in the virtual environment called OpenSimulator that we use and program, setup and maintain, you are being introduced to the world behind the places like InWorldz™ and SL® aka Second Life®
Those “places” are “wall gardens” (aka Closed platform) as they are known in the Free Libre, GNU, Open Source communities.
from Wikipedia A closed platform, walled garden or closed ecosystem[1][2] is a software system where the carrier or service provider has control over applications, content, and media, and restricts convenient access to non-approved applications or content. This is in contrast to an open platform, where consumers generally have unrestricted access to applications, content, and much more.
I am leaving you bread crumbs as you follow me through the process of getting the OpenSimulator up and running on a computer right here next to me 🙂
