The Rise Of QNX
QNX might not be new, but SirTimbly is right about it making a stir. Max von H. writes: "Audrey, the household net appliance from 3Com/ergo has been officially released, and there's even an official site on which you can smile at the design. The beast runs QNX/Neutrino, as stated in this ZDNet story. The sweet thing is it can sync with two PalmOS devices, which can make a geek couple's life much easier without having to fumble with a real PC. Say what you want, but Audrey could possibly be successful since anybody can use it, and 3Com has shown a simple system rules when it comes to do simple things."
And no mention of QNX is complete without a reference to the QNX demo disk, which packs a pretty amazing set of features onto a floppy. Here too, it's free, but not Free.
Firstly, QNX is pronounced Queue-nicks, not Queue-nucks.
Secondly, it was developed at the University of Waterloo in Ontario, Canada and then spun off into a company.
Thirdly, it is not *just* an embedded OS, its most prominant use (atleast to Ontario and Quebec elemenrtary and secondary school students some 10 years ago) was on the PC powering that evil Unisys companies line of diskless 80186 based network computers called the Icon of which our schools had ungodly amounts of. QNX is also used quite extensively in the Canadian Armed Forces and can be used as a desktop OS.

QNX was NOT developped by 3com, and I quote: &The Ontario, Canada-based company was founded 20 years ago as a real-time operating system vendor."
At least get you facts straight and make it look like you actually read and understood the article before you post.
I also gave it a try. I downloaded the ISO image, burned it, booted it, installed it, and I must say - the install was flawless. The photon microgui is not X-based and is very fast. The OS itself is also very fast. I may use the floppy demo to setup an internet terminal on my LAN. I have to agree with you regarding the confusing file system layout.
You mentioned BeOS only now getting support from vendors and this is in fact mentioned on benews.com or one of the other beos sites. I am impressed with qnx overall as it has been a good embedded OS for many years now. It probably has more viability controlling robots in a high tech assembly plant than as a full blown desktop OS though. We'll just have to wait and see what comes of it.
In 1982, I ported one of the earliest MUDS (Scepter, 1979) from a Cyber 6000 mainframe to a PC using QNX. It supported sixteen users on an IBM PC XT (4Mhz 8-bit 8088 CPU). And no stinking 16650 FIFOs. With 1-character-per-interrupt, 16 users merrily MUD'ed away at 2400 baud.
In addition to the MUD we offered chat rooms, e-mail, and two other multi-player games (Diplomacy and Space Combat). We charged $2.99 an hour. It paid my way through college.
Don't believe it? Telnet to drscape.com. To this day it still runs on a 4Mhz PC XT with QNX 1.14.

No one has mentioned the coolest things about QNX -- notably its architecture. QNX is a highly reliable, real-time OS based on message passing. It really is a microkernel OS. Even device and filesystem drivers run in userspace. This makes it incredibly stable, as you can actually crash a driver, restart it, and keep going. You can also upgrade subsystems without taking the machine offline. QNX is used in systems that cannot fail, such as heart monitors.
It's also really efficiently written, and almost completely modular (as opposed to Linux' monolithic-plus-kitchen-sink approach). Their 1.44MB Floppy demo contains the bootloader and kernel, a GUI, a web wrowser, tcp/ip and PPP. No other OS can do that, because they're too bloated. Linux can be put in a floppy, but there's no way to fit a GUI and a web browser as well. YOu might be able to chuck out things like the shell and libc, and include a statically-linked version of lynx, but nothing as good as the QNX demo can be achieved.
QNX is much more suitable for PDAs and otehr small systems than is Linux. It's loads more reliable, more easily upgradable, and much more compact. Just look at the iOpener; into 16MB they fit the OS, a custom GUI built on top of the QNX GUI, web browser, email, telnet server, and other things, and hadspace left over to store files. The only other OS that could do that is WinCE, and it's much more limited than QNX (such as a limit of 32 processes, 22 of which are consumed by the system itself).
QNX rocks!

I'm sure that when I tried out QNX RTP it had GNU development tools (gcc etc.) with it. There's also a largr number of everyone's fav. Linux apps ported..
I tried out RTP when it came out, they had ports for (but not limited to)
- gtk
- x11amp
- gimp
- ssh
- mc
- vi
- (maybe emacs..)
- abiword
- a Mozilla port that I couldn't find
- many, many others.
Overall, the OS was smokin' fast, they're going to be using IBM's JDK (actually developed in Ottawa too by one of the object* companies.) They also had good 3D support for my Voodoo 3, and had demos of Q3 to prove it..
The browser was pretty good, the photon interface was good (but not as nice as the DE's for Linux.) Anyway, I was quite imoressed. Maybe you should give it a spin...

It's NOT LINUX!!
It's good to have choice. That's why we have a bazillion window managers and theming skinnable apps that give you a billion ways to dump core. >:(
But aside from the bland "choice is good" mantra, QNX has definite good qualities of its own - it's very lightweight, very fast, has a decent GUI system going for it (despite not having DND, which I deem a semi-serious flaw, but one that could be tackled), and it could teach other people a thing or two yet with the way it does stuff. And even if it doesn't even have anything to teach, it's still a potentially very useful OS to run on one's computer. Time will tell. Time and apps.
Don't dump on it (yet).
GAIN EVERLASTING LIFE!
