Now is a prime opportunity to buy a fitness watch for those cool-weather workouts. Amazon is running a one-day sale on Garmin smartwatches that knocks up to 52 percent off the price of the wearables. The sweetest deals may be in the middle of the pack, though. The athletics-oriented Forerunner 45 is down to an all-time low of $120 (40 percent off), while the general-purpose Vivoactive 4 is at its own record low of $190 (46 percent off).

The steepest discount is on the higher-end Forerunner 935 ($240, or 52 percent off), while deals also apply to the smaller Forerunner 45S and Venu Sq Music.

The Forerunner 45 remains a solid choice if you're just starting to take your fitness routine seriously. You can track your heart rate and detailed stats (such as max oxygen volume) for activities like running, yoga and beyond. The Vivoactive 4, meanwhile, steps things up with Pulse Ox tracking, local music playback from services like Spotify and even animated workout instructions you can follow on your wrist. Both are longevity champs with seven to eight days in regular smartwatch mode, and six to 14 hours of GPS-based use.

The caveats are more to do with the age of the designs and Garmin's focus. The Forerunner 45 and Vivoactive 4 are both from 2019, for example. They're still well-supported, but they won't pack the features of the company's latest models. There's also little doubt Garmin prioritizes fitness above general smartwatch features. You won't get a rich app ecosystem like you might with an Apple Watch or Wear OS device. Still, you probably won't object if you're more interested in optimizing your workouts than checking the weather — particularly at these prices.

Facebook whistleblower Frances Haugen's leaks suggest its problems with extremism are particularly dire in some areas. Documents Haugen provided to the New York Times, Wall Street Journal and other outlets suggest Facebook is aware it fostered severe misinformation and violence in India. The social network apparently didn't have nearly enough resources to deal with the spread of harmful material in the populous country, and didn't respond with enough action when tensions flared.

A case study from early 2021 indicated that much of the harmful content from groups like Rashtriya Swayamsevak Sangh and Bajrang Dal wasn't flagged on Facebook or WhatsApp due to the lack of technical know-how needed to spot content written in Bengali and Hindi. At the same time, Facebook reportedly declined to mark the RSS for removal due to "political sensitivities," and Bajrang Dal (linked to Prime Minister Modi's party) hadn't been touched despite an internal Facebook call to take down its material. The company had a white list for politicians exempt from fact-checking.

Facebook was struggling to fight hate speech as recently as five months ago, according to the leaked data. And like an earlier test in the US, the research showed just how quickly Facebook's recommendation engine suggested toxic content. A dummy account following Facebook's recommendations for three weeks was subjected to a "near constant barrage" of divisive nationalism, misinformation and violence.

As with earlier scoops, Facebook said the leaks didn't tell the whole story. Spokesman Andy Stone argued the data was incomplete and didn't account for third-party fact checkers used heavily outside the US. He added that Facebook had invested heavily in hate speech detection technology in languages like Bengali and Hindi, and that the company was continuing to improve that tech.

The social media firm followed this by posting a lengthier defense of its practices. It argued that it had an "industry-leading process" for reviewing and prioritizing countries with a high risk of violence every six months. It noted that teams considered long-term issues and history alongside current events and dependence on its apps. The company added it was engaging with local communities, improving technology and continuously "refining" policies.

The response didn't directly address some of the concerns, however. India is Facebook's largest individual market, with 340 million people using its services, but 87 percent of Facebook's misinformation budget is focused on the US. Even with third-party fact checkers at work, that suggests India isn't getting a proportionate amount of attention. Facebook also didn't follow up on worries it was tip-toeing around certain people and groups beyond a previous statement that it enforced its policies without consideration for position or association. In other words, it's not clear Facebook's problems with misinformation and violence will improve in the near future.

Saudi Arabia is making a commitment to reduce its impact on the environment, although the timeframe won't please critics. Reutersreports Crown Prince Mohammed bin Salman and energy minister Prince Abdulaziz bin Salman now expect Saudi Arabia to achieve net zero emissions by 2060. That's behind the 2050 target for the EU, United Arab Emirates, US and other countries.

The kingdom hoped to reach net zero through a circular carbon economy program while trying to bolster the "security and stability" of the world's oil markets. While the princes said Saudi Arabia would more than double CO2 emissions reductions by 2030, they maintained that the country needed time to "properly" conduct a transition.

