We have come a long way since the introduction of Servlets back in 1999. Back then, implementing and getting to run a Servlet required a lot of development, class overloading, XML configuration and a host of other tasks. It prompted improvements like Java Servlet pages and the subsequent move towards frameworks like the model-view-controller model with Struts that have evolved from framework to framework to where we are today, with powerful frameworks like Spring Boot, Micronaut et al. But the Servlet component has not remained idle through those times.

In our wonderful profession of software engineering, the demand for predictable high-performing teams is growing. To bridge this gap, organizations are constantly trying new methodologies and practices. One such practice that has gained momentum is Developer Productivity Engineering. In this blog, I’ll dive into the world of Developer Productivity Engineering, exploring its principles and how it can empower teams.

You never touched Groovy, nor did you jump on the Scala train. Clojure never attracted you; and you heard about Ceylon long after the language had already died. You are one of those old-fashioned Java folks! But now, after all those years, you want to join the cool Kotlin kids. So, where to start? Let’s discover the language together by decompiling it to Java code. Today: Inline functions!
