The most important part of all, which I didn’t get enough time to talk about at the conference, is that you don’t have to be a rocket scientist or hacker extraordinaire to contribute in a big way to an open source project you’re interested in. How do I know this, you may ask? Because I’m neither one of those things.
Sadly, I spent a lot of time on the outside looking in, thinking “I’d just be making trouble” or “I doubt I’d have any meaningful impact even if they did accept my submission”. If you tend to think on the same level, stop. Go fix a bug. Go write a test. Don’t let the fear of someone rejecting your submission stop you from trying in the first place.
