When to use var in Java?
Keep types explicit unless the generics get out of hand. If you have to hit F1 just to know what a variable returns, the code is harder to read than it needs to be. This is one reason that dynamically typed languages like javascript are hard to read.

Figuring out Embabel's subagent pattern:
```
IntentRouter
└─> EditOrchestrator
├─> NameEditAgent
├─> ColorEditAgent
└─> RouteEditAgent
```
RunSubagent shares context. Each agent is independent & testable. New edit type? Just add a new agent.

Testing used to feel impossibly hard. That struggle was a signal—I was testing at the wrong level or fighting my architecture.
The worst part? Spending more time setting up mocks than testing behavior.

Designing for Testable Code with a Testable Architecture (Calgary Software Crafters Meetup)
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. Young 00:34 The TDD Game and Testable Architecture 02:01 Purpose and Importance of Tests 03:55 Attributes of Effective Tests 09:22 Challenges in Writing Tests 11:18 Separating Logic and I/O for Testability 14:48 Understanding Testable Architecture 34:01 Hexagonal Architecture and Domain-Driven Design 44:06 Practical Example: Testing a Simple Application 53:48 Automating Event Management...

Finally tried pair programming yesterday. Was intimidating - imposter syndrome was loud - but pitched it as an experiment. One hour saved me days of wasted effort. The real-time feedback is powerful. Pre-learning the `mob` CLI helped. If you're hesitant to ask - just do it. Worth it.

AI coding assistants: fireplace when you understand the codebase, house fire when you don't.
The irony? They're most appealing exactly when they're most dangerous.
They give you velocity, not vision. And velocity without vision is just motion toward nowhere.

🧪 Fought Jest + NextAuth mocking for an hour. `ECONNREFUSED` despite `jest.mock()`.
Fix: `jest.resetModules()` + dynamic `require()` in `beforeEach`. Forces fresh module loading so mocks actually work.
Coming from Spring Boot's `@MockUser`, surprised this isn't documented.

Michael Krieg: Line Array Phase, Wavelength & Why Arrays Work | Live Sound Summit 2018
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...

"Just assign it somewhere!" Sure—except now I'm facing 200+ configurations to test through trial and error.
That's when I realized: the value of a product is someone else doing the brain work so you can use it.
