The responses are typically "do programming challenges", "contribute to an open source project", or "make a game."

Learn how to generate binaural beats using Java. A binaural beat is an auditory illusion perceived when two different pure-tone sine waves are heard dichotically, that is one through each ear. For example, if you wear a pair of headphones and one side is playing a 440Hz tone and the other side is playing a 450Hz tone you will actually hear a third tone that is the difference of the two frequencies. Your brain will interpret the difference between 440Hz and 450Hz and you will hear a third tone of 10Hz.
