Put simply, a Dependency Injection Container alleviates the need for factories and the use of new in your code. Think of DiC as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts.
This module enables Symfony's Dependency Injection component for Drupal 7 modules.
This is a very simple module that takes the link text of each drupal menu item and adds it as a css class name to the menu's <li> element. Using these class names, each menu item can be styled separately with css. This is also very useful for css sprite techniques.
This module provides a geo-location block for your Drupal site, which displays to your visitors their:
IP address
Internet Service Provider's Name
Telephone Area Code
City
State
Zip/Postal Code
Country's flag
Country's Name/Code
Latitude
Longitude
DMA Code (kind of "optionally"... if enough people say that they care to have that feature then I'll commit it but otherwise I'll leave it as is for now)
