Roland has a new on-the-go podcasting setup with an eye-catching price. The company’s Go:Podcast studio includes a USB condenser mic (with support for four polar patterns) and a companion app that can stream to platforms like YouTube, Twitch and Facebook.

The company describes the Go:Podcast as “the simplest way to do high-quality live streaming with a mobile device.” For $140, you get the USB microphone and access to the companion app (iOS and Android), which supports live streaming, including dual-camera setups. The latter can work simultaneously with your smartphone’s front and back cameras, or you can pair a second “satellite” camera to complement your phone’s. It also supports wireless screen sharing for things like live-streaming mobile gameplay.

The microphone’s polar pattern options include cardioid (best for one person speaking), omni (multi-directional) and stereo (best for two people or musical performances). A fourth option lets you flip the stereo channels to match your video.

Somewhat confusingly, many of Roland’s product photos (like the one above) show a mini smartphone tripod and V-Moda headphones alongside the mic, but those accessories aren’t included. A Roland spokesperson clarified to Engadget that those were meant to illustrate an example of a complete mobile podcasting system with the mic and app at its center.

The Go:Podcast app includes perks like overlaying text and images, playing video clips and audio tracks, picture-in-picture and split screen. It has free-to-use background music tracks (which hopefully sound better than I imagine) along with stock photos and videos.

Roland’s $140 Go:Podcast studio will arrive in early May. You can learn more (and look out for more specific availability as its launch date approaches) at Roland’s website.

After asserting itself as an overshadowing presence in retail, Amazon is still experimenting with ways to leave a similar mark in groceries. The company’s latest tweak to its service lowers the minimum price for free grocery deliveries to $35. However, most customers using the service will also need to pay a $10 monthly subscription in addition to having a Prime membership ($15 monthly or $139 annually).

To participate, you must live in one of the 3,500 supported cities and towns in the US. (When signing up, it will let you know if your primary shipping address isn’t supported.) The service offers unlimited grocery deliveries from Amazon Fresh, the Amazon-owned Whole Foods and various local and specialty partners. Those include Cardenas Markets, Save Mart, Bartell Drugs, Rite Aid, Pet Food Express, Mission Wine & Spirits and more.

The subscription includes one-hour delivery windows where available, unlimited 30-minute pickup orders and priority access to the company’s Recurring Reservations. This feature lets you pick a guaranteed weekly grocery delivery window. To use it, you’ll need to pick your weekly two-hour slot at least 24 hours in advance.

Amazon

People using the Supplemental Nutrition Assistance Program (SNAP) and other government assistance programs can get the same grocery delivery benefits for half the price ($5 monthly). If you fall in that camp, you can get those perks without needing a Prime subscription on top of the subscription fee.

It remains to be seen if this latest iteration of the program will stick since Amazon’s strategy has been all over the place. Early last year, the company increased the minimum checkout price for free grocery deliveries from $35 to $150, then dropped it to $100 (while voiding the Prime requirement) about 10 months later. If you like this version of the program, cross your fingers that Amazon doesn’t change it again in a few months.

Before rolling out the program’s latest version on Tuesday, Amazon tested it in Columbus, OH, Denver, CO, and Sacramento, CA, in late 2023. The company says over 85 percent of survey respondents who used the service were “extremely” or “very” satisfied, leaving high marks for its convenience and savings on delivery fees.

You can see if the program is available in your area on Amazon’s groceries sign-up page. If it is, you can try it free for 30 days before paying.

Who hasn’t spent sleepless nights pondering what would happen if we applied Vilfredo Pareto's (the early 20th-century Italian economist) theories to Mario, the Mushroom Kingdom’s Italian high-jump champion and part-time elephant cosplayer? Data scientist Antoine Mayerowitz, PhD, tackled that age-old question, and the resulting work provides an objective way to tell us the best Mario Kart 8 racer combinations. Hint: It sure as hell ain’t Koopa Troopa.

When you break down the build options (including driver stats and various vehicle details) in Mario Kart 8 Deluxe, there are over 700,000 possible combinations. Yikes. But once you eliminate duplicates that differ only in appearance, you can narrow it down to “only” 25,704 possibilities. How do you narrow it down to find the best racer from there? Enter Mr. Pareto.

