Vibe Coding sounds appealing, but have you ever felt exhausted by it, thinking it's just a facade? This article will introduce a simple yet powerful approach that allows you to master AI and turn it into your true programming partner.

This article, through the author's experience of developing a music practice website, explains how programmers can overcome career burnout and rediscover the joy and sense of accomplishment of programming as a creator by establishing a complete closed loop from conception to implementation.

In the AI-assisted coding era, Java's verbosity and reliance on complex frameworks and design patterns make it less efficient than languages like Python when collaborating with AI tools, potentially leading more developers to abandon Java in future technology choices.

Using Netty as an example, this article provides an in-depth analysis of how Java retrieves actual generic types from bytecode through inheritance hierarchies after type erasure.

Explains prefix-sum construction and range queries, then applies the technique to several subarray-sum problems.

Compare three coin-change problems and the DP modeling differences among minimum coins, combinations, and permutations.

Model the stock-trading family as a state machine and systematically derive DP states and transitions under different transaction limits.

Uses several dynamic-programming problems to explain state selection, subproblem design, and state dependencies.

Uses maximum-subarray problems to explain subproblems defined by subarrays ending at a specific position.

Derive the 2D dynamic-programming state, recurrence, and operation-order optimization for edit distance from its recursive subproblems.
