Focusing on Java backend development, covering application architecture from top-tier internet companies (high availability, high performance, high stability), big data, machine learning, Java architecture, and other popular fields.
The article analyzes Hermes Agent, a self‑evolving AI assistant from Nous Research, comparing its persistent memory, automatic skill evolution, deployment simplicity, and open‑source model swapping against OpenClaw, and provides step‑by‑step installation, migration, and advanced usage instructions for developers.
Despite headlines claiming AI will replace developers, hiring for engineering roles has surged to record highs, a trend explained by the 19th‑century Jevons paradox where efficiency gains actually expand total resource consumption, reshaping the software industry’s demand dynamics.
The article explains how Java 26’s native support for RFC 9562 UUIDv7 provides an ordered, unique, and standards‑compliant distributed identifier, compares it with traditional UUIDs and Snowflake, shows the new API usage, highlights hidden pitfalls, and offers practical best‑practice guidelines for production deployment.
This article presents a comprehensive guide to 16 practical Redis use cases—including caching, distributed locks, global IDs, counters, rate limiting, bitmaps, shopping carts, timelines, message queues, lotteries, likes, product tagging, filtering, follow‑recommendation models, and ranking—complete with code snippets and data‑structure examples.
This article provides a detailed walkthrough of JetBrains AIR, an AI‑native IDE, covering its core concepts, quick‑start installation on macOS, project opening methods, task definition workflow, permission settings, context addition, task management, review process, MCP server integration, and overall benefits for AI‑assisted development.
This guide explains the fundamentals of OCR, introduces Tesseract and its Java wrapper Tess4j, shows how to download language data files, configure a Spring Boot 3 project with Maven dependencies and YAML settings, and provides comprehensive test code for Chinese, English, and mixed‑language image recognition.
The recent collapse of AI coding assistants reveals how over‑reliance on these tools has eroded developers’ core programming skills, prompting a call to revive fundamental coding practices such as manual debugging, JVM optimization, and design‑pattern mastery.
This article examines why encrypted data hampers fuzzy queries, categorizes three implementation approaches—from naïve in‑memory decryption to conventional token‑based indexing and advanced algorithmic schemes—evaluates their performance, storage overhead, and security trade‑offs, and provides practical references.
The article dissects Spring 7.0.4’s critical deadlock bug, explains several other subtle fixes, details three major performance optimizations that can cut startup time by up to 50 % and up to 20 % request latency, and provides practical upgrade guidance for Kubernetes‑deployed Java services.
Spring Boot’s default Open Session in View (OSIV) keeps Hibernate sessions open throughout the request, silently triggering lazy‑loaded queries during JSON serialization, leading to N+1 problems and massive DB load under load, but disabling it and using explicit fetch joins restores performance.
