CHANCES ARE PRETTY GOOD that you are not developing software at work that fulfills your most ambitious software development daydreams.
The harder you work on an open source project, the faster you'll realize your true ambitions as a programmer.
Open source provides enormous opportunities for the motivated programmer.
If you want to get involved, you could offer to help out with the documentation. Or you could start by volunteering to write test code.
Write test code, really good test code. Find bugs, suggest fixes, make friends, work on software you like, and fulfill your software development ambitions.
