Ayende just wrote an interesting post about the cost of maintaining fragile code:
You and I - I'm not pretending to be any better than everybody else on the subject - should fight the urge to keep unmaintainable code and never fear a rewrite even though it seems like wasted time. It's just so freakin' hard holding on to such a set of core values because it might cost features not being implemented in the short run... Know the feeling?
Anyway: What I wanted to really say was that I'm looking forward to hearing Ayende himself in at JAOO in Aarhus, Denmark. It's not every day you get to see one of the most influential people in the Open Source community in person so I'm quite excited about it :o)