Pareto’s theories, most notably the Pareto front, help us navigate the complexities of choice. They can pinpoint the solutions with the most balanced strengths and the fewest trade-offs. Pareto’s work is about efficiency and effectiveness. Now we’re talking.

Nintendo

When choosing a Mario Kart racer, you have to consider their stats for speed, acceleration, handling, weight, offroad and mini turbo. That’s a lot to weigh.

Even if you decide that speed and acceleration are the most important, you’re still left with imbalances. For example, it’s tempting to go all in on speed (like Bowser or Wario), but they have weak acceleration. However, if you prioritize acceleration instead (such as Baby Mario or Dry Bones), you may be left with quick surges that plateau at a lousy top speed.

Meanwhile, some racers are always dominated in the most important stats — meaning their balance of speed and acceleration consistently come out behind. Koopa is one example of that, so don’t pick him if you care about winning. (But you can absolutely choose him because he has cute bug eyes and a snazzy shell.)

Nintendo

Mayerowitz’s Pareto front analysis lets you narrow your possibilities down to the 14 most efficient. And it turns out the game’s top players were onto something: One of the combinations with the most ideal balance of speed, acceleration and mini-turbo is Cat Peach driving the Teddy Buggy, roller tires and cloud glider — one already favored among Mario Kart 8 competitors.

Of course, if that combination isn’t your cup of tea, there are others that allow you to stay within the Pareto front’s optimal range. As Eurogamer points out, Donkey Kong, Wario (my old standby, mostly because he makes me laugh) and Princess Peach are often highlighted as drivers, and you can use Mayerowitz’s data fields to find the best matching vehicles. Keep in mind that others have identical stats, so racers like Villager (female), Inkling Girl and Diddy Kong are separated only by appearances.

To find your ideal racer, you can head over to Mayerowitz’s website. There, you can enter your most prized stats and view the combos that give you the best balance (those highlighted in yellow), according to Pareto’s theories.

If you’re looking to automate more of your home cleaning setup, iRobot’s flagship Roomba Combo J9+ is on sale for $400 off. The vacuum-mop hybrid robot, which only arrived last fall, has a redesigned dock that automatically empties debris and refills the device’s mopping liquid. Usually $1,399, Wellbots has the Roomba Combo J9+ for $999 with coupon code ENGA400.

The Combo J9+, Engadget’s pick for the best vacuuming-mopping robot, has an upgraded motor and four-stage cleaning system that takes multiple pass-throughs across your carpets and floors. This version also adds dual rubber brushes for better suction and pressurized scrubbing. Its motor automatically lifts the mop pads when it reaches carpets and rugs to help keep them dry.

The robot requires minimal setup, and its new Clean Base can automatically refill the water tank, leaving you with fewer things to worry about. The base doubles as a storage unit and appearing less like a gadget’s charging station and more like living room furniture. Setup is as simple as adding water and cleaning solution to a reservoir and attaching a mop pad. Upkeep is limited to swapping mop pads and leaning the vacuum’s bristles and dust bin.

The Combo J9+ ships with Roomba’s OS 7, a new software update that streamlines more of the cleaning process. Its Dirt Detective feature remembers your home’s dirtiest areas and tackles those first on subsequent cleanings.

The software has an automated setting that saves bathrooms for last, so you don’t have to worry about tracking grime and bacteria to other parts of your home. (You can manually override that if you want it to get to the bathroom earlier.) Speaking of bathrooms, the machine includes iRobot’s Pet Owner Official Promise (P.O.O.P.), which guarantees a replacement unit if your device accidentally sweeps up pet waste.

iRobot

For those who don’t mop much, Wellbots also has the standard Roomba J9+ for $300 off ($599) when you use code ENGA300. It includes all the vacuum-related features from the more expensive Combo variant, including a three-stage cleaning system, multi-surface rubber brushes and stronger suction.

