How SEC Mobile Phones Can Signal an Imminent Stock Price Drop

Slashdot - Fri, 2024-09-13 06:30
Mobile phone location data has linked site visits by US securities watchdogs to the headquarters of companies with measurable drops in their share prices -- even when no enforcement action is taken. From a report: When insiders sold shares right around a non-public visit by staff from the Securities and Exchange Commission, they avoided average losses of 4.9 per cent in the three months after the visit, according to a study led by researchers at four Midwestern universities. By matching commercially available data with share price moves, the study offers a window into the secretive world of securities enforcement beyond publicly announced cases. It also raises questions about the rules around insider trading. "Maybe we should be thinking about what the rules are when the SEC shows up," said Marcus Painter, assistant professor of finance at Saint Louis University and one of the authors. The research used geolocation data to identify mobile phones that spent significant amounts of time at the SEC's various offices around the country. They then tracked those phones to corporate headquarters around the world in the 12-month period right before Covid-19 lockdowns led to extensive working from home.

Court Clears Researchers of Defamation For Identifying Manipulated Data

Slashdot - Fri, 2024-09-13 05:30
An anonymous reader quotes a report from Ars Technica: Earlier this year, we got a look at something unusual: the results of an internal investigation conducted by Harvard Business School that concluded one of its star faculty members had committed research misconduct. Normally, these reports are kept confidential, leaving questions regarding the methods and extent of data manipulations. But in this case, the report became public because the researcher had filed a lawsuit that alleged defamation on the part of the team of data detectives that had first identified potential cases of fabricated data, as well as Harvard Business School itself. Now, the court has ruled (PDF) on motions to dismiss the case. While the suit against Harvard will go on, the court has ruled that evidence-backed conclusions regarding fabricated data cannot constitute defamation -- which is probably a very good thing for science. The researchers who had been sued, Uri Simonsohn, Leif Nelson, and Joe Simmons, run a blog called Data Colada where, among other things, they note cases of suspicious-looking data in the behavioral sciences. As we detailed in our earlier coverage, they published a series of blog posts describing an apparent case of fabricated data in four different papers published by the high-profile researcher Francesca Gino, a professor at Harvard Business School. The researchers also submitted the evidence to Harvard, which ran its own investigation that included interviewing the researchers involved and examining many of the original data files behind the paper. In the end, Harvard determined that research misconduct had been committed, placed Gino on administrative leave and considered revoking her tenure. Harvard contacted the journals where the papers were published to inform them that the underlying data was unreliable. Gino then filed suit alleging that Harvard had breached their contract with her, defamed her, and interfered with her relationship with the publisher of her books. She also added defamation accusations against the Data Colada team. Both Harvard and the Data Colada collective filed a motion to have all the actions dismissed, which brings us to this new decision. Harvard got a mixed outcome. This appears to largely be the result that the Harvard Business School adopted a new and temporary policy for addressing research misconduct when the accusations against Gino came in. This, according to the court, leaves questions regarding whether the university had breached its contract with her. However, most of the rest of the suit was dismissed. The judge ruled that the university informing Gino's colleagues that Gino had been placed on administrative leave does not constitute defamation. Nor do the notices requesting retractions sent to the journals where the papers were published. "I find the Retraction Notices amount 'only to a statement of [Harvard Business School]'s evolving, subjective view or interpretation of its investigation into inaccuracies in certain [data] contained in the articles,' rather than defamation," the judge decided. More critically, the researchers had every allegation against them thrown out. Here, the fact that the accusations involved evidence-based conclusions, and were presented with typical scientific caution, ended up protecting the researchers. The court cites precedent to note that "[s]cientific controversies must be settled by the methods of science rather than by the methods of litigation" and concludes that the material sent to Harvard "constitutes the Data Colada Defendants' subjective interpretation of the facts available to them." Since it had already been determined that Gino was a public figure due to her high-profile academic career, this does not rise to the standard of defamation. And, while the Data Colada team was pretty definitive in determining that data manipulation had taken place, its members were cautious about acknowledging that the evidence they had did not clearly indicate Gino was the one who had performed the manipulation. Finally, it was striking that the researchers had protected themselves by providing links to the data sources they'd used to draw their conclusions. The decision cites a precedent that indicates "by providing hyperlinks to the relevant information, the articles enable readers to review the underlying information for themselves and reach their own conclusions."

