“Much of the core code on the site dated back to 2009-2010 and was written by Past Me, a vindictive, inscrutable nemesis who devoted his life to sabotaging Present Me.
Doing this on a live system is like performing kidney transplants on a playing mariachi band. The best case is that no one notices a change in the music; you chloroform the players one at a time and try to keep a steady hand while the band plays on. The worst case scenario is that the music stops and there is no way to unfix what you broke, just an angry mob. It is very scary.”
–Maciej Cegłowski “Pinboard is Eleven“
