Cloudflare Detects One of the Largest DDoS Attacks on Record Targeting Crypto Platform (therecord.media) 8

Internet infrastructure company Cloudflare said this week that it mitigated one of the largest volumetric distributed denial of service (DDoS) attacks that has been recorded to date. From a report: Cloudflare said it detected and mitigated a 15.3 million request-per-second (rps) DDoS attack earlier this month -- making it one of the largest HTTPS DDoS attacks on record. Volumetric DDoS attacks differ from traditional bandwidth DDoS attacks where attackers attempt to exhaust and clog up the victim's internet connection bandwidth. Instead, attackers focus on sending as many junk HTTP requests to a victim's server in order to take up precious server CPU and RAM and prevent legitimate users from using targeted sites. Cloudflare previously announced that it stopped the largest DDoS attack on record in August 2021, when it mitigated a 17.2 million HTTP requests/second (rps) attack, a figure that the company described as almost three times larger than any previous volumetric DDoS attack that was ever reported in the public domain. Earlier this month, the company said it stopped an attack targeting a company in the cryptocurrency space.

Twitter Admits It Overstated Users for Years (axios.com) 113

Twitter on Thursday reported mixed first-quarter earnings, missing Wall Street expectations on revenue but adding users. It also admitted to over-counting some monetizable daily active users between Q1 2019 and Q4 2021. From a report: Analysts were expecting the tech giant to post weak results, given that its board finalized a takeover deal with Elon Musk earlier this week. This could be Twitter's last earnings report as a publicly traded company. The company brought in $1.2 billion in revenue last quarter, just shy of analyst estimates. Other ad-supported tech giants also missed Q1 revenue expectations in response to macroeconomic headwinds impacting the ad market. Twitter also said it accidentally over-counted the number of monetizable daily active users because of a feature that allowed people to link multiple separate accounts together in order to conveniently switch between them. It counted those two separate accounts as two users for more than three years.

North Koreans Are Jailbreaking Phones To Access Forbidden Media (wired.com) 23

An anonymous reader quotes a report from Wired: For most of the world, the common practice of "rooting" or "jailbreaking" a phone allows the device's owner to install apps and software tweaks that break the restrictions of Apple's or Google's operating systems. For a growing number of North Koreans, on the other hand, the same form of hacking allows them to break out of a far more expansive system of control -- one that seeks to extend to every aspect of their lives and minds. On Wednesday, the North Korea-focused human rights organization Lumen and Martyn Williams, a researcher at the Stimson Center think tank's North Korea -- focused 38 North project, together released a report on the state of smartphones and telecommunications in the Democratic People's Republic of Korea, a country that restricts its citizens' access to information and the internet more tightly than any other in the world. The report details how millions of government-approved, Android-based smartphones now permeate North Korean society, though with digital restrictions that prevent their users from downloading any app or even any file not officially sanctioned by the state. But within that regime of digital repression, the report also offers a glimpse of an unlikely new group: North Korean jailbreakers capable of hacking those smartphones to secretly regain control of them and unlock a world of forbidden foreign content.

Learning anything about the details of subversive activity in North Korea -- digital or otherwise -- is notoriously difficult, given the Hermit Kingdom's nearly airtight information controls. Lumen's findings on North Korean jailbreaking are based on interviews with just two defectors from the country. But Williams says the two escapees both independently described hacking their phones and those of other North Koreans, roughly corroborating each others' telling. Other North Korea -- focused researchers who have interviewed defectors say they've heard similar stories. Both jailbreakers interviewed by Lumen and Williams said they hacked their phones -- government-approved, Chinese-made, midrange Android phones known as the Pyongyang 2423 and 2413 -- primarily so that they could use the devices to watch foreign media and install apps that weren't approved by the government. Their hacking was designed to circumvent a government-created version of Android on those phones, which has for years included a certificate system that requires any file downloaded to the device to be "signed" with a cryptographic signature from government authorities, or else it's immediately and automatically deleted. Both jailbreakers say they were able to remove that certificate authentication scheme from phones, allowing them to install forbidden apps, such as games, as well as foreign media like South Korean films, TV shows, and ebooks that North Koreans have sought to access for decades despite draconian government bans.

