Two years ago to the day the most-viewed article was about A Hobby Kernel and User-Space, Runs Mesa and GCC. That hobbyist OS written from scratch seemed promising back then but hadn't heard anything at all since. When deciding to check on the project today I was anticipating that it had died off, but surprisingly, it's still under development.

ToaruOS remains under development and has been since late 2011. The most recent Git commits were from 11 days ago according to their GitHub site. For those that don't remember the article from two years ago, the Toaru kernel provides a Unix-like environment with some similarities to Linux but is written from scratch.

GCC provides the compiler support on the OS, Mesa is available to provide its software OpenGL implementation, and many software has been ported over including Cairo, FreeType, Vim, Lua, SDL, and more. If you want to learn more about the still-in-development ToaruOS, visit their GitHub site and/or The hardware support varies for ToaruOS but does appear to run fine within QEMU. Fun to see this hobbyist OS still being developed.
