Amazon Ring security camera is viewed on a tablet
- Speaking at Web Summit 2020, David Limp, the senior vice president of Devices and Services at Amazon, suggested that the company is aiming to build smart devices that would operate in neighborhoods.
- Amazon recently began rolling out Sidewalk, which aims to create a shared, intermediate-range network powered by Amazon devices.
- Sidewalk, which lets nearby devices access your Wi-Fi, raises numerous privacy and security concerns.
If you say "Alexa" right now, there's a decent chance you'll activate one of the more than 100 million Amazon Echo devices the company has sold since 2014. Today, one in four adults in the U.S. own a smart speaker and surveys suggest a majority of American households now own at least one smart-home product. Globally, the smart-home market is projected to nearly double from $78 billion in 2020 to $135 billion in 2025.
As these devices become fixtures in homes, are neighborhoods next?
When asked about the future of Amazon devices at Web Summit 2020, here was the response from David Limp, the senior vice president of Devices and Services at Amazon:
"I won't outline the complete roadmap, but I will tell you, we start seeing extending outward from the home," Limp said.
The two "most obvious" places Amazon has its sights on: neighborhoods and cars, according to Limp. What might the neighborhood aspect look like? It's unclear exactly how Amazon sees the future of devices in public or private-community spaces, but Amazon's new Sidewalk network provides clues.
Amazon Sidewalk
Sidewalk, which began rolling out in the U.S. in November, aims to create a shared network powered by Amazon devices. It's something like a community of Wi-Fi hotspots to which compatible devices can automatically connect.
Amazon Echo and Ring devices would serve as so-called Sidewalk Bridges that "share a small portion of your internet bandwidth which is pooled together to provide these services to you and your neighbors," Amazon writes.
Say you have a security camera in your detached garage that's not working because it's just out of your router's range. With Sidewalk, it'd be able to siphon off some of the Wi-Fi connection emitted from your neighbor's devices (if they enable Sidewalk). But that also means you'd be offering up some of your Wi-Fi bandwidth (500mb monthly maximum) to any compatible devices within about a half-mile.
Amazon frames Sidewalk as a sort of first step toward creating smart neighborhoods that utilize the so-called internet of things:
"When your device is connected to the Sidewalk network, you can connect to Alexa and offer more experiences for customers like keeping track of the things they care about most, whether it's their puppy, their keys, or their bicycle. Later this year, Tile devices will be supported on the Sidewalk network, enabling customers to keep track of their things by asking Alexa questions like 'Alexa, where are my keys?'"
Amazon
When Amazon first announced Sidewalk in 2019, CEO Jeff Bezos told reporters the system would fill a gap in wireless connectivity:
"It's a completely new way of thinking about intermediate-range wireless. There are a lot of things where Bluetooth is way too short-range, WiFi is way too high power, and so to have something that's still low-power, but that has much longer range is really a gap in the marketplace. [...] People don't even realize yet how important that intermediate range is going to be."
On the neighborhood level, this could prove convenient for people with compatible devices, as Jonathan Collins, research director at ABI Research, told Cities Today:
"Amazon Sidewalk has the potential to deliver low-cost, low-data, citywide mesh connectivity. It could certainly benefit from adoption within smart-city projects. For example, integrating Sidewalk into parking meters would bring low-cost network access for the city, but it will also provide more mesh nodes to strengthen network coverage and capacity."
Security concerns
Sidewalk raises no shortage of red flags in terms of security and privacy.
"The initial concern is really about what all the devices connected to Sidewalk collect," Forrester security analyst Jeff Pollard told CNET. "If use cases like home automation or IoT devices make use of this technology, they generate telemetry data. Connected devices -- especially in the home -- give vast amounts of information about your behaviors and activities, which could also go to Amazon with this connectivity."
I’m freaking out about this Amazon Sidewalk mesh network stuff. Here’s why: 1. Amazon is pushing WiFi so you have… https://t.co/E0S9EMT4KD— Liz O’Sullivan (@Liz O’Sullivan)1569511661.0
In addition to Amazon potentially learning more about your behaviors, Sidewalk could create vulnerabilities for outside parties to exploit. After all, hackers have already been able to gain access to Echo speakers and Ring cameras, and in 2019 Gizmodo reporters were able to map the "potential locations of up to tens of thousands of Ring cameras."

