WhatsApp has rolled out a new desktop client for Windows that brings its calling features up to par with its counterpart for mobile. In an announcement, Meta chief Mark Zuckerberg said the new app enables users to host end-to-end encrypted video calls with up to eight participants. For audio calls, up to 32 people can participate, making it a viable choice for company meetings and family reunions where all the aunts, uncles and extended relatives can join in. WhatsApp says it will increase these limits further to allow for even larger calls in the future. 

In addition to announcing the new client's improved calling features, it also touched upon some of its other recent upgrades. The messenger updated its multi-device capabilities to make it easier and faster to link new devices to user accounts. WhatApp also enabled better syncing so that people can simultaneously access their chats on up to four linked devices. 

The service launched true multi-device syncing in 2021, allowing people to access their accounts even if their phone is offline or nowhere nearby. After that, WhatsApp must have recognized the need for better apps on different platforms for users to be able to enjoy using the messenger on multiple devices. WhatsApp first released a native app for Windows 10 in 2022, and back in January, it made the beta version of its native app for Mac available to all users. Since the latter was optimized for Mac hardware, it works better than the previous web-wrapped app for Apple's desktop OS.

Meta's publishing arm for virtual reality games is now officially called Oculus Publishing. It's a completely different division from Oculus Studios, which is the company's label for first-party games. Oculus Publishing will instead support partner developers with conceptualization, funding, technological help, as well as promotion and merchandising. While the name is new, the division itself isn't. It had previously funded and supported over 300 titles, including Among Us VR, Bonelab and The Walking Dead: Saints & Sinners.

The company has also revealed that Oculus Publishing has over 150 titles currently in development, which bodes well for the Quest 3 that's expected to arrive this year. Previous reports suggested that the next-gen Quest will be thinner and more powerful than its predecessor and will have mixed reality capabilities. That could mean that some of these new titles — Meta unfortunately didn't name any of them in its announcement — may have features that weren't possible for older games. 

At the moment, users still have more than 500 titles to choose from in the Meta Quest Store, and they seem to be doing well. Last year, the company said the games and apps on the store had surpassed $1.5 billion in revenue, with 40 titles grossing over $10 million. In addition, the number of titles that had reached $20 million in revenue had doubled year-over-year.

The Securities and Exchange Commission has cracked down on the businesses of crypto entrepreneur Justin Sun and has charged him for the unregistered offer and sale of the tokens Tronix and BitTorrent. If those tokens sound familiar even to non-hardcore crypto enthusiasts, it's because several celebrities had promoted them on social media — and now they're also being charged by the agency. According to the SEC, eight celebrities, including Lindsay Lohan, Jake Paul, Soulja Boy, Ne-Yo and Akon, illegally promoted the tokens online without disclosing that they were paid to do so. 

"...Sun paid celebrities with millions of social media followers to tout the unregistered offerings, while specifically directing that they not disclose their compensation. This is the very conduct that the federal securities laws were designed to protect against regardless of the labels Sun and others used," Gurbir S. Grewal, Director of the SEC's Division of Enforcement, said in a statement. 

All celebrities charged, with the exception of Soulja Boy and musician Austin Mahone, have agreed to pay a collective amount of $400,000 in penalties to settle the charges. It's not the first time the SEC went after celebrities shilling crypto on social media — it previously charged Kim Kardashian and NBA Hall of Famer Paul Pierce for posting about EthereumMax's EMAX tokens without revealing that they had been paid for the promotion. Kardashian paid $1.26 million to settle the charges against her, while Pierce paid $1.4 million. 

As for Sun himself, the SEC accused him of violating antifraud and market manipulation provisions of the federal securities laws. The agency said he offered the tokens as investments through unregistered bounty programs that prompted participants to promote the tokens on social media and to recruit others. In addition, the SEC also accused Sun of directing employees to artificially inflate the value of Tronix by simultaneously selling and purchasing the token to make it appear actively traded. 

"As alleged in the complaint," Grewal said, "Sun and others used an age-old playbook to mislead and harm investors by first offering securities without complying with registration and disclosure requirements and then manipulating the market for those very securities."

In February, Opera shared plans to integrate generative AI capabilities into its web browser using ChatGPT. Now, the independent browser maker has launched sidebar integration for both ChatGPT and ChatSonic and has introduced another feature called smart AI Prompts. To get these features, you'll need to update your browser and then go to Easy Setup to toggle on the "AI Prompts" option at the bottom. For the Opera GX browser for games, you also need to have the Early Bird option enabled in your browser settings. 

Once the option is switched on, you'll see buttons for the chatbots on your sidebar, which you can click if you want to launch them within the browser. Take note that you'll still need to log in to be able to use either. You can also launch the chatbots by using the browser's new contextual AI Prompts that show up when you highlight text on a website. 

