• Garbage Collection Advanced: Incremental, Concurrent, Snapshot-at-the-Beginning, and Pauseless Collectors from Azul C4 to ZGC Colored Pointers · 2020-10-31

  A deep exploration of advanced garbage collection algorithms that eliminate stop-the-world pauses — incremental marking, concurrent collection, the snapshot-at-the-beginning barrier, and the pauseless collectors that make Java viable for low-latency applications.

• JIT Compilation: Tracing vs Method JITs, V8's Ignition+TurboFan Pipeline, HotSpot's C1/C2 Tiered Compilation, and Deoptimization · 2020-10-28

  A deep exploration of just-in-time compilation — how V8 and HotSpot turn JavaScript and Java bytecode into native code through multi-tier compilation pipelines, and the art of deoptimization that makes speculative optimization safe.
