This weekend was Hackcamp London 2010. 80 or so geeks camped out in Google London’s canteen building stuff. We all came filled with ideas and had 24 hours to make them work.

The day kicked off with a range of presentations running us through various APIs that we might liked to have worked with. There were a wide range of different APIs demoed all giving us more ideas about what we could build.

• Ade Oshineye – Buzz
• @themattharris Matt Harris – Twitter
• Oliver Ogg – GigJunkie
• Nick Johnson – AppEngine
• Michael Mahemoff – Chrome/HTML5
• Thong Nguyen – mFlow music APIs
• Reinier Zwitserloot – Safari Extensions
• Tim Nash – United Nations World Food Program

Hack prizes were announced including a prize for the best sandwich hack.

This is only the second hackday I’ve been too and I am really not much of a coder but I still managed to arrive with way too many ideas of what to build. Most of my ideas had started with a small idea and by the time I arrived into London on Saturday morning had mutated into gigantic ideas that would have been too much to make in a weekend even if I knew how.

So I built a twitter sentiment analysis app. It’s not 100% accurate and is still a bit buggy but I learnt a lot doing it and don’t think it’s bad for 24 hours work. I plan on working on it more in future as at the moment it is not as sophisticated as it could be. But like I said we had 24 hours.
