A Russian-speaking hacking group obtained access to the email addresses of about 632,000 US federal employees at the departments of Defense and Justice as part of the sprawling MOVEit hack last summer, according to a report on the wide-ranging attack obtained through a Freedom of Information Act request. From a report: The report, by the US Office of Personnel Management, provides new details about a cyberattack in which hackers exploited flaws in MOVEit, a popular file-transfer tool. Federal cybersecurity officers previously confirmed that government agencies were compromised by the attack but have provided little information on the scope of the attack, nor did they name the agencies affected.

The Office of Personnel Management, in a July report on the incident submitted to a congressional committee, said an unauthorized actor obtained access to government email addresses, links to government employee surveys administered by OPM and internal OPM tracking codes. The impacted employees were at the Department of Justice and various parts of the Defense Department: the Air Force, Army, US Army Corps of Engineers, the Office of the Secretary of Defense, the Joint Staff and Defense Agencies and Field Activities.

Microsoft’s dedicated OS for embedded and pocket devices, Windows CE, has reached the end of its support lifetime. From a report: Windows CE — and there’s never been an official explanation of what the WinCE-inducing name stood for — debuted in November 1996, just a few months after Windows NT 4, the first version of NT with the Explorer desktop from Windows 95. Earlier this month, as reported by HPC Factor, the last ever version, CE 8, branded Compact Embedded 2013, reached its end of support.

In 2011, Microsoft said it would be replaced by a unified platform based on Windows 8, but we know how well that went down. By 2020, the official migration path was set — to a container on top of Win10 IoT. Its fortunes have always fluctuated. In 1999, we asked does MS care about WinCE? By 2003, we reported that eTForecasts said it would outship PCs. Indirectly, the researchers were right — smartphones did end up massively outselling PCs. They just weren’t Microsoft ones.

Western Digital said on Monday it would spin off its flash memory business that has been grappling with a supply glut after talks of merging the unit with Japan’s Kioxia stalled. From a report: The split will leave the data storage products maker with its traditional hard-disk drive business and create two publicly traded firms, giving into demands from activist investor Elliott. The move clears years of uncertainty over Western Digital’s flash memory unit that was built through its $19 billion purchase of SanDisk in 2016 and caters to the smartphone and computer industries. Demand for flash chips has slumped after the pandemic, leaving the market awash in supply and increasing the pressure on chipmakers to consolidate. Since 2021, Western Digital and its manufacturing partner Kioxia have been in talks for a merger that would create a company that controls a third of the global NAND flash market.

Google Chief Executive Sundar Pichai took the stand Monday in the tech giant’s antitrust trial, a pivotal moment in a case that could result in major changes to the company’s search engine. From a report: Pichai described Google’s search dominance as the result of its innovation and early investment in its Chrome browser. “We realized early on that browsers are critical to how people are able to navigate and use the web,” Pichai said during questioning by Google lawyer John Schmidtlein.

“It became very clear early on that if you make the user’s experience better, they would use the web more, they would enjoy using the web more, and they would search more in Google as well,” Pichai said. […] The nonjury trial is being heard by U.S. District Judge Amit Mehta, who could ultimately order a breakup or other changes to Google’s business practices. Schmidtlein, Google’s lead counsel, questioned Pichai about the deal at the heart of the case: the search giant’s contract with Apple that makes it the default search engine on Apple’s Safari web browser. The Apple deal “makes it very, very seamless and easy for users to use our services,” Pichai said. “We know that making it the default will lead to increased usage of our products and services, particularly Google search in this case. So there is clear value in that and that’s what we were looking for.”

