Someone already blogged about my Guice talk:
Guice。一个Java依赖注入工具库。以前看了一些介绍，没看明白，今天一听还是明白了一些，这个东西很巧妙，看起来很优雅。演讲者就是创建人，crazybob。非常的年轻，期间提了几个问题诸如多少人用过Mock对象做UT，多少人了解Annotation等，应者寥寥。看了国内Java程序员的整体水平还不是太高。The attendees yesterday were very passionate and excited. It was as exhausting as any conference but well worth it.
I suppose the Google Developer Day in Mountain View is going on as we speak. You can still catch the live streams of the last sessions.
