Two Nights of Broken Sleep Can Make People Feel Years Older, Finds Study (theguardian.com) 43

Two nights of broken sleep are enough to make people feel years older, according to researchers, who said consistent, restful slumber was a key factor in helping to stave off feeling one's true age. From a report: Psychologists in Sweden found that, on average, volunteers felt more than four years older when they were restricted to only four hours of sleep for two consecutive nights, with some claiming the sleepiness made them feel decades older. The opposite was seen when people were allowed to stay in bed for nine hours, though the effect was more modest, with participants in the study claiming to feel on average three months younger than their real age after ample rest.

"Sleep has a major impact on how old you feel and it's not only your long-term sleep patterns," said Dr Leonie Balter, a psychoneuroimmunologist at the Karolinska Institute in Stockholm and first author on the study. "Even when you only sleep less for two nights that has a real impact on how you feel." Beyond simply feeling more decrepit, the perception of being many years older may affect people's health, Balter said, by encouraging unhealthy eating, reducing physical exercise, and making people less willing to socialise and engage in new experiences.

Boeing Chief Must Have Engineering Background, Emirates Boss Says (ft.com) 81

The chief of Emirates, one of Boeing's largest clients, has said the crisis-stricken US aircraft maker should ensure its new chief executive has engineering experience to restore safety standards (non-paywalled link). From a report: A day after Boeing chief executive Dave Calhoun announced he would step down, Sir Tim Clark also said he backed efforts by the US group's largest labour union to win a seat on the board. "To fix Boeing's issues the company needs a strong engineering lead as its head coupled to a governance model which prioritises safety and quality," Clark told the Financial Times on Tuesday.

"Some serious lateral thinking" was needed, the airline boss added. Boeing on Monday unveiled a wide-ranging reshuffle of its leadership in a bid to get to grips with an escalating reputational crisis after a 737 Max door panel blew off mid-flight in January. Calhoun, 66, is to leave at the end of the year, while board chair Larry Kellner said he would depart in May. Stan Deal, head of the commercial planes division since 2019, was immediately replaced by chief operating officer Stephanie Pope.

Microsoft Dev's 30-Year-Old Temporary Code Still Lingers in Windows 11 68

Dave Plummer, a former Microsoft developer, has shared the story behind the Format drive dialog box in Windows, which has remained unchanged for nearly three decades. According to Plummer, the dialog box was created as a temporary solution during the porting of code from Windows 95 to Windows NT, due to differences between the two operating systems. Plummer jotted down all the formatting options on a piece of paper and created a basic UI, intending it to be a placeholder until a more refined version could be developed. However, the intended UI improvement never materialized, and Plummer's temporary solution has persisted through numerous Windows versions, including the latest Windows 11.

Plummer also admitted that the 32GB limit on FAT volume size in Windows was an arbitrary decision he made at the time, which has since become a permanent constraint.

Submission + - Age Verification Laws Drag Us Back to the Dark Ages of the Internet (404media.co)

samleecole writes: In Texas, Montana, North Carolina, Virginia, Louisiana, Arkansas, Mississippi, and Utah, age verification laws require sites with more than one third adult content to force users to upload their driver’s license, passport, or other government-issued ID. Indiana and Idaho’s age verification laws will take effect on July 1, and bills are progressing in several more states.

The legislators passing these bills are doing so under the guise of protecting children, but what’s actually happening is a widespread rewiring of the scaffolding of the internet. They ignore long-established legal precedent that has said for years that age verification is unconstitutional, eventually and inevitably reducing everything we see online without impossible privacy hurdles and compromises to that which is not “harmful to minors.”

The people who live in these states, including the minors the law is allegedly trying to protect, are worse off because of it. So is the rest of the internet.

Judge Orders YouTube to Reveal Everyone Who Viewed A Video (mashable.com) 169

"If you've ever jokingly wondered if your search or viewing history is going to 'put you on some kind of list,' your concern may be more than warranted," writes Mashable : In now unsealed court documents reviewed by Forbes, Google was ordered to hand over the names, addresses, telephone numbers, and user activity of Youtube accounts and IP addresses that watched select YouTube videos, part of a larger criminal investigation by federal investigators.

The videos were sent by undercover police to a suspected cryptocurrency launderer... In conversations with the bitcoin trader, investigators sent links to public YouTube tutorials on mapping via drones and augmented reality software, Forbes details. The videos were watched more than 30,000 times, presumably by thousands of users unrelated to the case. YouTube's parent company Google was ordered by federal investigators to quietly hand over all such viewer data for the period of Jan. 1 to Jan. 8, 2023...

