乔布斯之所以否决一台触控 Mac,其实是因为他想得会更深远一点:如果要为 Mac 增加触控屏,那必须要围绕全新的「触控」交互,大改整个 Mac 的界面,进一步发挥触屏的价值,要不然就不加。
Lazy DFAs (2010) are a clever optimization to mitigate the O(2^m) blowup of DFA construction, by only constructing the states that you actually visit. lazy DFAs reduce the theoretical automata construction time to either O(2^m) or O(n), whichever is lower. you could argue that it’s theoretically no longer linear time, since you could have a regex that creates a new state for every character in the input, but in practice you will keep revisiting the same states. for all intents and purposes it behaves more like O(n) with some initial wind-up time. the main downside of lazy DFAs is that they are more complex to implement, and you have to ship a compiler as part of your regex algorithm. i want to highlight Rust regex and RE2 as excellent implementations of this approach, which you can also see in the benchmarks.,更多细节参见safew官方版本下载
