Solving technology problems, one at a time
If you get this error when trying to upgrade the operating system on an iPhone or iPad:

Things to try:

At the same time, there has been increasing demand from subject matter experts and educators for inexpensive, easy to learn tools like Captivate that leverage their Powerpoint skills but have plenty of flexibility and options for interactivity. So something had to be done to make Captivate useful again.
What I decided to do was to turn over all the SCORM communication for Captivate activities to our HTML template, which doesn’t have the communication issues of the Adobe products. Using the SCORM template as a wrapper does not add a lot of work to a project, in fact, it requires only one line of code to add a scored Captivate or Presenter quiz to a template-based learning module.
Any type of scored Captivate file will work – both question slides and interactive slides. The module can handle one or more Captivate quizzes, either by themselves, or in combination with other types of content and quizzes, such as Questionmark Perception or the template-based interaction quizlets.

Our LMS users sometimes have problems accessing SCORM learning activities. These days, when all other possible causes (java not installed, security settings, etc.) have been eliminated, the next most likely culprit is an expired certificate. The JAVA adaptor used by our LMS is very particular about security, and fails with various silent exceptions if the certificates aren’t in order.
If you have followed all the instructions that come with your new iPhone, only to be faced with a “Waiting for Activation” message that remains unchanged for hours, try powering the phone down completely. Press

Action application/x-hg-php53 /cgi-sys/php53 AddType application/x-hg-php53 .php
to an .htaccess file located in the public_html directory of your site. If Drupal is not at the root of your site, and you don’t want to change the entire site over, it works just as well to modify the .htaccess file in the Drupal directory.
An .htaccess file is just a text file named “.htacess” which can contain many different types of directives understood by the apache server.

The other day I received a PDF file that need to be converted back to Word or text format. But every attempt to save it from Acrobat Pro to Word resulted in the error shown above:
