Choosing the Right Architecture Style: Why 'It Depends' Is the Only Honest Answer

This article explains why architecture style selection has no standard answer, detailing the forces driving architectural trends, the prerequisite analysis of domain, characteristics, data, cloud, organization, and processes, and the three key decisions between monolith vs distributed, data placement, and synchronous vs asynchronous communication.

Orchestration-Driven SOA: Topology, Pitfalls, and Lessons for Modern Architects

This article dissects orchestration-driven SOA, a 1990s enterprise architecture pattern centered on a central ESB and strict service taxonomy, explaining its layered topology, how reuse led to tight coupling and bloated models, the difficulties of distributed transactions, and why its failures directly inspired modern microservices principles.

How Jackson Rewrote Buffer Pooling for Java Virtual Threads

Jackson replaced its ThreadLocal-based buffer recycling with a pluggable RecyclerPool abstraction, iterated through multiple default pool implementations including a flawed LockFreePool, removed the leaky LockFreePool in 3.x, and fixed a TOCTOU race in BufferRecycler using atomic updates.