In another Orwellian measure, Pyongyang phones' government-created operating system takes screenshots of the device at random intervals, the two defectors say -- a surveillance feature designed to instill a sense that the user is always being monitored. The images from those screenshots are then kept in an inaccessible portion of the phone's storage, where they can't be viewed or deleted. Jailbreaking the phones also allowed the two defectors to access and wipe those surveillance screenshots, they say. The two hackers told Lumen they used their jailbreaking skills to remove restrictions from friends' phones, as well. They said they also knew of people who would jailbreak phones as a commercial service, though often for purposes that had less to do with information freedom than more mundane motives. Some users wanted to install a certain screensaver on their phone, for instance, or wipe the phone's surveillance screenshots merely to free up storage before selling the phone secondhand.
As for how the jailbreaking was done, the report says both jailbreakers "described attaching phones to a Windows PC via a USB cable to install a jailbreaking tool."

"One mentioned that the Pyongyang 2423's software included a vulnerability that allowed programs to be installed in a hidden directory. The hacker says they exploited that quirk to install a jailbreaking program they'd downloaded while working abroad in China and then smuggled back into North Korea." The other hacker might've obtained his jailbreaking tool in a computer science group at Pyongyang's elite Kim Il Sung University where he attended.

Microsoft Fixes Point of Sale Bug That Delayed Windows 11 Startup For 40 Minutes (theregister.com) 46

"The Register reports Microsoft fixed a Point of Sale bug that delayed Windows 11 startup for 40 minutes," writes Slashdot reader ellithligraw. "So much for the express lane at check-out." From the report: A fresh Windows 11 patch slipped out overnight as an optional update, but contains an impressively long list of fixes for Microsoft's flagship operating system. One bug addressed in KB5012643 could leave Point of Sale terminals hanging for up to 40 minutes during startup. Microsoft stated, "We fixed an issue that delays OS startup by approximately 40 minutes." "Microsoft described the fixes as 'improvements' [and chose to highlight the fact that temperature would now be displayed on top of the weather icon on the taskbar]," added Slashdot reader ellithligraw. "[Y]eah, Windows 11 is great as a PoS."

30,000 New Users Signed Up For Mastodon After Elon Musk Bought Twitter (vice.com) 217

An anonymous reader quotes a report from Motherboard: Social media platform Mastodon, often seen as an alternative to Twitter, gained nearly 30,000 new users on the day that Elon Musk bought Twitter. On Tuesday a Mastodon domain became unresponsive. Eugen Rochko, Mastodon's CEO, later told Motherboard in an email that there were performance issues. "I'm sorry I couldn't have responded sooner," he wrote. "I was working all day on fixing performance issues on the Mastodon servers I operate due to the influx of new and returning users following Twitter's acquisition by Elon Musk." Rochko added that Mastodon has seen an increase of 41,287 active users, including both returning users and new users. When breaking that figure down by just new users, 28,391 new people have joined Mastodon in the past day, Rochko said.

Mastodon is a piece of open-source software that people can use as a base to create their own social networks. Although its appearance is similar to Twitter, it also differs from Twitter in the sense that Twitter is a single social network people sign up for. When it comes to the social network side of things, Mastodon holds more similarities with Discord, in that users have to find specific Mastodon instances to join. Those looking to create their own Mastodon instance also have to host it themselves, a step that may alienate many non-technical users.
Donald Trump's social media site, Truth Social, is based on Mastodon and was recently called out by the company for failing to provide the source code for the site built on top of it. Two weeks later, the social media site quietly acknowledged Mastodon in a dedicated section labeled "open source."

In regard to the matter, Mastodon founder Eugen Rochko said: "Compliance with our AGPLv3 license is very important to me as that is the sole basis upon which I and other developers are willing to give away years of work for free."

