- Jun 21, 2025 Interrupt Latency, Tick Overhead, and the Kernel Cost Budget How to decompose the delay from an external event to a task running into measurable pieces, and which kernel configuration choices move each piece. embedded systems
- May 5, 2025 Clock Networks, Global Buffers, and Skew Budgets Why a clock reaches every register through a dedicated balanced tree, what skew and jitter cost a timing budget, and when a clock must be routed on general interconnect instead. hardware engineering
- Mar 31, 2025 Reading Loss and Round-Trip Time from RTCP Sender and Receiver Reports How the fraction-lost, jitter, and LSR/DLSR fields are computed, why the arithmetic is fixed-point, and where the round-trip estimate breaks down. internet protocols
- Dec 16, 2024 Retry Budgets and the Load Multiplication They Prevent How per-client retry counts turn a partial dependency failure into a full outage, and why a budget denominated in successful requests bounds the amplification instead. backend systems
- Jun 23, 2024 Retry Accounting When the Scheduler Chooses the Moment How attempt counts, backoff, and jitter interact with deferral, why a retry that waits for a maintenance window needs different arithmetic, and where budgets go wrong. mobile computing
- Mar 30, 2024 Retry Storms When a Network Comes Back Recovery is harder than outage: every queued client retries at once, and the mechanisms that keep a system stable are jitter, admission control, and a drain rate the server can sustain. mobile computing
- Sep 8, 2023 Detecting Periodic Beacons in Flow Telemetry Why fixed-interval check-ins are visible in timing even when the payload is encrypted, how jitter and distribution shape change the test, and where the statistical approach fails on sparse data. security
- 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 3, 2023 Retry Policy Design: Error Classification, Backoff, and Jitter Which failures deserve another attempt, how exponential backoff and jitter change the arrival distribution, and why a retry can make an outage worse. data engineering
