遇見新朋友，握手並且自我介紹的時候，除了名字，我們還應該如何介紹自己？
視乎場合吧，但大多數時候，最有效的方式就是介紹自己的職業。「我是當教師的。」很清楚，那不單代表你這個人對教育有熱
My new view of DomainKeys
Now that I actually understand how DKIM works ,I have a much better view of it than I used to and as a result it's much more attractive and likely to be implementedhere some day.

減酒
最近飲多了酒，被老婆投訴，所以決定減酒。人說戒酒，我說減酒，是因為知道自己不會做到滴酒不沾；說到底，飲酒始終是樂事。
