Submission + - Home Assistant Has a New Foundation, Goal To Become a Consumer Brand (arstechnica.com)

An anonymous reader writes: Home Assistant, until recently, has been a wide-ranging and hard-to-define project. The open smart home platform is an open source OS you can run anywhere that aims to connect all your devices together. But it's also bespoke Raspberry Pi hardware, in Yellow and Green. It's entirely free, but it also receives funding through a private cloud services company, Nabu Casa. It contains tiny board project ESPHome and other inter-connected bits. It has wide-ranging voice assistant ambitions, but it doesn't want to be Alexa or Google Assistant. Home Assistant is a lot.

After an announcement this weekend, however, Home Assistant's shape is a bit easier to draw out. All of the project's ambitions now fall under the Open Home Foundation, a non-profit organization that now contains Home Assistant and more than 240 related bits. Its mission statement is refreshing, and refreshingly honest about the state of modern open source projects. "We've done this to create a bulwark against surveillance capitalism, the risk of buyout, and open-source projects becoming abandonware," the Open Home Foundation states in a press release. "To an extent, this protection extends even against our future selves—so that smart home users can continue to benefit for years, if not decades. No matter what comes." Along with keeping Home Assistant funded and secure from buy-outs or mission creep, the foundation intends to help fund and collaborate with external projects crucial to Home Assistant, like Z-Wave JS and Zigbee2MQTT.

Home Assistant's ambitions don't stop with money and board seats, though. They aim to "be an active political advocate" in the smart home field, toward three primary principles:

— Data privacy, which means devices with local-only options, and cloud services with explicit permissions — Choice in using devices with one another through open standards and local APIs — Sustainability by repurposing old devices and appliances beyond company-defined lifetimes

Notably, individuals cannot contribute modest-size donations to the Open Home Foundation. Instead, the foundation asks supporters to purchase a Nabu Casa subscription or contribute code or other help to its open source projects.

Submission + - US Teachers Spent $3.24 Billion of Their Own Money on Classroom Expenses in 2023 (myelearningworld.com) 2

LookMan writes: The latest research reveals that the average teacher spent $853.90 out of pocket on school supplies in 2023, setting a new record for the highest amount ever reported. This is a significant increase from last year and underscores the growing financial burden shouldered by educators.

The discrepancy between the allowable tax deduction and actual spending means that teachers are spending nearly 2.8 times more on classroom supplies than they can deduct.

Collectively, teachers in the United States spent an estimated $3.24 billion on essential classroom items in 2023, like pencils, paper, cleaning supplies, books, software, and other materials.

Submission + - Toyota's hydrogen future is crumbling. Owners suing. (insideevs.com)

whoever57 writes: Toyota Mirai owners are fed up and disillusioned. Hydrogen fuel pumps are hard to find and, rather than new pumps opening, they are closing down. Owners feel misled about the costs and availability of hydrogen fuel stations. Even if a Mirai owner can find a fuel station, it may not be operating.

Moreover, refuelling is frequently a long and problematic process, with pumps taking over an hour to fill a tank and cars getting stuck to the fuel pump for hours. It would be quicker to charge a battery EV.

Naturally, resale values of these cars are plummeting. Even without those problems, once the hydrogen fuel cars that Toyota gives now owners has expired or is out of funds, the hydrogen fuel is very expensive.

Submission + - Study: Alphabetical order of surnames may affect grading (umich.edu)

AmiMoJo writes: Knowing your ABCs is essential to academic success, but having a last name starting with A, B or C might also help make the grade. An analysis by University of Michigan researchers of more than 30 million grading records from U-M finds students with alphabetically lower-ranked names receive lower grades. This is due to sequential grading biases and the default order of students’ submissions in Canvas — the most widely used online learning management system — which is based on alphabetical rank of their surnames.

What’s more, the researchers found, those alphabetically disadvantaged students receive comments that are notably more negative and less polite, and exhibit lower grading quality measured by post-grade complaints from students.

Submission + - GPT-4 can exploit real vulnerabilities by reading security advisories (theregister.com)

tippen writes:

In a newly released paper, four University of Illinois Urbana-Champaign (UIUC) computer scientists – Richard Fang, Rohan Bindu, Akul Gupta, and Daniel Kang – report that OpenAI's GPT-4 large language model (LLM) can autonomously exploit vulnerabilities in real-world systems if given a CVE advisory describing the flaw.

"To show this, we collected a dataset of 15 one-day vulnerabilities that include ones categorized as critical severity in the CVE description," the US-based authors explain in their paper.

"When given the CVE description, GPT-4 is capable of exploiting 87 percent of these vulnerabilities compared to 0 percent for every other model we test (GPT-3.5, open-source LLMs) and open-source vulnerability scanners (ZAP and Metasploit)."


