Google Files a Lawsuit That Could Kick Tinder Out of the Play Store

Google has counter-sued Match seeking monetary damages and a judgement that would let it kick Tinder and the group’s other dating apps out of the Play Store, Bloomberg has reported. Engadget reports: Earlier this year, Match sued Google alleging antitrust violations over a decision requiring all Android developers to process “digital goods and services” payments through the Play Store billing system. Following the initial lawsuit in May, Google and Match reached a temporary agreement allowing Match to remain on the Play Store and use its own payments system. Google also agreed to make a “good faith” effort to address Match’s billing concerns. Match, in turn, was to make an effort to offer Google’s billing system as an alternative.

However, Google parent Alphabet claims that Match Group now wants to avoid paying “nothing at all” to Google, including its 15 to 30 percent Play Store fees, according to a court filing. “Match Group never intended to comply with the contractual terms to which it agreed… it would also place Match Group in an advantaged position relative to other app developers,” the document states. Match group said that Google’s Play Store policies violate federal and state laws. “Google doesn’t want anyone else to sue them so their counterclaims are designed as a warning shot,” Match told Bloomberg in a statement. “We are confident that our suit, alongside other developers, the US Department of Justice and 37 state attorneys general making similar claims, will be resolved in our favor early next year.”

Lenovo Patches UEFI Code Execution Vulnerability Affecting More Than 70 Laptop Models

Lenovo has released a security advisory to inform customers that more than 70 of its laptops are affected by a UEFI/BIOS vulnerability that can lead to arbitrary code execution. SecurityWeek reports: Researchers at cybersecurity firm ESET discovered a total of three buffer overflow vulnerabilities that can allow an attacker with local privileges to affected Lenovo devices to execute arbitrary code. However, Lenovo says only one of the vulnerabilities (CVE-2022-1892) impacts all devices, while the other two impact only a handful of laptops. “The vulnerabilities can be exploited to achieve arbitrary code execution in the early phases of the platform boot, possibly allowing the attackers to hijack the OS execution flow and disable some important security features,” ESET explained. “These vulnerabilities were caused by insufficient validation of DataSize parameter passed to the UEFI Runtime Services function GetVariable. An attacker could create a specially crafted NVRAM variable, causing buffer overflow of the Data buffer in the second GetVariable call,” it added.

Lenovo has also informed customers about Retbleed, a new speculative execution attack impacting devices with Intel and AMD processors. The company has also issued an advisory for a couple of vulnerabilities affecting many products that use the XClarity Controller server management engine. These flaws can allow authenticated users to cause a DoS condition or make unauthorized connections to internal services.

Weed Killer Glyphosate Found In Most Americans’ Urine

An anonymous reader quotes a report from U.S. News & World Report: More than 80% of Americans have a widely used herbicide lurking in their urine, a new government study suggests. The chemical, known as glyphosate, is “probably carcinogenic to humans,” the World Health Organization’s International Agency for Research on Cancer has said. Glyphosate is the active ingredient in Roundup, a well-known weed killer. The U.S. National Nutrition Examination Survey found the herbicide in 1,885 of 2,310 urine samples that were representative of the U.S. population. Nearly a third of the samples came from children ages 6 to 18.

Traces of the herbicide have previously been found in kids’ cereals, baby formula, organic beer and wine, hummus and chickpeas. In 2020, the EPA determined that the chemical was not a serious health risk and “not likely” to cause cancer in humans. However, a federal appeals court ordered the EPA to reexamine those findings last month, CBS News reported. In 2019, a second U.S. jury ruled Bayer’s Roundup weed killer was the cause of a man’s cancer. It was only the second of some 11,200 Roundup lawsuits to go to trial in the United States. Another California man was awarded $78 million (originally $289 million) in the first lawsuit alleging a glyphosate link to cancer.

A study published around the same time as those rulings found that glyphosate “destroys specialized gut bacteria in bees, leaving them more susceptible to infection and death from harmful bacteria.”

TikTok Hits Pause On Its Most Controversial Privacy Update Yet

Early last month, TikTok users across Europe were told that, starting July 13th, the platform would begin using their on-app data to serve up targeted ads, even if those users didn’t consent to the practice. Now, less than a day before that change would have rolled out European Union-wide, it looks like the company’s reconsidering things a bit. Gizmodo reports: A company spokesperson told TechCrunch on Tuesday that TikTok is “pausing” the update while it “engage[s] on the questions from stakeholders,” about the way it handles personalized ads. And needless to say, there are quite a lot of questions about that right now — from data protection authorities in the EU, from lawmakers in the US, and from privacy experts pretty much everywhere.

