An asteroid-hunting algorithm called HelioLinc3D has spotted a potentially hazardous 600-foot-long space rock that's currently about 4 astronomical units from Earth. The asteroid is 2022 SF289 and "swings by Earth on the opposite side of its orbit, classifying it as a potentially hazardous asteroid (or PHA)," reports Gizmodo. From the report: "Potentially hazardous" merely means there is some chance the object could impact Earth, and thus it is worth keeping an eye on. What's significant about 2022 SF289 is not that it is hazardous, but that it was spotted by a new algorithm called HelioLinc3D. The recent asteroid spotting demonstrated that the algorithm can detect near-Earth asteroids with fewer observations than traditional methods. Because the Rubin Observatory is not yet up and running, HelioLinc3D was tested using the University of Hawaii's ATLAS survey.

"By demonstrating the real-world effectiveness of the software that Rubin will use to look for thousands of yet-unknown potentially hazardous asteroids, the discovery of 2022 SF289 makes us all safer," said Ari Heinze, a scientist and researcher at the Rubin Observatory and the University of Washington, and the principal developer of the new algorithm, in a university release. "This is just a small taste of what to expect with the Rubin Observatory in less than two years, when HelioLinc3D will be discovering an object like this every night," said Mario Juric, a scientist at the Rubin Observatory, director of the DiRAC Institute, astronomer at the University of Washington, and leader of the team behind HelioLinc3D, in the same release.

"From HelioLinc3D to AI-assisted codes, the next decade of discovery will be a story of advancement in algorithms as much as in new, large, telescopes," Juric added. The Rubin Observatory is now expected to commence its observations in early 2025, though we'll have to wait and see if that timeline sticks.

Some of the largest tech companies, including Adobe, Apple, Autodesk, and Nvidia, have announced the Alliance for OpenUSD (AOUSD) to promote and develop Pixar's 3D Universal Scene Description technology. From the Linux Foundation: The alliance seeks to standardize the 3D ecosystem by advancing the capabilities of Open Universal Scene Description (OpenUSD). By promoting greater interoperability of 3D tools and data, the alliance will enable developers and content creators to describe, compose, and simulate large-scale 3D projects and build an ever-widening range of 3D-enabled products and services. Created by Pixar Animation Studios, OpenUSD is a high-performance 3D scene description technology that offers robust interoperability across tools, data, and workflows. Already known for its ability to collaboratively capture artistic expression and streamline cinematic content production, OpenUSD's power and flexibility make it an ideal content platform to embrace the needs of new industries and applications.

The alliance will develop written specifications detailing the features of OpenUSD. This will enable greater compatibility and wider adoption, integration, and implementation, and allows inclusion by other standards bodies into their specifications. The Linux Foundation's JDF was chosen to house the project, as it will enable open, efficient, and effective development of OpenUSD specifications, while providing a path to recognition through the International Organization for Standardization (ISO). AOUSD will also provide the primary forum for the collaborative definition of enhancements to the technology by the greater industry. The alliance invites a broad range of companies and organizations to join and participate in shaping the future of OpenUSD.

Long-time Slashdot reader lpq shares a report from Fortune: We're now finding out the damaging consequences of the mandated return to office. And it's not a pretty picture. A trio of compelling reports -- the Greenhouse Candidate Experience report, the Federal Reserve's Survey of Household Economics and Decisionmaking (SHED), and Unispace's Returning for Good report -- collectively paint a stark picture of this brewing storm. Unispace found that nearly half (42%) of companies with return-to-office mandates witnessed a higher level of employee attrition than they had anticipated. And almost a third (29%) of companies enforcing office returns are struggling with recruitment. In other words, employers knew the mandates would cause some attrition, but they weren't ready for the serious problems that would result.

Meanwhile, a staggering 76% of employees stand ready to jump ship if their companies decide to pull the plug on flexible work schedules, according to the Greenhouse report. Moreover, employees from historically underrepresented groups are 22% more likely to consider other options if flexibility comes to an end. In the SHED survey, the gravity of this situation becomes more evident. The survey equates the displeasure of shifting from a flexible work model to a traditional one to that of experiencing a 2% to 3% pay cut.

