They create a dedicated desktop icon for your favorite web-based application — a simplified browser that opens to that single URL. Yet while Linux usually offers the same functionality as other operating systems, "Peppermint OS's Ice and its successor Kumo are the only free software versions of Site-Specific Browsers available on Linux," according to Linux magazine. "Fortunately for those who want this functionality, Peppermint OS is a Debian derivative, and both can be installed on Debian and most other derivatives." Since SSBs first appeared in 2005, they have been available on both Windows and macOS. On Linux, however, the availability has come and gone. On Linux, Firefox once had an SSB mode, but it was discontinued in 2020 on the grounds that it had multiple bugs that were time-consuming to fix and there was "little to no perceived user benefit to the feature." Similarly, Chromium once had a basic SSB menu item, Create Application Shortcut, which no longer appears in recent versions. As for GNOME Web's (Epiphany's) Install Site as Web Application, while it still appears in the menu, it is no longer functional. Today, Linux users who want to try SSBs have no choices except Ice or Kumo. Neither Ice or Kumo appears in any repository except Peppermint OS's. But because Peppermint OS installs packages from Debian 12 ("bookworm"), either can be installed to Debian or a derivative... To install successfully, at least one of Firefox, Chrome, Chromium, or Vivaldi also must be installed... Because both Ice and Kumo are written in Python, they can be run on any desktop. The article concludes that Site-Specific Browsers might make more sense "on a network or in a business where their isolation provides another layer of security. Or perhaps the time for SSBs is past and there's a reason browsers have tried to implement them, and then discarded them."

"[F]or years it was written off," writes CNN. " 'The economics were just way out,' said Martin Soltau, CEO of the UK-based company Space Solar. "That may now be changing as the cost of launching satellites falls sharply, solar and robotics technology advances swiftly, and the need for abundant clean energy to replace planet-heating fossil fuels becomes more urgent." There's a "nexus of different technologies coming together right now just when we need it," said Craig Underwood, emeritus professor of spacecraft engineering at the University of Surrey in the U.K. The problem is, these technologies would need to be deployed at a scale unlike anything ever done before... "The big stumbling block has been simply the sheer cost of putting a power station into orbit." Over the last decade, that has begun to change as companies such as SpaceX and Blue Origin started developing reusable rockets. Today's launch costs at around $1,500 per kilogram are about 30 times less than in the Space Shuttle era of the early 1980s. And while launching thousands of tons of material into space sounds like it would have a huge carbon footprint, space solar would likely have a footprint at least comparable to terrestrial solar per unit of energy, if not a smaller, because of its increased efficiency as sunlight is available nearly constantly, said Mamatha Maheshwarappa, payload systems lead at UK Space Agency. Some experts go further. Underwood said the carbon footprint of space-based solar would be around half that of a terrestrial solar farm producing the same power, even with the rocket launch... There is still a huge gulf between concept and commercialization. We know how to build a satellite, and we know how to build a solar array, Maheshwarappa said. "What we don't know is how to build something this big in space..." Scientists also need to figure out how to use AI and robotics to construct and maintain these structures in space. "The enabling technologies are still in a very low technology readiness," Maheshwarappa said. Then there's regulating this new energy system, to ensure the satellites are built sustainably, there's no debris risk, and they have an end-of-life plan, as well as to determine where rectenna sites should be located. Public buy-in could be another huge obstacle, Maheshwarappa said. There can be an instinctive fear when it comes to beaming power from space. But such fears are unfounded, according to some experts. The energy density at the center of the rectenna would be about a quarter of the midday sun. "It is no different than standing in front of a heat lamp," Hajimiri said. The article argues that governments and companies around the world "believe there is huge promise in space-based solar to help meet burgeoning demand for abundant, clean energy and tackle the climate crisis." And they cite several specific examples: In 2020 the U.S. Naval Research Lab launched a module on an orbital test vehicle, to test solar hardware in space conditions. This year Caltech electrical engineering professor led a team that successfully launched a 30-centimeter prototype equipped with transmitters — and successfully beamed detectable energy down to earth. In June the U.K. government announced over $5 million in funding to universities and tech companies "to drive forward innovation" in the space-based solar sector. The U.S. Air Force Research Lab plans to launch a small demonstrator in 2025. Europe's its Solaris program aims to prove "the technical and political viability of space-based solar, in preparation for a possible decision in 2025 to launch a full development program." One Chinese spacecraft designer and manufacturer hopes to send a solar satellite into low orbit in 2028 and high orbit by 2030, according to a 2022 South China Morning News report.

