In this meetup talk, I dive into what it means to have a testable architecture. I cover the fundamental point of testable code: separating I/O concerns from domain logic. I compare and contrast architectural patterns such as hexagonal architecture (aka ports & adapters), clean architecture, onion architecture, and others. I show you precisely how to use Test Doubles (stubs, fakes, mocks, etc.) to make testing easier, without the complexities of "mocking" libraries. Once you learn the rules around I/O-Free vs. I/O-Based tests, you'll never wonder "should I be using a Test Double here". 00:00 Introduction to Ted M.

One of the most important, yet misunderstood, aspects of Hexagonal, Clean, and Onion architectures is not their folder structure, but how they keep I/O and domain logic sep

Originally presented at the Live Sound Summit 2018 Michael Krieg dives deep into the physics that make line arrays work, and honestly? This is the kind of presentation that changes how you think about what's happening when you hang a box. Michael doesn't just show you pretty pictures - he breaks down phase relationships, wavelength behavior, and why arrays actually couple the way they do. **What You'll Learn:** - How phase and wavelength determine array behavior at different frequencies - Why line arrays work (the actual physics, not marketing speak) - Coupling vs. non-coupling frequencies and what that means for coverage - Phase alignment between elements and why it matters - The relationship between array length and frequency response - Practical implications for rigging and aiming decisions **About Michael Krieg:** Michael is VP of Education and Application Support at Danley Sound Labs and a veteran of live sound education. He's...
