Famous /prog/riders

We sure talk about programming a lot. But what is the most well-known software written (or at least worked on partially) by someone who posts here?

I wouldn’t expect any Bill Gates or Mark Zuckerberg tier person to be here, but at least some moderately well-known or successful person who has made a widely-used app/program/library.

Did Terry Davis ever post on /prog/? I guess he is sort of famous, but in a bad way. I hope there is a more positive example.

Its name is currently just "parseh.exe", and I haven't had any time in the past months to work on it (lots of IRL stuff.)

I know some of the suckless guys have posted here before.

If by "widely used" you mean "code that runs on almost every IBM PC-compatible made since 2004 or so at boot time..." ;)
