No Worries

You see this phrase a lot in texts. Sometimes in emails. The meaning is obvious. Or is it?

My question is, is it really from Australia? And if so, how did it become an artifact of the email/texting technology? A part of Internet slang.

Just because it’s short?

Well?

“Parachuting” cats

British anthrozoologist John Bradshaw in his 2014 feline science book Cat Sense reports how cats can survive falls from tall buildings and trees by performing an intricate midair ballet. Their “gravity-detecting” bio systems cause the forelegs and hind legs to rotate to point downward as they fall.

Then “…forming a ‘parachute’ by spreading all four legs out sideways, before adopting the landing position at the last minute. Laboratory simulations suggest that this limits the falling speed to a maximum of fifty-three miles per hour. This tactic apparently allows some cats to survive falls from high buildings with only minor injuries.”

Some cats also counter-rotate their tails fast, like a helicoptor, to stabilize their fall “…while the back is arched to cushion the landing.” Pretty clever, those cats.

The renewable energy shuck

“Even if one were to electrify all of transport, industry, heating and so on, so much renewable generation and balancing/storage equipment would be needed to power it that astronomical new requirements for steel, concrete, copper, glass, carbon fibre, neodymium, shipping and haulage etc etc would appear.

All these things are made using mammoth amounts of energy: far from achieving massive energy savings, which most plans for a renewables future rely on implicitly, we would wind up needing far more energy, which would mean even more vast renewables farms – and even more materials and energy to make and maintain them and so on. The scale of the building would be like nothing ever attempted by the human race.”

Whereas the global warming climate change hysteria is just the latest of its kind: doomsayers like our Little Barry Hussein, Bernie & the Hildabeast pronouncing their latest doom unless we consume less, pay more taxes, and give more power to the feckless government and its elites. You could bet their lives wouldn’t change.

Porn the spur of high-speed Internet?

What think ye, me hearties? Is it true, as some says, that on-line Porn is what really led to the demand for high-speed Internet? That Netflix, et al, came later?

Porn. Is there any positive economic development it can’t drive forward?

Launch. Land. Repeat.

“Blue Origin just launched and landed its suborbital rocket New Shepard — the same vehicle the company flew and then landed in November. The booster reached a maximum altitude of 333,582 feet, or 63 miles, above the Earth’s surface, before landing gently back at Blue Origin’s test facility in Texas. That makes it the first commercial vertical rocket to launch into space a second time.

This is becoming routine. Finally.

Adios, Ziggy Street

The city government played along for a while. Then they got serious.

Yesterday they removed the David Bowie street sign that Ziggy Stardust fans had got up in place of Bowie Street, an apparent reference to slave dealer and Alamo icon James Bowie, though the history on the original sign is unclear.

The change was less about slavery than about the rocker who finally fell to earth the other day, dead at 69 from cancer, the great destroyer.

Nice try, Ziggy fans. Keep pushing the formal petition. You never know, what with the slavery angle in a city as politically correct as Austin, you just might succeed. After all, Ziggy already has a whole constellation to himself.

Too funny, too true

antitheft

Got this from sportswriter friend Cedric Golden of the daily. Made me laugh. Reminded me of the mechanic the other day at the dealership who was amazed at the 5-speed in my Honda CRV. Hardly ever see them, he said, but he heard they were fun to drive. If you know how, sure. Even Mr. B.’s driving lessons are strictly with an automatic. Manual is a complete mystery to him.
