Mac OS X Easter Egg
I've found an Easter Egg (if it deserves that term) in Mac OS X 10.3 "Panther". Mac OS X ships with a command line utility called
appleping which enables you to ping machines on an AppleTalk network (as opposed to standard TCP networks). AppleTalk is rapidly becoming a thing of the past, but Apple has kept this utility in Mac OS X.
If you open a Terminal window and type
appleping and then press enter you will receive a usage message from the program which is as follows:
or: appleping name:type@zone [data size] [npackets]
examples: appleping 'John Sculley:Macintosh SE@Pepsi'
or: appleping 6b16.54
As you can plainly see, the example given is the user John Scully, CEO of Apple 1985-1993, on a Macintosh SE, in the zone Pepsi.
The joke is obvious. Scully was the CEO of Pepsi before he was hired by Apple in 1983. Legend has it that Jobs convinced him to come over to Apple by asking "Do you want to sell sugared water for the rest of your life?".
UPDATE: I've just confirmed that this very same
appleping utility has at least been present since the release of the incomplete Mac OS X Server 1.0, circa 1999, but may date to earlier Apple UNIX efforts, say mkLinux or A/UX.
UPDATE: This has been removed in Mac OS X 10.4 "Tiger". The output is now:
Usage: appleping net.node [data size] [npackets] or: appleping name:type@zone [data size] [npackets] examples: appleping 'John Doe:Macintosh SE@EndZone' or: appleping 6b16.5
