Source and history of foobar

Source and history of foobar

 

Foobar isProgramPeople often see it, and its degree of fame is not inferior to Hello world. In general, our common usage includes the separation of Foo, bar, and the combination of foobar. This word can be used to represent everything in the computer field that needs to be named, variables, functions, and file names. In short, it can represent everything.

What is the meaning and source of the word? It seems that it is hard to say clearly. It does not mean that no one knows it, but that it is one person.

Rfc3092 specifically talked about this issue. Some people think that there is foobar first, and some say that there is foo first. The specific explanation is from the swearing words of the army during World War II (fouled up beyond all repair ), to the term of electronics (inverted Foo signal), the legend of Foo also comes from the military's nickname for unidentified objects (UFOS), some say it is a dog's name, and some say it comes from pop songs and cartoons, there are also many abbreviations (such as FTP operation over big address records.

I personally think it is easy to accept the following statement:

In the S and S, the digital handbook was introduced. In the early years, hacker (mostly software-oriented) generally used fubar, while computer engineers (mostly hardware-oriented) used foobar. Later, foobar gradually replaced the fubar usage and became more and more widely used.