"According to documents viewed by Forbes, a court granted the government's request for the information," writes PC Magazine, adding that Google was asked "to not publicize the request." The requests are raising alarms for privacy experts who say the requests are unconstitutional and are "transforming search warrants into digital dragnets" by potentially targeting individuals who are not associated with a crime based simply on what they may have watched online.
That quote came from Albert Fox-Cahn, executive director at the Surveillance Technology Oversight Project, who elaborates in Forbes' article. "No one should fear a knock at the door from police simply because of what the YouTube algorithm serves up. I'm horrified that the courts are allowing this."

Say Hello To Biodegradable Microplastics? (ucsd.edu) 60

Long-time Slashdot reader HanzoSpam shared an announcement from the University of California San Diego.

The school's researchers teamed with materials-science company Algenesis to show "that their plant-based polymers biodegrade — even at the microplastic level — in under seven months." "We're trying to find replacements for materials that already exist, and make sure these replacements will biodegrade at the end of their useful life instead of collecting in the environment," stated Professor of Chemistry and Biochemistry Michael Burkart, one of the paper's authors and an Algenesis co-founder. "That's not easy."

"When we first created these algae-based polymers about six years ago, our intention was always that it be completely biodegradable," said another of the paper's authors, Robert Pomeroy, who is also a professor of chemistry and biochemistry and an Algenesis co-founder. "We had plenty of data to suggest that our material was disappearing in the compost, but this is the first time we've measured it at the microparticle level...."

"This material is the first plastic demonstrated to not create microplastics as we use it," said Stephen Mayfield, a paper coauthor, School of Biological Sciences professor and co-founder of Algenesis. "This is more than just a sustainable solution for the end-of-product life cycle and our crowded landfills. This is actually plastic that is not going to make us sick."

Creating an eco-friendly alternative to petroleum-based plastics is only one part of the long road to viability. The ongoing challenge is to be able to use the new material on pre-existing manufacturing equipment that was originally built for traditional plastic, and here Algenesis is making progress. They have partnered with several companies to make products that use the plant-based polymers developed at UC San Diego, including Trelleborg for use in coated fabrics and RhinoShield for use in the production of cell phone cases.

"When we started this work, we were told it was impossible," stated Burkart. "Now we see a different reality. There's a lot of work to be done, but we want to give people hope. It is possible."

Ask Slashdot: DuckDB Queries JSON with SQL. But Will AI Change Code Syntax? (pgrs.net) 12

Long-time Slashdot reader theodp writes: Among the amazing features of the in-process analytical database DuckDB, writes software engineer Paul Gross in DuckDB as the New jq, is that it has many data importers included without requiring extra dependencies. This means it can natively read and parse JSON as a database table, among many other formats. "Once I learned DuckDB could read JSON files directly into memory," Gross explains, "I realized that I could use it for many of the things where I'm currently using jq. In contrast to the complicated and custom jq syntax, I'm very familiar with SQL and use it almost daily."

The stark difference of the two programming approaches to the same problem — terse-but-cryptic jq vs. more-straightforward-to-most SQL — also raises some interesting questions: Will the use of Generative AI coding assistants more firmly entrench the status quo of the existing programming paradigms on whose codebases it's been trained? Or could it help bootstrap the acceptance of new, more approachable programming paradigms?

Had something like ChatGPT been around back in the Programming Windows 95 days, might people have been content to use Copilot to generate reams of difficult-to-maintain-and-enhance Windows C code using models trained on the existing codebases instead of exploring easier approaches to Windows programming like Visual BASIC?

Submission + - Feds Ordered Google To Unmask Certain YouTube Viewers, 'Terrifying' (forbes.com)

schwit1 writes: Police investigating suspected Bitcoin money laundering wanted info on viewers of certain tutorial videos viewed over 30,000 times, Forbes reported.

The court orders show the government telling Google to provide the names, addresses, telephone numbers and user activity for all Google account users who accessed the YouTube videos between January 1 and January 8, 2023. The government also wanted the IP addresses of non-Google account owners who viewed the videos.

The documents reportedly don’t reveal whether Google gave over the information.

The Matrix

It's 25 Years Later. Are We All Now Trapped in 'The Matrix'? (msn.com) 181

It was March 24, 1999 that The Matrix premiered, premembers the Wall Street Journal. "To rewatch The Matrix is to be reminded of how primitive our technology was just 25 years ago. We see computers with bulky screens, cellphones with keypads and a once-ubiquitous feature of our society known as 'pay phones,' central to the plot of the film."

But the article's headline warns that "25 Years Later, We're All Trapped in 'The Matrix'". [I]n a strange way, the film has become more relevant today than it was in 1999. With the rise of the smartphone and social media, genuine human interaction has dropped precipitously. Today many people, like Cypher, would rather spend their time in the imaginary realms offered by technology than engage in a genuine relationship with other human beings.