Amazon
Anticipating concerns, Amazon published a white paper describing how Sidewalk uses three layers of encryption, doesn't reveal users' identities, and makes "it difficult for anyone, including Amazon, to piece together [a user's] activity history over time."
Difficult, but not impossible. Amazon said it's automatically enabling Sidewalk on Echo and Ring devices, though users can opt-out of the system. If you'd rather not serve as a guinea pig in Amazon's new shared network, here's how to disable it:

Ash deposits of some of North America's largest volcanic eruptions.
The end of the world as we know it

Of the many freak ways to shuffle off this mortal coil – lightning strikes, shark bites, falling pianos – here's one you can safely scratch off your worry list: an outbreak of the Yellowstone supervolcano.
As the map below shows, previous eruptions at Yellowstone were so massive that the ash fall covered most of what is now the western United States. A similar event today would not only claim countless lives directly, but also create enough subsidiary disruption to kill off global civilisation as we know it. A relatively recent eruption of the Toba supervolcano in Indonesia may have come close to killing off the human species (see further below).
However, just because a scenario is grim does not mean that it is likely (insert topical political joke here). In this case, the doom mongers claiming an eruption is 'overdue' are wrong. Yellowstone is not a library book or an oil change. Just because the previous mega-eruption happened long ago doesn't mean the next one is imminent.

This map shows the location of the Yellowstone plateau and the ash beds deposited by its three most recent major outbreaks, plus two other eruptions – one similarly massive, the other the most recent one in North America.
Huckleberry Ridge
The Huckleberry Ridge eruption occurred 2.1 million years ago. It ejected 2,450 km3 (588 cubic miles) of material, making it the largest known eruption in Yellowstone's history and in fact the largest eruption in North America in the past few million years.
This is the oldest of the three most recent caldera-forming eruptions of the Yellowstone hotspot. It created the Island Park Caldera, which lies partially in Yellowstone National Park, Wyoming and westward into Idaho. Ash from this eruption covered an area from southern California to North Dakota, and southern Idaho to northern Texas.
Mesa Falls
About 1.3 million years ago, the Mesa Falls eruption ejected 280 km3 (67 cubic miles) of material and created the Henry's Fork Caldera, located in Idaho, west of Yellowstone.
It was the smallest of the three major Yellowstone eruptions, both in terms of material ejected and area covered: 'only' most of present-day Wyoming, Colorado, Kansas and Nebraska, and about half of South Dakota.
Lava Creek
The Lava Creek eruption was the most recent major eruption of Yellowstone: about 640,000 years ago. It was the second-largest eruption in North America in the past few million years, creating the Yellowstone Caldera.
It ejected only about 1,000 km3 (240 cubic miles) of material, i.e. less than half of the Huckleberry Ridge eruption. However, its debris is spread out over a significantly wider area: basically, Huckleberry Ridge plus larger slices of both Canada and Mexico, plus most of Texas, Louisiana, Arkansas, and Missouri.
Long Valley
This eruption occurred about 760,000 years ago. It was centered on southern California, where it created the Long Valley Caldera, and spewed out 580 km3 (139 cubic miles) of material. This makes it North America's third-largest eruption of the past few million years.
The material ejected by this eruption is known as the Bishop ash bed, and covers the central and western parts of the Lava Creek ash bed.
Mount St Helens
The eruption of Mount St Helens in 1980 was the deadliest and most destructive volcanic event in U.S. history: it created a mile-wide crater, killed 57 people and created economic damage in the neighborhood of $1 billion.
Yet by Yellowstone standards, it was tiny: Mount St Helens only ejected 0.25 km3 (0.06 cubic miles) of material, most of the ash settling in a relatively narrow band across Washington State and Idaho. By comparison, the Lava Creek eruption left a large swathe of North America in up to two metres of debris.
The difference between quakes and faults
The volume of dense rock equivalent (DRE) ejected by the Huckleberry Ridge event dwarfs all other North American eruptions. It is itself overshadowed by the DRE ejected at the most recent eruption at Toba (present-day Indonesia). This was one of the largest known eruptions ever and a relatively recent one: only 75,000 years ago. It is thought to have caused a global volcanic winter which lasted up to a decade and may be responsible for the bottleneck in human evolution: around that time, the total human population suddenly and drastically plummeted to between 1,000 and 10,000 breeding pairs.

