Nuclear fusion — which releases four times the energy of fission — could theoretically happen sooner in space than on earth, reports CNN.

"And it could help spacecraft achieve speeds of up to 500,000 miles (805,000 kilometers) per hour — more than the fastest object ever built..." With funding from the UK Space Agency, British startup Pulsar Fusion has unveiled Sunbird, a space rocket concept designed to meet spacecraft in orbit, attach to them, and carry them to their destination at breakneck speed using nuclear fusion... For now, Sunbird is in the very early stages of construction and it has exceptional engineering challenges to overcome, but Pulsar says it hopes to achieve fusion in orbit for the first time in 2027. [Pulsar's founder/CEO says the first functional Sunbird would be ready four to five years later.]

If the rocket ever becomes operational, it could one day cut the journey time of a potential mission to Mars in half.
CNN says the proposed Sunbird process would use helium-3 — which may be abundant on the Moon — to generate protons which "can be used as a 'nuclear exhaust' to provide propulsion". (And without generating any dangerous radioactive material.) "It's very unnatural to do fusion on Earth," says Richard Dinan, founder and CEO of Pulsar. "Fusion doesn't want to work in an atmosphere. Space is a far more logical, sensible place to do fusion, because that's where it wants to happen anyway...."

Sunbirds would operate similarly to city bikes at docking stations, according to Dinan: "We launch them into space, and we would have a charging station where they could sit and then meet your ship," he says. "You turn off your inefficient combustion engines, and use nuclear fusion for the greater part of your journey. Ideally, you'd have a station somewhere near Mars, and you'd have a station on low Earth orbit, and the (Sunbirds) would just go back and forth...." Initially, the Sunbirds will be offered for shuttling satellites in orbit, but their true potential would come into play with interplanetary missions. The company illustrates a few examples of the missions that Sunbird could unlock, such as delivering up to 2,000 kilograms (4,400 pounds) of cargo to Mars in under six months, deploying probes to Jupiter or Saturn in two to four years (NASA's Europa Clipper, launched in 2024 towards one of Jupiter's moons, will arrive after 5.5 years), and an asteroid mining mission that would complete a round trip to a near-Earth asteroid in one to two years instead of three.

Other companies are working on nuclear fusion engines for space propulsion, including Pasadena-based Helicity Space, which received investment from aerospace giant Lockheed Martin in 2024. San Diego-based General Atomics and NASA are working on another type of nuclear reactor — based on fission rather than fusion — which they plan to test in space in 2027.

A SpaceX Falcon 9 rocket launched a four-member crew to the International Space Station on Friday night, paving the way for NASA astronauts Butch Wilmore and Suni Williams to return to Earth after being there for nine months due to issues with Boeing's Starliner capsule. Arrival is set for late Saturday night. The Associated Press reports: NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting. The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Reaching orbit from NASA's Kennedy Space Center, the newest crew includes NASA's Anne McClain and Nichole Ayers, both military pilots; and Japan's Takuya Onishi and Russia's Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free. "Spaceflight is tough, but humans are tougher," McClain said minutes into the flight. You can watch a recording of the launch here.

Wilmore and Williams aren't stranded on the International Space Station, and they weren't abandoned, the astronauts reminded CNN in a rare space-to-earth interview last month. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..."

European nations have heightened security after a series of suspected sabotage attacks on submarine infrastructure in the Baltic Sea, with officials increasingly pointing to Russia as the likely culprit.

Finnish authorities detained the tanker Eagle S in December after it allegedly damaged three undersea fiber-optic connections with Estonia and one with Germany. The vessel, carrying Russian oil as part of a "shadow fleet" evading sanctions, made suspicious course changes while crossing cable routes.

In November, two more submarine cables in the Baltic were damaged, with investigations focusing on Chinese-owned cargo ship Yi Peng 3, which reduced speed near the cables and turned off its transponder. NATO launched Baltic Sentry in January to enhance surveillance, deploying ships and naval drones off Estonia's coast. The alliance also established a coordination cell following the 2022 Nord Stream pipeline sabotage.

Russia has denied involvement, accusing NATO of using "myths" to increase its Baltic presence.

AT&T and Verizon have successfully completed their first cellphone-to-satellite video calls using AST SpaceMobile's satellites, marking a significant step toward commercial satellite networks. The Verge reports: Verizon has completed its first cellphone-to-satellite video call, while AT&T has completed its first using satellites that will be used as part of a commercial network. [...] Verizon pulled off "a live video call between two mobile devices with one connected via satellite and the other connected via Verizon's terrestrial network connection," according to a company press release.

In AT&T's case, "AT&T and AST SpaceMobile have successfully completed another video call by satellite to an everyday smartphone over AT&T spectrum," per AT&T's press release. Both phone companies relied on AST's constellation of five BlueBird satellites that were launched last September for the tests. AT&T's initial video call test happened in June 2023.

