In a preprint posted online Thursday night, researchers at Google in collaboration with physicists at Stanford, Princeton and other universities say that they have used Google's quantum computer to demonstrate a genuine "time crystal" for the first time. From a report: A novel phase of matter that physicists have strived to realize for many years, a time crystal is an object whose parts move in a regular, repeating cycle, sustaining this constant change without burning any energy. "The consequence is amazing: You evade the second law of thermodynamics," said co-author Roderich Moessner, director of the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany. That's the law that says disorder always increases.

Time crystals are also the first objects to spontaneously break "time-translation symmetry," the usual rule that a stable object will remain the same throughout time. A time crystal is both stable and ever-changing, with special moments that come at periodic intervals in time. The time crystal is a new category of phases of matter, expanding the definition of what a phase is. All other known phases, like water or ice, are in thermal equilibrium: Their constituent atoms have settled into the state with the lowest energy permitted by the ambient temperature, and their properties don't change with time. The time crystal is the first "out-of-equilibrium" phase: It has order and perfect stability despite being in an excited and evolving state. "This is just this completely new and exciting space that we're working in now," said Vedika Khemani, a condensed matter physicist now at Stanford who co-discovered the novel phase while she was a graduate student and co-authored the new paper.

Security researchers say they have uncovered an ongoing hacking campaign carried out by suspected Russian spies who are continuing to stage attacks amid U.S. pressure on the Kremlin to curtail its alleged cyber-intrusions. From a report: The California-based cybersecurity firm RiskIQ Inc. said in a report released on Friday that it had uncovered more than 30 command and control servers -- used by cybercriminals to send orders to compromised networks or receive stolen data -- associated with the state-sponsored hacking group, which is known as APT29 or Cozy Bear. The group is using the servers to deploy malicious software named WellMess, according to RiskIQ. APT stands for "advanced persistent threat," and is a term often used to describe state-sponsored hacking groups.

In July last year, government agencies from the U.S., U.K., and Canada, said that APT29 was "almost certainly" part of the Russian intelligence services and accused it of hacking organizations involved in the development of the Covid-19 vaccine and stealing intellectual property. The same group was also allegedly involved in the 2016 hack on the Democratic National Committee and the breach of SolarWinds, which was disclosed last year, according to U.S. officials. The Russian embassy in Washington referred to an earlier statement, in which it urged journalists to stop "sweeping accusations" and said it was confident that discussions with the U.S. related to cyberspace would "improve the security of the information infrastructure of our countries."

China ordered more than two dozen technology firms to carry out internal inspections as part of a campaign to root out illegal online activity. From a report: The Ministry of Industry Information Technology on Friday told 25 of its largest internet and hardware companies including Alibaba Group Holding and Tencent Holdings to carry out internal reviews and rectify issues ranging from data security to consumer rights protections. The twin giants and 10 other firms were also asked separately on Wednesday to step up data security protections, including the export of key information, by the Internet Society of China, which was acting on behalf of MIIT.

The meetings this week come after the internet industry regulator announced on Monday it was beginning a six-month campaign to crackdown on illegal online activity. Days later, it told Tencent and 13 other corporations to address problems related to pop-ups within their ads. The crackdown is the latest move by Beijing to rein in the country's internet leaders in areas from antitrust to data security and ride-hailing. Meituan, Xiaomi and ByteDance were among firms summoned to both meetings. On Friday, the MIIT ordered the companies to address eight types of problematic behavior including pop-ups, data collection and storage as well as the blocking of external links.

An anonymous reader shares a report: Alphabet's Google asked a federal judge to order Microsoft to hand over internal documents from certain executives that Google says it needs to defend a Justice Department's monopoly lawsuit. Google said in a court filing Thursday night in Washington that Microsoft refuses to search the files of 19 executives that are relevant to Google's defense.

Microsoft is a key player in the Justice Department's lawsuit, which accuses Google of abusing its dominance in internet search. The government says Google illegally used its power in the market to thwart competitive threats from rivals like Microsoft's Bing search engine. "No third party is more central to this litigation than Microsoft," Google said in the filing. Microsoft countered in a separate filing that Google's request for documents is unreasonable and burdensome. Microsoft said it offered to collect documents from 27 individuals and that Google has proposed it provide information from an additional 28, for a total of 55.

