In three weeks of fighting, Russia has lost at least 270 tanks, according to the open source weapons tracking site Oryx -- almost 10% of its estimated active force. From a report: Ukraine's defense is proving so effective, in fact, that many analysts are attributing the failure of Russia's offense not only to its commanders, or to its tanks, but to the very idea of the tank itself, as a front-line weapon platform that can gain ground. The emerging evidence of tanks' tactical weakness is "striking," as one expert put it, and it has opened up a debate about whether tanks might be on their way to joining chariots and mounted cavalry in the boneyard of military history.

Cheap, low-flying drones are striking tanks from above. Soldiers are using charred suburban landscape to ambush tanks with a new generation of fire-and-forget weapons that makes tank-killing unsettlingly simple, even in the hands of a volunteer. "An infantry that is determined to fight is now super-empowered by having things like a huge number of point-and-shoot disposable anti-tank rockets," Edward Luttwak, a military strategist who consults for governments around the world, told Insider. Tanks have ruled land warfare for more than 80 years. It's their job to punch through enemy positions so infantry can flood in and hold the newly gained ground. Tanks have long been susceptible to soldier-carried weapons like bazookas and recoilless rifles, as well as improvised explosives such as the anti-tank "sticky bombs" seen in the film "Saving Private Ryan."

But looking at the ineffectiveness of Russian tank attacks in Ukraine, one can see how technology -- particularly advances in high explosives and guided missiles -- is further tipping the odds to favor anti-tank defenders, to the point where tanks could arguably be rendered obsolete. One defense analyst who spoke with Insider compared the role of tanks to that of the Swiss pikemen, Renaissance-era fighters armed with pikes and halberd who once were an army's frontlines. This vanguard role, held then by foot soldiers and now by tanks, will likely shift to drones, robotic vehicles, and long-range strike systems. "Tanks are going to move, over time, into more of a mopping-up role," said Paul Scharre, a former US Army Ranger and a director of studies at the Center for a New American Security.

An anonymous reader shares a report: Last year, the Google TV app user interface was completely redesigned and transformed into a hub for browsing movies and shows from your favorite streaming apps all in one place. It now appears that more changes are coming to the platform as Google has announced that in May 2022, movies or TV shows will no longer be available in the Google Play store. Instead, the Google TV app will be the official home for buying, renting, and watching movies and shows on your Android device. Other apps, games, and books will continue to live on the store. On Google TV, the experience of using Google Play Movies & TV will still be the same and users will get access to the latest new releases, rentals, and deals. When taking a look at the new Google TV app, customers will see a Shop tab where they can find all the titles that the tech giant offers.

Amid increasing global regulations over app stores and their commission structures, Google today announced the launch of a pilot program designed to explore what it calls "user billing choice." From a report: The program will allow a small number of participating developers, starting with Spotify, to offer an additional third-party billing option next to Google Play's own billing system in their apps. While Google already offers a similar system in South Korea following the arrival of new legislation requiring it, this will be the first time it will test the system in global markets.

As the debut pilot partner, Spotify will introduce both their own billing system alongside Google Play's own when the pilot goes live. Google did not say which other developers it has lined up for future tests, but noted Spotify was a "natural first partner" on the effort given its reach as one of the "world's largest subscription developers with a global footprint" and its "integrations across a wide range of device form factors." Spotify, of course, has also been one of the larger developers to push for regulatory changes to app stores' existing billing systems, having testified before Congress on the matter, joined lobbying groups, and backed app store legislation, including the Open Markets Act, that would require companies like Apple and Google to permit alternatives to existing app stores.

Nvidia, one of the largest buyers of outsourced chip production, said it will explore using Intel as a possible manufacturer of its products, but said Intel's journey to becoming a foundry will be difficult. From a report: Nvidia Chief Executive Officer Jensen Huang said he wants to diversify his company's suppliers as much as possible and will consider working with Intel. Nvidia currently uses Taiwan Semiconductor Manufacturing Co and Samsung Electronics to build its products. "We're very open-minded to considering Intel," Huang said Wednesday in an online company event. "Foundry discussions take a long time. It's not just about desire. We're not buying milk here."

