Boeing's 'Starliner' Also Experienced an Issue on Its Return to Earth
Friday the Orlando Sentinel covered NASA's 2024 mission-safety report from the Aerospace Safety Advisory Panel (formed in 1968). The report "commended the agency's handling of last year's beleaguered Boeing's Starliner mission [prioritizing astronaut safety], but revealed yet another issue found during the flight and questioned the agency's needs for the spacecraft in the future..."
[The report] stated that it was unclear how a decision was made to waive a failure tolerance requirement on some of the thrusters without flight or qualification data to justify the decision. "These examples illustrate the panel's concern that, absent role clarity, risk management choices could unintentionally devolve to contractors, whose interests may not fully align with NASA's," the report warned...
It also revealed that in addition to the thruster and leak issues on the propulsion module driving the decision to fly home without astronauts, Starliner had a new issue as it made its way back to Earth. "Overall, Starliner performed well across all major systems in the undock, deorbit, and landing sequences; however, an additional mono propellant thruster failure was discovered in the crew module — distinct from the failures in the service module experienced during orbit," the report stated. "Had the crew been aboard, this would have significantly increased the risk during reentry, confirming the wisdom of the decision."
As far as Starliner's path to certification, the ASAP report said it would continue to monitor several unresolved issues with thrusters and seek information on how NASA and Boeing plan to get the spacecraft certified. "While the thruster issues have received considerable attention, the panel has previously noted other Starliner issues that require resolution prior to certification," it stated. That includes a battery redesign and work to strengthen the landing airbag apparatus. "Beyond these technical matters, schedule and budget pose substantial challenges to Starliner certification," the report added...
"Until the Starliner certification plan is well understood, it remains unclear as to whether a second provider will be available prior to the end of the ISS's operational life [in 2030]," the report stated.
The report "also suggested that NASA immediately adapt next-generation extravehicular mobility units, or EVUs," reports ExecutiveGov, "as current space suits astronauts use for operations outside the ISS are now beyond their design life."

While TikTok Buys Ads on YouTube, YouTube is Buying Ads on TikTok
I just saw an ad for TikTok on a YouTube video. But at the same time YouTube is running ads on TikTok, reports Bloomberg, targeting TikTok content creators in "an effort to lure these valuable users to the Google-owned rival and capitalize on TikTok's uncertain future."
One of YouTube's ads even received over a thousand likes, with Bloomberg calling it that TikTok "is willing to accept ad dollars from one of its fiercest competitors promoting a message aimed at undercutting its business."
YouTube is the latest TikTok competitor to try to capitalize on the app's looming US ban, which could go into effect in early April. Meta Platforms Inc.'s Instagram announced a new video editing tool in January, and X also teased a new video tab as part of an effort to win over TikTok's content creators...
Google would be one of the biggest beneficiaries of a ban in the US. Both its flagship video service YouTube and its TikTok copycat, YouTube Shorts, would likely see an uptick in traffic if TikTok goes away. Google also plays an unusual role in TikTok's potential ban because it runs one of two mobile app stores controlling whether people in the US can download the video app. It has blocked TikTok from its Google Play store since the divest-or-ban law went into effect January 19.