Kekke writes: "Taiwan Semiconductor Manufacturing Co.'s new foundry will produce 2-nanometer chips," reports Gizmodo. "Construction on the plant in Hsinchu, southwest from Taiwan's capital of Taipei, is expected to start as soon as early 2022. TSMC's 3nm tech is reportedly expected to be put into production in late 2022 -- meanwhile, Intel will be rolling out 7nm chips toward the end of 2022 and into 2023." Will Intel have a genie in the bottle or a rabbit in a hat? Doesn't seem so to me. On Tuesday, Intel unveiled a comeback plan designed to help it reclaim processor manufacturing leadership within four years.

Google's updated its inappropriate content policy to ban "compensated sexual relationships" -- i.e., sugar daddy or sugar dating apps. Ryne Hager writes via Android Police: If somehow you aren't familiar with the term, a "sugar daddy" is more than a caramel candy on a stick. In the more common vernacular, a sugar daddy is a person -- usually an older man, but you could have a "sugar mommy" or maybe a gender-neutral "sugar parent?" -- that spends or gives money in what is typically a transactional relationship, often for sexual favors.

I don't judge, different people enjoy different things, and if all parties are consenting with full knowledge, I don't see how an arrangement like that really harms anyone. But, it seems Google does care, though the company is clear it's not objecting to the nature of the relationship, merely the fact that they're often sexual relationships with a perceived compensation basis, and the company has a blanket ban on sexual content -- at least partly ignoring the primary impulse for many customers behind more generalized dating apps like Tinder and Hinge, as well as many of the messages that even mainstream dating app users swap.

Microsoft has released the first beta of Windows 11, available to those enrolled in its Windows Insider Program. From a report: Until today, getting access to Windows 11 meant installing the Dev preview, which Microsoft says is for "highly technical users" as it has "rough edges." According to Microsoft, the beta release is less volatile, with builds being validated by Microsoft (though it's still probably something you'll want to install on a test machine or second partition). Of course, to install the beta you'll need a compatible computer. Figuring out if your hardware will work with the next version of Windows has been notoriously tricky to pin down, but Microsoft's article about preparing for Insider builds directs people to its system requirements page. The company has said that it will be paying close attention to how well 7th Gen Intel and AMD Zen 1 CPUs work during the testing period, so it's possible those systems could be allowed to run the beta but not the final release.

Facebook's next hardware launch will be its long-awaited Ray-Ban 'smart glasses,' CEO Mark Zuckerberg confirmed on an earnings call this week. When exactly the glasses will arrive is unclear. We least heard they were launching some time in 2021, but the pandemic has changed a lot of companies' plans, and Zuckerberg did not comment on a time frame. From a report: "Looking ahead here, the next product release will be the launch of our first smart glasses from Ray-Ban in partnership with EssilorLuxottica," said the Facebook CEO. "The glasses have their iconic form factor, and they let you do some pretty neat things."

We don't know what those "neat things" are, though Facebook has previously confirmed that the glasses will not have an integrated display and are not classified as an augmented reality device. Will they be able to make voice calls? Will they have access to a smart assistant? It's not clear. Though without an integrated display, they will presumably rely on a paired smartphone app for controls, similar to Snap Spectacles or Amazon's Echo Frames.

The White House announced Wednesday that its "once-in-a-generation investment in our infrastructure" would include a part dedicated to improving Americans' access to the internet. From a report: Later, the Senate passed a critical test vote by 67-32, suggesting possible passage of the entire infrastructure bill in the coming days. "This bipartisan deal is the most important investment in public transit in American history and the most important investment in rail since the creation of Amtrak 50 years ago," President Joe Biden said in a statement Wednesday afternoon. "It will deliver high speed internet to every American."

Neither precise details of the broadband section nor the text of the whole bill has been released yet. The White House said in a related statement that a $65 billion investment for broadband, out of $550 billion in new spending, would ensure that "every American has access to reliable high-speed internet," comparing it to the electrification of the country a century ago. The National Telecommunications and Information Administration, part of the Commerce Department, published a comprehensive interactive online map last month. The document shows how poorer, more rural and tribal areas generally don't have affordable broadband access.

