The biggest thing I'm taking away from this blog post is that lousy interfaces and obscure failure modes really are inhibiting adoption of better computing practices. From the post:

if you’re like me, you will screw up at some point, leading to some problem, potentially catastrophic, that you will spend hours trying to figure out. I’m clearly not alone... “Abort: remote heads forked” anyone? :) At that point, we all just call over the one person in lab who knows how to deal with all this crap and hope for the best. And look, I’m relatively computer savvy, so I can only imagine how intimidating all this is for people who are less computer savvy.

I heard fewer complaints of this kind, and believe that I saw higher adoption rates, when we were teaching Subversion. I'm not going to recommend that we switch back, but I do miss it whenever I have to help someone deal with a detached head...

Thanks,
Greg
