sharpen the saw

Today I got my feature done in an hour, but I spent 3 hours wrestling Spring, JBOSS, and Eclipse.

I would just like to restate some of my principles now.

* Tool performance and stability is important.
* Iteration time is important.
* A good error message can save an hour of time.

Which is to say, if you pay someone $40 an hour, you should buy them a $400 tool if it saves them 10 hours of time over it's lifetime.