So, what are the chances of something that massive happening anytime soon? The aforementioned mongers of doom often claim that major eruptions occur at intervals of 600,000 years and point out that the last one was 640,000 years ago. Except that (a) the first interval was about 200,000 years longer, (b) two intervals is not a lot to base a prediction on, and (c) those intervals don't really mean anything anyway. Not in the case of volcanic eruptions, at least.
Earthquakes can be 'overdue' because the stress on fault lines is built up consistently over long periods, which means quakes can be predicted with a relative degree of accuracy. But this is not how volcanoes behave. They do not accumulate magma at constant rates. And the subterranean pressure that causes the magma to erupt does not follow a schedule.
What's more, previous super-eruptions do not necessarily imply future ones. Scientists are not convinced that there ever will be another big eruption at Yellowstone. Smaller eruptions, however, are much likelier. Since the Lava Creek eruption, there have been about 30 smaller outbreaks at Yellowstone, the last lava flow being about 70,000 years ago.
As for the immediate future (give or take a century): the magma chamber beneath Yellowstone is only 5 percent to 15 percent molten. Most scientists agree that is as un-alarming as it sounds. And that its statistically more relevant to worry about death by lightning, shark, or piano.

Stoicism can help overcome anxiety
Are you a worrier? Do you imagine nightmare scenarios and then get worked up and anxious about them? Does your mind get caught in a horrible spiral of catastrophizing over even the smallest of things? Worrying, particularly imagining the worst case scenario, seems to be a natural part of being human and comes easily to a lot of us. It's awful, perhaps even dangerous, when we do it.
But, there might just be an ancient wisdom that can help. It involves reframing this attitude for the better, and it comes from Stoicism. It's called "premeditation," and it could be the most useful trick we can learn.
Practical Stoicism
Broadly speaking, Stoicism is the philosophy of choosing your judgments. Stoics believe that there is nothing about the universe that can be called good or bad, valuable or valueless, in itself. It's we who add these values to things. As Shakespeare's Hamlet says, "There is nothing either good or bad, but thinking makes it so." Our minds color the things we encounter as being "good" or "bad," and given that we control our minds, we therefore have control over all of our negative feelings.
Put another way, Stoicism maintains that there's a gap between our experience of an event and our judgment of it. For instance, if someone calls you a smelly goat, you have an opportunity, however small and hard it might be, to pause and ask yourself, "How will I judge this?" What's more, you can even ask, "How will I respond?" We have power over which thoughts we entertain and the final say on our actions. Today, Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."
One of the principal fathers of ancient Stoicism was the Roman statesmen, Seneca, who argued that the unexpected and unforeseen blows of life are the hardest to take control over. The shock of a misfortune can strip away the power we have to choose our reaction. For instance, being burglarized feels so horrible because we had felt so safe at home. A stomach ache, out of the blue, is harder than a stitch thirty minutes into a run. A sudden bang makes us jump, but a firework makes us smile. Fell swoops hurt more than known hardships.
What could possibly go wrong?
So, how can we resolve this? Seneca suggests a Stoic technique called "premeditatio malorum" or "premeditation." At the start of every day, we ought to take time to indulge our anxious and catastrophizing mind. We should "rehearse in the mind: exile, torture, war, shipwreck." We should meditate on the worst things that could happen: your partner will leave you, your boss will fire you, your house will burn down. Maybe, even, you'll die.
This might sound depressing, but the important thing is that we do not stop there.
Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."
The Stoic also rehearses how they will react to these things as they come up. For instance, another Stoic (and Roman Emperor) Marcus Aurelius asks us to imagine all the mean, rude, selfish, and boorish people we'll come across today. Then, in our heads, we script how we'll respond when we meet them. We can shrug off their meanness, smile at their rudeness, and refuse to be "implicated in what is degrading." Thus prepared, we take control again of our reactions and behavior.
The Stoics cast themselves into the darkest and most desperate of conditions but then realize that they can and will endure. With premeditation, the Stoic is prepared and has the mental vigor necessary to take the blow on the chin and say, "Yep, l can deal with this."
Catastrophizing as a method of mental inoculation
Seneca wrote: "In times of peace, the soldier carries out maneuvers." This is also true of premeditation, which acts as the war room or training ground. The agonizing cut of the unexpected is blunted by preparedness. We can prepare the mind for whatever trials may come, in just the same way we can prepare the body for some endurance activity. The world can throw nothing as bad as that which our minds have already imagined.
Stoicism teaches us to embrace our worrying mind but to embrace it as a kind of inoculation. With a frown over breakfast, try to spend five minutes of your day deliberately catastrophizing. Get your anti-anxiety battle plan ready and then face the world.

