- Apr 11, 2026 Review Metrics and the Confounders That Invert Them Why latency, comment density, and approval counts measure queueing and authorship as much as review quality, and which quantities remain interpretable under those confounders. software engineering
- Nov 24, 2025 Measuring Latency Under Load Without Fooling Yourself How to design a delay measurement that separates fixed path delay from queueing, which load patterns expose bufferbloat, and why idle-path numbers mislead. networking
- Oct 2, 2025 Measuring Disorder to Size a Lateness Budget How to derive the watermark delay and allowed lateness from the arrival-delay distribution, and why a percentile is the only honest input to that choice. data engineering
- Jun 20, 2025 Little's Law as a Consistency Check on Load Measurements How the identity connecting concurrency, arrival rate, and residence time exposes inconsistent measurement sets, plus the sampling errors and boundary conventions that make a correct system appear to violate it. performance engineering
- Aug 23, 2024 Checking Contrast Against What Renders, Not What Is Declared Computed styles, compositing, canvas readback, and the sampling decisions that decide whether a measured ratio corresponds to anything a reader sees. accessibility
- Aug 23, 2024 Measuring Alert Fatigue Instead of Describing It Which quantities make page volume and actionability comparable across rotations, how to collect them without rewarding the wrong behaviour, and how the numbers drive deletion. devops
- Dec 25, 2023 What ICMP Echo and TTL Probing Actually Measure The difference between the forward and return paths a traceroute samples, why hop times are often wrong, and what rate limiting on the control plane does to the numbers. networking
- Apr 28, 2023 Probing High-Speed Nets Without Measuring the Probe Why a scope probe loads the node it measures, how ground-lead inductance dominates above a few hundred megahertz, and which probing methods keep the measurement honest. hardware engineering
- Mar 21, 2023 Working Set Size and the Miss-Rate Cliff Why memory performance degrades in a knee rather than a slope, how capacity and associativity produce the knee, and how to find its location empirically. performance engineering