Hasbro CEO Claims All His Friends Use AI For D&D, Signal To Embrace It

Slashdot - Fri, 2024-09-13 01:20
Hasbro CEO Chris Cocks revealed at a Goldman Sachs conference that the company has been using AI in game development, including for "Dungeons & Dragons" and "Magic: The Gathering," and plans to integrate AI further into gameplay, despite previously banning AI-generated content. "Inside of development, we've already been using AI," Cocks said. "It's mostly machine-learning-based AI or proprietary AI as opposed to a ChatGPT approach. We will deploy it significantly and liberally internally as both a knowledge worker aid and as a development aid." Futurism reports: While the logistical aspects of the technology seem fairly par for the course in the world of out-of-touch CEOs over-relying on it, Cocks then suggested that it will become a part of D&D gameplay. "I'm probably more excited though about the playful elements of AI," he said. "I play with probably 30 or 40 people regularly. There's not a single person who doesn't use AI somehow for either campaign development or character development or story ideas. That's a clear signal that we need to be embracing it." After paying lip service to using AI "responsibly" and "paying creators for their work," Cocks then doubled down on his point. "The themes around using AI to enable user-generated content, using AI to streamline new player introduction, using AI for emergent storytelling -- I think you're going to see that not just our hardcore brands like D&D but also multiple of our brands," the Hasbro CEO said.

AMD's New Variable Graphics Memory Lets Laptop Users Reassign Their RAM To Gaming

Slashdot - Fri, 2024-09-13 00:40
AMD has introduced Variable Graphics Memory (VGM) for its AI 300 "Strix Point" laptops, allowing users to convert up to 75% of their system memory into dedicated VRAM via the AMD Adrenalin app, enhancing gaming performance for titles requiring more VRAM. The Verge reports: You might be wondering: does that extra video memory actually make a difference? Well, it depends on the game. Some games, like Alan Wake II, require as many as 6GB of VRAM and will throw errors at launch if you're short -- Steam Deck, Asus ROG Ally, and Lenovo Legion Go buyers have been tweaking their VRAM settings for some time to take games to the threshold of playability. But in early testing with the Asus Zenbook S 16, a Strix Point laptop that's already shipped with this feature, my colleague Joanna Nelius saw that turning it on isn't a silver bullet for every game. With 8GB of VRAM, the laptop played Control notably faster (65fps vs. 54fps), but some titles had smaller boosts, no boost, or even slight frame rate decreases.

Unhappy Workers May Reduce Global GDP By As Much As 9%, Gallup Estimates

Slashdot - Fri, 2024-09-13 00:00
An anonymous reader quotes a report from CNN: Employees' negative daily emotions and lack of well-being can ultimately hurt worker engagement -- and the economy, according to a new report released this week. Gallup, in its "State of the Global Workplace," estimates that low employee engagement costs the global economy $8.9 trillion, or 9% of global GDP. The report includes findings from its latest annual World Poll, which surveyed 128,278 employees in more than 140 countries last year. That poll found that roughly 20% of workers globally reported feeling lonely, angry or sad on a daily basis. And 41% on average say they feel stress. Those most likely to say they feel lonely were younger workers (22%), employees who worked remotely full-time (25%) and those who felt most disengaged on the job (31%). While work isn't always the cause of a person's negative daily emotions, employers should still be concerned. That's because work can either improve or worsen employees' well-being. On the one hand, the Gallup report noted, "when employees find their work and work relationships meaningful, employment is associated with high levels of daily enjoyment and low levels of all negative daily emotions. Notably, half of employees who are engaged at work are thriving in life overall." On the other, researchers found that being disengaged at work can negatively affect a person's wellbeing as much as -- or more than -- not having a job at all. "Employees who dislike their jobs tend to have high levels of daily stress and worry, as well as elevated levels of all other negative emotions," they wrote. "On many wellbeing items (stress, anger, worry, loneliness), being actively disengaged at work is equivalent to or worse than being unemployed." The poll found that last year only 23% of employees were engaged at work, unchanged from the year prior. Gallup defines an engaged employee as someone "highly involved in and enthusiastic about their work and workplace. They are psychological 'owners,' drive performance and innovation, and move the organization forward." But those who said they were not engaged rose by 3 percentage points to 62%. These are employees characterized as "psychologically unattached to their work and company. Because their engagement needs are not being fully met, they are putting time but not energy or passion into their work."

