15 years ago Rob set out to replace all the gnu packages in Linux From Scratch with alternatives like BusyBox, and spent so much time upgrading BusyBox he was appointed maintainer of that project. Ten years ago he left busybox and started over with toybox, and last year toybox was merged into the Android M base operating system. He's currently working to turn Android into a development environment capable of building itself under itself. Along the way he got involved in j-core.org (a BSD-licensed open source clean room clone of the SuperH processor architecture made possible by expiring patents), spent a couple years maintaining the kernel's Documentation directory and kernel.org/doc. Video of him throwing liquid nitrogen into a swimming pool (at a combination linux expo and science fiction convention he'd co-foundeded) has been viewed on Youtube 11 million times.
