Lewis’s Woodpecker

American Bird Conservancy has changed its page. It seems even easier to use. Here are some bits about this week’s bird.

About

Most woodpecker species in the United States and Canada display a mix of black, white, and red plumage, but don’t tell the Lewis’s Woodpecker. Its unusual mix of colors includes a red face, pink belly, glossy green back, crown, and nape, and silver-gray collar. The bird is simply stunning.

Lewis’s Woodpecker also differs from other members of its family in many of its foraging styles and food choices. In the summer, the bird eats mostly insects, catching them in flight by swooping out from a perch like a flycatcher or by foraging in flight like a swallow. Wide, rounded wings give the bird a buoyant, straight-line flight, more like a jay or crow than a woodpecker. The bird seldom excavates for wood-boring insects; unlike other woodpeckers, this species lacks the strong head and neck muscles needed to drill into hard wood.

In the fall, Lewis’s Woodpeckers switch to eating nuts and fruit, chopping up acorns and other nuts and caching them in bark crevices for later consumption. During the winter, they aggressively guard these storage areas against intruders, including other woodpecker species. 

Ornithologist Alexander Wilson described the species in 1811 and named it for Meriwether Lewis, who observed the bird in 1805 during the Lewis and Clark expedition. 

Threats

Birds around the world are declining, and many of them, like Lewis’s Woodpecker, are facing urgent, acute threats. Moreover, all birds, from the rarest species to familiar backyard birds, are made more vulnerable by the cumulative impacts of threats like habitat loss and invasive species.

Habitat Loss

Surveys indicate that Lewis’s Woodpecker populations may have declined by about 60 percent since the 1960s, and much of the reduction is likely due to loss or alteration of suitable nesting habitat. Like all other woodpeckers, the Lewis’s Woodpecker requires cavities in snags (standing, dead, or partly dead trees) for nesting. Logging, the suppression of wildfires, and grazing have altered many of the western forests where the species is found. The changes to the landscape often result in large areas dominated by trees that are the same age, leaving few dead or decaying trees available for the birds’ nests.

Habitat Loss

Pesticides & Toxins

Pesticides take a heavy toll on birds in a variety of ways. Birds can be harmed by direct poisoning from pesticides, lose insect prey to pesticides sprayed on crops and lawns, or be slowly poisoned by ingesting small mammal prey that have themselves ingested rodenticides. Lewis’s Woodpeckers are likely exposed to pesticides in orchards and other agricultural settings.

Norway Turns Ocean Forests Of Seaweed Into Weapons Against Climate Change

Written by Matthew Russell

Off Trøndelag’s coast, long lines of kelp now do double duty. They grow fast. They also lock away carbon. A new pilot farm near Frøya aims to turn that promise into measurable removal of CO₂ from the air, according to DNV.

The site spans 20 hectares and carries up to 55,000 meters of kelp lines. First seedlings went in last November. The goal is proof of concept, then scale.

How the Pilot Works

The three-year Joint Industry Project, JIP Seaweed Carbon Solutions, brings SINTEF together with DNV, Equinor, Aker BP, Wintershall Dea, and Ocean Rainforest, with a total budget of NOK 50 million, Safety4Sea reports.

Researchers expect an initial harvest of about 150 tons of kelp after 8–10 months at sea. Early estimates suggest that biomass could represent roughly 15 tons of captured CO₂. This is a test bed for methods that can be replicated and expanded, DNV explains.

There’s a second step, as kelp becomes biochar. That process stabilizes carbon for the long term and can improve soils on land, SINTEF’s team told Safety4Sea. The project is designed to test both the removal and the storage.

A Long History, A New Mission

Seaweed isn’t new here. Norwegians have cultivated kelp since the 18th and 19th centuries for fertilizer and feed. Scientists advanced modern methods in the 1930s, laying the groundwork for today’s farms, according to SeaweedFarming.com. Cold, nutrient-rich waters support species like Laminaria and Saccharina. They grow quickly and draw down dissolved carbon and nitrogen.

The country’s aquaculture backbone also helps. Norway already runs one of the world’s most advanced seafood sectors. That expertise now extends to macroalgae.

Policy, Permits, and Ecosystems

Commercial cultivation began receiving specific permits in 2014, and activity has expanded across several coastal counties, according to a study in Aquaculture International. Researchers detailed the risks that accompany scale: genetic interaction with wild kelp, habitat impacts, disease, and space conflicts. Integrated Multi-Trophic Aquaculture, where seaweed grows alongside finfish, can recycle nutrients from farms and reduce eutrophication pressures.

Vibrant yellow seaweed covers dark rocky surfaces near shallow water.

Engineering for Open Water

Getting beyond sheltered bays is crucial. One path is the “Seaweed Carrier,” a sheet-like offshore system that lets kelp move with waves in deeper, more exposed water. It supports mechanical harvesting and industrial output without using land, Business Norway explains. The same approach can enhance water quality by absorbing CO₂ and “lost” nutrients.

The Frøya project is small in tonnage but big in intent. It links Norway’s long kelp lineage with new climate tech: fast-growing macroalgae, verified carbon accounting, and durable storage as biochar. If these methods prove reliable at sea and on shore, Norway will have more than a farm. It will have a blueprint for ocean-based carbon removal that others can copy.

A Date & An SoS That Will Live In Infamy, 1st Airplane Takeoff From A Ship, & 10 Million Did Not Sign, On This Date In Peace & Justice History

November 14, 1910
Eugene Ely performed the first airplane takeoff from a ship. His Curtiss pusher flew from the deck of the U.S.S. Birmingham in Hampton Roads, Virginia.By January he would execute the first (takeoff and) landing on a warship, the U.S.S. Pennsylvania. Captain Washington I. Chambers of the Navy Department had been interested in the military uses for the seven-year-old invention.
Naval flight training started shortly thereafter.

November 14, 1954
“Ten Million Americans Mobilized for Justice” began a campaign to collect 10 million signatures on a petition urging the Senate not to censure Senator Joseph McCarthy (R-Wisconsin). The motion of censure against Senator McCarthy was for obstructing a Senate committee and for acting inexcusably and reprehensibly toward a U.S. soldier appearing before his own committee.
McCarthy had used his Senate Permanent Investigations Subcommittee to publicly denounce thousands as subversive, especially within the federal government, many without any justification. The political views of most were painted as treasonable and conspiratorial, rather than differing political views.
The petition effort fell about nine million signatures short.

Explanation: Few cosmic vistas can excite the imagination like The Great Nebula in Orion. Visible as a faint, bland celestial smudge to the naked-eye, the nearest large star-forming region sprawls across this sharp colorful telescopic image. Designated M42 in the Messier Catalog, the Orion Nebula’s glowing gas and dust surrounds hot, young stars. About 40 light-years across, M42 is at the edge of an immense interstellar molecular cloud only 1,500 light-years away that lies within the same spiral arm of our Milky Way galaxy as the Sun. Including dusty bluish reflection nebula NGC 1977, also known as the Running Man nebula at left in the frame, the natal nebulae represent only a small fraction of our galactic neighborhood’s wealth of star-forming material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems.

Detransition is key to politicians’ anti-trans agenda. But what is it really like?

Nov 12, 2025 Orion Rummler

This story was originally reported by Orion Rummler of The 19th. Meet Orion and read more of his reporting on gender, politics and policy.

For some people, gender shifts over time, often through changes in one’s sense of self. A transgender man may realize they are nonbinary and stop hormone replacement therapy. A trans woman may face so much discrimination that she represses her identity. And some trans people medically reverse their transition to live as their sex assigned at birth. 

These experiences are all part of a process known as detransitioning. Although detransitioning does not have a consistent social or academic definition, it generally applies to someone who has sought a gender transition and then stopped, shifted or reversed aspects of it. Their experiences offer a deeper look at how discrimination and gender norms impact our lives, how gender-affirming care can be improved, and how identity is perhaps more fluid than previously thought. 

As experts work to understand detransitioners, their vulnerabilities and their highly individualized needs, their identities are being co-opted as part of a national campaign against transgender rights. Health care access and research are being blocked by politicians for both trans people and detransitioners — while anti-trans rhetoric puts everyone at risk.

