Installing PHP on Windows: if PHP pages work but phpinfo is blank?
When installing PHP on IIS, I ran into this: in general, php files worked, but phpinfo.php files were not. They were blank when browsed.

PROBLEM: cannot load mcrypt extension. please check your php configuration
This could be due to the extension being missing or that it is not listed correctly in php.ini file. Listed below are the instructions from around the web that I followed to get this working:

IIS error: “The network location cannot be reached..”
If you have change the IP address that an IIS website is pointing to, then find that when you try to restart IIS services you get the error:
The network location cannot be reached.

Supporting Informal Learning
Informal learning is particularly useful where learners are not novices in a subject area and have some background, but are trying to add skills or need additional support for the details of unfamiliar tasks. Training people to find the information they need when they need it may work as well as training them to remember all the information they need, especially if they will not be putting the new skills to use frequently enough to keep it all memorized.
Javascript testing for NaN: why doesn’t !=”NaN” work?
A couple of weeks ago, I was working on a custom HTML wrapper for Captivate quizzes that would behave one way if a score were already stored for that quiz, and another if the score were non-existent or zero.
So, how best to test for the existence of a score? Usually I test for the existence of a value with

Mandelbulb 3D parameter experiments: Set 3 of 3
This is the third set of variations on one Mandelbulb 3D image.
The full set of variations is displayed below. All of these use Amazing Box, [something], Folding Int Pow, and ABoxVaryScale4d formulas with identical parameters, except for the second position which is filled in by whichever formula I was testing at the moment. The results of these experiments are yours to use and improve on. I usually tried one or two variations for each formula. There are plenty of interesting bits to explore throughout these images, far too many for me to ever do justice to all the possibilities. They also may give you an idea of what the different transformations can do.
