Tile will help you scan for unwanted tracking tags

Apple isn’t the only tracking tag company making it harder for stalkers and thieves to track you. Tile is rolling out a “Scan and Secure” feature in its Android and iOS apps to help you detect unwanted tags. Use it and the app will check if any suspicious Tile tags (or Tile-equipped devices) are traveling with you. The process can take up to 10 minutes, but you won’t need a Tile account or hardware.

If there are unwanted trackers, you’ll receive safety advice. Tile stressed that it will only identify the owners of misused tags through a “properly issued court order.” The company also made clear this was just a “first step” for improved safety, and that it would team up with advocacy groups and experts to refine its efforts.

Tag-based stalking has been possible for a while, but Apple’s AirTags underscored the problem — it’s all too easy for someone to slip a tracker into your coat or car and follow your movements without your knowledge or consent. Apple already has alerts for unwanted trackers, but it’s promising both earlier, more prominent alerts as well as a precision finding feature to help people remove unwanted tags. In that regard, Tile is simply following suit by upgrading its privacy measures.

Android 13 DP2 requires apps to ask permission for notifications

Google has released the second Developer Preview for Android 13, and it includes a big change in how the platform delivers alerts. Apps built for Android 13 will need to ask for permission before they can send notifications. Apps made for Android 12 or lower won’t face this obligation, but this could still be very helpful if you’re tired of having to disable notifications for apps that enable them by default.

Developers, meanwhile, can establish “downgradeable” permissions that scale back once they’re no longer required. An app that needed access to your location before might switch it off if a relevant feature was disabled, or if the permission is no longer necessary in Android 13.

After that, Developer Preview 2’s biggest upgrades mostly apply to audio. You’ll find Bluetooth LE Audio support that promises “high fidelity” sound without a big hit to battery life. Musicians will find MIDI 2.0 compatibility that lets you use higher-resolution and more expressive USB instruments. The newer Android 13 build is also better at handling non-Latin languages like Japanese and Tamil.

You’ll need a Pixel 4, Pixel 4a or newer Google phone to load the Android 13 DP2 system image outside of an emulator. As with past previews, you won’t want to install this on your main phone — there are likely to be plenty of remaining glitches and compatibility headaches. Google is still targeting platform stability between June and July, and the polished release isn’t due until sometime after that. If you can afford to experiment, though, it should be clear the new OS is quickly taking shape.

Apple will fix the Studio Display’s underperforming webcam

The Mac Studio may be a fine machine for some creative pros, but its companion Studio Display needs some polishing. An Apple spokesperson told TechCrunch and The Wall Street Journal the company will update the Studio Display through software to address an issue where the webcam isn’t “behaving as expected.” The company didn’t provide a timeline for the fix.

TechCrunch, The Journal and others have complained that the Studio Display webcam’s image quality is subpar, with grainy, washed-out video even in good lighting. Center Stage’s auto-framing helps mask the issue, but doesn’t eliminate it. The problem is odd given both the high quality of the 2021 MacBook Pro’s camera and the presence of an A13 chip meant partly to process webcam imagery — Apple has the knowledge and means to produce a fine-looking picture.

The performance mars what is otherwise a solid monitor with good (if unexceptional) visuals and relatively powerful speakers. It’s safe to say you’ll want to wait for the update if the Studio Display’s webcam will play a big role in your purchasing decision. If you’re going to spend $1,599 on a monitor, you want to know all its features are working as well as possible.

Black hole ‘quantum hair’ might solve a decades-old scientific paradox

Black holes have long been problematic for physicists — the general theory of relativity suggests information never comes out of them, but quantum mechanics wouldn’t allow that to happen. There might finally be an explanation that satisfies both camps, however. Researchers speaking to BBC News claim to have resolved the paradox with a theorem that black holes have “quantum hair,” or imprints in their gravitational fields left by components of the stars that formed them. This lets the information that went in also come out without violating either relativity or quantum mechanics.