"Billions of people" uses social media every month, notes the Wall Street Journal.. But "fewer and fewer are actually posting." Instead they're favoring "a more passive experience, surveys of users and research from data-analytics firms say." In an October report from data-intelligence company Morning Consult, 61% of U.S. adult respondents with a social-media account said they have become more selective about what they post. The reasons are varied: People say they feel they can't control the content they see. They have become more protective about sharing their lives online. They also say the fun of social media has fizzled. This lurker mentality is widespread, across Meta Platforms' Instagram and Facebook along with X and TikTok.... In a survey conducted in the U.S. this summer, research firm Gartner found more than half of respondents believed the quality of social media has declined in the past five years. They cited misinformation, toxicity and the proliferation of bots as reasons it has gotten worse. "The less you trust social-media brands, the less of a good experience you're having," says Gartner analyst Emily Weiss. Users are less likely to share opinions or insight into their lives since the community they are looking for isn't there, she adds. Ads and suggested posts have also sucked the joy out of apps, some users say... The algorithmic spotlight on creators and their hyper-curated content has made some users feel insecure and less likely to share their own photos and videos, says Kevin Tran, media and entertainment analyst at Morning Consult. In turn, some now think of social apps more as sources of entertainment, like YouTube or Netflix. Gartner estimates that 50% of users will either abandon or significantly limit their interactions with social media in the next two years. Any threat to interacting is a threat to business, the article notes, adding "The companies are responding." They are investing in more private user experiences like messaging, and making interactions more secure. And encouraging people to post to a more intimate audience — as with Instagram's recently expanded Close Friends feature... Meta responded to user complaints, saying it would continue to work on improving recommendations to help creators reach more people. The company added a snooze button that pauses suggested posts for 30 days at a time, and chronological feeds that temporarily only show posts from accounts people follow... Meta began shifting its resources toward messaging, including efforts to enable end-to-end encryption by default across all of its messaging services... TikTok has also shown signs of investing more in the messaging portion of its app, nudging users to chat with people they haven't messaged in a while. When the Wall Street Journal posted their article on Threads, Adam Mosseri (head of Instagram) responded that "People are sharing to feeds less, but to Stories more," and "even more still" in Messages ("even photos and videos"). Mosseri also said that Instagram's Notes feature — basically a post where you cab specify a smaller subset of your followers to see it — "have quickly become a big thing, particularly for young people. "So it's no so much that people are sharing less," Mosseri argued, "but rather than they're sharing differently."

CNN describes them as "towering waves," driven into California's coastline by powerful storms and "posing a significant risk to people and structures along the coast." Monstrous, 20-foot-plus waves on Thursday crashed over seawalls and swept away and injured several people, forced rescues and sent a damaging surge of water through coastal California streets. Dangerous waves continued to slam the coast on Friday, forcing beaches to close. All Ventura County beaches will be closed through New Year's Eve because of the 15- to 20-foot waves expected along the central and Southern California coasts through Saturday evening... Sea levels have risen along most of the California coastline over the past century, NOAA data shows, as global temperatures climb and melt glaciers and ice sheets. Higher sea levels are making coastal flooding events worse and will continue to do so in the future. The first round of dangerous waves hit alongside high tide Thursday morning. Several people were injured by a huge wave that slammed into Pierpont in the Ventura Beach area... Nearly 20 people were briefly swept away in the incident and eight people were taken to the hospital, Ventura officials said. One bystander even filmed what CNN calls a"monster" wave, "the surge sweeping people and vehicles down the street... The massive waves pummeling the coastline, reeking havoc, flooding streets and businesses." CNN's report also includes footage from nearly 300 miles north, showing a wave flooding a beachfront restaurant's courtyard in Santa Cruz, California. ("I just feel bad for the restaurants," says one local. "I know they just went through renovations from the last time this happened.") CNN's original article notes the sheriff's office there briefly issued an evacuation warning for some areas for part of Thursday, including one "where seawater filled beachside roadways and pushed against some homes, CNN affiliate KION reported." And CNN's video report concludes by noting that "Parts of the California coast could see towering waves through the weekend, coastal flood and high surf alerts stretching from the southern border to the Bay Area."