For context: until this point, European users that opened the TikTok app needed to offer express consent to let the company use their data for targeted ads. This update planned to do away with the need for that pesky consent by on a legal basis known as “legitimate interest” to target those ads instead. In a nutshell, the “legitimate interest” clause would let TikTok process people’s data, consent-free, if it was for a purpose that TikTok deemed reasonable. This means the company could say, for example, that because targeted ads bring in more money than their un-targeted equivalent, it would be reasonable to serve all users — consenting or otherwise — targeted ads. Reasonable, right?

New Working Speculative Execution Attack Sends Intel and AMD Scrambling

Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers scrambling once again to contain what is proving to be a stubbornly persistent vulnerability. Ars Technica reports: Researchers from ETH Zurich have named their attack Retbleed because it exploits a software defense known as retpoline, which was introduced in 2018 to mitigate the harmful effects of speculative execution attacks. Speculative execution attacks, also known as Spectre, exploit the fact that when modern CPUs encounter a direct or indirect instruction branch, they predict the address for the next instruction they’re about to receive and automatically execute it before the prediction is confirmed. Spectre works by tricking the CPU into executing an instruction that accesses sensitive data in memory that would normally be off-limits to a low-privileged application. Retbleed then extracts the data after the operation is canceled. […] The ETH Zurich researchers have conclusively shown that retpoline is insufficient for preventing speculative execution attacks. Their Retbleed proof-of-concept works against Intel CPUs with the Kaby Lake and Coffee Lake microarchitectures and AMD Zen 1, Zen 1+, and Zen 2 microarchitectures.

In response to the research, both Intel and AMD advised customers to adopt new mitigations that the researchers said will add as much as 28 percent more overhead to operations. […] Both Intel and AMD have responded with advisories. Intel has confirmed that the vulnerability exists on Skylake-generation processors that don’t have a protection known as enhanced Indirect Branch Restricted Speculation (eIBRS) in place. “Intel has worked with the Linux community and VMM vendors to provide customers with software mitigation guidance which should be available on or around today’s public disclosure date,” Intel wrote in a blog post. “Note that Windows systems are not affected given that these systems use Indirect Branch Restricted Speculation (IBRS) by default which is also the mitigation being made available to Linux users. Intel is not aware of this issue being exploited outside of a controlled lab environment.” AMD, meanwhile, has also published guidance. “As part of its ongoing work to identify and respond to new potential security vulnerabilities, AMD is recommending software suppliers consider taking additional steps to help guard against Spectre-like attacks,” a spokesman wrote in an email. The company has also published a whitepaper.

[Research Kaveh Razavi added:] “Retbleed is more than just a retpoline bypass on Intel, specially on AMD machines. AMD is in fact going to release a white paper introducing Branch Type Confusion based on Retbleed. Essentially, Retbleed is making AMD CPUs confuse return instructions with indirect branches. This makes exploitation of returns very trivial on AMD CPUs.” The mitigations will come at a cost that the researchers measured to be between 12 percent and 28 percent more computational overhead. Organizations that rely on affected CPUs should carefully read the publications from the researchers, Intel, and AMD and be sure to follow the mitigation guidance.

Edits To a Cholesterol Gene Could Stop the Biggest Killer On Earth

A volunteer in New Zealand has become the first person to undergo DNA editing in order to lower their blood cholesterol, a step that may foreshadow wide use of the technology to prevent heart attacks. MIT Technology Review reports: The experiment, part of a clinical trial by the US biotechnology company Verve Therapeutics, involved injecting a version of the gene-editing tool CRISPR in order to modify a single letter of DNA in the patient’s liver cells. According to the company, that tiny edit should be enough to permanently lower a person’s levels of “bad” LDL cholesterol, the fatty molecule that causes arteries to clog and harden with time. The patient in New Zealand had an inherited risk for extra-high cholesterol and was already suffering from heart disease. However, the company believes the same technique could eventually be used on millions of people in order to prevent cardiovascular disease.

In New Zealand, where Verve’s clinical trial is taking place, doctors will give the gene treatment to 40 people who have an inherited form of high cholesterol known as familial hypercholesterolemia, or FH. People with FH can have cholesterol readings twice the average, even as children. Many learn they have a problem only when they get hit with a heart attack, often at a young age. The study also marks an early use of base editing, a novel adaptation of CRISPR that was first developed in 2016. Unlike traditional CRISPR, which cuts a gene, base editing substitutes a single letter of DNA for another.

