The related ongoing merged thread is Bob Lee, former CTO of Square, has died after being stabbed in San Francisco - https://news.ycombinator.com/item?id=35448899. I've converted aEJ04Izw5HYm's comment from that thread into this top-level submission so that comments and memories about Bob Lee can have a place of their own.
As for discussion of the event itself, (1) please keep it in the other thread, not this one; and (2) please don't go off the flamewar deep end when you do. The worst stuff in that thread is pretty bad and not at all in the intended spirit of this site: https://news.ycombinator.com/newsguidelines.html.
Edit: I've gone through that thread now and tried to move all the relevant comments here. If you notice a good comment about Bob Lee languishing in another thread, let us know (hn@ycombinator.com is best) and we'll bring it over.
