FastMCP now powers over 70% of MCP servers, offering a Pythonic decorator‑based API that automates schema, validation and documentation, bridges prototype and production workloads, and enjoys a thriving ecosystem, which together explain its rapid adoption among AI developers.
The article analyzes why kkFileView, an open‑source Spring Boot microservice that leverages LibreOffice for document conversion, has become the go‑to solution for browser‑based file preview by examining its architecture, workflow, feature set, deployment options, performance tweaks, and comparisons with other approaches.
This guide lists the ten most useful DeepSeek Harness plugins, explains how to install them with a single command, highlights key features, usage scenarios, and the pros and cons of each, and offers layered recommendations for different user needs.
DeepSeek Harness, DeepSeek’s first Agent product, went from launch to 50,000 GitHub stars in 12 hours, thanks to its all‑plugin architecture, record‑breaking growth, and a lightning‑fast two‑step release, positioning it as an open‑source Agent operating system that rivals Claude Code and Pi.
Pi, an open‑source terminal AI coding agent created by libGDX founder Mario Zechner, outperforms competitors like Claude Code by using a minimalist design with only four primitive tools, a 200‑token system prompt, and model‑agnostic architecture, resulting in 99.93% cache‑hit rates, ultra‑low per‑task costs (~$0.028), full MIT licensing, and extensive extensibility.
Adding a column to a MySQL table with tens of millions of rows can lock the table for minutes or even hours, disrupting services, so this article evaluates six practical approaches—including native online DDL, offline maintenance, PT‑OSC, logical migration with dual‑write, gh‑ost, and partition sliding‑window—detailing their mechanisms, trade‑offs, and suitable scenarios.
Hutool 5 has become the de‑facto utility library for modern Java projects because it eliminates duplicated, error‑prone hand‑crafted utils, reduces code volume by up to 50%, offers a stable, modular API that works with JDK 8+, and provides ready‑to‑use features for strings, dates, files, HTTP, JSON, encryption and even AI integration.
Spring Boot 4.0, built on Spring Framework 7, requires Servlet 6.1, leading to the removal of Undertow support; the article explains the technical reasons, the impact on existing projects, and provides step‑by‑step migration paths to Tomcat or Jetty, including configuration changes and risk considerations.
Fastjson 1.x (versions 1.2.66‑1.2.83) contains a CVSS 9.8 remote‑code‑execution flaw that works with default settings, was disclosed in July 2026, and sparked heated community debate, while the library had already been unmaintained since 2024 and official guidance now recommends migration to Fastjson 2.x or enabling SafeMode.
The article analyzes the shift from Model Context Protocol (MCP) to command‑line interfaces (CLI) for AI agents, detailing MCP’s architectural complexity, token bloat, security risks, and passive tool design, while highlighting CLI’s on‑demand loading, composability, debugging ease, and growing enterprise adoption.
