This session covers new and upcoming Java features for working with immutable data, and explains how they improve reliability and performance while enabling JVM optimizations and guiding when to use them.

Six years after first comparing Java and Go microservices, the authors revisit the performance question: whether carefully implemented Java and Go HTTP services still deliver similar results on modern runtimes and hardware. Rather than framing it as a language competition, the 2026 article examines how each performs as payload sizes and concurrency increase, with all code, be...

Learn how agentic coding transforms Java migrations by acting as an intelligent development partner.

What are GC barriers and how do they relate to ahead-of-time compilation? This blog post explores the intersection of HotSpot's GCs and compilers through the lense of implementing GC-agnostic load barriers at the assembly level, and gives key insights on performance and overall takeaways.

this article shows an approach to extend the HAT programming model with an API for explicit tensor-core programming. Furthermore, it shows how to make this approach generic to be able to process computations expressed with the proposed HAT tensor core API on accelerators without explicit tensor instructions.
