JDK 28 FFM allocations will be much faster: Arena.ofConfined() can reuse native-memory pools without source changes while preserving lifetime, confinement, and zero-initialization guarantees. Early microbenchmarks show up to 18x improvements! inside.java/2026/10/05/confi… #java #FFM

The Limitations of Running a Workload Generator In the Same JVM as the System-Under-Test

If you care about tail latency in SPECjbb2015, Composite mode hides GC impact. We quantify the discrepancy and recommend Distributed or MultiJVM.

The recent (and well-deserved) TLA+ attention motivated me enough to refresh my 20-year-old Haskell code that parses, pretty-prints, and evaluates TLA+ specs and expressions. Enjoy, copy, transcribe to other languages, etc. Maybe you too find it useful: github.com/ret/specifica