The Crown Prince said there was a chance Saudi Arabia would hit its target before 2060, and state oil producer Saudi Aramco hopes to reach net zero by 2050. However, the country has been moving relatively slowly. It only opened its first renewable energy plant in April, and its first wind farm in August. It's still planning its first hydrogen fuel plant.

The conservative schedule isn't surprising. Although Saudi Arabia has been diversifying its economy, oil and gas represent about 50 percent of the country's gross domestic product and 70 percent of its exports. Aggressive emissions reductions could affect the kingdom's core business.

That dependence might also create problems, however. The UK and some US states are among those banning sales of new combustion engine passenger vehicles within the next 10 to 15 years, and others might not be far behind. Oil exporters like Saudi Arabia may have to adjust their emissions targets if electric vehicle sales grow quicker than expected.

Facebook is taking legal action in response to another large-scale data heist. According to The Record, the social network has sued Ukraine national Alexander Solonchenko for allegedly scraping data for more than 178 million users. Solonchenko reportedly exploited Messenger's contact import feature by using an automated tool that mimicked Android devices. He fed Facebook millions of phone numbers and gathered data whenever the site returned info on accounts with phone numbers.

The attacker supposedly conducted the campaign between January 2018 and September 2019 (when Facebook shut down the importer), and started selling it on a black market forum in December 2020. Facebook tracked Solonchenko down after he used his forum username and contact details for email and job boards. The man has also scraped data from other targets, Facebook said, including a major Ukranian bank.

In its complaint, Facebook asked for undefined damages as well as bans preventing Solonchenko from accessing Facebook or selling its scraped data.

This isn't the largest such incident. Hackers scraped data for 533 million users through the same feature. However, this illustrates Facebook's determination to crack down on data scraping — it's willing to pursue attackers in civil court in hopes of discouraging similar data raiding campaigns.

Eero will soon extend its mesh WiFi routers' smart home support to more universal formats. Company chief Nick Weaver told guests at a Verge event that all Eero routers with Thread support will receive an upgrade to the Matter smart home standard. Your 2017-era network could play nicely with smart devices from across the tech industry, to put it another way.

Weaver further hinted Eero was considering routers with cellular data backups, although he didn't commit to any plans. He wasn't worried about the rise of 5G home internet, noting that people were primarily moving to gigabit (wired) internet "in droves."

It wouldn't be a completely unexpected move when Amazon is upgrading most Echo speakers to support Matter. Eero is practically expected to follow along as an Amazon-owned company, and Ring has started building Eero routers into its alarm systems. Still, the update path may be particularly welcome if you were worried you might have to buy current-gen routers just to give Matter a try.

You'll have to wait a while longer for NASA's Artemis I mission. Space.comnotes NASA now expects to launch the uncrewed Artemis I flight test in February 2022, with the liftoff window opening as soon as February 12th. The Orion capsule has been stacked on top of the Space Launch System rocket, and blastoff is now mainly continent on testing.

That testing could take a while, however. The space agency plans tests for interfaces, engineering, communications and the countdown system. The most important test is effectively the "Wet Dress Rehearsal," when the Artemis I crew will try loading and unloading the propellants several weeks before launch. NASA won't set a firm launch date until after a successful rehearsal, so you won't get definitive timing for a long while.

Artemis I will send an Orion capsule with a sensor-equipped "moonikin" around the Moon (plus organ- and bone-like "phantoms") to study acceleration, radiation and vibration during the journey. Artemis II will carry a human crew. NASA hoped to land people on the Moon in 2024, although budgetary concerns and the fight over lander contracts have cast doubt on that target.

A successful Artemis I mission would nonetheless represent an important milestone. It would demonstrate the viability of both Orion and SLS. More importantly, humans would take one step closer to venturing beyond Earth's orbit for the first time in decades.

T-Mobile will wait a while longer to shut down Sprint's 3G network. The Vergereports T-Mobile has delayed the CDMA network shutdown from January 1st, 2022 to March 31st of that year. The carrier pinned the delay on "partners" who hadn't "followed through" on helping their customers transition to newer network technology.

This would supposedly give partners "every opportunity" to fulfill their obligations. "There should be no more room for excuses," T-Mobile said.