Finally, the previous-generation Roomba Combo j7+ offers an older (but still high-end) vacuum-mop cleaning robot for $200 off with coupon code ENGA200. Although you lose some of the features of the newer model, it still has a 96.4 percent debris removal rate, obstacle avoidance, and a four-stage cleaning system. Its cleaning toolbox includes an edge-sweeping brush, dual multi-surface rubber brushes, power-lifting suction and the mop. The device can even return to its base when it’s full and continue emptying itself for up to 60 days, leaving you to focus on things that aren’t cleaning.

Amazon appears to have nixed its Prime Video-only plan in the US and UK. Cord Busters reports that the little-known subscription, introduced in 2016, is no longer available to new users in either country. Those trying to sign up for the previously $8.99 monthly plan (£5.99 monthly in the UK) are now directed to the landing page for a full Amazon Prime membership.

The Prime Video plan launched eight years ago, priced to undercut Netflix’s (at the time) $9.99-a-month subscription price for standard HD streaming on up to two devices. Although the option stuck around for close to a decade, Amazon increasingly buried it, making it impossible to sign up for on mobile devices. It was also increasingly difficult to find on desktops, where you had to navigate to an easy-to-miss “See more plans” section of the Prime sign-up page.

The Prime Video plan never even got a price increase during that time, further illustrating how obscure Amazon apparently wanted it to remain. Now, it appears to be gone for good. Cord Busters says it was recently removed in the US and axed from Amazon UK earlier this week.

Your subscription should still work if you’re already on the Prime Video-only plan. But if you cancel it or switch to the full Prime membership, don’t expect to see an option to return to it.

Engadget reached out to Amazon to ask about the change. We’ll update this article if we hear back.

Prime Video is home to Fallout, which premiered earlier this month. We found it to be one of the best video game adaptations to date, in the vein of The Last of Us. 

If you watch movies and TV on a 1080p screen, the Chromecast with Google TV (HD) provides a rock-solid streaming experience on the cheap. This is the HD version of Engadget’s top choice for streaming devices. Today, Amazon has it for $10 off, letting you pick up the HDR10-capable streaming stick for only $20, nearly a record-low price.

The Chromecast with Google TV (HD) plugs directly into an open HDMI port on your TV. (There’s an optional power adapter with a USB cable if your TV can’t supply enough juice.) If you have a 4K television, you’re better off with the more expensive model designed for higher-res displays. But for HD screens, this model is hard to beat. It offers the same terrific user experience as the high-end model, only less expensive and downscaled for 1080p.

Setup is quick and easy. You scan a QR code with your phone to begin the sign-in process in the Google Home app. (That’s also where you add your Wi-Fi network.) So, you don’t need to worry about entering long email addresses and passwords using the remote and a clunky onscreen keyboard.

The device has relatively lightweight specs (1.5GB of RAM and an Amlogic S805X2 chip) that may reveal some nearly imperceptible lag when navigating the UI, especially right after startup. But it provides smooth performance when it matters most: playing content.

The software streamlines things as much as possible, including a Live tab that draws from a handful of streaming services to let you resume or jump into new content straight from the home screen. Google advertises support for over 700,000 movies and TV episodes, and you can install just about any streaming service you can name, including Netflix, Prime Video, Apple TV+, Max, Peacock, YouTube TV and much more.

The remote includes a built-in mic and a dedicated Google Assistant button. The latter lets you control TV content and smart home features with your voice. It also has standard IR integration, so you can control some of your TV’s essential functions and potentially leave its remote in a drawer.

If you don’t want to wait for Amazon’s shipping, Target has the same deal. If your local stores have them in stock, you could get instant gratification while saving five percent on your purchase if you check out using a Target RedCard.

The News/Media Alliance, formerly the Newspaper Association of America, asked US federal agencies to investigate Google’s removal of links to California news media outlets. Google’s tactic is in response to the proposed California Journalism Preservation Act (CJPA), which would require it and other tech companies to pay for links to California-based publishers’ news content.

The News/Media Alliance, which represents over 2,200 publishers, sent letters to the Department of Justice, Federal Trade Commission and California State Attorney General on Tuesday. It says the removal “appears to be either coercive or retaliatory, driven by Google’s opposition to a pending legislative measure in Sacramento.”

