Windows blog: Today we are beginning to roll out an update for the Paint app to Windows Insiders in the Canary and Dev Channels (version 11.2308.18.0 or higher). With this update, we are introducing support for layers and transparency! You can now add, remove, and manage layers on the canvas to create richer and more complex digital art. With layers, you can stack shapes, text, and other image elements on top of each other. To get started, click on the new Layers button in the toolbar, which will open a panel on the side of the canvas. This is where you can add new layers to the canvas. Try changing the order of layers in this panel to see how the order of stacked image elements on the canvas changes. You can also show or hide and duplicate individual layers or merge layers together.

We are adding support for transparency as well, including the ability to open and save transparent PNGs! When working with a single layer, you will notice a checkerboard pattern on the canvas indicating the portions of the image that are transparent. Erasing any content from the canvas now truly erases the content instead of painting the area white. When working with multiple layers, if you erase content on one layer, you will reveal the content in layers underneath.

Apple on Monday rolled out iOS 17, iPadOS 17, tvOS 17, HomePod 17 and watchOS 10, the latest operating system versions for all its devices minus the Mac lineup. iOS 17: iOS 17 expands on last year's Lock Screen updates with the addition of interactive widgets and StandBy, a new feature that turns the iPhone into a mini home hub when it is charging. You can now see voicemail transcriptions in real time, and leave video messages in FaceTime. FaceTime also now works on the Apple TV with tvOS 17. With NameDrop, exchanging contacts is as simple as touching two phones together, and Messages has been overhauled with new safety features and updates to the way that stickers work. Autocorrect is better than ever, Spotlight search has been improved, private browsing in Safari is more secure with Face ID lock, and there's now a mood tracking feature in the Health app. Passwords can be shared in iCloud Keychain and AirTags can be shared among family members too, plus there are new features for the AirPods Pro. Apple has also added updates to Siri, Mail, Reminders, Notes, Home, and more. tvOS 17: In tvOS 17, Apple has added a FaceTime app for FaceTime calls on a larger screen. The feature works through an iPhone or iPad running iOS 17/iPadOS 17, with the iOS device serving as the camera and the TV serving as the display. With a Split View option, you can place your FaceTime call on one side of the TV and a TV show or game on the other side for SharePlay experiences. [...] Other new features include Dolby Vision 8.1 support, an enhance dialogue option to make it easier to hear what's being said over music and effects, and support for third-party VPN apps.

Panos Panay, the chief product officer at Microsoft leading Windows development and the company's Surface line, is leaving Microsoft. From a report: In an announcement on Monday, Microsoft told employees: "After nearly 20 years at the company, Panos Panay has decided to leave Microsoft." Panay first joined Microsoft in 2004 as a group program manager. After overseeing the company's Surface line, Panay became the company's chief product officer in 2018, where he led the development of Windows 11.

Saturday the San Francisco Chronicle published a joint opinion piece from MIT professor Carlo Ratti (who directs an MIT digital lab exploring the collection of digital data about urban life) and John Rossant (founder of the collaborative data-sharing platform CoMotion).

Together they penned a warning about a future filled with robotaxis. "Their convenience could seduce us into vastly overusing our cars. The result? An artificial-intelligence-powered nightmare of traffic, technically perfect but awful for our cities." Why do we believe this? Because it has already come to pass with ride-sharing. In the 2010s, the Senseable City Lab at the Massachusetts Institute of Technology, where one of us serves as the director, was at the forefront of using Big Data to study how ride-hailing and ride-sharing could make our streets cleaner and more efficient. The findings appeared to be astonishing: With minimal delays to passengers, we could match riders and reduce the size of New York City taxi fleets by 40%. More people could get around in fewer cars for less money. We could reduce car ownership, and free up curbs and parking lots for new uses. This utopian vision was not only compelling but within reach.

