QNX 6.3 Released

Lufi2 writes "QNX 6.3 was released on 3 Jun. 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"

You don't have the slightest idea...

QNX is older than linux. It's a microkernel. It's realtime. Linux is neither. There was a very appropriate quote from somewhere - "Linux is what you trust your server to. QNX is what you trust your nuclear reactor to." They each have their place. -ReK

"QNX is what you trust your nuclear reactor to." Which would be rather stupid. From the license:

B3.2 High Risk. Unless QSS has provided its express written consent for each Runtime Component in the Runtime Configuration, the Software may not be, and OEM will ensure that it is not, used in any application in which the failure of the Software could lead to death, personal injury or severe physical or property damage (collectively, "High-Risk Applications"), including but not limited to the operation of nuclear facilities, mass transit systems, aircraft navigation or aircraft communication systems, air traffic control, weapon systems and direct life support machines. QSS expressly disclaims any express or implied warranty or condition of fitness for High-Risk Applications.

Nuclear sites, in the UK, do not rely on manufacturers warranties or pledges to maintain nuclear safety. Rather, they have in place their own systems of design, resting, certification and legal regulation. You can bet they use products whose manufacturers disclaim liability. What manufacturer wouldn't? However, in the UK, the government underwrites nuclear liabilities. In other words, it takes on the responsibility itself. It does not leave it to others i.e. to chance.

For example, a friend of mine once worked at a UK nuclear power station wher all the machines in the control room ran Solaris on SPARC hardware. It has a similar license clause to QNX. At my old powerstation we used all kids of stuff, from QNX to DOS, Windows 3.11, NT4, Solaris on SPARC, VMS on Microvax... you name it. Once again, it was horses for courses, and the liability was all underwritten by HM Government.

Stock Linux is neither. I personally know of at least one company [timesys.com] that offers a hard real-time [timesys.com] version of Linux.

ObDisclaimer: yes, I work for TimeSys.

Man, you're a troll. QNX2 came on 5.25" floppies in 1987 [levenez.com]. Here are some examples of some other things that happened in 1987:

• IBM introduced the fantastic new "VGA" graphics standard, blowing everyone away with its 256 colours of fury.
• Windows 2.0 [aci.com.pl] came out.

Surely you'll concede that QNX 2 is superior to Windows 2?

NC Download Changes

[variable]

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:

QNX 2.x? There was no GNU toolchain for QNX 2.x, so I strongly doubt you are using it.

QNX isn't Linux, our default /bin/sh is ksh not bash, although you can just fire up qnxinstall and go to the QNX Online repository and install bash. All my x86 workstation machines have bash installed with no trouble at all.

It would have been more informative if you had actually said what was broken with g++ rather then saying it was just broken. The only thing that is different from our 2.95.3 g++ vs. say Linux or BSD is that we have exceptions turned OFF by default instead of turned on. So you have to give the command line option for them to be enabled - "-fexceptions" I belive.

Real Time

[niker]

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.

Re:I don't get the attraction

[variable]

QNX isn't a Linux clone. QNX is a POSIX based OS that has a history that goes back a decade before Linux was even a glimmer in Linus's eye.

There is nothing given away for "free" either, there is an evaluation that is free - much the same as vmware has a 30 day eval of their product. After that 30 days, Neutrino will fall back into a more limited mode but will remain operational (like it was with NC before 6.3.0).
