The Sun Has Erupted Non-Stop All Month, and There Are More Giant Flares Coming

Over the past few weeks the sun “has undergone a series of giant eruptions that have sent plasma hurtling through space,” reports Science Alert:

Perhaps the most dramatic was a powerful coronal mass ejection and solar flare that erupted from the far side of the Sun on February 15 just before midnight. Based on the size, it’s possible that the eruption was in the most powerful category of which our Sun is capable: an X-class flare.

Because the flare and CME were directed away from Earth, we’re unlikely to see any of the effects associated with a geomagnetic storm, which occurs when material from the eruption slams into Earth’s atmosphere. These include interruptions to communications, power grid fluctuations, and auroras. But the escalating activity suggests that we may anticipate such storms in the imminent future. “This is only the second farside active region of this size since September 2017,” astronomer Junwei Zhao of Stanford University’s helioseismology group told SpaceWeather. “If this region remains huge as it rotates to the Earth-facing side of the Sun, it could give us some exciting flares.”

According to SpaceWeatherLive, which tracks solar activity, the Sun has erupted every day for the month of February, with some days featuring multiple flares. That includes three of the second-most powerful flare category, M-class flares: an M1.4 on February 12; an M1 on February 14; and an M1.3 on February 15. There were also five M-class flares in January. The mild geomagnetic storm that knocked 40 newly launched Starlink satellites from low-Earth orbit followed an M-class flare that took place on January 29.

The article suggests this is normal activity, since the sun is about halfway towards “solar maximum” (its peak of sunspot and flare activity) expected to arrive in 2025, while the “solar minimum” was in 2019.
Further Reading: SciTechDaily reports that the ESA/NASA Solar Orbiter spacecraft has now “captured the largest solar prominence eruption ever observed in a single image together with the full solar disc.”

Google to Overhaul Ad-Tracking on Android Phones Used by Billions

The Washington Post reports:

Google announced it will begin the process of getting rid of long-standing ad trackers on its Android operating system, upending how advertising and data-collection work on phones and tablets used by more than 2.5 billion people around the world.

Right now, Google assigns special IDs to each Android device, allowing advertisers to build profiles of what people do on their phones and serve them highly targeted ads. Google will begin testing alternatives to those IDs this year and eventually remove them completely, the company said in a Wednesday blog post. Google said the changes will improve privacy for Android users, limiting the massive amounts of data that app developers collect from people using the platform.

But the move also could give Google even more power over digital advertising, and is likely to deepen concerns regulators have already expressed about the company’s competitive practices… It made $61 billion in advertising revenue in the fourth quarter of 2021 alone….

The announcement comes over a year after Apple began blocking trackers on its own operating system, which runs on its iPhones, giving customers more tools to limit the data they share with app developers…. Google contrasted its plan with Apple’s, saying it would make the changes over the next two years, working closely with app developers and the advertising industry to craft new ways of targeting ads and measuring their effectiveness before making any drastic changes.
“We realize that other platforms have taken a different approach to ads privacy, bluntly restricting existing technologies used by developers and advertisers,” said Anthony Chavez, vice president of product management for Android security and privacy, in the blog post. “We believe that without first providing a privacy-preserving alternative path such approaches can be ineffective and lead to worse outcomes for user privacy and developer businesses.”
The Post also includes this quote from the chief security office of Mozilla (which began restricting ad tracking in Firefox several years ago). “Google’s two year plan is too long. People deserve better privacy now.”

Meta’s Social VR Platform Horizon Hits 300,000 Users

Since being rolled out to users in the U.S. and Canada, Meta’s social VR platform for the Quest headset, Horizon Worlds, has grown its monthly user base by a factor of 10x to 300,000 people. “Meta spokesperson Joe Osborne confirmed the stat and said it included users of Horizon Worlds and Horizon Venues, a separate app for attending live events in VR that uses the same avatars and basic mechanics,” reports The Verge. “The number doesn’t include Horizon Workrooms, a VR conferencing experience that relies on an invite system.” From the report: Before its December rollout, Horizon Worlds was in a private beta for creators to test its world-building tools. Similarly to how the gaming platform Roblox or Microsoft’s Minecraft works, Horizon Worlds lets people build custom environments to hang out and play games in as legless avatars. Meta announced this week that 10,000 separate worlds have been built in Horizon Worlds to date, and its private Facebook group for creators now numbers over 20,000 members.

Meta still hasn’t disclosed how many Quest headsets it has sold to date, which makes it hard to gauge Horizon’s success relative to the underlying hardware platform it runs on. But several third-party estimates peg sales at over 10 million for the Quest. Zuckerberg recently said that Meta would release a version of Horizon for mobile phones later this year to “bring early metaverse experiences to more surfaces beyond VR.”

“So while the deepest and most immersive experiences are going to be in virtual reality, you’re also going to be able to access the worlds from your Facebook or Instagram apps as well, and probably more over time,” the CEO said on Meta’s last earnings call. Bringing Horizon to mobile would position it as even more of a competitor to Rec Room, a well-funded, social gaming app with 37 million monthly users across gaming consoles, mobile phones, and VR.

