This article explains the design and implementation of a DPDK‑based domain interception gateway that analyzes HTTP/HTTPS traffic, uses TCP connection hijacking and DPDK’s KNI interface to block unregistered domains, detailing architecture, packet processing flow, and the trade‑offs of this approach.
This article explores the fundamentals of load balancing in microservice architectures, detailing both stateless and stateful strategies such as round‑robin, random, hash, and weighted algorithms, and demonstrates how go‑zero and gRPC implement these mechanisms through custom balancers, service discovery, and request scheduling.
This guide shows how to automatically extract subtitles from English videos using OpenAI's Whisper, translate them into Chinese with a locally‑deployed Ollama large language model, and finally merge the bilingual subtitles back into the video using FFmpeg, all with GPU acceleration.
This article explains the architecture, deployment process, and custom node configuration of dedicated Kubernetes clusters for SaaS and ToB scenarios on public cloud, highlighting differences from internal setups, networking challenges, and resource‑optimization solutions.
This article explains the Simulcast standard in WebRTC, compares it with transcoding and SVC, describes how an SFU rewrites RTP headers for seamless layer switching, outlines congestion detection using TWCC, and presents automated bandwidth allocation strategies to optimize video quality and reduce bandwidth in large‑scale meetings.
This article explains the fundamentals of Container Network Interface (CNI), outlines common plugin implementations, and dives deep into Alibaba Cloud's Terway solution, detailing its elastic ENI support, Vethpair and ipvlan modes, resource management, scheduling, network policy integration, and future enhancements such as eBPF.
This article explains common service problems and presents practical solutions such as rate limiting, circuit breaking, and degradation, detailing their principles, implementation methods—including Nginx, token‑bucket, sliding‑window algorithms, and Go‑zero code examples—while highlighting key considerations for building resilient microservice systems.
This article explains Ozone's object storage architecture, its evolution of metadata management using distributed KV stores like Apache Cassandra, and the performance optimizations—read/write separation, unlimited scaling, and partitioning—that enable high‑throughput, low‑latency handling of massive datasets.
This article explains how Arkit, a Go‑based unified monitoring agent, collects and parses data from multiple sources, leverages Go plugins for flexible, high‑performance processing, provides custom plugin development guidelines, and discusses the performance benefits and limitations of the plugin system.
This article explains the background, evolution, and implementation steps of iOS screen sharing using Apple's ReplayKit framework, covering cross‑app sharing architecture, extension setup, data handling, UI controls, and key development considerations such as memory limits and inter‑process communication.
