A new and improved Yahoo! Local Maps has been recently made available. It offers maps with significantly more interactivity for broadband users. It is written using AJAX, leveraging Rich Internet Application techniques. Some features:

Live traffic, address book, and send to phone features are also available.

Developers can embed Yahoo! Maps into their own web pages (to create a mashup) through the Yahoo! Maps Developer APIs. Many exciting new web sites have come about recently by displaying content from other sources on top of maps provided by the various mapping portals (the Google Maps API getting the most publicity). The Yahoo! Maps APIs come in three basic flavors:

Yahoo! offers a number of low-level APIs to support maps, for geocoding, getting a map image, searching for a local business, or retrieving traffic information. Some other Yahoo! services, such as Flickr and Upcoming.org, have their content available through web services, with interesting potential for mashups.

3-2-1 Contact is an American science educational television show that aired on PBS from 1980 to 1988, and an adjoining children's magazine. The show, a production of the Children's Television Workshop, teaches scientific principles and their applications. Dr. Edward G. Atkins, who was responsible for much of the scientific content of the show, felt that the TV program wouldn't replace a classroom but would open the viewers to ask questions about the scientific purpose of things.

3-2-1 Contact was the brainchild of Samuel Y. Gibbon, Jr., who had been the executive producer of The Electric Company for CTW from 1971 to 1977. (Gibbon actually left CTW before Contact's production began, though he was still credited as "Senior Consultant.")

The first season of 65 programs began airing January 14, 1980 on select PBS member stations; it featured a cast of three college students who discussed science in an on-campus room known as the Workshop. The first season came to an end on April 11, 1980, but funds for more episodes were not sufficient until 1982.
