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.
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.
This article introduces the open‑source "awesome‑openclaw‑usecases" repository, which collects over thirty practical AI‑agent workflows across six functional modules—social media, creativity, DevOps, productivity, research, and finance—providing ready‑to‑run examples, configuration steps, and integration tips for users of OpenClaw.
This article analyzes OpenClaw's role as a flexible AI‑driven shell, explains why its capabilities are hard to define, and reveals how businesses can profit by turning its programmable digital‑labor potential into concrete services and products.
This article compares Git's merge and rebase commands by walking through a realistic scenario where two feature branches diverge from master, showing how each method resolves conflicts, affects commit history, creates merge commits, and outlines best‑practice guidelines for choosing the appropriate strategy.
This article introduces AgentScope Java, a multi‑agent development framework that lets Java developers build intelligent assistants and collaborative agents with built‑in reasoning, tool use, memory, RAG, and Spring Boot integration, providing production‑grade performance and easy setup.
This guide walks you through installing OpenClaw, an AI‑powered computer automation agent, on a macOS machine using Docker, configuring the MiniMax model, setting up the Feishu chatbot plugin, and verifying that the system responds to commands, all with step‑by‑step commands and screenshots.