The prompts suggest different ways you can use the chatbots with the text on page, such as turning a chunk of text into a soap opera or a football commentary and using information to create quiz questions. (I turned our post about the new quests feature for Horizon Worlds VR into a soap opera, and let's just say it wouldn't feel out of place in Dynasty. Or Riverdale.) Green prompts use ChatGPT, while purple prompts use ChatSonic's service.

Opera says these are merely parts of the first stage of its Browser AI plan and that the features launching with the second stage will be based on its own GPT-based browser AI engine. A lot of tech companies are rushing to get their own AI products out after ChatGPT shot up in popularity and Microsoft, a long-time OpenAI backer, launched its Bing Chat AI and Edge Copilot tools. Baidu unveiled its ERNIE bot a few days ago, while Google just made its chatbot Bard more widely available in the US and the UK. Opera's, announcement, however, shows that even smaller companies are keen to gain entry and secure their position in the AI race as early as possible.

You may soon see ads on Instagram in places you didn't in the past. The Meta-owned app has started testing a couple of new ad placements meant to give businesses more ways to get discovered. One of those experimental placements puts ads in its search results. When you search for a particular term on the app — say "makeup" — posts marked "sponsored" will show up in the feed you can scroll through when you tap on any of the actual results. In its announcement, Instagram said it plans to roll out the placement globally in the coming months.

In addition, the app has teamed up with certain brands to test a format that would give businesses the power to remind or notify you of future events or launches. When you opt into the app's "reminder ads" for a particular event, you'll get notifications from Instagram one day before, 15 minutes before and when the event begins. These reminders will appear like any other Instagram notification and will show up on your lock screen.

Ads are Meta's lifeblood, and the introduction of new ways to earn from them comes as no surprise after a year that saw the company's quarterly revenue shrink for the first time. For the fourth quarter of 2022, for instance, the company reported an advertising revenue of $31.25 billion, down from $32.64 billion for the same quarter in 2021. Its year-on-year ad revenue was down, as well, from $114.93 billion in 2021 to $113.64 billion in 2022. Meta has been severely tightening belt in recent months and let more than 11,000 workers go in November in its first ever mass layoffs. Just a few days ago, company chief Mark Zuckerberg announced that Meta is laying off another 10,000 workers and will restructure its divisions in April and May.

ChatGPT went offline and temporarily became inaccessible on Monday after some users discovered that they could see the titles of other people's chat histories. People posted screenshots of their ChatGPT UI on social networks like Reddit and Twitter, showing sidebars populated with chats they said weren't theirs. While they could only see the titles and not the entirety of other people's conversations, the incident still highlights the need to be mindful when it comes with sharing details with or writing up questions for the chatbot. 

An OpenAI spokesperson told Bloomberg that the company temporarily disabled ChatGPT after it became aware of these reports. Apparently, a bug in an open source software that the company has yet to name had caused the issue, but OpenAI is still investigating to figure out what triggered it exactly.

Based on the company's incident report, it shut down ChatGPT on Monday morning and then fully restored the service 10 hours later after rolling out a fix. As of this writing, though, chat histories are still unavailable. OpenAI posted a note saying as much on the sidebar, along with an assurance that it's "working to restore this feature as soon as possible." The company has not announced an ETA for the feature's restoration. 

You most likely know Duolingo as an app you can fire up when you want to learn a new language or at least familiarize yourself with the local tongue of a place you're visiting. It has ventured into other subject matters over the years, though, and now it looks like the company is also hoping to be the one people turn to when they want to learn about music. According to a job posting (seen by TechCrunch), Duolingo has a small team that's currently working to build an app for teaching music. 

The job ad is for an "expert in music education who combines both theoretical knowledge of relevant learning science research and hands-on teaching experience." Whoever gets the job will be in charge of making sure that the app is "well-grounded in learning science." They have to translate "research findings into concrete ideas" that can be used for "learning by doing" activities that Duolingo is known for. They also have to take the lead on curriculum development, which signifies that the app is still in its very early stages. 

If and when Duolingo's Music app comes out, it will join the company's growing list of learning applications that include its ABC app, which teaches kids how to read and write. It also has an English Test app for language certification and a Math app that uses colorful animations and interactive exercises to help people learn multiplication, division, fractions, geometry and measurements. As TechCrunch notes, the company is most likely diversifying to ensure its survival and income growth in the future. And its plan seems to be working so far: In its earnings report (PDF) for the fourth quarter of 2022, Duolingo revealed that it enjoyed a 67 percent increase in paid subscribers from the year before. 

