Most Singletons in production are broken.

After 15 years in development, I still see services crash or slow down because of "clever" implementations that create memory leaks and race conditions. If your JVM memory looks like a mountain range, your Singleton implementation is likely the culprit.

We have a tendency to choose complex code over simple, working solutions—often fueled by "Resume-Driven Development."

In my latest video, I cut through the fluff and look at the reality of technical debt. I cover why Eager Initialization, Lazy Loading, and Double-Checked Locking are usually the wrong choices and focus on the only two methods you should actually use in 2026.

Key Topics:

The Memory Collapse: Why "clever" code instantiates objects on every request.

The Bill Pugh Singleton: Using the Holder Idiom for thread-safe instances.

The Enum Singleton: The gold standard for reflection-proof and serialization-safe code.

Testing Reality: How to properly handle Singletons using DI and interfaces.

Stop adding complexity. Complexity is debt. Fix your code so you can actually enjoy your weekend.
