Elon Musk has said that he will step down as CEO of Twitter once a suitable replacement can be found. On Sunday he ran a poll asking if he should step down, and the Twitter using public overwhelmingly told him to go. He didn’t immediately respond to the results of the poll, but by Tuesday he seemed to have accepted the will of the people, after originally suggesting that he might instead change it so that only paying users could vote in Twitter polls.

Of course there’s no timeline for Musk to hand over the reins yet. And as his Tweet say’s it will require finding “someone fooling enough to take the job.” Following a chaoticstring of badpress and the gutting of its staff it might be hard to attract high quality candidates to the position. But, the bar has been set exceedingly low under Musk’s tenure and just a simple change of face at the top could do a lot to improve Twitter’s image in the short term.

Of course, there is a chance that the change could be largely cosmetic. Musk tweeted that he planed to stay on and run the software and server teams. And there’s no indication that he plans to sell the company, which he bought in October for $44 billion and quickly took private. So it’s clear that he plans to still be involved in the company’s operation, but it’s unclear just how much.

When the Bahamas Attorney General’s office announced that it had arrested former FTX CEO Sam Bankman-Fried, it noted that the former FTX CEO was likely to be extradited at the request of the United States. Just over a week later, that prediction has come true: Bankman-Fried signed extradition papers on Tuesday afternoon.

According to an unsealed indictment, Bankman-Fried is facing 8 counts of conspiracy to commit wire fraud, commodities fraud, securities fraud, and more. Specifically, the SEC accuses the cryptocurrency founder of “orchestrating a massive, years-long fraud” for “his own personal benefit and to help grow his crypto empire.” The Department of Justice has accused him of attempting commodities and securities fraud, conspiring to defraud investors and breaking federal election laws for donating more to political groups than is legally allowed.

Bankman-Fried originally planned to fight extradition, but indicated on Monday that he would reverse course. Now, he will be returning to the US to face those charges, a decision that might be easier on him in the short term. When the former CEO was first arrested in the Bahamas, he was denied bail and deemed a flight risk. In the United States, it’s possible he could be released on bail.

Bankman-Fried has previously said that he “didn’t ever try to commit fraud,” and doesn’t believe he’s criminally liable for the fall of FTX. The New York Times reports that a defense lawyer representing Bankman-Fried in the Bahamas says that he’s returning to the US because he “wishes to put the customers right, and that is what has driven his decision.”

Delta Air Lines reportedly plans to offer free WiFi to all its passengers as soon as next year, according to the Wall Street Journal. The airline is already testing free wireless internet for members of its frequent-flier program, and it’s expected to expand significantly through 2023.

According to the report, Delta will start rolling out free WiFi “on a significant portion of its airplanes” before expanding the service to more of its fleet later next year. Once the program is available for all passengers, it will likely require a SkyMiles loyalty number to get online.

CEO Ed Bastian first announced the airline’s goal of free wireless access in 2018, and it recently stepped up testing. It currently uses Viasat and Intelsat (formerly Gogo) for internet access, and it reportedly plans to equip most of its US domestic fleet with Viasat service by the end of this year. JetBlue is the only major US airline currently offering free WiFi for all passengers.

The airline industry has tried for years to improve WiFi, testing with various providers and business models. However, the result is still a mess for customers: You might end up with different online requirements and pricing on two legs of the same flight, even with the same airline. Hopefully, Delta’s move will force other airlines to compete with free WiFi of their own — while cleaning up the process of accessing it.

The European Union plans to carry out a full-scale investigation of Broadcom’s $61 billion bid to buy VMware. Following a preliminary probe, the European Commission, the bloc’s executive branch, announced on Tuesday it believes the proposed acquisition may allow Broadcom to “restrict competition” in the markets for network interface cards, fiber channel host-bus adapters and storage adapters.

Specifically, the EU is concerned Broadcom may harm competition in those markets by limiting interoperability between rival hardware and VMware’s server virtualization software. It also worries the company could either prevent or degrade access to VMware’s software. The European Commission warns those actions “could lead to higher prices, lower quality and less innovation for business customers, and ultimately consumers.”

The Commission will also investigate whether Broadcom could hinder rivals like NVIDIA and Intel from developing their own smart network interface cards. Here it points to VMWare’s involvement in Project Monterey, an industry-wide effort the company announced in 2020. “Broadcom may decrease VMware’s involvement in Project Monterey to protect its own NICs revenues,” the Commission notes. “This could hamper innovation to the detriment of customers.” Another concern is that Broadcom could start bundling VMware’s virtualization software with its own mainframe and security tools, a move that would reduce choice in the market.

As one of the larger tech acquisitions of 2022, Broadcom’s bid to buy VMware was certain to draw scrutiny. The European Commission won’t necessarily block the deal, but the investigation could significantly delay the transaction and force concessions out of Broadcom. With today’s announcement, the Commission has 90 working days or until May 11th, 2023, to make a decision. If the deal were to fall through, it would be a bitter repeat of Broadcom’s 2018 attempt to buy chipmaker Qualcomm. While the circumstances and concerns were different, the company was forced to abandon the takeover after the Trump administration blocked the transaction.