Twitter did confirm some fluctuations in follower counts after Musk's deal was made official, although they said they were organic in nature.

US Army May Be About To 'Waste' Up To $22 Billion On Microsoft HoloLens (theregister.com) 45

The US Army could end up wasting much as $22 billion in taxpayer cash if soldiers aren't actually interested in using, or able to use as intended, the Microsoft HoloLens headsets it said it would purchase, a government watchdog has warned. The Register reports: In 2018, the American military splashed $480 million on 100,000 prototype augmented-reality goggles from Redmond to see how they could help soldiers train for and fight in combat. The Integrated Visual Augmentation System (IVAS) project was expanded when the Army decided it wanted the Windows giant to make custom, battle-ready AR headsets in a ten-year deal worth up to $22 billion. The project was delayed and is reportedly scheduled to roll out some time this year. But the US Dept of Defense's Office of the Inspector General (OIG) cast some doubt on whether it was worth it at all.

"Procuring IVAS without attaining user acceptance could result in wasting up to $21.88 billion in taxpayer funds to field a system that soldiers may not want to use or use as intended," the Pentagon oversight body wrote in an audit [PDF] report this month. In other words, the Army hasn't yet fully determined if or how service members will find these HoloLens headsets valuable in the field. Although the heavily redacted report did not reveal soldiers' responses to the prototype testing, it said feedback from surveys showed "both positive and negative user acceptance." The Army plans to purchase 121,500 IVAS units from Microsoft while admitting that "if soldiers do not love IVAS and do not find it greatly enhances accomplishing the mission, then soldiers will not use it," the report disclosed.

Tech Giants Duped Into Giving Up Data Used to Sexually Extort Minors (bloomberg.com) 34

Major technology companies have been duped into providing sensitive personal information about their customers in response to fraudulent legal requests, and the data has been used to harass and even sexually extort minors, according to four federal law enforcement officials and two industry investigators. Bloomberg: The companies that have complied with the bogus requests include Meta, Apple, Alphabet's Google, Snap, Twitter and Discord, according to three of the people. All of the people requested anonymity to speak frankly about the devious new brand of online crime that involves underage victims. The fraudulently obtained data has been used to target specific women and minors, and in some cases to pressure them into creating and sharing sexually explicit material and to retaliate against them if they refuse, according to the six people.

The tactic is considered by law enforcement and other investigators to be the newest criminal tool to obtain personally identifiable information that can be used not only for financial gain but to extort and harass innocent victims. It is particularly unsettling since the attackers are successfully impersonating law enforcement officers. The tactic is impossible for victims to protect against, as the best way to avoid it would be to not have an account on the targeted service, according to the people. It's not clear how often the fraudulent data requests have been used to sexually extort minors. Law enforcement and the technology companies are still trying to assess the scope of the problem.

Ordinary Copper Telephone Wire Could Carry Gigabit Broadband Speeds (newscientist.com) 129

Fibre-optic cable is being laid across the globe at great expense to speed up people's internet connections, but researchers claim that the copper telephone wire already in use across the country can achieve data rates three times higher than currently seen at a fraction of the price, at least over short distances. New Scientist: Their technique to boost speeds may help to ease the transition to nationwide fibre optic, and may also be of use in countries that use similar twisted-pair copper wire. Ergin Dinc at the University of Cambridge and his colleagues say that twisted pairs of copper wire, of the type used for decades as telephone lines and now repurposed for broadband internet, can support a frequency fives times higher than is currently used, which would dramatically improve data transmission rates. Above that limit, the researchers found that the wire essentially acts as an aerial and transforms any signal sent along it into radio waves that dissipate before reaching their destination. "These cables are actually very old, invented by Alexander Graham Bell, and since then no one has looked into the theoretical limits," says Dinc. He and his colleagues say that their findings may allow houses near fibre-optic cables to achieve higher speeds than they currently enjoy without the expense of running fibre all the way to their home. Fibre-optic cables carry groups of photons to represent data, and huge numbers of these groups can be sent along the line one after another without waiting for the first to arrive. Fibre connections in use today typically operate at 1 gigabit per second, but theoretical speeds could be many thousands of times higher.

