Hi! I'm Jeff. Nice to meet you.
I am currently an engineer at Google (Maps for Android) in Mountain View, CA, though my opinions and advice are my own.
Though I like helping with any answers I can, I am found most often on StackOverflow. I particularly like helping debug and explain Guice and Mockito, which I count as two of the most-powerful (and sometimes least-intuitive) packages available in Java today.
My five favorite computer science inventions: Code-generating serialization layers (Protocol Buffers and Thrift), Bloom filters, Hilbert indexes, A* search, and CompactHashSet. I'm also a fan of DI and mocking frameworks, as you can see above. :)
