[1] Phys.org republishes this article [2]from The Conversation :

> On average, managers [3]spend 23 hours a week in meetings . Much of what happens in them is considered to be of low value, or even entirely counterproductive. The [4]paradox is that bad meetings generate even more meetings... in an attempt to repair the damage caused by previous ones...

>

> A 2015 [5]handbook laid the groundwork for the nascent field of "Meeting Science". Among other things, the [6]research revealed that the real issue may not be the number of meetings, but rather how they are designed, the lack of clarity about their purpose, and the inequalities they (often unconsciously) reinforce... Faced with what we call meeting madness , the solution is not to eliminate meetings altogether, but to design them better. It begins with a simple but often forgotten question: why are we meeting...?

>

> The goal should not be to have fewer meetings, but better ones. Meetings that respect everyone's time and energy. Meetings that give a voice to all. Meetings that build connection.

Friday six European Union countries "asked the European Commission to water down an effective ban on the sale of internal combustion engine cars slated for 2035," [1]reports Reuters

> The countries have asked the EU Commission to allow the sale of hybrid cars or vehicles powered by other, existing or future, technologies "that could contribute to the goal of reducing emissions" beyond 2035, a joint letter seen by Reuters showed on Friday. The letter was signed by the prime ministers of Bulgaria, the Czech Republic, Hungary, Italy, Poland and Slovakia. They also asked for low-carbon and renewable fuels to be included in the plan to reduce the carbon emissions from transportation...

>

> Since they adopted a regulation that all new vehicles from 2035 should have zero emissions in March 2023, EU countries are [2]now having second thoughts . Back then, the outlook for battery electric vehicles was positive, but carmakers' efforts have later collided with the reality of lower-than-expected demand and fierce competition from China.

Car and Drive reports that Chancellor Friedrich Merz of Germany also " [3]wants to allow exceptions for plug-in hybrids, extended-range EVs, and 'highly efficient' combustion vehicles beyond the current 2035 deadline." They cite a [4]report in Automotive News .

> The European Commission hasn't made any official changes yet, but mounting pressure suggests that a revised plan could be coming soon.... Apostolos Tzitzikostas, the European Commissioner for Sustainable Transport and Tourism, was cited by the German paper [5]Handelsblatt as saying that the EU "will take all technological advances into account when reassessing fleet emission limits, including combustion engines running on e-fuels and biofuels." And these renewable products will apparently be key pieces of the puzzle. BMW uses a vegetable-oil-derived fuel called HVO 100 in its diesel products throughout Europe. The plant-oil-based fuel reportedly reduces tailpipe emissions by 90 percent compared with traditional diesel. For its part, Porsche has been working on producing synthetic fuel at a plant in Chile since 2022.

>

> The European Commission is set to meet on December 10. At that time, the body is expected to assemble a package of proposals to help out the struggling European automotive industry, though the actual announcement may be pushed to a later date.

AI is the second-largest major at M.I.T. after computer science, [1]reports the New York Times . ( [2]Alternate URL here and [3]here .) Though that includes students interested in applying AI in biology and health care — it's just the beginning:

> This semester, more than 3,000 students enrolled in a new [4]college of artificial intelligence and cybersecurity at the University of South Florida in Tampa. At the University of California, San Diego, 150 first-year students signed up for a [5]new A.I. major . And the State University of New York at Buffalo created a stand-alone "department of A.I. and society," which is offering new interdisciplinary degrees in fields like " [6]A.I. and policy analysis ...."

>

> [I]nterest in understanding, using and learning how to build A.I. technologies is soaring, and schools are racing to meet rising student and industry demand. Over the last two years, dozens of U.S. universities and colleges have announced new A.I. departments, majors, minors, courses, interdisciplinary concentrations and other programs.

"This is so cool to me to have the opportunity to be at the forefront of this," one 18-year-old told the New York Times . Their article points out 62% of America's computing programs reported drops in undergraduate enrollment this fall, according to [7]a report in October from the Computing Research Association.

"One reason for the dip: student employment concerns."

America's Energy Department runs a research lab in Idaho — and this week [1]announced successful results from a ground-breaking experiment . "This is the first time in history that chloride-based molten salt fuel has been produced for a fast reactor," says Bill Phillips, the lab's technical lead for salt synthesis. He calls it "a major milestone for American innovation and a clear signal of our national commitment to advanced nuclear energy."

> Unlike traditional reactors that use solid fuel rods and water as a coolant, most molten salt reactors rely on liquid fuel — a mixture of salts containing fissile material. This design allows for higher operating temperatures, better fuel efficiency, and enhanced safety. It also opens the door to new applications, including compact nuclear systems for ships and remote installations.

>

> "The Molten Chloride Fast Reactor represents a paradigm shift in the nuclear fuel cycle, and the Molten Chloride Reactor Experiment (MCRE) will directly inform the commercialization of that reactor," said Jeff Latkowski, senior vice president of TerraPower and program director for the Molten Chloride Fast Reactor. "Working with world-leading organizations such as INL to successfully synthesize this unique new fuel demonstrates how real progress in Gen IV nuclear is being made together."