Google Launches Media CDN To Compete on Content Delivery (techcrunch.com) 10

This week at the 2022 NAB Show Streaming Summit, Google launched in general availability Media CDN, a platform for delivering content using the same infrastructure that powers YouTube. From a report: With a presence in over 1,300 cities across 200 countries, Google says that Media CDN is designed to -- in the company's words -- "automate all facets" of "serving content [close to users]." The pandemic led to an explosion in demand for streaming content as business closures and shelter-in-place orders forced folks to stay home.

Media CDN, which joins Google's CDN portfolio for web and API acceleration, is by no stretch of the imagination the first of its kind. There's plenty of CDNs optimized to serve media. But Google touts ostensibly unique benefits like delivery protocols tailored to individual users and network conditions and "industry-leading" offload rates. "With multiple tiers of caching, we minimize calls to origin -- even for infrequently accessed content," Google VP Shailesh Shukla wrote in a blog post yesterday. "This alleviates performance or capacity stress in the content origin and saves costs." Media CDN also features tools for ad insertion, allowing customers to dynamically inject video content with ads. Moreover, the service is "built with AI/ML" to power interactive experiences, Google says, like real-time stats during sporting events and purchase links embedded in virtual billboards.

Sony is Building a Game Preservation Team (engadget.com) 9

When Sony's expanded PlayStation Plus service starts rolling out next month, it will fold in PlayStation Now, which offers access to hundreds of games from older console generations. Now, it seems the company is getting even more serious about game preservation. From a report: According to Twitter and LinkedIn posts spotted by Video Games Chronicle, Sony has hired at least one engineer (Garrett Fredley, a former build engineer for mobile developer Kabam) to work on a new preservation team. "Today is my first day as a Senior Build Engineer at @PlayStation, working as one of their initial hires for the newly created Preservation team! Game Preservation was my first career passion, so I'm ecstatic that I get to go back to those roots," Fredley wrote. "Let's go and ensure our industry's history isn't forgotten!" [...] Sony historically hasn't done an incredible job with preserving games. Aside from the original PS3 models being able to run many PS1 and PS2 games, backward compatibility seemed like an afterthought until the PS5, which supports all but a few PS4 titles.

Apple Launches Do-It-Yourself Repairs For iPhone 13, iPhone 12 and iPhone SE, But There's a Catch (cnet.com) 58

Apple on Wednesday followed through on its plans to begin publicly releasing repair manuals for some of its products, in addition to selling parts and tools online. The goal, the company said, is to allow iPhone owners an alternative way to repair their devices. From a report: The tech giant's new program, called Self Service Repair, is starting out for US customers with Apple's iPhone 13 line of smartphones, the iPhone 12 and new iPhone SE. Apple said it designed the program to offer adventurous and capable people access to the same parts, tools and instructions it gives to its own certified technicians and partner repair shops, hopefully making it easier for people to repair devices instead of resorting to buying a new one. "We believe we have a responsibility to customers and the environment to offer convenient access to safe, reliable, and secure repairs to help customers get the most out of their devices," the company wrote in a document published Wednesday that outlines its plans. "As the doors open on this new venue, we're underwhelmed, and settling back into our usual skepticism," iFixit posted on Wednesday. The firm adds: The biggest problem? Apple is doubling down on their parts pairing strategy, enabling only very limited, serial number-authorized repairs. You cannot purchase key parts without a serial number or IMEI. If you use an aftermarket part, there's an "unable to verify" warning waiting for you. This strategy hamstrings third-party repair with feature loss and scare tactics and could dramatically limit options for recyclers and refurbishers, short-circuiting the circular economy. As of today, you can buy an official Apple iPhone 12 screen and install it yourself, on your own device, with no fuss. Until now, DIY repairs relied on keeping the Face ID speaker and sensor assembly intact, then very carefully moving it to your new screen, and finally ignoring some gentle warnings. If your assembly was damaged or defective, you were out of luck. The new program will solve that problem -- assuming you've bought an official Apple part.