NBC News reports that the Chinese spy balloon that flew across the U.S. in February "used an American internet service provider to communicate, according to two current and one former U.S. official familiar with the assessment." it used the American ISP connection "to send and receive communications from China, primarily related to its navigation." Officials familiar with the assessment said it found that the connection allowed the balloon to send burst transmissions, or high-bandwidth collections of data over short periods of time. The Biden administration sought a highly secretive court order from the federal Foreign Intelligence Surveillance Court to collect intelligence about it while it was over the U.S., according to multiple current and former U.S. officials. How the court ruled has not been disclosed. Such a court order would have allowed U.S. intelligence agencies to conduct electronic surveillance on the balloon as it flew over the U.S. and as it sent and received messages to and from China, the officials said, including communications sent via the American internet service provider... The previously unreported U.S. effort to monitor the balloon's communications could be one reason Biden administration officials have insisted that they got more intelligence out of the device than it got as it flew over the U.S. Senior administration officials have said the U.S. was able to protect sensitive sites on the ground because they closely tracked the balloon's projected flight path. The U.S. military moved or obscured sensitive equipment so the balloon could not collect images or video while it was overhead. NBC News is not naming the internet service provider, but says it denied that the Chinese balloon had used its network, "a determination it said was based on its own investigation and discussions it had with U.S. officials." The balloon contained "multiple antennas, including an array most likely able to collect and geolocate communications," according to reports from a U.S. State Depratment official cited by NBC News in February. "It was also powered by enormous solar panels that generated enough power to operate intelligence collection sensors, the official said. Reached for comment this week, a spokesperson for the Chinese Embassy in Washington told NBC News that the balloon was just a weather balloon that had accidentally drifted into American airspace.

An anonymous reader quotes a report from New Atlas: Researchers have developed a new, lightweight foam made from carbon nanotubes that, when used as a helmet liner, absorbed the kinetic energy caused by an impact almost 30 times better than liners currently used in US military helmets. The foam could prevent or significantly reduce the likelihood of concussion in military personnel and sportspeople. Among sportspeople and military vets, traumatic brain injury (TBI) is one of the major causes of permanent disability and death. Injury statistics show that the majority of TBIs, of which concussion is a subtype, are associated with oblique impacts, which subject the brain to a combination of linear and rotational kinetic energy forces and cause shearing of the delicate brain tissue. To improve their effectiveness, helmets worn by military personnel and sportspeople must employ a liner material that limits both. This is where researchers from the University of Wisconsin-Madison come in. Determined to prevent -- or lessen the effect of -- TBIs caused by knocks to the body and head, they've developed a new lightweight foam material for use as a helmet liner. For the current study, Thevamaran built upon his previous research into vertically aligned carbon nanotube (VACNT) foams -- carefully arranged layers of carbon cylinders one atom thick -- and their exceptional shock-absorbing capabilities. Current helmets attempt to reduce rotational motion by allowing a sliding motion between the wearer's head and the helmet during impact. However, the researchers say this movement doesn't dissipate energy in shear and can jam when severely compressed following a blow. Instead, their novel foam doesn't rely on sliding layers. VACNT foam sidesteps this shortcoming via its unique deformation mechanism. Under compression, the VACNTs undergo collective sequentially progressive buckling, from increased compliance at low shear strain levels to a stiffening response at high strain levels. The formed compression buckles unfold completely, enabling the VACNT foam to accommodate large shear strains before returning to a near initial state when the load is removed. The researchers found that at 25% precompression, the foam exhibited almost 30 times higher energy dissipation in shear -- up to 50% shear strain -- than polyurethane-based elastomeric foams of similar density. The study has been published in the journal Experimental Mechanics.

"Predating even Toy Story, ReBoot was the first 3D animated television show," writes longtime Slashdot reader sandbagger, sharing a new report from Global News. "The master tapes have been located in storage but the hardware needed to play the 1990s-era media has yet to be located." From the report: Produced in Vancouver by Mainframe Entertainment, it aired on YTV between 1994 and 2001, and decades later still has a committed fan base. Among those super fans are Jacob Weldon and Raquel Lin, a B.C. duo now crafting a documentary about the creation of the show and its impact in the film and TV world. Weldon said he wants to see ReBoot recognized for its place in the evolution of computer animation -- recognition he said it rarely gets. When ReBoot was finally cancelled -- cut short in its fourth and final season -- its protagonists were left in peril and the show ended on a cliffhanger. It's another factor that Lin and Weldon say has helped immortalize the show and has helped fans hoping for a revival that might finally explain the characters' fate. Earlier this month, the documentary also got a potential major boost. Mainframe allowed Lin and Weldon to come to the studio to look for the show's original master tapes, recordings some believed might have been permanently lost. They struck gold. "They had boxes upon boxes upon boxes, hundreds of tapes," Lin said. "It's original resolution, original frame rate, uncompressed. If we could get a deck to play these, they would look beautiful," Weldon said. Finding that deck, however, is the pair's next major challenge. The recordings are on a rare digital tape format called D1, a technology that Weldon said was cutting edge and rare when Mainframe was using it. It's even harder to find today, and even Mainframe doesn't have the equipment to play the tapes back. Weldon and Lin have since put out a call on social media for a working Bosch BTS D1 deck that would allow them to play the tapes, and incorporate them into their documentary. "I can't tell you how many people have called us, DM'd us, emailed us -- people from all over the world," Lin said. While the pair still haven't secured the deck, they're aiming to release their documentary by next summer. They're hoping it will help renew interest in the show, introduce it to new generations and perhaps see it get new life on a streaming platform.

