One time I tried to change a column name in a production database. I learned that when you change a column name, mysql doesn't just change a string somewhere, it creates a new table and copies all the values from the old table into the new one and when that table has millions of rows in it, it really slows down your production server.

This is dead on. Another developer and my self reluctantly joined our office's league this year, despite knowing nothing about football. We're both dominating. He's 7-1 and I'm 6-2. I'd be 7-1 too if I'd have known what a 'bye' week was and paid closer attention to my team.

The spoke design is pretty clever, but isn't the real problem is going to be the tire? I can't think of any material that would be durable enough for those conditions and flexible enough to change shape with the spokes.
