So sad. I met Bob once at an interview at Square in 2012 for the final interview. I believe he was the inventor of Google’s guice dependency injection library and the dagger library. I bombed the interview. I liked him anyway. RIP.
Before that I had even cold-emailed him about something related to the Square CC reader and he responded.
Anyway I didn't get the job either, but it was impossible not to like him in my very limited experience. Terribly tragic.
