I’m not really going to address the speaker directly since after reading NSF forums for a few years, I’m convinced aerospace engineers can devolve any innocent or academic discussion into 4chan levels at rates exceeding the speed of light. Of note: the speaker doesn’t speak to anything specific that is being worked on to address issues, and only addresses “linux” as a whole, which is about as useful as addressing SVR4 as a whole.

I will address the blog writer as not being particularly diligent in filling that gap, though. Here’s a few links of what’s going on in that realm since there’s people here of all walks and ages:

Wind River RTLinux

Zephyr Project

OSADL SIL2LinuxMP

Xenomai