>

> "The implications for the maritime industry are significant," said Don Wood, senior technical advisor for MCRE. "Molten salt reactors could provide ships with highly efficient, low-maintenance nuclear power, reducing emissions and enabling long-range, uninterrupted travel. The technology could spark the rise of a new nuclear sector — one that is mobile, scalable and globally transformative.

More details [2]from America's Energy Department :

> MCRE will require a total of 72 to 75 batches of fuel salt to go critical, making it the largest fuel production effort at INL since the operations of Experimental Breeder Reactor-II more than 30 years ago. The full-scale demonstration of the new fuel salt synthesis line for MCRE was made possible by a breakthrough in 2024. After years of testing, the team [3]found the right recipe to convert 95 percent of uranium metal feedstock into 18 kilograms of uranium chloride fuel salt in only a few hours — a process that previously took more than a week to complete...

>

> After delivering the first batch of fuel salt this fall, the team anticipates delivering four additional batches by March of 2026. MCRE is anticipated to run in 2028 for approximately six months at INL in the Laboratory for Operation and Testing (LOTUS) in the United States test bed.

"With the first batch of fuel salt successfully created at INL, researchers will now conduct testing to better understand the physics of the process, with a goal of moving the process to a commercial scale over the next decade," [4]says Cowboy State Daily .

A hardware security [1]response from ChatGPT ended with "Shop for home and groceries. Connect Target."

But "There are no live tests for ads" on ChatGPT, insists Nick Turley, OpenAI's head of ChatGPT. Posting on X.com, he said "any screenshots you've seen are either not real or not ads." [2] Engadget reports

> The OpenAI exec's explanation comes after [3]another post from former xAI employee Benjamin De Kraker on X that has gained traction, which featured a screenshot showing an option to shop at Target within a ChatGPT conversation. OpenAI's Daniel McAuley [4]responded to the post, arguing that it's not an ad but rather an example of app integration that the company announced in October. [To which De Kraker responded "when brands inject themselves into an unrelated chat and encourage the user to go shopping at their store, that's an ad. The more you pretend this isn't an ad because you guys gave it a different name, the less users like or trust you."]

>

> However, the company's chief research officer, Mark Chen, also replied on X that they "fell short" in this case, adding that "anything that feels like an ad needs to be handled with care."

>

> "We've turned off this kind of suggestion while we improve the model's precision," Chen wrote on X. "We're also looking at better controls so you can dial this down or off if you don't find it helpful."

It runs locally, a free/open source home automation platform connecting all your devices together, regardless of brand. And GitHub's senior developer calls it " [1]one of the most active, culturally important, and technically demanding open source ecosystems on the planet," with tens of thousands of contributors and millions of installations.

That's confirmed by this year's " [2]Octoverse" developer survey ...

> Home Assistant was one of the fastest-growing open source projects by contributors , ranking alongside AI infrastructure giants like vLLM, Ollama, and Transformers. It also appeared in the top projects attracting first-time contributors, sitting beside massive developer platforms such as VS Code... Home Assistant is now running in more than 2 million households , orchestrating everything from thermostats and door locks to motion sensors and lighting. All on users' own hardware, not the cloud. The contributor base behind that growth is just as remarkable: 21,000 contributors in a single year...

>

> At its core, Home Assistant's problem is combinatorial explosion. The platform supports "hundreds, thousands of devices... over 3,000 brands," as [maintainer Franck Nijhof] notes. Each one behaves differently, and the only way to normalize them is to build a general-purpose abstraction layer that can survive vendor churn, bad APIs, and inconsistent firmware. Instead of treating devices as isolated objects behind cloud accounts, everything is represented locally as entities with states and events. A garage door is not just a vendor-specific API; it's a structured device that exposes capabilities to the automation engine. A thermostat is not a cloud endpoint; it's a sensor/actuator pair with metadata that can be reasoned about.

>

> That consistency is why people can build wildly advanced automations. Frenck describes one particularly inventive example: "Some people install weight sensors into their couches so they actually know if you're sitting down or standing up again. You're watching a movie, you stand up, and it will pause and then turn on the lights a bit brighter so you can actually see when you get your drink. You get back, sit down, the lights dim, and the movie continues." A system that can orchestrate these interactions is fundamentally a distributed event-driven runtime for physical spaces. Home Assistant may look like a dashboard, but under the hood it behaves more like a real-time OS for the home...

>

> The local-first architecture means Home Assistant can run on hardware as small as a Raspberry Pi but must handle workloads that commercial systems offload to the cloud: device discovery, event dispatch, state persistence, automation scheduling, voice pipeline inference (if local), real-time sensor reading, integration updates, and security constraints. This architecture forces optimizations few consumer systems attempt.

