The article examines how AI now writes the majority of code in leading tech firms—75% at Google and 70% in the author's team—backed by industry surveys, productivity gains, security concerns, common pitfalls, and the evolving skill set required of modern engineers.
DeepSeek V4 preview, released quietly on April 24, offers two models with 1 M token context and pricing 1/16 of Claude Opus, achieving near‑par performance on SWE‑bench and LiveCodeBench, while integration with Claude Code enables rapid project understanding, bug detection, refactoring, testing and documentation, saving days of work for under ¥6.
OpenAI’s April 23, 2026 launch of GPT-5.5 delivers record‑high scores on SWE‑Bench Pro (58.6%) and Terminal‑Bench 2.0 (82.7%), adds persistent multi‑file context, dynamic reasoning time, and token efficiency, while real‑world case studies show substantial productivity gains across engineering teams.
The article presents a step‑by‑step, three‑month‑tested workflow that embeds Anthropic Claude and OpenAI Codex into IntelliJ IDEA via the Continue plugin, enabling Java developers to auto‑generate CRUD code, unit tests, and refactorings, connect Claude to the database, and avoid repetitive coding tasks without purchasing a subscription.
The article explains how the Spring AI @Tool annotation transforms large language models from guesswork to real‑time data retrieval and action execution, presenting ten concrete scenarios—query, write, aggregation, cross‑system integration, proactive push, Text‑to‑SQL, role‑based access, external services, workflow triggers, and intelligent diagnostics—each illustrated with Java code, LLM decision flow, best‑practice tips, and cost considerations.
This guide explains the Model Context Protocol (MCP), its JSON‑RPC communication modes, compares Java implementations, and provides a step‑by‑step tutorial—including project setup, configuration, tool creation, registration, and integration with Claude Desktop and IDEA—while covering description best practices, security, validation, and production considerations.
This guide walks you through the two main ways to bring Claude Code into IntelliJ IDEA 2026.1—using the official Claude Code plugin and the deeper ACP protocol—detailing every configuration step, key differences, shortcuts, and common pitfalls so you can choose the best workflow for your development needs.
Spring Boot’s heavy runtime, driven by reflection and classpath scanning, incurs long cold starts and high memory usage, making it costly for serverless and edge deployments; lightweight frameworks like Quarkus, Micronaut, and Helidon shift work to compile time and offer native images, but introduce trade‑offs in dynamism, ecosystem coverage, and build complexity.
A night‑time SMS billing attack that drained ¥11,500 in two hours exposed flaws in a naïve Session‑based verification design, prompting a detailed, five‑layer defense architecture that combines gateway rate limiting, Redis token‑bucket controls, advanced captcha tracking, device fingerprinting, blacklist automation, and honey‑pot tactics to raise attack costs.
The article explains why major Chinese banks’ mobile apps feel outdated by examining how strict regulatory requirements, decades‑old COBOL‑based core systems, entrenched technical debt, and fragmented organizational structures force banks to prioritize compliance over user‑centric design, and how digital‑only competitors expose this gap.
