In 2005, the United States Congress laid out a clear mandate: To protect our civilization and perhaps our very species, by 2020, the nation should be able to detect, track, catalog, and characterize no less than 90 percent of all near-Earth objects at least 140 meters across.

As of today, four years after that deadline, we have identified less than half and characterized only a small percentage of those possible threats. Even if we did have a full census of all threatening space rocks, we do not have the capabilities to rapidly respond to an Earth-intersecting asteroid (despite the success of NASA’s Double-Asteroid Redirection Test (DART) mission).

Some day in the finite future, an object will pose a threat to us—it’s an inevitability of life in our Solar System. The good news is that it’s not too late to do something about it. But it will take some work.

Microsoft's web-based mobile game store opens in July

Engadget - Fri, 05/10/2024 - 04:00

In a couple of months, you'll be able to get Microsoft's mobile games from its own store. Xbox President Sarah Bond has revealed at the Bloomberg Technology Summit that the company is launching a web-based store where you can download its mobile games and get add-ons or in-app purchases at a discount. Bond said the company has decided to launch a browser-based store instead of an app to make it "accessible across all devices, all countries, no matter what" so that you don't get "locked to a single ecosystem."

Microsoft will only host its own games to start with, which means it will feature a lot of titles from Activision Blizzard. If you'll recall, it snapped up the gaming developer and publisher in a $70 billion deal that closed last year. You'll most likely find Candy Crush Saga, which has apparently generated $20 billion in revenue since it launched in 2012, and Call of Duty's mobile games in the first batch of titles available for download. Bond said that Minecraft may also be one of the first games you can get. 

An Xbox spokesperson told Bloomberg that this is "just the first step in [the company's] journey to building a trusted app store with its roots in gaming." Microsoft plans to open the app store to third-party publishers in the future, though it didn't share a timeline for that goal. 

The company first announced its intention to launch a gaming store for Android and iOS devices last year shortly before rules under the EU's Digital Markets Act became applicable. To comply with DMA rules, Apple and Google have to allow third-party app stores to be accessible on their platforms and to offer alternative billing systems for purchases. They're also compelled to allow app sideloading, which will be a massive change for Apple, a company known for its "walled garden" approach to business. 

Operators of third-party app stores will get to avoid some of the fees Google and Apple charge, but they'd still have to pay the companies for bypassing their mobile platforms' official stores. Both tech giants have already outlined how they're changing things up to comply with the DMA regulations. The companies' rivals found the changes they're making insufficient, however, prompting the European Commission to start investigating their compliance plans.

The best smart plugs in 2024

Engadget - Fri, 05/10/2024 - 04:00

Smart plugs aren’t the most complicated smart home devices — they really just turn stuff off and on — but they do make life a little easier. That’s what most people probably want from household automation anyway. In the past year or so of testing smart plugs, I’ve grown accustomed to having the living room lamps click on just before sunset and go off when I say goodnight to Alexa or the Google Assistant (Siri can turn off a few of my lights, but isn’t compatible with all of them). Most smart home device makers have a plug or two in their lineups, but finding one that’s compatible with your chosen ecosystem, easy to set up and reliably connects can involve a little trial and error. That’s why we tried more than a dozen models to find the best smart plugs you can buy right now.

What to consider when buying a smart plug

Before you buy one, it helps to know how a smart plug works best. They are designed for things that have an on/off switch, making them great for turning lamps into smart lights. If you want a plug-in fan to move some air around before you get home, a smart plug can help. You can load a basic coffee maker with grounds and water the night before and wake up to a fresh pot in the morning. And instead of an air purifier running all day, you could set it to just run when you’re away. But gadgets that needs to be programmed further, or requires a stand-by mode, isn’t ideal. If you want to control built-in lights, you’ll need smart switches, which are more involved than smart plugs as they can involve installation.

Some smart plugs can even monitor how much energy they use and display those figures within their companion app. That might not be much use on its own, as lamps with LED bulbs consume very little energy, but it could help you keep tabs on your overall energy consumption. 