After Google announced Stadia’s shutdown earlier this year, Ubisoft said it would help users transfer their purchases to PC. We got more detail today, as the publisher says it will provide free PC versions of all Ubisoft games bought on Stadia. The publisher also has other perks to make the transition as smooth as possible for jilted users of Google’s platform.

Anyone who bought Ubisoft games on Stadia should see the PC versions of those games appear in their Ubisoft Connect accounts at no extra cost. If your Stadia and Ubisoft accounts aren’t yet linked, connect them before Stadia shuts down on January 18th to get the PC games. Additionally, if you played Ubisoft games with cross-progression (complete list), you can pick up your progress on PC where you left off on Stadia.

Ubisoft notes any unspent virtual currency won’t transfer. Still, if you use it in Stadia before January 18th, the purchased items will move to PC (but only for games supporting cross-progression). Meanwhile, Stadia gamers who subscribed to Ubisoft+ Multi-Access (the company’s plan that lets you play on multiple devices) will receive an email telling them how to sign up directly through the Ubisoft+ website. As a bonus, subscribers will also get a free month of Ubisoft+. The publisher notes that US residents can continue streaming Ubisoft+ games through Amazon Luna, and those living elsewhere will get a discount on Ubisoft+ Multi-Access for six months. Additionally, If you bought or subscribed to any Ubisoft content on Stadia, you’ll receive one free month of GeForce Now Priority.

The perks are on top of Google’s refunds for all game purchases, so Ubisoft’s PC games are a no-charge consolation prize. Investing in a cloud-gaming platform requires customers to trust that their purchases won’t be all for naught if the platform fails, but at least Google and its partners are doing what they can to make it right.

After obtaining Senate approval last week, the No TikTok on Government Devices Act could become law thanks to the $1.7 trillion spending bill federal lawmakers unveiled early Tuesday morning. In addition to allocating more funding for Ukraine and earmarking $40 billion for natural disaster recovery efforts across the US, the sprawling 4,155-page bill includes provisions that would prohibit the use of TikTok on government-owned phones and other devices.

While some Republican lawmakers are pushing for a country-wide ban on TikTok, the spending bill stops short of prohibiting all government use of TikTok. If passed, the legislation would order the General Services Administration and Office of Management and Budget to create guidelines for staff at executive agencies to remove TikTok from government-owned devices by mid-February. The draft legislation allows congressional staff and elected officials to continue using the app. It also carves out some exceptions for law enforcement agents and officials.

“We’re disappointed that Congress has moved to ban TikTok on government devices — a political gesture that will do nothing to advance national security interests — rather than encouraging the Administration to conclude its national security review,” TikTok spokesperson Brooke Oberwetter told Engadget.

“The agreement under review by [The Committee on Foreign Investment in the United States] will meaningfully address any security concerns that have been raised at both the federal and state level. These plans have been developed under the oversight of our country’s top national security agencies — plans that we are well underway in implementing — to further secure our platform in the United States, and we will continue to brief lawmakers on them.”

The proposed ban comes after at least 11 states, including Georgia and South Dakota, prohibited TikTok on government-owned devices. Political concerns over TikTok hit a high earlier this month after FBI Director Chris Wray said China could use the app to collect user data. TikTok has tried to address those concerns. As of June, the app began routing all domestic traffic through Oracle servers in the US. At the same time, TikTok and parent company ByteDance pledged to delete US user data from their own data servers in the US and Singapore.

Apple has expanded its self-repair program once again. As noted by Six Colors and The Verge, folks in the US can now try to fix issues with the M1 iMac, M1 Mac mini, Mac Studio and Apple Studio Display themselves with genuine parts, repair manuals and tools.

The self-repair program is designed for those who have the time, patience, skills and confidence to carry out fixes at home, rather than taking their busted device to an Apple Store or third-party repair shop, or shipping it to Apple. You can buy all the parts and rent the tools you need, but at checkout you’ll need to enter a code from the relevant manual to show that you’ve actually read the document.

Apple debuted the Self Service Repair program in April by offering manuals and parts for select iPhone models in the US. Since then, it has expanded the program to Mac laptops and more territories. 

Apple introduced the program ahead of right-to-repair rules likely coming into force in the US and Europe. In 2021, President Joe Biden signed an executive order focused on bolstering competition in the US economy, partly in the tech sector. Among other things, it urged the Federal Trade Commission to ban “anticompetitive restrictions on using independent repair shops or doing DIY repairs of your own devices and equipment.” 

The agency has taken a stronger stance on such issues. In July, it announced settlements with three companies (including Weber and Harley-Davidson), which it accused of threatening to unlawfully void warranties if consumers used third-party repair parts or independent repair shops.

OpenAI, the Elon Musk-founded artificial intelligence startup behind popular DALL-E text-to-image generator, announced on Tuesday the release of its newest picture-making machine POINT-E, which can produce 3D point clouds directly from text prompts. Whereas existing systems like Google’s DreamFusion typically require multiple hours — and GPUs — to generate their images, Point-E only needs one GPU and a minute or two.