After publishing our results, we started the first collaboration between MIT and Uber to research a then-new product: Uber Pool (now rebranded UberX Share), a service that allows riders to share cars when heading to similar destinations for a lower cost. Alas, there is no such thing as a free lunch. Our research was technically right, but we had not taken into account changes in human behavior. Cars are more convenient and comfortable than walking, buses and subways — and that is why they are so popular. Make them even cheaper through ride-sharing and people are coaxed away from those other forms of transit. This dynamic became clear in the data a few years later: On average, ride-hailing trips generated far more traffic and 69% more carbon dioxide than the trips they displaced. We were proud of our contribution to ride-sharing but dismayed to see the results of a 2018 study that found that Uber Pool was so cheap it increased overall city travel: For every mile of personal driving it removed, it added 2.6 miles of people who otherwise would have taken another mode of transportation.

As robotaxis are on the cusp of proliferating across the world, we are about to repeat the same mistake, but at a far greater scale... [W]e cannot let a shiny new piece of technology drive us into an epic traffic jam of our own making. The best way to make urban mobility accessible, efficient and green is not about new technologies — neither self-driving cars nor electric ones — but old ones. Buses, subways, bikes and our own two feet are cleaner, cheaper and more efficient than anything Silicon Valley has dreamt up... Autonomous technology could, for example, allow cities to offer more buses, shuttles and other forms of public transit around the clock. That's because the availability of on-demand AVs could assure "last-mile" connections between homes and transit stops. It could also be a godsend for older people and those with disabilities. However, any scale-up of AVs should be counterbalanced with investments in mass transit and improvements in walkability.

Above all, we must put in place smart regulatory and tax regimes that allow all sustainable mobility modes — including autonomous services — to scale safely and intelligently. They should include, for example, congestion fees to discourage overuse of individual vehicles.

"Here is another radical replacement for the traditional combustion engine," writes long-time Slashdot reader Inzkeeper. "Check out the Astron Aerospace H2 Starfire Omega 1... an ICE engine with a turbine configuration."

The company "is claiming that it is a viable alternative to EVs," reports TopSpeed: Astron have showcased a 3D rendering of their engine which helps to understand this extremely complicated new powerplant in all of its glory. They also showed a functioning prototype which gives us a glimpse into how the engine could potentially function... The company claims that it weighs an absolutely mind-boggling 35 pounds yet produces horsepower in the region of 160 and about 170 pound-feet of torque. These are insane figures. The Omega 1 boasts an alleged 60 percent efficiency, which is absurd if true given that piston engines rarely ever top 40 percent efficiency. On top of this, Omega 1 can run on any kind of combustible fuel, meaning that hydrogen could easily be used to reduce emissions so close to zero that it's negligible.
HotCars adds that "According to Astron Aerospace, the engine idles at 1,000 rpm and redlines at an incredible 25,000 rpm — much higher than all the other rotaries we've seen. This is thanks to the circular movement, rather than the epitrochoidal movement used for Reuleaux triangle rotaries." The awesome thing about this engine is that it is stackable, meaning two of them will make 320 hp and 340 lb-ft, three will produce 480 hp and 510 lb-ft, etc... Astron Aerospace also stated that due to the design, the engine is easily scalable for other applications — for instance, marine engines. According to them and one of their renders, a larger version can easily reach 4,500 hp...

[I]t is not only more efficient than the equivalent piston engine — 80% compared to a mere 34% — but the engine is also much smaller and lighter. This translates to better fuel economy and a lighter overall vehicle. The engine is air-cooled as well, which means there aren't any additional radiators or other cooling systems needed to keep the engine working. Air-cooled may sound a bit old-fashioned, but in this case, it simplifies the whole package. The maintenance on such an engine would also be minimal, with Astron Aerospace claiming 60,000 miles further usage over a typical piston engine before maintenance is required.

The disadvantage of this engine is that it hasn't yet been thoroughly tested in real-world conditions. Astron Aerospace has patented the engine and has a working prototype but has found no investors to begin mass testing and production. The engine needs to be worked hard to flesh out any potential weak points and new materials need to be used to cope with the internal stresses and wear.

An anonymous reader shared this report from TechCrunch: In March, WordPress.com owner Automattic made a commitment to the fediverse — the decentralized social networks that include the Twitter rival Mastodon and others — with the acquisition of an ActivityPub plug-in that allows WordPress blogs to reach readers on other federated platforms. Now, the company is announcing ActivityPub 1.0.0 for WordPress has been released allowing WordPress blogs to be followed by others on apps like Mastodon and others in the fediverse and then receive replies back as comments on their own sites.

