Gio retired from full time active service at Stanford 30 June 2001.
He will not take on new students or assistants, and not participate
actively in new research projects.
In 2014 he stopped teaching the Spring quarter Freshman seminar of `Business on the Internet',
CS73N.
He will be available to help with the dissemination of prior work.
Gio is actively
consulting now, mainly on issues related to IP valuation. Results of
this work were published in the Comm.of the
ACM, September 2006 issue and subsequuently.
This led to a book Valuing IntelLectual Capital.
Voy and Gio are still developing and maintaining the Historic Computer Displays at Stanford in the Gates Information Science building. The latest addition is original S-1 Supercomputer. S-1 Supercomputer.
Colleagues, then current and former students donated a bench in
San Francisco's Mountain Lake Park in appreciation.
It is located just north of the intersection of Lake or California street
and 12th Avenue, and has a view of the lake, the trees of the Presidio,
the drive to the Golden Gate bridge (CA Highway 1), and the adjoining playground
(SF

The Wiederhold genealogy now has its own web page Wiederhold.org. As of 2020 the pages cited in the next paragraph are now longer being maintained.
Using voluminous paper documents that Gio obtained from a now deceased genealogist in Germany, Alfred Wiederhold, Gio is transferring, cross-checking, and expanding the data into files that can be persused on-line. The current (Spring 2018) goal is to have all known Wiederholds born prior to 1800, as well as their spouses and children, on-line. The earliest Wiederhold entries are in 1140, where a Wedderhold was a judge in Warburg, on the Hessen-Westfalen border in Germany. Active lines will be followed to the year 2000, although privacy rules inhibit publication of people that might still be alive, unles they have given permission. All Wiederholds appear to be related!.
Gio also has collected his academic ancestry, which goes back to Galileo Daliei (1564-1642) and his adivsors. That measn ofcourse that all of Gio's descendant students inherite the same academic ancestors. Historical Stanford connections include David Starr Jordan and Lewis M. Terman.
.At the end of 2006 Gio finally got around to a planned retirement project, restoring
a 1953 Armstrong Siddeley Sapphire saloon he bought in 1960, but mangeled in late 1963, to roadworthiness

But if you just go to YouTube and enter

you should get it.)
I participated in an Armstrong Siddeley rally in July/August 2008 in the Australian Outback --when it is winter there-, driving other Sapphire cars and stopping in Sapphire, Queensland. Look at