Microsoft announced on Wednesday that it will expand its cybersecurity skilling initiative to 23 additional countries. The campaign, which began last year in the U.S., is part of the company's push to help solve the cybersecurity industry's growing talent problem, while also helping diversify the industry. From a report: Like many industries within tech, cybersecurity is facing both a workforce shortage and a widening skills gap among workers. According to Kate Behncken, vice president and lead of Microsoft Philanthropies, by 2025 there will be 3.5 million cybersecurity jobs open globally. Microsoft originally launched the skilling campaign in the U.S. last fall, partnering with 135 community colleges to skill and recruit workers into the cybersecurity industry. By expanding skilling and training to 23 countries, Microsoft aims to get ahead of the demand. The countries, which include Australia, Brazil, Canada and India, were chosen due to their "elevated cyberthreat risk."

Australia's record-breaking wildfires of 2019 and 2020 blasted smoke so high that even the ozone layer in the stratosphere was damaged, a new analysis shows. Hmmmmmm shares a report: The Black Summer bushfires, which raged along Australia's east coast from November 2019 to January 2020, caused unprecedented destruction. The fires burned more than 70,000 square kilometres of bushland, destroyed more than 3000 homes, and killed more than 30 people and billions of animals. Smoke billowed all the way to South America and triggered distant ocean algal blooms. Now, Peter Bernath at Old Dominion University in Virginia and his colleagues have shown that the smoke also pushed its way up into the stratosphere and triggered chemical reactions that destroyed ozone. They analysed data from the Atmospheric Chemistry Experiment satellite, which monitors levels of 44 different molecules in the atmosphere. This revealed that stratospheric ozone declined by 13 per cent in the middle latitude area of the southern hemisphere -- which includes Australia -- in the aftermath of the Black Summer fires.

Microsoft has announced an update to its translation services that, thanks to new machine learning techniques, promises significantly improved translations between a large number of language pairs. TechCrunch reports: Based on its Project Z-Code, which uses a "spare Mixture of Experts" approach, these new models now often score between 3% and 15% better than the company's previous models during blind evaluations. Z-Code is part of Microsoft's wider XYZ-Code initiative that looks at combining models for text, vision and audio across multiple languages to create more powerful and helpful AI systems.

"Mixture of Experts" isn't a completely new technique, but it's especially useful in the context of translation. At its core, the system basically breaks down tasks into multiple subtasks and then delegates them to smaller, more specialized models called "experts." The model then decides which task to delegate to which expert, based on its own predictions. Greatly simplified, you can think of it as a model that includes multiple more specialized models.

The U.S. Supreme Court's decision this month in FBI v. Fazaga, a case challenging FBI surveillance, will make it significantly harder for people to pursue surveillance cases, and for U.S. and European Union (EU) negotiators to secure a lasting agreement for transatlantic transfers of private data. The Hill reports: The justices gave the U.S. government more latitude to invoke "state secrets" in spying cases. But ironically, that victory undercuts the Biden administration's efforts to show that the United States has sufficiently strong privacy protections to sustain a new Privacy Shield agreement -- unless Congress steps in now. In July 2020, the EU Court of Justice (CJEU) struck down the EU-U.S. Privacy Shield, a legal framework used by thousands of U.S. companies to facilitate data transfers, because the U.S. failed to provide adequate protection for data belonging to people from the EU. Specifically, the court found that U.S. surveillance authorities, including Section 702 of the Foreign Intelligence Surveillance Act (FISA) and Executive Order 12333, permit unjustifiably broad government surveillance. The court also found that the Privacy Shield failed to provide adequate redress mechanisms for Europeans whose data is transferred to the U.S. -- namely, the ability to be heard by an independent court that can order binding remedies. In striking down Privacy Shield, the CJEU was clear: no EU-U.S. data-transfer agreement will survive the court's scrutiny until the U.S. narrows the scope of its surveillance and ensures that individuals subject to potentially illegal surveillance have a real, meaningful way to pursue accountability.