An anonymous reader shares a report: PFAS stands for “per- and polyfluoroalkyl substances,” a family of upwards of 15,000 or more human-made and incredibly durable chemical compounds that have been used in countless industrial and consumer applications for decades. Firefighting foams, waterproof hiking boots, raincoats, nonstick frying pans, dental floss, lipstick, and even the ink used to label packaging — all can contain PFAS. The compounds are ubiquitous in drinking water and soil, even migrating to Arctic sea ice. PFAS are called forever chemicals because once present in the environment, they do not degrade or break down. They accumulate, are transferred throughout the watershed, and ultimately persist.
The quest to reduce the amount of PFAS in the environment is what led me to an industrial park in a southern suburb of Grand Rapids, Michigan. The jar of PFAS concentrate in my hand is part of a demonstration arranged by my hosts, Revive Environmental, during a tour of the company’s PFAS destruction site, one of the first in the country to operate commercially and at scale. A few yards in front of me sits the company’s PFAS “Annihilator” in a white shipping container.

The Annihilator represents just one of several technologies now vying to break down and destroy PFAS. These span the gamut from established processes like electrochemical oxidation and supercritical water oxidation to emerging techniques relying on ultraviolet light, plasma, ultrasound, or catalyst-driven thermal processes. Some are deployed in field tests. Other companies are actively running pilot programs, many with various divisions of the US Department of Defense and other government agencies. And many other technologies are still undergoing laboratory research. There’s good reason for this. Not only are PFAS everywhere around us; they’re also in us. Humans can’t break down PFAS, and our bodies struggle to clear them from our systems. Studies suggest they’re in my blood and yours — the majority of Americans,’ in fact — and they have been linked to increased risks of kidney and testicular cancer, decreased infant birthweights, and high blood pressure. And that’s only what we know about now: researchers continue to grapple with the full impacts of PFAS on human and environmental health.

OpenAI is rolling out new beta features for ChatGPT Plus members right now. Subscribers have reported that the update includes the ability to upload files and work with them, as well as multimodal support. From a report: Basically, users won’t have to select modes like Browse with Bing from the GPT-4 dropdown — it will instead guess what they want based on context. The new features bring a dash of the office features offered by its ChatGPT Enterprise plan to the standalone individual chatbot subscription. I don’t seem to have the multimodal update on my own Plus plan, but I was able to test out the Advanced Data Analysis feature, which seems to work about as expected. Once the file is fed to ChatGPT, it takes a few moments to digest the file before it’s ready to work with it, and then the chatbot can do things like summarize data, answer questions, or generate data visualizations based on prompts.

The UK government confirmed plans to regulate cryptoasset activities more strictly, bringing them under the same regime as traditional financial services. From a report: The government intends to proceed with legislation in 2024 to implement the changes, according to a Treasury announcement on Monday, responding to a consultation it launched earlier this year. The plans include a mandate for crypto exchanges to write detailed requirements on admission standards and disclosures for token issuers when listing new assets. This could include information about a token’s underlying code, known vulnerabilities and risks.

The UK’s push to regulate crypto is part of a wider effort by Prime Minister Rishi Sunak to attract more digital-asset businesses and investment to the country, while at the same time protecting consumers. Crypto firms have long complained that a lack of clear rules has made it hard for them to operate in the UK. “We must make the UK a place where cryptoasset firms have the clarity needed to invest and innovate, and where customers have the protections necessary for confidently using these technologies,” said City Minister Andrew Griffith. “The UK is the obvious choice for starting and scaling a cryptoasset business.”

President Joe Biden signed a wide-ranging executive order on artificial intelligence Monday, setting the stage for some industry regulations and funding for the U.S. government to further invest in the technology. From a report: The order is broad, and its focuses range from civil rights and industry regulations to a government hiring spree. In a media call previewing the order Sunday, a senior White House official, who asked to not be named as part of the terms of the call, said AI has so many facets that effective regulations have to cast a wide net. “AI policy is like running into a decathlon, and there’s 10 different events here,” the official said. “And we don’t have the luxury of just picking ‘we’re just going to do safety’ or “we’re just going to do equity’ or ‘we’re just going to do privacy.’ You have to do all of these things.”