"If any of this were offloaded to a vendor cloud, the system would be easier to build," the article points out. "But Home Assistant's philosophy reverses the paradigm: the home is the data center..."

As Nijhof says of other vendor solutions, "It's crazy that we need the internet nowadays to change your thermostat."

"People in their teens and early 20s are increasingly turning to old school tech," [1]reports the BBC , "in a bid to unplug from the online world."

> Amazon UK told BBC Scotland News that retro-themed products surged in popularity during its Black Friday event, with portable vinyl turntables, Tamagotchis and disposable cameras among their best sellers. Retailers Currys and John Lewis also said they had seen retro gadgets making a comeback with sales of radios, instant cameras and alarm clocks showing big jumps.

>

> While some people scroll endlessly through Netflix in search of their next watch, 17-year-old Declan prefers the more traditional approach of having a DVD in his hands. He grew up surrounded by his gran's collection and later bought his own after visiting a shop with a friend. "The main selling point for me is the cases," he says. Streaming services like Netflix and Disney+ dominate the market but Declan says he values ownership. "It's nice to have something you own instead of paying for subscriptions all the time," he says. "If I lost access to streaming tomorrow, I'd still have my favourite movies ready to watch."

>

> He admits DVDs are a "dying way of watching movies" but that makes them cheaper. "I think they're just cool, there's something authentic about having DVDs," he says. "These things are generations old, it's nice to have them available."

The BBC also writes that one 21-year-old likes the "deliberate artistry" of traditional-camera photography — and the nostalgic experience of using one. They interview a 20-year-old who says vinyl records have a "more authentic sound" — and he appreciates having the physical disc and jacket art.

And one 21-year-old even tracked down the handheld PlayStation Portable he'd used as a kid...

"Homebrew, the package manager for macOS and Linux, just got a handy new feature in the latest v5.0.4 update," [1]reports How-To Geek .

Brewfile install scripts "are now more like a one-stop shop for installing software, as Flatpaks are now supported alongside Brew packages, Mac App Store Apps, and other packages."

> For those times when you need to install many software packages at once, like when setting up a new PC or virtual machine, you can [2]create a Brewfile with a list of packages and run it with the ' brew bundle ' command. However, the Brewfile isn't limited to just Homebrew packages. You can also use it to install Mac App Store apps, graphical apps through [3]Casks , Visual Studio Code extensions, and Go language packages. Starting with this week's Homebrew v5.0.4 release, Flatpaks are now supported in Brewfiles as well...

>

> This turns Homebrew into a fantastic setup tool for macOS, Linux, and Windows Subsystem for Linux (WSL) environments. You can have one script with all your preferred software, and [4]use 'if' statements with platform variables and existing file checks for added portability.

FreeBSD 15.0-RELEASE [1]arrived this week , notes [2]this report from The Register , which calls it the latest release "of the Unix world's leading alternative to Linux."

> As well as numerous bug fixes and upgrades to many of its components, the major changes in this version are reductions in the number of platforms the OS supports, and in how it's built and how its component software is packaged.

>

> FreeBSD 15 has significantly reduced support for 32-bit platforms. Compared to [3]FreeBSD 14 in 2023 , there are no longer builds for x86-32, POWER, or ARM-v6. As the [4]release notes put it:

>

> "The venerable 32-bit hardware platforms i386, armv6, and 32-bit powerpc have been retired. 32-bit application support lives on via the 32-bit compatibility mode in their respective 64-bit platforms. The armv7 platform remains as the last supported 32-bit platform. We thank them for their service."

>

> Now FreeBSD supports five CPU architectures — two Tier-1 platforms, x86-64 and AArch64, and three Tier-2 platforms, armv7 and up, powerpc64le , and riscv64 .

>

> Arguably, it's time. AMD's first 64-bit chips [5]started shipping 22 years ago . Intel launched the [6]original x86 chip, the 8086 in 1978. These days, 64-bit is nearly as old as the entire Intel 80x86 platform was when the 64-bit versions first appeared. In comparison, a few months ago, [7]Debian 13 also dropped its x86-32 edition — six years after Canonical launched its first x86-64-only distro, [8]Ubuntu 19.10 .

>

> Another significant change is that this is the first version built under the new [9]pkgbase system, although it's still experimental and optional for now. If you opt for a pkgbase installation, then the core OS itself is installed from multiple separate software packages, meaning that the whole system can be updated using the package manager. Over in the Linux world, this is the norm, but Linux is a very different beast... The plan is that by FreeBSD 16, [10]scheduled for December 2027 , the restructure will be complete, the old distribution sets will be removed, and the current [11]freebsd-update command and its associated infrastructure can be turned off.

>

> Another significant change is [12]reproducible builds , a milestone the project [13]reached in late October . This change is part of a [14]multi-project initiative toward ensuring deterministic compilation: to be able to demonstrate that a certain set of source files and compilation directives is guaranteed to produce identical binaries, as a countermeasure against compromised code. A handy side-effect is that building the whole OS, including installation media images, no longer needs root access.

