Redefining the Backend: How Workers, Triggers, and Functions Turn Agents into First-Class Workers

The article argues that the traditional separation between AI agent harnesses and back‑ends creates debugging complexity, and proposes redefining the backend with three primitives—worker, trigger, and function—so that agents become equivalent to services or queues, enabling real‑time discovery, scalable extensibility, and unified observability across heterogeneous components.

Why PHP Workers Never Release Memory: The Hidden Block Allocation Pattern

When moving from PHP‑FPM to long‑running processes like RoadRunner or Laravel queue workers, memory usage climbs and never drops, a pattern caused by PHP’s Zend memory manager block allocation, reference counting, and GC behavior, which can be mitigated by redesigning code and worker strategies.
