- Jul 7, 2026 Shard Routing and Ownership Metadata: The Directory That Must Not Disagree How clients find the shard for a key, what happens when the routing table is stale, and why ownership epochs turn a racy handoff into a detectable error. databases
- Jul 6, 2026 Lookup Tables, Carry Chains, and the Routing Fabric How a configurable logic cell implements arbitrary Boolean functions from SRAM bits, why adders get a dedicated carry path, and why interconnect rather than logic sets the achievable frequency. hardware engineering
- Feb 27, 2026 Placement, Routing, and Congestion in the Logic Array How the placer decides where each cell goes, how the router allocates wire segments, and why a design can fail to route while the array looks half empty. hardware engineering
- Dec 27, 2025 Fat Trees, Toruses, and the Bisection Bandwidth Ceiling How the worst-case cut through a network bounds global traffic, why a torus gives up bisection bandwidth for constant degree, and where each topology fits. scientific computing
- Jun 6, 2025 Path Vectors, Policy, and Why BGP Does Not Minimize Anything How an exterior gateway protocol carries a whole path to detect loops, why the decision process ranks policy above distance, and what that costs at convergence time. computing history
- May 20, 2025 Offline Navigation, App Shell, and Fallback Routing Why navigation requests need their own handling in a service worker, the trade between shell-based and per-URL caching, and how navigation preload removes the worker-startup delay from the critical path. web platform
- Apr 12, 2024 Shard Routing and Replica Consistency in Distributed Search How a search index is split across many machines, how a query fans out to shards and merges their results, and how replicas stay consistent with their primary shards. information retrieval
- Dec 28, 2023 Moving Workloads with Overlapping Private Address Space Why two RFC 1918 networks that both use 10.0.0.0/8 cannot be joined by routing alone, how translation state makes the link fragile, and where addresses embedded in payloads defeat it. cloud infrastructure
- Apr 29, 2023 Routing Metadata Staleness and the Cost of a Wrong Guess Every client caches a map from key to node, and every cache is wrong eventually. How epochs, redirects, and fencing turn a stale guess into a retry instead of a lost write. distributed systems
