    There is an entire paper looking at the history, meaning and cultural significance of the foo, bar, baz words: https://link.springer.com/article/10.1007/s13347-019-00387-2

    A lot of programming languages uses "Foo bar" during introduction without actually explaining why "Foo" and why "bar". Before the age of Google and Internet it was perhaps one of the most common question from speakers of non-English language.

      This was one of the biggest hurdles I had to overcome when I was a wee lad combing through "Professional PHP Programming." All of the examples it gave were foo/bar, and I couldn't make the intellectual leap to understand what the real world use cases would be.

      It wasn't until I tried building something (mad libs) that things "clicked"

    This location in Switzerland reminded me of some placeholder Python code.

      If you opened a bar there, it'd be the Foo Bar. Full circle.

        Actually the river that goes next to it is called the Foobach (which would be pronounced close to foobar).

        I found that hilarious as I was hiking through that pass last year (beautiful area).

        Hire a barman named Baz

    Being largely self taught, I ended reinventing a lot of lingo myself. My placeholder words are generally “blah”, “yo”, and “fart” unless other people are reading the code.

    I never claimed I was terribly mature.

      I've used Blarg and Honk ever since Red vs Blue carved them into my mind

    funny how in italian the "Metasyntactic variable"[1] are "pippo", "pluto" and "paperino"

    I stole this handle from GLS many many years ago and I use it pretty much everywhere. I guess I just love the idea of metasyntactic variables, and using that phrase whenever anyone asks me about my handle!

    > First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud)

    I've seen foo, bar, baz, qu+x, plugh and xyxxy actually in use, not the others.

    I've not used "qux" or followed the convention of adding more u's. From me it's been just foo, bar, baz, quux and then some Monty Python inspired ones: spam, ni, ecky, ptong.

    Although eventually I learned enough about how to name things that I don't feel the temptation any more. I'll gladly pay that bit of joylessness to understand myself months later.

      IETF have a habit of posting "fun" RFCs on the 1st April each year. Some of them are more famous for being completely daft ("avian carriers" and climbing into trees to watch 0s and 1s painted on the top of tanks being the two stand-out ones), but it doesn't mean that everything they do on that date is to be disregarded as nonsense.

    I don’t understand how this article is not at the top of all times

  • zabzonk 6 hours ago ago

    naming is hard.

    my advice to junior programmers after i see them agonising over a name - "just call it x or foo for now, you are going to change it later anyway"

    f*kt up beyond all recognition. semper fidelis

    i first heard "foo bar" from eric allman at berkeley office of britton-lee, mid 1980s. i vaguely recall eric wrote a column about history of "foo bar".

    Now, tell us about "ZQX3".

    • stackghost 24 minutes ago ago

      This is the first time in my life encountering "ZQX3" in some context that suggests it has broad meaning.

      What does ZQX3 have to do with TFA?

  • taybin 8 hours ago ago

    No mention of “baz”

    • hk__2 3 hours ago ago

      It’s literally in the first sentence of the first definition:

      > bar /bar/ n. [JARGON] The second metasyntactic variable, after foo and before baz.

    • stephenlf 7 hours ago ago

      Part 2, 3rd definition of “foo”mentions baz
