I'm happy to announce that the data loss bug has finally
been fixed. (It was fixed last Thursday, actually).
Your files shouldn't disappear anymore.
However, it's probably still a good idea to at least print
your code everytime you have something working.
Sorry for all the inconvenience this bug has cost you :(
If any of you experience any more data loss, please
inform us (6.096-staff@mit.edu) ASAP.
Happy coding!
