Besides background concerns about buildings burning down and people driving home drunk, I had three personal success conditions for Yahoo!'s first open hack day:
I'm very, very happy to say that all three were met. You could have gotten a sunburn off all the wireless that day; it was full-strength from one end of the lawn to the other, and even when I sat down in a classroom with 32 other people, all hitting the same little node all at once, it was fine.
Beck did indeed show up, as has been documented elsewhere. (The truly neat part was after the show, when he and the band came out and took a stroll through Hack Day; they were genuinely interested in what was happening, and our hackers were cool enough not to mob them.)
Oh, and we had about 56 outstanding hacks. Special props to:
One more thing and I'll quit, for now. Two of my friends, front-end guys Scott Schiller and Eric Wu, turned out early Friday to help register attendees, keep things running through the day, and (naturally) enjoy the Beck show later that evening. As it turned out, both of them wound up getting sucked into the full Hack Day experience. Eric helped the Mobile Blogging Platform hackers and Scott ran many of the same errands I did.
At the end of the day Saturday they both had tickets to the Download Festival, happening just up the road and starring our new best friend Beck. Scott, in case you don't know, is a huge Beck fan, so this didn't surprise me a bit. As it turned out, however, the Mobile Blogging Platform gang did not have tix for the show ... Eric had two extras ... there were three of them ... and Scott, gentleman that he is, gave his up, so the third MBP hacker could go to the show. Nice going, Scott.
