There should be a retweet on HN!
QNX was one the most impressive OS I've seen, especially for its time. From the full OS in a 1.44Mb floppy disk to restartable drivers, real-time, etc. IPC with messages is built in and most things ran in userland.
It ended in the hands of BlackBerry which is probably not the best home for it...
Edit: I googled out of curiosity, and despite being closed source, it seems to still be marketed by BlackBerry and is supposedly a market leader in embedded OSes! More than 20 years later, well deserved.

- Cyph0n 5y agoMost of Cisco's high-end service provider routers were running IOS-XR on top of QNX. They switched from QNX to a Linux kernel (specifically, Wind River) around 7 years back.
- rubylark 5y agoQNX is still going strong even with Blackberry. I worked at a company recently that heavily relied on QNX for safety critical embedded OS projects. It's Qt and QML integration made rapid prototyping a snap. Unfortunately it requires pretty (relatively) hefty processors so I never personally got to use it.
- detaro 5y agoYes, it's still around. Sadly nowadays feels a bit neglected, and isn't quite keeping up. They have their markets that have little other choices and/or are very conservative in switching to something else, and will live of those for quite a while.