Billionaire and Engineer Conduct First Private Spacewalk In SpaceX Mission

Slashdot - Thu, 2024-09-12 23:21
Two astronauts, billionaire Jared Isaacman and SpaceX engineer Sarah Gillis, completed the world's first private spacewalk outside a SpaceX capsule, testing new spacesuits and procedures in a risky mission that pushes the boundaries of commercial spaceflight. Reuters reports: The astronauts on the Polaris Dawn mission went one at a time, each spending about 10 minutes outside the gumdrop-shaped Crew Dragon capsule on a tether, as Elon Musk's company again succeeded in pushing the boundaries of commercial spaceflight. Jared Isaacman, a pilot and the founder of electronic payments company Shift4, exited first, followed by SpaceX engineer Sarah Gillis, while crewmates Scott Poteet and Anna Menon watched from inside. The whole process, unfolding about 450 miles (730 km) above Earth, lasted an hour and 46 minutes. The four astronauts have been orbiting Earth since Tuesday's launch from Florida. Isaacman is bankrolling the Polaris mission, as he did his Inspiration4 flight with SpaceX in 2021. Streamed live on SpaceX's website, the mission tested trailblazing equipment including slim spacesuits and a process to fully depressurize the Crew Dragon cabin - technology that Musk hopes to advance for ambitious future private missions to Mars. "Back at home we all have a lot of work to do. But from here, Earth sure looks like a perfect world," Isaacman said after emerging from the spacecraft, silhouetted with the half-lit planet glittering below. It was one of the riskiest missions yet for SpaceX, the only private company that has proven to be capable of routinely sending people to and from Earth's orbit. "Today's success represents a giant leap forward for the commercial space industry and @NASA's long-term goal to build a vibrant U.S. space economy," said NASA Administrator Bill Nelson.

FDA Approves Apple AirPods As Hearing Aids

Slashdot - Thu, 2024-09-12 22:40
The FDA on Thursday approved the first hearing aid software for Apple's latest AirPods Pro earbuds. According to Apple, the feature will be pushed to eligible devices through a software update in the coming weeks. The Washington Post reports: The move, which comes two years after the FDA first approved over-the-counter hearing aids, could help more Americans with hearing loss start getting help, the FDA said in a statement. The feature works by amplifying some sounds, such as voices, while minimizing others, such as ambient noise. Users can take a hearing test in the Apple Health app, and their AirPods will adjust sound level automatically based on the results. The feature is only available on the AirPods Pro 2, which cost $249. The FDA says it tested Apple's hearing aid feature in a clinical study with 118 subjects who believed they had mild or moderate hearing loss. The study found that people who set up their AirPods using Apple's hearing test noticed similar benefits as people who had a professional set up the earbuds. Over-the-counter hearing aids are best for people with mild to moderate hearing loss, audiologists say, many of whom don't seek treatment. [...] However, consumer earbuds aren't a good solution for people with severe hearing loss, experts maintain, and most over-the-counter hearing devices will still require a trip to the audiologist for some fine tuning.

