Drupal 8.4.x New Features

• OOPS not Procedural Coding
  Drupal 8 is object oriented and Drupal 7 is primarily procedural. You need to work with Classes to implement your code rather than writing simple functions. OOPS programming is more flexible for module development.
• Namespace
  Drupal 8 uses namespace. Namespacing ensures that your class does not conflict with another class of the same name.

A few years ago I had the opportunity to develop a set of teaching tutorials for a security systems company. In doing so, I used Camtasia to develop a set of video's which helped the user install, and setup various systems related to the security application software they sold. It was a great way to disperse information in a format, which appealed to more then 90% of the customer base.

Since I get this question all the time let me just define why you should use a source repository for Development and File Backup Activities.

VDD is virtualized environment, so your base system will not be changed and remain clean after installation. You can create as many environments as you wish without any consequences.

The main goal of the project is to provide easy to use fully functional, highly customizable and extendable Linux based environment for Drupal development.