The apparent solution came about after University of Sussex professor Xavier Calmet and others devised new mathematical techniques to approach the dilemma. It’s billed as the “yes hair theorem” in contrast to Prof. John Wheeler’s “no hair theorem” from the 1960s, which suggested that black holes were ‘bald’ entities that had no physical features beyond charge, mass and spin.

This new theorem doesn’t put a definitive end to debates. However, Calmet believes it might represent a key step in linking relativity to quantum mechanics and ending the conflict between the two theories. If so, it could prove highly valuable to both astrophysicists and the broader scientific community — they might not have to worry as much about theories breaking down in extreme situations.

Apple Watch Series 7 is back to an all-time low price of $339

Want an Apple Watch Series 7 now that spring is making outdoor exercise easier? Now might be a good time to get one. Amazon is once again selling the 41mm Series 7 in Midnight aluminum for $339, an all-time low price we haven’t seen since December. Other shades are also discounted to around $349. Blue, green and red 45mm aluminum models are down to a record-low $369 if a larger case looks better on your wrist.

Buy Apple Watch (41mm) at Amazon – $339Buy Apple Watch (45mm) at Amazon – $369

Apple Watch Series 7 remains a solid value half a year later. It’s a subtle evolution of Series 6, but the larger screen is easier to use and better for quick glimpses during a meeting or workout. A dustproof design might prove crucial during hikes. You might also appreciate the faster charging, particularly if you use sleep tracking and want a full battery before you start work. Add a strong app ecosystem and tight integration with Apple offerings like Fitness+ and it’s an easy choice if you’re an iPhone owner.

The usual caveats remain. Android users need not apply, for a start. The built-in sleep tracking is lackluster, and dedicated athletes may want a fitness watch. And while the battery life is stronger than before, you won’t find the days or weeks of use you get with some alternatives. Still, the Apple Watch is considered the gold standard of iPhone-friendly smartwatches for a reason — it’s a good all-rounder.

Congressional bills would ban tech mergers over $5 billion

Senator Elizabeth Warren has long made clear that she’s no fan of Big Tech, and her latest legislation proves it. She and House Representative Mondaire Jones have introduced legislation in their respective congressional chambers that would effectively ban large technology mergers. The Prohibiting Anticompetitive Mergers Act (PAMA) would make it illegal to pursue “prohibited mergers,” including those worth more than $5 billion or which provide market shares beyond 25 percent for employers and 33 percent for sellers.

The bills would also give antitrust regulators more power to halt and review mergers. They would have authority to reject mergers outright, without requiring court orders. They would likewise bar mergers from companies with track records of antitrust violations or other instances of “corporate crime” in the past decade. Officials would have to gauge the impact of these acquisition on labor forces, and wouldn’t be allowed to negotiate with the companies to secure “remedies” for clearing mergers.

Crucially, PAMA would formalize procedures for reviewing past mergers and breaking up “harmful deals” that allegedly hurt competition. The Federal Trade Commission has signalled a willingness to split up tech giants like Meta despite approving mergers years earlier. PAMA might make it easier to unwind those acquisitions and force brands like Instagram and WhatsApp to operate as separate businesses.

The act isn’t strictly focused on tech, but Warren made clear that industry was a target. She cautioned the FTC on Amazon’s proposed buyout of MGM Studios, and challenged Lockheed Martin’s since-abandoned attempt to buy Aerojet Rocketdyne.

If it becomes law, PAMA would ban the Amazon-MGM union (worth over $8.4 billion), Microsoft’s Activision deal ($68.7 billion) and relatively modest acquisitions like Google’s planned buyout of Mandiant ($5.4 billion). Tech firms would largely have to focus on acquiring ‘small’ companies, and would largely have to forego deals meant to expand market share or otherwise cement dominance in a given market.

However, there are obstacles that might prevent PAMA from reaching President Biden’s desk. Both the Senate and House bills have no Republican cosponsors — they’re either Democrats or left-leaning independents like Senator Bernie Sanders. That’s enough to clear the House, but the Senate bill could fail if it doesn’t obtain total support from sitting Democrats. As such, this may represent more of a declaration of Democrats’ intentions than a fundamental change in regulatory policies.

