There’s an eyebrow-raising technology buried inside millions of Amazon Echo smart speakers and Ring security cameras. They have the ability to make a new kind of wireless network called Sidewalk that shares a slice of your home Internet connection with your neighbors’ devices.
And on Tuesday, Amazon is switching Sidewalk on — for everyone.
I’m digging into my settings to turn it off. Sidewalk raises more red flags than a marching band parade: Is it secure enough to be activated in so many homes? Are we helping Amazon build a vast network that can be used for more surveillance? And why didn’t Amazon ask us to opt-in before activating a capability lying dormant in our devices?
I recommend you opt-out of Sidewalk, too, until we get much better answers to these questions.

A year ago, as the pandemic ravaged country after country and economies shuddered, consumers were the ones panic-buying. Today, on the rebound, it’s companies furiously trying to stock up.
Mattress producers to car manufacturers to aluminum foil makers are buying more material than they need to survive the breakneck speed at which demand for goods is recovering and assuage that primal fear of running out. The frenzy is pushing supply chains to the brink of seizing up. Shortages, transportation bottlenecks, and price spikes are nearing the highest levels in recent memory, raising concern that a supercharged global economy will stoke inflation.
Copper, iron ore, and steel. Corn, coffee, wheat, and soybeans. Lumber, semiconductors, plastic, and cardboard for packaging. The world is seemingly low on all of it. “You name it, and we have a shortage on it,” Tom Linebarger, chairman, and chief executive of engine and generator manufacturer Cummins Inc., said on a call this month. Clients are “trying to get everything they can because they see high demand,” Jennifer Rumsey, the Columbus, Indiana-based company’s president, said. “They think it’s going to extend into next year.”

When the Navy pilot first spotted the strange object hovering in restricted airspace off the Atlantic Coast, he was stunned — no exhaust plume, no visible engine, and all the makings of something secret, something mysterious or something dangerous.
But years later, Ryan Graves sounded almost bored as he recounted for a national television audience his history with unidentified aerial phenomena — UAPs, better known as UFOs.
Perhaps because for him and some of his former Navy colleagues, such sightings became a regular occurrence.
“Every day,” Graves said in an interview with CBS’s “60 Minutes” that aired Sunday. “Every day for at least a couple years.”
The retired lieutenant’s matter-of-fact remark stopped “60 Minutes” correspondent Bill Whitaker, who cut in: “Wait a minute. Every day for a couple of years?”

We can tell how much matter is in the universe by the motions of the stars. In the1920s, physicists attempting to do so discovered a discrepancy and concluded that there must be more matter in the universe than is detectable. How can this be?
In 1933, Swiss astronomer Fritz Zwicky, while observing the motion of galaxies in the Coma Cluster, began wondering what kept them together. There wasn’t enough mass to keep the galaxies from flying apart. Zwicky proposed that some kind of dark matter provided cohesion. But since he had no evidence, his theory was quickly dismissed.
Then, in 1968, astronomer Vera Rubin made a similar discovery. She was studying the Andromeda Galaxy at Kitt Peak Observatory in the mountains of southern Arizona when she came across something that puzzled her. Rubin was examining Andromeda’s rotation curve or the speed at which the stars around the center rotate, and realized that the stars on the outer edges moved at the exact same rate as those at the interior, violating Newton’s laws of motion. This meant there was more matter in the galaxy than was detectable. Her punch card readouts are today considered the first evidence of the existence of dark matter.
Many other galaxies were studied throughout the ’70s. In each case, the same phenomenon was observed. Today, dark matter is thought to comprise up to 27% of the universe. “Normal” or baryonic matter makes up just 5%. That’s the stuff we can detect. Dark energy, which we can’t detect either, makes up 68%.

There’s one line from Twitter power user Chrissy Teigen’s latest mea culpa that I haven’t been able to get out of my head. Teigen, who recently returned to the platform less than a month after announcing she was quitting it forever, tweeted an apology to media personality Courtney Stodden, who had accused her of harassing them online when they were just 16 years old.
“I’m mortified and sad at who I used to be,” Teigen wrote to her 13.6 million followers last week. “I was an insecure, attention-seeking troll. I am ashamed and completely embarrassed at my behavior but that is nothing compared to how I made Courtney feel.”
It was the next bit, though, that’s been haunting me: “I have worked so hard to give you guys joy and be beloved and the feeling of letting you down is nearly unbearable.” There’s something deeply telling about Teigen’s admission that she works hard to “be beloved” — which, as writer Bolu Babalola notes, “is not the same as working to be a good person.”
The vast majority of people on social media aren’t mega-celebrities attempting to charm ginormous audiences while also carrying on strange and vicious vendettas. But Teigen’s failure to leave a site that makes her feel terrible — and her bald-faced attempts to “be beloved,” which tend to backfire spectacularly — are emblematic of how a lot of people have felt about social media lately, and especially over this past year.

Most folks love learning, regardless of whether or not school is “their thing.” Sometimes it’s just a matter of finding the right teacher for your learning style—or maybe even the right medium.
For auditory learners, podcasts can be excellent vehicles for processing knowledge that’d be less digestible in more visual mediums like video or even the written word. The American education systems tends to fail students in myriad ways, requiring continual education after the fact to learn the truth behind what we were taught in history, art, science, language, literature, and math. Privileged gatekeepers deciding who and what gets taught can result in the denial of diverse voices and perspectives.
Podcasts radically shift the dynamics around who gets to teach, and who gets to learn. A lot of the most beloved and popular shows, like Radiolab and Dan Carlin’s Hardcore History, basically boil down to what you wish your science or history class had been like in the first place. Many others, like 1619 and You’re Wrong About, aim to correct the misinformation in many accepted cultural narratives from both our near and distant pasts.
Now, obviously, podcasts can’t replace a world-class, bonafide, IRL, teacher-to-student relationship. But they can teach us more than a few vital lessons.

Listen, and you might learn a thing or two.

Last month, government officials in the island nation of the Maldives officially unveiled plans to build the first fully floating island city of its kind. Could the ambitious experiment be a blueprint for how we’ll live in the future as climate change continues to raise the global sea level?
As “arguably the lowest-lying country in the world,” according to NASA—the average elevation is just 3.3 feet above sea level—the Maldives, an island republic in the northern Indian Ocean, will soon have to rely on sustainable housing. In virtually any simulation of the near future, the over 1,000 individual islands that make up the Maldives will be some of the first to disappear below the rising sea level.
Enter the floating city, appropriately called Maldives Floating City (MFC), which will be built in a lagoon just minutes from Male, the capital of the Maldives. MFC’s designers—the Netherlands-based Dutch Docklands, the global leader in floating infrastructure—say the floating city’s shape, a series of honeycomb-like hexagonal maze rows is supposed to resemble coral.
