Selected upstream contributions — googletest, cctz, double-conversion, the Bazel ecosystem, DefinitelyTyped, huggingface_hub, Google Closure Library, the official Go Blog, and webapp2 — the web framework bundled in Google App Engine's Python runtime, where I'm an AUTHORS-listed contributor. A change to Vim — adding *.BUILD and *.bazel filetype detection — was applied by Vim's creator Bram Moolenaar himself as patch 8.2.1566 (2020), and later ported into Neovim, where it ships in the core filetype detection today. Earlier still, a patch to GetGnuWin32 (2005) earned a line in its acknowledgments. And python-rsa — multi-core key generation, early Python 3 compatibility, and a ~15× faster integer-to-bytes path, credited by name in the project changelog. The thread runs all the way back to my first release — WebView XP (2002), a Windows XP–style Explorer task pane for Windows 98/Me/2000, published as open source under my early alias Art Sands — and to the Win32 ASM Community (archived), where, as art_sands (2003), I proposed and co-authored an open, editable wikibook on x86 assembly programming.
