The Skrollr library has a great example of "pausing" scrolling to perform animations. In reality, scrolling does not pause, it only appears to because the background is fixed in place. I followed an excellent tutorial to create the Vectorworks 2015 Launch Microsite, but ran into some trouble when adding interactivity to fixed element animations.
I built and continue to support a Drupal Commerce site which has really complex discounts, but implementing even simple discounts can be tricky. I have found that the way that Drupal Commerce handles pricing is counter intuitive. That does not mean that it if wrong or needs to change, it just takes some getting used to. Unfortualtly, documentation is lacking. There are some good examples, but they are for very simple discounts.
I've been through it a couple of times now. You've got an application that is up and running, but now it needs to support Chinese. When you input Chinese (or Japanese or any language that uses a non Latin alphabet) you get weird characters in your database and on your web page. They're not Latin, they're not Chinese, what are they? They are an indication that you have a character encoding issue. Your application does not know how to encode those Chinese characters. It might be expecting all characters to be 8 bits and those Chinese characters are more.
I have been looking at some web frameworks to help accelerate my development and most of them use a technique called Object Relational Mapping (ORM) to map your data object models to a database. The problem is I find the implementation to create confusing code. I work in a PHP house, so I first looked at some of the big players: CodeIgniter, Yii, Symphony, CakePHP and Kohana. The more I worked with them and read about them, the more I realized that they were getting a lot of their ideas from Ruby on Rails. So I decided to check that out too.
I won't keep you writing on the results. Techsmith Camtasia is the winner... for me anyway.
I researched both these technologies a few years ago for marketing software and doing training and as an Adobe fanboy, I went with Captivate. I selected Adobe Captivate not just on the Adobe name, however. I also thought the underlying technology was superior.
Techsmith Camtasia is video based where Adobe Captivate is flash animation based.