NASA’s James Webb Space Telescope passes key optics tests

Astronomers can breathe a little easier. NASA has confirmed the James Webb Space Telescope has passed checks and tests verifying its optical performance following a “fine phasing” alignment on March 11th. There also aren’t any critical problems or detectable blockages. Optical systems are performing “at, or above, expectations,” NASA said.

The fine phasing corrected alignment errors by using optical elements inside the James Webb Space Telescope’s NIRCam science instrument. The mission team gauged the performance by aligning and focusing the telescope on a star. The technology is very sensitive — as you can see above, Webb captured galaxies and stars in the background despite the very bright star in the middle.

NASA expects to finish aligning the observatory across all instruments by early May or sooner. After that, the team will spend two months prepping the instruments for capturing and sharing the first practical images and data in the summer.

The milestones show not just that Webb survived the 930,000-mile journey to its observation point, but that the telescope’s novel segmented mirror design works as promised — particularly important given the $10 billion price tag, numerous delays and Hubble’s mounting problems. For the most part, scientists can now concentrate on how they’ll use Webb to study the early universe and other elusive aspects of the cosmos.

Instacart lets you buy ingredients from TikTok recipes with a few taps

Ever see recipe on TikTok and wish you could quickly buy all the necessary ingredients online? You just might. Instacart has introduced “Shoppable Recipes” that help you snap up ingredients when you see a meal on TikTok and supporting websites. Tap a button and Instacart will both find the needed in-stock items as well as help you arrange delivery. You could spot a dinner idea in the afternoon and have everything you require by the evening without planning a trip to the grocery store.

Support for TikTok recipes is “gradually” rolling out to creators using the Jump feature. Web access will initially launch as part of a team-up with Hearst, which will provide shopping buttons on sites like Country Living and Good Housekeeping. More tie-ins will be announced later in the year, Instacart said.

The strategy isn’t subtle. Instacart is clearly hoping the added convenience will persuade you to choose its service over rivals like Uber. To some extent, this is also about extending the brand — the recipe buttons will serve as Instacart ads that might prove influential even if you aren’t keen on a given recipe.

Google Classroom will help teachers monitor progress with practice sets

Students using Google Classroom won’t have to wait until a test to know how well they understand a concept. Google has previewed an upcoming “practice sets” feature in Classroom that lets teachers gauge progress through automatically graded assignments. Pupils can see real-time feedback on their answers, and can ask for hints through explainers and videos. Teachers, meanwhile, will know which students are struggling with a given problem.

Google is currently testing Classroom practice sets with some schools, and plans a beta release sometime in the “coming months.” They’ll be available to both teachers using the Teaching and Learning Upgrade as well as schools using Google Workspace for Education Plus. The company is encouraging would-be early adopters to register their interest in joining the beta.

Classroom’s practice feature won’t always be useful. Not every exercise can fit into a web form, after all. When it is relevant, though, it could help teachers devote more attention to individual students or focus lesson time on concepts that stymie the class at large. Kids will ideally be well-prepared for tests, while educators can refine their courses.

You can now draft an email in Google Docs and send it to Gmail

Google might come to your rescue the next time you need to write a carefully-worded email. The company is rolling out a Google Docs update that lets Workspace and legacy G Suite users collaborate on Gmail drafts. Open the email draft template (Insert > Building Blocks > Email draft) and your colleagues can comment or make suggestions. You won’t always need to know recipients’ email addresses, either, as you can mention people by name.

When you’re ready to send the email, you just need to click a button to open a Gmail compose window and finalize the message. Docs will automatically populate all the relevant fields.

The feature will take up to 15 days to reach companies on Rapid Release domains, and will start reaching more cautious Scheduled Release customers on March 22nd. There’s no mention of availability for personal use. At work, however, this could prove very handy — lawyers could use it to produce an airtight email to a client, while marketers might work together on their ideal sales pitch.
