New features include accelerated 3D, the Voyager 2 browser which supports HTML 4.01 and XHTML 1.1 now, SCTP (stream control transmission protocol) and packet filtering with NAT! GCC 3.3.1 is also included. If it's not a typo, the Professional version costs $8695/user o_O Usual QNX NC (non-commercial = free beer) LiveCD is not available on the download area yet (As of 9 Jun)... But it sounds very promising"

    Just FYI, that licensing cost is most likely a developer per-seat cost with some redistribution allowed.

    As far as per-user stuff, it's likely that most people use QNX in one form or another every day without knowing it. From cable boxes to ATMs, traffic lights, etc.

    QNX is put in places where failure cannot happen. At all.

      Not quite! QNX is a Soft Real Time Operating System - situations that need to fulfill "hard deadlines", for instance a medical monitoring device, will use a Hard Real Time Operating System.

      • Actually, QNX is a hard realtime system. Upper bounds are fixed and QNX is in fact used in many medical devices because of this behavior. Linux is a soft realtime system, since it can provide good response times but the upper bound is unlimited so it cannot assure those times when placed under load. The only real solution to this today is RTLinux.

        The paper in the first link is very weak on details, not surprising for a 300 level undergraduate course.

        • Is it sufficient for a system to be referred to as "hard real time" when the interrupt latency is provided? Some say that upper bounds on system calls need to be provided as well. This is not the case for QNX, is it?

    With 6.3.0 the download version of QNX will actually be our full commerical product, with downloads avaliable for both Windows, Solaris, Linux and Neutrino. After 30 days, these PE (pro edition) versions will turn into what was once the NC edition with the pro features disabled.

    I suspect the downloads will be up and ready very soon. You can find more details here:

    • I see!
      I'd be happy to use it :-)
      But I dont understand one thing: QNX is an OS, how do you (and QNX) mean that downloads will be available for Linux, Windows, Solaris, ...?
      • Not everyone develops for an OS under that OS. So we have cross development tools for targetting hardware running QNX that run under Solaris, Windows and Linux.

  • I am looking into some uses for embedded devices and was wondering if there was an affordable dev board that I could use to get my feet wet. All the boards I have seen are very expensive ($700+) which is just too much for me. Ebay hasn't been much help either.
    • You can get a used iPaq (36xx/37xx/38xx) on eBay very cheap, and you can have a good time hacking on it with QNX, Linux, Plan9, etc. It's a good and cheap ARM development platform.

Never say you know a man until you have divided an inheritance with him.
