What new technology or tool has recently interested you and why?

Recently, I became interested in the GraalVM project — a universal virtual machine that supports multiple programming languages and allows running Java applications with improved performance and reduced startup time. The ability to compile Java applications into native images, which significantly shortens startup time and memory consumption, is particularly interesting.

This is relevant for microservices architecture and cloud solutions, where deployment speed and resource efficiency are crucial. Additionally, GraalVM supports integration with JavaScript, Python, and other languages, expanding the possibilities for inter-language interaction.
