One of the most shameful moments of my career happened on the Saturday night before WWDC in 2010. I'd never worked on a system with more than one component or more than 20,000 lines of code. Drunk, I managed to stumble from Jeff's hot-tub to his roof and told him that Twitter's scaling problems were "stupid" and that "there were no good reasons why Twitter should go down".

I've apologized to him before, but after having worked on Minefold for the last 2 years, I feel like I need to apologize again. The work that Jeff and the others at Twitter have done has been amazing. I was also a massive cock.
