You seem to be the only person, doing the latest work.</p>
<p>What is my angle? Would like to see MathML working, just as HTML 3.2 does. (Seems to be getting there.) Mathematical typesetting in browsers, matching of LaTeX format.</p>

<p>Mentioned you on Twitter. Just FYI.</p>Improvements to Mathematics on Wikipedia - Blupperurn:md5:ff86bea6f919c377876a5b5ea9753c202014-01-13T20:24:18+01:002014-01-13T21:24:18+01:00Blupper<p>"One issue for the MediaWiki developers is that this program is written in OCaml and no longer maintained"<br />
Is OCaml so horrible? How about reworking it in Haskell. ;D<br />
Jokes aside, I believe seeing a patch for it not that long ago, but it might have been just some small fix and the sooner everyone will leave the raster graphic formula world the better. Thanks for all your effort!</p>Gecko-based EPUB Readers and LaTeXML - fredwurn:md5:f2b4ce5ae2a71644c13938de323a8cfd2013-11-11T13:31:30+01:002013-11-11T14:31:30+01:00fredw<p>@michal.h21: thank you, that's great! I knew that some people used TeX4ht to convert to EPUB3 (XHTML+MathML) but I was not aware of a direct conversion tool. Configuration for the UniqueIdentifier or CoverImage looks a very good idea that is currently missing for LaTeXML.</p>Gecko-based EPUB Readers and LaTeXML - michal.h21urn:md5:ad2e7b00afe0a4876f310777066161832013-11-10T16:40:54+01:002013-11-14T19:06:54+01:00michal.h21<p>There is also another direct option for LaTeX to epub3 conversion - <a href="https://github.com/michal-h21/tex4ebook" title="https://github.com/michal-h21/tex4ebook." rel="nofollow">https://github.com/michal-h21/tex4e...</a> For some sample output, see <a href="http://homepages.ulb.ac.be/~gbarnich/preprints.html" title="http://homepages.ulb.ac.be/~gbarnich/preprints.html" rel="nofollow">http://homepages.ulb.ac.be/~gbarnic...</a> or <a href="https://github.com/michal-h21/epub3sample" title="https://github.com/michal-h21/epub3sample" rel="nofollow">https://github.com/michal-h21/epub3...</a></p>Gecko-based EPUB Readers and LaTeXML - Raniereurn:md5:e1601a022fbd30196ea77a405d4473ef2013-11-09T02:31:24+01:002013-11-09T03:31:24+01:00Raniere<p>@fredw: Thanks for the reply.

LaTeXML now makes creating an ebook easy but it lacks interactivity feature. At the moment one would need some basic knowledge of HTML and Javascript in order to write such a book. There are probably several options like creating general Javascript libraries to make programming easier (such as <a href="http://sdiehl.github.io/jquery-mathml/" rel="nofollow">jquery-mathml</a>), or defining some "widgets" as Paul mentioned or inventing LaTeX macros and packages that could help (see <a href="http://lists.jacobs-university.de/pipermail/project-latexml/2013-October/001537.html" rel="nofollow">my post on the LaTeXML mailing list</a>) or creating some kind of high level Web authoring tools for math similar to <a href="https://webmaker.org" rel="nofollow">WebMaker</a>.</p>Gecko-based EPUB Readers and LaTeXML - Raniereurn:md5:70fd7ec267f681f8232e2fe7f9f71aaa2013-11-08T12:38:36+01:002013-11-08T13:38:36+01:00Raniere<p>@fredw About education applications, did you post the link to the epub used in your video? And do you know a tool that any math teacher (not a programmer) can use to create a ebook like the one in the video?</p>Gecko-based EPUB Readers and LaTeXML - bastiaanurn:md5:f485c8a54acf7ccd4f66816dc498995d2013-11-08T12:33:59+01:002013-11-08T13:33:59+01:00bastiaan<p>Raniere: sure, having the tools is good. I think changing the way science is done requires that the incentive model changes. As it is, the incentive model creates a number of very negative side effects, such as not publishing 'boring' results, rush-to-press, sloppy research and peer review, and even unscientific or dishonest reporting. So the good news is the model has to change anyway.</p>
<p>fredw: agreed.</p>Gecko-based EPUB Readers and LaTeXML - fredwurn:md5:d7af49806b3d9f6408ca59cc9a4619772013-11-08T09:19:35+01:002013-11-08T10:19:35+01:00fredw<p>@bastiaan: yes, I'm aware that most researchers do not want to do their work in public and as Raniere said that was my point when quoting the Mozilla Science Lab. However, publishing their papers is important and they progressively start to use the Web to reach a larger audience, even if that's as a "repository of pdf papers" like arxiv. Even if only the final work is published, it is important to have something that can be read by accessible tools, adapted to the screen size (reflowed, linebroken, zoom in/out) or recognizable by search engines (there are projects to search MathML formulas) ; otherwise they don't need the Web they themselves invented, but only the Internet. That said my blog post was not on research only, that was just a casual remark to mention Mozilla Science Lab. I'm considering more general applications from education to academia (thus my example of the interactive course on matrices). Ebooks are particularly interesting for textbooks from school to college or specialized books giving the state of the art of a research field. And more and more Websites like Arxiv or Wikipedia are migrating to MathML in order to display mathematical formulas. Having a format like EPUB that is just zipped Web pages is important to get something 100% compatible and avoid duplicate effort.</p>
