Tuesday we had our second ever "Vrolijke Framboos" (Dutch for Happy Raspberry) Java code challenge at JDriven and it was a blast! This year’s challenge was to create a REST service client that would play a number guessing game with the server. After setting up a session you would guess a number and the server would respond with either "lower", "higher" or "bingo". The goal was to guess as many numbers in the two minutes you’d be given. Given the name of the challenge you can probably guess that the target platform would be a Raspberry Pi!