Since the acquisition, the company has improved on the original software in a number of ways, including by now allowing the ability to add blog-wide catchall accounts instead of only per-author. It also introduced the ability to add a "follow me" block to help visitors follow your profile and a "followers" block to show off your followers, noted Automattic design engineer Matt Wiebe, in a post on X... For the time being, the software supports self-hosted WordPress blogs, but Wiebe teased that support for WordPress.com blogs was "coming soon."
Last year Automattic's CEO Matt Mullenweg announced Tumblr would add support for ActivityPub, the article adds. "But more recently, Mullenweg told us he's been investigating not only ActivityPub, but also other protocols like Nostr and Bluesky's AT Protocol."

At 103 miles/kWh (or 0.6 kWh/100 km), the new "muc22" car built by students from the Technical University of Munich "is 25 times more efficient than any EV on sale..." writes Ars Technica. "For those who think in terms of miles per gallon, it's the equivalent of traveling 3,815 miles on a single gallon of gas.

The car has a top speed of just 26 mph (42 km/h) — and without a driver it weighs just 374 lbs (170 kg): In a six-day test at Munich airport, it set a new distance record on a single charge (for a non-solar EV): 1,599 miles (2,574 km), with less battery capacity than many plug-in hybrids — just 15.5 kWh...

The airflow-optimized shape has faired-in rear wheels and a drag coefficient of just 0.159; more importantly, though, it has a pretty tiny frontal area (it's only 39.4 inches/1,000 mm tall and 47.2 inches/1,200 mm wide)... [F]or this record run, muc22 made do with just 400 W — that's 268 times less powerful than the least-powerful EV on sale today, the Mazda MX-30... The record run took place in an empty hangar at Munich Airport, obviating any interference from the weather. The previous record stood at 999 miles (1,609 km), but the team of seven drivers reached that distance after just four days, and since the battery wasn't empty yet, the car kept going.
Thanks to Slashdot reader FrankOVD for sharing the article.

An anonymous reader quotes a report from Space.com: Firefly Aerospace just set a new responsive-launch record. The company's Alpha rocket lifted off from Vandenberg Space Force Base on Thursday (Sept. 14) at 10:28 p.m. EDT (7:28 p.m. local California time; 0228 GMT on Sept. 15), kicking off a mission for the U.S. Space Force called Victus Nox. The rocket roared off the pad just 27 hours after the U.S. Space Force gave the order -- less time than on any previous national security mission. The wheels for Victus Nox (Latin for "conquer the night") began turning in September 2022, when the Space Force awarded contracts to Texas-based Firefly and Millennium Space Systems, a Boeing subsidiary headquartered in the Los Angeles area that built the mission's payload.

On Aug. 30 of this year, Firefly and Millennium entered the mission's "hot standby" phase, a six-month period during which they could receive a launch-alert notice at any time. After receipt of that notice, Millennium and Firefly would have 60 hours to get the satellite from Millennium's Southern California facilities to Vandenberg, fuel it up and mate it to the Alpha rocket's payload adapter. The alert came through recently, and the mission teams hit their ambitious timeline. "Upon activation, the space vehicle was transported 165 miles [266 kilometers] from Millennium's El Segundo facility to Vandenberg Space Force Base where it was tested, fueled and mated to the launch adapter in just under 58 hours, significantly faster than the typical timeline of weeks or months," Space Force officials said in the emailed statement.

The teams then had to wait for the launch order, which would give them Victus Nox's orbital requirements. They would then have just 24 hours to update Alpha's trajectory and guidance software, encapsulate the satellite in its payload fairing, get the payload to the pad, mate it to Alpha and get the rocket ready to launch, Firefly wrote in a statement. The teams managed that task as well. They were ready to launch as soon as the first window opened, which was 27 hours after the Space Force gave the order. Victus Nox's speed goals didn't end with the successful liftoff. The teams now aim to get the satellite up and running within 48 hours of its deployment. The report notes that the previous response-launch record for a U.S. national security mission was 21 days, which was set in June 2021.