How to get people to want to give you money, literal balls of cash not gaurenteed.
Even the best charities with the longest records of doing great fundraising work have to spend some time making sure that the next donation checks will keep coming in. One way to do this is by showing potential donors all the good things the charity did over the previous year. But there may be a better way.
A new study by researchers in the United States and Australia suggests that appealing to the benefits people will receive themselves after a donation nudges them to donate more money than appealing to the greater good.
How to get people to give away free money
The study, published in Nature Human Behaviour, utilized the Pick.Click.Give program in Alaska. This program allows Alaska residents who qualify for dividends from the Alaska Permanent Fund, a yearly payment ranging from $800 to $2000 in recent years, to donate a portion of it to various in-state non-profit organizations.
The researchers randomly assigned households to either a control group or to receive a postcard in the mail encouraging them to donate a portion of their dividend to charity. That postcard could come in one of two forms, either highlighting the benefits to others or the benefits to themselves.
Those who got the postcard touting self-benefits were 6.6 percent more likely to give than those in the control group and gave 23 percent more on average. Those getting the benefits-to-others postcard were slightly more likely to give than those receiving no postcard, but their donations were no larger.
Additionally, the researchers were able to break the subject list down into a "warm list" of those who had given at least once before in the last two years and a "cold list" of those who had not. Those on the warm list, who were already giving, saw only minor increases in their likelihood to donate after getting a postcard in the mail compared to those on the cold list.
Additionally, the researchers found that warm-list subjects who received the self-interest postcard gave 11 percent more than warm-list subjects in the control group. Amazingly, among cold-list subjects, those who received a self-interest postcard gave 39 percent more.
These are substantial improvements. At the end of the study, the authors point out, "If we had sent the benefits to self message to all households in the state, aggregate contributions would have increased by nearly US$600,000."
To put this into perspective, in 2017 the total donations to the program were roughly $2,700,000.
Is altruism dead?
Are all actions inherently self-interested? Thankfully, no. The study focuses entirely on effective ways to increase charitable donations above levels that currently exist. It doesn't deny that some people are giving out of pure altruism, but rather that an appeal based on self-interest is effective. Plenty of people were giving before this study took place who didn't need a postcard as encouragement. It is also possible that some people donated part of their dividend check to a charity that does not work with Pick.Click.Give and were uncounted here.
It is also important to note that Pick.Click.Give does not provide services but instead gives money to a wide variety of organizations that do. Those organizations operate in fields from animal rescue to job training to public broadcasting. The authors note that it is possible that a more specific appeal to the benefits others will receive from a donation might prove more effective than the generic and all-inclusive "Make Alaska Better For Everyone" appeal that they used.
In an ideal world, charity is its own reward. In ours, it might help to remind somebody how warm and fuzzy they'll feel after donating to your cause.
