Apple has released new battery health features in iOS 11.3 beta 2, which was seeded to developers today. BGR reports what those battery health functions look like, and how to disable power management if you're using an older iPhone: The feature is contained within a new "Battery Health" menu, which is under the "Battery" tab on iOS 11.3. The page only really has two fields: Maximum Capacity, which shows what percentage of the original charge your battery can still hold; and Peak Performance Capacity, which tells you if your phone's performance is being throttled due to the battery. Right now, there are no options to change anything within the menu. Maximum Capacity should be at 100% for newer phones, and it should fall down to around 80% over the course of about two years of normal use. A Redditor on the iOSBeta forum uploaded a photo of his iPhone 7, which is sitting at 87% capacity. That device still shows peak performance.
On older devices with a worse battery, the phone will show that reduced Maximum Capacity, as well as detail any performance slowdowns due to the decreased battery capacity. On devices that have weaker batteries, the Peak Performance Capability will change to read "This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again." A small blue hyperlink then says "Disable," which lets you manually turn off your iPhone's performance management.Read Replies (0)

After nearly a decade of development, SpaceX's Falcon Heavy rocket has successfully launched from pad 39A at NASA's Kennedy Space Center in Florida today. After reaching orbit, the two side boosters simultaneously landed at Landing Zone One. We do not know the status of the central core of the rocket, which was destined to land on the "Of Course I Still Love You" drone ship roughly 8:19 minutes into the flight.
According to Space.com, the Falcon Heavy is the most powerful rocket to launch since NASA's Saturn V -- the iconic vessel that, with 7.5 million pounds of thrust, accomplished the definitive Apollo-era feat of putting astronauts on the moon. Elon Musk says that Falcon Heavy is "twice as powerful as any other booster operating today." As for the payload, it includes a Tesla Roadster electric car. "The Falcon Heavy will send the vehicle around the sun in an elliptical orbit that will extend farther than Mars' orbit," reports Space.com. UPDATE: SpaceX has confirmed The Verge's reporting that the middle core of SpaceX's Heavy Rocket missed the drone ship where it was supposed to land. "The center core was only able to relight one of the three engines necessary to land, and so it hit the water at 300 miles per hour," reports The Verge. "Two engines on the drone ship were taken out when it crashed, SpaceX CEO Elon Musk said in a press call after the rocket launch. It's a small hiccup in an otherwise successful first flight."Read Replies (0)

On Tuesday, the review embargo lifted for full reviews of Apple's new HomePod smart speaker. The Verge's Niley Patel shared his thoughts on Apple's new HomePod in video and written form. Patel found that while it offers best-in-class sound for the price, Siri is frustratingly limited and the voice controls only work with Apple Music. Furthermore, Siri can't tell different voices apart, therefore raising some privacy concerns as anyone can come up to the speaker and ask Siri to send and read text messages and other private information aloud. Here's an excerpt from the report: The HomePod, whether Apple likes it or not, is the company's answer to the wildly popular Amazon Echo and Google Home smart speakers. Apple is very insistent that the $349 HomePod has been in development for the past six years and that it's entirely focused on sound quality, but it's entering a market where Amazon is advertising Alexa as a lovable and well-known character during the Super Bowl instead of promoting its actual features. Our shared expectations about smart speakers are beginning to settle in, and outside of engineering labs and controlled listening tests, the HomePod has to measure up. And while it's true that the HomePod sounds incredible -- it sounds far better than any other speaker in its price range -- it also demands that you live entirely inside Apple's ecosystem in a way that even Apple's other products do not. The question is: is beautiful sound quality worth locking yourself even more tightly into a walled garden? As for technical specifications, the HomePod comes in at 6.8 inches high, 5.6 inches wide, and weights 5.5 pounds. It features a high-excursion woofer with custom amplifier, array of seven horn-loaded tweeters, each with its own custom amplifier, six-microphone array, internal low-frequency calibration microphone for automatic bass correction, direct and ambient audio beamforming, and transparent studio-level dynamic processing.Read Replies (0)

According to a new study by Uber and Stanford economists, male Uber drivers get paid 7 percent more than their female counterparts in the U.S. "That's surprising, because Uber's driver assignments and pay are gender-blind, meaning a driver's gender isn't considered when matching riders or assigning fares," reports Recode. "Rather, pay has to do with trip length, distance and whether it's happening during surge-price hours or not." From the report: There are more male drivers -- women make up 27 percent of Uber drivers in the U.S. -- and male drivers tend to work longer hours. However, on an hourly rate, women still make less, according to the data, which measured trips by 1.8 million drivers from 2015 to 2017. According to the study, discrimination on the customer side isn't the reason for the pay gap, either. So why are female Uber drivers paid less than men? The study points to three reasons that make the gap disappear:
When and where: The times and places female Uber drivers work seem to be less profitable. That could be fewer overnight shifts, shifts with shorter wait times or surge-price shifts than men.
Driver experience: Drivers who've been with Uber longer get paid more, on account of knowing which routes and times tend to pay more. In general, men work for Uber longer than women so they are more experienced. The attrition rate after six months is 77 percent for women and 65 percent for men.
Speed: Male Uber drivers conduct more trips per hour than women, meaning they're actually driving faster, according to the data. More trips mean more money. About 50 percent of the earnings gap is explained away by differences in driving speed.Read Replies (0)