Setup and use

Adding a smart plug to your home is relatively simple. You’ll use the manufacturer’s app to initially connect, after which you can add the plug to a compatible smart home ecosystem so you can use voice control and other features. Both the brand’s app and your smart home app will let you name the plug, set schedules and program “routines” which provide automation for multiple smart devices at once. But as you can guess, a manufacturer’s app only lets you control products from that brand. If you want whole-home automation, operating, say, a plug from TP-Link’s Kasa, a bulb from GE’s Cync and a camera from Arlo without switching apps, you’ll need to use a smart home platform, which means you’ll need to consider compatibility.

Compatibility

Smart home devices connect through wireless protocols, often using more than one to communicate with your phone, smart speaker, router and in some cases, one another. The majority of smart plugs use Wi-Fi, but some have recently incorporated Matter, a relatively new wireless standard intended to solve integration issues between different brands and manufacturers, while also improving security and reliability.

More of these smart plugs are coming to market and, for now, most Matter devices work via Wi-Fi, Bluetooth and a low-power mesh network called Thread. Matter requires a controller that stays at home, like a hub or smart speaker, to manage things when you’re out and about.

As for Bluetooth, most plugs, including all Matter plugs, use the short-range protocol to get the device set up for the first time. Some can continue to run on Bluetooth in the absence of another option, but the connection isn’t as reliable and you won’t be able to control the plug when you’re away from home, or perhaps even just on the other side of the apartment.

Because Matter is relatively new, it may be easier to consider the manufacturer’s system you’d use the most. There are four major “branded” smart home platforms: Amazon’s Alexa, Google Home, Apple’s HomeKit and Samsung’s SmartThings. The first two work with the widest range of brands and are compatible with both iOS and Android devices. HomeKit not only limits app access to Apple devices, but it’s also compatible with fewer plugs. You can also turn to open-source software like Home Assistant or go with the larger functionality of IFTTT if you want to, say, have your lights turn off when your Uber arrives. For the purposes of our testing, we stuck with the four big players. Nearly every plug we looked at clearly stated which platforms it works with, both on the packaging and retail product pages.

Of course, there’s no rule that says you have to stick with one home assistant. You might have an Echo Dot in the basement, a HomePod in the living room and a Google Nest Mini in the kitchen, each controlling any compatible devices. My kid has a great time telling Alexa to turn on a light then asking the Google Assistant to turn it back off.

All of our top picks recommended here don’t require a hub and connect directly to your home’s Wi-Fi router. That means if you already have wireless internet and a smartphone or tablet, you can quite literally plug and play. The exception is Apple’s HomeKit. If you want to pair up a compatible plug with that platform, you’ll need a HomePod speaker, Apple TV or an iPad that stays in your home to enable remote control when you’re away.

Some smart plugs require a hub regardless of which platform you use. For our guide, we focused on the simplicity (and lower cost) of options that work on their own, but hub-dependent devices may make sense in certain situations. Some companies, like Aqara for example, make a vast range of smart home products, adding automatic shades, window sensors, smart locks and air quality monitors to the more traditional cameras and plugs. If you’re going all-in on one brand and plan to get a plethora of connected devices, a hub can keep your Wi-Fi network from getting too crowded and provide a more seamless setup with reliable connectivity.

Sharing

Once a plug is set up with your platform and voice assistant of choice, anyone can control the plug just by talking. If someone else wants to control things with their phone, things get more complicated. Google makes it easiest, allowing you to invite another person just by tapping the + button within the Home app. Whomever you invite will have full access to your connected devices – including cameras – so this is only for people you trust the most.

HomeKit makes it similarly easy to grant app access to someone else, but as with most things Apple, it only works for other iOS users. Amazon only allows you to share access to your Echo, not your connected home devices.

Many smart plug manufacturers allow you to share control through their app by inviting another person via email. But this only grants access to devices of that brand. Hopefully as Matter expands, multi-admin features will become more widespread.

If you get a new Wi-Fi network

Most people will wirelessly connect their smart plugs to their home’s Wi-Fi router. Matter, Z-Wave, Thread and other smart home protocols can work over local networks, but for most setups, the signals telling your plugs what to do will be dispatched through your router. If you happen to get a new one (like I did when it became clear my very basic gateway could not handle the number of smart home devices being tested) you’ll need to take a few steps to get everything reconnected.