More than 90 chief executive officers, including those at Apple, Amazon and Facebook on Thursday urged Congress to pass a law offering a citizenship path to young immigrants brought illegally to the U.S. as children. From a report: In a letter to President Joe Biden and congressional leaders, the executives said thousands of the immigrants -- known as Dreamers -- are "valued employees at our companies," but a federal judge's recent ruling against a program protecting them "throws into chaos" their ability to live and work legally in the U.S. "Securing a pathway to citizenship for Dreamers not only is the right thing to do, but is a huge economic benefit to the United States," the CEOs wrote in the letter. "The latest court ruling makes it all the more urgent that Congress take up and pass a legislative solution right away." The letter seeks to increase pressure on Republicans in Congress who are likely to oppose Democrats' efforts to pass the measure allowing for legal status for as many as 8 million undocumented immigrants.

Amazon's Kindle e-readers with built-in 3G will begin to lose the ability to connect to the internet on their own in the US in December, according to an email sent to customers on Wednesday. The Verge reports: The change is due to mobile carriers transitioning from older 2G and 3G networking technology to newer 4G and 5G networks. For older Kindles without Wi-Fi, this change could mean not connecting to the internet at all. As Good e-Reader first noted in June, newer Kindle devices with 4G support should be fine, but for older devices that shipped with support for 3G and Wi-Fi like the Kindle Keyboard (3rd generation), Kindle Touch (4th generation), Kindle Paperwhite (4th, 5th, 6th, and 7th generation), Kindle Voyage (7th generation), and Kindle Oasis (8th generation), users will be stuck with Wi-Fi only. In its email announcement, Amazon stresses that you can still enjoy the content you already own and have downloaded on these devices, you just won't be able to download new books from the Kindle Store unless you're doing it over Wi-Fi.

Things get more complicated for Amazon's older Kindles, like the Kindle (1st and 2nd generation), and the Kindle DX (2nd generation). Since those devices relied solely on 2G or 3G internet connectivity, once the networks are shut down, the only way to get new content onto your device will be through an old-fashioned micro-USB cable. For customers affected by the shutdown, Amazon is offering a modest promotional credit (NEWKINDLE50) through August 15th for $50 towards a new Kindle Paperwhite or Kindle Oasis, along with $15 in-store credit for ebooks. While arguably the company could do more to help affected customers (perhaps by replacing older devices entirely) this issue is largely out of Amazon's hands.

Facebook said on Wednseday it expects revenue growth to "decelerate significantly." It also announced that it would require anyone working at its U.S. offices to be vaccinated against COVID-19. Google announced a similar policy earlier this morning. Reuters reports: The warning overshadowed the company's beat on Wall Street estimates for quarterly revenue, bolstered by increased advertising spending as businesses build their digital presence to cater to consumers spending more time and money online. Facebook said it expects Apple's recent update to its iOS operating system to impact its ability to target ads and therefore ad revenue in the third quarter. The iPhone maker's privacy changes make it harder for apps to track users and restrict advertisers from accessing valuable data for targeting ads.

Monthly active users came in at 2.90 billion, up 7% from the same period last year but missing analyst expectations of 2.92 billion and marking the slowest growth rate in at least three years, according to IBES data from Refinitiv. "The user growth slowdown is notable and highlights the engagement challenges as the world opens up. But importantly, Facebook is the most exposed to Apple's privacy changes, and it looks like it is starting to have an impact to the outlook beginning in 3Q," said Ygal Arounian, an analyst at Wedbush Securities. Brian Wieser, GroupM's global president of business intelligence, said all social media companies would see slower growth in the second half of the year and that it would take more concrete warnings about activity in June and July for anyone to anticipate a "meaningful deceleration."

Google is postponing a return to the office for most workers until mid-October and rolling out a policy that will eventually require everyone to be vaccinated once its sprawling campuses are fully reopened. The Associated Press reports: The announcement Wednesday came as the more highly contagious delta variant is driving a dramatic spike in COVID-19 cases and hospitalizations. In an email sent to Google's more than 130,000 employees worldwide, CEO Sundar Pichai said the company is now aiming to have most of its workforce back to its offices beginning Oct. 18 instead of its previous target date of Sept. 1. The decision also affects tens of thousands of contractors who Google intends to continue to pay while access to its campuses remains limited. "This extension will allow us time to ramp back into work while providing flexibility for those who need it," Pichai wrote.

