Stupid until proven otherwise

Feels like a life time ago, I was in the architect’s seat for a multi-million dollar proposed project. From my perspective I made several really damning design choices that I can only argue originated from my lack of more experience. Regardless of these mistakes, the team lead and the other code monkeys got the project off the floor and handling several thousands of concurrent requests/second without to much pain and suffering. So in the grand scheme I suppose the whole thing could be check on the plus column as a success.

Still, years later, my biggest mistake was abusing the crap out of data hiding in the form of protected/private parameters, guarded methods, and such… all because I didn’t trust the junior and mid-level dev’s to get it right. Because of these somewhat draconian design, the natural result was that the code monkeys worked around my restrictions at the cost of precious CPU cycles, extra memory, and some truly horrendous hacks. Sure as the architect I should have caught all of these things, but by that time I had become overbooked as lead on more critical projects while also being the acting DBA and sys. admin for everything ( except the obligatory exchange server which I successfully pretended didn’t exist ).

Thinking over how I would have handled things better, I think the over-arching gist of Alex Martelli’s presentation on API Anti-patterns from PyCon 2011 – http://vodpod.com/watch/5757194-pycon-2011-api-design-anti-patterns