The marbled crayfish looks much like any other freshwater crustacean. It has two claws, ten legs, and an attractive blue-brown marbled shell. Yet this six-inch creature, found in streams and lakes around the world, is far more sinister than you might expect. From a report: Its new scientific name gives a few clues: Procambarus virginalis. Every marbled crayfish, known as a marmorkreb in German, is female -- and they reproduce by cloning themselves. Frank Lyko, a biologist at the German Cancer Research Center, first heard about the marbled crayfish from a hobbyist aquarium owner, who picked up some "Texas crayfish" at a pet shop in 1995. They were strikingly large, and they laid enormous batches of eggs -- hundreds, in a single go. Soon, the New York Times reports, the hobbyist was beset with so many crayfish he was giving them away to his friends. And soon after that, marmorkrebs were showing up in pet stores upon Europe. There was something very strange about these crayfish. They were all female, and they all laid hundreds of eggs without mating. These eggs, in turn, hatched into hundreds more females -- with each one growing up fully able to reproduce by herself. In 2003, scientists sequenced their DNA and confirmed what many owners already believed to be the case: Each baby crayfish was a clone of its mother, and they were filling Europe's fishtanks at alarming speed. Just 25 years ago, the marbled crayfish did not exist at all. Now, they can be found in the wild by the millions in Germany, the Czech Republic, Hungary, Croatia, the Ukraine, Japan, and Madagascar.Read Replies (0)

Copyediting app Grammarly included a gaping security hole that left users of its browser extension open to more embarrassment than just misspelled words. From a report: The Grammarly browser extension for Chrome and Firefox contained a "high severity bug" that was leaking authentication tokens, according to a bug report by Tavis Ormandy, a security researcher with Google's Project Zero. This meant that any website a Grammarly user visited could access the user's "documents, history, logs, and all other data," according to Ormandy. Grammarly provides automated copyediting for virtually anything you type into a browser that has the extension enabled, from blogs to tweets to emails to your attorney. In other words, there is an unfathomable number of scenarios in which this kind of major vulnerability could result in disastrous real-world consequences. Grammarly has approximately 22 million users, according to Ormandy, and the company told Gizmodo in an email that it "has no evidence that any user information was compromised" by the security hole. "We're continuing to monitor actively for any unusual activity," a Grammarly spokesperson said.Read Replies (0)

We already knew that thawing Arctic permafrost would release powerful greenhouse gases. On Monday, scientists revealed it could also release massive amounts of mercury -- a potent neurotoxin and serious threat to human health. From a report: Permafrost, the Arctic's frozen soil, acts as a massive ice trap that keeps carbon stuck in the ground and out of the atmosphere -- where, if released as carbon dioxide, the greenhouse gas would drive global warming. But as humans warm the climate, they risk thawing that permafrost and releasing that carbon, with microbial organisms becoming more active and breaking down the ancient plant life that had previously been preserved in the frozen earth. That would further worsen global warming, further thawing the Arctic -- and so on. That cycle would be scary enough, but U.S. government scientists on Monday revealed that the permafrost also contains large volumes of mercury, a toxic element humans have already been pumping into the air by burning coal. There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost, the scientists wrote in a study published in the journal Geophysical Research Letters. For context, that's "twice as much mercury as the rest of all soils, the atmosphere, and ocean combined," they wrote.Read Replies (0)

A fascinating story of how Indian women have persevered through various roadblocks, including cultural, to actively contribute to the open source community. An excerpt from the story: As Vaishali Thakker, a 23-year old open source programmer looked over the hall filled with around 200 people, she didn't know how to react to what she had just heard. Thakker was one of the five women on the stage at PyCon India 2017, a conference on the use of the Python programming language, in New Delhi. The topic of the discussion was "Women in open source." As the women started discussing the open source projects they had been working on, the challenges and so on, someone from the audience got up and drew the attention of the gathering to the wi-fi hotspots in the hall. They were named "Shut the fk up" and "Feminism sucks." "It was right on our faces," remembers Thakker. For their part, the organisers were upset and even warned the audience. But the event had no code of conduct for anyone to really penalise or expel the culprits. "It's disheartening when you're talking about the problem, someone is actually giving a proof that it (gender bias) indeed is a problem. In a way, I found it funny, because how stupid can you be to give the proof that the problem actually exists," says Thakker. And how. It's just been three years in her coding career but she is familiar with the high wall that gender stereotyping puts up in the world of software scripting. More so in her chosen field of coding. Thakker is among a small -- but fast-growing -- set of women coders from India shaping the future of several open source platforms globally including the Linux kernel, the core software program behind the world's biggest eponymous open source software.Read Replies (0)

An anonymous reader quotes a report from The Guardian: The top-ranking Democrat on the Senate intelligence committee has warned that YouTube's powerful recommendation algorithm may be "optimizing for outrageous, salacious and often fraudulent content" or susceptible to "manipulation by bad actors, including foreign intelligence entities." Senator Mark Warner, of Virginia, made the stark warning after an investigation by the Guardian found that the Google-owned video platform was systematically promoting divisive and conspiratorial videos that were damaging to Hillary Clinton's campaign in the months leading up to the 2016 election.
"Companies like YouTube have immense power and influence in shaping the media and content that users see," Warner said. "I've been increasingly concerned that the recommendation engine algorithms behind platforms like YouTube are, at best, intrinsically flawed in optimizing for outrageous, salacious and often fraudulent content." He added: "At worst, they can be highly susceptible to gaming and manipulation by bad actors, including foreign intelligence entities." YouTube's algorithm determines which videos to promote in the "Up next" column beside the video player. The Guardian found that "the algorithm was six times more likely to recommend videos that was damaging to Clinton than Trump, and also tended to amplify wild conspiracy theories about the former secretary of state."Read Replies (0)
