菜鸟面试官的一点思考

2025-06-26

“The boolean trap” is just one example of how seemingly simple modeling decisions can have unexpected consequences as systems grow. While booleans are perfect for their intended purpose – representing true/false technical states – they often fall short when applied to a domain. By choosing enums and enum sets we create code that is better prepared for the “real world”‘ of the problem domain.

Sometimes it’s better to rethink how we represent the state instead of blindly adding another boolean flag.

乱语：这位老哥说在领域模型内，使用布尔值不是很好，得用枚举或者是状态机。

A proof of concept (POC or PoC), also known as proof of principle, is an inchoate realization of a certain idea or method in order to demonstrate its feasibility[1] or viability.[2]

A proof of concept is usually small and may or may not be complete, but aims to demonstrate in principle that the concept has practical potential without needing to fully develop it.

乱语：简单翻译来看，就是对概念的证明。

流转知何世，江山尚此亭。
登临皆旷士，丧乱有遗经。
已识乾坤大，犹怜草木青。
长空送鸟印，留幻与人灵。

【词语力量354】犹怜草木青。“已识乾坤大，犹怜草木青”，即便是经历世事沉浮、阅尽人间沧桑，当俯下身子看到草木生发……

草木之枯荣于我之人生有何增益？春秋之轮换于我之富贵能添几何？生活之重担已令人不堪负，又有何心力去关心草木是否变青、春花是否再发？

翻看了一下 vite 的第一个 commit，大概知道热更新是怎么做到的了，像 vue/react 都需要框架级别的支持才行。

可视化寻路算法，来自宾夕法尼亚大学数学专业的大佬

Welcome to Pathfinding Visualizer! I built this application because I was fascinated by pathfinding algorithms, and I wanted to visualize them in action. I hope that you enjoy playing around with this visualization tool just as much as I enjoyed building it.
