Dark days for MathML support in browsers

By Christian Lawson-Perfect. Posted November 1, 2013

For a brief moment at the start of the year, Google’s Chrome browser could render mathematical notation written in MathML. Since then, things have got worse for mathematics on the web.

In February, the MathML rendering code was removed by Google, citing concerns about security and code quality. Now, a member of the Chromium team has announced that Google will not be supporting MathML in the foreseeable future:

MathML is not something that we want at this time. We believe the needs of MathML can be sufficiently met by libraries like MathJax and doesn’t need to be more directly supported by the platform. In areas where libraries like MathJax are not good enough, we’d love to hear feedback about what APIs we would need to expose so that MathJax, et al, can create an awesome MathML implementation.

Peter Krautzberger, manager of the MathJax project, is not happy.

GeoGebra now available for tablets

By Peter Rowlett. Posted September 15, 2013

You may be aware of GeoGebra. In a previous post, our very own CP described it as “a surprisingly capable piece of free dynamic maths software, used widely by teachers and geometry aficionados”. I am preparing lecture notes for the new academic year and have been making diagrams in GeoGebra (on Ubuntu, since you asked), both to print in my notes and animate in my lectures. I can insert $\LaTeX$ labels and export as code for PGF or PSTricks. Here’s one:



Now, following a successful Kickstarter (which we covered in a previous post), GeoGebra have released tablet versions of the software. So GeoGebra is now available on Windows, OS X and various flavours of Linux (.deb, .rpm, other), as a Chrome App, a Chrome Web Application and in a ‘Java Webstart‘ version (though be aware that the Java Webstart is being phased out), and now for Windows 8 or RT, Android and iPad tablets. Here is a screenshot of the iPad app:

Chrome no longer supports MathML

By Peter Rowlett. Posted February 7, 2013

Recently we reported that Chrome has added support for MathML, a good method for representing maths on the web. Now a comment on a discussion about enabling MathML in Chromium, the open source web browser project from which Google Chrome draws its source code, has announced that this feature will be turned off, for now. The comment, from user meh@chromium.org yesterday, says:

Note that MathML has had to be turned off because the code is not yet production ready.
We hope to turn it on in some future release. We plan to announce this in the Chrome 25 release notes.

Earlier today user isherman@chromium.org posted this clarification:

To summarize the current status of this bug: We’d like to enable MathML in Chrome, but the WebKit code still needs further improvements before we can ship it.