The official also called for “significant bipartisan legislation” to further advance the country’s interests with AI. Senate Majority Leader Chuck Schumer, D-N.Y., held a private forum in September with industry leaders but has yet to introduce significant AI legislation. Some of the order builds on a previous nonbinding agreement that seven of the top U.S. tech companies developing AI agreed to in July, like hiring outside experts to probe their systems for weaknesses and sharing their critical findings. The order leverages the Defense Production Act to legally require those companies to share safety test results with the federal government.

The Wall Street Journal reports that more than three million Americans have now had a total of $127 billion in student loans flagged for cancellation. (Which for 3 million would average out to over $40,000 apiece).

Interestingly, the article notes this happened despite a set back for forgiveness in America’s highest court this June:

The high court ruled that the Biden administration couldn’t cancel hundreds of billions of dollars for tens millions of student-loan holders, reasoning that the authority for such a broad-based policy doesn’t exist under the law. While that closed one path, Biden tapped a variety of different tools that no previous president had ever used to this extent. Since taking office in 2021, the Biden administration has arranged to cancel loans equal to around 30% of the total projected cost of its blocked mass cancellation plan.

Wikipedia defines LIGO as “a large-scale physics experiment and observatory designed to detect cosmic gravitational waves.” (It stands for Laser Interferometer Gravitational-Wave Observatory — that is, measuring the interference caused by superimposed waves.)

Now Science Alert reports:
A technique for squeezing light in the arms of LIGO’s interferometer has allowed its measurements to cross the quantum barrier.
For LIGO, it’s a bold new realm of sensitivity, giving the gravitational wave detector the ability to find 60% more dead star mergers than the rate of its previous run, which was around one or two detections every week or so… “Now that we have surpassed this quantum limit, we can do a lot more astronomy,” says physicist Lee McCuller of Caltech…

LIGO’s sensitivity was already absolutely jaw-dropping. The interferometer works by detecting ripples in space-time that are generated by colliding black holes and neutron stars, millions of billions to light-years away. These cause gravitational waves, like ripples in a pond. We can’t feel them; but they can be detected in miniscule deviations in the path of light down a long, long tunnel. These deviations are incredibly small, down to trillions of times smaller than a human hair. But once you get into subatomic scales — the quantum realm — LIGO’s abilities are hobbled. That’s because, on those unimaginably small scales, particles randomly pop in and out of space, creating a constant background hiss of quantum noise that’s louder than any signal.

Frequency-dependent squeezing is a way of amplifying the signals to be ‘louder’ than the quantum noise… If you pinch a property of light, such as amplitude (or power), other properties, such as frequency, can be measured more accurately… [T]he light can be squeezed in multiple ways to amplify the frequency of the gravitational waves the scientists are looking for… “We’ve known for a while how to write down the equations to make this work, but it was not clear that we could actually make it work until now. It’s like science fiction,” says physicist Rana Adhikari of Caltech…

This means we’re likely to see a significant uptick in the number of black hole and neutron star collisions we observe out there in the wider Universe.

“More developers are looking for or are open to a new job now compared to the last two years,” writes Stack Overflow’s senior analyst for market research and insights — citing the results of their latest survey of developers in 107 different countries.

“More than 1,000 developers responded to this year’s survey about jobs and 79% are at least considering new opportunities if not actively looking.”

New insights from these survey results show that new tech talent and late-career developers are both more likely to be looking. New developers have increasingly switched jobs compared to early- and mid-career developers in the last three years… Interest in looking for a new job drops as developers get older for new to mid-career (44 and younger) respondents (86% to 74%), but picks back up for those 55 to 64 (88%). Late-career developers acknowledge curiosity about other companies as their second top reason to look for a new job this year behind “better salary,” which all age groups rank as their top reason. Curiosity grew in importance for late-career developers since last year more than all other age groups (32% vs. 22%) and is more important to this group than reasons other groups ranked higher such as working with new technology and growth opportunities…

In our 2023 Developer Survey, we started asking about AI and the sentiment around it in our developer community; results were very similar when we checked in again through this pulse survey (70% are using AI or planning to). Developers may also feel less enthusiastic about learning opportunities now that AI tools are rapidly developing to help many be more productive in their jobs (30% cite this as the top benefit).