California Tech Founder Admits to Defrauding $4M For His Luxury Lifestyle
The tech startup "purported to make smart home and business products," writes America's Justice Department — products that were "meant to stop package theft, prevent weather damage to packages, and make it easier for emergency responders and delivery services to find homes and businesses." Royce Newcomb "developed prototypes of his products and received local and national media attention for them. For example, Time Magazine included his eLiT Address Box & Security System, which used mobile networks to pinpoint home and business locations, on its Best Inventions of 2021 list."
But then he told investors he'd also received a grant by the National Science Foundation — one of "several false representations to his investors to deceive and cheat them out of their money... Newcomb used the money to pay for gambling, a Mercedes and Jaguar, and a mansion."
He also used the money to pay for refunds to other investors who wanted out, and to pay for new, unrelated projects without the investors' authorization. During this period, Newcomb also received a fraudulent COVID-19 loan for more than $70,000 from the Small Business Administration and fraudulent loans for more than $190,000 from private lenders. He lied about Strategic Innovations having hundreds of thousands and even millions in revenue to get these loans.
Newcomb was previously convicted federally in 2011 for running a real estate fraud scheme in Sacramento. He was sentenced to more than five years in prison for that offense, and he was on federal supervised release for that offense when he committed the offenses charged in this case... Newcomb faces maximum statutory penalties of 20 years in prison and a $250,000 fine for the wire fraud charge, and 10 years in prison and a $250,000 fine for the money laundering charge...
This effort is part of a California COVID-19 Fraud Enforcement Strike Force operation, one of five interagency COVID-19 fraud strike force teams established by the U.S. Department of Justice.
SFGate writes that "Despite receiving significant funding, his startup, Strategic Innovations, never made a dime or released any products to market, according to legal documents."
The owner of a California tech startup has pleaded guilty to stealing over $4 million from investors, private lenders and the U.S. government in order to live a luxurious lifestyle, the United States Attorney's Office announced Monday... When investors asked about product delays and when they'd be paid back, Newcomb made excuses and provided conflicting info, telling them that there were supply chain issues or software problems, according to the indictment. In reality, federal prosecutors said, he was using the money to travel and continue to make these lavish personal expenses.

Does the 'Spirit' of Open Source Mean Much More Than a License?
"Open source can be something of an illusion," writes TechCrunch. "A lack of real independence can mean a lack of agency for those who would like to properly get involved in a project."
Their article makes the case that the "spirit" of open source means more than a license...
"Android, in a license sense, is perhaps the most well-documented, perfectly open 'thing' that there is," Luis Villa, co-founder and general counsel at Tidelift, said in a panel discussion at the State of Open Con25 in London this week. "All the licenses are exactly as you want them — but good luck getting a patch into that, and good luck figuring out when the next release even is...."
"If you think about the practical accessibility of open source, it goes beyond the license, right?" Peter Zaitsev, founder of open source database services company Percona, said in the panel discussion. "Governance is very important, because if it's a single corporation, they can change a license like 'that.'" These sentiments were echoed in a separate talk by Dotan Horovits, open source evangelist at the Cloud Native Computing Foundation (CNCF), where he mused about open source "turning to the dark side." He noted that in most cases, issues arise when a single-vendor project decides to make changes based on its own business needs among other pressures. "Which begs the question, is vendor-owned open source an oxymoron?" Horovits said. "I've been asking this question for a good few years, and in 2025 this question is more relevant than ever."
The article adds that in 2025, "These debates won't be going anywhere anytime soon, as open source has emerged as a major focal point in the AI realm." And it includes this quote from Tidelift's co-founder.
"I have my quibbles and concerns about the open source AI definition, but it's really clear that what Llama is doing isn't open source," Villa said.
Emily Omier, a consultant for open source businesses and host of the Business of Open Source podcast, added that such attempts to "corrupt" the meaning behind "open source" is testament to its inherent power.
Much of this may be for regulatory reasons, however. The EU AI Act has a special carve-out for "free and open source" AI systems (aside from those deemed to pose an "unacceptable risk"). And Villa says this goes some way toward explaining why a company might want to rewrite the rulebook on what "open source" actually means. "There are plenty of actors right now who, because of the brand equity [of open source] and the regulatory implications, want to change the definition, and that's terrible," Villa said.

El Salvador Congress Votes to Revoke Bitcoin's 'Legal Currency' Status
After finalizing loan terms with the IMF, El Salvador's Legislative Assembly approved changes to the country's Bitcoin Law last week by a 55-2 vote, "effectively removing bitcoin's status as legal currency," reports Reason.
Under the new rules, bitcoin is no longer considered "currency," though it remains "legal tender." Another change makes using bitcoin entirely voluntary. (Previously, the law mandated that businesses accept bitcoin for any goods or services they provided.) Additionally, bitcoin can no longer be used to pay taxes or settle government debts. The government is also stepping back from its involvement in Chivo Wallet, the state-backed digital wallet...
The reforms come as part of a broader financial agreement between Bukele and the International Monetary Fund (IMF). One of the conditions for a proposed $1.4 billion Extended Fund Facility loan was that El Salvador mitigate "potential risks of the Bitcoin project." The IMF has been critical of the country's crypto policies since Bukele made bitcoin legal tender in 2021. "There are large risks associated with using Bitcoin as legal tender, especially given the high volatility of its price. We don't recommend it," the organization said in 2022.
Despite these changes, the administration insists it remains committed to bitcoin. Milena Mayorga, El Salvador's ambassador to the United States, has said that El Salvador is still a "bitcoin country" and will maintain — and even expand — its bitcoin reserves. "You have to adapt to the current situation and this is the decision that was taken in the Assembly, but that does not mean that the country will stop having a bitcoin reserve," she explained.
Government data suggests El Salvador now holds 6,072 Bitcoin worth $586,888.

