- Oct 20, 2026 Sharded Counters, Padding, and False Sharing Why two independent counters placed next to each other can cost more than one shared counter, how cache-line granularity forces padding, and what sharding gives up in exchange. performance engineering
- Jan 24, 2026 Interface Drop Counters and What Each One Actually Attributes How kernels classify discarded packets into drop, error, and overrun counters, and why a clean counter set can coexist with a link that loses traffic. networking
- Dec 29, 2025 Counting Bloom Filters and the Price of Supporting Deletion Replacing bits with small saturating counters makes removal possible, but residue, overflow, and spurious decrements each introduce a distinct failure. data structures
- Dec 8, 2025 Hot Code Detection with Invocation and Back-Edge Counters How runtimes decide that a function or loop is worth compiling, why method entries and loop back edges need separate counters, and what the counter arithmetic gets wrong. language runtimes
- Aug 18, 2025 Counter Resets and the Extrapolation Inside rate() Why a monotonic counter loses its meaning when a process restarts, how reset detection reconstructs the increment, and what the edge extrapolation in a rate query assumes. observability
- Jan 24, 2024 Delta and Cumulative Temporality in Collection Pipelines How the two ways of reporting a sum interact with resets, why one is cheaper to transmit and the other cheaper to align, and how a pipeline converts between them without losing increments. observability
