Every problem in NP can be reduced to the satisfiability problem, which is the cornerstone of computational complexity theory.

你无法控制一切。有时候你只需要放松，相信事情会好起来的。稍微放手，让生活自然发生。

我不是那种会让对旅程的爱减少的人。

I think frugality drives innovation， just like other constraints do. One of the only ways to get out of a tight box is to invent your way out.
