Fun idea, but your auth is quite broken right now. I keep losing my work; very frustrating. Also, already lost my work on one challenge from clicking the I/O button.<p>I like the cool 80s nostalgia, but it's not super-usable.
The idea is fun but it's really not user friendly at all. I spent like 10 minutes in order to find out how to edit the examples, save them and run them.<p>I'm not a vi user so I had trouble knowing how to use :w and :q. Also, what's up with the big I/O button that does nothing?
It took >5 seconds to respond to my ls command, and then the first time I typed a challenge name nothing happened. I sat there waiting for something to happen, and then eventually typed it again (I tried to tab-complete and highlighted my address bar) and it asked for my authorization, even though I had just authorized two minutes earlier. That was when I quit.<p>I would focus on making it more user-friendly before making new challenges.
Quite fun, but a task like md5 is an obvious "google, copy, paste". Even with normal editor and without any stability issues (I was asked to "auth" multiple times) it is a very complex algorithm.
This is throwing js errors in the console in Chrome. Can't save. Doesn't remember github auth. What the heck is the i/o button supposed to be? All it does it wipe out whatever I'm working on. Can't save with :w, probably related to the js errors.
They could have offered some real problems instead of standard exhausted algorithms. I don't feel the least compelled to compete knowing that thousands of variations of the code are available in 2 clicks.
Fun, but a little too tough to navigate for my liking. A SSH session would be a lot cooler than interacting with my web browser. Not sure how feasible this is.
