their design skills by studying resources like the book 'Refactoring UI' and being introspective about user interfaces in their daily lives.
