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

Smokey Stover, the 1935 "Where there's foo, there's fire" guy, was a TV cartoon in the 1970s. https://en.wikipedia.org/wiki/Smokey_Stover#Animation Influenced by german furchtbar/foobar/fubar, MIT used fu() and bar() in the late '30s.

The paper goes deeper

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.

https://en.wikipedia.org/wiki/Foo_Pass

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

And have them serve a cocktail called the quux

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

[1] https://en.wikipedia.org/wiki/Metasyntactic_variable#Italian

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!

Turns out “foo/bar/baz” has lore. I assumed it was just tribal placeholder magic. Now I’m wondering what other dev fossils we still carry around - IDDQD (Doom god-mode) is a personal favorite. What’s yours?

In case anyone else has ever wondered:

IDDQD stands for Id Delta Quit Delta, a fraternity created by DOOM programmer Dave Taylor who released that if you drop out or quit a course you get a statistically-better final grade than you would by failing the course. Of course, you still end up not achieving a degree, hence when used in-game it shows "Degreelessness Mode" activated.

Excuse me, fossils?

It's only offensive if you're being carried around.

I think they're referring to the artifacts (like foo) rather than people.

Yes and still don't comprehend why to call certain things fossils if they are still used by virtually everybody

Petroleum is used by everyone right? And it's a literal fossil. I wouldn't call it a fossil because all terminology has lore, but the idea as I understand it is that it's an artifact that outlived the context it was originally relevant in.

> It has been plausibly suggested that "foobar" spread among early computer engineers partly because of FUBAR and partly because "foo bar" parses in electronics techspeak as an inverted foo signal.

Can anyone educate me what "inverted foo signal" means here, in connection to electronics?

I believe Ā is notation for "not A" and is read out loud as "A bar".

thanks! this makes sense

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

I always hated foo, bar, & baz. These vars are always pushed by uncreative individuals. I directly equate it with middle-management types that drive black BMWs and have the personality of milquetoast and golf. No thanks, I'll stick with zig, zag, and zip. If you don't like it too bad, write your own throwaway code.

April 1, 2001

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.

Something can be humorous without being nonsense, such as this RFC.

I'll have an apotropaic inscription to go, please.

> 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.

I've never seen qu+x, except in the title of that Gundam installment released last year, Gundam gquuuuuux. I found this speculation on myanimelist sufficient, but there's no real confirmation afaik. https://myanimelist.net/forum/?goto=post&topicid=2209708&id=...

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"

“It might be hard, but don’t let that stop you from making it worse” :)

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

Not to be confused with https://en.wikipedia.org/wiki/Shmoo , although I have used that as a metasyntactic variable before.

Echoes of ARPANET.

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".

I’m disappointed it’s not originating from the Mexican “Foos”.

Now, tell us about "ZQX3".

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?

No mention of “baz”

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

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

In the etymology section, I presume. And I can't find it either, if it is there.

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