And Pichai disclosed that once offices are fully reopened, everyone working there will have to be vaccinated. The requirement will be first imposed at Google's Mountain View, California, headquarters and other U.S. offices, before being extended to the more than 40 other countries where the Google operates. Google's vaccine mandate will be adjusted to adhere to the laws and regulations of each location, Pichai wrote, and exceptions will be made for medical and other "protected" reasons. "Getting vaccinated is one of the most important ways to keep ourselves and our communities healthy in the months ahead," Pichai explained.

An anonymous reader quotes a report from Ars Technica: A security update will be applied to Drive," Google's weird new email reads. If you visit drive.google.com, you'll also see a message saying, "On September 13, 2021, a security update will be applied to some of your files." You can even see a list of the affected files, which have all gotten an unspecified "security update." So what is this all about? Google is changing the way content sharing works on Drive. Drive files have two sharing options: a single-person allow list (where you share a Google Doc with specific Google accounts) and a "get link" option (where anyone with the link can access the file). The "get link" option works the same way as unlisted YouTube videos -- it's not really private but, theoretically, not quite public, either, since the link needs to be publicized somewhere. The secret sharing links are really just security through obscurity, and it turns out the links are actually guessable.

Google knew about the problem of guessable secret links for a while and changed the way link generation works back in 2017 (presumably for Drive, too?). Of course, that doesn't affect links you've shared in the past, and soon Google is going to require your old links to change, which can break them. Google's new link scheme adds a "resourcekey" to the end of any shared Drive links, making them harder to guess. So a link that used to look like "https://drive.google.com/file/d/0BxI1YpjkbX0OZ0prTHYyQ1U2djQ/" will now look like "https://drive.google.com/file/d/0BxI1YpjkbX0OZ0prTHYyQ1U2djQ/view?resourcekey=0-OsOHHiQFk1QEw6vIyh8v_w." The resource key makes it harder to guess. If you head to drive.google.com/drive/update-drives in a browser, you should be able to see a list of your impacted files, and if you mouse over them you'll see a button on the right to remove or apply the security update. "Applied" means the resourcekey will be required after September 13, 2021, and will (mostly) break the old link, while "removed" means the resourcekey isn't required and any links out there should keep working. YouTube is also making similar changes. "In 2017, we rolled out an update to the system that generates new YouTube Unlisted links, which included security enhancements that make the links for your Unlisted videos even harder for someone to discover if you haven't shared the link with them," says YouTube in a support page.

YouTube creators can decide to opt out of this change. They also have the option of making Unlisted pre-2017 videos public or re-uploading as a new Unlisted video at the expense of stats.

Walmart's investments in software and retail technologies it used to transform its business from a brick-and-mortar to one that combines both in-person and online shopping will now be made available to other retailers for the first time, the company announced today. From a report: Through a strategic partnership with Adobe, Walmart will integrate access to Walmart's Marketplace, as well as its various online and in-store fulfillment and pickup technologies, into the Adobe Commerce Platform. The technologies will be made available to both Adobe Commerce and Magento Open Source customers, Adobe says.

The deal will allow Walmart to potentially reach thousands of small to mid-sized retailers, who will effectively be able to tap into the same tools that one of the largest global retailers is using to run their business. Through the partnership, Adobe retail customers will be able to do things like show store pickup eligibility and available pickup times online; offer multiple pickup options like curbside and in-store pickup; provide their store associates with mobile tools to pick for orders, validate item selections and handle substitutions; and use tools to communicate with customers about their pickup orders, like those where customers can alert store associates of their ETA or arrival for curbside pickup. Another aspect of the partnership will allow retailers to syndicate and sell their products across Walmart's Marketplace.

The U.S. economy stands to gain $160 billion a year in extra output from a successful national high-speed internet plan that would boost labor productivity and allow more people to work from home, according to new research. From a report: The study, which is based on survey data, attempts to put precise numbers on one of the bigger unknowns in President Joe Biden's infrastructure plan: how much is universal broadband really worth?