Scientists Demonstrate Self-Awareness In Fish

Researchers from the Graduate School of Science, Osaka City University, have provided evidence to suggest that fish have the capacity for MSR, a behavioral test to determine whether an animal possesses the ability of visual self-recognition. As Phys.Org explains, an animal’s capacity for MSR is determined when they “touch or scrape a mark placed on their body in a location that can only be indirectly viewed in a mirror.” From the report: Professor [Masanori Kohda] says, “Previously, using a brown marking on the throat area of [cleaner fish Labroides dimidiatus], we had shown three out of four cleaner fish to scrape their throats several times after swimming in front of a mirror, a number on par with similar studies done on other animals like elephants, dolphins, and magpies.” However, one of the criticisms laid against this result was sample size and the need for repeated studies showing positive results. Teaming up with researchers from the Max Planck Institute of Animal Behavior in Germany and the University of Neuchatel in Switzerland, this study increased the sample size to 18 cleaner fish, with a 94% positive result of 17 of them demonstrating the same behavior from the previous study.
[…]
Prof. Kohda says, “Our previous study demonstrated MSR in L. dimidiatus; however, studies with other animals have shown that simply moving a mirror reignites aggressive behavior, suggesting the animal has only learned a spatial contingency, not MSR.” To address this, the team transferred mirror-trained cleaner fish to a tank with a mirror on one side of the tank and then three days later to a tank with a mirror on the other side, and saw the fish show no aggression toward their mirror image in both tanks. Also, to ensure the L. dimidiatus that passed the mark test truly are recognizing themselves, they placed mirror-trained fish in adjacent tanks that were separated by transparent glass. After two to three days, when fish largely reduced their aggressive behavior towards each other, they were marked the standard way the following night. None of the fish scraped their throat during the 120 mins of exposure to each other the following morning. This new experiment was recently published in PLOS Biology.

Physical Console Games Are Quickly Becoming a Relatively Niche Market

According to a new exclusive analysis of NPD Game Pulse data conducted by Ars Technica, the number of physical console game releases continues to decline even as the number of digital console games explodes. From the report: In terms of distinct game titles released in the United States, the raw number of new games available on physical media (i.e. discs or cartridges) declined from 321 in 2018 to just 226 in 2021, a nearly 30 percent decline (games released on multiple consoles are counted as a single title in this measure). The number of digital games released each year, on the other hand, remained relatively flat from 2018 through 2020. Then, in 2021, that number exploded to nearly 2,200 digital titles, a 64 percent increase from 2020. All told, the proportion of all new console games available exclusively as digital downloads increased from 75 percent in 2018 to nearly 90 percent in 2021.

These divergent trends suggest that the decline in new physical releases is not simply an artifact of consoles like the Xbox One and PS4 nearing the end of their lifecycles. Instead, as a whole, publishers seem to see a physical release as a less relevant market for an increasing proportion of titles. But the transition away from physical console games is not distributed evenly across all publishers. The largest publishers are much more likely to go through the hassle and expense of a physical release for their marquee titles. Among major publishers, a slight majority (56.4 percent) of distinct titles released in 2021 were available as physical releases. That’s still a major decline from 2018, though, when nearly 80 percent of titles from those publishers merited a physical launch. When those large publishers are filtered out, though, physical game releases quickly become a very minor part of the market. Just 8.1 percent of new games from those smaller companies were available on physical media in 2021, down in terms of both proportion and raw numbers from 2018.

The US Is Now Energy Independent

The U.S. produced more petroleum than it consumed in 2020, and the numbers were essentially in balance in 2021, according to the Energy Information Administration. Axios reports: The surge in oil prices taking place in 2022 has radically different implications for the U.S. economy — and for key geopolitical relationships in the Middle East and Russia — than in past episodes when energy prices have risen. In the past, when oil prices spiked, the impact on the U.S. economy was straightforward: It made America poorer, as more of our income went overseas to pay for imported energy. Now, after the shale gas revolution of the last 15 years, the impact is more subtle. Higher fuel prices disadvantage consumers and energy-intensive industries, yes. But there is a counteracting surge in incomes for domestic energy producers and their workers. Higher oil prices no longer depress overall measures of prosperity like GDP and national income, but rather shift it around toward certain regions. Texas and North Dakota win; Massachusetts and North Carolina lose.

As recently as 2010, America imported 9.4 million barrels a day of oil more than it exported. That had swung to a 650,000 barrel per day surplus in 2020, and preliminary numbers for 2021 show trade pretty much in balance last year. To the degree the U.S. does still import oil, more of it is coming from our closest ally. Canada was the source of 51% of U.S. petroleum imports in the first 10 months of 2021, compared with 8% from the Persian Gulf. By contrast, the Gulf states supplied more than 30% of American petroleum imports in 2008.

Otter Browser Aims To Bring Chromium To Decades-Old OS/2 Operating System

“The OS/2 community is getting close to obtaining a modern browser on their platform,” writes Slashdot reader martiniturbide. In an announcement article on Monday, president of the OS/2 Voice community, Roderick Klein, revealed that a public beta of the new Chromium-based Otter Browser will arrive “in the last week of February or the first week of March.” XDA Developers reports: OS/2 was the operating system developed jointly by IBM and Microsoft in the late 1980s and early 1990s, with the intended goal of replacing all DOS and Windows-based systems. However, Microsoft decided to focus on Windows after the immense popularity of Windows 3.0 and 3.1, leaving IBM to continue development on its own. IBM eventually stopped working on OS/2 in 2001, but two other companies licensed the operating system to continue where IBM left off — first eComStation, and more recently, ArcaOS.

BitWise Works GmbH and the Dutch OS/2 Voice foundation started work on Otter Browser in 2017, as it was becoming increasingly difficult to keep an updated version of Firefox available on OS/2 and ArcaOS. Firefox 49 ESR from 2016 is the latest version available, because that’s around the time Mozilla started rewriting significant parts of Firefox with Rust code, and there’s no Rust compiler for OS/2. Since then, the main focus has been porting Qt 5.0 to OS/2, which includes the QtWebEngine (based on Chromium). This effort also has the side effect of making more cross-platform ports possible in the future.