SpaceX on Thursday launched two rockets into orbit, only three hours apart, bringing its total number of launches to 98 in 2023. Space.com reports: The first SpaceX mission to take to the skies Thursday (Dec. 28) was a Falcon Heavy rocket carrying the U.S. military's secretive X-37B space plane, designed mission USSF-52. That blasted off from NASA's Kennedy Space Center in Florida at 8:07 p.m. EST (0107 GMT on Dec. 29). This marked the second Falcon Heavy flight of 2023. Second up on the launch docket for Thursday, hours later, was a Falcon 9 liftoff carrying 23 SpaceX Starlink units to low Earth orbit from nearby Cape Canaveral Space Force Station. This launch took place at 11:01 p.m. EST (0401 GMT on Dec. 29). This was SpaceX's 98th and final launch of 2023, and the 96th flight for a Falcon 9 rocket this year. SpaceX's 97th launch overall for this year marked the seventh flight for X-37B, but the first time the space plane hitched a lift atop a Falcon Heavy rocket. The X-37B/Falcon Heavy launch had been scrubbed several times previously due to bad weather and an issue with ground equipment. The launch of 23 Starlink broadband satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida that capped off 2023 was also the 96th launch of a Falcon 9 rocket during this year. SpaceX's next launch is targeted for Jan. 2, 2024 and will see a further 21 Starlink satellites lift to orbit to join the over 5,500 internet supplying units currently orbiting Earth.

An anonymous reader quotes a report from the Financial Times: Pink-haired Aitana Lopez is followed by more than 200,000 people on social media. She posts selfies from concerts and her bedroom, while tagging brands such as haircare line Olaplex and lingerie giant Victoria's Secret. Brands have paid about $1,000 a post for her to promote their products on social media -- despite the fact that she is entirely fictional. Aitana is a "virtual influencer" created using artificial intelligence tools, one of the hundreds of digital avatars that have broken into the growing $21 billion content creator economy. Their emergence has led to worry from human influencers their income is being cannibalized and under threat from digital rivals. That concern is shared by people in more established professions that their livelihoods are under threat from generative AI -- technology that can spew out humanlike text, images and code in seconds. But those behind the hyper-realistic AI creations argue they are merely disrupting an overinflated market. "We were taken aback by the skyrocketing rates influencers charge nowadays. That got us thinking, 'What if we just create our own influencer?'" said Diana Nunez, co-founder of the Barcelona-based agency The Clueless, which created Aitana. "The rest is history. We unintentionally created a monster. A beautiful one, though." Over the past few years, there have been high-profile partnerships between luxury brands and virtual influencers, including Kim Kardashian's make-up line KKW Beauty with Noonoouri, and Louis Vuitton with Ayayi. Instagram analysis of an H&M advert featuring virtual influencer Kuki found that it reached 11 times more people and resulted in a 91 per cent decrease in cost per person remembering the advert, compared with a traditional ad. "It is not influencing purchase like a human influencer would, but it is driving awareness, favorability and recall for the brand," said Becky Owen, global chief marketing and innovation officer at Billion Dollar Boy, and former head of Meta's creator innovations team. "Influencers themselves have a lot of negative associations related to being fake or superficial, which makes people feel less concerned about the concept of that being replaced with AI or virtual influencers," said Rebecca McGrath, associate director for media and technology at Mintel. "For a brand, they have total control versus a real person who comes with potential controversy, their own demands, their own opinions," McGrath added.

