That night I met Julia (she and a friend were, if I remember correctly, trying to boot a handwritten kernel in a VM and figured it out around 11pm that only the first 300 bytes were getting loaded into memory).
I met Andrew Kelley, who had recently written an NES emulator that translated the code to LLVM (if I remember correctly).
I briefly met Filippo Valsorda. I think he was the person who, after I said I wanted to make a bitcoin arbitrage bot, immediately came up with putting the prices into a matrix and then computing optimal paths.
The place just seemed.. magical. I have a family and kids in Canada but i thought a long time about trying to reorient my life to NYC for a bit. It was just so cool.
It reminded me of the joy of learning for the sake of learning, hacking stuff because it feels like a magic superpower to bring ideas to life, and the joy of building things you have no intention on trying to make money off of.
I'm certain none of those people remember me but I remember the evening fondly whenever I see any of them show up on HN. Cheers :)
