Journaling Bits

摘要

My typical work day is filled with interruptions. Phones constantly ringing; people asking questions, etc. Everyone wants a piece of my time. Interruptions are not only a major hit to productivity and effective time management; but when you're trying to replace a PowerBook logic board, it can mean bigger problems. They sometimes leave me wondering, "Where did I set my screwdriver?", or "Where does this screw go again?" Now imagine having a secretary that follows you around all day recording what you do. Whenever you finish a task, it is scratched off a list; and whenever you start a new task, it is added to a list. Anytime you had an interruption, you could simply ask your secretary what you were doing before the interruption. That would be amazing! This is what Apple's software engineer's were thinking when they introduced file system journaling.
