QNX is now free for anything non-commercial, plus there's an RPi image

20 years too late but ok.

For anyone who (like me) was confused at what this is, it's a Unix like OS for embedded systems.

I’d love to see this. I’m curious about QNX but at a loss as to how it could benefit me as someone who tinkers with robotics at home.

I also work for a non-profit org which does coastal margin research. We have several people working on custom hardware. Could this benefit us?

My previous company, which made high-availability (Active/Standby) routers for mobile networks, used QNX as the OS. I remain impressed by its capabilities.

My memory is rusty, but we ran QNX on the control-plane processors, and it natively allowed launching processes on remote processors over the internal network of the router. That is: their low-level IPC was IP-capable. QNX's IPC was essential for our HA failover functionality.

Also, device drivers as user-space processes that you could restart on crash was great (we were developing our network drivers, so this would occasionally happen). Also, better respect for devices actually showing up in the /dev/ tree, unlike Linux where network devices are a notable exception.

One funny story, I once spent days debugging an issue which turned out to be due to me accidentally marking const the return values of some IPC, which caused my process to crash in between QNX's IPC function and mine! Whatever level of debugger (C/userspace) I was using at the time could not catch the error ^^;

For attracting more developers can you compile a comarison table with the benefits of QNX versus competitors?

The existing information out there is of questionable reliability and probably out of date too...