An anonymous reader quotes a report from New Atlas: Imperial College is developing a rocket thruster called the Iridium Catalysed Electrolysis CubeSat Thruster (ICE-Cube Thruster) that is so small that it can only be fabricated using techniques originally designed for making silicon chips. The entire thruster chip is about the length of a fingernail, with the combustion chamber and nozzle only measuring 1 mm long. It also requires only 20 watts of electric current to operate and in a test campaign generated 1.25 millinewtons of thrust at a specific impulse of 185 seconds on a sustained basis. To put that into perspective, that's half a billion times less thrust than the engines used on the Space Shuttle.

However, the party trick of the ICE-Cube Thruster is that it uses ordinary water as its propellant, which is about as non-explosive and non-flammable as you can get. Onboard electric current creates electrolysis to break down the water into hydrogen and oxygen, which is fed into the combustion chamber to ignite, generating thrust to maneuver the CubeSat. Using water is not only very green, it also reduces payload because no pressurization is needed to store it, so storage and handling systems can be lighter and simpler. However, fabricating the combustion chamber and nozzle for the thruster in what is essentially two dimensions required taking a page from microelectronics by using the Micro-Electrical Mechanical Systems (MEMS) technique normally employed for machining silicon wafers for processors to sub-micrometer tolerances.

Honda's new Motocompacto is a throwback all-electric ridable inspired by the short-lived scooter of the '80s. Engadget reports: The vehicle, folded up, resembles one of those Costco folding tables but with little aluminum wheels poking out the bottom. To transform it into a scooter, you extend the handlebars, seats and back wheel, and ride away on something vaguely approximating a bike. (To give you some perspective on the design, this thing is just over three feet long.)

Honda says its aluminum frame and wheels keep it "lightweight" but at 41 pounds it's firmly in the same weight class as regular e-bikes, and with a range of "up to 12 miles," it's not getting you very far either. After its 12-mile range is used up, it can be re-juiced in 3.5 hours, which is a considerable amount of time, but at least it comes with an on-board charger ready for you to plug into a 110V outlet. It'll be available starting in November priced "under $995" exclusively on Honda's website and at Honda and Acura dealers.

The cloud-based system the Air Force is co-developing with Canada to enable instantaneous combat data-sharing is just about ready for prime time, although the looming threat of a budget gap may slow its global deployment. The Drive reports: Cloud-based command-and-control (CBC2), a pillar of the service's Advanced Battle Management System (ABMS), will hit initial operating capability roughly on schedule next month, Brig. Gen. Luke Cropsey, integrating program officer for Command, Control, Communications and Battle Management, told The War Zone and other outlets this week at the Air, Space, and Cyber conference near Washington, D.C. It's headed to three unspecified base locations within the first half of 2024, Cropsey said, with others to follow at "more scale" as what's anticipated to be a five-year rollout plan gets underway. [...] CBC2 is designed to replace the hardware-based Battle Control System-Fixed, which provides command-and-control for Canada and the U.S., including Alaska and Hawaii. Officially made a program in 2022, CBC2 is "a set of microservice applications," according to an Air Force release, that can take in more than 750 radar feeds and deliver them to a single user interface. "The system then allows operators to create machine-generated courses of action to help shorten the tactical C2 kill chain and send a desired effect via machine-to-machine connections," the release adds.

In addition to delivering data faster and streamlining communication, CBC2 will build in new artificial intelligence elements. A January Government Accountability Office report states that it will build upon Pathfinder, an AI-empowered prototype that ingests "data that would in the past have been ... left on the cutting room floor," as North American Aerospace Defense Command chief Gen. Glen VanHerck put it in remarks reported by C4ISRNet. A September 2020 paper (PDF) from the Canada Institute described Pathfinder as "giving new life to old sensors" for NORAD's defense. "In a recent demonstration," the paper stated, "The Pathfinder system was tied to Federal Aviation Administration radars, and without any modification to the radars themselves, consistently demonstrated an ability to effectively detect and track very small unmanned aircraft, previously thought to be beyond the capability of the system."

