Gaode’s Adoption of OceanBase: Architecture, Practices, and Future Roadmap

Gaode migrated its core navigation, traffic, and financial services to OceanBase, leveraging Paxos‑based multi‑replica consistency, LSM‑Tree storage, and distributed transactions, selecting multi‑point write for massive sync workloads and central‑write for latency‑critical queries, achieving sub‑millisecond latency, significant storage savings, and a roadmap toward broader cost‑effective, serverless deployment.

Implementing Automatic Cruise Navigation on AMap with Three.js

The article walks through building an automatic cruise navigation effect on AMap with Three.js by acquiring route data, merging GeoJSON paths, loading a 3D vehicle model, animating its movement and camera follow using TWEEN, and blending the NPC layer with satellite and 3DTiles layers for a smooth autonomous navigation experience.

Technical Overview of Augmented Reality Head‑Up Display (ARHUD) for Automotive Navigation

ARHUD integrates augmented‑reality graphics into a vehicle’s head‑up display, projecting speed limits, lane cues and navigation data at a virtual distance beyond 10 m and a wide field of view, while requiring precise eye‑point tracking, coordinate conversion, and advanced optics such as TFT‑LCD, DLP or LCOS to overcome challenges of brightness, size, alignment and limited FOV for safe, low‑cognitive‑load driving.

The Essence of Learning: Active vs. Passive Approaches and Their Impacts

Learning enriches knowledge but, when pursued passively or excessively, can crowd out personal thought, stifle creativity, and make thinking rigid, so a healthy approach blends active, experience‑based insight, selective classic sources, and continual self‑reflection to turn knowledge into genuine understanding.

Simplifying Component Interaction in Low-Code Frontend Development

The platform replaces complex event‑driven code with a code‑free, expression‑only “saveEffect” mechanism that lets non‑technical users visually link component states by selecting source and target paths and optional transformation functions, simplifying low‑code frontend development and enabling independent workshop creation.

Software Architecture Design: Principles, Patterns, and Practical Approaches

The article defines software architecture as a business‑driven abstraction of system structure, explains core design principles such as SOLID, Ockham’s Razor, DRY, YAGNI, KISS and POLA, illustrates LSP violations, surveys layered, hexagonal, onion and DDD styles, and shows how applying Dependency Inversion in a large C++ codebase yields a simple, maintainable, business‑aligned architecture.
