digitalmars.D.learn - License of RosettaCode examples (for bearophile:-)

Can I ask you to clarify your licensing intentions for these examples?  By 
default all on RosettaCode is GNU Free Documentation License, which does not 
really play in a friendly way with ... just about any actual software license.

I imagine that all these examples were posted with the intention that they be 
used by others, but the default RosettaCode situation makes that impossible 
without direct permission.  So ... I'm asking. :-)

Thanks & best wishes,

An example of what the situation is using GNU FDL - last time I 
checked material under the GNU FDL could not be put into GPL code 
and GPL code could not be put into a GNU FDL manual.  So watch 
out! :-)

Indeed.  An unfortunate situation, no?

I am just following the common licensing you see in that site:
http://www.gnu.org/licenses/fdl-1.2.html

Recently the author of most of the PicoLisp entries has collected 
them in a commercial book, this has caused some troubles.

If you want info about Rosettacode licensing I suggest you go in 
the rosettacode IRC channel and talk with Mike Mol about it.

Would you be prepared to license your own examples under Boost?  I don't know 
what your intentions were for others' use of your code, but as it stands the
FDL 
license makes them impossible to re-use.

I am writing code for Rosettacode since years, I have written, 
rewritten, I have modified code written by others, and so on. I 
have also written many entries before having an account in that 
site, so there's no proof the author is me. I have also written 
many entries in Python, several in Haskell and C, some in C++, 
etc. While there are several entries that are written only by me, 
finding them is not easy. I didn't care about the owners of the 
code there. So I own nothing there. For re-use ask to Mike Mol.

I have a specific interest in your circular queue implementation:
http://rosettacode.org/wiki/Queue/Usage#Faster_Version

I used this (or rather, I adapted it) in a private project which is not being 
distributed, so hence there were no licensing issues.  I can't remember how I 
found it but I think it was when you posted it to the digitalmars.D mailing 
list: http://forum.dlang.org/post/grepielsmapflndpkmtk forum.dlang.org

... and at the time I think I just assumed that since you were pointing people 
to it and were the author, you'd licensed it permissively.

However, more recently I rather stupidly copied my adapted version into a
public 
project of mine, and I suddenly realized the licensing situation.

In the worst case scenario, I'll strip it out of the code, but I was hoping
that 
you might be willing to license this specific code under Boost or something
else 
GPL-compatible.

If you restrict your desires to just one D program, instead of
the about one thousand of Rosettacode the situation becomes
_much_ simpler :-)

I wrote that D code myself because Phobos still lacks a queue,
but the original idea of growable circular queues is decades old.
For Phobos I suggest a different and more complex implementation
(dynamic array of pointers to freelist-linked fixed sized chunks).

I have put that code only on Rosettacode, and in an archive in my
site. I am willing to release it to public domain if you want :-)
But what do you want me exactly to do? :-)

Very true. :-)  I'm sorry for not being sufficiently specific straight away,
but 
I thought the general question might be of interest.

I did try and write you a personal email about the specific code earlier today, 
before even writing to the list, but your given email address doesn't work.  I 
take it that I need to make some manual tweaks to what appears in the Reply: 
field ... ?

I made use of it ... because Phobos still lacks a queue. :-P  And I'll surely 
use Phobos' queue in its place once that is implemented.

Well, I guess the best thing would be just to write here, "I license the code 
under the terms of the Boost license" or something similar (public domain is in 
some ways less good because not every jurisdiction recognizes it, but as far as 
I'm concerned it's fine too).  I'm just looking for something that I can 
reference to say the code is used under these terms.

If you could add such a notice to the copy on your own site and on RosettaCode 
it would be even better because that means that it's then clear to everyone
what 
the use terms of the code are (I think RosettaCode allows you to add more 
permissive licenses to your code submissions, no?).  But that's up to you.  An 
explicit permission here is all I'm really looking for.

Whatever you decide, thanks very much for being so understanding and 
accommodating.  I'm very embarrassed about this, it is very unlike me to
neglect 
code licensing in this way. :-(

Thanks & best wishes,

I license the D program "Queue/Usage" (Faster Version) of the 
RosettaCode site under the terms of the Boost license. It 
implements in D2 a simple Circlular Queue able to grow 
geometrically. The code is visible in this page:

http://rosettacode.org/wiki/Queue/Usage#Faster_Version

Nearly all Rosettacode site entries (and all D entries) lack a 
license notice. It's just bad noise added.
For questions ask to Mike in the #rosettacode IRC channel.

Ahh, I think I misunderstood some of the RosettaCode documentation which had 
something along the lines of "Unless the code comes with a different license 
attached ..."

According to their Copyright page, it's advised to place license notices on
your 
RosettaCode user page if you want to use something apart from the GNU FDL:

I've added a Ddoc comment to the Dgraph codebase to reflect the origins of the 
code and your kind license grant:
https://github.com/WebDrake/Dgraph/commit/315286b9717e3d078029d77d0972800cbbd7dc42

Let me know if there's anything about that you'd like tweaked.  I can also
offer 
a link to your homepage, for example :-)
