The MathJax project is looking for a Business Development Manager. You can read more about the position on our jobs page. A major focus of the job will be promoting and facilitating the use of MathJax in the exciting and rapidly-growing ebooks market.

Our first Business Development Manager, Hylke Koers, moved to a full-time position with Elsevier at the end of the summer. He began shortly after MathJax 1.0 was released, and helped the project broaden its base of sponsors, establish the CDN, foster integration with leading web platforms, and build adoption to the point where more than half a million pages access the CDN a week today.

The next MathJax Business Development manager will begin with an established, well-regarded project. We look forward to seeing what the next stage of MathJax’s evolution will look like under the guidance of another talented and ambitious person, eager to make a difference in the sphere of math and science communication.

Over the upcoming weekend of September 11-12, we will be making a modification to the MathJax CDN. Web sites using the CDN won’t be affected, and the CDN service will remain continuously available. The change is aimed at resolving a problem affecting some users of Internet Explorer. Technical details are given below.

Change
Requests to the MathJax CDN that don’t contain an “Accept-Encoding: gzip, deflate” HTTP header will in future be served with uncompressed content.

Rationale
Up to now the MathJax CDN has delivered gzip compressed content for all non-image requests, even when the “Accept-Encoding: gzip, deflate” header was absent. This meant that browsers could still receive faster gzip’d responses even if an intermediate proxy (for instance) had stripped the header.

Unfortunately, all versions of Internet Explorer disable gzip handling completely when HTTP 1.1 is disabled. This can occur in several ways, including

1. when a user does not have administrator privileges, regardless of the
   advanced configuration option “Use HTTP 1.1″ setting, or
2. when the advanced configuration option “Use HTTP 1.1″ is disabled, or
3. when the advanced configuration option “Use HTTP 1.1 through proxy
   connections” is disabled and a HTTP request is made through a proxy.

The upcoming change will maximize the number of users who are able to
receive content from the MathJax CDN.

Implications

1. There is no need to change the way you use the MathJax CDN with your
   pages.
2. There may be a few users of Internet Explorer who previously could
   not view math in your pages, but now are able to.
3. There may be a few users who have a slightly slower experience due to
   not receiving gzip’d content from the MathJax CDN.

MathJax is experiencing a rapid growth in the domain of online learning resources. The MathJax CDN usage figures (see also this News post from June 2011) indicate that the MathJax user base is growing and diversifying, particularly in the domain of online learning resources. These range from online math encyclopedias to integrated course material, and from online math quizzes to test preparation services.

Motivated by this rapid uptake, we have looked deeper into how MathJax is being used by the e-learning community and released an article that describes this on mathjax.org. Please read “Mathematics E-learning Community Benefits from MathJax” to learn more about the landscape of mathematical e-learning websites, and to understand how MathJax is helping online educators to teach mathematics on the web.

The MathJax project is pleased to welcome IOP Publishing as a new MathJax Supporter.
