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!

A few months work by one guy and already more capable than the Hurd.

Imagine what you could accomplish given 35 years.

It is no way capable than Hurd. It is a cool project though. Have you used Hurd recently? It can run a modern desktop.

FWIW, GNU/Hurd has been able to run a desktop environment the last 20+ years.

And as someone who portedgor Doom working on GNU/Hurd decades ago … I’m going to wager that the GP has never used it. :-)
