Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

| Hi everyone, I'm Chris Wanstrath. | |
| When Jeremy asked me to come talk, I said yes. Hell yes. Immediately. But | |
| then I took a few moments and thought, Wait, why? Why me? What am I supposed | |
| to say that's interesting? Something about Ruby, perhaps. Maybe the | |
| future of it. The future of something, at least. That sounds | |
| keynote-y. |
| Jeremy | |
| Absolutely brilliant | |
| both technically | |
| and oratorically | |

| Building & engineering around startup uncertainty - Mike Krieger | |
| [Slides] | |
| Confusion sinks startups, so we need to fight it. First thing that needs to be handled is the product itself, and what needs to be built. The second part is the technical challenges that happen with building said product. | |
| Instagram came out of a project called burbn. It was an HTML5 app that did social/mobile/location stuff. The most asked question was “what are you guys?” You have to actually focus on something. And it took them three months to get less confused. | |
| They did this by doing four things: | |
| ideate |
| upstream manager { | |
| # fail_timeout=0 means we always retry an upstream even if it failed | |
| # to return a good HTTP response (in case the Unicorn master nukes a | |
| # single worker for timing out). | |
| server unix:/opt/x.com/manager/current/tmp/sockets/unicorn.sock fail_timeout=0; | |
| } | |
| server { | |
| listen 80; |