"Moving to high-quality, fully reliable home internet service for all Americans would raise earnings-weighted labor productivity by an estimated 1.1% in the coming years," economists Jose Maria Barrero, Nicholas Bloom and Steven Davis wrote in a paper released July 27. "The implied output gains are $160 billion per year," equivalent to about 0.7% of gross domestic product. The study's authors describe an "abrupt, enormous" shift to remote work as a result of the pandemic, which they expect to settle with about 20% of the U.S. labor force persistently working from home. The share could be higher for so-called knowledge workers whose jobs are mostly done on computer networks anyway.

Two U.S. senators on Wednesday said they are introducing a measure to prohibit funds in a $1.9 trillion government funding measure from being used to purchase Chinese telecommunications equipment from Huawei and ZTE and others deemed U.S. security threats. From a report: Senators Tom Cotton, a Republican, and Mark Warner, a Democrat, said the funds that were approved in March in a law known as the American Rescue Plan should not be used to potentially undermine U.S. telecommunications networks.

More than 40 state attorneys general on Wednesday said they planned to appeal the dismissal of their antitrust lawsuit against Facebook, setting up a protracted legal fight to rein in the power of the Silicon Valley giant. From a report: The states would be pushing back on a decision made last month by a federal judge who eviscerated their arguments that Facebook had obtained a monopoly through its acquisitions of Instagram in 2012 and WhatsApp in 2014 and had harmed competition. The judge said that the regulators' attempts to break up the social media company came too many years after the mergers were approved. "The court is aware of no case, and plaintiffs provide none, where such a long delay in seeking such a consequential remedy has been countenanced in a case brought by a plaintiff other than the federal government," the judge, James E. Boasberg of the U.S. District Court for the District of Columbia, said.

The state attorneys general have 90 days from the date of the notice to file their appeal, including their arguments. Mr. Boasberg also dismissed a similar complaint brought by the Federal Trade Commission, criticizing the agency's claims of monopolization, but he directed the agency to rewrite its lawsuit. The F.T.C. is expected to resubmit its lawsuit to the court by Aug. 19. The states' notice of plan to appeal did not include new antitrust arguments and was filed to the United States Court of Appeals for the District of Columbia Circuit.

China ordered Tencent Holdings and 13 other developers to rectify problems related to pop-ups within their apps, adding to a wide-ranging crackdown on the country's tech sector. From a report: The companies must address the "harassing" pop-up windows, which could contain misleading information or divert users away from the apps, the Ministry of Industry and Information Technology said in a statement on Wednesday. The 14 services, including an e-books app by Tencent's QQ and a video platform by Le.com, will have to fix the problems by Aug. 3. "Failure to abide by regulations" will not be tolerated and will be "penalized" accordingly, said the ministry.

Pop-ups, often used for advertising, are just the latest targets in a series of government crackdowns that have ranged from antitrust to data security, as Beijing seeks to rein in the tech giants' influence over most of everyday life. The crackdown has stepped into high gear in recent days after regulators announced their toughest-ever curbs on the online education sector and issued edicts governing food delivery, fueling a rout in Chinese tech stocks. The statement by MIIT comes days after the regulator announced a six-month crackdown on illegal online activities. The ministry on Monday said it will take steps to root out violations involving pop-ups, data collection and storage as well as the blocking of external links. Other regulators including the Cyberspace Administration of China have also pledged to tighten restrictions on misleading and explicit content used for marketing purposes. The watchdog said such material will be subject to harsher oversight, issuing fines against companies like Tencent, Kuaishou Technology and Alibaba Group Holding Ltd. for offensive content.

theodp writes: The commonly held belief that programming is inherently hard lacks sufficient evidence," begins CS Prof Brett Becker in [an article published in the journal Communications of the ACM]. "Stating this belief can send influential messages that can have serious unintended consequences including inequitable practices. [...] Language is a powerful tool. Stating that programming is hard should raise several questions but rarely does. Why does it seem routinely acceptable -- arguably fashionable -- to make such a general and definitive statement? Why are these statements often not accompanied by supporting evidence? What is the empirical evidence that programming, broadly speaking, is inherently hard, or harder than possible analogs such as calculus in mathematics? Even if that evidence exists, what does it mean in practice? In what contexts does it hold? To whom does it, and does it not, apply?"

Becker concludes: "Blanket messages that 'programming is hard' seem outdated, unproductive, and likely unhelpful at best. At worst they could be truly harmful. We need to stop blaming programming for being hard and focus on making programming more accessible and enjoyable, for everyone.