Today 34-year-old chess champion Magnus Carlsen married 26-year-old Ella Victoria Malone, "in a ceremony packed with guests on a sunny winter day in Oslo," reports Chess.com. According to Norwegian newspaper Dagbladet, a film crew from Netflix was also present. The streaming giant is shooting a chess-related TV show rumored to air in 2025... Ella Victoria is now expected to have a more central role in her husband's career. According to VG, she played a crucial role in securing Magnus a deal with fashion brand G-Star Raw...

Their wedding was surely a fairy tale, but the Carlsens aren't heading for their honeymoon just yet. Magnus is set to make his debut for St. Pauli in the German Bundesliga on January 10, when he'll face Dusseldorf led by none other than GM Gukesh Dommaraju.
The article adds that "For Carlsen, this caps off a whirlwind week that began in New York, highlighted by his eighth World Blitz Championship title," a victory that they say was "controversially" shared with Russian grandmaster Ian Nepomniachtchi. CNN reports: [Carlsen] had taken a 2-0 lead in the four-game contest before Nepomniachtchi launched a stunning comeback to level the scores, sending the match to a sudden death tie-break. The pair then drew the next three games, and it was later determined that they would share the title after the proposal was accepted by Arkady Dvorkovich, the president of chess governing body FIDE. "I thought, at that point, we had already played for a very long time and I was, first of all, very happy to end it, and I thought, at that point, it would have been very, very cruel on both of us if one gets first and the other gets second," Carlsen later told reporters....

[T]he decision to share the Blitz title with long-time rival Nepomniachtchi has sparked outcry from some of the world's top players — the first time in history that a world championship title has been shared. "This is a situation where I cannot stand with what Magnus has done," prominent player Hikaru Nakamura said on his YouTube channel. "I do not think that there is any precedent for this, when you put out rules about the game itself and then suddenly you decide, 'It's okay, we're going to go home' ... It's unconscionable to me...."

"FIDE goes from forfeiting Carlsen (over the jeans debacle) to creating an entirely new rule," Hans Niemann, whom Carlsen had defeated in the quarterfinals, wrote on X, formerly known as Twitter. "Seems like the the regulatory body of chess has no intention of being unbiased. They seem to only care about what one player thinks...." Former world champion Garry Kasparov made a pointed reference to the jeans controversy, writing on X: "I thought the first FIDE tiebreak was pants."
Magnus apparently tells his opponent "If they like refuse, we can just play short draws until they give up," according to a behind-the-scenes video clip posted to X.com. The CEO of FIDE, Emil Sutovsky, re-posted it on X.com, complaining that FIDE president Dvorkovich's decision to accept the players' proposed draw was made "under the spur of a moment, and of course, the video appeared much later. I do think it is VERY BAD though..."

FIDE later told CNN that "This situation has already prompted valuable discussions within FIDE management to improve our regulations." (And their article adds that some — including grandmaster Ivan Sokolov — suggested ties be settled with a new chess format known as Armageddon.) "In Armageddon, White has more time but a draw on the board counts as a win for Black," explains the Guardian — adding that back in 1983, "Fide determined the winner of a Candidates match by a roulette wheel."

The Guardian adds that Russian-born FIDE president Arkady Dvorkovich "probably felt he had little choice but to rubber stamp the agreement by the players." He would have been pilloried in Moscow as preventing a Russian world champion had he ruled otherwise, and a negative could also have provoked a series of the notorious Berlin draws, the standard method for a quick mutually agreed half point. However, that course of action would have brought the players into disrepute, and it is more likely that an inspired game or a blunder would have settled the final. The audience on Wall Street applauded the decision, but the considerable online reaction from professional players and fans has been mostly critical.

It was the first ever shared over-the-board individual world title in chess history.

25 years ago today, the late, great Suck.com played a prank on Slashdot. Their daily column of pop-culture criticism was replaced by... Suckdot, a parody site satirically filled with Slashdot-style headlines like "Linux Possibly Defamed Somewhere." RabidZelot was one of a bunch to report: "In Richmond, California, this afternoon, this dude said something bad about Linux at the Hilltop Mall near the fountains right after the first showing of Phantom Menace let out. He was last seen heading towards Sears and has a 'Where Do You Want to Go Today?' T-shirt and brown hair. Let us know when you spot him."

There's more Slashdot-style news blurbs like "Red Hat Reports Income". (In which Red Hat founder Bob Young finds a quarter on the way to the conference room, and adds it to the company's balance sheet...) Its list of user-submitted "Ask Suckdot" questions include geek-mocking topics like "Is Overclocking Worth That Burning Smell?" and "HOW DO I TURN OFF SHIFT_LOCK?" And somewhere there's even a parody of Jon Katz (an early contributor to Slashdot's content) — though clicking "Read More" on the essay leads to a surprising message from the parodist admitting defeat. "Slashdot has roughly 60 million links on its front page. I'm simply not going to waste any more of my life making fun of each and every one of them. Half the time you can't tell the real Slashdot from the parody anyway."

