There are other metrics people look at. A critique about those kind of stories is the unemployment rate is designed to target a specific feature of the economy and using it as a proxy for "hard times" is a failure of intuition as much as a failure of the metric.
Does the same criticism apply to those who look at the unemployment rate and use it as a proxy for "good times" (as evidenced by the low unemployment rate)?
I hate this fucking critique. You compare U-3 to U-3 historically. If you want to include underemployed and discouraged workers, look at U-6*. It exists and it's tracked historically. The classic move is partisans comparing U-6 to U-3 to say things are bad because look. U-3 is popular for the same reason as the Dow, you can compare over many many decades.

* U-6 pre recession low was at 8.0%, recent low was 8.4%

My favorite part of the story is:
The women’s group, on which we were now relying, wasn’t really any more encouraging. One of them said “It looks and tastes like Kaolin & Morphine”, which was a popular medicine for diarrhea (it’s still around).

The Geneva drive is a mechanical way of translating continuous rotary motion into intermittent rotary motion. It's one of those things that seems kind of obvious once you look at it, but must have taken a leap of imagination to design for the first time.

Cool. And I agree. Obvious in retrospect, like many things. Would be difficult to originate the concept.

You don't see them much, they tend to wear out quickly.

ETA
From Wikipedia:
The figure shows the motions curves for an external four-slots Geneva drive, in arbitrary units. There is a discontinuity in the acceleration when the drive pin enters and leaves the slot. This generates an "infinite" peak of jerk (Dirac peak), and therefore vibrations.

Motion curves for one turn of the drive wheel, from top to bottom: angular position θ, angular velocity ω, angular acceleration α and angular jerk ja.

This shape not only has a name, the squircle, but there is a specific mathematical formula for it.

There is a mythological beast called the lampago, with the body of a leopard (or similar big cat) and the head of a man. It seems to have little existence outside of heraldry, as in the arms of the Radford family.

Caught part of a Johnny Carson re-run last night in which the topic of conversation was Carter's Chief of Staff Hamilton Jordan, which led me to discover that the republic survived the white house not having a chief of staff for the first couple of years of Carter's presidency. As well as prior to 1946. However did we manage.

Doubtful that the Trump administration would permit the country's survival without a chief of staff.

As Turkish is an agglutinative language, it's hard to say what the "longest word" in it is, since it is possible at least in theory to add affixes endlessly, but the longest word ever used in a Turkish text was Muvaffakiyetsizleştiricileştiriveremeyebileceklerimizdenmişsinizcesine, which means roughly "As though you happen to have been from among those whom we will not be able to easily make a maker of unsuccessful ones".

As a funny aside, the word is pretty artificial and tortured even for native Turkish speakers, who have a lot of trouble saying it.

I was having my blood pressure taken the other day, with the usual inflatable arm-cuff thing, and it occurred to me to ask the nurse, "How do you take someone's blood pressure if they have no arms?" The answer is: those cuffs can be put around the thigh, too.

And in case you're wondering the next obvious question, unfortunately the nurse did not know how you take the blood pressure of somebody with no arms or legs.

Really fat people are encouraged to ask for thigh cuffs to be used on their arms, for a more accurate reading.

I read that Eskimo has a similar construction (hence the legendary "hundreds of different words for snow"); I gather that in such languages, trying to figure out "the longest word" is like trying to figure out "the longest phrase" in English. We haven't many words for snow, but limitless phrases you can construct to describe it: old snow, new snow, clean snow, dirty snow, nasty yellow snow drilled full of holes from visiting dogs .... that last phrase there has probably never before been uttered or typed in English exactly that way, before I did so just now.

Don't forget Frank Zappa's classic medley "Don't Eat the Yellow Snow/Nanook Rubs It"

And she said, with a tear in her eye
Watch out where the huskies go, and don't you eat that yellow snow
Watch out where the huskies go, and don't you eat that yellow snow

That got me just about as evil as an eskimo boy can be. so I bent down
And I reached down, and I scooped down and I gathered up a generous
Mitten-ful of the deadly yellow snow

The deadly yellow snow, from right there where the huskies go!

Whereupon I proceeded to take that mittenful of the deadly yellow snow
Crystals and rub it all into his beady little eyes with a vigorous
Circular motion hitherto unknown to the people of this area, but destined
To take the place of the mudshark in your mythology
Here it goes,the circular motion, now rub it!

(Here fido)

And then
In a fit of anger
I pounced

And I pounced again

Great googly moogly!

I jumped up and down on the chest of the him

I injured
The fur trapper

Well he was very upset, as you can understand
And rightly so, because the
Deadly yellow snow crystals had
Deprived him of his
Sight

I am reminded of my new favorite Bible verse, Isiah 56:12:
"Come," they say, "let's get some wine and have a party. Let's all get drunk. Then tomorrow we'll do it again and have an even bigger party!"
