通俗理解Python中的装饰器
下面是一个简单的装饰器案例，展示了如何创建和使用装饰器：# 定义装饰器函数def my_decorator(func): def wrapper(): print("Something is happening func() print("Something is happening after the function is called.") 当我们调用 say_hello() 函数时，实际上是调用了经过装饰后的函数，输出结果如下：Something is happening before the function is called.Hello Something is happening after the function is called.这个例子展示了如何使用装饰器来在函数执行前后添加额外的逻辑，而不需要修改原始函数的定义。

A tale of an impossible bug: big.LITTLE and caching
Nothing could reasonably explain what was happening, and the crash was happening with valid instructions With that we came to our first good hypothesis: Bad cache flushing was happening only on the upper 64 So what was happening is that __clear_cache would be called first on a big core and cache 128 as the

“Something Big Is Happening”｜大事确实在发生，是一场漫长而温和的重构。我们每个人都将是参与者，而非旁观者。
Matt Shumer在推特的《Something Big Is Happening》引爆了硅谷。文章描绘了一幅AI指数级进化、认知工作被快速替代的图景，让无数白领陷入职业焦虑。 01 — 一件大事正在发生 爆款原文传送门：https://shumer.dev/something-big-is-happening。核心意思：“AI 主导的认知工作危机”。 1. 《Something Big Is Happening》中描述的硅谷“AI大灾变”是一种针对服务业白领的叙事，而中国的AI发展主线则是工业制造和特定的内容创作生态，两者的本质差异决定了不能套用。 参考资料 一件大事正在发生：https://shumer.dev/something-big-is-happening 推荐阅读： 谷歌提示工程白皮书｜Google Prompt Engineering