Depending on the brand, the steps may simply involve using the plug’s companion app to update your credentials (network name and password). Or it will require deleting the device in the companion app, doing a factory reset (typically by pressing the onboard button for 10 seconds) and setting up the plug like it's brand new. GE Sync and Emporia plugs allow for a credentials update via their apps, others, like TP-Link Kasa and Meross plugs require deletion and a factory reset to get along with your new network. Amazon’s smart plug updates automatically after updating the associated Echo device.

How we tested the best smart plugs

Before we decided which smart plugs to test, we considered brands Engadget staffers have had the best experiences with, both in review capacity and personally. We also checked out other online reviews. We then looked at factors like price, compatibility and relative popularity. I got ahold of ten indoor smart plugs and four outdoor versions from eight manufacturers.

I set up each one using its companion app, then added it to all compatible smart home platforms. Plugging in a cadre of lamps and string lights, I tested the plugs using an iPhone 11, Galaxy S10e, Echo Dot, HomePod mini and Nest Mini. I accessed the plugs via the apps and through voice commands and controlled them in my home and away from it. I programmed schedules and routines and moved the plugs to different outlets, including ones in the basement to gauge range. For the outdoor devices, I plugged them into an outlet in the garage (approximately 85 feet from my Wi-Fi router) and an outlet attached to the back of the house.

Here’s every smart plug tested before settling on our top picks:

*Emporia issued a recall on its smart plugs purchased before August 1, 2023 due to a potential fire risk, though no incidents were reported. The plugs have since been updated to resolve the issue and are back on sale. We’ll be testing the revised version for an upcoming update to this guide.  

The best outdoor smart plugs

Most people will likely use outdoor plugs for two things: patio lighting and holiday string lights. The devices are designed for the outdoors with ingress protection rating of IP64 or higher, which means they’re impervious to dust and can handle splashing water from rain and sprinklers. They have a longer Wi-Fi range than indoor plugs, for obvious reasons, and many have dual outlets, with individual control over each one.

Setup is the same as for indoor plugs: you’ll use your phone to help the plug find your Wi-Fi using its companion app. The only tricky part is getting your phone within Bluetooth range of the plug (which it uses to initialize setup) and in Wi-Fi range at the same time. I had to awkwardly stand at a triangulated point in the middle of my driveway to get things communicating properly. Once set up, the plugs will communicate using your router for voice and app control and your phone needn’t be anywhere near the plug.

Other smart plugs we tested Meross Matter plug (MSS115)

I wasn’t able to test the Meross Matter plug fully. It requires Wi-Fi splitting, a process that’s certainly possible for the average consumer, but more involved than it should be, considering the more than dozen other plugs I’ve tested don’t require such a step. The plug itself also blocked the other outlet. Meross has an updated version of the Matter device on the way, one that looks to solve both issues and we’ll update this guide accordingly once we’ve had a chance to test it.

Roku Smart Plug

Roku’s smart home gear is basically Wyze equipment with an app and packaging that are more purple. The Roku smart plug performed just fine with both compatible voice assistants (Alexa and Google Assistant). The companion app doesn’t offer scheduling that revolves around the timing of the sunset in your area, but the plugs go for less than $10 each and if you’ve got a Roku TV or streaming device set up and want to keep everything on-brand, it could be a fit.

Aquara Smart Plug

The Aqara plug requires an Aqara hub. In tests, the connectivity was solid and the companion app allowed for useful if/then automations that can rope in other Aqara devices like locks, window shades, cameras and more. The plug also worked well with voice assistants from Amazon, Google and Apple. As a stand-alone plug, however, it’s tough to recommend the nearly $100 combo to anyone who isn’t planning to get a complete Aqara smart home setup.

There is still some work to do to prepare Sierra Space's Dream Chaser spaceplane for its first mission, but the company says the winged resupply craft for the International Space Station will soon ship to its launch site in Florida.