New submitter hawk writes: Government agencies would no longer be able to indefinitely conceal their secret seizure of email records under legislation introduced Tuesday that takes aim at gag orders. The Government Surveillance Transparency Act, sponsored by a bipartisan group of lawmakers from both chambers, puts limitations on gag orders that seek to block tech companies from altering users whose data has been seized. It targets a practice brought into the spotlight after journalists from CNN, The New York Times and The Washington Post all had their records seized by the Department of Justice (DOJ). The bill requires law enforcement agencies to notify surveillance subjects that their email, location and web browsing data has been seized, aligning with current practices for phone records and bank data. While the legislation allows the government to continue getting secret warrants to obtain such data, it also places a six-month limit on gag orders that prevent companies from notifying their users of the seizure. "When the government obtains someone's emails or other digital information, users have a right to know," Sen. Ron Wyden (D-Ore.) said in a release.

YouTube is the latest company to offer free shows TV with ads. The video giant says you'll now be able to stream nearly 4,000 episodes of TV for free, as long as you're also willing to watch ads during the show. From a report: Shows available include Hell's Kitchen, Andromeda, and Heartland, and you'll be able to watch them in the US on the web, mobile devices, and "most connected TVs via the YouTube TV app," YouTube says in a blog post. With the new free TV shows, YouTube is taking on a number of major competitors. One is over-the-air television -- by offering free TV on demand, YouTube is likely hoping that you'll see what's available on its platform instead of channel surfing to see what else might be on. And there are already many options for streaming ad-supported TV for free, including Tubi, Xumo, Plex, Roku, and offerings from Vizio, and Samsung -- just to name a few -- so YouTube is late to the game.

Abnormally hot air has hit both of the world's poles at once, while the extent of Arctic sea ice appears to have been historically low this winter. From a report: Temperature records were broken in Antarctica as warm air swept unusually far into the heart of the continent. Concordia station, which is high above sea level and has an annual average temperature of -50C, reached an all-time high of -12.2C on 18 March, beating the -13.7C record set in December 2016. Another research station, Vostok, also saw record high temperatures. "The Antarctic [heat] is really extreme. I haven't seen anything like that. Colleagues haven't seen anything this extreme," says Walt Meier at the US National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. A band of westerly winds around Antarctica usually isolates the continent from other weather systems. But in the past week, an "atmospheric river" of hot air, originating in the mid-latitudes, travelled down from Tasmania and South Australia, breaching those winds to travel far across the ice, says John Turner at the British Antarctic Survey.

Although such events aren't unprecedented, the temperatures this time are very high. Turner says while it is undoubtedly an "extreme event," he thinks the Antarctic heat looks like natural variability rather than climate change. Past research by Turner has found no discernible trend in extreme temperatures in Antarctica, where the hole in the ozone layer appears to have cancelled out the impact of global warming so far. The recent highs won't have any consequences such as impacts on landing strips for scientists stationed on the continent either, says Ted Scambos at the University of Colorado, Boulder, because most have already departed ahead of the Antarctic winter and those remaining are hunkered down with supplies. The record temperatures come shortly after Antarctic sea ice declined to a record low minimum extent, at 1.92 million square kilometres on 25 February. "It was quite a lot lower than anything else in the 40-plus year record," says Scambos.

Firefox is finally gaining proper AV1 support. Neowin reports: According to an update made to a post on Bugzilla, the Mozilla Foundation is finally ready to add hardware acceleration for the AV1 video format. Developers plan to implement improved AV1 support in the upcoming release of Firefox 100, scheduled to arrive on May 3, 2022. Hardware acceleration for AV1 video brings several noticeable benefits to customers. The standard developed by Alliance for Open Media and initially released in March 2018 offers better video compression than H.264 (about 50%) and VP9 (about 20%). Shifting AV1 video processing from software to hardware improves efficiency and reduces energy consumption, resulting in better battery life on tablets and laptops. Google and Microsoft announced hardware-accelerated AV1 video in Chrome and Edge in late 2020. Mozilla, on the other hand, did not rush to introduce improved AV1 support in Firefox. While it is easy to dunk on Firefox, there is a reason why developers took their time. Hardware-accelerated AV1 video is not something you can add to any computer with Windows 10, and it requires a PC with the most recent and powerful hardware.