Music Industry's 1990s Hard Drives Are Dying

Slashdot - Thu, 2024-09-12 22:00
An anonymous reader quotes a report from Ars Technica: One of the things enterprise storage and destruction company Iron Mountain does is handle the archiving of the media industry's vaults. What it has been seeing lately should be a wake-up call: roughly one-fifth of the hard disk drives dating to the 1990s it was sent are entirely unreadable. Music industry publication Mix spoke with the people in charge of backing up the entertainment industry. The resulting tale is part explainer on how music is so complicated to archive now, part warning about everyone's data stored on spinning disks. "In our line of work, if we discover an inherent problem with a format, it makes sense to let everybody know," Robert Koszela, global director for studio growth and strategic initiatives at Iron Mountain, told Mix. "It may sound like a sales pitch, but it's not; it's a call for action." Hard drives gained popularity over spooled magnetic tape as digital audio workstations, mixing and editing software, and the perceived downsides of tape, including deterioration from substrate separation and fire. But hard drives present their own archival problems. Standard hard drives were also not designed for long-term archival use. You can almost never decouple the magnetic disks from the reading hardware inside, so that if either fails, the whole drive dies. There are also general computer storage issues, including the separation of samples and finished tracks, or proprietary file formats requiring archival versions of software. Still, Iron Mountain tells Mix that "If the disk platters spin and aren't damaged," it can access the content. But "if it spins" is becoming a big question mark. Musicians and studios now digging into their archives to remaster tracks often find that drives, even when stored at industry-standard temperature and humidity, have failed in some way, with no partial recovery option available. "It's so sad to see a project come into the studio, a hard drive in a brand-new case with the wrapper and the tags from wherever they bought it still in there," Koszela says. "Next to it is a case with the safety drive in it. Everything's in order. And both of them are bricks." "Optical media rots, magnetic media rots and loses magnetic charge, bearings seize, flash storage loses charge, etc.," writes Hacker News user abracadaniel in a discussion post about the article. "Entropy wins, sometimes much faster than you'd expect."

Microsoft To Revamp Windows Kernel Access for Security Vendors

Slashdot - Thu, 2024-09-12 20:49
Microsoft announced plans to modify Windows, enabling security vendors like CrowdStrike to operate outside the operating system's kernel. The move follows the July incident where a faulty CrowdStrike update caused widespread system failures. From a report: Microsoft says it has now "discussed the requirements and key challenges in creating a new platform which can meet the needs of security vendors" with partners like CrowdStrike, Broadcom, Sophos, and Trend Micro. [...] While Microsoft isn't directly saying it's going to close off access to the Windows kernel, it's clearly at the early stages of designing a security platform that can eventually move CrowdStrike and others out of the kernel. Microsoft last tried to close off access to the Windows kernel in Windows Vista in 2006, but it was met with pushback from cybersecurity vendors and regulators.

OpenAI Releases o1, Its First Model With 'Reasoning' Abilities

Slashdot - Thu, 2024-09-12 19:17
OpenAI has launched a new AI model, named "o1", designed for improved reasoning and problem-solving skills. o1, part of a new series of models and available in ChatGPT and the API, can tackle complex tasks in science, coding, and math more effectively than their predecessors. Notably, o1 models have shown promising results in standardized tests and coding competitions. While o1 models represent a significant advancement in AI capabilities, they currently lack features like web browsing and file uploading. The Verge adds: But it's also more expensive and slower to use than GPT-4o. OpenAI is calling this release of o1 a "preview" to emphasize how nascent it is. ChatGPT Plus and Team users get access to both o1-preview and o1-mini starting today, while Enterprise and Edu users will get access early next week. OpenAI says it plans to bring o1-mini access to all the free users of ChatGPT but hasn't set a release date yet. Developer access to o1 is really expensive: In the API, o1-preview is $15 per 1 million input tokens, or chunks of text parsed by the model, and $60 per 1 million output tokens. For comparison, GPT-4o costs $5 per 1 million input tokens and $15 per 1 million output tokens. The training behind o1 is fundamentally different from its predecessors, OpenAI's research lead, Jerry Tworek, tells me, though the company is being vague about the exact details. He says o1 "has been trained using a completely new optimization algorithm and a new training dataset specifically tailored for it."

Ex-Google Exec Said Goal Was To 'Crush' Competition, Trial Evidence Shows

Slashdot - Thu, 2024-09-12 18:50
A Google executive told colleagues the goal for the company's then-nascent online advertising business in 2009 was to "crush" rival advertising networks, according to evidence prosecutors presented at the tech titan's antitrust trial on Wednesday. From a report: The statements underscored the U.S. Department of Justice's claim that Google has sought to monopolize markets for publisher ad servers and advertiser ad networks, and tried to dominate the market for ad exchanges which sit in the middle. On the third day of the trial, prosecutors began to introduce evidence of how Google employees thought about the company's products at the time when the government alleges it set out to dominate the ad tech market. "We'll be able to crush the other networks and that's our goal," David Rosenblatt, Google's former president of display advertising, said of the company's strategy in late 2008 or early 2009, according to notes shown in court. Google denies the allegations, saying it faces fierce competition from rival digital advertising companies. Rosenblatt came to Google in 2008 when it acquired his former ad tech company, DoubleClick, and left the following year. The notes of his talk showed him discussing the advantages of owning technology on both sides and the middle of the market. "We're both Goldman and NYSE," he said, he said, according to the notes, referring to one of the world's biggest stock exchanges at the time and one of its biggest market makers. "Google has created what's comparable to the NYSE or London Stock Exchange; in other words, we'll do to display what Google did to search," Rosenblatt said.

