I keep waiting for some poster to do a J-K flip flop.

Here's an interesting shibboleth:  In some electronics design professional
circles they aren't ever called "flip-flops", and doing so marks one as an
outsider.

I guess the old joke lyric "I got a brand new TTL cookbook,
you got the brand new C" is looking pretty dated.

And when was it that the beach wear started to be called flip-flops?

We called rubber beach sandals "flip-flops" starting when they were
first sold in the U.S., in the late 1950s or early 1960s.

As I recall the same flip-flops (footwear) were also
called "thongs" which has picked up another meaning
recently...

Once upon a time when my ex-wife was still my girlfriend
she was puzzled when I referred to her jandals as bistables.
She was my MSc ex-student so I insisted she figure it out
for herself. I must say after less than a minute she did
but said it was lame.
Wonder what she'd've thought of referring to this as a "threek":

Yes, the vacuum kind. Solid-state ones came later.

The OED cites it to 1958 in the footwear sense, 1935 in the hardware
sense.
I am shocked, *shocked* I tell you, that the OED would more
than one definition for a word.

My experience with them began in the steam-powered era, when they were
"go-aheads".

I once had a lovely double relay coil version: two coils, a hinged
armature with some springs to make it bistable, and some relay contacts.
It would sit forever in either state, and consume no power except when
switching. I looked for it last time I went home and couldn't find it
anywhere.

What are they called nowadays?

In those circles: "flops". Here's a randomly selected example of this
nomenclature in everyday use, from the very newsgroup that we are
discussing this in, from five months ago:

I have a clock signal coming into my FPGA. It is a slow clock (10kHz)
that drives a state machine. I want to bring it into another
clock domain by using a 3 flops in a row like shift register. The
clock driving the sync flops is much faster (90MHz).

I am actually running a gate level simulation (Altera Cyclone 3).
ModelSim tells me I have timing violations on the first flop in the
synchronizer, which is to be expected. But the remaining flops
in the sync circuit will move this async signal into the new domain
and should eliminate metastablity and setup/hold violations.

The culpability of a female or oneself is a matter of opinion, however.

I would've said that the process that a flip-flop undergoes is a flip.

And thus you, too, are marked as an outsider. (-:

AFAIK, flip-flops were named in the mid-60s... But I'm sure someone
older will remember that as even earlier!