An anonymous reader shares a report: A digital extortion gang with a murky background and unconventional methods -- one researcher called them "laughably bad" at times -- has claimed responsibility for a string of compromises against some of the world's largest technology companies. The group, known as Lapsus$, said in a series of public posts on the messaging app Telegram this week that it had accessed Okta, the San Francisco-based identity-management firm that provides authentication tools for an array of business clients. Okta said Tuesday that attackers may have viewed data from approximately 2.5% of its customers after breaching the laptop of an engineer at a third-party vendor.

Lapsus$ previously claimed to breach organizations including Nvidia, Samsung Electronics, and the gaming company Ubisoft Entertainment. The group said it also accessed data from Microsoft, saying it had gathered source code from the company's Bing search engine, Bing Maps and the Cortana digital assistant. Microsoft said attackers gained "limited access" to its systems, and that attackers had compromised a single account to gather data. In recent years, most hacking groups have used malware to encrypt a victim's files, then demanded payment to unlock them, so-called ransomware. Sometimes the groups steal sensitive data and threaten to make it public unless they are paid. Lapsus$ functions as a "large-scale social engineering and extortion campaign," though it does not deploy ransomware, Microsoft said. The group uses phone-based tactics to target personal email accounts at victim organizations and pays individual employees or business partners of an organization for illicit access, according to Microsoft. Lapsus$ also is known for hijacking individual accounts at cryptocurrency exchanges to drain user holdings.

Kenya's great lakes are flooding, in a devastating and long-ignored environmental disaster that is displacing hundreds of thousands of people. From a report: One of the first scientists to realise that something was wrong with the lakes was a geologist named Simon Onywere. He came to the topic by accident. Between 2010 and 2013 he had been studying Lake Baringo, Kenya's fourth-largest lake by volume. The bones of residents of the area around the lake weaken uncommonly fast, and Onywere was investigating whether this may be linked to high fluoride levels in the water. Then, in early 2013, while he was meeting with residents of Marigat, a town near the lake, one old man stood up. "Prof," he said. "We don't care about the fluoride. What we want to know is how the water has entered our schools."

Curious to know what the man was talking about, Onywere visited the local Salabani primary school. There, he found the lake lapping through the grounds of the school. Nonplussed, he took out his map. He looked at the location of the lake and the location of the school, and wondered how the lake had moved 2km without it becoming news. Onywere rushed back to Nairobi, where he and his colleagues at several Kenyan universities studied recent satellite images of the lake. The images showed that the lake had, in the past year, flooded the area around it. Then Onywere searched for images of some of the lakes nearby: Lakes Bogoria, Naivasha and Nakuru. All of these had flooded. As he extended his search, he saw that Lake Victoria, Africa's largest lake, had flooded, too. So had Lake Turkana, the largest desert lake in the world.

A new report has found that Facebook failed to detect blatant hate speech and calls to violence against Myanmar's Rohingya Muslim minority years after such behavior was found to have played a determining role in the genocide against them. From a report: The report shared exclusively with The Associated Press showed the rights group Global Witness submitted eight paid ads for approval to Facebook, each including different versions of hate speech against Rohingya. All eight ads were approved by Facebook to be published. The group pulled the ads before they were posted or paid for, but the results confirmed that despite its promises to do better, Facebook's leaky controls still fail to detect hate speech and calls for violence on its platform. The army conducted what it called a clearance campaign in western Myanmar's Rakhine state in 2017 after an attack by a Rohingya insurgent group. More than 700,000 Rohingya fled into neighboring Bangladesh and security forces were accused of mass rapes, killings and torching thousands of homes.

On Feb. 1 of last year, Myanmar's military forcibly took control of the country, jailing democratically elected government officials. Rohingya refugees have condemned the military takeover and said it makes them more afraid to return to Myanmar. Experts say such ads have continued to appear and that despite its promises to do better and assurances that it has taken its role in the genocide seriously, Facebook still fails even the simplest of tests -- ensuring that paid ads that run on its site do not contain hate speech calling for the killing of Rohingya Muslims.
