This article examines Baidu's Tekes platform—its evolution from automated component publishing to a full‑stack mobile DevOps service—detailing its architecture, workflow engine, event‑driven pipeline, and how it boosts development efficiency across hundreds of repositories and product lines.
Reflecting on China’s Programmer’s Day, the author argues that moving from mere developers to true software engineers—by mastering engineering principles, design, project management, and open‑source culture—is essential for upgrading the nation’s 4 million‑strong software workforce and overcoming low‑quality, involutionary development.
This guide explains why raw iOS crash logs are unreadable, introduces dSYM files and DWARF debugging information, shows how to match UUIDs, compute addresses, and use both Xcode and command‑line tools for local symbolication, and describes a scalable online solution for massive crash‑log processing.
This article explores the fundamentals of HTTP cookies within WKWebView, detailing how cookies are stored in memory or disk, the roles of UIProcess, WebContent, and NetworkProcess, and provides code examples for front‑end JavaScript, back‑end headers, and iOS client APIs.
Baidu’s live‑streaming team cut startup latency by dissecting the three‑phase launch process, streamlining business‑logic handling, employing HTTPDNS pre‑resolution, forcing first‑frame rendering, low‑bitrate fallback, pre‑loading kernels, direct H.264 SPS/PPS parsing, and HLS m3u8 pre‑fetching, achieving sub‑3 ms DNS and hundreds‑millisecond overall gains.
This article dissects the WKWebView loading pipeline on iOS, explaining the three WebKit processes, their communication, the step‑by‑step request flow, and the detailed behavior of each WKNavigationDelegate method, providing practical insights for performance tuning and debugging.
The Baidu App’s T7 browser kernel team optimized its HTTPCache and MemoryCache by enabling main‑document and file‑protocol caching, introducing a fixed‑size LRU cleanup, providing custom preload/query APIs, and leveraging NoState Prefetch, which together cut page‑load latency by over 30 % and markedly improve user experience.
The article explains how to design and implement ESLint and StyleLint plugins for the San‑Native framework, detailing AST generation, processor creation, rule definitions for JavaScript and CSS, configuration sharing, and how these tools provide real‑time linting feedback for developers.
This tutorial walks iOS developers through downloading the WebKit source, configuring and compiling it, setting up a debugging project or using the MobileMiniBrowser demo, and analyzing WKWebView’s multi‑process architecture—including UI, WebContent, Network, and Storage processes—to troubleshoot and profile rendering behavior.
This article explains the concept of a virtual tree, why it is needed for rendering massive data sets, and provides a step‑by‑step implementation—including flattening the tree, calculating visible nodes, simulating scroll, and decorating the list—demonstrating a speedup from 26 seconds to 0.19 seconds.