Suck.com was a fixture in the early days of the web, launched in 1995 (and pre-dating the launch of Slashdot by two years). It normally published link-heavy commentary every weekday for nearly six years. Contributing writer Greg Knauss was apparently behind much of the Suckdot parody — even taking a jab at Slashdot's early online podcast, "Geeks in Space" (1999-2001). [Suckdot informs its readers in 1999 that "The latest installment of Geeks Jabbering at a Mic is up..."] Other Suckdot headlines?

• Minneapolis-St. Paul Star-Tribune Uses Words "Red" and "Hat" in Article
• BSD Repeatedly Ignored

• iMac: Ha Ha Ha Ha Wimp

There were no hard feelings. Seven months later Slashdot was even linking to Greg Knauss's Suck.com essay proclaiming that "Mozilla is dead, or might as well be..."

So whatever happened to Suck.com? Though it stopped publishing in 2001, an outpouring of nostalgia in 2005 apparently prompted its owners at Lycos.com to continue hosting its content through 2018. (This unofficial history notes that one fan scrambling to archive the site was Aaron Swartz.) Though it's not clear what happened next, here in 2024 its original domain is now up for sale — at an asking price of $1 million.

But all of Suck.com's original content is still available online — including its Suckdot parody — at archive.org. Which, mercifully, is still here a full 28 years after launching in 1996...

This week a Florida-based Bitcoin-tech company named MARA Holdings announced it had bought a 114-megawatt Texas wind farm, reports Chron.com, "and will subsequently take it off the power grid and use it to energize its mining operations."

MARA's CEO tells the site they're "leveraging renewable resources that would have otherwise been curtailed" while "reducing our bitcoin production costs through vertical integration, and demonstrating MARA's commitment to environmental stewardship." The wind farms were not a part of the Electric Reliability Council of Texas (ERCOT) grid, but instead they were located within the Southwest Power Pool, which manages the market for the central U.S., including but not limited to most or parts of Oklahoma, Kansas, Nebraska, South Dakota and North Dakota... A 114-MW facility could power somewhere between 20,000 and 100,000 homes, depending on who you ask...

Historically, the facilities use up a lot of power and have generated backlash from neighbors who have complained about the noise of the machines inside. Texas has been a haven for cryptocurrency tech companies, primarily because of the state's space, deregulated power market and friendly business climate. Two weeks ago, the Public Utilities Commission adopted a rule requiring crypto and other virtual currency miners within the ERCOT grid to register their locations, ownership information and electricity demands, to further ensure that they could be watchful of this emerging source of energy consumption.
"Crypto mining operations currently consume around 2.3 percent of US electricity, and it requires roughly 155,000kWh to mine one Bitcoin," notes the site Data Centre Dynamics. This is the second off-grid power deal MARA has signed over the last few months. In October, it launched a 25MW micro data center operation across oil wellheads in Texas and North Dakota. The data center will be powered exclusively by excess natural gas from oilfield production that would have otherwise been flared. The operation will be distributed across wellheads in Texas and North Dakota, with operational status expected by January 2025.
Some context from Bloomberg: A few years ago Bitcoin miners took part in a global scramble for electricity to power their specialized computers... But the rise of AI, with its insatiable demand for electricity, dwarfed the needs of crypto and upended energy markets worldwide. Miners must now compete with much-larger tech firms for connections to electrical grids and power contracts. "Bitcoin miners are being forced to go look at marginal generation," said [MARA CEO Fred] Thiel. "The AI guys can afford to pay a much higher amount for energy than a Bitcoin miner"... MARA's plan to mine only when the wind is blowing makes economic sense because its mine will house last-generation computers that would otherwise have been retired, Thiel said.
"Thiel said he'd be interested to potentially buy more wind farms over time."

An anonymous reader quotes a report from PCMag: Have I Been Pwned has long been one of the most useful ways to learn if your personal information was exposed in a hack. But a new site offers its own powerful tool to help you check if your data has been leaked to cybercriminals. DataBreach.com is the work of a New Jersey company called Atlas Privacy, which helps consumers remove their personal information from data brokers and people search websites. On Wednesday, the company told us it had launched DataBreach.com as an alternative to Have I Been Pwned, which is mainly searchable via the user's email address. DataBreach.com is designed to do that and more. In addition to your email address, the site features an advanced search function to see whether your full name, physical address, phone number, Social Security number, IP address, or username are in Atlas Privacy's extensive library of recorded breaches. More categories will also be added over time.