In the film, one of the representatives of the AI, the villainous Agent Smith, played by Hugo Weaving, tells Morpheus that the false reality of the Matrix is set in 1999 because that year was "the peak of your civilization. I say your civilization, because as soon as we started thinking for you it really became our civilization." Indeed, not long after "The Matrix" premiered, humanity hooked itself up to a matrix of its own. There is no denying that our lives have become better in many ways thanks to the internet and smartphones. But the epidemic of loneliness and depression that has swept society reveals that many of us are now walled off from one another in vats of our own making...

For today's dwellers in the digital cave, the path back into the light doesn't involve taking a pill, as in "The Matrix," or being rescued by a philosopher. We ourselves have the power to resist the extremes of the digital world, even as we remain linked to it. You can find hints of an unplugged "Zion" in the Sabbath tables of observant Jews, where electronic devices are forbidden, and in university seminars where laptops are banned so that students can engage with a text and each other.

Twenty-five years ago, "The Matrix" offered us a modern twist on Plato's cave. Today we are once again asking what it will take to find our way out of the lonely darkness, into the brilliance of other human souls in the real world.

Hackers Found a Way To Open Any of 3 Million Hotel Keycard Locks In Seconds (wired.com) 33

An anonymous reader quotes a report from Wired: When thousands of security researchers descend on Las Vegas every August for what's come to be known as "hacker summer camp," the back-to-back Black Hat and Defcon hacker conferences, it's a given that some of them will experiment with hacking the infrastructure of Vegas itself, the city's elaborate array of casino and hospitality technology. But at one private event in 2022, a select group of researchers were actually invited to hack a Vegas hotel room, competing in a suite crowded with their laptops and cans of Red Bull to find digital vulnerabilities in every one of the room's gadgets, from its TV to its bedside VoIP phone. One team of hackers spent those days focused on the lock on the room's door, perhaps its most sensitive piece of technology of all. Now, more than a year and a half later, they're finally bringing to light the results of that work: a technique they discovered that would allow an intruder to open any of millions of hotel rooms worldwide in seconds, with just two taps.

Today, Ian Carroll, Lennert Wouters, and a team of other security researchers are revealing a hotel keycard hacking technique they call Unsaflok. The technique is a collection of security vulnerabilities that would allow a hacker to almost instantly open several models of Saflok-brand RFID-based keycard locks sold by the Swiss lock maker Dormakaba. The Saflok systems are installed on 3 million doors worldwide, inside 13,000 properties in 131 countries. By exploiting weaknesses in both Dormakaba's encryption and the underlying RFID system Dormakaba uses, known as MIFARE Classic, Carroll and Wouters have demonstrated just how easily they can open a Saflok keycard lock. Their technique starts with obtaining any keycard from a target hotel -- say, by booking a room there or grabbing a keycard out of a box of used ones -- then reading a certain code from that card with a $300 RFID read-write device, and finally writing two keycards of their own. When they merely tap those two cards on a lock, the first rewrites a certain piece of the lock's data, and the second opens it.

Dormakaba says that it's been working since early last year to make hotels that use Saflok aware of their security flaws and to help them fix or replace the vulnerable locks. For many of the Saflok systems sold in the last eight years, there's no hardware replacement necessary for each individual lock. Instead, hotels will only need to update or replace the front desk management system and have a technician carry out a relatively quick reprogramming of each lock, door by door. Wouters and Carroll say they were nonetheless told by Dormakaba that, as of this month, only 36 percent of installed Safloks have been updated. Given that the locks aren't connected to the internet and some older locks will still need a hardware upgrade, they say the full fix will still likely take months longer to roll out, at the very least. Some older installations may take years.

Cloud Software Group Snubs GPL Obligations, Say Critics (theregister.com) 31

An anonymous reader shares a report: Even if you decide to stop offering free editions, you don't get to stop providing the source code to FOSS, users of JasperReports Server are complaining. Cloud Software Group -- the post-merger offspring of Citrix and Tibco -- has decided to withdraw the community edition of its JasperReports Server. Now all you can get is the commercial edition, with a 30-day free trial. Effectively, this seems like a similar tactic to Red Hat's unpopular changes to the way that the RHEL source code is distributed. Some of the JasperReports source code is still on Github, but not everything. The JasperSoft community website has the grumbling of unhappy users -- as does Reddit.

One user on the community website commented: "Are you aware Jasper Server CE was under the Affero GPL, and you can't delete everything? "You cannot just change the license of the previous versions and call it a day. I mean, we the users, have the right to fork it using the same license or a compatible one," the user protested. JasperSoft has been developing its reporting tools in the open for well over a decade -- the Reg was reporting on it nearly twenty years ago. Tibco acquired the company for some $185 million in 2014. We're not certain that things are going very well for the new outfit. Early last year, the merger was followed by a round of job losses, and the company has also more recently doubled its prices on some offerings.