Back in 2021, a law took effect in New York City that requires businesses to post conspicuous signs if they're collecting customers' biometric information, such as their facial scans and fingerprints. Now, Amazon is facing a proposed class-action lawsuit that accuses the company of failing to inform customers at its Go cashierless stores that it was collecting their biometrics. 

In the lawsuit (PDF), filed by Alfredo Alberto Rodriguez Perez, the plaintiff argues that Go stores constantly use customers' biometrics "by scanning [their palms] to identify them and by applying computer vision, deep learning algorithms, and sensor fusion that measure the shape and size of each customer’s body to identify customers, track where they move in the stores, and determine what they have purchased." It said the company only put up signs about its biometric tracking activities over a year after the law went into effect. 

Amazon's Go stores give shoppers the option to take whatever product they have off shelves and walk out without the need to check out. To be able to enter these stores, customers will need to scan a code from the Amazon app with a connected credit card. However, some locations offer Amazon One, the e-commerce giant's palm-based identity and payment service, as an entry option. The plaintiff's complaint said the sign informs customers that Amazon will not be collecting their biometrics unless they choose to sign up for Amazon One. However, "Amazon Go stores do collect biometric identifier information on every single customer, including information on the size and shape of every customers body," the complaint argues.

In a statement sent to NBC News, an Amazon spokesperson defended the company's practices and technologies. They explained that Amazon does not use facial recognition, and any system it uses to identify shoppers inside its Go stores don't constitute biometric tech. "Only shoppers who choose to enroll in Amazon One and choose to be identified by hovering their palm over the Amazon One device have their palm-biometric data securely collected," they insisted, "and these individuals are provided the appropriate privacy disclosures during the enrollment process."

The lawsuit's outcome could then depend on whether the court sees someone's body shape and size as biometric information. In the complaint, the plaintiff quotes NYC Admin Code 22-1201's definition of a biometric identifier in context of the law as "a physiological or biological characteristic that is used by or on behalf of a commercial establishment, singly or in combination, to identify, or assist in identifying, an individual, including, but not limited to: (i) a retina or iris scan, (ii) a fingerprint or voiceprint, (iii) a scan of hand or face geometry, or any other identifying characteristic."

Discord is finally giving you the power to customize your desktop app's interface with various themes for its latest beta test. The messaging app has introduced Themes — one of its most requested features — with 16 pre-made options to choose from. The not-so-good news? You'll only be able to apply them if you're paying for Nitro, its most expensive subscription option. 

Nitro does have other perks, including a bigger file-sharing limit, 4K and 60fps streaming, as well as the ability to send messages up to 4,000 characters in length. But if you don't really need any of them, it's a matter of deciding whether it's worth paying $10 a month or $100 a year for the subscription tier just to be able to access Discord's themes. 

In case you have been waiting for the feature to drop and do decide to pay for Nitro, you can choose from the available color schemes by going to Appearance under Settings. You'll now see a new Color section under the existing Light and Dark themes, where you can find the main 16 choices. There's apparently another hidden color scheme you can see when you click on the Preview Themes button to test out each option before applying one. Thankfully, Discord is allowing you to use the preview button even if you don't have an existing Nitro subscription, so you can at least check out what's available before you make a purchase. 

A new group of Phantom Thieves will be stealing hearts in Tokyo. Black Wings Game Studio, the developer owned by Chinese company Perfect World Games, has unveiled a new mobile game set in the Persona 5 universe. The previous spinoffs of the title, Persona 5 Strikers and Dancing in Starlight, feature the original gang, but this one comes with a brand new cast of characters. While it wasn't created by Atlus itself, Persona: Phantom of the Night (or Persona 5: The Phantom X, shortened as P5X) had SEGA's blessing. It was also developed under the supervision of P-Studio, the team behind the mainline Persona games. 

So far, its trailers show us a red-haired protagonist who's juggling high school life and Metaverse thievery, a brown-haired girl reminiscent of P4's Chie and a talking owl who, like Morgana, can transform into a getaway vehicle. The developer has also released character artwork for another female character with long black hair and another for Igor's new assistant in the Velvet Room. 

According to the game's announcement, franchise character designer Shigenori Soejima created the game's protagonist and exclusive Persona. And if you watch the trailer below, you'll see that Black Wings was able to capture the look and feel of the original Persona 5 game quite well. It uses the same gameplay and battle effects, and it features the same victory close-ups, as well as the popular P5 battle soundtrack Wake Up, Get up, Get Out There.

Unlike the original Persona 5 game, P5X will be free to play, which means it will have in-app purchases. It will be available to beta testers on Android, iOS and Windows (as a port) starting on March 29th, but only in China. The developer has yet to announce if it will be released outside the region.