Flexible work policies have emerged as the ultimate edge in talent acquisition and retention. The Greenhouse, SHED, and Unispace reports, when viewed together, provide compelling evidence to back this assertion. Greenhouse finds that 42% of candidates would outright reject roles that lack flexibility. In turn, the SHED survey affirms that employees who work from home a few days a week greatly treasure the arrangement. Interestingly, Unispace throws another factor into the mix: choice. According to its report, overall, the top feelings employees revealed they felt toward the office were happy (31%), motivated (30%), and excited (27%). However, all three of these feelings decrease for those with mandated office returns (27%, 26%, and 22%, respectively). In other words, staff members were more open to returning to the office if it was out of choice, rather than forced.

Starting today, Facebook and Instagram users in Canada will no longer be able to view or share news links or see videos and photos published by publishers and broadcasters. Engadget reports: Meta made the decision in response to Canadian legislators passing the Online News Act. The law requires certain platforms to negotiate revenue-sharing agreements with news organizations. The aim is to address the collapse in advertising revenue that news outlets have struggled with over the last two decades amid the growth of online services.

"News links and content posted by news publishers and broadcasters in Canada will no longer be viewable by people in Canada," Meta said. "We are identifying news outlets based on legislative definitions and guidance from the Online News Act." Any content shared by international news organizations won't be visible on Facebook and Instagram in Canada either.

An anonymous reader quotes a report from Politico: President Joe Biden has determined that Colorado Springs will be the permanent headquarters of U.S. Space Command, reversing a Trump administration decision to move the facility to Alabama, the Pentagon announced Monday. The decision will only intensify a bitter parochial battle on Capitol Hill, as members of the Colorado and Alabama delegations have spent months accusing each other of playing politics on the future of the four-star command.

The command was reestablished in 2019 and given temporary headquarters in Colorado while the Air Force evaluated a list of possible permanent sites. With an eye on Russia and China, its job is to oversee the military's operations of space assets and the defense of satellites. Pentagon spokesperson Brig. Gen. Pat Ryder said Biden notified the Department of Defense on Monday that he had made the decision, after speaking with Defense Secretary Lloyd Austin and weighing the input of senior military leaders. "Locating Headquarters U.S. Space Command in Colorado Springs ultimately ensures peak readiness in the space domain for our nation during a critical period," Ryder said in a statement. "It will also enable the command to most effectively plan, execute and integrate military spacepower into multi-domain global operations in order to deter aggression and defend national interests." Austin, Air Force Secretary Frank Kendall and U.S. Space Command chief Gen. James Dickinson all support Biden's decision, Ryder added.

The most significant factor Biden weighed in making the decision was the impact such a move would have on the military's ability to confront the changing threat from space, according to a senior administration official, who like others was granted anonymity to discuss sensitive deliberations. Keeping the headquarters at Colorado Springs "maintains operational readiness and ensures no disruption to its mission or to its personnel," according to the official. The command is set to achieve "full operational capability" this month, the official said. A move to Alabama, by contrast, would have forced the command to transition to a new headquarters in the mid-2020s, and the new site would not have been open until the early to mid-2030s, the official said. "The president found that risk unacceptable, especially given the challenges we may face in the space domain during this critical time period," according to the official.

Derek Lowe, a medicinal chemist and freelance writer on science and pharmaceutical topics, comments on the latest developments around last week's remarkable claim of a well-above-room-temperature superconducting material at ambient pressure, dubbed LK-99. Here's an excerpt from his post: As of this morning, there are (as yet not really verified) reports of replication from the Huazhong University of Science and Technology in China. At least, a video has been posted showed what could be a sample of LK-99 levitating over a magnet due to the Meissner effect, and in different orientations relative to the magnet itself. That's important, because a (merely!) paramagnetic material can levitate in a sufficiently strong field (as can diamagnetic materials like water droplets and frogs), but these can come back to a particular orientation like a compass needle. Superconductors are "perfect diamagnets," excluding all magnetic fields, and that's a big difference. The "Meissner effect" that everyone has been hearing about so much is observed when a material first becomes superconductive at the right temperature and expels whatever magnetic fields were penetrating it at the time. All this said, we're having to take the video on the statements of whoever made/released it, and there are other possible explanations for the it that do not involve room-temperature superconductivity. I will be very happy if this is a real replication, but I'm not taking the day off yet to celebrate just based on this.

And even though I'm usually more of an experimental-results guy than a theory guy, two other new preprints interest me greatly. One is from a team (PDF) at the Shenyang National Laboratory for Materials Science, and the other (PDF) is from Sinead Griffin at Lawrence Berkeley. Both start from the reported X-ray structural data of LK-99 and look at its predicted behavior via density functional theory (DFT) calculations. And they come to very similar conclusions: it could work. This is quite important, because this could mean that we don't need to postulate completely new physics to explain something like LK-99 - if you'd given the starting data to someone as a blind test, they would have come back after the DFT runs saying "You know, this looks like it could be a really good superconductor..." [...]

