The below article describes the solution architecture we created for risk detection that provides results in real-time and at scale. Together with ksqlDB, features in the Kafka Streams framework help engineers focus on delivering real business value.
The author explores JavaScript’s proposed private class fields, focusing on the unconventional # syntax and its implications. He questions whether this new hard-privacy approach complicates the language more than it benefits developers.
In this article, we explain how to implement a Language Server Protocol server to decouple code presentation from language logic, using Metals and Scala. It walks through adding a simple document highlight feature. 
Kotlin lacks Java’s package-private visibility, exposing everything by default unless explicitly marked, which can bloat APIs and hinder encapsulation. The author praises Java’s manifest-based modular exports for making visibility decisions more conscious and centralized.
VirtusLab compares object‑oriented and functional programming through the Expression Problem, showing how each paradigm handles extensibility differently. The article highlights how FP easily adds new operations, while OOP easily adds new data forms.
