Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

In the fine tradition of Nachos and Pintos! (Still waiting on Burritos - which would obviously have to be based on functional programming principles - and Churros.)

Burritos are just monoids in the category of endotacos.

I'd just like to interject for a moment. What you're refering to as Burritos, is in fact, GNU/Burritos, or as I've recently taken to calling it, GNU plus Burritos. Burritos is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