Atlas Privacy has been offering its paid services to customers, such as police officers and celebrities, to protect bad actors from learning their addresses or phone numbers. In doing so, the company has also amassed over 17.5 billion records from the numerous stolen databases circulating on the internet, including in cybercriminal forums. As a public service, Atlas is now using its growing repository of stolen records to create a breach notification site, free of charge. DataBreach.com builds off Atlas's effort in August to host a site notifying users whether their Social Security number and other personal information were leaked in the National Public Data hack. Importantly, Atlas designed DataBreach.com to prevent it from storing or collecting any sensitive user information typed into the site. Instead, the site will fetch a hash from Atlas' servers, or a fingerprint of the user's personal information -- whether it be an email address, name, or SSN -- and compare it to whatever the user is searching for. "The comparison will be done locally," meaning it'll occur on the user's PC or phone, rather than Atlas's internet server, de Saint Meloir said.

Notorious for a hardworking culture, Japan launched an initiative to help people cut back. But three years into the effort, the country is having a hard time coaxing people to take a four-day workweek. From a report: Japanese lawmakers first proposed a shorter work week in 2021. The guidelines aimed to encourage staff retention and cut the number of workers falling ill or dying from overwork in an economy already suffering from a huge labor shortage. The guidelines also included overtime limits and paid annual leave. However, the initiative has had a slow start: According to the Ministry of Health, Labor, and Welfare, only about 8% of companies in Japan allow employees to take three or more days off a week.

It's not just companies -- employees are hesitant, too. Electronics manufacturer Panasonic, one of Japan's largest companies, opted into the effort in early 2022. Over two years in, only 150 of its 63,000 eligible employees have chosen to take up four-day schedules, a representative of the company told the Associated Press. Other major companies to introduce a four-day workweek include Uniqlo parent Fast Retailing, electronics giant Hitachi, and financial firm Mizuho. About 85% of employers report giving workers the usual two days off a week. Much of the reluctance to take an extra day off boils down to a culture of workers putting companies before themselves, including pressure to appear like team players and hard workers. This intense culture stems from Japan's postwar era, where, in an effort to boost the economy, then-Prime Minister Shigeru Yoshida enlisted major corporations to offer their employees lifelong job security, asking only that workers repay them with loyalty.

Pundits aggregate results from multiple pollsters to minimize biases. So ZDNet tried the same approach, but aggregating rankings for the popularity of 19 top programming languages. Senior contributing editor David Gewirtz combined results from nine popularity rankings, including PYPL, the Tiobe index, GitHub's Usage 2023 summary report, and several rankings from Stack Overflow and from IEEE Spectrum.

The results? The top cluster contains Python, JavaScript, and Java. These are all very representative in the world of AI coding...

The next cluster contains the classic C-based languages [C++, C#, C], plus TypeScript (which is a more robust JavaScript variant) and SQL.

Below that are languages that were dominant a while ago, the web languages used to build and operate websites [HTML/CSS, PHP, Shell], followed by a range of other languages that are either growing in popularity (R, Dart) or dropping in popularity (Ruby). [Just above Ruby are Go, Rust, Kotlin, and Lua.]

Finally, at the bottom is Swift, Apple's language of choice. Objective-C, the previous language of Apple programming, has all but dropped off the list since Apple launched Swift. But while Apple boasts many developers, Swift is clearly not a standout in programmer interest... [T]here aren't a huge number of companies hiring Apple app developers, at least primarily. That's why Swift is relatively far down the chart. Objective-C is being replaced by Swift, and we can see it dropping right before our eyes.
"With the exception of Java, the C-family of languages still dominates," the article concludes, before adding that if you're only going to learn one language, "I'd recommend Python, Java, and JavaScript instead." But it also advises aspiring programmers to learn "multiple languages and multiple frameworks. Build things in the languages. Programming is not just an intellectual exercise. You have to actually make stuff....

"[L]earning how to learn languages is as important as learning a language — and the best way to do that is to learn more than one."

Scientists have finally detected and measured the ambipolar field, a weak electric field surrounding Earth that was first theorized over 60 years ago. "Any planet with an atmosphere should have an ambipolar field," says astronomer Glyn Collinson of NASA's Goddard Space Flight Center. "Now that we've finally measured it, we can begin learning how it's shaped our planet as well as others over time." ScienceAlert reports: Here's how the ambipolar field was expected to work. Starting at an altitude of around 250 kilometers (155 miles), in a layer of the atmosphere called the ionosphere, extreme ultraviolet and solar radiation ionizes atmospheric atoms, breaking off negatively charged electrons and turning the atom into a positively charged ion. The lighter electrons will try to fly off into space, while the heavier ions will try to sink towards the ground. But the plasma environment will try to maintain charge neutrality, which results in the emergence of an electric field between the electrons and the ions to tether them together. This is called the ambipolar field because it works in both directions, with the ions supplying a downward pull and the electrons an upward one. The result is that the atmosphere is puffed up; the increased altitude allows some ions to escape into space, which is what we see in the polar wind.

