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.

Hurd isn't exactly a useful project, but using Doom as the benchmark for the capability of an OS is a bit ridiculous.

Given that pregnancy tests can now run Doom, I have to agree with you. It was more of a symbolic thing than a technical difficulty at this point lol.

They can't, actually.

It runs on the screen of a pregnancy test, Doom is actually executed on an Arm Cortex M0+ based Adafruit Trinket.