In 2021, Philips pulled its popular sleep apnea machines and ventilators off the shelves after discovering that an industrial foam built into the devices to reduce noise could release toxic particles and fumes into the masks worn by patients. "But as Philips publicly pledged to send out replacements, supervisors inside the company's headquarters near Pittsburgh were quietly racing to manage a new crisis that threatened the massive recall and posed risks to patients all over again," reports ProPublica. "Tests by independent laboratories retained by Philips had found that a different foam used by the company -- material fitted inside the millions of replacement machines -- was also emitting dangerous chemicals, including formaldehyde, a known carcinogen." "Though Philips has said the machines are safe, ProPublica and the Pittsburgh Post-Gazette obtained test results and other internal records that reveal for the first time how scientists working for the company grew increasingly alarmed and how infighting broke out as the new threat reached the highest levels of the Pittsburgh operation. The findings also underscore an unchecked pattern of corporate secrecy that began long before Philips decided to use the new foam." From the report: The company had previously failed to disclose complaints about the original foam in its profitable breathing machines, a polyester-based polyurethane material that was found to degrade in heat and humidity. Former patients and others have described hundreds of deaths and thousands of cases of cancer in government reports. After the introduction of the new foam in 2021, this one made of silicone, the company again held back details about the problem from the public even as it sent out replacement machines with the new material to customers around the world. One of the devices was the DreamStation 2, a newly released continuous positive airway pressure, or CPAP, machine promoted as one of the company's primary replacements. Federal regulators were alerted to the concern more than two years ago but said in a news release at the time that the company was carrying out additional tests on the foam and that patients should keep using their replacements until more details were available. The Food and Drug Administration has not provided new information on the test results since then, and it is still unclear whether the material is safe. That leaves millions of people in the United States alone caught in the middle, including those with sleep apnea, which causes breathing to stop and start through the night and can lead to heart attacks, strokes and sudden death. The new foam isn't the only problem: An internal investigation at Philips launched in the months after the recall found that water was condensing in the circuitry of the DreamStation 2, creating a new series of safety risks. "Loss of therapy, thermal events, and shock hazards," the investigation concluded. The FDA issued an alert about overheating last month, warning that the devices could produce "fire, smoke, burns, and other signs of overheating" and advising patients to keep the machines away from carpet, fabric and "other flammable materials." Philips has said that customers could continue using the devices if they followed safety instructions. ...

Deliveries of the world's first mass-produced electric vehicle equipped with a sodium-ion battery will begin in January 2024. According to CarNewsChina, they're being produced by JAC Motors, a Volkswagen-backed Chinese automaker, through its new Yiwei EV brand. From the report: The Yiwei EV hatchback will have a cylindrical sodium-ion pack from Beijing-based HiNa Battery and adopt JAC's UE (Unitized Encapsulation) module technology. UE is also known as a honeycomb design because of its appearance. It is another battery structure concept like CATL's CTP (cell-to-pack) or BYD's Blade battery. Yiwei is a new EV brand under Anhui Jianghuai Automobile (JAC), established in 2023. JAC's parent company, Anhui Jianghuai Automobile Group Holdings (JAG), is 50% state-owned, and 50% belongs to Volkswagen Group. The German automotive giant acquired its stake in 2020 in an unprecedented move to invest in China's state-owned car maker. [...] In February 2023, JAC announced they were the first automaker to put the lithium-free sodium-ion battery on an electric vehicle. That EV was a Sehol E10X hatchback, and the Na+ battery had the following specifications: 25 kWh capacity, 120 Wh/kg energy density (single cell 140 Wh/kg), 3C to 4C charging (10% - 80% in 20 minutes), 252 km (157 miles) range for E10X, and HiNa NaCR32140 cell. Sehol was a brand under Volkswagen Anhui JV, which VW transferred to JAC in 2021. When the Yiwei brand was launched in May 2023, JAC announced that it would ditch the Sehol brand, and all vehicles are being rebadged to JAC or Yiwei. The pictures JAC released today tell us that the new sodium-ion-powered EV is the Sehol E10X. JAC hasn't yet confirmed the name of the new car under the Yiwei brand; it could be Yiwei E10X, but we have to wait for JAC's confirmation. JAC recently pushed a lot into sodium-ion batteries R&D. During the Shanghai Auto Show in April 2023, the company showcased its first car under the Yiwei brand called Yiwei 3, which was equipped with a sodium-ion battery. However, the EV launched later in June, only with a classic LFP lithium battery, and promised the Na+ variant would come later. The Yiwei 3 is a compact hatchback that competes with Wuling Bingo, BYD Seagull, or ORA Funky Cat. It has two power train options, both front-wheel drive: 70 kW and 100 kW motor. The maximum cruising range is 505 km CLTC with a 51.5 kWh battery.
