Boring for the Whole Day




From Thursday till now I am just keep wasting time. The homework for Types and Programming Languages is due to Thursday of nextweek, but I didn't have a little desire to accomplish it. After defining the syntax and judgment, I found something hard to understand and difficult to implement. After thinking on it for a couple of hours, I feel tired and give up. And now, it's hard to repick them.