Unity is Killing Its Controversial Runtime Fee

Slashdot - Thu, 2024-09-12 18:15
Unity is canceling the Runtime Fee and reverting back to its existing seat-based subscription model, albeit with a price increase for Unity Pro and Unity Enterprise users. From a report: The engine maker introduced the controversial levy around a year ago. Initially, the Runtime Fee sought to charge developers a per install tariff once projects had passed certain milestones. It was a decision that left many users reeling, resulting in a colossal backlash that ultimately forced the company to rework-but not ditch-the policy. The fallout, however, was enormous. A number of high-profile creators lambasted Unity and threatened to ditch the engine over what they felt was a huge betrayal of trust. Unity's inability to quickly resolve the issue and communicate effectively with customers only added fuel to that fire. Two weeks after the debacle, Unity CEO and president John Riccitiello departed the company. Unity Create boss Marc Whitten eventually followed suit. Unity is now attempting to course correct under the leadership of new CEO Matthew Bromberg, who hopes canceling the Runtime can reestablish a partnership "built on trust."

China's Startup Ecosystem Collapses as New Venture Formations Plunge 98%

Slashdot - Thu, 2024-09-12 16:44
China's once-booming venture capital industry is experiencing a severe downturn, with the number of new startups plummeting from 51,302 in 2018 to just 1,202 in 2023, according to data provider IT Juzi. This decline is starkly evident in science parks and innovation hubs across the country, where vacant offices and abandoned equipment have become commonplace, according to a stunning FT story. Industry insiders attribute the crisis to a combination of factors, including China's economic slowdown, heightened US-China tensions, and President Xi Jinping's policies targeting the tech sector. The government's anti-corruption drive and increased scrutiny of successful entrepreneurs have further dampened the private sector's enthusiasm. The funding landscape has shifted dramatically, with state-backed funds now dominating the market. This has led to more conservative investment strategies, favoring lower-risk sectors like advanced manufacturing over traditionally popular areas such as biotech and consumer technology. Founders face increasingly stringent terms, including personal liability for investments and asset checks. Many established VC firms are downsizing operations and exploring overseas opportunities.

As Quantum Computing Threats Loom, Microsoft Updates Its Core Crypto Library

Slashdot - Thu, 2024-09-12 15:00
An anonymous reader quotes a report from Ars Technica: Microsoft has updated a key cryptographic library with two new encryption algorithms designed to withstand attacks from quantum computers. The updates were made last week to SymCrypt, a core cryptographic code library for handing cryptographic functions in Windows and Linux. The library, started in 2006, provides operations and algorithms developers can use to safely implement secure encryption, decryption, signing, verification, hashing, and key exchange in the apps they create. The library supports federal certification requirements for cryptographic modules used in some governmental environments. Despite the name, SymCrypt supports both symmetric and asymmetric algorithms. It's the main cryptographic library Microsoft uses in products and services including Azure, Microsoft 365, all supported versions of Windows, Azure Stack HCI, and Azure Linux. The library provides cryptographic security used in email security, cloud storage, web browsing, remote access, and device management. Microsoft documented the update in a post on Monday. The updates are the first steps in implementing a massive overhaul of encryption protocols that incorporate a new set of algorithms that aren't vulnerable to attacks from quantum computers. [...] The first new algorithm Microsoft added to SymCrypt is called ML-KEM. Previously known as CRYSTALS-Kyber, ML-KEM is one of three post-quantum standards formalized last month by the National Institute of Standards and Technology (NIST). The KEM in the new name is short for key encapsulation. KEMs can be used by two parties to negotiate a shared secret over a public channel. Shared secrets generated by a KEM can then be used with symmetric-key cryptographic operations, which aren't vulnerable to Shor's algorithm when the keys are of a sufficient size. [...] The other algorithm added to SymCrypt is the NIST-recommended XMSS. Short for eXtended Merkle Signature Scheme, it's based on "stateful hash-based signature schemes." These algorithms are useful in very specific contexts such as firmware signing, but are not suitable for more general uses. Monday's post said Microsoft will add additional post-quantum algorithms to SymCrypt in the coming months. They are ML-DSA, a lattice-based digital signature scheme, previously called Dilithium, and SLH-DSA, a stateless hash-based signature scheme previously called SPHINCS+. Both became NIST standards last month and are formally referred to as FIPS 204 and FIPS 205. In Monday's post, Microsoft Principal Product Manager Lead Aabha Thipsay wrote: "PQC algorithms offer a promising solution for the future of cryptography, but they also come with some trade-offs. For example, these typically require larger key sizes, longer computation times, and more bandwidth than classical algorithms. Therefore, implementing PQC in real-world applications requires careful optimization and integration with existing systems and standards."

