Erik owns two tuxscreen phones. After the first month or so, he decided to actually do something useful, so he created the BuildRoot system that is being use to build the software for the tuxscreen.
In order to make the BuildRoot system work without needing root permission, Erik rewrote large portions of mkfs.jffs2 and jffs2reader. Furthermore, since Erik maintains BusyBox, TinyLogin, and uClibc, he has ended up pretty involved in the effort to make the tuxscreen work.
Erik can be found at http://codepoet.org/ where he hacks away late into the night.
