message: Isn't Mac OS X the most succesful microkernel-based OS nowadays? Can someone provide sales figures? Qwertyus 15:55, 4 May 2006 (UTC)
thread_title:  Most successful microkernel operating system? 

message: "Despite these efforts, direct comparisons between QNX being one of the fastest microkernel systems available and monolithic systems like Linux indicate that the microkernel concept cannot provide the same performance." was added by . and "QNX is addressing some of these issues by limiting the use of IRQ usage and use hardware polling where possible to decrease the number of task switches." doesn't seem quite right.  Without a cite, there's an NPOV issue. Does anyone have a cite for that?   --John Nagle 01:15, 31 May 2006 (UTC)
replies: text: I deleted the whole paragraph.  There has been no verification of the claims, and nobody has argued here on the talk page that those claims should stay in.  62.214.228.219 also never even specified precisely what was meant by "performance".  If someone feels like rewriting the claims to better fit into the article, and can provide some reference to back them up, I for one don't have any problems with it though.  -- magetoo 16:33, 21 January 2007 (UTC)

message: The "Unix-like operating system" template at the bottom of the page lists QNX as a Unix-like system. But the Infobox says "OS family: 	Not Applicable". Is QNX an Unix-like operating system? I am confused...
: QNX has a UNIX-like API (QNX 6 is POSIX-compliant), and most UNIX or Linux text-mode programs will work on QNX if recompiled, but underneath, the system is totally different. So that info is essentially correct.  --John Nagle 16:28, 3 September 2006 (UTC)

message: "open source for non-commercial use" as the intro states is an oxymoron. What are the real license terms for QNX these days? --Ævar Arnfjörð Bjarmason 16:21, 12 September 2007 (UTC)
replies: text: Agreed.  It sounds like they've published the source code, but under a non-commercial license, which does not conform to the Open Source Definition.  I suggest change "open source" to "source available for non-commercial use". fraggle 08:17, 13 September 2007 (UTC)

message: I remember that in the late 1990s QNX would ship with a bag of President's Choice chocolate chip cookies to eat while it installed.  A cursory net search doesn't turn up any supporting evidence of this, and I'm hesitant to add this detail based on personal experience alone.  Can somebody add a reference for this? 99.233.162.32 (talk) 12:04, 8 July 2009 (UTC)
thread_title:  Chocolate Chip Cookies 

message: According to http://www.qnx.com/developers/docs/6.4.1/neutrino/sys_arch/intro.html "The first version of the QNX OS was shipped in 1981.". I am 99% sure that there should be 1981.

thread_title:  Initial release 1982, is this correct ? 

message: Hello. I am compiling information regarding QNX release history at User:Trollaxor/QNX_release_history. It seems that QSS does not keep old press releases (or may never have issued any) and, due to the marginal nature of this operating system, it receives very little attention in mainstream press. I therefore ask that anyone with sources for release dates—not only press releases, but also reports from reputable magazines, web sites, QNX doucmentation, etc.—either edit the my list or leave a message for me at my talk page. Thank you. Trollaxor (talk) 06:07, 9 May 2010 (UTC)
thread_title:  QNX Release History 

message: I remember back when QNX was called QUINX and there was a naming dispute in using the word UNIX in their product/Company name.  It wasn't named QUNIX for very long before the name change to QNX.  I'm sure I could find some reference to it in my old BYTE magazines.  Google now has the entire print editions of PC Magazine online.  The very first issue has an ad for QUINX on page 69.  — Preceding unsigned comment added by Jaytaylormn (talk • contribs) 01:39, 3 October 2011 (UTC)
thread_title:  QNX Name History 

message: In the late 1980s I was the sole software provider for a company (optimistically) called "Data Check International." A Data Check system had a central computer, an IBM PC or clone, with a number of terminals for data entry and editing, and a connection for one or more phone lines on which merchants sent queries on customers by means of CATs (credit authorization terminals--those now-ubiquitous credit/debit card scanners). Early versions of the Data Check software on MS-DOS and UNIX did not provide stable operation. In 1988 I converted the software to run on QNX 2.1, and within a few months I had a stable software system. The big advantage of QNX, besides its stability, was that it was networking and multi-tasking right out of the box. And it was fast--very fast. I still have my QNX C Compiler manual, which has "© 1982,1988 Quantum Software Systems Ltd." on the title page verso. (That doesn't mean that QNX came out in 1982, only that the C Compiler did.) In 1991 I worked for six months in Phoenix with a software team developing the "Roomfinder III" system for Ramada Inns Inc. The Roomfinder software was to run at each "property" (their term for motels, a "forbidden" word for us to use), communicating with a central server on a mainframe. Management had selected QNX as the best OS to use for this software. From what I saw, it worked beautifully. I haven't used QNX for some 20 years now (I stopped programming when everything went GUI), but I still remember it as the best OS I ever used. I never saw QNX 2.1 crash--not even once.