The Dream Chaser will take off on top of a United Launch Alliance Vulcan rocket to head for the space station. A spokesperson for Sierra Space told Ars the spaceplane's launch is scheduled for the third or fourth quarter of this year.

But Sierra Space will transport the Dream Chaser to NASA's Kennedy Space Center in Florida with a to-do list. There are two more significant tests the spacecraft must complete at the launch site. Technicians must also finish work on Dream Chaser's heat shield before it is ready to go on top of its Vulcan launcher. It's unclear how long these activities will take to complete.

Jack Dorsey claims Bluesky is 'repeating all the mistakes' he made at Twitter

Engadget - Thu, 05/09/2024 - 18:43

Just in case there was any doubt about how Jack Dorsey really feels about Bluesky, the former Twitter CEO has offered new details on why he left the board and deleted his account on the service he helped kickstart. In a characteristically bizarre interview with Mike Solana of Founders Fund, Dorsey had plenty of criticism for Bluesky.

In the interview, Dorsey claimed that Bluesky was “literally repeating all the mistakes” he made while running Twitter. The entire conversation is long and a bit rambly, but Dorsey’s complaints seem to boil down to two issues:

  1. He never intended Bluesky to be an independent company with its own board and stock and other vestiges of a corporate entity (Bluesky spun out of Twitter as a public benefit corporation in 2022.) Instead, his plan was for Twitter to be the first client to take advantage of the open source protocol. Bluesky created.

  2. The fact that Blueksy has some form of content moderation and has occasionally banned users for things like using racial slurs in their usernames.

“People started seeing Bluesky as something to run to, away from Twitter,” Dorsey said. “It's the thing that's not Twitter, and therefore it's great. And Bluesky saw this exodus of people from Twitter show up, and it was a very, very common crowd. … But little by little, they started asking Jay and the team for moderation tools, and to kick people off. And unfortunately they followed through with it. That was the second moment I thought, uh, nope. This is literally repeating all the mistakes we made as a company.”

Dorsey also confirmed that he is financially backing Nostr, another decentralized Twitter-like service popular among some crypto enthusiasts and run by an anonymous founder. “I know it's early, and Nostr is weird and hard to use, but if you truly believe in censorship resistance and free speech, you have to use the technologies that actually enable that, and defend your rights,” Dorsey said.

A lot of this isn’t particularly surprising. If you’ve followed Dorsey’s public comments over the last couple years, he’s repeatedly said that Twitter’s “original sin” was being a company that would be beholden to advertisers and other corporate interests. It’s why he backed Elon Musk’s takeover of the company. (Not coincidentally, Dorsey still has about $1 billion of his personal wealth invested in the company now known as X.) He’s also been very clear that he made many of Twitter’s most consequential moderation decisions reluctantly.

Unsurprisingly, Dorsey’s comments weren’t well-received on Bluesky. In a lengthy thread, Bluesky’s protocol engineer Paul Frazee said that Twitter was supposed to to be the AT Protocol’s “first client” but that “Elon killed that straight dead” after he took over the company. “That entire company was frozen by the prolonged acquisition, and the agreement quickly ended when Elon took over,” Frazee said. “It was never going to happen. Also: unmoderated spaces are a ridiculous idea. We created a shared network for competing moderated spaces to exist. Even if somebody wanted to make an unmoderated ATProto app, I guess they could? Good luck with the app stores and regulators and users, I guess.”

While Dorsey was careful not to criticize Musk directly, he was slightly less enthusiastic than when he said that Musk would be the one to “extend the light of consciousness” by taking over Twitter. Dorsey noted that, while he used to fight government requests to take down accounts, Musk takes “the other path” and generally complies. “Elon will fight in the way he fights, and I appreciate that, but he could certainly be compromised,” Dorsey said.

Bluesky CEO Jay Graber, who was handpicked by Dorsey to lead Bluesky, also addressed Dorsey's comments, saying the Twitter founder doesn't "fully understand" the work the company is doing. "With all due respect to Jack for having the vision to invest in decentralized protocols, we’ve carried out the work in a way I don’t think he fully understands," she wrote. "Bluesky is structurally open in a way Twitter has never been, but the design of atproto allows it to feel familiar and easy to use."

