Some of these tutorials and information guides have been written by Dewtronics, however, most of these have been extracted from various sources, as per this site's policy.  When possible, links are provided back to the original site, but they have been copied here since I'm sick and tired of hitting dead-end links when hunting for information on the web.  Links included here are the original links where the information was obtained, and there has been no effort in keeping these links up-to-date.  If you are an original author of one of these tutorials and don't like seeing your work published here, I seriously suggest you read this site's policy.

These tutorials have been compiled here because they contain valuable information on things pertaining to my subjects of interest, and I think many people with similar interests will find them helpful.  So enjoy this collection -- hopefully saving you time from having to compile from various sources on the web.