The CJPA would require Google and other tech platforms to pay California media outlets in exchange for links. The proposed bill passed the state Assembly last year.

In a blog post last week announcing the removal, Google VP of Global News Partnerships Jaffer Zaidi warned that the CJPA is “the wrong approach to supporting journalism” (because Google’s current approach totally hasn’t left the industry in smoldering ruins!). Zaidi said the CJPA “would also put small publishers at a disadvantage and limit consumers’ access to a diverse local media ecosystem.” Nothing to see here, folks: just your friendly neighborhood multi-trillion-dollar company looking out for the little guy!

Google described its link removal as a test to see how the bill would impact its platform:

“To prepare for possible CJPA implications, we are beginning a short-term test for a small percentage of California users,” Zaidi wrote. “The testing process involves removing links to California news websites, potentially covered by CJPA, to measure the impact of the legislation on our product experience. Until there’s clarity on California’s regulatory environment, we’re also pausing further investments in the California news ecosystem, including new partnerships through Google News Showcase, our product and licensing program for news organizations, and planned expansions of the Google News Initiative.”

In its letters, The News/Media Alliance lists several laws it believes Google may be breaking with the “short-term” removal. Potential federal violations include the Lanham Act, the Sherman Antitrust Act and the Federal Trade Commission Act. The letter to California’s AG cites the state’s Unruh Civil Rights Act, regulations against false advertising and misrepresentation, the California Consumer Privacy Act and California’s Unfair Competition Law (UCL).

“Importantly, Google released no further details on how many Californians will be affected, how the Californians who will be denied news access were chosen, what publications will be affected, how long the compelled news blackouts will persist, and whether access will be blocked entirely or just to content Google particularly disfavors,” News/Media Alliance President / CEO Danielle Coffey wrote in the letter to the DOJ and FTC. “Because of these unknowns, there are many ways Google’s unilateral decision to turn off access to news websites for Californians could violate laws.”

Google has a mixed track record in dealing with similar legislation. It pulled Google News from Spain for seven years in response to local copyright laws that would have required licensing fees to publishers. However, it signed deals worth around $150 million to pay Australian publishers and retreated from threats to pull news from search results in Canada, instead spending the $74 million required by the Online News Act.

Google made more than $73 billion in profits in 2023. The company currently has a $1.94 trillion market cap.

Amazon published a blog post on Wednesday providing an update about its Just Walk Out technology, which it reportedly pulled from its Fresh grocery stores earlier this month. While extolling Just Walk Out’s virtues as a sales pitch to potential retail partners, the article lists a startlingly minuscule number of (non-Amazon) stores using the tech. There are now “more than 140 third-party locations with Just Walk Out technology in the U.S., UK, Australia, and Canada.”

Mind you, that isn’t the number of companies or retail chains licensing the tech; that’s the total number of locations. Nor is that the tally in one state or even one country. In four countries combined — with a total population of about 465 million — Just Walk Out is being used in “more than 140 third-party locations.”

On average, that means there’s one third-party Just Walk Out store for every 3.3 million people in those four countries. (They must be busy!) By contrast, there are over one million retail locations in the US, and, as of 2019, Starbucks had 241 locations in New York City alone, and there are over one million

Amazon had reportedly already planned to remove Just Walk Out tech from its Fresh grocery stores for roughly a year because it was too expensive and complicated for larger retail spaces to run and maintain. The company now pitches its tech as ideal for smaller convenience stores with fewer customers and products — like its own Amazon Go stores, which it has been busy shutting down over the last couple of years.

Amazon

The company reportedly gutted the team of developers working on Just Walk Out tech earlier this month. (You get one guess as to how the laid-off workers were instructed to leave the office.) As part of recent layoffs from Amazon’s AWS unit and Physical Stores Team, the company allegedly left only “a skeleton crew” to work on the tech moving forward. A skeleton crew to maintain a skeleton sounds about right.

In fairness, some of those locations are at high-traffic venues. That includes nine merch stores at Seattle’s Lumen Field (home to the Seahawks and Sounders), near Amazon’s headquarters. Delaware North, a large hospitality and entertainment company, has opened “more than a dozen” stores using the tech. Amazon says stores adopting Just Walk Out have reported increased transactions, sales and customer satisfaction.

