This groups includes about 200 communication satellites ("comsats") scattered in synchronous orbits above the Earth's equator. ... 6 Earth radii (42,000 km or 26,000 miles), these satellite make one orbit per day, and therefore as the Earth turns, they always stay above the same ground station. ... Still another application is the 24-satellite network of the "Global Positioning System" (GPS), in circular orbits at distances of about 4.1 Earth radii (26,000 km or 16,000 miles). ...

XPA supports both inet and unix (local) socket communication. XPA uses sockets for communication between processes. It supports three methods of socket communication: inet, localhost, and unix. ... You can set up a different method by typing something like: setenv XPA_METHOD local # unix csh XPA_METHOD=local; export XPA_METHOD # unix sh, bash, windows/cygwin set XPA_METHOD=localhost # dos/windows The options for XPA_METHOD are: inet , unix (or local ), and localhost . ...

... And the Geminid meteors are now building towards maximum, on the night of 12/13 or 13/14 December, depending on who you believe! ... If you wait until the radiant is at its highest point, and for an hour or two after, you might see about 100 or more Geminids per hour from a very dark location. ... Not at the radiant, believe it or not! ... If it's cloudy those two nights, don't worry - you will still see some Geminids any night from tonight right into the weekend. ...