According to The Information, Google is nearing the release of Gemini, its conversational artificial intelligence software intended to compete with OpenAI's GPT-4 model. Reuters reports: For Google, the stakes of Gemini's launch are high. Google has intensified investments in generative AI this year as it plays catch-up after Microsoft-backed OpenAI's launch of ChatGPT last year took the tech world by storm. Gemini is a collection of large-language models that power everything from chatbots to features that either summarize text or generate original text based on what users want to read like email drafts, music lyrics, or news stories, the report said. It is also expected to help software engineers write code and generate original images based on what users ask to see.

Google is currently giving developers access to a relatively large version of Gemini, but not the largest version it is developing which would be more on par with GPT-4, the report said. The search and advertising giant plans to make Gemini available to companies through its Google Cloud Vertex AI service.

An anonymous reader quotes a report from Reuters: Google agreed to pay $155 million to settle claims by California and private plaintiffs that the search engine company misled consumers about how it tracks their locations, and used their data without consent. Both settlements resolve claims that the Alphabet unit deceived people into believing they maintained control over how Google collected and used their personal data. The company was accused of being able to "profile" people and target them with advertising even if they turned off their "Location History" setting, and deceive people about their ability to block ads they did not want.

The California settlement requires Google to pay $93 million, and disclose more about how it tracks people's whereabouts and uses data it collects. Money from Google's $62 million settlement with private plaintiffs would, after deducting legal fees, go to court-approved nonprofit groups that track internet privacy concerns. Lawyers for the plaintiffs said this made sense because it was "infeasible" to distribute money to the approximately 247.7 million U.S. adults with mobile devices. "Google was telling its users one thing--that it would no longer track their location once they opted out--but doing the opposite and continuing to track its users' movements for its own commercial gain," California Attorney General Rob Bonta said in a statement. "That's unacceptable."

Apple has agreed to install updates for the iPhone 12 in France after French regulators ordered the company to stop selling the model because it emits electromagnetic radiation levels that exceed European Union standards. From a report: The company, which just unveiled its newest generation of iPhones, insists the 12 model is safe and the phones have been certified in countries around the world since its introduction in 2020. It says the problem raised by the French government agency that manages wireless communications frequencies is "related to a specific testing protocol."

The French agency said the iPhone 12 recently failed one of two types of tests for electromagnetic waves capable of being absorbed by the body. On Tuesday, France's government ordered a halt to sales of the iPhone 12 and told Apple to issue a software update to address the problem or face a recall. Apple said in a statement Friday that it "will issue a software update for users in France to accommodate the protocol used by French regulators." It did not elaborate.

A security company is calling out a feature in Google's authenticator app that it says made a recent internal network breach much worse. ArsTechnica: Retool, which helps customers secure their software development platforms, made the criticism on Wednesday in a post disclosing a compromise of its customer support system. The breach gave the attackers responsible access to the accounts of 27 customers, all in the cryptocurrency industry. The attack started when a Retool employee clicked a link in a text message purporting to come from a member of the company's IT team. It warned that the employee would be unable to participate in the company's open enrollment for health care coverage until an account issue was fixed. The text arrived while Retool was in the process of moving its login platform to security company Okta.

Most of the targeted Retool employees took no action, but one logged in to the linked site and, based on the wording of the poorly written disclosure, presumably provided both a password and a temporary one-time password, or TOTP, from Google authenticator. Shortly afterward, the employee received a phone call from someone who claimed to be an IT team member and had familiarity with the "floor plan of the office, coworkers, and internal processes of our company." During the call, the employee provided an "additional multi-factor code." It was at this point, the disclosure contended, that a sync feature Google added to its authenticator in April magnified the severity of the breach because it allowed the attackers to compromise not just the employee's account but a host of other company accounts as well.

TikTok has been fined 345 million euros ($370 million) for breaching privacy laws regarding the processing of children's personal data in the European Union, its lead regulator in the bloc said on Friday. From a report: The Chinese-owned short-video platform, which has grown rapidly among teenagers around the world in recent years, breached a number of EU privacy laws between July 31, 2020, and Dec. 31, 2020, Ireland's Data Protection Commissioner (DPC) said in a statement. It is the first time ByteDance-owned TikTok has been reprimanded by the DPC, the lead regulator in the EU for many of the world's top tech firms due to the location of their regional headquarters in Ireland.

