Nonlinear Input for (La)TeX IME

Published on June 25, 2014.

Since (La)TeX is a programming language (yes, it is a Turing-complete language) many of the math symbols are available as commands/functions and to help user type a text is need that the IME change the cursor position based on user inputs.

Math Fonts at Firefox OS

Published on June 17, 2014.

When dealing with math you need to have at least one font that has all the symbols needed with support to scale it. With at least one font properly installed, when visit https://www.mozilla.org/en-US/styleguide/products/firefox-os/typeface/ you will see something like:

Otherwise, you will see something like:
