Japan has recorded its hottest summer on record after a sweltering three months marked by thousands of instances of "extreme heat," with meteorologists warning that unseasonably high temperatures will continue through the autumn. From a report: The average temperature in June, July and August was 1.76C higher than the average recorded between 1991 and 2020, the Japan meteorological agency said, according to Kyodo news agency. It was the hottest summer since comparable records were first kept in 1898 and tied the record set in 2023, the agency said. Japan has recorded 8,821 instances of "extreme heat" -- a temperature of 35C or higher -- so far this year, easily beating the previous record of 6,692 set in 2023, it added. The brutal heat was not confined to Japan. Swathes of China logged the hottest August on record, the weather service said.

The hot weather prompted delays to the start of the new school year in some Chinese cities. State media reported on Tuesday that some schools and universities in Jiangxi, Chongqing, and Sichuan provinces had pushed the return to school out to 9 September, citing high temperatures. China Daily said Chongqing authorities had extended school holidays for all kindergarten, primary and secondary schools, and at least a dozen colleges and universities, "to ensure the safety and health of teachers and students amid the extreme heat."

Children under the age of two should not be exposed to any screens whatsoever and teenagers should have no more than three hours of screen time a day, according to guidelines announced by health authorities in Sweden. From a report: Parents and guardians should think about how they use screens with their children and tell them what they are doing on their phones when they use them in their presence, the advice says. The guidelines, announced on Monday, mark the first time that Folkhalsomyndigheten, Sweden's public health authority, has stipulated how parents should regulate screen time.

Screen use among two- to five-year-olds should be limited to a maximum of one hour, while children aged between six and 12 should not use screens for more than two hours. Among 13- to 18-year-olds, the limit is three hours. This is a sharp reduction on the current average screen time figures among Swedish children and young people, which is estimated to be four hours a day for nine- to 12-year-olds and more than seven hours a day -- not including schoolwork -- for 17- and 18-year-olds.

Elastic, creator of popular search engine Elasticsearch and visualization tool Kibana, plans to introduce the AGPL open-source license alongside its existing licenses. The move comes three years after Elastic ditched the Apache 2.0 license, sparking controversy in the tech community.

Founder Shay Banon says the change aims to clarify Elastic's market position following AWS's creation of OpenSearch, a fork of Elasticsearch. Despite initial friction, Banon claims Elastic's relationship with AWS has improved, citing growth in Elastic Cloud revenue and customer base.

schwit1 shares a report: If you are reading this and live in America, or used to live in America, or maybe just went to America one time many years ago, then you are almost certainly performing unpaid labor for the U.S. government and have been for years. How? By storing some of the billions of pennies the U.S. Mint makes every year that virtually no one uses.

Why are we still making tons (many thousands of tons) of pennies if no one uses them? That's a sensible question with a psychotic answer: We have to keep making all these pennies -- over $45 million worth last year -- because no one uses them. In fact, it could be very bad if we did.

When you insert a quarter into a soda machine, that quarter eventually finds its way back to a bank, from which it can be redistributed to a store's cash register and handed out as change -- maybe even to you, who can put it into a soda machine again and start the whole process over. That's beautiful. (Please be mindful of your soft drink consumption.)

But few of us ever spend pennies. We mostly just store them. The 1-cent coins are wherever you've left them: a glass jar, a winter purse, a RAV4 cup holder, a five-gallon water cooler dispenser, the couch. Many of them are simply on the ground. But take it from me, a former cashier: Cashiers don't have time to scrounge on the sidewalk every time they need to make change. That is where the Mint comes in. Every year it makes a few billion more pennies to replace the ones everyone is thoughtlessly, indefinitely storing and scatters them like kudzu seeds across the nation.

You -- a scientist of some kind, possibly -- might think an obvious solution now presents itself: Why not encourage people to use the pennies they have lying around instead of manufacturing new ones every year? We can't! Or, anyway, we'd better not. According to a Mint report, if even a modest share of our neglected pennies suddenly returned to circulation, the result would be a "logistically unmanageable" dilemma for Earth's wealthiest nation. As in, the penny tsunami could overwhelm government vaults.

That's not great, but at the end of the day we're talking only about pennies. How much could a penny cost to make? A penny? If only we lived in such a paradise. Unfortunately, one penny costs more than three pennies (3.07 cents at last count) to make and distribute! When I learned this, I lost my mind.

"Houston resident Brandy Deason put an Apple AirTag in her recycling to see where her plastic trash was going," writes Tom's Hardware.

"While many might expect the city would drop the recyclables off at a recycling center, Deason instead found her trash sitting in an open-air lot alongside millions of other pieces of trash at Wright Waste Management." Wright Waste Management did not allow CBS News to enter and inspect its premises. Still, the news team's drone camera discovered that all the trash picked up from the Houston Recycling Collaboration (HRC) was apparently just sitting there on its premises, stacked more than 10 feet high. This came as a shock, as the HRC was meant to revolutionize the city's recycling program, allowing it to process all kinds of plastic. Instead, we see all the collected waste sitting idle in open-air lots waiting for the right technology to appear.

That's because [Exxon-funded] Cyclix International, one of the partners in the HRC, has yet to open its massive factory to scale up its plastic recycling operation. The company said that it recycles all kinds of plastic and has even already set aside a sprawling space big enough to accommodate nine football fields. However, the current facility is just an empty husk without a single piece of machinery in sight.
Deason included 12 airtags in bags of recycling — and nine of them ended up at the HRC facility (with another one going to the local dump). In a video report, CBS News asked Deason what they thought about household recycling ended up in massive piles of plastic. "I thought it was kind of strange, because if you store plastic outside in the heat, it's a fire problem." In fact, that facility has already failed three fire-safety inspections by the county, according to CBS News. And while the facility has "applied" for approval to store plastic waste, that application has not yet been approved.

CBS asked a Cyclix project manager about the piles of unprocessed plastic sitting in the sun. "We need a huge supply of plastics to get ready for startup here," a spokesperson answered, "And we want to start that now in order to get ahead of it."

CBS's interviewer also raised another issue: the facility's plan is to recycle some of the plastic products into fuel. "So if you turn plastic waste into fuel that is then burned and creates greenhouse gas emissions, that's just another environmental problem."

Cyclix Project Manager: "Plastic waste is the challenge. So if we have the ability to take plastic waste and convert it to new products — that's what we're trying to do!"

CBS News points out that turning plastics into burn-able fuel is considered "recycling" by 25 states...

1.9 million solar panels began operating this year in California — at a Mortenson facility with 120,000 installed batteries that give it a storage capacity of 3,280 megawatts. An article in El Pais notes that this helped California pass 10,000 megawatts of photovoltaic storage in April — enough to meet 20% of demand — for the first time ever. (In 2019, the state had just 770 megawatts of storage capacity.)

Mark Rothleder, the vice president of the independent grid operator, California ISO (CAISO), said earlier this year that they will add another 1,134 megawatts in the first eight months of 2024. This is growth on top of the leap made last year. "In 2023 alone, the ISO successfully onboarded 5,660 megawatts of new power to the grid," Rothleder said at a conference in San Diego...

Renewable production was enough to supply the grid on 40 out of 48 days this spring, compared to seven days in the whole of last year. Lithium batteries appear to be undercutting the use of fossil fuels. Gas accounts for 40% of California's grid. However, its use in April registered its lowest proportion in seven years. "The data clearly shows that batteries are displacing natural gas when solar generation is ramping up and down each day in CAISO," notes an analysis by Grid Status, a firm specializing in energy issues. Natural gas was king on the grid in April 2021, 2022 and 2023. CAISO was sending between 9,000 and 10,000 megawatts produced from gas to the grid once solar ran out. Last April, however, it amounted to only 5,000 megawatts... [California's goal: run on 100% renewable energy by 2045.]

Arizona and Georgia have followed California's lead. But it is Texas, the other major U.S. giant in this industry, that is snapping at its heels. At the end of April, batteries supplied 4% of the grid's electricity, enough to power several million homes. Batteries are beginning to look like an alternative to a system heavily dependent on gas and coal.

Politico reports U.S. states have no uniform way of policing the use of overseas subcontractors in election technology, "let alone to understand which individual software components make up a piece of code."

For example, to replace New Hampshire's old voter registration database, state election officials "turned to one of the best — and only — choices on the market," Politico: "a small, Connecticut-based IT firm that was just getting into election software." But last fall, as the new company, WSD Digital, raced to complete the project, New Hampshire officials made an unsettling discovery: The firm had offshored part of the work. That meant unknown coders outside the U.S. had access to the software that would determine which New Hampshirites would be welcome at the polls this November.

The revelation prompted the state to take a precaution that is rare among election officials: It hired a forensic firm to scour the technology for signs that hackers had hidden malware deep inside the coding supply chain. The probe unearthed some unwelcome surprises: software misconfigured to connect to servers in Russia ["probably by accident," they write later] and the use of open-source code — which is freely available online — overseen by a Russian computer engineer convicted of manslaughter, according to a person familiar with the examination and granted anonymity because they were not authorized to speak about it... New Hampshire officials say the scan revealed another issue: A programmer had hard-coded the Ukrainian national anthem into the database, in an apparent gesture of solidarity with Kyiv.

None of the findings amounted to evidence of wrongdoing, the officials said, and the company resolved the issues before the new database came into use ahead of the presidential vote this spring. This was "a disaster averted," said the person familiar with the probe, citing the risk that hackers could have exploited the first two issues to surreptitiously edit the state's voter rolls, or use them and the presence of the Ukrainian national anthem to stoke election conspiracies. [Though WSD only maintains one other state's voter registration database — Vermont] the supply-chain scare in New Hampshire — which has not been reported before — underscores a broader vulnerability in the U.S. election system, POLITICO found during a six-month-long investigation: There is little oversight of the supply chain that produces crucial election software, leaving financially strapped state and county offices to do the best they can with scant resources and expertise.

The technology vendors who build software used on Election Day face razor-thin profit margins in a market that is unforgiving commercially and toxic politically. That provides little room for needed investments in security, POLITICO found. It also leaves states with minimal leverage over underperforming vendors, who provide them with everything from software to check in Americans at their polling stations to voting machines and election night reporting systems. Many states lack a uniform or rigorous system to verify what goes into software used on Election Day and whether it is secure.
The article also points out that many state and federal election officials "insist there has been significant progress" since 2016, with more regular state-federal communication. "The Cybersecurity and Infrastructure Security Agency, now the lead federal agency on election security, didn't even exist back then.

"Perhaps most importantly, more than 95% of U.S. voters now vote by hand or on machines that leave some type of paper trail, which officials can audit after Election Day."

To make America the "crypto capital of the planet," former U.S. President Donald Trump promised crypto-friendly policies, writes Politico, which "could have a new beneficiary: his own family." Trump has vowed to enact an array of pro-crypto policies in a bid to win votes — and campaign cash — from digital asset enthusiasts in recent months. Now, he's weaving the overtures into his pitch for his sons' forthcoming startup... It remains unclear what the Trump sons' crypto venture will look like. They have been teasing their plans to launch it for weeks, in part by positioning it as an alternative to the use of big banks.... ["Be defiant," reads the tagline on their World Liberty Financial home page — with nothing more than its name and the words "Coming soon."]

Trump's sons took over control of their father's business, the Trump Organization, after he became president in 2017, but he retained ownership of the company... It is unclear whether the crypto startup would be launched as part of the Trump Organization or as a separate entity. Either way, ethics experts and watchdogs say the crypto business could create the appearance of a conflict of interest if Trump wins back the White House this fall... From an "optics perspective, it's terrible," said Richard Painter, who served as chief White House ethics lawyer under former President George W. Bush and later ran for Congress as a Democrat. But he said it wouldn't violate any ethics laws.

The family venture is the latest way Trump has embraced the digital asset industry, which is pouring more than $160 million into the 2024 elections as it seeks to help elect allies up and down the ballot. Trump has also marketed his own line of non-fungible tokens, or NFTs, which are digital images of the former president that fans can purchase for $99... Trump's NFT sales could also raise ethics concerns, said Jordan Libowitz, vice president for communications at the Citizens for Responsibility and Ethics in Washington....

"[P]rior conflicts and illegalities took advantage of preexisting loopholes," said Norman Eisen, an ethics lawyer who served in the Obama White House and later helped build the first impeachment case against Trump. "Here, Trump appears to be promising to create the loopholes while his family is simultaneously designing a business venture to exploit them."
The article notes that Trump promoted his son's crypto venture on X this week with audio from Trump's speech at a crypto conference in July. "He first revealed his pro-crypto leanings — after previously deriding digital currency — at a Mar-a-Lago event in May with supporters who bought his crypto-linked digital trading cards..."

"Trump is also facing new questions about what he would do with his stake in the parent company of the social media service Truth Social," the article adds. (Although this week the stock hit a new low. After losing 50% of its value in six weeks, it's dropped below $20 per share for the first time since it started publicly trading...)

"Dirk Hohndel, a Linux kernel developer and long-time open source leader, wanted his audience at KubeCon + CloudNativeCon + Open Source Summit China 2024 Summit China to know he's not a Valkey developer," writes Steven J. Vaughan-Nichols. "He's a Valkey user and fan." [Hohndel] opened his speech by recalling how the open source, high-performance key/value datastore Valkey had been forked from Redis... Hohndel emphasized that "forks are good. Forks are one of the key things that open source licenses are for. So, if the maintainer starts doing things you don't like, you can fork the code under the same license and do better..." In this case, though, Redis had done a "bait-and-switch" with the Redis code, Hohndale argued. This was because they had made an all-too-common business failure: They hadn't realized that "open source is not a business model...."

While the licensing change is what prompted the fork, Hohndel sees leadership and technical reasons why the Valkey fork is likely to succeed. First, two-thirds of the formerly top Redis maintainers and developers have switched to Valkey. In addition, AWS, Google Cloud, and Oracle, under the Linux Foundation's auspices, all support Valkey. When both the technical and money people agree, good things can happen.

The other reason is that Valkey already looks like it will be the better technical choice. That's because the recently announced Valkey 8.0, which builds upon the last open source version of Redis, 7.2.4, introduces serious speed improvements and new features that Redis users have wanted for some time. As [AWS principal engineer Madelyn] Olson said at Open Source Summit North America earlier this year, "Redis really didn't want to break anything." Valkey wants to move a bit faster. How much faster? A lot. Valkey 8.0 overhauls Redis's single-threaded event loop threading model with a more sophisticated multithreaded approach to I/O operations. Hohndel reported that on his small Valkey-powered aircraft tracking system, "I see roughly a threefold improvement in performance, and I stream a lot of data, 60 million data points a day."
The article notes that Valkey is already being supported by major Linux distros including AlmaLinux, Fedora, and Alpine.

A climate newsletter from the Los Angeles Times asked the question: Is it ethical to have children in the face of climate change?

And they start by noting many people ask that question: A Pew Research Survey published in July found that among U.S. adults aged 18 to 49 who don't plan on having kids, more than a quarter — 26% — cited "concerns about the environment, including climate change," as a major factor. Of the people over 50 who did not have kids, 6% cited the same reason, pointing to a generational divide that may be fueled by growing awareness of the issue, as well as increasing exposure to worsening climate hazards...

I worry about the well-being of these kids: What kind of world will they live in? Will there be clean air and water? Will it be too hot or smoky to play outside? (To be blunt, the outlook on these matters doesn't look great under most emissions scenarios.) But the other side of the coin involves the well-being of the planet. Is it wrong to add more people at a moment when resources are so strained — when, say, the Colorado River is shrinking to record lows and the global average temperature is soaring to record highs? Each new child, after all, will bring not only a cute little footprint but a carbon footprint as well...

[T]he fact is that climate change is also affecting reproduction. Hotter temperatures and air pollution, for instance, have been linked to increased stillbirths, preterm births, lower birth weight and increased risk of hospitalization for newborns and infants, among other negative outcomes. Pregnant people are also especially vulnerable to climate hazards, which can trigger hypertension and other health issues and contribute to reduced fertility rates.
The newsletter makes many other points, but ultimately concludes that "children, after all, are one of the clearest symbols of how we, as a society, feel about the future." And it includes this quote from the book The Quickening, in which author Elizabeth Rush visits the melting Thwaites Glacier in Antarctic.

"I can celebrate the idea that to have a child means having faith that the world will change, and more importantly, committing to being a part of the change yourself."

Scientists have finally detected and measured the ambipolar field, a weak electric field surrounding Earth that was first theorized over 60 years ago. "Any planet with an atmosphere should have an ambipolar field," says astronomer Glyn Collinson of NASA's Goddard Space Flight Center. "Now that we've finally measured it, we can begin learning how it's shaped our planet as well as others over time." ScienceAlert reports: Here's how the ambipolar field was expected to work. Starting at an altitude of around 250 kilometers (155 miles), in a layer of the atmosphere called the ionosphere, extreme ultraviolet and solar radiation ionizes atmospheric atoms, breaking off negatively charged electrons and turning the atom into a positively charged ion. The lighter electrons will try to fly off into space, while the heavier ions will try to sink towards the ground. But the plasma environment will try to maintain charge neutrality, which results in the emergence of an electric field between the electrons and the ions to tether them together. This is called the ambipolar field because it works in both directions, with the ions supplying a downward pull and the electrons an upward one. The result is that the atmosphere is puffed up; the increased altitude allows some ions to escape into space, which is what we see in the polar wind.

This ambipolar field would be incredibly weak, which is why Collinson and his team designed instrumentation to detect it. The Endurance mission, carrying this experiment, was launched in May 2022, reaching an altitude of 768.03 kilometers (477.23 miles) before falling back to Earth with its precious, hard-won data. And it succeeded. It measured a change in electric potential of just 0.55 volts -- but that was all that was needed. "A half a volt is almost nothing -- it's only about as strong as a watch battery," Collinson says. "But that's just the right amount to explain the polar wind." That amount of charge is enough to tug on hydrogen ions with 10.6 times the strength of gravity, launching them into space at the supersonic speeds measured over Earth's poles. Oxygen ions, which are heavier than hydrogen ions, are also lofted higher, increasing the density of the ionosphere at high altitudes by 271 percent, compared to what its density would be without the ambipolar field. The findings have been published in the journal Nature.

An anonymous reader quotes a report from Electrek: The Biden administration has finalized a plan to expand solar on 31 million acres of federal lands in 11 western states. The proposed updated Western Solar Plan is a roadmap for Bureau of Land Management's (BLM) governance of solar energy proposals and projects on public lands. It bumps up the acreage from the 22 million acres it recommended in January, and this plan adds five additional states -- Idaho, Montana, Oregon, Washington, and Wyoming -- to the six states -- Arizona, California, Colorado, Nevada, New Mexico, and Utah -- analyzed in the original plan.

It would make the public lands available for potential solar development, putting solar farms closer to transmission lines or on previously disturbed lands and avoiding protected lands, sensitive cultural resources, and important wildlife habitats. [...] BLM surpassed its goal of permitting more than 25 gigawatts (GW) of clean energy projects on public lands earlier in 2024. It's permitted 29 GW of projects on public lands -- enough to power over 12 million homes. The Biden administration set the goal to achieve 100% clean electricity on the US grid by 2035.

For decades drugmakers have taken a more-is-more model when dosing cancer drugs in clinical trials. U.S. regulators want them to reconsider that approach. From a report: Companies with cancer drugs in clinical trials must strike a balance between doses high enough to thwart tumors, but low enough to avoid intolerable side effects. For years, Food and Drug Administration officials have expressed concern that cancer drug doses are often too high, leading to unnecessary side effects.

An FDA program launched in 2021, Project Optimus, requires companies to re-examine how they set doses of cancer treatments. This typically involves larger clinical trials to test doses to find those that optimally balance safety and efficacy. Entrepreneurs support the aim, but some fear the initiative will add time and cost to drug development, putting startups at a further disadvantage to larger competitors. [...] The FDA says it encourages drugmakers to discuss dosing plans with the agency and that new medications can still be brought to patients quickly.

U.S. Space Command chief Gen. Stephen Whiting called for greater transparency from China regarding space debris this week, citing concerns over the recent breakup of a Long March 6A rocket's upper stage. The incident, which occurred after an August 6 satellite launch, scattered over 300 pieces of debris in low-Earth orbit.

While acknowledging some improvement in U.S.-China military dialogue, Whiting stressed on the need for proactive communication about space junk, ArsTechnica reports. "I hope the next time there's a rocket like that, that leaves a lot of debris, that it's not our sensors that are the first to detect that, but we're getting communications to help us understand that," he said.

AnandTech, a pioneering technology news website, is shutting down after 27 years on August 30, 2024. Founded in 1997 by Anand Lal Shimpi, the site earned a reputation for its in-depth hardware reviews and technical analysis.

In a final post on the site, AnandTech Editor-in-Chief Ryan Smith cited changing market dynamics for written tech journalism as the primary reason for closure. The site's 21,500 articles will remain accessible indefinitely, hosted by publisher Future PLC. AnandTech's forums will continue operating under Future's management.

Lego plans to make half of its bricks from renewable or recycled materials by 2026, with a goal of fully transitioning by 2032. While the company cites higher production costs and challenges with existing materials, it says it's committed to not passing these costs onto consumers. The Guardian reports: The Danish company last year ditched efforts to make bricks entirely from recycled bottles because of cost and production issues. At the moment, 22% of the material in its colourful bricks is not made from fossil fuels. The toymaker hopes gradually to bring down the amount of oil-based plastic it uses by paying up to 70% more for certified renewable resin, the raw plastic used to manufacture the bricks, in an attempt to encourage manufacturers to increase production. [...] Lego has also expanded its brick takeback programme, Replay -- where consumers can donate old bricks to the company through free shipping -- into the UK and continued to test similar models in the US and Europe.

An anonymous reader shares a report: Every day for the last four years, dozens of people have shown up in the comments of one particular YouTube, declaring their love and appreciation for the content. The content: two minutes and six seconds of deep, low buzzing, the kind that makes your phone vibrate on the table, underscoring a vaguely trippy animation of swirled stained glass. It's not a good video. But it's not meant to be. The video is called "Sound To Remove Water From Phone Speaker ( GUARANTEED )." [...] If you believe the comments, about half the video's 45 million views come from people who bring their phone into the shower or bathtub and trust that they can play this video and everything will be fine.

The theory goes like this: all a speaker is really doing is pushing air around, and if you can get it to push enough air, with enough force, you might be able to push droplets of liquid out from where they came. "The lowest tone that that speaker can reproduce, at the loudest level that it can play," says Eric Freeman, a senior director of research at Bose. "That will create the most air motion, which will push on the water that's trapped inside the phone." Generally, the bigger the speaker, the louder and lower it can go. Phone speakers tend to be tiny. "So those YouTube videos," Freeman says, "it's not, like, really deep bass. But it's in the low range of where a phone is able to make sound."

The best real-world example of how this can work is probably the Apple Watch, which has a dedicated feature for ejecting water after you've gotten it wet. When I first reached out to iFixit to ask about my water-expulsion mystery, Carsten Frauenheim, a repairability engineer at the company, said the Watch works on the same theory as the videos. "It's just a specific oscillating tone that pushes the water out of the speaker grilles," he said. "Not sure how effective the third-party versions are for phones since they're probably not ideally tuned? We could test."

Scientists are harvesting genetic data from microorganisms in a North Yorkshire quarry, fueling a global debate over ownership and profit-sharing of natural genetic resources. Researchers from London-based startup Basecamp Research are collecting samples and digitizing genetic codes for sale to AI companies. This practice of trading digital sequencing information (DSI) has become central to biotechnology research and development. The issue will be a focal point at October's COP16 biodiversity summit in Cali, Colombia, The Guardian reports.

Developing nations, home to much of the world's biodiversity, are pushing for a global system requiring companies to pay for genetic data use. Past discoveries underscore the potential value: heat-resistant bacteria crucial for COVID-19 testing and marine organisms used in cancer treatments have generated significant profits. Critics accuse companies of "biopiracy" for commercializing genetic information without compensating source countries. Proposed solutions include a global fund for equitable benefit-sharing, though implementation details remain contentious.

Apple has laid off about 100 employees in its services group (source may be paywalled; alternative source), primarily affecting roles associated with the Apple Books app and Apple Bookstore. The San Francisco Chronicle reports: The impacted employees at the Cupertino-based tech giant were informed of the cuts on Tuesday, Bloomberg reported (paywalled). The layoffs spanned various teams under Senior Vice President Eddy Cue. The job cuts include roles primarily associated with the Apple Books app and Apple Bookstore, with the company shifting its focus to other divisions. Additionally, other services teams, such as the one managing Apple News, also experienced layoffs.

While Apple has largely avoided mass layoffs even as other major tech companies have downsized, it did lay off 614 employees in Santa Clara earlier this year. Those cuts marked Apple's first significant job reductions since the onset of the COVID-19 pandemic and coincided with the cancellation of its decade-long electric car project.

A new study of broadband reliability finds a top-two finish that you might not expect from recent surveys of ISP customer satisfaction: Charter's Spectrum and Comcast's Xfinity, the two largest cable operators in the US. From a report: Opensignal's report, published Thursday, draws on software telemetry collected from April 1 through June 29 of downtime, consistency of service, and how well a provider meets basic thresholds for speed, latency, and other core performance metrics. Spectrum comes in first with a "Reliability Experience" score of 741 out of 1,000, followed by Xfinity with 710, Verizon with 625, AT&T with 546, and T-Mobile with 525. Opensignal chose those five companies to study because each passes more than a third of US homes.

But while Comcast and Charter employ the same basic cable architecture except for a few fiber-to-the-home pockets, Verizon and AT&T have mixed networks. That includes extensive and growing fiber service but also fixed 4G and 5G wireless from Verizon and hybrid-fiber broadband from AT&T, both of which lack fiber's speed and capacity advantages, plus obsolete DSL connectivity. T-Mobile's home connectivity, meanwhile, is almost exclusively fixed wireless.