This ambipolar field would be incredibly weak, which is why Collinson and his team designed instrumentation to detect it. The Endurance mission, carrying this experiment, was launched in May 2022, reaching an altitude of 768.03 kilometers (477.23 miles) before falling back to Earth with its precious, hard-won data. And it succeeded. It measured a change in electric potential of just 0.55 volts -- but that was all that was needed. "A half a volt is almost nothing -- it's only about as strong as a watch battery," Collinson says. "But that's just the right amount to explain the polar wind." That amount of charge is enough to tug on hydrogen ions with 10.6 times the strength of gravity, launching them into space at the supersonic speeds measured over Earth's poles. Oxygen ions, which are heavier than hydrogen ions, are also lofted higher, increasing the density of the ionosphere at high altitudes by 271 percent, compared to what its density would be without the ambipolar field. The findings have been published in the journal Nature.

The Wall Street Journal visits scientists at Harvard University's Wyss Institute for Biologically Inspired Engineering who are researching a "sugar-to-fiber" enzyme (normally used by plants to create stalks). They're testing a version they've "encased in spherical nanoparticles — tiny mesh-like cages made of pectin that allow the enzyme to be added to food without being activated until it reaches the intestine.

"Once there, a change in pH causes the cage to expand, freeing the enzyme to float through its holes and start converting sugar to fiber." The Wyss Institute's goal for its enzyme product was to reduce the sugar absorbed from food by 30%, though it has the potential to remove even more than that, says Sam Inverso, director of business development partnerships at the Wyss Institute. The enzyme's ability to turn sugar into fiber is also key, as most Americans don't get nearly enough fiber in their diet, says Adama Sesay, a senior engineer at the Wyss Institute who worked on the project...

The Wyss Institute is now licensing the technology to a company to help bring its enzyme product to market, a process that entails additional testing and work to secure regulatory approval. Inverso says that the aim is for the product to be available to U.S. food manufacturers within the next two years, and that other encapsulated enzymes could follow: products that reduce lactose absorption after drinking milk, or cut gluten after eating bread. For now the enzyme works better in solid food than in a liquid. Producing it in large quantities and at low cost is still a ways off — currently it's 100 times more expensive than raw sugar, Inverso says.
And the Journal notes they're not the only ones working on the problem: San Francisco-based startup Biolumen recently launched a product called Monch Monch, a drink mix made of fibrous, microscopic sponges designed to soak up sugar and prevent it from reaching the bloodstream. At mealtime consumers can blend a teaspoon of Monch Monch, which has no taste, smell or color, into drinks from water to wine. Once it has reached the stomach, the sponges start to swell and sequester sugar, reducing its burden on the body, says Dr. Robert Lustig, Biolumen's co-founder and chief medical officer... One gram of Monch Monch can sequester six grams of sugar, says Lustig... The product, introduced as a dietary supplement, can also be used as a food ingredient under a Food and Drug Administration principle known as "generally recognized as safe." Packets of Monch Monch are available for purchase online, and Biolumen says it is in talks with U.S. food manufacturers it declined to name about its use in other products...

Food companies are betting on other solutions for now. Cereal startup Magic Spoon uses allulose, a natural sugar found in figs and raisins that is growing in popularity, helped by FDA guidance that allows it to be excluded from sugar or added-sugar totals on nutrition labels. Ingredient company Tate & Lyle, which makes allulose from corn kernels, says the sweetener tastes like sugar and adds bulk and caramel color, but passes through the body without being metabolized... Chicago-based Blommer Chocolate recently launched a line of reduced-sugar chocolate and confectionery products made with Incredo, a sugar that has been physically altered to taste sweeter using a mineral carrier that dissolves faster in saliva and targets the sweet-taste receptors on the tongue. Incredo's use enables manufacturers to use up to 50% less sugar, the company says.
The article even notes that "researchers still working to reduce sugar are peddling new technologies, like individual sugar crystals modified to dissolve more quickly in the mouth, making food taste sweeter."

Longtime Slashdot reader schwit1 shares a report from Ars Technica: The upper stage from a Chinese rocket that launched a batch of Internet satellites Tuesday has broken apart in space, creating a debris field of at least 700 objects in one of the most heavily-trafficked zones in low-Earth orbit. US Space Command, which tracks objects in orbit with a network of radars and optical sensors, confirmed the rocket breakup Thursday. Space Command initially said the event created more than 300 pieces of trackable debris. The military's ground-based radars are capable of tracking objects larger than 10 centimeters (4 inches). Later Thursday, LeoLabs, a commercial space situational awareness company, said its radars detected at least 700 objects attributed to the Chinese rocket. The number of debris fragments could rise to more than 900, LeoLabs said. The culprit is the second stage of China's Long March 6A rocket, which lifted off Tuesday with the first batch of 18 satellites for a planned Chinese megaconstellation that could eventually number thousands of spacecraft. The Long March 6A's second stage apparently disintegrated after placing its payload of 18 satellites into a polar orbit.

