Forrestal Village: Forrestal Village is a 720000 sqft , 52 acre mixed-use retail and office complex in Plainsboro Township, Middlesex County, New Jersey, along Route 1.  Despite being in Plainsboro it has a Princeton address.  It is just north of Princeton University's Forrestal campus and is named for James Forrestal.  The center is anchored by Can Do Fitness (an upscale chain of fitness centers in the northeast) and a Westin hotel.  In recent years, it has suffered a sharp decline, turning into a dead mall.

ROMP: The ROMP or Research OPD Micro Processor was a 10 MHz RISC microprocessor designed by IBM in the early 1980s.  It is also known in some circles as 032.  "OPD" stands for "Office Products Division", the division of IBM which originated the processor.  The ROMP was manufactured on a 2 µm process with 45,000 transistors, saw first in silicon in 1981, and was originally developed to be used in office equipment and small computers.  It was intended as a follow-on to a mid-1970s processor called the "OPD Mini Processor", which was used in text editing systems such as the IBM Office System/6.  ROMP originally was shipped in the IBM RT/PC line, announced in 1986, and was later used in an IBM laser printer.  For a time the IBM RT/PC was planned to be a personal computer, with ROMP replacing the Intel 8088.  However, the software was targeted more towards engineering workstations.

Siège social: Siège social (French, usually translated Head Office) is a concept in international law for determining the nationality of companies.
