- Aug 18, 2026 Earliest-Deadline-First and What Happens When the System Overloads Why dynamic deadline ordering is optimal on one processor, how the utilisation test differs from the fixed-priority one, and how the schedule degrades after a bounded overload. embedded systems
- Aug 14, 2026 Metastable Failure and the Load That Keeps a System Down Why some outages persist after the trigger is gone, how retries and cold caches hold a system in a low-capacity state, and what it takes to break the loop. backend systems
- Jun 28, 2026 Timeout Budgets, Deadline Propagation, and the Arithmetic of Retry Amplification How a timeout that is short relative to the service latency turns into extra load, why retries must be bounded per request rather than per attempt, and how a remaining-time budget propagates across tiers. performance engineering
- Jun 17, 2026 Capacity Failure Modes Under Peak Load The specific mechanisms that turn a load peak into an outage: queue overload, resource leaks under retry, cold cache amplification, and the asymmetry between degradation and recovery. performance engineering
- Jul 30, 2025 Bounded Queues, Backpressure, and What to Drop Under Overload Why an unbounded queue converts a capacity problem into a latency problem, how a queue bound is derived from a target latency, and the shedding policies that decide which requests are refused. performance engineering
- Nov 2, 2024 Feedback Effects That Change Service Demand How retries, timeouts, circuit breakers, and admission control alter the load a system receives, and why a positive feedback loop makes a capacity plan invalid at exactly the moment it is needed. performance engineering