Voyager 1 Team Accomplishes Tricky Thruster Swap

Slashdot - Thu, 2024-09-12 12:00
fjo3 shares a report from NASA: Engineers working on NASA's Voyager 1 probe have successfully mitigated an issue with the spacecraft's thrusters, which keep the distant explorer pointed at Earth so that it can receive commands, send engineering data, and provide the unique science data it is gathering. After 47 years, a fuel tube inside the thrusters has become clogged with silicon dioxide, a byproduct that appears with age from a rubber diaphragm in the spacecraft's fuel tank. The clogging reduces how efficiently the thrusters can generate force. After weeks of careful planning, the team switched the spacecraft to a different set of thrusters. [...] Switching to different thrusters would have been a relatively simple operation for the mission in 1980 or even 2002. But the spacecraft's age has introduced new challenges, primarily related to power supply and temperature. The mission has turned off all non-essential onboard systems, including some heaters, on both spacecraft to conserve their gradually shrinking electrical power supply, which is generated by decaying plutonium. While those steps have worked to reduce power, they have also led to the spacecraft growing colder, an effect compounded by the loss of other non-essential systems that produced heat. Consequently, the attitude propulsion thruster branches have grown cold, and turning them on in that state could damage them, making the thrusters unusable. The team determined that the best option would be to warm the thrusters before the switch by turning on what had been deemed non-essential heaters. However, as with so many challenges the Voyager team has faced, this presented a puzzle: The spacecraft's power supply is so low that turning on non-essential heaters would require the mission to turn off something else to provide the heaters adequate electricity, and everything that's currently operating is considered essential. Studying the issue, they ruled out turning off one of the still-operating science instruments for a limited time because there's a risk that the instrument would not come back online. After additional study and planning, the engineering team determined they could safely turn off one of the spacecraft's main heaters for up to an hour, freeing up enough power to turn on the thruster heaters. It worked. On Aug. 27, they confirmed that the needed thruster branch was back in action, helping point Voyager 1 toward Earth.

CodeSOD: Switching the Order

The Daily WTF - Thu, 2024-09-12 08:30

Let's say you had 6 different labels to display. There are many, many ways to solve this problem. Most of them are fine. Some of them are the dreaded loop-switch anti-pattern.

Julien unfortunately inherited one of those.

for($i=0;$i<=5;$i++) { switch($i) { case 1 : print('<p>Activé</p>'); break; case 0 : print('<p>Désactivé</p>'); break; case 2 : print('<p>En cours d\'inscription</p>'); break; case 3 : print('<p>En cours de désinscription</p>'); break; case 4 : print('<p>Désinscrit</p>'); break; case 5 : default : print('<p>Marqué invalide</p>'); break; } }

Indentation in the original.

What's beautiful in this, is that we can see that the order of the fields changed. Originally, it was meant to be "Activé", then "Désactivé". But for whatever reason, that wasn't what needed to be on the page, so they flipped the order… by changing the values in the case statement.

It's that bit there that really made this code special, to me. The out-of-order case is the annoying choice that makes bad code truly awful.
