Higher-Kinded Types and Type Constructors
Higher-kinded types let libraries abstract over type constructors while keeping their element relationships and laws visible.
Idempotency Keys and Exactly-Once Delivery
Safe retries with idempotency records, payload hashes, transactions, inbox/outbox patterns, and honest delivery guarantees.
String Matching: KMP, Z, and Rolling Hashes
Compare deterministic and hash-based substring search while making collisions, Unicode units, and verification contracts explicit.
Defending LLM Applications Against Prompt Injection
Defend LLM applications by modeling prompt injection as a trust-boundary and capability problem, then verify controls with adversarial tests and operational evidence.
Resilient Outbound HTTP Clients
Build outbound HTTP clients that reuse connections, honor one deadline, retry only safe failures, bound responses, and expose useful telemetry.
Load Balancing from Round Robin to Consistent Hashing
Choose request-placement algorithms by workload cost, locality, health evidence, churn, and hotspot behavior rather than by name alone.
Table Partitioning Without Operational Surprises
Operate native table partitions as one logical database table through deliberate pruning, indexing, lifecycle automation, and reversible migration.
Web Components and Shadow DOM in Practice
Build Web Components as durable platform contracts across lifecycle, composition, styling, forms, accessibility, SSR, and frameworks.
Plugin Architectures and Stable Extension Points
Build plugin systems around narrow versioned contracts, explicit capabilities, isolated execution, deterministic lifecycles, and reusable conformance tests.
Sizing Connection Pools and Worker Pools
Size connection and worker pools from fleet-wide resource budgets, measured service demand, queue deadlines, and load curves instead of arbitrary defaults.
From Sockets to Packets: Inside the Network Stack
Trace TCP bytes through host buffers, protocol state, kernel queues, drivers, and the NIC while preserving backpressure.
Testing Concurrent Code Deterministically
Turn thread schedules into replayable test inputs with controlled execution, model exploration, invariant checks, race detection, and seeded stress.
