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.
| # The fact that YAML.load will instantiate arbitrary ruby objects | |
| # means that calling `YAML.load` on untrusted data is virtually always | |
| # equivalent to executing arbitrary code in a complex app. | |
| # This code fragment globally neuters YAML to disable this behavior, | |
| # which should (hopefully) cut off all such attacks from the start. | |
| # I don't promise this closes all possible attacks, but this closes | |
| # off the trivial case. You should audit and upgrade all your | |
| # dependencies, as well. |