>

> There are of course other new features. Lots of drivers and subsystems have been updated, and this release has better power management, including suspend and resume. There's improved wireless networking, with support for more Wi-Fi chipsets and faster wireless standards, plus updated graphics drivers... The release announcement calls out the inclusion of [15]OpenZFS 2.4.0-rc4 , [16]OpenSSL 3.5.4 , and [17]OpenSSH 10.0 p2 , and notes the inclusion of some new quantum-resistant encryption systems...

>

> In general, we found FreeBSD 15 easier and less complicated to work with than either of the previous major releases. It should be easier on servers too. The new OCI container support in FreeBSD 14.2, which we [18]wrote about a year ago , is more mature now. FreeBSD has its own version of [19]Podman , and you can [20]run Linux containers on FreeBSD. This means you can use [21]Docker commands and tools , which are familiar to many more developers than FreeBSD's native Jail system.

"FreeBSD has its own place in servers and the public cloud, but it's getting easier to run it as a desktop OS as well," the article concludes. "It can run all the main Linux desktops, including GNOME on Wayland."

"There's no systemd here, and never will be — and no Flatpak or Snap either, for that matter.

Jolla is "trying again with a new crowd-funded smartphone," [1]reports Phoronix :

> Finnish company Jolla started out 14 years ago [2]where Nokia left off with MeeGo and developed Sailfish OS as a new Linux smartphone platform. Jolla [3]released their first smartphone in 2013 after crowdfunding but ultimately the Sailfish OS focus the past number of years now has been offering their software stack for use on other smartphone devices [including some Sony Xperia smartphones and OnePlus/Samsung/ Google/ Xiaomi devices].

This new Jolla Phone's [4]pre-order voucher page says the phone will only produced if 2,000 units are ordered before January 4. (But in just a few days they've already received 1,721 pre-orders — all discounted to 499€ from a normal price between 599 and 699 €). Estimate delivery is the first half of 2026. "The new Jolla Phone is powered by a high-performing Mediatek 5G SoC," [5]reports 9to5Linux , "and features 12GB RAM, 256GB storage that can be expanded to up to 2TB with a microSDXC card, a 6.36-inch FullHD AMOLED display with ~390ppi, 20:9 aspect ratio, and Gorilla Glass, and a user-replaceable 5,500mAh battery."

> The Linux phone also features 4G/5G support with dual nano-SIM and a global roaming modem configuration, Wi-Fi 6 wireless, Bluetooth 5.4, NFC, 50MP Wide and 13MP Ultrawide main cameras, front front-facing wide-lens selfie camera, fingerprint reader on the power key, a user-changeable back cover, and an RGB indication LED. On top of that, the new Jolla Phone promises a user-configurable physical Privacy Switch that lets you turn off the microphone, Bluetooth, Android apps, or whatever you wish.

>

> The device will be available in three colors, including Snow White, Kaamos Black, and The Orange. All the specs of the new Jolla Phone were voted on by Sailfish OS community members over the past few months. Honouring the original Jolla Phone form factor and design, the new model ships with Sailfish OS (with support for Android apps), a Linux-based European alternative to dominating mobile operating systems that promises a minimum of 5 years of support, no tracking, no calling home, and no hidden analytics...

>

> The device will be manufactured and sold in Europe, but Jolla says that it will design the cellular band configuration to enable global travelling as much as possible, including e.g. roaming in the U.S. carrier networks. The initial sales markets are the EU, the UK, Switzerland, and Norway.

Wired published an article by California-based writer/programmer Sheon Han arguing that Ruby " [1]is not a serious programming language ."

Han believes that the world of programming has "moved on", and "everything Ruby does, another language now does better, leaving it without a distinct niche.

> Ruby is easy on the eyes. Its syntax is simple, free of semicolons or brackets. More so even thanPython — a language known for its readability — Ruby reads almost like plain English... Ruby, you might've guessed, is dynamically typed. Python and JavaScript are too, but over the years, those communities have developed sophisticated tools to make them behave more responsibly. None of Ruby's current solutions are on par with those. It's far too conducive to what programmers call "footguns," features that make it all too easy to shoot yourself in the foot.

>

> Critically, Ruby's performance profile consistently ranks near the bottom (read: slowest) among major languages. You may remember Twitter's infamous "fail whale," the error screen with a whale lifted by birds that appeared whenever the service went down. You could say that Ruby was largely to blame. Twitter's collapse during the 2010 World Cup served as a wake-up call, and the company resolved to migrate its backend to Scala, a more robust language.

>

> The move paid off: By the 2014 World Cup, Twitter handled a record 32 million tweets during the final match without an outage. Its new Scala-based backend could process up to 100 times faster than Ruby. In the 2010s, a wave of companies replaced much of their Ruby infrastructure, and when legacy Ruby code remained, new services were written in higher-performance languages.

