`foo`, `bar` and More

Though we always use foo or bar as placeholder for naming, do you know what's the next? Here (maybe) is a full list:

foo, bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud.

There are all metasyntactic variables (could be referenced from The Hacker's Dictionary).

• Foobar

Another widely used placeholder is the "Alice" and "Bob". And left succeed people have more choices, some common names are

• Alice and Bob
• Carol, Carlos or Charlie
• Dan, Dave or David
• Eve
• Frank
• ...

Even more they have fairly well-established "personalities" (or functions):

• Craig -> A password cracker, often encountered in situations with stored passwords
• Grace -> A government representative
