Scriptics is the former name of the company that, during summer of 2000, became known as Ajuba Solutions.
http://www.scriptics.com/ was the commercial entrance point to Scriptics web site, but with the company rename, the website was also known as http://www.ajubasolutions.com/ .
http://dev.scriptics.com/ was the Tcl Developer's Xchange web entrance, where developers will find resource catalogs, web forums, download pages for various versions of Tcl and Tk, etc.
Note that as of November, 2000, Interwoven bought Ajuba Solutions and hosted, briefly, the web resources. This is now moving to ActiveState at http://tcl.activestate.com/ , with a safer longterm PURL to use of http://www.purl.org/net/tclhome .
