hmm..
fork to me is when you clone repositorys and change stuff and loose ncompability with upstream?

Well, forks can have different variety. You can copy part of the code, while not some other part. At least partially it's a fork. May be Stskeeps can clarify the actual relation between Mer and MeeGo project code wise. And not all forks are supposed to lose compatibility as well. Fork just means a parallel development / cloned codebase for whatever reason.

I'd rather call it continuation of MeeGo since the original project is dead. In any case that's just semantics, the main point is that the code and the idea lives on with Mer.

Yes. So it's somewhat confusing to say that Jolla is based on Meego and Mer (like Wiki says now). I'd say like Stskeeps that it's based on Mer and continues MeeGo spirit.

Some examples of forks that I can think off the top of my head;

Nessus -> OpenVAS
The fork was because Nessus decided to become more commercial and / or stopped accepting code from the community. (I might be remembering that a little wrong)

Nagios -> Icinga. Nagios didn't want to change it's look, felt like they wanted to commercialize it and stopped accepting patches for bugs, so Icinga was created.

Redmine -> Chiliproject
Not entirely sure on this one, but it looks like a lot of Chiliprojects goals are to revamp the interface of Redmine. This particular case, I don't think they should have forked it, and instead just helped out with the main project.

MeeGo -> (current) Mer.
From what I understand of it, Mer was a project before MeeGo, right? A project to bring Maemo to other platforms, but then MeeGo came about and it seemed to fade away for a while, then MeeGo had Nokia leave the project, then Intel, and now Mer takes over where MeeGo left off.

Pretty sure I got all of that right. But if not. Meh

Well, Mer did exist before Meego being based on Maemo efforts, but it redefined itself after Meego later.

And an example of fork with maintaining compatibility is OpenSolaris -> illumos.

XFree86 -> X.org
OpenOffice -> LibreOffice
GCC -> EGCS (-> GCC)

Build a comercial phone with mer is really intressting and strange. How will that succeed?

Im waiting for announcment.

The only hope for Jolla is to be able to create something that, on some level, is interesting for Baidu in their OS.

I hope they have some cool things up it sleeves. The OS alone will not do it. Its all about Elops favorite word: ECOSYSTEM.

Im still waiting. Will be an awasome announcment.
