中文导读
来自 Microsoft 的 Brian Beckman 用一小时白板推演，仅用初等数学从函数组合与 monoid 一步步推导出 monad，专为一线实战程序员打造，拒绝晦涩范畴论黑话。
为什么 HN 推它
HN 上常年霸榜的 monad 入门神片，许多开发者表示看了无数教程没懂，唯独被这期彻底点透。
「作为一线工程师，想搞懂 monad 看这 1 小时的视频就全够了。」HN 网友原话：This video is all you, as a practicing programmer, need to know about monads and it's just 1 hour long.
英文原摘要（HackerTube / Claude 整理）
Microsoft's Brian Beckman gives an hour-long, whiteboard-style walk through monads, building from function composition and monoids using school-level math. It is aimed at practicing programmers rather than category theorists.
HN repeatedly recommends it as the clearest and most correct beginner explanation of monads, with several commenters saying it finally made them click.
HN 上的提及
Here's a nice video that explains monads fairly simply
The bottom-up people start with the hardware and only add abstractions and trade performance where necessary
Brian Beckman explained one such axis, as an aside, in "Don't fear the Monad" [1]
I found this introduction to the concepts of functional programming (functional composition) to be useful
This whole video is worth watching