Despite the reported gutting of Just Walk Out’s development team, Amazon says it “continues to invent the next generation of this technology to improve the checkout experience for large-format stores.” Its next steps include improving latency for “faster and more reliable receipts,” new algorithms to recognize customer actions and new sensors better.

If the reports about layoffs are accurate, the handful of remaining Just Walk Out developers will have their work cut out for them.

A data scraping service is selling information on what it claims to be 600 million Discord users. A report from 404 Media details Spy Pet, an online service that gathers, stores and sells troves of information from the social platform. But have no fear: It markets its services to totally trustworthy paying clients like law enforcement, AI model trainers or your average person curious about “what their friends are up to.” Why ask them when you can simply purchase and download a copy of their Discord activity?

For as little as $5 in cryptocurrency, Spy Pet lets you access data about specific users, such as which servers they participate in, what messages they’ve sent and when they joined or left voice channels. It claims to have information on an alleged 600 million users across 14,000 Discord servers and three billion messages.

As for what inspired Spy Pet, its creator suggested it’s a classic case of doing what one enjoys and pushing personal boundaries. “I like scraping, archiving, and challenging myself,” the creator told 404 Media. “Discord is basically the holy grail of scraping, since Discord is trying absolutely anything to combat scraping.”

Some people run a 5K, set a weight-loss goal or take up pickleball. Others start a social scraping service that sells data to the feds, AI companies and creepy exes. To each their own!

404 Media says the database lets you search for specific users. For each search result, a page shows the servers the user has joined (at least among those Spy Pet monitors), their connected accounts, a table showing their recent messages (including the server name, time stamps and the message itself) and their voice channel entry and exit times. Paying customers can conveniently export their prey’s — or “friend’s” — chats into a CSV file.

Discord says it’s investigating Spy Pet and weighing its options. “Discord is committed to protecting the privacy and data of our users,” a company spokesperson wrote in an email to Engadget. “We are currently investigating this matter. If we determine that violations of our Terms of Service and Community Guidelines have occurred, we will take appropriate steps to enforce our policies. We cannot provide further comments as this is an ongoing investigation.”

On March 8, a piece of space debris plunged through a roof in Naples, FL, ripped through two floors and (fortunately) missed the son of homeowner Alejandro Otero. On Tuesday, NASA confirmed the results of its analysis of the incident. As suspected, it’s a piece of equipment dumped from the International Space Station (ISS) three years ago.

NASA’s investigation of the object at Kennedy Space Center in Cape Canaveral confirmed it was a piece of the EP-9 support equipment used to mount batteries onto a cargo pallet, which the ISS’ robotic arm dropped on March 11, 2021. The haul, made up of discarded nickel-hydrogen batteries, was expected to orbit Earth between two to four years (it split the difference, lasting almost exactly three) “before burning up harmlessly in the atmosphere,” as NASA predicted at the time. Not quite.

The roof-piercing debris was described as a stanchion from NASA flight support equipment used to mount the batteries onto the cargo pallet. Made of the metal alloy Inconel, the object weighs 1.6 lbs and measures 4 inches tall and 1.6 inches in diameter.

Otero told Fort Meyers CBS affiliate WINK-TV that he was on vacation when his son told him that an object had pierced their roof. “I was shaking,” he said. “I was completely in disbelief. What are the chances of something landing on my house with such force to cause so much damage. I’m super grateful that nobody got hurt.”

NASA says it will investigate the equipment dump’s jettison and re-entry to try to figure out why the object slammed into Otero’s home instead of disintegrating into flames. “NASA specialists use engineering models to estimate how objects heat up and break apart during atmospheric re-entry,” the space agency explained in a news release. “These models require detailed input parameters and are regularly updated when debris is found to have survived atmospheric re-entry to the ground.”

Most space junk moves extremely fast, reaching up to 18,000 mph, according to NASA. It explains, “Due to the rate of speed and volume of debris in LEO, current and future space-based services, explorations, and operations pose a safety risk to people and property in space and on Earth.”
