Let's go code-golfing again! Only this time, we won't know the best possible score ahead of time, so groups will actually be competing against each other. There will be some sort of reward for winning each "hole". Probably candy. ... It's going to be candy.
Bring your laptops. Have them ready to run Ruby 2.0.
What is code golf?
Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible code that implements a certain algorithm.
In other words, each group will attempt to solve a provided problem using the fewest number of characters possible.
This can result in some really ugly code, but it often also results in learning something about the language.
AAAAACH! I am just a beginner! This sounds scary!
I think this will be invaluable for beginners. At our last code golf hack night, teams were well-mixed with experts and beginners alike. The experts took time to explain various techniques they were using to solve the problem, and to whittle down the number of characters used. Experts often also took some time to explain _other_ implementations as they were shown. (Experts: please keep doing that stuff!)
Please don't be scared. It'll be low pressure. At the least, eat some pizza and observe the game.