Twisted Graphene Sheets Reveal 'Unconventional' Superconductivity Governed by Quantum Geometry
Twisting two atomically thin sheets of graphene enables "a host of exceptional properties," writes MIT News, "including unconventional superconductivity." (Which makes this graphene "a promising building block for future quantum-computing devices.")
And now "We find the superfluid stiffness to be much larger than expected..." a team of researchers reported this week in Nature. Hackaday explains that "Part of the problem has been that it is hard to make large pieces of multi-layer graphene. By creating two-ply pieces and using special techniques, an international team is finding that quantum geometry explains how graphene superconductors resist changes in current flow more readily than conventional superconductors."
Or, as Science Alert puts it, "Forced to run a labyrinth of carbon atoms uniquely arranged in twisted stacks, electrons do some rather peculiar things."
Researchers from the University of British Columbia in Canada, the University of Washington and Johns Hopkins University in the US, and the National Institute for Materials Science in Japan recently discovered a strange new state of matter in the dynamics of currents flowing through layers of graphene.
The findings confirm predictions on how electrons ought to behave when squeezed into crystalline arrangements, and may contribute fresh ideas on how to achieve reliable approaches to quantum computing or reveal ways to develop room-temperature superconduction... Graphene has been increasingly seen as something of a wonder material over recent decades, its lattice of carbon atoms connected in a way that leaves spare electrons to leap about like tokens in a game of quantum checkers. Physicists have consistently bent the rules of this game, finding new and unusual ways to alter properties of resistance or coordinate into exotic states. For these reasons, graphene has become a perfect playground to search for clues on low-resistance conductivity or test the boundaries of various quantum effects.
This week MIT research scientist Joel Wang (a co-lead on the study) said "There's a whole family of 2D superconductors that is waiting to be probed, and we are really just scratching the surface." New Scientist explores where their research could lead:
Why do cold thin sheets of carbon offer no resistance to electric currents? Two experiments are bringing us closer to an answer — and maybe even to practical room-temperature superconductors... Past experiments have shown that very cold stacks of two or three layers of graphene can superconduct, or perfectly conduct electricity without resistance and energy loss, if some of the sheets are rotated by a special angle. But why this happens remained mysterious... [B]oth teams had to innovate a setup where the tiny graphene flakes were exposed to microwaves while the researchers slowly varied properties like temperature, which must be kept very low for superconductivity to occur at all...
"We are finding interesting laws which seem to emerge in both these material systems. Maybe what we are uncovering is something deeper," says [Harvard postdoctoral researcher Abhishek Banerjee]. Both teams are planning on performing similar experiments with other very thin superconductors.

Volkswagen Announces a Cheap Electric Car to Compete With China
An anonymous reader shared this report from the Telegraph:
Volkswagen has teased plans for a "China-killer" electric vehicle that will cost just €20,000 ($20,664 USD or £16,700) as the German carmaker gears up to take on a flood of Beijing-backed low-cost rivals. The company on Thursday shared its first images of a new vehicle expected to be called the ID.1, which will go into production from 2027.
The low-cost EV is intended to go head to head with all-electric brands from Chinese carmakers such as BYD, which overtook Tesla in British sales for the first time last month. Previous images of the vehicle suggest it will be an electric hatchback. Thomas Schäfer, the VW chief executive, said the new model would be "an affordable, high-quality, profitable electric Volkswagen from Europe, for Europe". Quentin Willson, the motoring journalist and founder of FairCharge, said the car could be a "possible China EV killer". Dan Caesar, of Electric Vehicles UK, added: "Cheaper EVs are exactly what legacy auto-makers need to be competitive during this critical time. We would expect the ID.1 to be warmly welcomed by motorists." Ginny Buckley, of consumer advice website Electrifying, said Volkswagen had been "clear about its intent to compete with China's low-cost EVs"...
The German carmaker is planning to cut 35,000 jobs by 2030 as it grapples with stalled demand for EVs in Europe and growing competition from Chinese rivals.
Volkswagen executives describe the upcoming EV will be a "true Volkswagen for everyone," according to the article
It also notes that the number of EVs sold across Europe "fell by 3% to 3 million during 2024, according to data from analysts Rho Motion."