The Federal Trade Commission and the Justice Department are investigating gender-affirming care as medical fraud, and they are rooting this effort in detransitioners’ stories that fit the narrative the Trump administration wants to advance. The White House wants the National Institutes of Health to study “regret” and “detransition,” even as it cuts any federal funding for researchthat mentions the word “trans.” The U.S. Department of Education hosted a “Detrans Awareness Day” event last March. Meanwhile, its functions have been severely undermined by layoffs and budget cuts. 

The White House and agencies like the Justice Department claim that gender-affirming care is mutilating children, overlooking that young trans people live happily after transition and the studies showing that adolescents who regret transition are in the minority. Government officials describe trans people and detransitioners as victims of a medical conspiracy to boost profits and force gender ideology on families. Now, they are seeking evidence to prove those claims by subpoenaing hospitals for patients’ private data, including doctors’ notes, patient addresses and Social Security numbers.

Gender-affirming care has been broadly endorsed by the medical community for its effectiveness in treating gender dysphoria, a persistent distress felt when one’s body is out of sync with their identity. The 2022 U.S. Trans Survey, which polled over 92,000 trans and nonbinary people 16 and older, found that social and medical transition were profound sources of life satisfaction. Experts and advocates agree that more research and more understanding are needed to improve trans medical care. But under Trump, they also expect transgender and intersex health to keep getting worse, not better. 

The 19th spoke with two detransitioners who feel harmed and usedby the Trump administration, which has positioned itself as a protector of those who detransition. Adriana lives in New York City, where she feels safe to express herself among so many LGBTQ+ people, but has struggled to access adequate health care. Ara lives in North Carolina, a state that has several laws restricting trans rights and health care access — and where support from a mental health program and her partner has helped her navigate the challenges of detransitioning. As politicians stoke fear about gender non-conformity, their experiences offer a deeper understanding of what it means to live authentically in a politically volatile time. 

Still, more young people have been exploring their identities, expanding the boundaries of gender and adding to the cultural and social norms surrounding it. Detransitioners’ experiences are part of that social evolution. Their stories of regret and pain exist alongside stories of joy and empowerment — and these are all part of a journey of self-discovery that may have turned out to be more complicated than they initially thought. The question is, will elected officials support them on this journey or cause more harm?


‘Taking away trans health care is taking away people’s lives’

As providers of trans health care have become political targets, Ara Kareis’ own routine treatments have been disrupted.

‘I just feel like such a power source’

The joy that Adriana Del Orden feels in her body could have only come through exploring her gender. She’s tired of being told that she ruined her life.

The politics of detransition

Political rhetoric doesn’t capture the complexity of detransitioning — or what taking away health care means.

Health News Updates

Infant formula botulism cluster, black box warning for HRT, flu is waking up, new blood pressure guidelines, and more by Katelyn Jetelina

This is your weekly Dose. Read on Substack

The shutdown may finally be coming to an end. Our health care costs, unfortunately, will not. I’ll be back on Wednesday with a deep dive into just how spectacularly absurd our health care system has become.

In the meantime, RSV and flu are picking up speed, and a concerning infant formula recall has been linked to a rare botulism cluster, thanks to a small but mighty team in California. The FDA is expected to remove the black box warning from hormone replacement therapy—a move that’s scientifically sound but bound to spark drama from HHS. We also have new blood pressure guidelines that could make prevention a lot more personal. And amidst it all, a few more pieces of genuinely good news to end on a high note.

Let’s dive in!


Disease “weather” report: RSV and flu gaining momentum

It will take some time for the CDC data systems to ramp up again after being offline for over 40 days. For now, we’ll continue to rely on the alternative sources, such as Dr. Caitlin Rivers’ updates and the PopHive dashboards.

RSV continues to climb slowly but steadily, especially among children under five. National growth is still linear—not yet exponential—but that acceleration could occur at any time.

The flu remains relatively low but is beginning to increase, particularly among young children. As Dr. Rivers notes, “Hawaii has moved to moderate activity, Arizona has surpassed its seasonal baseline, and New York cases jumped 49% in the past week.”