Modern Web Bloat Means Some Pages Load 21MB of Data (tomshardware.com) 110

Christopher Harper reports via Tom's Hardware: Earlier this month, Danluu.com released an exhaustive 23-page analysis/op-ed/manifesto on the current status of unoptimized web pages and web app performance, finding that just loading a web page can even bog down an entry-level device that can run the popular game PUBG at 40 fps. In fact, the Wix webpage requires loading 21MB of data for one page, while the more famous websites Patreon and Threads load 13MB of data for one page. This can result in slow load times that reach up to 33 seconds or, in some cases, result in the page failing to load at all.

As the testing above shows, some of the most brutally intensive websites include the likes of... Quora, and basically every major social media platform. Newer content production platforms like Squarespace and newer Forum platforms like Discourse also have significantly worse performance than their older counterparts, often to the point of unusability on some devices. The Tecno S8C, one of the prominent entry-level phones common in emerging markets, is one particularly compelling test device that stuck. The device is actually quite impressive in some ways, including its ability to run PlayerUnknown's Battlegrounds Mobile at 40 FPS -- but the same device can't even run Quora and experiences nigh-unusable lag when scrolling on social media sites.

That example is most likely the best summation of the overall point, which is that modern web and app design is increasingly trending toward an unrealistic assumption of ever-increasing bandwidth and processing. Quora is a website where people answer questions -- there is absolutely no reason any of these websites should be harder to run than a Battle Royale game.

Social Psychologist Urges 'End the Phone-Based Childhood Now' (msn.com) 203

"The environment in which kids grow up today is hostile to human development," argues Jonathan Haidt, a social psychologist and business school ethics professor, saying that since the early 2010s, "something went suddenly and horribly wrong for adolescents."

The Atlantic recently published an excerpt from his book The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness.: By a variety of measures and in a variety of countries, the members of Generation Z (born in and after 1996) are suffering from anxiety, depression, self-harm, and related disorders at levels higher than any other generation for which we have data... I think the answer can be stated simply, although the underlying psychology is complex: Those were the years when adolescents in rich countries traded in their flip phones for smartphones and moved much more of their social lives online — particularly onto social-media platforms designed for virality and addiction. Once young people began carrying the entire internet in their pockets, available to them day and night, it altered their daily experiences and developmental pathways across the board. Friendship, dating, sexuality, exercise, sleep, academics, politics, family dynamics, identity — all were affected...

There's an important backstory, beginning as long ago as the 1980s, when we started systematically depriving children and adolescents of freedom, unsupervised play, responsibility, and opportunities for risk taking, all of which promote competence, maturity, and mental health. But the change in childhood accelerated in the early 2010s, when an already independence-deprived generation was lured into a new virtual universe that seemed safe to parents but in fact is more dangerous, in many respects, than the physical world. My claim is that the new phone-based childhood that took shape roughly 12 years ago is making young people sick and blocking their progress to flourishing in adulthood. We need a dramatic cultural correction, and we need it now...

A simple way to understand the differences between Gen Z and previous generations is that people born in and after 1996 have internal thermostats that were shifted toward defend mode. This is why life on college campuses changed so suddenly when Gen Z arrived, beginning around 2014. Students began requesting "safe spaces" and trigger warnings. They were highly sensitive to "microaggressions" and sometimes claimed that words were "violence." These trends mystified those of us in older generations at the time, but in hindsight, it all makes sense. Gen Z students found words, ideas, and ambiguous social encounters more threatening than had previous generations of students because we had fundamentally altered their psychological development.

The article argues educational scores also began dropping around 2012, while citing estimates that America's average teenager spends seven to nine hours a day on screen-based activities. "Everything else in an adolescent's day must get squeezed down or eliminated entirely to make room for the vast amount of content that is consumed... The main reason why the phone-based childhood is so harmful is because it pushes aside everything else." (For example, there's "the collapse of time spent interacting with other people face-to-face.")

The article warns of fragmented attention, disrupted learning, social withdrawal, and "the decay of wisdom and the loss of meaning." ("This rerouting of enculturating content has created a generation that is largely cut off from older generations and, to some extent, from the accumulated wisdom of humankind, including knowledge about how to live a flourishing life.") Its proposed solution?
  • No smartphones before high school
  • No social media before 16
  • Phoneâfree schools
  • More independence, free play, and responsibility in the real world

"We didn't know what we were doing in the early 2010s. Now we do. It's time to end the phone-based childhood."
