Event-Driven Architecture from a Functional Perspective
Event-driven systems and functional programming are rarely discussed together, yet they fit remarkably well. Immutability, explicit error handling, and pure transformations make event-driven code more predictable, composable, and easier to test. This post explores how functional ideas sharpen the design of event-driven architectures.

Pragmatic Functional Programming vs Academic Purism
Where does the line fall between adopting functional ideas that genuinely improve Java code and chasing theoretical purity that only adds ceremony? A frank look at what FP concepts are worth carrying into production Java, and which ones are better left in the research papers.