Source: New York State Department of Health Respiratory Surveillance Report

U.S. childhood flu vaccination rates have dropped from 62% to 49% over the past five years. Last year saw one of the deadliest seasons on record, with 280 pediatric deaths—the highest since tracking began in 2004. About 90% of those children weren’t fully vaccinated. Our deadliest flu season came at a time of historically low vaccination rates, which can’t be a coincidence. We don’t yet know this season’s coverage, but if it falls further, we could be facing another tragic record.

Covid-19 remains in a lull, though we typically see a winter rise starting in mid-to-late November.

I’m really hoping these three viruses don’t peak simultaneously. Hospitals strain under just a bad flu season; I couldn’t imagine the “big three” all at the same time. Historically, their peaks have staggered, but given how little we truly understand about these overlapping patterns, that may have been more a matter of luck than a rule. Time will tell.

What this means for you: This is the best time to get vaccinated. It’s certainly not too late.


Infant formula outbreak and Listeria in pasta

Over the weekend, a troubling cluster of infant botulism cases was linked to ByHeart Whole Nutrition Infant Formula. Even during a government shutdown and an increasingly challenging environment, outbreak teams have been working around the clock to protect our most vulnerable.

What this is: Infant botulism is extremely rare but serious. It occurs when Clostridium botulinum spores—commonly found in soil, dust, and some foods—germinate in a baby’s intestines and release toxins that can paralyze muscles, interfere with breathing, and require intensive care. In a typical year, the U.S. sees 160–180 cases, often linked to environmental exposure or foods like honey. Even a small cluster of cases is a clear red flag.

What we know: Clostridium botulinum spores have been detected in ByHeart infant formula, resulting in the hospitalization of 13 infants across 10 states. The California Department of Public Health (CDPH) played a key role in identifying this cluster. CDPH is the only source in the world for BabyBIG—the lifesaving antitoxin—and manages all clinician calls and treatment distribution. Their team noticed a spike in requests and discovered that the affected infants all consumed the same formula brand, prompting an alert to CDC. Importantly, ByHeart produces just 1% of U.S. infant formula, so this alone is unlikely to cause a national shortage. (Be sure to sign up for YLE CA for a deeper dive this Thursday.)

What we don’t know: Epidemiologists are investigating whether contamination is truly confined to ByHeart or reflects a broader issue in the manufacturing or ingredient sourcing process.

What to do: Stop using ByHeart Whole Nutrition Infant Formula immediately. Retailers should pull it from shelves, including Amazon, Kroger, Walmart, Whole Foods, Target, and Sam’s Club.

There is also the ongoing Listeria outbreak associated with frozen pasta dishes, including some sold at Trader Joe’s and other grocery chains. We’ve covered this before, but according to the agency’s ongoing investigation, two more brands of food are linked to the outbreak. There’s a long list of recalled products you can find here. Throw out immediately.

In total, there have been 27 illnesses reported, 25 hospitalizations, and six deaths in 18 states since late September.

HRT ‘black box’ warning may be gone soon

Word is that the FDA will remove the black box warning from hormone replacement therapy (HRT) this week. (It may now be pushed back with the government reopening.) If this announcement reflects the HRT review conducted at HHS last month, it will likely be messy and riddled with inaccuracies. However, if you look at the science without the drama, removing the black label is not unreasonable.

The black box warning—the strictest warning label, meant for drugs with potentially life-threatening risks—was enacted after a 2002 Women’s Health Initiative study found increased risks of stroke and breast cancer. Since then, research has revealed crucial nuance: risks depend on timing, dose, and delivery. Starting HRT earlier, using low-dose or localized estrogen, and tailoring therapy to each woman can be both effective and safe.

What this story is really about: Menopause is universal, yet too often misunderstood. While the science continues to evolve, the major problem is that clinical practice and training have lagged far behind. Women deserve evidence-based care, informed clinicians, and the freedom to make choices rooted in both science and compassion. We are still far from what is needed for women.

New blood pressure guidelines

Major new blood pressure guidelines dropped for the first time in years.

At the center of the update is an enhanced assessment tool called the PREVENT calculator, developed by the American Heart Association. It’s designed to estimate a person’s 10-year risk of cardiovascular disease using factors like blood pressure, cholesterol, smoking, and diabetes. The model was built using data from 6.5 million U.S. adults aged 30 to 79, making it one of the most representative tools available.