The explanation appears to be a not-so-subtle attempt to pin the blame on Dish. The satellite TV provider bought Boost Mobile from T-Mobile in July 2020 and planned to use Sprint's legacy network until it could move Boost customers to its 5G service. Dish argued this didn't give it enough time to migrate its customers, and accused T-Mobile of anti-competitive behavior meant to push Boost exiles to T-Mobile.

This may be a response to both Dish's original accusation and the ensuing fallout. The Justice Department told Dish and T-Mobile in July that it had serious concerns about the Sprint network shutdown, asking the two companies to do whatever was necessary to lessen the blow. The delay might address those worries and reduce the chances of more serious government scrutiny.

A delayed shutdown still isn't ideal. T-Mobile expects to shutter Sprint's LTE network on June 30th, 2022. This leaves a three-month window where Boost customers might have LTE access, but nothing else. While you'll probably have made a decision by the March cutoff if you're a customer, this won't be a very gradual shift for some users — they'll have just a short period of limited Boost service before they have to embrace 5G.

Rumors have persisted of a flagship Samsung tablet even larger than the Galaxy Tab S7+, and now you might know what it looks like. OnLeaks and 91Mobiles have shared what they claim are images of the Galaxy Tab S8 Ultra. The slate would minimize the impact of its huge 14.6-inch display by stuffing the front camera system into a notch — potentially distracting, but better than a conventional design that might be even larger.

The design wouldn't be quite so unusual on the other side. The leak suggests the Galaxy Tab S8 Ultra would have dual rear cameras and the familiar magnetic strip to hold your S Pen. The source claimed the imagery was "not 100 percent complete," so there's a chance the design could change slightly no matter how accurate it is as of this writing.

The regular Tab S8 and S8+ models aren't expected to use the notch. They might instead be subtle evolutions of the existing designs, which tuck the front camera into the bezel.

It's not clear just when the Galaxy Tab S8 Ultra would arrive. 91Mobiles speculates that Samsung might launch the design in November or December, but it would be odd to wait until the very end of the year to release an important tablet, even if chip shortages weren't a factor. It might be easier for Samsung to wait until early 2022, when it can launch the Tab S8 series alongside the Galaxy S22.

The redesigned MacBook Pro might be more powerful than you think, provided you have the right configuration. Apple has confirmed to Engadget and MacRumors that the 16-inch MacBook Pro with an M1 Max chip can invoke a previously hinted-at "High Power Mode." While the company was shy on details, macOS Monterey beta code suggested the mode would "optimize performance" for demanding tasks in return for the possibility of more fan noise.

This could be frustrating if you buy either the 14-inch MacBook Pro or a 16-inch system with the M1 Pro. This isn't surprising, though. Features like this by their nature drive up power consumption and heat, and Apple may want to make sure there's enough battery and thermal headroom (that is, a larger enclosure). The M1 Max is also a better fit for a mode like this than the M1 Pro — there's simply more performance to unlock.

If you do buy a higher-end MacBook Pro, though, this could be particularly helpful. Many pro users have moments when they need performance at all costs, such as a hurried video export or last-minute code compile. High Power Mode might help finish those tasks on time while putting a ceiling on noise in most situations.

American tech heavyweights are facing yet more scrutiny of their payment practices. The Consumer Financial Protection Bureau has ordered Amazon, Apple, Facebook, Google, PayPal and Square to hand over info concerning their payment system plans. The bureau wants to learn how these companies harvest data and control access to spot any anti-consumer behavior and provide "adequate" protections to the public.

The CFPB will also study Chinese tech firms' payment systems, including Alipay and WeChat Pay.

Director Rohit Chopra justified the order by warning that payments can pose a threat to the fair market thanks to their "tremendous scale and market power." He pointed to China as an example, noting that systems like Alipay and WeChat Pay are so thoroughly integrated with Chinese society that residents are effectively forced to use them as-is.

The bureau said it was following up on Federal Trade Commission oversight of Big Tech. The regulator has studied some of the companies' behavior in detail and, in the faces of Facebook and Google, put them under close watch. In 2020, for instance, the FTC investigated Facebook and Google acquisitions that hadn't been reported.

There's no certainty the CFPB orders will lead to regulatory action. However, they come right as politicians are trying to rein in Apple, Google and others for allegedly abusing app store payments. The Biden administration as a whole is also determined to crack down on tech companies. There's a chance CFPB will take corrective measures, even as those companies lower fees and otherwise try to make peace offerings.
