openqnx

The 17-year-old sources of QNX (to be found at github.com/vocho/openqnx) don't have a clearly-defined license file/status. In theory, one can use them, experiment with them, but they're neither free-, nor completely open-source. Does it make sense to ask QSS/Blackberry to re-license them under e.g. Apache 2.0 license -- the same license they use for their startup code sources? If yes, does it make sense to write/publish an open petition?

Nice article, interesting read. The Neutrino 6.4 version, which was made accessible as "openQNX" to the public, can still be downloaded from e.g. https://github.com/vocho/openqnx. Here is an AI generated documentation of the source: https://deepwiki.com/vocho/openqnx

I found this a while back. Unsure if it's related https://github.com/vocho/openqnx (I prefer 32-bit because most applications don't need more than 4GB RAM, but I guess 64-bit could be useful too)

no, it never was. the qnx source code was available, but it wasn't under an open-source license. if it were, given the number of fans it had in its heyday, there'd be at least one live qnx fork https://github.com/vocho/openqnx/blob/master/trunk/lib/c/1/o... quotes the license as follows > You must obtain a written license from and pay applicable license fees to QNX Software Systems before you may reproduce, modify or distribute this software, or any work that includes all or part of this software. Free development licenses are available for evaluation and non-commercial purposes. For more information visit http://licensing.qnx.com or email licensing@qnx.com.

replying to your old message [1]. The openqnx monartis source code is on github: https://github.com/vocho/openqnx [1] https://news.ycombinator.com/item?id=26255095

I don't have numbers, but the key ingredient is really minimizing context switches. This also results in priority inheritance while message passing which means that a high priority process gets the answer with it's own high priority, even if sending a message to a low priority process. Very smart. Teading the old open sourced sources can be quite interesting... https://github.com/vocho/openqnx/tree/master/trunk/lib/qnx43...