Twitter Is Protecting Its Source Code From Disgruntled Employees, Reports Say (techcrunch.com) 273

An anonymous reader quotes a report from TechCrunch: Twitter locked down its source code to prevent unauthorized changes, sources familiar with the matter told Bloomberg. The reports say that this change was made to prevent employees from "going rogue" and sabotaging the platform after Elon Musk's $44 billion purchase of the company. Currently, a vice president must approve any changes. After the company announced it would accept Musk's offer to buy the publicly traded platform, it wasn't immediately clear to Twitter's 7,000 employees how their day-to-day would change. Even after a company all-hands, where CEO Parag Agrawal reassured the team that no layoffs were planned "at this time," employees were still left with questions about how they would fare in Musk's takeover. [...] For now, Musk's takeover bid for Twitter remains subject to shareholder and regulatory approval. But if it goes through as expected, we may witness major personnel shifts, resignations and more. A similar shake-up took place when Twitter was listed on the New York Stock Exchange for the first time. By the time the company went public, there were already 90 startups being built by former Twitter employees.

Facebook Doesn't Know What It Does With Your Data, Or Where It Goes (vice.com) 59

em1ly shares a report from Motherboard: Facebook is facing what it describes internally as a "tsunami" of privacy regulations all over the world, which will force the company to dramatically change how it deals with users' personal data. And the "fundamental" problem, the company admits, is that Facebook has no idea where all of its user data goes, or what it's doing with it, according to a leaked internal document obtained by Motherboard. "We've built systems with open borders. The result of these open systems and open culture is well described with an analogy: Imagine you hold a bottle of ink in your hand. This bottle of ink is a mixture of all kinds of user data (3PD, 1PD, SCD, Europe, etc.) You pour that ink into a lake of water (our open data systems; our open culture) ... and it flows ... everywhere," the document read. "How do you put that ink back in the bottle? How do you organize it again, such that it only flows to the allowed places in the lake?" (3PD means third-party data; 1PD means first-party data; SCD means sensitive categories data.)

The document was written last year by Facebook privacy engineers on the Ad and Business Product team, whose mission is "to make meaningful connections between people and businesses," and which "sits at the center of our monetization strategy and is the engine that powers Facebook's growth," according to a recent job listing that describes the team. This is the team that is tasked with building and maintaining Facebook's sprawling ads system, the core of the company's business. And in this document, the team is both sounding an alarm, and making a call to change how Facebook deals with users' data to prevent the company from running into trouble with regulators in Europe, the US, India, and other countries that are pushing for more stringent privacy constraints on social media companies. "We do not have an adequate level of control and explainability over how our systems use data, and thus we can't confidently make controlled policy changes or external commitments such as 'we will not use X data for Y purpose.' And yet, this is exactly what regulators expect us to do, increasing our risk of mistakes and misrepresentation," the document read. In other words, even Facebook's own engineers admit that they are struggling to make sense and keep track of where user data goes once it's inside Facebook's systems, according to the document. This problem inside Facebook is known as "data lineage."

NASA's Space Telecoms Network May Soon Be Outsourced (space.com) 23

vm shares a report from Space.com: SpaceX is among companies that might replace services of NASA's aging space telecoms constellation that has kept the International Space Station connected to Earth for decades. For years, NASA's Tracking and Data Relay Satellite (TDRS) constellation has served as the main link between the International Space Station and Earth, providing astronauts with constant connection to ground control as well as the ability to engage with the public and stay in touch with their loved ones. The American space agency, however, plans to retire the six aging satellites in the next decade and hand over their task to commercial companies. This month, the agency announced partnerships with six commercial satellite operators including SpaceX, U.K. company Inmarsat, American Viasat and Switzerland-based SES, to demonstrate how they could take care of NASA's space communication needs in the future. "We don't plan to launch any new TDRS satellites in the future," Eli Naffah, the manager of NASA's Commercial Services Project, who oversees the partnership with the commercial companies, told Space.com. "The plan is to allow the constellation to basically [reach the end of its life]. At some point later in this decade, we are going to have some diminished capability and the plan is for the [commercial companies] to come up with a different way of providing communication services to our missions."