Space Command said in a statement it has "observed no immediate threats" and "continues to conduct routine conjunction assessments to support the safety and sustainability of the space domain." According to LeoLabs, radar data indicated the rocket broke apart at an altitude of 503 miles (810 kilometers) at approximately 4:10 pm EDT (20:10 UTC) on Tuesday, around 13-and-a-half hours after it lifted off from northern China. At this altitude, it will take decades or centuries for the wispy effect of aerodynamic drag to pull the debris back into the atmosphere. As the objects drift lower, their orbits will cross paths with SpaceX's Starlink Internet satellites, the International Space Station and other crew spacecraft, and thousands more pieces of orbital debris, putting commercial and government satellites at risk of collision.

An anonymous reader quotes a report originally published by Business Insider: A Chinese state-backed company has launched its first 18 satellites in its bid to build a vast orbital network aimed at rivaling Starlink, according to local media. The launch on Monday by Shanghai Spacecom Satellite Technology involved 18 satellites and one rocket, per The China Securities Journal, which is run by state news agency Xinhua. According to the outlet, the rocket lifted off from the Taiyuan satellite and missile launch center in Shanxi province.

These satellites mark the first step in the company's effort to create a 15,000-strong network of Low Earth Orbit satellites, which the firm has dubbed the "Thousand Sails Constellation." The company said it plans to reach that final tally by 2030, per The China Securities Journal. Domestic media has widely called the project the Chinese version of Starlink, which runs about 6,000 satellites. Elon Musk has said that he plans to eventually host a network of 42,000 satellites.

The Thousand Sails Constellation, also known as the G60 project, is one of three planned major satellite networks in the country. Each is expected to field 10,000 or more satellites. Most are anticipated to orbit between 200 and 1,200 miles above the Earth's surface, which is also where Starlink satellites are generally found. The three constellations, along with dozens of ambitious space projects from other Chinese firms, have been fueled by a recent push from the central government to loop the private sector into its science and technology goals.

Canned water distilled from the air will be available to buy in the US later this year, in an effort to promote solar-powered "hydropanels" that provide an off-grid method of producing drinking water. New Scientist adds: The panels, created by Arizona-based firm Source, use solar energy to power fans, which draw water vapour from the air. A water-absorbing substance, known as a desiccant, traps the moisture, before solar energy from the panel releases the moisture into a collection area within the panel. The distilled water is then sent to a pressurised tank, where the pH is tweaked and minerals like calcium and magnesium are added.

Each panel can produce up to 3 litres of drinking water water a day, about the average daily intake for one person. The process works effectively even in hot, arid conditions such as Arizona, says Friesen. Source, which launched in 2014 as Zero Mass Water, already has hydropanels installed in 56 countries around the world. The panels can be installed as ground arrays, or on rooftops, linked into a building's drinking water pipes. Many sites serve off-grid communities without easy access to potable water, says Friesen. Most of the panels, which retail at almost $3000 apiece, are purchased by governments or development banks, although households can also install panels privately.

"Virgin Galactic launched six people to suborbital space on Saturday, launching a Turkish astronaut and three space tourists," reports Space.com, "on what was the final voyage of the VSS Unity space plane." Unity, attached to the belly of its carrier plane Eve, took off from runway at Spaceport America in New Mexico at 10:31 a.m. EDT (1431 GMT) and carried to an altitude of 44,562 feet (13,582 meters) over the next hour, where it was dropped and ignited its rocket engine to carry two pilots and four passengers to space and back. The mission, called Galactic 07, reached an altitude of 54.4 miles (87.5 km) and marked the seventh commercial spaceflight by Virgin Galactic on Unity, which is being retired to make way for the company's new "Delta" class of spacecraft rolling out in 2026.

"I will need much more time to try and process what just happened," Tuva Atasever, the Turkish Space Agency astronaut on the flight, said in a post-flight press conference, adding that the view of Earth was indescribable. "It's not something you can describe with adjectives. It's an experiential thing ... you just feel it in your gut."
One of the space tourists was a principal propulsion engineer at SpaceX, who wore the flags of the U.S. and India on his spacesuit to honor both his home country and that of his parents. The other two were a New York-based real estate developer and a London-based hotel and resort investment strategy advisor.

The flight landed 70 minutes later at 11:41 a.m. EDT (1541 GMT), according to the article, "marking only its seventh commercial spaceflight for Virgin Galactic and 12th crewed spaceflight overall." In all, Virgin Galactic flew the space plane just 32 times, including non-space test flights... "This vehicle was revolutionary," Virgin Galactic president Mike Moses said in the post-launch press conference. "We tested it, we flew it, we demonstrated and prove to the world that commercial human spaceflight is possible with private funding for private companies... Seven commercial space flights, a single vehicle flying six times in six months last year, that's groundbreaking," Moses said. "The fact that we can take this vehicle back to back to back on a monthly basis is is really revolutionary."