Other interesting findings from the survey:
Compared to the 2023 Developer Survey, 8% of developers have exited the technology industry and are increasingly filling roles in manufacturing and supply chain companies (11% vs. 7%) Technology is the industry most developers currently work in (46%), followed by manufacturing/supply chain (14%) and financial services (13%)
New tech talent is onboarding at as many jobs by 24 as those up to 10 years their senior and this rapid experience cycle could rival the knowledge and experience of those they report to.

Are face masks effective in stopping virus transmissions? CBS News re-visited the question Sunday on its news show 60 Minutes by sending their chief medical correspondent to interview Linsey Marr, a professor who specializes in aerosol science at Virginia Tech University.
Here’s a transcript from an excerpt posted on YouTube:

60 Minutes: Is there any doubt in your mind that masks prevent the person who’s wearing it from getting Covid — or at least, are helpful?

Professor Marr: I would say they are very helpful in reducing the chances that the person will get Covid. Because it’s reducing the amount of virus that you would inhale from the air around you.

It’s not going to guarantee that it’s going to protect you, because are masks are not 100% effective — we talk about N-95’s being 95% efficient at filtering out particles, if they’re properly fitted and everything, and so that’s in an ideal world. But even so, if you — instead of breathing in 100 virsues, I’m breathing in 20, because my mask was 80% effective? That’s a huge reduction, and that greatly reduces the chance that I’m going to become infected.

On the CBS News web site, they highlight this excerpt from the interview:
Early in the pandemic, some guidance from health professionals suggested that wearing a mask might actually lead to infection: A person might encounter a contaminated mask and then touch their eyes, nose, or mouth. But research in the ensuing years has shown that fear to be misplaced. “There wasn’t any evidence really that that happens,” Marr said.

Marr said her team aerosolized the coronavirus, pulled it through a mask, and then examined how much virus survived on the mask. The study reported some viral particle remained on some cloth masks, but no virus survived on the N95s or surgical masks. Marr’s team also touched artificial skin to masks and looked at how many virus particles transferred to the artificial skin. No infectious virus transferred.
“I hope the study kind of shows that it’s something we don’t need to worry about as much as we were told,” Marr said.

CBS gave their video interview the headline “Face mask effectiveness: What we know now” — and asked professor Marr for a definitive answer:

60 Minutes: There was a lot of controversy over whether or not masks worked at all. Were you able to show that they worked scientifically?

Professor Marr: We were able to show that they block particles that are the same size as those that carry the virus… What happens is the virus is being carried in the air, and it’s not just going straight through those holes. It has to weave around all these layers of fibers in there. As the air is going around the curves, the virus may crash into one of those fibers, and so then it’s trapped, or maybe it comes up close to the fiber and brushes against it. And the really small particles, like the virus by itself if it were by itself, would be small enough that it undergoes these random motions, because it’s getting bounced around by the gas molecules, and it ends up crashing into the fibers of the mask too.

So there was accumulating evidence — and there had been kind of a handful of papers before that, too, showing the same thing. That masks — even cloth masks — do something.

Long-time Slashdot reader destinyland writes: In 1994 the TV show Friends premiered, and its first season’s high ratings made it the 8th most-popular show. The next year Microsoft released Windows 95 — and filmed a promotional video for it with 25-year-old Matthew Perry and 26-year-old Jennifer Aniston.

“They’ll be taking you on an adventure in computing that takes place in the office of Microsoft chairman Bill Gates,” explains the video’s narrator, adding “Along the way, they meet a wacky bunch of propellor-heads…. And are introduced the top 25 features of Windows 95!”

