Multithumb fix

I use a third party Joomla extension library, BK-Thumb, to manage pictures on some of my pages. A recentl Joomla updated caused a spurious Multithumb error to show up on several of my pages that do not even use Multithumb features. This has now been corrected.

Miscellaneous section

Reorganized the Miscellaneous writings section, created a new subcategory for my ramblings from the pre-blog era.

Equation formatting

Tonight, I updated this site so that all pages that contain mathematical equations now use MathJax instead of the older jsMath. MathJax works much better, it seems, than jsMath, especially in Internet Explorer. Hopefully, the equations are still correct after all this formatting and reformatting. Hopefully, they were correct in the first place.

Settlement Date Calendar

Imported the NASDAQ Settlement Date Calendar, a Web application I developed years ago, into the CMS site.