The new Delta class of spacecraft will be able to fly at least twice a week, about eight times the rate of SpaceShipTwo, with Virgin Galactic planning to build at least two to start its new fleet. "We're going to field in 2026 two spaceships, our mothership Eve, that's 750 astronauts a year going to space," Moses said of the new fleet's flight capacity. "That's more than have gotten to space in the 60 year history of spaceflight to date...."

Since 2018, Virgin Galactic has flown payloads as part of NASA's Flight Opportunities program and most recently was selected to be a contracted flight provider for NASA for the next five years.
Phys.org reports that with the Delta-class rockets, "The future of the company is at stake as it seeks at long last to get into the black. Virgin is burning through cash, losing more than $100 million in each of the past two quarters, with its reserves standing at $867 million at the end of March." It also laid off 185 people, or 18 percent of its workforce, late last year. Its shares are currently trading at 85 cents, down from $55 in 2021, the year Branson himself flew, garnering global headlines.
Saturday's flight also became "a suborbital science lab" for microgravity research, according to a statement from the company. Phys.org reports that during the flight, astronaut Atasever "wore custom headgear with brain activity monitoring sensors to collect physiological data, a dosimeter, and two commercially available insulin pens to examine the ability to administer accurate insulin doses in microgravity, Virgin said in a statement." And Virgin Galactic said their flight also carried "rack-mounted" autonomous payloads from both Purdue ("to study propellant slosh in fuel tanks of maneuvering spacecraf") and U.C. Berkeley ("testing a new type of 3D printing"), as well as "multiple human-tended experiments." "Discovery and innovation are central to our mission at Virgin Galactic," said Michael Colglazier, CEO of Virgin Galactic. "We're excited to build on our successful record of facilitating scientific experiments in suborbital space, and we look forward to continuing to expand our role in suborbital research going forward."

Nashville-based Yoshi Mobility launched in 2015 to deliver gasoline to vehicle owners, reports Forbes. But this week the company announced they'll begin converting GM electric delivery vans into "mobile EV superchargers" — fast, battery-powered 240 kw DC chargers — for corporate fleets of electric cars. "There's kind of this critical grid problem and so we think that we can accelerate towards an EV future and this is a unique way that we can do it," said [cofounder/CEO Bryan] Frist in an interview. "The mobile charger can charge and then it can multiplex all the spots. So we tell people, it can electrify every spot in your parking lot."

Each mobile supercharger can service between five and seven vehicles according to Frist. With perhaps two superchargers operating on a fleet operator's lot, one would service a vehicle while the other supercharger would replenish its own charge off the grid and they would alternate, according to Frist. "What we say is we can do that same charge instead of three and a half hours, we can do in 10 minutes, and we can move around your lot," Frist says. "You don't have to put in all the infrastructure. You don't have to build it out. You just contract with us."

The company plans to begin with a "handful" of mobile superchargers in [GM's] BrightDrop vans but expects to ramp up production and begin commercializing more widely during the first quarter of 2025... The mobile superchargers will complement Yoshi Mobility's existing offering of high-capacity mobile generators that sit on a fleet operator's lot putting out as much as a megawatt of power and can service a larger number of vehicles than the mobile units.

An anonymous reader quotes a report from Ars Technica: If you're tired of Google's AI Overview extracting all value from the web while also telling people to eat glue or run with scissors, you can turn it off -- sort of. Google has been telling people its AI box at the top of search results is the future, and you can't turn it off, but that ignores how Google search works: A lot of options are powered by URL parameters. That means you can turn off AI search with this one simple trick! (Sorry.) Our method for killing AI search is defaulting to the new "web" search filter, which Google recently launched as a way to search the web without Google's alpha-quality AI junk. It's actually pretty nice, showing only the traditional 10 blue links, giving you a clean (well, other than the ads), uncluttered results page that looks like it's from 2011. Sadly, Google's UI doesn't have a way to make "web" search the default, and switching to it means digging through the "more" options drop-down after you do a search, so it's a few clicks deep.

Check out the URL after you do a search, and you'll see a mile-long URL full of esoteric tracking information and mode information. We'll put each search result URL parameter on a new line so the URL is somewhat readable [...]. Most of these only mean something to Google's internal tracking system, but that "&udm=14" line is the one that will put you in a web search. Tack it on to the end of a normal search, and you'll be booted into the clean 10 blue links interface. While Google might not let you set this as a default, if you have a way to automatically edit the Google search URL, you can create your own defaults. One way to edit the search URL is a proxy site like udm14.com, which is probably the biggest site out there popularizing this technique. A proxy site could, if it wanted to, read all your search result queries, though (your query is also in the URL), so whether you trust this site is up to you.

