JVM Internals
When I first started coding Java, I treated the JVM like a magic box. Write code, hit run, and somehow it works on Windows, Mac, and Linux. But once I star…
Testing
I used to hate writing tests. I thought it was a waste of time until I had to refactor a legacy module with 100% coupling. I broke everything, and I spent…
