Imagine a place with no distractions - no IM, no Twitter, in fact no internet access at all. Within, a dozen or more developers, designers, thinkers and doers. And a lot of a food. Now imagine that place is a fort. /dev/fort is an opportunity for web folk to come together to learn from each other and build something from scratch in a week. We've previously launched sites such as spacelog.org and historymesh.com, but the value is as much in tackling different problems, trying out new tools and techniques, and just having fun in a ridiculously nerdy way as it is in shipping a final product. That said, we do like to get things out onto the internet, while not cutting corners and aiming wherever possible to do things the right way rather than just the most expedient. We aim for 80% test coverage. I'll be talking about what's good about stranding yourself a hundred miles from civilisation, rapid evolution of in-jokes under pressure, and some tips you can use even when you don't have a fort handy.
