Project Valhalla's First Preview: JEP 401 Redefines == for Java Objects

A N M Bazlur Rahman — Mon, 10 Aug 2026 14:32:00 GMT

JEP 401, integrated into JDK 28, introduces value objects. These new class instances feature final fields, altered behavior for equality checks, and stricter construction and synchronization rules. It aims to enhance efficiency and reduce memory allocation costs. However, the preview is disabled by default and requires specific configuration at compile and run time.

Presentation: Automatically Retrofitting JIT Compilers

Laurence Tratt — Wed, 05 Aug 2026 11:00:00 GMT

Laurence Tratt discusses yk, an open-source meta-tracing JIT compiler framework. He shares how to automatically speed up C-based language interpreters like Lua and MicroPython with minimal, non-invasive code changes. He explains the inner workings of tracing loops, optimizing compiled traces using developer hints, and managing complex deoptimization back to the interpreter.

Presentation: The Free-Lunch Guide to Idea Circularity

Holly Cummins — Fri, 31 Jul 2026 11:00:00 GMT

Holly Cummins discusses why "nothing is new under the sun" in tech. She maps historical architectural tradeoffs to modern cloud, microservices, and AI hype cycles. She connects financial debt (post-ZIRP) and technical debt to epistemic and sleep debt, showing engineering leaders how to navigate shifts in assumptions, embrace sustainability, and revive proven engineering disciplines.

Article: Virtual Threads after JDK 24: What Changed for Production Java

Sandeep Bharadwaj — Fri, 31 Jul 2026 09:00:00 GMT

JDK 24 removed the monitor-related carrier-thread pinning that stalled Netflix and similar teams on Java 21. What has replaced it on JDK 25 LTS is downstream-resource saturation: the bottleneck moved and now demands explicit bounding in application code. This article maps the failure modes that surface after virtual-thread adoption and gives a practical sequence backed by a public benchmark.