It’s a journey back in time. (At one point the video refers to Windows as the operating system “with tens of millions of users.”) Their 30-minute segment — billed as “the world’s first cyber sitcom” — appears in an hour-long video introducing revolutionary features like the new “Start” button. Also demonstrated in Excel are the new minimize and maximize “features” in “the upper right-side of the window”. And the two actors marvel at the ability to type a filename that was longer than eight characters…

Watch for reminders that The Microsoft Windows 95 Video Guide was filmed nearly three decades ago. When the desktop appears after waking from screensaver mode, Perry notes that there’s “no messy DOS build-up.” And later the video reminds viewers that Windows 95 is compatible “with DOS games like Flight Simulator.” There’s also a brand new feature called “Windows Explorer” (which is described as “File Manager on steroids”), as well as a new “Find” option, and a brand new icon named “My Computer”. And near the end they pay a visit to the Microsoft Network — which was mostly a “walled garden” online service — described in the video as “your on-ramp to the information superhighway”.

The video even explains how Windows 95 “uses the right mouse button for what Microsoft calls power users.”

And by the end of it, Jennifer Anniston finds herself playing Space Cadet 3D pinball.

The seven industrial countries known as the “G7” — America, Canada, Japan, Germany, France, Italy, and Britain — will agree on a code of conduct Monday for companies developing advanced AI systems, reports Reuters.

The news comes “as governments seek to mitigate the risks and potential misuse of the technology,” Reuters reports — citing a G7 document.

The 11-point code “aims to promote safe, secure, and trustworthy AI worldwide and will provide voluntary guidance for actions by organizations developing the most advanced AI systems, including the most advanced foundation models and generative AI systems”, the G7 document said. It “is meant to help seize the benefits and address the risks and challenges brought by these technologies”.

The code urges companies to take appropriate measures to identify, evaluate and mitigate risks across the AI lifecycle, as well as tackle incidents and patterns of misuse after AI products have been placed on the market. Companies should post public reports on the capabilities, limitations and the use and misuse of AI systems, and also invest in robust security controls.

“The work started on Wayland,” the Linux Mint project announced in their monthly newsletter.

An anonymous reader shared this report from 9to5Linux about an upcoming new option in the Ubuntu-based distro:

Linux Mint 21.3 [planned for Christmas of 2023] will be the first Linux Mint release to offer a Wayland session, but in an experimental state. The default session will still be the X11 one, but users who want to try Wayland can do so by selecting the “Cinnamon on Wayland” session from the login screen.
“The Wayland session won’t be as stable as the default one. It will lack features and it will come with its own limitations. We won’t recommend it but you’ll be able to give it a shot if you want to and it’ll be there for interested people if they want to give us feedback,” said Linux Mint project leader Clement Lefebvre.

I said that “2024 is the year of the Wayland desktop”, but Clement Lefebvre doesn’t think Linux Mint needs Wayland support before 2026… By that time, I believe Xfce will also be fully Wayland compatible so that Linux Mint can fully switch to Wayland by default.

The newsletter says the 2026 target “leaves us two years to identify and to fix all the issues. It’s something we’ll continue to work on.
“Whenever it happens, assuming it does, we’ll consider switching defaults. We’ll use the best tools to do the job and provide the best experience. Today that means Xorg. Tomorrow it might mean Wayland. We’ll be ready and compatible with both.”

The Washington Post’s editorial board looks at America’s “net neutrality” debate.

But first they note that America’s communications-regulating FCC has “limited authority to regulate unless broadband is considered a ‘common carrier’ under the Telecommunications Act of 1996.”

The FCC under President Barack Obama moved to reclassify broadband so it could regulate broadband companies; the FCC under President Donald Trump reversed the change. Dismayed advocates warned the world that, without the protections in place, the internet would break. You’ll never guess what happened next: nothing. Or, at least, almost nothing. The internet did not break, and internet service providers for the most part did not block and they did not throttle.

All the same, today’s FCC, under Chairwoman Jessica Rosenworcel, has just moved to re-reclassify broadband. The interesting part is that her strongest argument doesn’t have much to do with net neutrality, but with some of the other benefits the country could see from having a federal watchdog keeping an eye on the broadband business… Broadband is an essential service… Yet there isn’t a single government agency with sufficient authority to oversee this vital tool. Asserting federal authority over broadband would empower regulation of any blocking, throttling or anti-competitive paid traffic prioritization that they might engage in. But it could also help ensure the safety and security of U.S. networks.

