Sharing Java developer knowledge, practical articles, and continuous insights into computer engineering.
The article introduces a "diverge‑converge" skill that guides an AI agent to first expand a vague idea into a comprehensive map of possibilities and then iteratively lock decisions, enabling you to produce a complete, implementable MVP plan for any field within half an hour.
Apple's WWDC 2026 introduced Apple Intelligence 2.0, a rebuilt Siri AI, and a Core AI framework, illustrating five concrete agent paradigms—system‑wide integration, deep personal context, standardized action protocols, privacy‑first architecture, and goal‑driven interaction—while noting the service remains unavailable in mainland China.
The article proposes a systematic Agent Skill Hub that organizes, versions, releases, deploys, and rolls back AI Agent capabilities using software‑package‑style practices, illustrated with a concrete image‑download skill, directory conventions, metadata files, and a Spring AI Alibaba runtime loading strategy.
This article presents a practical collection of high‑frequency tools—including Python, Shell, SQL, Mermaid, Pandoc, curl, ImageMagick, and PlantUML—that can be wrapped as Agent Skills to give AI agents real execution power, illustrated with concrete prompts and scripts that cut manual work from hours to seconds.
This article explains the high‑severity remote code execution and data‑theft flaw discovered in Apifox, outlines how malicious scripts can steal SSH keys, Git credentials and shell history, and provides step‑by‑step Mac and Windows commands for self‑inspection and comprehensive remediation.
This article analyzes the evolution of AI agents, compares multi‑agent and single‑agent frameworks, introduces the concept of an AI Tool Platform, and presents a five‑layer enterprise AI architecture with a step‑by‑step Java implementation roadmap for real‑world automation.
This article explains how to design scalable, collision‑free coupon codes by using a custom binary layout, bit‑field allocation, checksum validation, obfuscation, Base62 encoding, and provides complete Java‑style algorithms and database schema for production use.
This article traces the evolution of computers from philosophical logic to modern digital circuits, explains how logical gates enable computation, introduces bitwise operators with practical code examples, and analyzes a coupon‑code generation algorithm that combines masking, shifting, and XOR operations for secure identifier creation.
This article explains how to build a production‑grade short‑link service, covering the background of SMS short URLs, Base62 encoding principles, database schema design, request routing, security measures such as custom alphabets, rate limiting, and signed links, and additional management features for operation and monitoring.
This article explains common pitfalls when handling file uploads in Spring Boot, including temporary file lifecycle causing FileNotFound errors in asynchronous processing, and character encoding mismatches that lead to garbled text, and provides practical solutions such as size limits, main‑thread parsing, and BOM‑based charset detection.
