About This Site | Elixir - Wyatt's Notes

Wyatt’s Notes delivers comprehensive study materials for Elixir programming. These notes cover Elixir’s concurrency model, Phoenix framework, OTP principles, and functional programming patterns, building the skills needed for scalable, fault-tolerant applications.

These notes are created by Wyatt, an educator and content developer with expertise in Elixir and distributed systems. Content follows a structured progression from language fundamentals through OTP to practical Phoenix web development.

Materials emphasise Elixir’s actor-based concurrency, fault tolerance through supervision trees, and the functional programming patterns that make Elixir expressive. Every concept includes practical examples and explains the distributed systems principles behind Elixir’s design.

• Language fundamentals covering syntax, pattern matching, and pipes
• Concurrency with processes, GenServers, and OTP
• Phoenix framework covering channels, live views, and Ecto
• Fault tolerance with supervisors and the let-it-crash philosophy
• Distribution across nodes and clusters

Wyatt develops resources across Elixir, distributed systems, and programming, providing the infrastructure perspective that enhances Elixir materials. Content is informed by Elixir specification, OTP documentation, and production system analysis.

• Haskell — Haskell programming resources
• Go — Go programming notes
• Programming — Multi-language programming resources

Start with the language fundamentals to build a solid Elixir foundation. Each topic progresses from syntax to distributed system patterns. Use the practice problems to develop your concurrent programming skills.

Visit wyattsnotes.wyattau.com for the full network of study resources.

This site provides comprehensive study materials covering:

• Functional programming
• OTP
• Concurrency
• Phoenix

Each topic includes detailed explanations, worked examples, and practice problems designed to build deep understanding.

1. Start with fundamentals — begin with the core topics before moving to advanced material
2. Work through examples — every concept includes worked examples with step-by-step solutions
3. Test yourself — use the practice problems and diagnostic tests to identify knowledge gaps
4. Cross-reference — related topics on other sites in the Wyatt’s Notes network provide additional perspectives

• Flashcards — spaced repetition flashcards for key concepts and formulas
• Practice Problems — graded problems from basic to advanced
• Diagnostic Tests — identify your strengths and weaknesses
• Worked Examples — step-by-step solutions to common problems

These notes are informed by standard university textbooks including Programming Elixir. While the notes follow the general structure of these texts, they are not a substitute for reading the primary sources.

This topic covers the fundamental principles and applications in depth. Each concept is explained with clear definitions, worked examples, and practice problems to reinforce understanding.

Understanding these core concepts is essential for mastering this topic. They form the foundation for more advanced study and are frequently examined.

Worked examples demonstrate how to apply the concepts to solve problems. Each example is broken down into clear steps with explanations.

• Rushing through foundational material
• Not practising problems after reading
• Failing to connect concepts across topics