The FSF Will Auction the Original GNU Logo Drawing, Stallman's Medal, and an Amiga
The Free Software Foundation "hinted that it would organize an unprecedented virtual memorabilia auction" in March to celebrate this year's 40th anniversary, according to an announcement this week. Those hints "left collectors and free software fans wondering which of the pieces of the FSF's history would be auctioned off."
But Tuesday the FSF "lifted the veil and gave a sneak peak of some of the more prestigious entries in the memorabilia auction."
First of all, the memorabilia auction will feature an item that could be especially interesting for art collectors but will certainly also draw the attention of free software fans from all over: the original GNU head drawing by Etienne Suvasa, which became the blueprint for the iconic GNU logo present everywhere in the free software world.
The list of memorabilia for sale also entails some rare and historic hardware, such as a "terminus-est" microcomputer, and an Amiga 3000UX that was used in the FSF's old office at the Massachusetts Institute of Technology (MIT) in the early days of GNU, when these machines were capable of running a GNU-like operating system. Another meaningful item to be auctioned off, and one that collectors will want to keep a keen eye on, is the Internet Hall of Fame medal awarded to founder Richard Stallman. When Stallman was inducted into the Internet Hall of Fame, it was the ultimate recognition of free software's immense impact on the development and advancement of the Internet. This medal is definitely worthy of joining a fine historical collection...! [T]here are several more historic awards, more original GNU artwork, and a legendary katana [as seen in an XKCD comic] that became a lighthearted weapon in the fight for computer user freedom.
The auction is only the opening act to a whole agenda of activities celebrating forty years of free software activism. In May, the FSF invites free software supporters all over the world to gather for local in-person community meetups to network, discuss what people can do next to make the world freer, and celebrate forty years of commitment to software freedom. Then, on the actual birthday of the FSF on October 4, 2025, the organization intends to bring the international free software community to Boston for a celebration featuring keynotes and workshops by prominent personalities of the free software movement.
"The bidding will start as a virtual silent auction on March 17 and run through March 21, with more auction items revealed each day, and will culminate in an virtual live auction on March 23, 2025, 14:00 to 17:00 EDT," according to the announcement.
"Register here to attend the live auction. There's no need to register for the silent auction; you can simply join the bidding on the FSF's LibrePlanet wiki."

DeepSeek IOS App Sends Data Unencrypted To ByteDance-Controlled Servers
An anonymous Slashdot reader quotes a new article from Ars Technica: On Thursday, mobile security company NowSecure reported that [DeepSeek] sends sensitive data over unencrypted channels, making the data readable to anyone who can monitor the traffic. More sophisticated attackers could also tamper with the data while it's in transit. Apple strongly encourages iPhone and iPad developers to enforce encryption of data sent over the wire using ATS (App Transport Security). For unknown reasons, that protection is globally disabled in the app, NowSecure said. Whatâ(TM)s more, the data is sent to servers that are controlled by ByteDance, the Chinese company that owns TikTok...
[DeepSeek] is "not equipped or willing to provide basic security protections of your data and identity," NowSecure co-founder Andrew Hoog told Ars. "There are fundamental security practices that are not being observed, either intentionally or unintentionally. In the end, it puts your and your company's data and identity at risk...." This data, along with a mix of other encrypted information, is sent to DeepSeek over infrastructure provided by Volcengine a cloud platform developed by ByteDance. While the IP address the app connects to geo-locates to the US and is owned by US-based telecom Level 3 Communications, the DeepSeek privacy policy makes clear that the company "store[s] the data we collect in secure servers located in the People's Republic of China...." US lawmakers began pushing to immediately ban DeepSeek from all government devices, citing national security concerns that the Chinese Communist Party may have built a backdoor into the service to access Americans' sensitive private data. If passed, DeepSeek could be banned within 60 days.