The FCC has, on national security grounds, removed authorization for companies affiliated with adversary states, such as China’s Huawei, from participating in U.S. telecommunications markets. The agency can do this for phone carriers. But it can’t do it for broadband, because it isn’t allowed to. Or consider public safety during a crisis. The FCC doesn’t have the ability to access the data it needs to know when and where there are broadband outages — much less the ability to do anything about those outages if they are identified. Similarly, it can’t impose requirements for network resiliency to help prevent those outages from occurring in the first place — during, say, a natural disaster or a cyberattack.

The agency has ample power to police the types of services that are becoming less relevant in American life, such as landline telephones, and little power to police those that are becoming more important every day.
The FCC acknowledges this power would also allow them to prohibit “throttling” of content. But the Post’s editorial also makes the argument that here in 2023 that’s “unlikely to have any major effect on the broadband industry in either direction… Substantial consequences have only become less likely as high-speed bandwidth has become less limited.”

“Scientists recently fired up the world’s smallest particle accelerator for the first time,” reports Space.com.

“The tiny technological triumph, which is around the size of a small coin, could open the door to a wide range of applications, including using the teensy particle accelerators inside human patients.”

The new machine, known as a nanophotonic electron accelerator (NEA), consists of a small microchip that houses an even smaller vacuum tube made up of thousands of individual “pillars.” Researchers can accelerate electrons by firing mini laser beams at these pillars. The main acceleration tube is approximately 0.02 inches (0.5 millimeter) long, which is 54 million times shorter than the 16.8-mile-long (27 kilometers) ring that makes up CERN’s Large Hadron Collider (LHC) in Switzerland — the world’s largest and most powerful particle accelerator… The inside of the tiny tunnel is only around 225 nanometers wide. For context, human hairs are 80,000 to 100,000 nanometers thick, according to the National Nanotechnology Institute.

In a new study, published Oct. 18 in the journal Nature, researchers from the Friedrich-Alexander University of Erlangen-Nuremberg (FAU) in Germany used the tiny contraption to accelerate electrons from an energy value of 28.4âkiloelectron volts to 40.7âkeV, which is an increase of around 43%. It is the first time that a nanophotonic electron accelerator, which was first proposed in 2015, has been successfully fired, the researchers wrote in a statement…

“For the first time, we really can speak about a particle accelerator on a [micro]chip,” study co-author Roy Shiloh, a physicist at FAU, said in the statement.

What they accomplished “was demonstrated almost simultaneously by colleagues at Stanford University,” according to the researchers’ statement. “Their results are currently under review, but can be viewed on a repository. The two teams are working together on the realization of the ‘Accelerator on a chip’ in a project funded by the Gordon and Betty Moore Foundation” in 2015.

Long-time Slashdot reader CJSHayward shares “an attempt at Python virtual shell.”

The home-brewed project “mixes your native shell with Python with the goal of letting you use your regular shell but also use Python as effectively a shell scripting language, as an alternative to your shell’s built-in scripting language… I invite you to explore and improve it!”

From the web site:

The Python Virtual Shell (pvsh or ‘p’ on the command line) lets you mix zsh / bash / etc. built-in shell scripting with slightly modified Python scripting. It’s kind of like Brython [a Python implementation for client-side web programming], but for the Linux / Unix / Mac command line…

The core concept is that all Python code is indented with tabs, with an extra tab at the beginning to mark Python code, and all shell commands (including some shell builtins) have zero tabs of indentation. They can be mixed line-by-line, offering an opportunity to use built-in zsh, bash, etc. scripting or Python scripting as desired.

The Python is an incomplete implementation; it doesn’t support breaking a line into multiple lines. Nonetheless, this offers a tool to fuse shell- and Python-based interactions from the Linux / Unix / Mac command line.
