This article explains why Vue SSR performance suffers, introduces cache concepts and eviction policies, and walks through a complete, O(1) LRU cache built with JavaScript using a hash map, doubly‑linked list and arrays, complete with code and visual examples.
NetEase Media migrated SparkSQL to Kubernetes in 2021, using storage‑compute decoupling, hybrid deployment, custom scripts, Kyuubi failover, and extensive monitoring and resource governance, which cut cluster size by over 30% while keeping CPU utilization above 80% and GC throughput above 95%.
The article explains how NetEase Media rebuilt its core services with Go, created the open‑source ngo framework to unify dependencies, health‑check, tracing, configuration and OpenID support, and provides detailed code examples and integration guidelines for backend developers.
To tackle the massive, multimodal tagging challenge of short‑video platforms—characterized by a huge long‑tail tag set, sparse annotations, and uneven modality contributions—the authors propose a two‑stage recall‑ranking system that first retrieves candidates via text, visual, audio and classification cues, then refines them with contrastive learning and extensive hard‑negative sampling, achieving 0.884 tag accuracy in a real‑world news video recommender.
Facing high memory usage and slow builds with Java SpringBoot, NetEase Media switched to Go in 2020, rebuilt core services, and created the cloud‑native ngo framework to deliver lighter containers, faster compilation, built‑in business libraries, tracing and monitoring, now running in production while hiring engineers.
This article explains how to create a non‑intrusive Kubernetes admission webhook that injects custom volumes and volume mounts into Knative pods, covering the underlying admission control concepts, Go implementation, TLS setup, deployment manifests, and verification steps.
NetEase Media details its year‑long journey building a cloud‑native container platform—covering foundational concepts, a robust infrastructure framework, Kubernetes deployment, solutions to pre‑containerization challenges, and practical best practices such as graceful shutdowns, health probes, and resource‑limit configurations.
The article explains how to create a seamless medal‑unlock animation using layered SVG clipPath tricks and a four‑step CSS process, and how to build an interactive gyroscope effect with deviceorientation events, while emphasizing performance‑friendly practices such as using transform, opacity, requestAnimationFrame, and avoiding reflow‑inducing properties.
The NetEase News iOS team adopted a three‑layer componentization strategy—foundation, common, and business—standardizing code conventions, Git workflow, and CI‑driven reviews, encapsulating third‑party libraries, managing dependencies via injection and mediators, and distributing binary pods, which reduced the main project to a single file while expanding reusable components to over 250, achieving low coupling and high cohesion.
The article describes how NetEase adapts a pre‑trained BERT model to classify news articles into ultra‑short, short, or long timeliness categories by combining rule‑based strong and weak time cues, key‑sentence extraction, domain‑embedding fusion and multi‑layer semantic aggregation, achieving accurate and interpretable predictions for its platform.
