- Sep 30, 2026 Why RTP Timestamps Do Not Count Seconds RTP timestamps advance at the codec clock rate, which makes arithmetic modular and stream-relative; the rules that follow for wrap, comparison, and cross-stream sync. internet protocols
- Aug 15, 2026 Wall-Clock Timestamps Do Not Order Distributed Events Why two machines reading the same instant produce different numbers, how far the disagreement grows between synchronizations, and what an interval-bounded timestamp can still support. distributed systems
- Jul 11, 2026 Correlating Logs Across Devices When Clocks Disagree How clock offset and resolution error bound the accuracy of a merged timeline, and how to order events from independent devices without trusting their timestamps. networking
- Mar 17, 2026 Timestamps, RTTM, and Protection Against Wrapped Sequences How an echoed timestamp lets a sender time a retransmitted segment, why PAWS rejects segments by timestamp rather than sequence number, and what the option costs per segment. networking
- Feb 20, 2026 Reproducible Builds: The Sources of Nondeterminism in Compiler Output Two builds of identical source differ because something in the environment leaked into the artifact. The taxonomy of those leaks, and the normalizations that remove them. security
- May 17, 2025 Discovery and Finish Times: What DFS Edge Classification Encodes How the two timestamps recorded by depth-first search partition a directed graph into tree, back, forward, and cross edges, and why undirected graphs admit only two of those classes. algorithms
- May 13, 2024 The RTP Fixed Header: Twelve Bytes That Carry a Media Stream What each field of the 12-byte RTP header means, why sequence numbers and timestamps are independent, and which failures the design accepts to stay small. internet protocols
- Jan 26, 2024 Filesystem Timestamps and Why Timestomping Leaves a Seam Which timestamps an application can set, which only the kernel writes, and how the divergence between them exposes an attempt to backdate a file. security