>

> You may wonderwhy people are still using Ruby in 2025. It survives because of its parasitic relationship with Ruby on Rails, the web framework that enabled Ruby's widespread adoption and continues to anchor its relevance.... Rails was the framework of choice for a new generation of startups. The main code bases of Airbnb, GitHub, Twitter, Shopify, and Stripe were built on it.

He points out on Stack Overflow's annual developer survey, Ruby has slipped from a top-10 technology in 2013 to #18 this year — "behind evenAssembly" — calling Ruby "a kind of professional comfort object, sustained by the inertia of legacy code bases and the loyalty of those who first imprinted upon it." But the article [2]drew some criticism on X.com . ("You should do your next piece about how Vim isn't a serious editor and continue building your career around nerd sniping developers.")

Other reactions...

"Maybe WIRED is just not a serious medium..."

Washington Post columnist Dana Milbank calls himself "a highly creative hypochondriac" — who just [1]paid for an expensive MRI scan to locate abnormal spots as tiny as 2 millimeters.

He discusses the pros and cons of its "diffusion-weighted imaging" technology combined with the pattern recognition of AI, which theoretically "has the potential to save our lives by revealing budding cancers, silent aneurysms and other hidden would-be killers before they become deadly. "

> But the scans cost $2,500 a pop and insurance won't pay. Worse, for every cancer these MRIs find, they produce a slightly greater number of false positives that require a biopsy, with the potential for infection and bleeding and emotional distress. Even when the scans don't produce a false positive, they almost always come up with some vague and disconcerting abnormality.... Will we feel better after viewing our insides? Or will we become anxious about things we hadn't even thought to worry about?

>

> Part of living has always been in the mystery, in not knowing what tomorrow will bring. Now, because of sophisticated imaging, genome sequencing and other revolutionary screening tools, we can have predictability, or at least the illusion of it. But do we want that? The American College of Radiology says we do not. Its [2]still-current 2023 statement says there is not "sufficient evidence" to recommend full-body screening, cautioning that the scan could lead to needless testing and expense. But David Larson, chair of ACR's Commission on Quality and Safety, told me that could change as more data comes in. "When people ask me, 'Would you recommend it?' I would say it depends on your tolerance for ambiguity," he said, giving the example of somebody found to have a borderline aortic aneurysm who is advised to wait and monitor it. If "that won't keep you up at night, then I wouldn't necessarily recommend against it...."

>

> About 1 in 20 gets that dreaded call. A [3]study Prenuvo presented earlier this year of 1,011 participants found that 4.9 percent of scans required a follow-up biopsy. Of those, 2.2 percent were actually cancer, and the other 2.7 percent were false positives. Of the 22 cancers the scans caught, 86 percent of patients had no specific symptoms. But if finding something truly awful is rare, finding something abnormal is almost guaranteed. [Vikash Modi, Prenuvo's senior medical director of preventative medicine] said only 1 in 20 scans come back completely clean. The vast majority of patients wind up in the ambiguous realm where something may look suspicious but doesn't require urgent follow-up.

He opted for the cheaper $1,000 torso scan, which the senior medical director calls "our bread-and-butter area," since 17 of the 22 cancers detected in one Prenuvo study were in that area and is where they often find cancers that wouldn't be discovered until they were incurable like "that scary pancreatic stuff...."

Milbank's scan found 12 "abnormalities" included "a 2.5 mm pulmonary nodule in the right lower lobe" and "a 4.6 mm intraductal papillary mucinous neoplasm in the pancreatic tail" — but with 10 abnormalities labeled "minor" (and six being musculoskeletal wear-and-tear problems "I already knew about from the usual aches and pains".)

> Even the two "moderate" findings didn't sound that grim when I read on. The "indeterminant lesion" in my lung requires no follow-up, while the thing in my pancreas is "low-risk."... The "most interesting" finding was the pancreatic cyst, because, at this size and location, there's a 3 percent chance it will become cancerous in the next five years. But if annual follow-up scans of my pancreas (covered by insurance) show it's getting bigger, the cyst can be removed before it becomes cancer. For me, this made the MRI worthwhile. Sure, there was a 97 percent likelihood the cyst never would develop into a problem even if I hadn't learned about it. But now, with minimal inconvenience, I can eliminate that 3 percent risk of getting pancreatic cancer, the [4]most lethal of major malignancies .

[1]Bloomberg reports that Google "must renegotiate any contract to make its search engine or artificial intelligence app the default for smartphones and other devices every year, a federal judge ruled."

> Judge Amit Mehta in Washington sided with the US Justice Department on the one year limitation in his final ruling on what changes the search giant must make in the wake of a landmark ruling that the company illegally monopolized online search. The yearly renegotiation will give rivals — particularly those in the burgeoning generative AI field — a chance to compete for key placements.

