The author used the AI tool Fable 5 to generate a 4‑layer RP2350 development board for an E‑ink display from a short English description and ordered it from JLCPCB. While the AI handled component placement, it left many DRC errors and routing gaps, requiring manual fixes and highlighting the limits of current AI‑driven PCB design.
CERA-MoA proposes a reinforcement‑learning loop where a router and a set of LLM agents are trained together. A “familiarity” estimator reads mid‑layer hidden states to predict each agent’s competence on a query, letting the router activate only a minimal subset of agents that meet a cumulative confidence threshold. The system also feeds targeted training examples to agents based on their evolving…
Replica‑aware routing (public beta) lets ClickHouse Cloud users pin a query stream to a specific replica by sending a custom header (HTTP) or overriding the TLS SNI (native). The proxy (Envoy) hashes the tag and consistently forwards all requests with the same tag to that replica, giving read‑after‑write consistency for temporary tables, session objects, and warm replica caches. Stickiness is bes…
Codename One adds a portable routing API (com.codename1.maps.routing) that separates route discovery from map rendering, offering a simple two‑line `showRoute` helper and a full callback‑based flow for custom UI, multiple alternatives, waypoints, and encoded polylines. The default service uses OSRM (no API key), but the design lets you plug any provider or self‑hosted engine via a `RouteService`…
