 I am pondering offering engraving services with LilyPond. I wonder if
 there are people ready and willing to share information on the
 possibility to make modest money this way.

 I found one (slightly broken) thread in the archives:

 http://lists.gnu.org/archive/html/lilypond-user/2007-10/msg00482.html

 http://lists.gnu.org/archive/html/lilypond-user/2007-11/msg2.html

 which indicates that several people use LilyPond for professional
 projects, but they seem to be activities within a larger job, rather
 than pay specifically for engraving.

 I found one person offering Finale engraving ranging from 2 cents to 5
 cents per note:

 http://home.earthlink.net/~rscarbro/russell/music_prep.htmhttp://home.earthlink.net/%7Erscarbro/russell/music_prep.htm

 but I didn't understand precisely what he was charging for. His examples
 looked to me inferior to LilyPond results, but they were in low
 resolution pictures.

 I found a list of people offering mostly Finale engraving from $20 to
 $80 per hour:

 http://www.musicengravers.com/

 I have no idea how much they accomplish in one hour. I like the relative
 objectivity of a charge per note.

 So, if there is enough interest (i.e., at least 2 other people), I
 suggest that we develop a discussion within the LilyPond Wiki:

 http://wiki.lilynet.net/index.php/Main_Page

 If there's enough response, I'll join the Wiki, make sure that this is
 within it's scope, and provide a front page. So far, I have some
 examples to share, and a crude sed script for counting notes.

 Cheers,

 Mike O'Donnell

just fyi:

as far as i know, in the netherlands with finale, engravers get paid per
FRAME - this is a built-in function in the software.

 Yes, please.  If that extension shows only the LilyPond source code of
 snippets but the normal page view and the printable view show these
 snippets processed and converted to PNG, it surely means that LilyPond
 is not called to process these snippets from Extension:Collection.

 By the way, for a decent printing quality, the PDF generation should
 not be left to the user browser but should be done on the server side
 (using PDF snippets generated by LilyPond), like what
 openstreetmap.org does.  This regards standard printable view as well
 as the extension Collection.

 Best,
 John


thank you very much!
with the help of your analysis, i now filed a bug to this collection, hoping
it will be fixed in the near future.

hmm, as it turns out, pediapress refuses to fix this, the reasons given are:

 You can install and use this extension in your wiki, but it is currently
 not available in Wikipedia. Many people would love to use this extension
 in Wikipedia and other large-footprint wikis that they have no control
 over. However, in its current form, this is unfortunately impossible due
 to security concerns.

 This extension is using Lilypond's safe mode, which according to the
 documentation does not detect resource overuse. It is still possible to
 make the program hang indefinitely, for example by feeding cyclic data
 structures into the backend. Therefore, if using LilyPond on a publicly
 accessible webserver, the process should be limited in both CPU and memory
 usage. This extension is therefore not used in Wikipedia because it is
 considered a hazardous denial-of-service vector.

is this correct, that lilypond has this security issue as stated; and is
it possible  to make the program hang indefinitely?

thanks in advance and all the best,
oscar

 This is not a reason not to support LilyPond processing as a option that
 is switchable by a configuration file accessible only to the website
 administrator, which would be disabled by default.

 Adding to Kieren's example, think that LilyPond user interface is a
 programming language, so it is hard to avoid these problems, that's the
 workaround that consists of limiting CPU and memory usage is
 recommended.  Even with normal use of such an extension, you need much
 CPU power and free memory, which is surely not available on many servers
 running MediaWiki.

 Best,
 John


thank you kieren and john, things have become much more clear to me after
this thread so far.
i will ponder on how to perhaps make it run a bit more safely on my website,
and keep on using it, as lilypond is relatively userfriendly, very powerful,
and essential there :-)

fyi to the pediapress people i wrote, to conclude ticket #775 i mentioned
earlier:

still, in my humble opinion, not including lilypond in the pdf rendering
extension:collection is a missed chance for pediapress as well, since to me
it seems to concern its field of business, and a possible venture into a
whole new field: open source music printing. but i will not push the issue
further at this point (and leave this ticket closed). i think however
pediapress is missing out on an opportunity, but this is also a matter of
choices of priority, and we may vary in this of course.

i personally believe it would be more than worth the efforts to tackle this
all the best,
oscar

Lilypond as MediaWiki extension does not print in Extension:Collection

2010-01-27 Thread Oscar van Dillen
dear all,

on my website I found that Lilypond as MediaWiki extension does not print
music notation, just code, to the pdf in Extension:Collection
http://www.mediawiki.org/wiki/Extension:Collection
Lilypond does work fine when using printable version such as can be seen
here http://www.oscarvandillen.com/Triad?printable=yes

*is it my configuration? see
http://www.oscarvandillen.com/Special:Version(Lilypond is invisible
there but installed)
*is this a know issue? (i didn't find it anywhere yet)

should I rather tell the collection programmers at
http://www.mediawiki.org/wiki/Extension:Collection/Wishlist or is it
something that must be solved by the Lilypond programmers?

very best,
oscar