>

> The final judgment will still allow Google to offer its products to Apple Inc. for use in its popular iPhone and pay other electronics makers like Samsung Electronics Co. for default placement. But the judge said those contracts must be renegotiated annually. Mehta noted in his ruling that both Google and the US government said they could work with the one-year limitation on default contracts. As such, "the court holds that a hard-and-fast termination requirement after one year would best carry out the purpose of the injunctive relief."

" [1]Woman Hailed as Hero for Smashing Man's Meta Smart Glasses on Subway ," reads the headline at Futurism :

> As [2] Daily Dot reports , a New York subway rider has accused a woman of breaking his Meta smart glasses. "She just broke my Meta glasses," said the TikTok user, who goes by eth8n, in [3]a video that has since garnered millions of views.

>

> "You're going to be famous on the internet!" he shouted at her through the window after getting off the train. The accused woman, however, peered back at him completely unfazed, as if to say that he had it coming.

>

> "I was making a funny noise people were honestly crying laughing at," he claimed in the caption of a followup video. "She was the only person annoyed..." But instead of coming to his support, the internet wholeheartedly rallied behind the alleged perpetrator, celebrating the woman as a folk hero — and perfectly highlighting how the public feels about gadgets like Meta's smart glasses.

>

> "Good, people are tired of being filmed by strangers," one user commented.

>

> "The fact that no one else on the train is defending him is telling," another wrote...

>

> Others accused the man of fabricating details of the incident. "'People were crying laughing' — I've never heard a less plausible NYC subway story," one user wrote.

In a comment on TikTok, the man acknowledges he'd filmed her on the subway — it looks like he even [4]zoomed in . The man says then her other options were "asking nicely to not post it or blur my face".

He also warns that she could get arrested for breaking his glasses if he "felt like it". (And if he sees her again.) "I filed a claim with the police and it's a misdemeanor charge." A [5]subsequent video 's captions describe him unboxing new Meta smartglasses "and I'm about to do my thing again... no crazy lady can stop me now."

I'm imagining being mugged — and then telling the mugger "You're going to be internet famous!" But maybe that just shows how easy it is to weaponize smartglasses and their potential for vast public exposure.

"Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date," [1]reports Science Daily . "This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy consumption.

"The discovery also enhances the prospects for silicon-based quantum devices..."

> Scientists from the University of Warwick and the National Research Council of Canada have reported the highest "hole mobility" ever measured in a material that works within today's silicon-based semiconductor manufacturing.... The researchers created a nanometer-thin germanium epilayer on silicon that is placed under compressive strain. This engineered structure enables electric charge to move faster than in any previously known silicon-compatible material...

>

> The findings establish a promising new route for ultra-fast, low-power semiconductor components. Potential uses include quantum information systems, spin qubits, cryogenic controllers for quantum processors, AI accelerators, and energy-efficient servers designed to reduce cooling demands in data centers. This achievement also represents a significant accomplishment for Warwick's Semiconductors Research Group and highlights the UK's growing influence in advanced semiconductor materials research.

UPDATE (12/7): The New York Times clarifies today that the damage at Chernobyl [1]hasn't led to a rise in radiation levels :

> "If there was to be some event inside the shelter that would release radioactive materials into the space inside the New Safe Confinement, because this facility is no longer sealed to the outside environment, there's the potential for radiation to come out," said Shaun Burnie, a senior nuclear specialist at Greenpeace who has monitored nuclear power plants in Ukraine since 2022 and last visited Chernobyl on October 31. "I have to say I don't think that's a particularly serious issue at the moment, because they're not actively decommissioning the actual sarcophagus."

>

> The I.A.E.A. also said there was no permanent damage to the shield's load-bearing structures or monitoring systems. A spokesman for the agency, Fredrik Dahl, said in a text message on Sunday that radiation levels were similar to what they were before the drone hit.

But "A structure designed to prevent radioactive leakage at the defunct Chernobyl nuclear plant in Ukraine is no longer operational," [2]Politico reported Saturday , "after Russian drones targeted it earlier this year, the U.N.'s nuclear watchdog has found."

> [T]he large steel structure "lost its primary safety functions, including the confinement capability" when its outer cladding was set ablaze after being struck by Russian drones, according to a new report by the International Atomic Energy Agency. Beyond that, there was "no permanent damage to its load-bearing structures or monitoring systems," it said. "Limited temporary repairs have been carried out on the roof, but timely and comprehensive restoration remains essential to prevent further degradation and ensure long-term nuclear safety," IAEA Director General Rafael Mariano Grossi [3]said in astatement .

The Guardian [4]has pictures of the protective shield — incuding the damage from the drone strike. The shield is the world's largest movable land structure, [5]reports CNN :

> The IAEA, which has a permanent presence at the site, will "continue to do everything it can to support efforts to fully restore nuclear safety and security," Grossi said.... Built in 2010 and completed in 2019, it was designed to last 100 years and has played a crucial role in securing the site.

>

> The project cost €2.1 billion and was funded by contributions from more than 45 donor countries and organizations through the Chernobyl Shelter Fund, according to the European Bank for Reconstruction and Development, which in 2019 hailed the venture as "the largest international collaboration ever in the field of nuclear safety."

