Mathjax CDN to shutdown April 30th 2017

Mathjax CDN to shutdown April 30th 2017

[Adam Aviv]

[-- Attachment #1.1: Type: text/plain, Size: 1065 bytes --]

Hi all,

I saw this blogpost recently about cdn.mathjax.org will be shutdown on
April 30th 2017.

https://www.mathjax.org/cdn-shutting-down/

There's a replacement to use cloudflair hosting instead

https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?...

Is there a plan to move the default org-mode mathjax header link over to
this by 30 April? It's a one line change in ox-htm.el for mathjax options.
I've attached that patch for convenience.  However, after a bit of
grepping, there should be some changes to the documentation which refers to
using the mathjax CDN and stuff.

On another note, the default option of using orgmode.org's hosting of
mathjax.sh should be updated to support HTTPS because most browsers block
scripts loaded under http if the page is loaded under https. Or, that
default should also change to the cloudflare cdn if it fits within the
terms of service. Perhaps that should be a discussion for another thread,
though.

I would personally try to avoid CloudFlare, because it currently forces
the site visitor to run non-(free/libre) software (automatically through
JavaScript).

And even if it's prooven to be free/libre, it currently doesn't tell
this to the user/visitor in a clear way (next to the place where the
script is, with a license, and address of complete corresponding source
in case it's currently obfuscated/minified).

AFAIU, it is only a default option. You can use something else.

Would you want to suggest a better option as the default value?

Would you want to provide a patch for that?

Have you signed FSF papers? Otherwise, you need to include "TINYCHANGE"
at the end of your commit message before I can apply it.

I've included both changes, to doc and the the html export in the attached
patch, now with properly commit message including the TINYCHANGE.

I would like to also figure out why (still can't track it down right now)
if you don't do the settings via (org-html-mathjax-options) you get
orgmode.org's hosting of mathjax.js via HTTP. It would seem wiser to either
host this under HTTPS so that the loading of mixed-content is not blocked
when using HTTPS or change that to also using the cdn.
