Is gun violence an epidemic in the U.S.? Experts and history say it is
Destinee Adams, Production Assistant - npr

Linux Kernel：Page Fault 頁異常全面解析
當程序訪問虛擬內存中的一個頁面時，如果該頁面當前不在物理內存中，就會觸發一個稱爲 “page fault”（頁異常）的異常。操作系統需要處理這個異常，並將所需頁面從磁盤加載到內存中。實現虛存管理的一個關鍵是 page fault 異常處理，其過程中主要涉及到函數 — dopgfault 的具體實現。比如，在程序的執行過程中由於某種原因（頁框不存在 / 寫只讀頁等）而使 CPU 無法最終訪問到相應的 ⌘ Read more