"Back in the 1980s, when we developed TDRS, there really wasn't an ability on the commercial side to be able to provide this service," Naffah said. "But since then, the industry has far outpaced NASA's investment in this area. There's a lot of infrastructure, both on the ground and in orbit that is capable of providing these types of services to a spacecraft. [...] Hopefully, we can achieve some cost efficiencies in buying commercial services, get out of the business of operating networks, and really put more focus on science and exploration." According to Naffah, NASA will invest $278 million into the project over the next five years, with the agency's industry partners contributing a total of about $1.5 billion.

Apple's Grip On iOS Browser Engines Disallowed Under Latest Draft EU Rules (theregister.com) 74

Europe's Digital Markets Act -- near-finalized legislation to tame the internet's gatekeepers -- contains language squarely aimed at ending Apple's iOS browser restrictions. The Register reports: The Register has received a copy of unpublished changes in the proposed act, and among the various adjustments to the draft agreement is the explicit recognition of "web browser engines" as a service that should be protected from anti-competitive gatekeeper-imposed limitations. Apple requires that competing mobile browsers distributed through the iOS App Store use its own WebKit rendering engine, which is the basis of its Safari browser. The result is that Chrome, Edge, and Firefox on iOS are all, more or less, Safari.

That requirement has been a sore spot for years among rivals like Google, Mozilla, and Microsoft. They could not compete on iOS through product differentiation because their mobile browsers had to rely on WebKit rather than their own competing engines. And Apple's browser engine requirement has vexed web developers, who have been limited to using only the web APIs implemented in WebKit for their web apps. Many believe this barrier serves to steer developers toward native iOS app development, which Apple controls.

The extent to which Apple profits from the status quo has prompted regulatory scrutiny in Europe, the UK, the US, and elsewhere. [...] Now those efforts have been translated into the text of the DMA, which, alongside the Digital Services Act (DSA), defines how large technology gatekeepers will be governed in Europe. [...] In short, when the DMA takes effect in 2024, it appears that Apple will be required to allow browser competition on iOS devices.
"The potential for a capable web has been all but extinguished on mobile because Apple has successfully prevented it until now," said Alex Russell, partner program manager on Microsoft Edge who worked previously as Google Chrome's first web standards tech lead. "Businesses and services will be able to avoid building 'apps' entirely when enough users have capable browsers."

"There's a long road between here and there," he added. "Apple has spent enormous amounts to lobby on this, and they aren't stupid. Everyone should expect them to continue to play games along the lines of what they tried in Denmark and South Korea."

Virtual Events Startup Hopin Struggles as Real Gatherings Return (ft.com) 16

British group gained $7.8bn valuation in pandemic, but lay-offs and slump in secondary market trades have followed. From a report: In November 2020, with the pandemic in full force, British virtual events start-up Hopin declared that a new era of digital gatherings had begun. Virtual events were "here to stay," said founder Johnny Boufarhat, as he bragged that there were "more than 15,000 monthly events" available on Hopin's "Explore" platform. Today, there are fewer than 500 listed. Boufarhat's vision made Hopin a pandemic sensation and Europe's fastest growing start-up ever. Launched in 2019, his company rocketed to fame after Covid hit with a conferencing product that seemed tailor-made for lockdowns. The 27-year-old raised more than a billion dollars for Hopin in little over a year, reaching a $7.8bn private market valuation that made him Britain's youngest self-made billionaire on paper.

As top-tier venture capital firms like IVP, Andreessen Horowitz and Tiger Global clamoured to invest, Boufarhat sold $195mn worth of his own shares, according to a Financial Times analysis. With Covid beginning to recede and publicly traded technology stocks being dumped by investors, Boufarhat now faces a moment of truth as he tries to build a sustainable business that lives up to the lofty expectations it set during the pandemic. "The landscape will look very different going forward. People can now meet," noted one events industry executive. They dismissed the pandemic-driven online events boom as "a bit of an artificial bubble."