White House Moves to Halt Federal Funds for EV Charging Stations
Thursday the White House "moved to halt a $5 billion initiative to build electric vehicle charging stations," reports Politico, "by instructing states not to spend federal funds previously allocated to them..." NPR described the move as "putting in limbo billions of dollars allocated to states with current and future projects..."
Politico notes the move "appears to upend years of precedent in which federal promises of funds for highway projects had given states an all-but-guaranteed assurance that they were free to spend them. It also raises legal questions... Funding experts had told POLITICO last year that decades of legal precedent would largely insulate the charging money...
Andrew Rogers [deputy administrator of the Federal Highway Administration, or FHWA, in the Biden administration] said in a text message that the new letter "appears to ignore both the law and multiple restraining orders that have been issued by federal courts." Rogers, who is now a senior vice president at Boundary Stone Partners, said the move appears to be "in direct violation" of the Impoundment Control Act of 1974, a Watergate-era law that prohibits presidents from unilaterally canceling congressionally approved spending. Trump has contended that the law is unconstitutional.
Politico also got a quote from the chief analyst at analytics firm Paren, who predicts lawsuits from affected states and that the final impact of the move will be "just causing havoc and slowing things down for awhile."
[A letter to state transportation directors from the Federal Highway Administration] clarifies that states will be able to receive reimbursements for "existing obligations" to design and build stations "in order to not disrupt current financial commitments." According to the letter, FHWA plans to publish new draft guidance on the NEVI program in the spring, followed by a comment period, before issuing new final guidance. Only then will states be able to resubmit their annual implementation plans for all fiscal years of the program.
"But that doesn't mean that the the program is going to be sunset or the funds are not going to be made available again to the states," Nick Nigro, the founder of Atlas Public Policy consultancy told NPR:
Several experts tell NPR that as a result of its overwhelming bipartisan support at the time, attempts to overturn it within the executive branch are likely to be challenged in court. Nigro believes the funding will resume eventually...
So far, 56 stations [with multiple chargers] are up and running as a result of the program, while more than 900 sites in total have been "awarded" to date, according to Loren McDonald, chief analyst at Paren, another research analytics firm. McDonald said several hundred of the awarded sites are currently under construction and expected to open this year. He does not believe the FHWA has the authority to pause or rescind any aspect of the NEVI program... "I assume lawsuits from states will start soon, and this will go to court and Congress," McDonald said in a statement.
The move has "confounded states, which had been allocated billions of dollars by Congress for the program," the New York Times reported Friday. "[S]ome state officials said that as a result of the memo from the Trump administration, they had stopped work on the charging stations. Others said they intended to keep going."
The Washington Post reports that a Texas Department of Transportation official "said it would continue to deploy federal funds for EV chargers until it receives further guidance," and that Ryan Gallentine, managing director at the national business association Advanced Energy United, said that states "are under no obligation to stop these projects based solely on this announcement."
Politico adds:
Also on Thursday, FHWA took down several internet pages providing information on NEVI and its sister program, the $2.5 billion Charging and Fueling Infrastructure grant program... Amid the confusion, at least six states — Alabama, Oklahoma, Missouri, Rhode Island, Ohio and Nebraska — have put their NEVI programs on hold, according to McDonald. Rhode Island and Ohio had been considered leading states in implementing the program.

Internet Archive Celebrates New Public Domain Works with Remixes in Short Film Contest
To celebrate 3035's newest arrivals in the public domain, the Internet Archive held a special in-person event at their San Francisco headquarters, as well as a virtual celebration online. (It opens with an absolutely gorgeous rendition of "Happy Days are Hear Again" played on a musical saw.)
And somewhere in the festivities they announced the winners of this year's annual "Public Domain Day Film Remix Contest."
These remarkable films not only reimagined and transformed public domain works but also demonstrated the boundless potential of remixing creative works to create something new... Explore all 140+ submissions at the 2025 Public Domain Day Film Remix Contest collection at the Internet Archive...
"The jury was deeply impressed by Queline Meadows's inspired mix of movies, images, music and text woven into a subtle and emotionally affecting video expressing a strong sense of nostalgia and the irretrievable passage of time," said film archivist Rick Prelinger... Filmmaker Samantha Close expresses both the breadth of 1929's production and the eternal bounty of the public domain, using images from 1929's films and public domain images from elsewhere and elsewhen.
One honorable mention entry was described as "an audacious and yes, dopey exploration of the essential greatness of Internet Archive and the dread near-infinity of copyright."