Economist: What is the ideal job to outsource to AI? Today's AIs, in particular the Chatgpt-like generative sort, have a leaky memory, cannot handle physical objects and are worse than humans at interacting with humans. Where they excel is in manipulating numbers and symbols, especially within well-defined tasks such as writing bits of computer code. This happens to be the forte of giant existing outsourcing businesses -- India's information-technology companies. Seven of them, including the two biggest, Tata Consultancy Services (TCS) and Infosys, collectively laid off 75,000 employees last year. The firms say this reduction, equivalent to about 4% of their combined workforce, has nothing to do with ai and reflects the broader slowdown in the tech sector. In reality, they say, ai is an opportunity, not a threat.

Business services are critical to India's economy. The sector employs 5m people, or less than 1% of Indian workers, but contributes 7% of GDP and nearly a quarter of total exports. Simple services such as call centres account for a fifth of those foreign revenues. Three-fifths are generated by it services such as moving data to the computing cloud. The rest comes from sophisticated processes tailored for individual clients. Capital Economics, a research firm, calculates that an extreme case, in which ai wiped out the industry entirely and the resources were not reallocated, would knock nearly one percentage point off annual GDP growth over the next decade in India. In a likelier scenario of "a slow demise," the country would grow 0.3-0.4 percentage points less fast. The simplest jobs are the most vulnerable. Data from Upwork, a freelancing platform, shows that earnings for uncomplicated writing tasks like copy-editing fell by 5% between Chatgpt's launch in November 2022 and April 2023, relative to roles less affected by ai. In the year after Dall-e 2, an image-creation model, was launched in April 2022, wages for jobs like graphic design fell by 7-14%. Some companies are using AI to deal with simple customer-service requests and repetitive data-processing tasks. In April K. Krithivasan, chief executive of TCS, predicted that "maybe a year or so down the line" chatbots could do much of the work of a call-centre employee. In time, he mused, AI could foretell gripes and alleviate them before a customer ever picks up the phone.

An anonymous reader quotes a report from The Atlantic: In October 2003, Mark Zuckerberg created his first viral site: not Facebook, but FaceMash. Then a college freshman, he hacked into Harvard's online dorm directories, gathered a massive collection of students' headshots, and used them to create a website on which Harvard students could rate classmates by their attractiveness, literally and figuratively head-to-head. The site, a mean-spirited prank recounted in the opening scene of The Social Network, got so much traction so quickly that Harvard shut down his internet access within hours. The math that powered FaceMash -- and, by extension, set Zuckerberg on the path to building the world's dominant social-media empire -- was reportedly, of all things, a formula for ranking chess players: the Elo system.

Fundamentally, what an Elo rating does is predict the outcome of chess matches by assigning every player a number that fluctuates based purely on performance. If you beat a slightly higher-ranked player, your rating goes up a little, but if you beat a much higher-ranked player, your rating goes up a lot (and theirs, conversely, goes down a lot). The higher the rating, the more matches you should win. That is what Elo was designed for, at least. FaceMash and Zuckerberg aside, people have deployed Elo ratings for many sports -- soccer, football, basketball -- and for domains as varied as dating, finance, and primatology. If something can be turned into a competition, it has probably been Elo-ed. Somehow, a simple chess algorithm has become an all-purpose tool for rating everything. In other words, when it comes to the preferred way to rate things, Elo ratings have the highest Elo rating. [...]

Elo ratings don't inherently have anything to do with chess. They're based on a simple mathematical formula that works just as well for any one-on-one, zero-sum competition -- which is to say, pretty much all sports. In 1997, a statistician named Bob Runyan adapted the formula to rank national soccer teams -- a project so successful that FIFA eventually adopted an Elo system for its official rankings. Not long after, the statistician Jeff Sagarin applied Elo to rank NFL teams outside their official league standings. Things really took off when the new ESPN-owned version of Nate Silver's 538 launched in 2014 and began making Elo ratings for many different sports. Some sports proved trickier than others. NBA basketball in particular exposed some of the system's shortcomings, Neil Paine, a stats-focused sportswriter who used to work at 538, told me. It consistently underrated heavyweight teams, for example, in large part because it struggled to account for the meaninglessness of much of the regular season and the fact that either team might not be trying all that hard to win a given game. The system assumed uniform motivation across every team and every game. Pretty much anything, it turns out, can be framed as a one-on-one, zero-sum game. Arpad Emmerich Elo, creator of the Elo rating system, understood the limitations of his invention. "It is a measuring tool, not a device of reward or punishment," he once remarked. "It is a means to compare performances, assess relative strength, not a carrot waved before a rabbit, or a piece of candy given to a child for good behavior."