Chess.com Banned By Russia (chess.com) 53

Chess.com, writes in a blog post: Yesterday, Chess.com was banned by the Russian government agency Roscomnadzor, the "Federal Service for Supervision of Communications, Information Technology and Mass Media." Roscomnadzor is responsible for censorship within Russia, a busy occupation these days. Since the start of Russia's war against Ukraine on February 24th, Roscomnadzor has banned hundreds of sites including Facebook, Twitter, Instagram, Google News, BBC News, NPR, and Amnesty International. According to Roscomnadzor, their goal is to block two webpages: "On The Invasion of Ukraine" which outlines our policy and actions regarding the war on Ukraine and addresses FAQ and "Ukrainian Chess Players In Times Of War" which is a piece interviewing Ukrainian chess players on their circumstances and views during the early days of the war. Since Chess.com uses secure https webpages, Roscomnadzor is unable to ban these single pages and has banned the entire Chess.com site. Our members report that Chess.com's apps are unaffected. We happily encourage our Russian members to continue accessing our site using our apps or any of the many outstanding VPN services that are so essential in Russia.

Concerns Raised Over The 'New' NTFS Linux Driver That Merged Last Year (phoronix.com) 90

UnknowingFool writes: In 2020, Paragon Software announced they wanted to upstream their previously proprietary NTFS driver into Linux. After a year of review, the NTFS3 driver was added to the Linux 5.15 kernel. While Paragon pledged to maintain their driver, there have been no major updates to the driver despite a growing list of patches that have submitted. Developer Kari Argillander has raised his concerns on the mailing list that the driver is orphaned, and that the Paragon maintainer has not responded to any messages about fixes. An offer to co-maintain the driver has also been met with "radio silence".

Chip Startups Using Light Instead of Wires Gaining Speed and Investments (reuters.com) 26

Computers using light rather than electric currents for processing, only years ago seen as research projects, are gaining traction and startups that have solved the engineering challenge of using photons in chips are getting big funding. From a report: In the latest example, Ayar Labs, a startup developing this technology called silicon photonics, said on Tuesday it had raised $130 million from investors including chip giant Nvidia. While the transistor-based silicon chip has increased computing power exponentially over past decades as transistors have reached the width of several atoms, shrinking them further is challenging. Not only is it hard to make something so miniscule, but as they get smaller, signals can bleed between them.

So, Moore's law, which said every two years the density of the transistors on a chip would double and bring down costs, is slowing, pushing the industry to seek new solutions to handle increasingly heavy artificial intelligence computing needs. According to data firm PitchBook, last year silicon photonics startups raised over $750 million, doubling from 2020. In 2016 that was about $18 million. The challenge is that many large machine-learning algorithms can use hundreds or thousands of chips for computing, and there is a bottleneck on the speed of data transmission between chips or servers using current electrical methods.

Payment Startup Bolt Sued by Its Most Prominent Customer (bloomberg.com) 9

Bolt, the payments startup known for its founder's inflammatory Twitter threads claiming Silicon Valley is run by "mob bosses," is being sued by its most prominent customer. From a report: The complaint by Authentic Brands Group alleges that Bolt not only failed to deliver promised technology but that during Bolt's integration with Forever 21, the clothier lost out on more than $150 million in online sales. The complaint also states that Bolt raised funding at increasingly high valuations by "consistently overstating" the nature of its integration with ABG's brands to suggest it had more customers than it did and to convince investors to bankroll additional growth for the startup. Because Bolt's business relies on having a large network of consumers, the allegations create major new uncertainty for the controversial payments startup, which investors most recently valued at $11 billion. In a filing, Bolt responded to the complaint saying that ABG's claims are without merit, and are "a transparent attempt" to renegotiate the terms of the companies' agreements.