Here’s what stands out:

  • A new threshold for medication. The key number to watch is 7.5%. If your 10-year risk of heart disease is at or above that level, physicians are now encouraged to consider medication even if your blood pressure hovers around 130/80 mmHg. If your risk is below that, lifestyle changes, like healthy eating, exercising, and better stress management, remain the first step.
  • A focus on home monitoring. The guidelines also emphasize checking blood pressure at home. Growing evidence shows that home readings may actually be more accurate predictors of long-term risk than in-office measurements. So spending $45 on an arm monitor if you have hypertension might be a great (even lifesaving!) idea.

What this means for you: This makes heart health more personalized than ever. You can calculate your own 10-year risk using the PREVENT calculator (although you will need some pretty specific numbers from your last blood panel). Regardless, aim for blood pressure readings below 130/80, and use these new tools to guide smarter—and earlier—prevention.


Good news!

Here are some of the great things worth highlighting:

  • The American Academy of Pediatrics (AAP) is standing up for science. The organization filed an updated lawsuit last week against HHS Secretary Robert F. Kennedy, Jr., asking a court to disband a panel (ACIP) appointed by RFK Jr. and to overturn recent decisions made by that panel. Then, to proceed under court supervision. The legal move is a direct push to restore expert-led vaccine policymaking.
  • The Vaccine Integrity Project (VIP) is stepping up on Hep B. With the next ACIP meeting coming up in early December, where the agenda will likely include the Hepatitis B vaccine for infants, the childhood vaccination schedule, and HPV—VIP, an independent group of scientists formed in response to waning trust in RFK Jr.’s ACIP, is conducting an evidence review ahead of what could be a contentious meeting. Their work helps ensure the science remains front and center.
  • Vaping among youth has seen a decline; but we still have a long way to go. A new study has found that the number of U.S. teens vaping has decreased overall. That’s progress. But among those who still do it, vaping is becoming more frequent and harder to quit—signs that use is shifting from experimentation toward dependence for some. If you have a teen who vapes, check out the EX Program, which is a free, anonymous text-messaging program designed specifically for young people who vape. There’s also SmokefreeTXT for Teens.

Question grab bag: You ask, we answer!

How long does the Covid-19 vaccine last? I got mine in September, do I need to get another?

study published last week confirmed what we’ve consistently seen: protection against Covid-19 wanes over time. A study of more than 1.8 million Americans from the previous season showed protection against infection and severe disease declined after 4-5 months. The findings underscore the benefit of getting a Covid-19 vaccine every six months, especially for adults over 65, who accounted for nearly 80% of hospitalizations in the study.

After No Kings, It’s Time to Escalate by Eric Blanc

We need bigger—and more disruptive—nonviolent campaigns that can go viral and peel away Trump’s pillars of support Read on Substack

American democracy is on the ropes. Trump and his billionaire backers are doing everything possible to transform our country into an authoritarian state like Hungary or Russia, where the trappings of institutional democracy mask brazen autocratic rule.

Our president’s sinking popularity numbers might not matter so much if his administration is either able to ignore electoral results or to distort the electoral map so badly that there’s almost no way to vote Republicans out.

Far too many Democrats and union leaders naively hoped that the courts would save us. But the Supreme Court has given a green light to Trump’s power grab, and it appears poised to overturn Section 2 of the Voting Rights Act, the last major legal roadblock to prevent Republicans from disenfranchising millions of Democrats and Black voters across the South.

Are we cooked? Trump would certainly like us to believe he’s unstoppable. Faced with the administration’s relentless offensive against immigrants, free speech, public services, and majoritarian rule, it’s normal to sometimes succumb to despair. But there’s no need to throw in the towel — and there are concrete next steps we can all take to win back the country through nonviolent resistance. As Chicago Teachers Union (CTU) president Stacy Davis Gates reminds us, Trumpism “won’t be stopped just in the courts or at the ballot box.” (snip-there is MORE on the page linked at “Read on Substack” above)

The introvert’s guide to fighting for democracy by Protect Democracy

Six ways to protect democracy — without attending a protest Read on Substack

If you’re reading this, you’re concerned about our democracy’s slide into authoritarianism — and you want to do something about it. Wahoo! You’ve taken the first and most difficult step: committing to action.

