Hurricane Sandy puts YAGNI to the test

On Sunday night, Oct 29th, we learned that most US equities markets would be closed the next day due to Hurricane Sandy.

Deploying With a Phone Call: Speech Recognition in a Java backend

November 11, 2011

We had a lot of fun playing with last week’s experiment.
