Good stuff hope to see more videos soon. Also, really good domain name!
That depends of course on your cultural and language background. In Germany, "NS" in a standard abbrevation for "Nationalsozialismus", the ideology of the Hitler regime from which the abbreviation "Nazi" derives. For instance, the time between '33 and '45 is typically called "NS-Zeit".
I don't think there's any danger, though, that anyone will confuse this website's content with anything related to that meaning ;-)
Of course "NS" is a play on Apple's Foundation classes that use the NextStep prefix for pseudo-namespaces.
It's unfortunate that it has connotations from our sordid past.
