我的 HMODULE 的最低位被置位意味着什么?
本文解释了当 HMODULE(模块句柄)的最低位被置位时的特殊含义。通常情况下,HMODULE 的低位不应被设置,但有一种特殊情况——当这个位被置位时,表示该句柄是一个特殊的“伪句柄”或标记,用于指示某些特定的系统内部状态或优化。文章详细说明了这种机制的工作原理及其在 Windows 编程中的实际应用场景。

The author rejects becoming a "reverse centaur"—a term for humans forced to review machine-generated code—after observing a surge in LLM-produced pull requests to his open source projects. Despite his personal decision not to use generative AI coding tools, he now spends increasing time reviewing code written by AI and explains how he resists this role.
The author, who once advised his sister to use code libraries without fully understanding them, now finds himself unable to commit AI-generated code he doesn't fully comprehend. He recounts spending 10 hours fixing code that an LLM produced in 12 minutes, and notes that while others trust AI code generators like a car engine, his need to understand every line negates any productivity gains.
The article argues that many single-page app developers misuse divs or buttons with onclick handlers instead of proper anchor tags for navigation, breaking browser history, accessibility, and native link features. The author urges using native `<a href>` elements or framework Link components.
The article argues that disallowing trailing (or leading) separators in languages like JSON, Haskell, and Prolog was a design mistake, as it makes adding or removing elements more complex. It highlights languages like Python, Go, and Alloy that permit trailing commas, and notes potential parsing ambiguities when trailing separators are used in control-flow contexts.
The article argues that Lucas Costa's concept of "backpressure" for systems handling code-generating AI is a misnomer. Backpressure signals upstream processes to slow down, while Costa's suggestions are about improving quality, not reducing quantity. The author proposes "lean manufacturing" as a more accurate analogy for managing unstable inputs from AI-generated code.
