WhoHack #3

2013-10-19 (Saturday) @ Rijeka, Croatia

It all started so innocent, like, we're going to organize a small (mini) hackathon for 25 folks and thought "no way we're gonna fill up half a room", we still don't have that community. We were also late with the website and public announcement, actually late for 2 weeks and in panic got the website up a week before the event. What happened then, not even 24 hours passed and the tickets were all gone; we haven't even shut down the registrations on time which got us additional 12 developers. We could of make a registration form disappear on 24th registration, but there was no time for that. So we just reserved the whole building floor and made up extra room, still a bit tidy.

When you organize events like this, there are always a set of unexpected events waiting for you in the worst possible time, and additionally find what else you forgot.

Day started with people waiting for us in front of the building, like an hour earlier which was a bit strange and unexpected. Developers are usually the night birds :) So the first few sit and suddenly PUFF, electricity went off! "no way we already lost power, that early?". Ok, on to the fuse box; with the elimination system we discovered it was a short in one of the power outlets. Finally over, NOT. A ton of Internet ports were closed on the city connection, so call one guy, then the other one, then email, then somebody calls us and then - finally, all ports open, in less than half an hour. We also had an alarm going off right when judges had a short private decision making discussion regarding the hackathon winners.

What to conclude out of all that was mentioned in the paragraph above? People collaborated to solve the electricity problem, they all shouted some port numbers they would want to use and laugh on the alarm. Freakin' awesome experience we'll all remember, it was perfect! :)

But most importantly. I Edi Budimilic, who attended hackathons from home all the way to Silicon Valley, I conclude that I've seen the biggest talent right here. We had 13 projects that were good enough for demonstration, not only that, but ten of them were ready for public use! The worst has happened, we had "only" 3 iPads, and all deserved it!

Teams were able to build a fully functional service in a single day, many of them built a website and even presentation for the end of the day. Looking at these presentations - we got the impression that we have some kind of Demo Day projects that were developed for months.

Hackathon theme was "improving society". It was necessary to make any kind of mobile application on any platform, which serves society in any way, not just locally. Some of the stringent criteria for participation in the prize pool were a good UX design, innovation and public use 'readiness'. Perhaps cause of that projects resulted in such great quality.

Complete gallery is here and on Facebook if you like liking and tagging people :)