Update May 10, 2024, 11:50 AM ET: This post has been updated with comments from Bluesky CEO Jay Graber.

Asahi Linux, the project that aims to bring desktop Linux to Apple hardware with Apple silicon—the M series of chips—is out with Fedora Asahi Remix 40. More hardware features of Apple devices are supported, the Fedora Linux 40-based distro ships with KDE's new Plasma 6 desktop, and untold numbers of bugs are squashed, to be replaced with reams more.

Fedora Asahi Remix is a "fully integrated distro," according to the Asahi team, and you can "expect a solid and high-quality experience without any unwanted surprises." It supports all the M1 and M2 devices in the MacBook, Mac Mini, Mac Studio, and iMac lines. It's OpenGL 4.6 and OpenGL ES 3.2 certified, and comes with "the best Linux laptop audio you've ever heard."

So, should you install it on your Mac? Keep scrolling down Asahi's release page and check the "Device support" section. Still missing from most M-series Apple devices are support for Thunderbolt and USB4, built-in microphones, and Touch ID, as well as USB-C display support. Speakers are not supported on the iMac. And HDMI audio is in rough shape, being able to "break audio on the system completely."

Apple apologizes for its tone-deaf ad that crushed human creativity to make an iPad

Engadget - Thu, 05/09/2024 - 16:11

Apple has reportedly apologized for its tone-deaf “Crush!” ad that sparked a furious backlash with artists, musicians and other creators. AdAge reports that Apple said the video “missed the mark” and has scrapped plans to run the cutesy-turned-cringey commercial on TV.

It’s clear that Apple intended for the ad to serve as a metaphor for all the myriad creative tools one has when they throw down $1,000 or more for a new iPad Pro. Run during Tuesday’s event, the video shows a series of musical instruments and other tools for human expression, including a guitar, drums, trumpet, amplifiers, record player, TV and much more. “All I Ever Need Is You” by Sonny & Cher soundtracks the clip.

Soon, it’s revealed that the objects are all sitting on an industrial crusher, which descends upon the scattered creative instruments, exploding in plumes of satisfyingly colorful smoke. But when the crusher pulls back up, we see that everything was transformed into a shiny new iPad Pro.

Apple

A decade ago, this ad likely wouldn’t have been a big deal. But Apple’s marketers completely whiffed on the context of the moment. The ad comes weeks before Apple will take the stage at WWDC to announce its generative AI features that its investors have been salivating for.

Generative AI, as you may have heard, needs something to train on — and that means humans’ work. It learns from existing content to make algorithmically generated words, pictures, music, voices or who knows what else. It also has the capability to put those same creators — most of whom don’t have cushy jobs at Apple or other Big Five tech companies — out of work as corporations and consumers eagerly adopt the robots destined to put creators on the unemployment line.

Context is everything, and Apple failed spectacularly there. Its ad serves as a pitch-perfect metaphor for generative AI’s potential to crush human creation, turning us all into “prompt artists” who type words into text boxes to replace their years of training and experience. (Granted, generative AI has genuinely exciting applications, too, but much more needs to be made of the society-level chaos it can and will unleash.)

“Creativity is in our DNA at Apple, and it’s incredibly important to us to design products that empower creatives all over the world,” Tor Myhren, Apple VP of marketing communications, told AdAge. “Our goal is to always celebrate the myriad of ways users express themselves and bring their ideas to life through iPad. We missed the mark with this video, and we’re sorry.”

Hey, an apology means something. But we’ll see what tone Apple adopts next month when it rolls out the tools that set the stage for the apology in the first place. Something tells me that train is out of the station and will be plowing forward full steam, no matter how much creativity the company has in its DNA.

The Volvo VNL, a heavy truck purpose-designed for North American roads

A while ago we checked out Super Truck II, a Department of Energy program that has been challenging the makers of Class 8 heavy trucks—the ones that haul up to 80,000 lbs (36.3 tonnes) of freight. Truck companies like Daimler Trucks North America and Volvo Trucks North America were challenged to build a big rig that used 50 percent less fuel than the machines on the road in 2017, and they stepped up.

