- 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
- Apr 28, 2026 Depth, Width, and the Linear Regions of ReLU Networks Every rectified network is a partition of its input space into cells where it computes an affine map, and the count of those cells grows polynomially in width and exponentially in depth. deep learning
- Jan 7, 2026 Autoscaling as a Feedback Loop: Gain, Lag, and Why It Oscillates How a replica controller turns a metric into a desired count, why the control law is proportional rather than predictive, and how sampling lag and stabilisation windows prevent or cause oscillation. virtualization
- Jul 4, 2025 Forecasting Exhaustion for Saturation Alerts How a linear projection over a recent window turns a saturation alert from a percentage threshold into a deadline, why the projection is only valid for a bounded horizon, and where it breaks. observability
- Apr 23, 2025 Bulkhead Isolation and the Design of Partial Degradation Partitioning capacity so one dependency cannot consume all of it, and deciding in advance which features are worth serving when the partition is full. backend systems
- Apr 8, 2025 Placement as Bin Packing: Multi-Dimensional Fit and the Fragmentation It Creates Why a scheduler with free cores and free memory can still refuse a pod, how multi-dimensional packing produces unusable holes, and which scoring functions trade density against headroom. cloud infrastructure
- Apr 4, 2025 Queueing Bounds as a Deployment Design Test Using Little's law, utilization curves, and the Kingman approximation to decide whether a proposed deployment can meet a latency scenario before anything is built. software architecture
- Mar 5, 2025 Autoscaling Control Loops: Why the Metric Lags the Demand The feedback loop behind replica count: measurement windows, stabilization, and the delay stack that makes a fast scaler overshoot and an accurate one react too late. cloud infrastructure
- Feb 22, 2025 Why a Replication Slot Pins Write-Ahead Log and How to Bound It The retention rule that makes a slot hold log segments until a consumer confirms them, the disk consequence of an idle slot, and the settings that cap it. databases
- Oct 15, 2024 Rate and Capacity in the Sponge Construction How SHA-3 absorbs and squeezes through a fixed permutation, why capacity rather than digest width determines the security level, and what the rate costs in throughput. cryptography
- Aug 20, 2023 Autoscaling Model Servers on Queue Depth Rather Than Utilization Utilization-based autoscaling assumes work is interruptible and cheap to queue; for inference it produces oscillation, so the control signal has to be the wait time a request would experience. inference systems
- Jul 2, 2023 Interruptible Capacity: Eviction Notices, Checkpointing, and the Cost of Being Preempted What a preemptible instance actually promises, how the notice arrives, and which workload properties determine whether the discount is worth the interruption. cloud infrastructure