I am guardedly optimistic at this point. The Shenyang and Lawrence Berkeley calculations are very positive developments, and take this well out of the cold-fusion "we can offer no explanation" territory. Not that there's anything wrong with new physics (!), but it sets a much, much higher bar if you have to invoke something in that range. I await more replication data, and with more than just social media videos backing them up. This is by far the most believable shot at room-temperature-and-pressure superconductivity the world has seen so far, and the coming days and weeks are going to be extremely damned interesting.

An anonymous reader quotes a report from Ars Technica: Film companies lost another attempt to force Reddit to identify anonymous users who discussed piracy. A federal court on Saturday quashed a subpoena (PDF) demanding users' names and other identifying details, agreeing with Reddit's argument that the film companies' demands violate the First Amendment. The plaintiffs are 20 producers of popular movies who are trying to prove that Internet service provider Grande is liable for its subscribers' copyright infringement because the ISP allegedly ignores piracy on its network. Reddit isn't directly involved in the copyright case. But the film companies filed a motion to compel Reddit to respond to a subpoena demanding "basic account information including IP address registration and logs from 1/1/2016 to present, name, email address and other account registration information" for six users who wrote comments on Reddit threads in 2011 and 2018.

"The issue is whether that discovery is permissible despite the users' right to speak anonymously under the First Amendment," US Magistrate Judge Laurel Beeler wrote in her ruling against the film copyright holders. "The court denies the motion because the plaintiffs have not demonstrated a compelling need for the discovery that outweighs the users' First Amendment right to anonymous speech." The film companies seeking Reddit users' identities include After II Movie LLC, Bodyguard Productions, Hitman 2 Productions, Millennium Funding, Nikola Productions, Rambo V Productions, and Dallas Buyers Club LLC. As Beeler's ruling on Saturday noted, they sought the identities of two users who wrote about torrenting on Grande's network in 2018 [...]. The companies also sought identities of four users who commented in a 2011 thread. "I have grande. No issues with torrent or bandwidth caps," one user comment said. Another Reddit user wrote, "I have torrented like a motherfucker all over grande and have never seen anything." Reddit's filing (PDF) pointed out that the statute of limitations for copyright infringement is three years. The film companies said (PDF) the statute of limitations is irrelevant to whether the comments can provide evidence in the case against Grande.

An anonymous reader quotes a report from Ars Technica: Starting today, Facebook users may feel a little less safe posting anonymously. The Court of the Hague in The Netherlands ruled that Meta Ireland must unmask an anonymous user accused of defaming the claimant, a male Facebook user who allegedly manipulated and made secret recordings of women he dated. The anonymous Facebook user posted the allegedly defamatory statements in at least two private Facebook groups dedicated to discussing dating experiences. The claimant could not gain access but was shown screenshots from the groups, one with about 2,600 members and one with around 61,000 members. The claimant argued that his reputation had suffered from the repeated postings that included photos of the man and alleged screenshots of his texts.

The claimant tried to get Meta to remove the posts, but Meta responded with an email saying that it would not do so because "it is not clear to us that the content you reported is unlawful as defamation." At that point, Meta suggested that the man contact the anonymous user directly to resolve the matter, triggering the lawsuit against Meta. Initially, the claimant asked the court to order Meta to delete the posts, identify the anonymous user, and flag any posts in other private Facebook groups that could defame the claimant. While arguing the case, Meta had defended the anonymous user's right to freedom of expression, but the court decided that the claimant -- whose name is redacted in court documents -- deserved an opportunity to challenge the allegedly defamatory statements. Partly for that reason, the court ordered Meta to provide "basic subscriber information" on the anonymous user, including their username, as well as any names, email addresses, or phone numbers associated with their Facebook account. The court did not order Meta to remove the posts or flag any others that may have been shared in private groups, though.

