QRV Operating System: QNX on RISC-V
- ymz5 7mo agoThanks, chrsw! I encourage people to join the petition to re-license old QNX sources under Apache 2.0. If Blackberry does so, we'll have another good and free microkernel-based OS.
- jacquesm 7mo agoI spent a ton of time on trying to do just that years ago and it went nowhere, calibrate your hopes accordingly.
- wslh 7mo agoI checked out and BB revenue report [1] "driven by upbeat strength across its QNX division" (quote). I think this will make more difficult to obtain a QNX license if they don't see it strategic?

- jacquesm 7mo agoBB is a very traditional company, they're very much stuck in the 90's when it comes to software licensing. There is a BB QnX team member here on HN they can probably shine much more light on this than I can (but I realize they may not be free to talk about it).
- ahartmetz 7mo agoQNX is great. But please be more judicious with the AI writing. It's great at style transfer, so maybe tell it to write like Hemingway or something? He didn't use unnecessary words and repeat the always same "impactful" flourishes.
- ymz5 7mo agoWell, there's a plan in case BB doesn't re-license. We will rewrite the proprietary parts of the kernel from scratch. It's not trivial, but possible. We could use seL4 as a basis for the "core" message-passing primitives. Channels and connections will go next.
- jacquesm 7mo agoI've already done this. It's a thing one person can do in under a year.
