Explore fractal architecture principles in software development through this NDC Oslo 2022 conference talk by Mark Seemann. Discover how to improve code readability and productivity by writing code that "fits in your head" at all levels of abstraction. Learn about encapsulation, aggressive thresholds, and referential transparency, with code examples in C# that are accessible to developers working in various languages. Gain insights into the challenges of software development, the importance of reducing time spent reading code, and strategies for creating self-similar code structures. Delve into topics such as the magical number, chunks, long-term and short-term memory, object activation, and pure functions. Conclude with a summary of fractal architecture concepts and a Q&A session.
