Well, it is in early stage and development is almost inactive.
I have a soft spot for Frosted OS. Ok, it’s not an OS for PCs or even SBCs, it’s a POSIX compliant system for microcontrollers with MPUs, but a very cool project (Doom on STM32 anyone?) https://gitlab.com/insane-adding-machines/frosted
I also frequently check how Fuzix, Alan Cox’s unix for retro and low powered machines, is getting on http://www.fuzix.org/
There is also 4.4 BSD unix for pic32mz MCUs https://github.com/sergev/LiteBSD and 2.11 BSD for other pic32s http://retrobsd.org/wiki/doku.php/start
I honestly dont see it going anywhere
I’ve always enjoyed running and compiling alernative operating systems. This is of course why I’m here 
There’s some great info at https://wiki.osdev.org/Projects as well.
I miss SkyOS. I put so much time into bug reporting, hunting, playing, etc. with it. I could never understand why Robert Z. never would fix the main problem it had (ever increasing memory usage until it crashed). I had hoped when he lost interest that he would opensource it, but no 
I can’t base this feeling on anything concrete, but I have always felt when one of these hobbyist OSes does go under and the developer has no plan on ever doing anything else with it in the future… It makes me wonder if the ones that don’t open source everything actually using some open source code, but never admitted it. and they can’t release everything now because then people would be able to see that they were ripping off FOSS code.
Again there’s no way that I can prove that, but that’s kind of the feeling I’ve had about it for quite a while.
Some people are just not into the open source thing. SkyOS was Robert’s own work and it’s totally understandable that he doesn’t want anyone else to continue the project. Imagine if it was someone writing a series of books (say Harry Potter or something). The author has a right to decide that the book series is done. That does not put on them a moral obligation to release it under an open license and allow someone else to continue writing stories or “improving” the existing books?
I think it is well known thqt SkyOS took inspiration and probably some code from our BFS implementation (and our license allows for it, so it’s not a problem).
Better put your bets on Haiku that is a group project from the start and is set up so that people can come and go (and come back) as they want without putting the project at risk.
And that’s why this project and community has been going for almost 10 years at this point. 
More like 20, actually!
I was clearly still half asleep when I made that post. Hadn’t had my morning cup of tea to fully wake up. Haha
People who like Haiku would have really liked Syllable if it had continued. Both are C++ down to the core, and have similar smallish codebases. It’s too bad it’s no longer around. What’s interesting is that the website is still hanging in the Cloudfront system three years later, and nobody’s been there to clean up and remove the links. It’s as if the person who controlled the domain dropped off the face of the earth. Hope nothing bad happened to the guy.
Syllable was enough like BeOS to not really not all that interesting if you have Haiku. The file system, the API and the ethos was all very similar. It’s one of those situations where once the main developers lost interest, those that remained didn’t have the skills to continue. I think Kaj de Vos hung around a lot longer than Vanders, but it died for me when they started trying to add the Rebol stuff. I remember Vanders be adamant that config files in Rebol were a lot better and faster than XML… even though XML was the norm by that time for a lot of configuration. If you look at the github repo, it was all Kaj and all about rebol - very little else happened for years.
It appears somebody has updated the website and consolidated information about SyllableOS. Looks like the system itself hasn’t been updated since the last time I used it.
This is interesting. It looks like the Syllable OS is being brought out of dormancy by people behind the meta programming language. (Too generic a name, really - plus Meta is the company behind Facebook.) And that language is said to be a successor to the REBOL language. REBOL was easy to learn, so meta might not be much more difficult. That could mean more contributers and a thriving project. So a reborn OS could be on the horizon. Let’s hope it actually gets somewhere, and doesn’t get hung up on insurmountable problems…
This is not really what happened when REBOL was adopted by Syllable in addition to C++.
So far it seems it was just a refresh of the website, and the roadmap outlined there does not actually have any plans for the development of the OS itself, which is a bit strange for an OS project. I guess we should wait a bit and see how things unfolds from there. It would certainly be nice to see some development on Syllable again, but they do have some catch-up to do for all these years spent sleeping!
By looking at the Syllable Forum part I see that it is Kaj de Vos that has revived the project. That explains why all the focus is on the Meta programming language and not the Syllable OS itself. Learning from history I expect nothing to happen to Syllable OS, unfortunately.
REBOL essentially killed SyllableOS.
haiku is more useful than reactos.
there are five kinds of application with reactos 64.
but, you can see how much with haiku 64.
and, syllable is end，isn’t it?
Syllable is a different operating system from ReactOS. I don’t know how you got ReactOS out of Syllable. It is a different subject altogether.
