Good places to learn about open source software development

http://makethemove.net/

http://www.wlug.org/ 

The Worcester Linux Users' Group (WLUG) was setup to provide a forum for local users of Linux, a freeware clone of the Unix operating system.

While Linux is, in many cases, equal or superior to commercial Unix and other operating systems, it has no centralized technical support structure. This is actually a positive thing as there are many, many individuals on the Internet willing to help. Many times solutions can be found without much effort by contacting various online Linux sources and newsgroups. There are many Internet resources catering toward Linux users and WLUG was formed to assist Linux users in the Central Massachusetts area by creating a local member support system. WLUG members come from a variety of backgrounds and their Linux experience varies from the advanced to the novice. This mixture creates an enjoyable environment that enhances everyone's enjoyment of using Linux.

I will update this place frequently as and when i come across good links and sources!!!!