"First [1]the penny . Next, paper checks?" [2]asks CNN :

> When the U.S. Mint [3]stopped making pennies last month for the first time in 238 years, it drew a lot of attention. But there have been quiet moves to stop using paper checks as well. The government [4]stopped sending out most paper checks to recipients as of the end of September, part of an effort to fully modernize federal benefits payments. And on Thursday the Federal Reserve [5]put out a notice that suggested it is considering — but only considering — the "winding down" of checking services it now provides for banks.

>

> The central bank's statement said that as an alternative to winding down those services, it is mulling more investment in its check processing services, but noted that would come at a higher cost. But it is also considering not making any such investments, in order to keep costs roughly unchanged. That would lead to reduced reliability of those services going forward. "Over time, check use has steadily declined, digital payment methods have grown in availability and use, and check fraud has risen," said the notice from the Fed. "Also, the Reserve Banks will need to make substantial investments in their check infrastructure to continue providing the same level of check services going forward."

>

> [6]A report from the Federal Reserve Bank of Atlanta in June found that as of last year, more than 90% of surveyed consumers said they prefer to use something other than a check for paying bills, and just 6% paid by check. That's a sharp drop from the 18% of bills paid by checks as recently as 2017. Consumers also reported they view checks as second-worst for convenience and speed of payment, ahead of only money orders. And they're ranked as the least secure form of any payment other than cash.

>

> But even if it's true that options such as direct deposit, automatic bill paying and electronic payment systems such as Venmo, PayPal and Zelle have all reduced the need for traditional checks, paper checks are still an important part of the payment system. They make up about 5% of transactions and represent 21% of the value of all those payments, according to a statement from Michelle Bowman, the Fed's vice chair for supervision, who dissented from the Fed's Thursday statement.

To build three-wheeled, solar electric vehicles, Aptera has now launched its "validation" vehicle assembly line, [1]reports the San Diego Business Journal .

"The [2]validation line will set a technical foundation for the company's eventual low-volume assembly line, ensuring that manufacturing processes are optimized and refined, particularly for the company's composite body structure."

> To date, Aptera has produced three validation vehicles, two of which are in use driving around the San Diego region, with plans to build another 10 in the coming weeks as progress continues on the validation manufacturing line. "You learn things when you start to put miles on vehicles, putting 10s of thousands of miles on these validation vehicles and learning a lot from the durometer of the suspension, ride quality, spring rates and braking pressure," Aptera co-founder and co-CEO Chris Anthony said. "We've been able to incorporate a lot of the usability stuff back, but also, just as we've gone through the process of building these, a lot of order-of-operation stuff that's educated us on what's going to make for the best initial assembly lines," he added....

>

> Aptera made its [3]public debut on October 16, with the company's executive team participating in [4]the Nasdaq closing bell ceremony that evening . Shares of SEV have hovered between $6.50 and $8.50 for much of the company's first month on the exchange. The company's equity line of credit also took effect in mid-November... expected to aid in Aptera generating at least a portion of the $65 million the company has said it will need to complete validation manufacturing and begin low-volume production for customers. Aptera previously raised some $135 million from more than 17,000 investors in what the company touts as the most successful crowdfunding effort of all time, but Anthony argued Aptera will soon need to invest larger sums of capital to scale its production needs.

>

> "Publicly listing the company gives us a lot more funding mechanisms to get into production," he said. "So just having access to the public markets, public liquidity and the kind of instruments and tools that banks offer to public companies, it just seemed like now is the right time." Alongside the IPO, Aptera made its formal transition to a Public Benefit Corporation, giving the company a legal obligation to consider its effect on employees, communities and customers in addition to the profit motives of its shareholders.

California's state government also awarded Aptera $21 million "to support its push toward scaled manufacturing," the article points out.

It also notes that Aptera's vehicles "are technically classified as motorcycles rather than standard passenger cars, presenting a potentially cheaper alternative for consumers on the hunt for an electric vehicle."

Today America's college professors "struggle to accommodate the many students with an official disability designation," [1]reports the Atlantic , "which may entitle them to extra time, a distraction-free environment, or the use of otherwise-prohibited technology."

Their staff writer argues these accommodations "have become another way for the most privileged students to press their advantage."

> [Over the past decade and a half] the share of students at selective universities who qualify for accommodations — often, extra time on tests — has grown at a breathtaking pace. At the University of Chicago, the number has more than tripled over the past eight years; at UC Berkeley, it has nearly quintupled over the past 15 years. The increase is driven by more young people getting diagnosed with conditions such as [2]ADHD , [3]anxiety , and [4]depression , and by universities making the process of getting accommodations easier. The change has occurred disproportionately at the most prestigious and expensive institutions. At Brown and Harvard, more than 20 percent of undergraduates are registered as disabled. At Amherst, that figure is 34 percent. Not all of those students receive accommodations, but researchers told me that most do. The schools that enroll the most academically successful students, in other words, also have the largest share of students with a disability that could prevent them from succeeding academically. "You hear 'students with disabilities' and it's not kids in wheelchairs," one professor at a selective university, who requested anonymity because he doesn't have tenure, told me. "It's just not. It's rich kids getting extra time on tests...."