3D modeling is used across a variety industries and applications. The CGI effects of modern movie blockbusters, video games, VR and AR, NASA’s moon crater mapping missions, Google’s heritage site preservation projects, and Meta’s vision for the Metaverse all hinge on 3D modeling capabilities. However, creating photorealistic 3D images is still a resource and time consuming process, despite NVIDIA’s work to automate object generation and Epic Game’s RealityCapture mobile app, which allows anyone with an iOS phone to scan real-world objects as 3D images. 

Text-to-Image systems like OpenAI’s DALL-E 2 and Craiyon, DeepAI, Prisma Lab’s Lensa, or HuggingFace’s Stable Diffusion, have rapidly gained popularity, notoriety and infamy in recent years. Text-to-3D is an offshoot of that research. Point-E, unlike similar systems, “leverages a large corpus of (text, image) pairs, allowing it to follow diverse and complex prompts, while our image-to-3D model is trained on a smaller dataset of (image, 3D) pairs,” the OpenAI research team led by Alex Nichol wrote in Point·E: A System for Generating 3D Point Clouds from Complex Prompts, published last week. “To produce a 3D object from a text prompt, we first sample an image using the text-to-image model, and then sample a 3D object conditioned on the sampled image. Both of these steps can be performed in a number of seconds, and do not require expensive optimization procedures.”

If you were to input a text prompt, say, “A cat eating a burrito,” Point-E will first generate a synthetic view 3D rendering of said burrito-eating cat. It will then run that generated image through a series of diffusion models to create the 3D, RGB point cloud of the initial image — first producing a coarse 1,024-point cloud model, then a finer 4,096-point. “In practice, we assume that the image contains the relevant information from the text, and do not explicitly condition the point clouds on the text,” the research team points out. 

These diffusion models were each trained on “millions” of 3d models, all converted into a standardized format. “While our method performs worse on this evaluation than state-of-the-art techniques,” the team concedes, “it produces samples in a small fraction of the time.” If you’d like to try it out for yourself, OpenAI has posted the projects open-source code on Github.

Soccer megastar Lionel Messi finally secured the one prize that had eluded him during his illustrious career this weekend when Argentina won the World Cup. Afterward, the best player of the 21st century (yeah, I said it) added another record to his resume, as he now has the most-liked post on Instagram.

Messi posted a slideshow of him and his teammates celebrating after winning the World Cup. At the time of writing, the post has more than 65.8 million likes. The previous record-holder, a stock photo of an egg, claimed the top spot in early 2019 and currently has north of 57.3 million likes.

It’s not super surprising that Messi broke the Instagram record. As The Verge points out, the majority of the most-liked posts on the platform are from footballers, with the Paris Saint-Germain forward holding eight of the top 20 spots. 

Messi is also the second most-followed person on the platform with 404 million followers. Instagram’s own official account has the most followers overall. In second place, one spot ahead of Messi, is his old rival Cristiano Ronaldo with 520 million followers. Bet he’d rather have a World Cup, though.

National Institute of Standards and Technology (NIST) researchers have developed a way to monitor breathing based on tiny changes in WiFi signals. They say their BreatheSmart deep-learning algorithm could help detect if someone in the household is having breathing issues.

WiFi signals are almost ubiquitous. They bounce off of and pass through surfaces as they try to link devices with routers. But any movement will alter the signal’s path, including how the body moves as we breathe, which can change if we have any issues. For instance, your chest will move differently if you’re coughing.

Other researchers have explored the use of WiFi signals to detect people and movements, but their approaches required dedicated sensing devices and their studies provided limited data. A few years ago, a company called Origin Wireless developed an algorithm that works with a WiFi mesh network. Similarly, NIST says BreatheSmart works with routers and devices that are already available on the market. It only requires a single router and connected device.

The scientists changed the firmware on a router so that it would check “channel state information,” or CSI, more frequently. CSI refers to the signals that are sent from a device, such as a phone or laptop, to the router. CSI signals are consistent and the router understands what they should look like, but deviations in the environment, such as the signal being affected by surfaces or movement, modify the signals. The researchers got the router to request these CSI signals up to 10 times per second to gain a better sense of how the signal was being modified.

The team simulated several breathing conditions with a manikin and monitored changes in CSI signals with an off-the-shelf router and receiving device. To make sense of the data they collected, NIST research associate Susanna Mosleh developed the algorithm. In a paper, the researchers noted that BreatheSmart correctly identified the simulated breathing conditions 99.54 percent of the time.

Mosleh and Jason Coder, who heads up NIST’s research in shared spectrum metrology, hope developers will be able to use their research to create software that can remotely monitor a person’s breathing with existing hardware. “All the ways we’re gathering the data is done on software on the access point (in this case, the router), which could be done by an app on a phone,” Coder said. “This work tries to lay out how somebody can develop and test their own algorithm. This is a framework to help them get relevant information.”
