Bradford Morgan White has published an excellent retrospective of QNX, the realtime microkernel operating system focused on embedded use cases. The final paragraph made me sad, though.
QNX is a fascinating operating system. It was extremely well designed from the start, and while it has been rewritten, the core ideas that allowed it survive for 45 years persist to this day. While I am sad that Photon was deprecated, the reasoning is sound. Most vendors using QNX either do not require a GUI, or they implement their own. For example, while Boston Dynamics uses QNX in their robots, they don’t really need Photon, and neither do SpaceX’s Falcon rockets. While cars certainly have displays, most vehicle makers desire their screen interfaces to have a unique look and feel. Of course, just stating these use cases of robots, rockets, and cars speaks to the incredible reliability and versatility of QNX. Better operating systems are possible, and QNX proves it.

Way back in 2004, before I even joined OSNews properly, I wrote about QNX as a desktop operating system, because back then I went through a short stint where I used QNX and its amazing Photon MicroGUI as my primary desktop. Back then, there was a short-lived but very enthusiastic community using QNX on desktops, sharing tips and findings, supported by one or two QNX employees who tried their best to support this fledgling community in the face of corporate indifference.
Eventually, these QNX employees left the company, and QNX started making it clearer than ever that they were not, in any way, interested in people using QNX on desktops, and in all honesty, they were most likely correct. However, I still think we had something special there, and had QNX’ management decided to help us out, it could’ve grown into something more sustainable. An open source QNX and Photon could’ve had an impact.
Using QNX on the desktop back then was much easier than you might imagine, with graphical package managers, capable browsers and email clients, a massive pile of open source packages, pretty great performance, and little to no need to ever leave the GUI and use a CLI. If your hardware was properly supported, you could have a great experience.
One of the very small “what-ifs” form the early 2000s.
I still have my Blackberry Playbook (it ran QNX.) What a cool little device that was. I played many hours of Plants vs. Zombies and Machinarium on that thing.
