Sharing common backend development knowledge.
This step‑by‑step tutorial shows how to integrate Claude Code with GitHub, configure the required GitHub App, set up GitHub Actions workflows for Issue mentions and Pull Request reviews, add necessary secrets, customize prompts, and adapt the setup for GLM models, turning Claude into an automated code‑review assistant.
This comprehensive guide walks you through the Claude Certified Architect exam structure, explains how Claude Code turns a language model into a full‑featured programming assistant, details installation on macOS, Linux and Windows, demonstrates tool‑use mechanics, context management, custom commands, and extending functionality with MCP servers such as Playwright.
This guide explains Claude Code’s agent loop, model choices, built‑in tool categories, project access scope, session handling, checkpoint and permission controls, and practical tips for efficiently using the AI‑driven terminal assistant to write, test, and refactor code.
This guide walks you through installing Claude Code, choosing and purchasing a model package, configuring the server via script or environment variables, switching models, using core commands, and applying its three operation modes to develop a complete project from start to finish.
This article compares the execution models of C/C++, Java, and Python, explaining how compiled machine code, bytecode with JVM, and interpreted bytecode with the Python virtual machine operate, and illustrates each process with example file structures and compilation steps.
This guide covers Python's core numeric and string types—including ints, floats, complex numbers, booleans, and bytes—explains common pitfalls like floating‑point precision, demonstrates formatting options, shows how to use enums and SQLAlchemy for cleaner code, and offers practical advice for readable and efficient scripting.
This tutorial explains how to register and inject a third‑party implementation like SwimCoach into a Spring Boot application using a @Configuration class and @Bean methods, covering bean creation, custom IDs, qualifier usage, and practical scenarios such as integrating AWS S3 clients.
This guide explains the Spring bean lifecycle, focusing on the key initialization and destruction hook methods using @PostConstruct and @PreDestroy annotations, with code examples, usage tips, and important considerations for prototype-scoped beans.
This article explains how Spring manages bean instances, compares singleton and prototype scopes with concrete code examples, and shows why two injected beans may be equal or different depending on the @Scope annotation applied to the component class.
This article explains Spring's default eager bean creation, demonstrates how to add @Lazy annotations or a global property to defer bean instantiation until needed, and discusses the benefits and drawbacks of lazy loading with code examples and runtime observations.