It'll be a while before all of the efficiency improvements make their way onto production trucks, as that program has only just come to a close. But the truck makers are already starting to apply some of the lessons to production vehicles. Like Volvo's new VNL, a Class 8 long-haul truck that's been purpose-built just for our market.

"It's replacing the previous generation that had been around for several decades," explained Keith Brandis, VP of systems and solutions at VTNA. That was based on a global cab concept and design, where this was a completely new clean sheet for North America."

Solid-state polymer heat pump gets rid of the heat itself

Ars Technica - Thu, 05/09/2024 - 15:35

Enlarge (credit: Jorg Greuel)

Heat pumps are the most energy-efficient way of controlling indoor temperature. By moving heat between locations, they avoid the inefficiencies of generating heat in the first place. But that doesn't mean they can't be made more efficient.

Most current heat pumps rely on materials that exhibit large changes in temperature in response to changing pressures, but the energy required to pressurize them gets lost when they're cycled back to a low-pressure state, absorbing heat from their surroundings. That has gotten people interested in electrocaloric devices, where changes in temperature are driven by storing charges in a material. Since it essentially acts as a big capacitor, much of the electrical energy involved can be pulled back out as the system cycles.

But capacitors aren't especially mobile, so electrocaloric systems tended to use fluids to move heat into and out of the capacitor as it cycles. Now, however, researchers have developed an electrocaloric system that moves itself between hot and cold environments, radically simplifying the system and eliminating some of the energy required for it to operate. They even demonstrate it effectively cooling a computer chip.

Leaked FBI email stresses need for warrantless surveillance of Americans

A Federal Bureau of Investigation official recently urged employees to "look for ways" to conduct warrantless surveillance on US residents, an internal email obtained by Wired shows. FBI Deputy Director Paul Abbate's email was reportedly sent on April 20, the same day President Biden signed a bill that was criticized as a major expansion of warrantless surveillance under Section 702 of the Foreign Intelligence Surveillance Act (FISA).

Abbate's email seems to argue that FBI employees should make frequent use of warrantless surveillance on US people in order to justify the continued existence of the program. "To continue to demonstrate why tools like this are essential to our mission, we need to use them, while also holding ourselves accountable for doing so properly and in compliance with legal requirements," Abbate wrote, according to Wired.

Abbate oversees all FBI domestic and international investigative and intelligence activities. His email made reference to a new requirement that FBI personnel obtain prior approval from an FBI supervisor or attorney before making queries about US people.

Get up to $450 off a Google Pixel Tablet when you trade in your old iPad or Android slab

The company has a trade-in promotion that covers at least the cost of the Pixel Tablet for iPad owners — if not more, depending on which model you have. It works with Samsung tablets as well, but those trade-in values are lower. The Pixel Tablet costs $399 (without deals) for 128GB storage and no charging speaker dock.

The promo works with iPads as old as the sixth-generation model from six years ago. For that, Google will give you a surprising $399 — matching the Pixel Tablet’s base cost. That iPad model only cost $329 in 2018, so Google is overpaying by a lot for that one.

However, Google balances that with much worse offers for modern, high-end iPads. For example, the 12.9-inch iPad Pro with M2 chip (2022) only nets $450. Until this week (when the company launched a new iPad Pro and iPad Air), Apple sold that model for $1,099, so we don’t recommend that trade-in price. If you’re done with a high-end iPad from the last few years, you can likely sell it on places like eBay, Craigslist or Swappa for significantly more.

The Pixel Tablet stands out from its Android-running competitors by working with a charging speaker base that lets the device double as a smart display, making it much more versatile. Engadget’s Cherlynn Low thought that part overshadowed its core functionality as a tablet. “As a smart display, the Pixel Tablet mostly shines. It has a useful dashboard, an easy-to-read interface and impressive audio quality,” she wrote in our full review.

The tablet has a 10.95-inch display with a 2,560 x 1,600 resolution (276 PPI) and runs on a Google Tensor G2 chip. It weighs slightly over a pound and is lighter than Android rivals like the Galaxy Tab S8 and OnePlus Pad. Its back has a nano-ceramic coating that gives it a premium, glass-like feeling that you may not expect from a $399 device.

