Open Source Contributions

Patches merged into repositories I do not own. 29 pull requests across 19 organizations that are not mine, plus 91 issues filed into roughly 45 upstream projects, the first merged when I was 12.

Maintaining in the other direction: 69 issues opened on my projects by other people and answered, and 19 of 22 outside contributors' pull requests reviewed and merged. MobChip took 13 of those at a 100% merge rate; when I stopped maintaining it, its most active outside contributor forked it as MobChipLite and still ships it today.
