Be Judged...And Like It!

I recently ran across a fantastic way to waste some time in a completely productive manner. The Sphere Online Judge works like this:

1. You choose from a wide array of problems (think back to your computer science classes)


2. You develop and upload a solution in the language of your choice


3. Your code is run and judged against the time and memory constraints of the problem


4. If you pass, you get a warm fuzzy feeling inside. If you fail, you get angry and vow upon the graves of your forefathers to spend every waking moment figuring out how to find all the prime numbers between two given numbers up to 1 billion in under 6 seconds...not that anything like that happened to me.

I think this is a great way to keep your programming skills sharp and have some fun too.