Accessories are where the Pixel Tablet stands out the most. Google’s Pixel Tablet Case, sold separately for $79, has a built-in kickstand that makes the slate more versatile. “What I love about the kickstand-hanger-combo is that it allows you to place the Tablet pretty much anywhere,” Low wrote in Engadget’s review. “So when I want to hang it off a kitchen cabinet to follow along with a recipe video or keep watching Love Is Blind for example, I can. And though the 2,560 x 1,600 LCD panel isn’t as vibrant as the OLED on Samsung’s Galaxy Tabs, it still produced crisp details and colorful images.”

The star accessory is Google’s $129 charging speaker dock, which you can use without removing the kickstand case. This product transforms the tablet into a smart display, potentially voiding the need for other smart home control hubs. The speaker has impressive sound for its size, making it easier to hear its responses if you aren’t right next to it.

Google’s fine print notes that the trade-in value will be finalized after receiving the tablet, and it could be lower if it determines the condition doesn’t match what you selected during the trade-in process. The refund will be processed on the credit card you used to buy the Pixel Tablet (or through Google Store credit if you return your purchase during that time).

The best midrange smartphones for 2024

Engadget - Thu, 05/09/2024 - 14:01

As one of Engadget’s resident mobile geeks, I’ve reviewed dozens of midrange phones and have found that a great smartphone doesn’t have to cost a fortune. Years of commoditization have brought features once exclusive to high-end devices – including big batteries, multi-camera arrays and high refresh rate displays – down to their more affordable siblings. While there are still some things you'll only find on flagship smartphones, you don't have to compromise as much anymore if you're looking to find the best buy at a lower price point. If you have less than $600 to spend, I can help you figure out what features to prioritize when trying to find the best midrange smartphone.

Editor’s note (5/9/24): Google has announced the Pixel 8a, its latest midrange smartphone. The 6.1-inch handset starts at $499 and, as expected, takes many of its cues from last year’s flagship Pixel 8 series. We’ll have a full review in the coming days and will update this guide accordingly. For now, you can check out our hands-on preview for more details on what to expect. Google says it’ll continue to sell the Pixel 7a, our current top pick, at a reduced price, so it may continue to be worthwhile. Most should hold off until we put the new Pixel through its paces, though.

What is a midrange phone, anyway?

While the term shows up frequently in articles and videos, there isn’t an agreed-upon definition for “midrange” beyond a phone that isn’t a flagship or an entry-level option. Our recommendations for the best midrange smartphones cost between $400 and $600 — any less and you should expect significant compromises. If your budget is higher, though, you should consider flagships like the Apple iPhone 13 and Samsung Galaxy S22.

What factors should you consider when buying a midrange smartphone?

Buying a new device can be intimidating, but a few questions can help guide you through the process. First: what platform do you want to use? If the answer is iOS, that narrows your options down to exactly one phone. (Thankfully, it’s great.) And if you’re an Android fan, there’s no shortage of compelling options. Both platforms have their strengths, so you shouldn’t rule either out.

Obviously, also consider how much you’re comfortable spending. Even increasing your budget by $100 more can get you a dramatically better product. And manufacturers tend to support their more expensive devices for longer. It’s definitely worth buying something toward the top limit of what you can afford.

Having an idea of your priorities will help inform your budget. Do you want a long battery life or fast charging speed? Do you value speedy performance above all else? Or would you like the best possible cameras? While they continue to improve every year, even the best midrange smartphones still demand some compromises, and knowing what’s important to you will make choosing one easier.

Lastly, pay attention to wireless bands and network compatibility. If you don’t want to worry about that, your best bet is to buy directly from your carrier. To make things easier, all the phones we recommend are compatible with every major US wireless provider and can be purchased unlocked. 

What won’t you get from a midrange smartphone?

