Qwen训练中优化QSA indexer top-k回放：原方案数据量达router百倍，每步耗时增8倍。作者发现中间环节无需理解top-k，改为payload只写一次存共享存储，仅传KB级引用，布局机器改用24字节handle，额外开销降至7%以下。

Locksmith是一个C#程序，可以快速识别和终止占用文件的进程。它可以用于解锁被不需要的进程占用的文件，例如在尝试删除文件时。该程序还可以识别占用文件夹的进程。这个功能对于弹出USB驱动器或删除文件等任务非常有用。

一个好的handle生成算法应满足需求，可以使用整数handle代替指针，使用自增id和hash表映射，避免碰撞，同时满足需求5，使用固定大小整数数组管理handle，回收时加一，避免重复分配，销毁handle时保证O(1)时间分配新handle，比自增方案更节省空间。若数组满可倍增size，但rehash过程复杂。使用该数据结构可将同类对象分配在一个大数组中，用handle索引，几乎没有额外开销。

Android音讯机制中的四大概念是ThreadLocal、MessageQueue、Looper和Handler。主线程不会因为Looper.loop()的死循环而卡死，而是因为长时间操作导致界面掉帧和ANR。子线程可以通过Handler、AsyncTask、LiveData和ViewModel等方式更新UI。Activity的生命周期是通过Android的音讯机制和Handler完成的。

Tomcat将请求委托给DispatcherServlet的doDispatch方法处理。doDispatch方法获取HandlerMapping和适配器，然后调用handle方法处理请求。handle方法通过模板方法调用RequestMappingHandlerAdapter的handleInternal方法处理请求，并返回ModelAndView对象。invokeHandlerMethod方法创建InvocableHandlerMethod对象，并调用invokeAndHandle方法处理请求。invokeAndHandle方法调用invokeForRequest方法，最终调用doInvoke方法处理请求。
