Hello,
just FYI, I have set up a simple web page[1] to promote the wider microkernel community and its goals. So far, the page comes with a brief description of the microkernel concept and an incomplete list of microkernel projects with links to each project's web. The description is made out of the first two sentences I found in the "What is XYZ" section or elsewhere on the web of the respective project. I also took the freedom to use the respective project's logo (or what I believed was the project's logo) for promoting it.
I hope you will find this small web a good idea. It was inspired by a similar (though a little bit more informative) site set up by the unikernel community [2]. The sources of the [1] web are hosted on Github [3], so feel free to submit issues or PR to make the site better.
Please send me a PM if there are any issues pertaining your project's cartouche that cannot be dealt with using Github.
Thanks, Jakub

Interesting statement on the Muen kernel section: "The world’s first Open Source microkernel that has been formally proven to contain no runtime errors at the source code level. “
We proved full functional correctness (which is a superset of absence of runtime errors) for seL4 in 2009. I must be missing something.

Hi Gernot,
when analyzing the statement carefully, you'll find that it's indeed true. The seL4 source was *open-sourced* in July 2014 whereas the Muen source was released in August 2013.
But of cause you're right, we're not talking about the same properties here.
Cheers, Alex

… and even the above is at best of historical relevance.

Hi Jakub,
I really like the idea and implementation of this website. Having a place that provides an overview of the Microkernel movement as a whole may help to lower the barriers for outstanding people to get in touch with it. Maybe it also helps to keep events like the FOSDEM devroom going.
Cheers, Martin

Greetings
this is a good initiative, I like it.
Also, it seems to me, the content of the site can be enhanced by getting-started matherials of relevant projects, or (I prefer), MOOC project about microkernels with basics, history, architectures and examples based on different projects. Also, the final (graduate) practice of this project could be participation in GSOC or just resolving important issues in bug trackers. In my opinion, such course should be sufficient to turn any systems-friendly developer (student) to microkernel practitioner/developer/enthusiast capable to solve engineering issues of open source projects.
Several years ago we recorded some lectures bout the L4Re and Genode (Thanks Bjoerd, Norman, Udo):
https://www.youtube.com/channel/UCwBjjt60Mmp9X3N71mba3GQ
And of course there are many addition materials in any other projects, so, I do not think that it will be complicated to make joint course.
Finaly, about the diffusion of microkernels, I think it is important to see how all (and other) projects can be used to solv actual issues, thus, examples of application could also enchance the content (and impact) of the site.

Yes, the site can be definitely enhanced to contain more useful stuff such as tutorials, papers, blog entries and microkernel news. It could also serve as a basis for a prospective microkernel umbrella organization for the various summer of code programs and also the Microkernel devroom at FOSDEM in order to maximize chances of being accepted.
Focusing on the web site's content for now, I've already merged PR's of several people and am willing to continue within, including the creation of a menu and subpages for the above content as soon as it appears.

I do not know anything about the XstratuM
I just found it, but it seems that unlike Muen, it is under GPL version 2, not version 3, which means that it can be used for aggregate works that do not link to it without putting the rest of the parts under GPL. Just like the ordinary Linux kernel can be used for running proprietary software without affecting the license of the proprietary software.
The way I understand, the GPL v3 is infectious even, when linking is not done.
The XstratuM seems to be some European Space Agency project. I haven't studied the source, but at first glance it seems to be written in C, not Ada, which means that the de facto proprietary (GPL v3) AdaCore Ada implementation, the only thoroughly maintained Ada implementation (id est from commercial development point of view Ada is de facto proprietary programming language) a truly open, non-proprietary language can be used. Add to that the fact that formal verification tools for C and C++ tend to become more available,

the parties, who are not as loaded (with money) as the military-industrial complex is, might also have a chance.
Thank You for reading my letter. :-)

The license of the Muen kernel and the Muen toolchain is indeed GPLv3 but this does *not* cover components or subjects running on top of the Muen Separation Kernel. A note clarifying the intent is part of the projects COPYING file, see [1]. It is similar in spirit to the note in the Linux COPYING file [2] but we made it very explicit in an attempt to avoid any confusion.
Thus it is perfectly possible (and legal) to develop closed-source software that runs as a component/subject on top of the Muen kernel. We are also careful when choosing licenses for libraries that may be re-used by other parties, e.g. the shared memory channel library 'libmuchannel' is licensed under BSD [3].
We chose the GPLv3 for the Muen project so the community can benefit from development of the kernel and the toolchain.

The Ada compiler GNAT is and has been part of GCC, which is distributed by the Free Software Foundation, for quite some time [4]. To quote [5]:
The compiler is licensed under the terms of the GNU GPL 3+ with GCC Runtime Library Exception.
So, I fail to see how you arrive at the conclusion that Ada is a "de facto proprietary programming language".
the parties, who are not as loaded (with money) as the military-industrial complex is, might also have a chance.
The home of the Muen Project is the University of Applied Sciences HSR [6] in Rapperswil, Switzerland which is clearly not part of any military-industrial complex ;)
Thank You for reading my letter. :-)
Frankly, I was a bit surprised by your email, as we have discussed the Muen license in a private email conversation several months ago where you indicated that I was able to clarify the situation to your satisfaction. If you have further questions about this topic feel free to pick up our earlier conversation or ask questions on the Muen project mailing list [7].
Cheers, Adrian