A spokesperson for TikTok said it disagreed with the decision, particularly the size of the fine, and that most of the criticisms are no longer relevant as a result of measures it introduced before the DPC's probe began in September 2021. The DPC said TikTok's breaches included how in 2020 accounts for users under the age of 16 were set to "public" by default and that TikTok did not verify whether a user was actually a child user's parent or guardian when linked through the "family pairing" feature.

If you crack the screen on the Pixel Watch, getting it officially repaired by Google isn't on the cards. From a report: Several Pixel Watch owners have vented their frustrations about the inability to replace cracked screens, both on Reddit and in Google support forums. The Verge has also reviewed an official Google support chat from a reader who broke their Pixel Watch display after dropping the wearable. In it, a support representative states that Google "doesn't have any repair centers or service centers" for the device. "At this moment, we don't have any repair option for the Google Pixel Watch. If your watch is damaged, you can contact the Google Pixel Watch Customer Support Team to check your replacement options," Google spokesperson Bridget Starkey confirmed to The Verge.

An anonymous reader shares a report: Former NBA player Brandon Hunter passed away unexpectedly at the young age of 42 this week, a tragedy that rattled fans of his 2000s career with the Boston Celtics and Orlando Magic. But in an unhinged twist on what was otherwise a somber news story, Microsoft's MSN news portal published a garbled, seemingly AI-generated article that derided Hunter as "useless" in its headline. "Brandon Hunter useless at 42," read the article, which was quickly called out on social media. The rest of the brief report is even more incomprehensible, informing readers that Hunter "handed away" after achieving "vital success as a ahead [sic] for the Bobcats" and "performed in 67 video games." Condemnation for the disrespectful article was swift and forceful. "AI should not be writing obituaries," posted one reader. "Pay your damn writers â¦MSN." "The most dystopian part of this is that AI which replaces us will be as obtuse and stupid as this translation," wrote a redditor, "but for the money men, it's enough."

An anonymous reader quotes a report from UploadVR: Meta Avatars in Horizon Worlds now have virtual legs. If you launch Horizon Worlds and look in the mirror in the menu space, you'll see your avatar's full body, and you'll see it for other people too when you enter a world. The company's virtual avatars had previously faced widespread ridicule for their upper-body-only appearance. If you look down however you still won't see your own legs. This legs update only applies to third person avatars -- other people and yourself in the mirror -- not in first person.

Many VR apps & games already give you virtual legs in both first and third person. But no shipping VR system has built-in leg tracking, so virtual legs don't match the actual movement of your real legs. Further, there's not really a graceful way to handle the transition between sitting and standing, nor to make the legs look natural when moving around with the thumbstick. Some people don't mind these issues with fake virtual legs, but it feels disconcerting to others.

Legs had already arrived in the Quest home space (branded Horizon Home) two weeks ago for Quest firmware Public Test Channel users, but this is the first time they've arrived in a VR app. Third party apps using Meta Avatars (such as GOLF+) can't yet add legs though, as the SDK hasn't been updated. Horizon's developers seem to have early access to a new version.

Google and iFixit are expanding their partnership by offering several original parts for the Pixel tablet that Google had released in June. Google first partnered with iFixit in early 2022 to sell official replacement parts for its Pixel phones. Engadget reports: One of the most expensive components now available for sale is the tablet's rear case, which costs $200 and comes with three microphones, antennas, a power button with fingerprint unlock and volume controls. If your tablet's battery gets busted, you can now purchase an authentic replacement for $67, while a rear facing camera to replace one that's having issues will set you back $25. One replacement speaker will also cost you $25, as will a replacement for the device's USB-C port. But if it's the tablet's screen that needs replacing, you'll have to pay $200 or more. You can either get the part only -- consisting of a front glass digitizer screen, a 10.95-inch 2560 x 1600 pixel LCD and an 8-megapixel front-facing camera -- for that price or get a pack with tools you'll need to open up the tablet for $6 more.

iFixit, of course, doesn't just sell the parts: Its Pixel tablet portal also contains guides on how you can repair the model for each component it's selling. You can follow them if you want to be sure you're doing the right thing, even if you're pretty good at tinkering with electronics.