Are Return-to-Office Mandates Just Attempts to Make People to Quit?
Friday on a Washington Post podcast, their columnists discussed the hybrid/remote work trend, asking why it "seems to be reversing".
Molly Roberts: Why have some companies decided finally that having offices full of employees is better for them?
Heather Long: It's a loaded question, but I would say, unfortunately, 2025 is the year of operational efficiency, and that's corporate speak for save money at all costs. How do you save money? The easiest way is to get people to quit. What are these return to office mandates, particularly the five day a week in office mandates? We have a lot of data on this now, and it shows people will quit and you don't even have to pay them severance to do it.
Molly Roberts: It's not about productivity for the people who are in the office, then, you think. It's more about just cutting down on the size of the workforce generally.
Heather Long: I do think so. There has been a decent amount of research so far on fully remote, hybrid and fully in office. It's a mixed bag for fully remote. That's why I think if you look at the Fortune 500, only about 16 companies are fully remote, but a lot of them are hybrid. The reason that so much companies are hybrid is because that's the sweet spot. There is no productivity difference between the hybrid schedule and fully in the office five days a week. But what you do see a big difference is employee satisfaction and happiness and employee retention....
I think if what we're talking about is places that have been able to do work from home successfully for the past several years, why are they suddenly in 2025, saying the whole world has changed and we need to come back to the office five days a week? You should definitely be skeptical.
"Who are the first people to leave in these scenarios? It's star employees who know they can get a job elsewhere," Long says (adding later that "There's also quantifiable data that show that, particularly parents, the childcare issues are real.") Long also point out that most of Nvidia's workforce is fully remote — and that housing prices have spiked in some areas where employers are now demanding people return to the office.
But employers also know hiring rates are now low, argues Long, so they're pushing their advantage — possibly out of some misplaced nostalgie. "[T]here's a huge, huge perception difference between what managers, particularly senior leaders in an organization, how effective they think in offices versus what the rank and file people think. Rank and file people tend to prefer hybrid because they don't want their time wasted."
Their discussion also notes a recent Harvard Business School survey that found that 40% of people would trade 5% or more of their salaries to work from home....

Donkey Kong's Famed Kill Screen Has Been Cleared For the First Time
An anonymous reader quotes a report from Ars Technica: If you watched the 2007 documentary King of Kong or followed the controversy surrounding score-chaser Billy Mitchell, you know all about Donkey Kong's famous kill screen. For over four decades, no one was able to pass the game's 117th screen (aka level 22-1) due to a glitch in the game's bonus timer that kills Mario well before he can reach the top of the stage's girders. That was true until last weekend, when Mario speedrunner Kosmic shared the news that he had passed the kill screen using a combination of frame-perfect emulator inputs, a well-known ladder movement glitch, and a bit of luck. And even though Kosmic's trick is functionally impossible to pull off with human reflexes on real hardware, the method shows how the game's seemingly insurmountable kill screen actually can be overcome without modifying the code on an official Donkey Kong arcade board.

Mysterious Radiation Belts Detected Around Earth After Epic Solar Storm
After the powerful solar storm of May 2024, scientists detected two new temporary radiation belts around Earth -- one of which contained something we had never seen before: energetic protons. ScienceAlert reports: "These are really high-energy electrons and protons that have found their way into Earth's inner magnetic environment," says astronomer David Sibeck of NASA's Goddard Space Flight Center, who was not involved with the research. "Some might stay in this place for a very long time." In fact, the belts remained intact for much longer than previous temporary radiation belts generated by solar storms: three months, compared to the weeks we'd normally expect.
Subsequent solar storms in June and August of 2024 knocked most of the particles out of orbit, significantly diminishing the density of the belts. A small amount, however, still remains up there, hanging out with Earth. What's more, the proton belt may remain intact for over a year. Ongoing measurements will help scientists measure its longevity and decay rate.
This is important information to have: particles in Earth orbit can pose a hazard to satellites hanging out up there, so knowing the particle density and the effects solar storms can have thereon can help engineers design mitigation strategies to protect our technology. At the moment, though, the hazard posed by the new radiation belts is unquantified. Future studies will be needed to determine the risks these, and future belts, might pose. The findings have been published in the Journal of Geophysical Research: Space Physics.

