TL;DR: An Amazon driver wearing mishears an innocuous automated smart door bell response, tells Amazon that homeowner is racist, and Amazon incorrectly bans him from all Amazon products and services.

Possibly a stupid question, but how do I add functionality to the back button in Android without reimplementing the back button entirely nowadays?

Prior to last year, I would just call onBackPressed() and then simply override it:

override fun onBackPressed() {
	super.onBackPressed()

	doMyStuff()
}

It looks like this is now deprecated, and it's recommended to use OnBackPressedCallback objects. It's simple enough to replace onBackPressed() with onBackPressedDispatcher.onBackPressed(), but I can't figure out how to recreate the override.

I can replace the functionality easy enough:

override fun onCreate(savedInstanceState: Bundle?) {
	super.onCreate(savedInstanceState)
	…
	onBackPressedDispatcher.addCallback(this, object : OnBackPressedCallback(true) {
		doMyStuff()
	})
}

However, this replaces all back button behavior. It doesn't just add to it, despite the function name. I still want the back button to go back, but don't want to have to try to reinvent the wheel. Is there some equivalent to super.onBackPressed() with this new API or another way to achieve this?

On the other hand, apparently the Italians loved him:

In Ferrazzano, the village which De Niro's great grandparents left in search of the US dream in the late 19th century, most of its 3,280 residents are among his greatest fans and are adamant that he should be formally made an Italian. He does not officially qualify for a passport because neither his parents nor his grandparents were Italian born.

De Niro was born in New York in 1943, and has never visited the village.

Every August for eight years, the village's now wealthy population of lawyers, doctors and office workers, most of who commute to work in the nearby town of Campobasso, has turned out for a week long festival of De Niro films.

The Big Mac index started as a joke, but became a somewhat respectable—if still highly informal—way of measuring Purchasing Power Parity. Argentina took advantage of this by making it really cheap but hiding it so no one would order it, artificially improving the country's score.

Hence why they're called tread-"mills"—they were used to power mills to pump water or grind grain.
