Thanks for the help. It makes my coursera ml-class notes easier to read.

One issue I had when I tried exporting to HTML with the dvnpng option the following equation:

\[
J(\theta) = - \frac{1}{m} \left[\sum_{i=1} ^m y^{(i)} \log h_\theta(x^{(i)})+(1-y^{(i)})\log(1-h_\theta(x^{(i)}))\right]
          + \frac{\lambda}{2m}\sum_{j=1} ^n \theta_j ^2
\]

in the png output I got the following trailing text:ORG-LIST-END-MARKER . Is this a known bug?

Regards,
Dov

org-preview-latex-fragment is really great but what is even better is that
it also works outside org-mode! This makes my life a lot easier.

I set "C-c P" as a global key-binding for org-preview-latex-fragment and
"C-c p" to org-ctrl-c-ctrl-c. Then I can preview equations all equations in
ANY buffer with "C-u C-u C-c P". It's great to write equations in comments
of some programming buffer (no matter which programming language) and being
able to render the equations right there.
