Today I have shipped my first ever open source library. It's so small and tiny that I am not sure it qualifies to be called a library, it doesn't even have a built script yet but it's definitely open and it's definitely shipped. It's out there on my github page. Meet SAXDVR. In my defense, it has a documentation page and it has unit tests. And it has a purpose.
The question at StackOverflow made me sit down and play with SAX filters. Couple hours into it and I had it working so I thought why not make one more step and put it out there. It felt great! Don't get me wrong, it will hardly be used by anybody other than as an illustration to my answer, but it did feel like a big deal to me. Ship!, doesn't matter small or large, and you will likely feel the same.