Quantum Teleportation Used To Distribute a Calculation
An anonymous reader quotes a report from Ars Technica: In today's issue of Nature, a team at Oxford University describes using quantum teleportation to link two pieces of quantum hardware that were located about 2 meters apart, meaning they could easily have been in different rooms entirely. Once linked, the two pieces of hardware could be treated as a single quantum computer, allowing simple algorithms to be performed that involved operations on both sides of the 2-meter gap. [...] The Oxford team was simply interested in a proof-of-concept, and so used an extremely simplified system. Each end of the 2-meter gap had a single trap holding two ions, one strontium and one calcium. The two atoms could be entangled with each other, getting them to operate as a single unit.
The calcium ion served as a local memory and was used in computations, while the strontium ion served as one of the two ends of the quantum network. An optical cable between the two ion traps allowed photons to entangle the two strontium ions, getting the whole system to operate as a single unit. The key thing about the entanglement processes used here is that a failure to entangle left the system in its original state, meaning that the researchers could simply keep trying until the qubits were entangled. The entanglement event would also lead to a photon that could be measured, allowing the team to know when success had been achieved (this sort of entanglement with a success signal is termed "heralded" by those in the field).
The researchers showed that this setup allowed them to teleport with a specific gate operation (controlled-Z), which can serve as the basis for any other two-qubit gate operation -- any operation you might want to do can be done by using a specific combination of these gates. After performing multiple rounds of these gates, the team found that the typical fidelity was in the area of 70 percent. But they also found that errors typically had nothing to do with the teleportation process and were the product of local operations at one of the two ends of the network. They suspect that using commercial hardware, which has far lower error rates, would improve things dramatically. Finally, they performed a version of Grover's algorithm, which can, with a single query, identify a single item from an arbitrarily large unordered list. The "arbitrary" aspect is set by the number of available qubits; in this case, having only two qubits, the list maxed out at four items. Still, it worked, again with a fidelity of about 70 percent.
While the work was done with trapped ions, almost every type of qubit in development can be controlled with photons, so the general approach is hardware-agnostic. And, given the sophistication of our optical hardware, it should be possible to link multiple chips at various distances, all using hardware that doesn't require the best vacuum or the lowest temperatures we can generate. That said, the error rate of the teleportation steps may still be a problem, even if it was lower than the basic hardware rate in these experiments. The fidelity there was 97 percent, which is lower than the hardware error rates of most qubits and high enough that we couldn't execute too many of these before the probability of errors gets unacceptably high.

Automakers Sue To Kill Maine's Hugely Popular 'Right To Repair' Law
Maine's overwhelmingly popular right-to-repair law is under attack by automakers through lawsuits and lobbying efforts aimed at weakening or delaying enforcement. While the law remains in limbo due to industry influence and legal challenges, broader enforcement issues persist across multiple states, with corporations often ignoring right-to-repair laws despite their legal passage. Techdirt reports: A little over a year ago, Maine residents voted overwhelmingly (83 percent) to pass a new state right to repair law designed to make auto repairs easier and more affordable. More specifically, the law requires that automakers standardize on-board diagnostic systems and provide remote access to those systems and mechanical data to consumers and third-party independent repair shops. But as we've seen with other states that have passed right to reform laws (most notably New York), passing the law isn't the end of the story. Corporate lobbyists have had great success not just watering these laws down before passage, but after voters approve them. They've also been swarmed by coordinated industry lawsuits and falsehood-spewing attacks.
Maine's popular right to repair law just took effect after a year of hashing out the fine details, but the bill's still being changed as the state tries to sort out enforcement. Large automakers have been looming over that process to try and weaken the law. But the Alliance For Automotive Innovation also just filed a new lawsuit saying the law isn't fully cooked and therefore violates the law: "This is an example of putting the cart before the horse. Before automakers can comply, the law requires the attorney general to first establish an 'independent entity' to securely administer access to vehicle data. The independent entity hasn't been established. That's not in dispute. Compliance with the law right now is not possible."