Meta has already agreed to comply with the order, the court's ruling said. However, if Meta fails to provide the Facebook user's identifying information, the social media company risks a penalty of approximately $1,200 daily. The maximum fine that Meta could face is less than $130,000. [...] Meta's defense of the anonymous user's right to free speech failed, the court said, because freedom of speech is not unlimited. "Someone who, without evidence, repeatedly makes serious and clearly traceable accusations, must take into account, partly in the light of the conditions applied by Facebook, that he or she may be confronted with a measure whereby his or her anonymity is lifted," the court order said. Although the key concern for The Court in the Hague appeared to be that the statements posted anonymously were plausibly defamatory, the order also noted that the content would not have to necessarily be unlawful for Facebook to be ordered to identify the user posting it. "According to settled case law, under certain circumstances Meta has an obligation to provide identifying data, even if the content of the relevant messages is not unmistakably unlawful," the court order said.

Long-time Slashdot reader nairnr shares a report from The Register: Cloud giant AWS will start charging customers for public IPv4 addresses from next year, claiming it is forced to do this because of the increasing scarcity of these and to encourage the use of IPv6 instead. It is now four years since we officially ran out of IPv4 ranges to allocate, and since then, those wanting a new public IPv4 address have had to rely on address ranges being recovered, either from from organizations that close down or those that return addresses they no longer require as they migrate to IPv6.

If Amazon's cloud division is to be believed, the difficulty in obtaining public IPv4 addresses has seen the cost of acquiring a single address rise by more than 300 percent over the past five years, and as we all know, the business is a little short of cash at the moment, so is having to pass these costs on to users. "This change reflects our own costs and is also intended to encourage you to be a bit more frugal with your use of public IPv4 addresses and to think about accelerating your adoption of IPv6 as a modernization and conservation measure,' writes AWS Chief Evangelist Jeff Barr, on the company news blog.

The update will come into effect on February 1, 2024, when AWS customers will see a charge of $0.005 (half a cent) per IP address per hour for all public IPv4 addresses. These charges will apparently apply whether the address is attached to a service or not, and like many AWS charges, appear inconsequential at first glance but can mount up over time if a customer is using many of them. These charges will apply to all AWS services including EC2, Relational Database Service (RDS) database instances, Elastic Kubernetes Service (EKS) nodes, and will apply across all AWS regions, the company said. However, customers will not be charged for IP addresses that they own and bring to AWS using Amazon's BYOIP feature. AWS offers a free tier for EC2, and this will include 750 hours of public IPv4 address usage per month for the first 12 months, starting from the same date the charges do.

Bitcoin ATM operator LibertyX now offers bitcoin purchases at the United States' most popular convenience and drug stores. From a report: Per a PR Newswire released on Jun 22, the company has finished rolling out the buying option which will be available in "20,000 retail locations around the U.S., including major convenience store and pharmacy chains, such as 7-Eleven, CVS Pharmacy, and Rite Aid." This service will give LibertyX users the option to purchase bitcoin with cash at any of the participating retailers' cashier counters. These 20,000 new buying centers add to the 5,000 Bitcoin ATMs that the company has established across the United States since it launched in 2014.

Dr. Anthony Fauci, the government's top infectious disease expert, told a House committee on Tuesday he believes "it will be when and not if" there will be a COVID-19 vaccine and that he remains "cautiously optimistic" that some will be ready at the end of the year. From a report: Fauci has returned to Capitol Hill at a fraught moment in the nation's pandemic response, with coronavirus cases rising in about half the states and political polarization competing for attention with public health recommendations. Fauci testified in his opening statement that a vaccine candidate for the coronavirus will enter Phase 3 of study in July. "This is one that has already shown in preliminary studies some very favorable response in the animal models that we've developed," Fauci said. Earlier this month, Cambridge-based Moderna announced the experimental COVID-19 vaccine it is developing with the US National Institutes of Health was on track to be tested in 30,000 volunteers -- some given the real shot and some a dummy shot.

Fauci was testifying along with the heads of the Centers for Disease Control and Prevention, the Food and Drug Administration, and a top official at the Department of Health and Human Services. Since Fauci's last appearance at a high-profile hearing more than a month ago, the US has been emerging from weeks of stay-at-home orders and business shutdowns. But it's being done in an uneven way, with some states far less cautious than others. A trio of states with Republican governors who are bullish on reopening -- Arizona, Florida and Texas -- are among those seeing worrisome increases in cases. Last week, Vice President Mike Pence published an opinion article in The Wall Street Journal saying the administration's efforts have strengthened the nation's ability to counter the virus and should be "a cause for celebration." Dr. Fauci also told lawmakers Tuesday that the US will be increasing coronavirus testing, saying, "we're going to be doing more testing, not less," in response to President Donald Trump's recent claim that he asked to slow down testing during the pandemic.