Now come the fun parts.

I want to be really clear on a couple things to start out. First, there is no one-size-fits-all best way to exercise your First Amendment rights of speech and association. Every successful social movement has employed a wide variety of tactics and repeatedly adjusted to respond to facts on the ground. Opt for action over agonizing about optimal tactics.

Second, be realistic. We are all busy. Reflect on the commitments you can actually sustain with room to grow. It is far better to regularly move the ball forward on a smaller effort than to dive into and never complete an ambitious one.

Third, be unique! You have unique talents, skills, and passions. Let those guide your advocacy. Focus on projects that bring you joy, things you actually look forward to engaging with week after week. Lean into the comparative skills and expertise you bring to the movement.

With all that in mind, here’s a short list of six ways everyone can protect democracy — even (especially) if going to a protest or some other more public form of engagement isn’t for you.


1. Check in with your local library

Local libraries are the backbone of an informed democratic citizenry, and they provide crucial resources for underserved communities. But their funding is under attack by the administration, which has cut critical funds nationwide.

So, give the library in your neighborhood a call. See how they are doing in relation to funding cuts and if there are ways you can support them. Do they take book donations? Need volunteers? See if there are teach-in or reading groups you can join — or even lead. Offer to help curate pro-democracy reading lists for various ages. Many libraries are open to suggestions for books to add to the collection — here are some recommendations from our team.

2. Fill the gaps left by government programs

Taking care of one another is essential movement building. Check in on your food pantry and community kitchen — many of which have faced funding cuts — to see how you can help. (snip-MORE at the page linked above: “Read on Substack”)

Smart Robot Vacs Don’t Look As Attractive To Me,

Manufacturer issues remote kill command to disable smart vacuum after engineer blocks it from collecting data — user revives it with custom hardware and Python scripts to run offline

News By Jowi Morales published 15 hours ago

The smart vacuum cleaner was remotely bricked for not collecting data.

An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device. That’s when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn’t consented to. The user, Harishankar, decided to block the telemetry servers’ IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after. After a lengthy investigation, he discovered that a remote kill command had been issued to his device.

He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again. After several rounds of back-and-forth, the service center probably got tired and just stopped accepting it, saying it was out of warranty. Because of this, he decided to disassemble the thing to determine what killed it and to see if he could get it working again.

Since the A11 was a smart device, it had an AllWinner A33 SoC with a TinaLinux operating system, plus a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware.

From this, he looked at its software and operating system, and that’s where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data. First of all, it’s Android Debug Bridge, which gives him full root access to the vacuum, wasn’t protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home.

This isn’t unusual, by far. After all, it’s a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer’s server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers. Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

So, why did the A11 work at the service center but refuse to run in his home? The technicians would reset the firmware on the smart vacuum, thus removing the kill code, and then connect it to an open network, making it run normally. But once it connected again to the network that had its telemetry servers blocked, it was bricked remotely because it couldn’t communicate with the manufacturer’s servers. Since he blocked the appliance’s data collection capabilities, its maker decided to just kill it altogether. “Someone—or something—had remotely issued a kill command,” says Harishankar. “Whether it was intentional punishment or automated enforcement of ‘compliance,’ the result was the same: a consumer device had turned on its owner.”

Unfortunately, many other smart vacuum brands use similar hardware, so it’s not far-fetched to think that they have the same setup. This is likely especially true for cheaper devices that have less capable hardware and aren’t capable of edge computing, meaning they’ll have to send the data to some faraway server for processing. But because your information is being offboarded to another device outside of your control, you really have no idea what’s happening to it, giving the manufacturer free rein to use it as it pleases.

In the end, the owner was able to run his vacuum fully locally without manufacturer control after all the tweaks he made. This helped him retake control of his data and make use of his $300 software-bricked smart device on his own terms. As for the rest of us who don’t have the technical knowledge and time to follow his accomplishments, his advice is to “Never use your primary WiFi network for IoT devices” and to “Treat them as strangers in your home.” (snip)