Every year, the line between midrange and flagship phones gets blurrier as more upmarket features and specs trickle down to more affordable models. When we first published this guide in 2020, it was difficult to find $500 devices with waterproofing or 5G. Now, the biggest thing you might miss out on is wireless charging. Just remember to budget for a power adapter too – many companies have stopped including chargers with their smartphones. Performance has improved in recent years, but can still be hit or miss as most midrange phones use slower processors that can struggle with multitasking. Thankfully, their cameras have improved dramatically, and you can typically expect at least a dual-lens system on most midrange smartphones below $600.

Dell warns of “incident” that may have leaked customers’ personal info

Ars Technica - Thu, 05/09/2024 - 13:40

For years, Dell customers have been on the receiving end of scam calls from people claiming to be part of the computer maker’s support team. The scammers call from a valid Dell phone number, know the customer's name and address, and use information that should be known only to Dell and the customer, including the service tag number, computer model, and serial number associated with a past purchase. Then the callers attempt to scam the customer into making a payment, installing questionable software, or taking some other potentially harmful action.

Recently, according to numerous social media posts such as this one, Dell notified an unspecified number of customers that names, physical addresses, and hardware and order information associated with previous purchases was somehow connected to an “incident involving a Dell portal, which contains a database with limited types of customer information.” The vague wording, which Dell is declining to elaborate on, appears to confirm an April 29 post by Daily Dark Web reporting the offer to sell purported personal information of 49 million people who bought Dell gear from 2017 to 2024.

The customer information affected is identical in both the Dell notification and the for-sale ad, which was posted to, and later removed from, Breach Forums, an online bazaar for people looking to buy or sell stolen data. The customer information stolen, according to both Dell and the ad, included:

Discover why the world went quiet in new A Quiet Place: Day One trailer

Ars Technica - Thu, 05/09/2024 - 13:28

Lupita Nyong'o and Joseph Quinn must escape a Manhattan overrun by aliens in A Quiet Place: Day One.

Invading aliens transform a bustling New York City into a silent wasteland in the latest trailer for A Quiet Place: Day One, a prequel to the first two films in the hugely successful horror franchise.

(Mild spoilers for A Quiet Place and A Quiet Place: Part II below.)

As reported previously, the original film began in medias res over a month after an alien invasion set in early 2020. Sightless extraterrestrial creatures wiped out most of the humans and animals on Earth. They hunt by sound thanks to their hypersensitive hearing and are difficult to kill because they sport tough armored skin. The film centered on the Abbott family, struggling to survive a few months after the initial invasion. Dad Lee (John Krasinski) was an engineer focused on keeping his family alive each day. Wife Evelyn (Emily Blunt) was a doctor, pregnant with their fourth child.

The 2024 Moto G Stylus is a $400 mid-ranger with vegan leather

Ars Technica - Thu, 05/09/2024 - 13:18

Motorola's latest phone is the 2024 Moto G Stylus 5G. For fans of pen input there isn't much out there other than this and the Galaxy S Ultra line, but for $400 you can get a phone with a stowable stylus.

The design is just a bit interesting thanks to the "vegan leather" (that's a type of plastic) back, which gives the phone some personality. You get flat aluminum sides, a flat screen, and a hole-punch camera. Android does not have a lot of built-in stylus features, so you'll mostly be relying on whatever Motorola has cooked up; the website only shows a "Moto Note" app and the ability to send your drawings over instant messaging, plus there's whatever you can find on the Play Store.

This is a mid-range phone, so for the SoC, we have a Qualcomm Snapdragon 6 Gen 1. That's four Arm Cortex A78 cores and four Cortex A55 cores, built with a quite modern 4 nm process. There's a 6.7-inch, 120 Hz, 2400×1080 OLED display, 8GB of RAM, 256GB of storage, and a 5000 mAh battery with 30 W wired charging and 15 W wireless charging. Pictures will come from a 50 MP main camera, 13 MP wide-angle, or a front 32 MP camera. There's a MicroSD slot, headphone jack, in-screen fingerprint reader, stowable stylus (of course), and NFC. Wi-Fi only goes up to 802.11ac. That's "Wi-Fi 5" and is pretty old, but it will get the job done, I guess. The "IP52" dust- and water-resistant rating is also not great, promising only protection from some water drops at certain angles.