The gene Verve is editing is called PCSK9. It has a big role in maintaining LDL levels and the company says its treatment will turn the gene off by introducing a one-letter misspelling. […] One reason Verve’s base-editing technique is moving fast is that the technology is substantially similar to mRNA vaccines for covid-19. Just like the vaccines, the treatment consists of genetic instructions wrapped in a nanoparticle, which ferries everything into a cell. While the vaccine instructs cells to make a component of the SARS-CoV-2 virus, the particles in Verve’s treatment carry RNA directions for a cell to assemble and aim a base-editing protein, which then modifies that cell’s copy of PCSK9, introducing the tiny mistake. In experiments on monkeys, Verve found that the treatment lowered bad cholesterol by 60%. The effect has lasted more than a year in the animals and could well be permanent. The report notes that the human experiment does carry some risk. “Nanoparticles are somewhat toxic, and there have been reports of side effects, like muscle pain, in people taking other drugs to lower PCSK9,” reports MIT Technology Review. “And whereas treatment with ordinary drugs can be discontinued if problems come up, there’s as yet no plan to undo gene editing once it’s performed.”

Xbox Series X Can Run Windows 98, Along With Classic PC Games of The Era

Alex Battaglia from the YouTube channel “Digital Foundry” was able to use the “RetroArch” software emulator to run Windows 98 on the Xbox Series X, along with several PC games of the era. “Technically, you’re supposed to be an Xbox developer to access this, and you will need to sign up to the paid Microsoft Partner program and turn on ‘Developer Mode’ for your system to activate it,” notes Pure Xbox. “In DF’s case, rather than directly playing emulated games through RetroArch, they used the program to install Windows 98 software.” From the report: Beyond the novelty of actually booting up Win98 on a modern console the channel then decided to test out some games, running through the older version of Windows. Playthroughs of Turok, Command & Conquer, Quake 2 and more were all pretty successful, although the act of loading them onto the software requires a bit of messing about (you have to create ISO files and transfer them over — sadly, Xbox’s disc drive can’t read the original discs). Of course, this wouldn’t be a Digital Foundry video without some performance comparisons, so the team did just that. The video compares hardware of the era with Xbox Series X’s emulation, and while the console often lags behind due to the fact that it’s literally emulating an entire version of Windows, and then a game on top of that, it fares pretty well overall. You can watch Digital Foundry’s video here.

GameStop Launches NFT Marketplace

GameStop on Monday announced the long-awaited debut of its online marketplace for nonfungible tokens, or NFTs, in a bid to reinvent its business and cash in on consumer adoption of cryptocurrencies and blockchain technology. CNBC reports: The platform, which is now open to the public for beta testing, allows users to connect their own digital asset wallets, including the recently launched GameStop Wallet, the company said in a press release. They will then be able to buy, sell and trade NFTs of virtual goods. Over time, the marketplace will expand to offer other features such as Web3 gaming, GameStop said. “Currently, the marketplace plays host to an array of artwork projects that run on the Ethereum mainnet as well as Loopring, a layer-2 scaling solution,” adds Decrypt. “GameStop previously announced a partnership to use the Immutable X layer-2 scaling network, but the marketplace notes that Immutable X support is ‘coming soon.'”

“GameStop and Immutable X launched a $100 million token grant fund to bring game developers onto the marketplace. A press release notes that gaming NFTs will be added in the future.”

Physicists Discover a ‘Family’ of Robust, Superconducting Graphene Structures

In 2018, MIT researchers found that if two graphene layers are stacked at a very specific “magic” angle, the twisted bilayer structure could exhibit robust superconductivity, a widely sought material state in which an electrical current can flow through with zero energy loss. Now the team reports that […] four and five graphene layers can be twisted and stacked at new magic angles to elicit robust superconductivity at low temperatures. Phys.Org reports: This latest discovery, published this week in Nature Materials, establishes the various twisted and stacked configurations of graphene as the first known “family” of multilayer magic-angle superconductors. The team also identified similarities and differences between graphene family members. The findings could serve as a blueprint for designing practical, room-temperature superconductors. If the properties among family members could be replicated in other, naturally conductive materials, they could be harnessed, for instance, to deliver electricity without dissipation or build magnetically levitating trains that run without friction.

In the current study, the team looked to level up the number of graphene layers. They fabricated two new structures, made from four and five graphene layers, respectively. Each structure is stacked alternately, similar to the shifted cheese sandwich of twisted trilayer graphene. The team kept the structures in a refrigerator below 1 kelvin (about -273 degrees Celsius), ran electrical current through each structure, and measured the output under various conditions, similar to tests for their bilayer and trilayer systems. Overall, they found that both four- and five-layer twisted graphene also exhibit robust superconductivity and a flat band. The structures also shared other similarities with their three-layer counterpart, such as their response under a magnetic field of varying strength, angle, and orientation.