Google's 7-Year Slog To Improve Chrome Extensions Still Hasn't Satisfied Developers
The Register's Thomas Claburn reports: Google's overhaul of Chrome's extension architecture continues to pose problems for developers of ad blockers, content filters, and privacy tools. [...] While Google's desire to improve the security, privacy, and performance of the Chrome extension platform is reasonable, its approach -- which focuses on code and permissions more than human oversight -- remains a work-in-progress that has left extension developers frustrated.
Alexei Miagkov, senior staff technology at the Electronic Frontier Foundation, who oversees the organization's Privacy Badger extension, told The Register, "Making extensions under MV3 is much harder than making extensions under MV2. That's just a fact. They made things harder to build and more confusing." Miagkov said with Privacy Badger the problem has been the slowness with which Google addresses gaps in the MV3 platform. "It feels like MV3 is here and the web extensions team at Google is in no rush to fix the frayed ends, to fix what's missing or what's broken still." According to Google's documentation, "There are currently no open issues considered a critical platform gap," and various issues have been addressed through the addition of new API capabilities.
Miagkov described an unresolved problem that means Privacy Badger is unable to strip Google tracking redirects on Google sites. "We can't do it the correct way because when Google engineers design the [chrome.declarativeNetRequest API], they fail to think of this scenario," he said. "We can do a redirect to get rid of the tracking, but it ends up being a broken redirect for a lot of URLs. Basically, if the URL has any kind of query string parameters -- the question mark and anything beyond that -- we will break the link." Miagkov said a Chrome developer relations engineer had helped identify a workaround, but it's not great. Miagkov thinks these problems are of Google's own making -- the company changed the rules and has been slow to write the new ones. "It was completely predictable because they moved the ability to fix things from extensions to themselves," he said. "And now they need to fix things and they're not doing it."

OpenAI Investigating Claim of 20 Million Stolen User Credentials
OpenAI says it's investigating after a hacker claimed to have stolen login credentials for 20 million OpenAI accounts and advertised the data for sale on a dark web forum. Though security researchers doubt on the legitimacy of the breach, the AI company stated that it takes the claims seriously, advising users to enable two-factor authentication and stay vigilant against phishing attempts. Decrypt reports: Daily Dot reporter Mikael Thalan wrote on X that he found invalid email addresses in the supposed sample data: "No evidence (suggests) this alleged OpenAI breach is legitimate. At least two addresses were invalid. The user's only other post on the forum is for a stealer log. Thread has since been deleted as well."
"We take these claims seriously," the spokesperson said, adding: "We have not seen any evidence that this is connected to a compromise of OpenAI systems to date."

US Health System Notifies 882,000 Patients of August 2023 Breach
An anonymous reader quotes a report from BleepingComputer: Hospital Sisters Health System notified over 882,000 patients that an August 2023 cyberattack led to a data breach that exposed their personal and health information. Established in 1875, HSHS works with over 2,200 physicians and has around 12,000 employees. It also operates a network of physician practices and 15 local hospitals across Illinois and Wisconsin, including two children's hospitals. The non-profit healthcare system said in data breach notifications sent to those impacted that the incident was discovered on August 27, 2023, after detecting that the attacker had gained access to HSHS' network.
After the security breach, its systems were also impacted by a widespread outage that took down "virtually all operating systems" and phone systems across Illinois and Wisconsin hospitals. HSHS also hired external security experts to investigate the attack, assess its impact, and help its IT team restore affected systems. [...] While the incident and the resulting outage have all the signs of a ransomware attack, no ransomware operation has claimed the breach. Following the forensic investigation, HSHS found that the attackers had accessed files on compromised systems between August 16 and August 27, 2023.
The information accessed by the threat actors while inside HSHS' systems varies for each impacted individual, and it includes a combination of name, address, date of birth, medical record number, limited treatment information, health insurance information, Social Security number, and/or driver's license number. While HSHS added that there is no evidence that the victims' information has been used in fraud or identity theft attempts, it warned affected individuals to monitor their account statements and credit reports for suspicious activity. The health system also offers those affected by the breach one year of free Equifax credit monitoring.