>

> Recently, mental-health issues have joined ADHD as a primary driver of the accommodations boom. Over the past decade, the number of young people diagnosed with depression or anxiety has exploded. L. Scott Lissner, the ADA coordinator at Ohio State University, told me that 36 percent of the students registered with OSU's disability office have accommodations for mental-health issues, making them the largest group of students his office serves. Many receive testing accommodations, extensions on take-home assignments, or permission to miss class. Students at Carnegie Mellon University whose severe anxiety makes concentration difficult might get extra time on tests or permission to record class sessions, Catherine Samuel, the school's director of disability resources, told me. Students with social-anxiety disorder can get a note so the professor doesn't call on them without warning... Some students get approved for housing accommodations, including single rooms and emotional-support animals. Other accommodations risk putting the needs of one student over the experience of their peers. One administrator told me that a student at a public college in California had permission to bring their mother to class. This became a problem, because the mom turned out to be an enthusiastic class participant. Professors told me that the most common — and most contentious — accommodation is the granting of extra time on exams...

>

> Several of the college students I spoke with for this story said they knew someone who had obtained a dubious diagnosis... The surge itself is undeniable. Soon, some schools may have more students receiving accommodations than not, a scenario that would have seemed absurd just a decade ago. Already, at one law school, 45 percent of students receive academic accommodations. Paul Graham Fisher, a Stanford professor who served as co-chair of the university's disability task force, told me, "I have had conversations with people in the Stanford administration. They've talked about at what point can we say no? What if it hits 50 or 60 percent? At what point do you just say 'We can't do this'?" This year, 38 percent of Stanford undergraduates are registered as having a disability; in the fall quarter, 24 percent of undergraduates were receiving academic or housing accommodations.

What happened when a school in Los Angeles gave a sixth grader an iPad for use throughout the school day? "He used the iPad during school to watch YouTube and participate in Fortnite video game battles," [1]reports NBC News .

His mother has now launched a coalition of parents called Schools Beyond Screens "organizing in WhatsApp groups, petition drives and actions at school board meetings and demanding meetings with district administrators, pressuring them to pull back on the school-mandated screen time."

> Los Angeles Unified is the first district of its size to face an organized — and growing — campaign by parents demanding that schools pull back on mandatory screen time. The discontent in Los Angeles Unified, the second-largest school district in the country, reflects a [2]growing unease nationally about the amount of time children spend learning through screens in classrooms. While a [3]majority of states prohibit children from using cellphones in class, 88% of schools provide students with personal devices, according to the [4]National Center for Education Statistics, often Chromebook laptops or iPads . The parents hope getting a district that has over 409,000 students across nearly 800 schools to change how it approaches screen time would send a signal across public school districts to pull back from a yearslong effort to digitize classrooms....

>

> [In the Los Angeles school district] Students in grade levels as low as kindergarten are provided iPads, and some schools require them to take the tablets home. Some teachers have allowed students to opt out of the iPad-based assignments, but other parents say they've been told that they can't. Parents can also opt their children out of [5]having access to YouTube and [6]several other Google products ... The billion-dollar 2014 initiative to give tablet computers to everyone [7]became a scandal after the bidding process appeared to heavily favor Apple, and it faced criticism once it became clear that students could bypass security protocols and that [8]few teachers used the tablets. Currently, the district leaves it up to individual schools to decide whether they want students to take home iPads or Chromebooks every day and how much time they spend on them in class...

>

> Around 300 parents attended listening sessions the district held last month about technology in the classroom. Nearly all who spoke criticized how much screen time schools gave their children in class, pointing to ways their behavior and grades suffered as students watched YouTube and played Minecraft... Several also asked district officials to explain why children as young as kindergartners were asked to [9]sign a form to use devices in which they promised they would honor intellectual property law and refrain from meeting people in person whom they met online. "Is it possible for children to meet people over the internet on school-issued devices?" one father asked. The district officials declined to answer, saying it was meant to be a listening session.

In 2022, Los Angeles Unified started requiring students to complete benchmark assessments on educaitonal software i-Ready, the article points out, which generates unique questions for each students. "But parents and teachers are unable to see what children are asked, in part because the company that makes the program considers them proprietary information..."

One teacher says his school's administartors are requiring him to use i-Ready even though it doesn't have any material for the science class he's actually teaching. He's also noticed some students will use answers from AI chatbots, bypassing the school's monitoring software by creating alternate user profiles. But the monitoring software company suggests the school misconfigured their software's settings, adding "More commonly, when students attempt to bypass filtering or monitoring, they do so by using proxies."
