Different meaning of "Source Code"

Rating: 8/10 (16 April 2011)

In conventional usage, "source code" is the programming language that is human readable, which is converted to "assembly language" or "object code," which runs the computer. Commercial software firms never release the source code, and sell the binary object code, often at a handsome profit, think Microsoft Windows, for example. There are also Free and Open Source programs, such as Linux, Fire Fox, Open Office, and others whose source code is universally and freely available to anyone.
I went to this movie, thinking I would recognize some reference in the storyline to "Source Code," as described above. I found none. The computer program central to the plot was probably a top secret, and heavily guarded available to no one.
Otherwise, it was an exciting, gripping movie, well acted and directed, with a satisfying conclusion.