These experiments showed that twisted graphene structures could be considered a new family, or class of common superconducting materials. The experiments also suggested there may be a black sheep in the family: The original twisted bilayer structure, while sharing key properties, also showed subtle differences from its siblings. For instance, the group’s previous experiments showed the structure’s superconductivity broke down under lower magnetic fields and was more uneven as the field rotated, compared to its multilayer siblings. The team carried out simulations of each structure type, seeking an explanation for the differences between family members. They concluded that the fact that twisted bilayer graphene’s superconductivity dies out under certain magnetic conditions is simply because all of its physical layers exist in a “nonmirrored” form within the structure. In other words, there are no two layers in the structure that are mirror opposites of each other, whereas graphene’s multilayer siblings exhibit some sort of mirror symmetry. These findings suggest that the mechanism driving electrons to flow in a robust superconductive state is the same across the twisted graphene family.

Is Amazon’s AWS Quietly Getting Better at Contributing to Open Source?

“If I want AWS to ignore me completely all I have to do is open a pull request against one of their repositories,” quipped cloud economist Corey Quinn in April, while also complaining that the real problem is “how they consistently and in my opinion incorrectly try to shape a narrative where they’re contributing to the open source ecosystem at a level that’s on par with their big tech company peers.”

But on Friday tech columnist Matt Asay argued that AWS is quietly getting better at open source. “Agreed,” tweeted tech journalist Steven J. Vaughan-Nichols in response, commending “Good open source people, good open-source work.” (And Vaughan-Nichols later retweeted an AWS principle software engineer’s announcement that “Over at Amazon Linux we are hiring, and also trying to lead and better serve customers by being more involved in upstream communities.”) Mark Atwood, principle engineer for open source at Amazon, also joined Asay’s thread, tweeting “I’m glad that people are noticing. Me and my team have been doing heavy work for years to get to this point. Generally we don’t want to sit at the head of the table, but we are seeing the value of sitting at the table.”

Asay himself was AWS’s head of developer marketing/Open Source strategy for two years, leaving in August of 2021. But Friday Asay’s article noted a recent tweet where AWS engineer Divij Vaidya announced he’d suddenly become one of the top 10 contributors to Apache Kafka after three months as the founding engineer for AWS’s Apache Kafka open source team. (Vaida added “We are hiring for a globally distributed fully remote team to work on open source Apache Kafka! Join us.”)
Asay writes:
Apache Kafka is just the latest example of this…. This is exactly what critics have been saying AWS doesn’t do. And, for years, they were mostly correct.

AWS was, and is, far more concerned with taking care of customers than being popular with open-source audiences. So, the company has focused on being “the best place for customers to build and run open-source software in the cloud.” Historically, that tended to not involve or require contributing to the open-source projects it kept building managed services around. Many felt that was a mistake — that a company so dependent on open source for its business was putting its supply chain at risk by not sustaining the projects upon which it depended…

PostgreSQL contributor (and sometime AWS open-source critic) Paul Ramsey has noticed. As he told me recently, it “[f]eels like a switch flipped at AWS a year or two ago. The strategic value of being a real stakeholder in the software they spin is now recognized as being worth the dollars spent to make it happen….” What seems to be happening at AWS, if quietly and usually behind the scenes, is a shift toward AWS service teams taking greater ownership in the open-source projects they operationalize for customers. This allows them to more effectively deliver results because they can help shape the roadmap for customers, and it ensures AWS customers get the full open-source experience, rather than a forked repo with patches that pile up as technical debt.

Vaidya and the Managed Service for Kafka team is an example along with Madelyn Olson, an engineer with AWS’s ElastiCache team and one of five core maintainers for Redis. And then there are the AWS employees contributing to Kubernetes, etcd and more. No, AWS is still not the primary contributor to most of these. Not yet. Google, Microsoft and Red Hat tend to top many of the charts, to Quinn’s point above. This also isn’t somehow morally wrong, as Quinn also argued: “Amazon (and any company) is there to make money, not be your friend.”
But slowly and surely, AWS product teams are discovering that a key element of obsessing over customers is taking care of the open-source projects upon which those customers depend. In other words, part of the “undifferentiated heavy lifting” that AWS takes on for customers needs to be stewardship for the open-source projects those same customers demand.

UPDATE: Reached for a comment today, Asay clarified his position on Quinn’s original complaints about AWS’s low level of open source contributions. “What I was trying to say was that while Corey’s point had been more-or-less true, it wasn’t really true anymore.”
