And so if you are a bit of a geek and would like to play net/aces with this you can go to cs50.net/aces and I don't think Willie will give it to you to keep but you can borrow and play for some amount of time in exchange for some feedback on it.

所以，如果你有兴趣并想玩玩这个,那么你可以访问cs50。,但是我觉得Willie不会让你保管它,你可以去借，然后玩一段时间，但作为交换条件,你需要反馈一些意见。