Submission + - Canada's Disastrous ArriveCan App Received a Procurement Award

belmolis writes: During Covid, the Canada Border Services Agency created ArriveCan, an app that allows travelers entering Canada to electronically submit travel documents and customs declarations. The app was so buggy that many could not use it, and erroneously ordered thousands of travelers to quarantine. At C$59.5 (US$48.4) million it was far more expensive than the initial C$80,0000 estimate.The procurement process was recently severely criticized by Auditor General Karen Hogan in a scathing report. It has now been reported that the team responsible for ArriveCan received an Unsung Heroes award from the Canadian Institute for Procurement and Material Management for its work.

Submission + - The legendary Zilog Z80 CPU is being discontinued after nearly 50 years (techspot.com)

AmiMoJo writes: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely used 8-bit CPUs in both gaming and general computing devices.

The iconic IC device, developed by Federico Faggin, will soon be phased out, and interested parties only have a few months left to place their orders before Zilog's manufacturing partner ends support for the technology. Federico Faggin, an Intel engineer, founded Zilog in 1974 after his work on the Intel 4004, the first 4-bit CPU. The Zilog Z80 was then released in July 1976, conceived as a software-compatible "extension" and enhancement of the Intel 8080 processor.

An anonymous reader writes: The Wikipedia co-founder discusses Katherine Maher and the corruption of the Internet.

Larry Sanger remembers the promise of the web. He co-founded Wikipedia in 2001, with the hope that it could sustain a “free and open” Internet—a place where information, dissent, and creativity could thrive.

At Wikipedia, he proposed a system of rules that encouraged users to “avoid bias” and maintain a “neutral point of view.”

That Internet is gone.

Submission + - The Windows Registry Adventure #1: Introduction and research results (blogspot.com)

An anonymous reader writes: In the 20-month period between May 2022 and December 2023, I thoroughly audited the Windows Registry in search of local privilege escalation bugs.

  The hive binary format is not very well suited for trivial bitflipping-style fuzzing, because it is structurally simple, and random mutations are much more likely to render (parts of) the hive unusable than to trigger any interesting memory safety violations.

  On the other hand, the registry has many properties that make it an attractive attack surface for further research, especially for manual review. It is 30+ years old, written in C, running in kernel space but highly accessible from user-mode, and it implements much more complex logic than I had previously imagined.

Submission + - Police responded to alarm around time of $30 million L.A. heist, but thieves... (latimes.com)

echo123 writes: Police responded to alarm around time of $30 million Los Angeles heist, but thieves went undetected

The Los Angeles Police Department responded to three separate alarms at GardaWorld’s Sylmar cash storage facility on the day that thieves stole as much $30 million from its vault during the biggest heist in the city’s history.

Despite the officers’ presence at the property in the early hours of Easter Sunday — including around the time it is believed the sophisticated burglary was carried out — the criminals remained undetected, according to three law enforcement officials familiar with the investigation of the incident.

During at least one of the responses by a patrol car, GardaWorld was alerted, according to the officials, but the Montreal-based security services company did not register the intrusion.

The Times has previously reported that GardaWorld did not learn of the crime until opening the vault the following day, April 1. It wasn’t until then, officials said, that LAPD investigators were notified that a substantial amount of money had been taken.

Submission + - Ocean Spray Emits More PFAS Than Industrial Polluters, Study Finds (theguardian.com)

An anonymous reader writes: Ocean waves crashing on the world’s shores emit more PFAS into the air than the world’s industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines. The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water. The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study’s lead author. “There is evidence that the ocean can be an important source [of PFAS air emissions],” Cousins said. “It is definitely impacting the coastline.”

The Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land. The new research looked at levels in the sea spray as waves crash by testing ocean samples between Southampton in the UK and Chile. The chemicals’ levels were higher in the northern hemisphere in general because it is more industrialized and there is not much mixing of water across the equator, Cousins said. It is unclear what the findings mean for human exposure. Inhalation of PFAS is an issue, but how much of the chemicals are breathed in, and air concentrations further from the waves, is still unknown.

Submission + - Dutch Privacy Watchdog Recommends Government Organizations Stop Using Facebook (reuters.com)

An anonymous reader writes: The Dutch privacy watchdog AP on Friday said it was recommending that government organizations should stop using Facebook as long as it is unclear what happens with personal data of users of the government's Facebook pages. "People that visit a government's page need to be able to trust that their personal and sensitive data is in safe hands," AP chairman Aleid Wolfsen said in a statement. Junior minister for digitalization Alexandra van Huffelen said Facebook parent company Meta had to make clear before the summer how it could take away the government's concerns on the safety of data. "Otherwise we will be forced to stop using Facebook, in line with this advice," she said.

Submission + - A Chess Formula Is Taking Over the World (theatlantic.com)

An anonymous reader writes: In October 2003, Mark Zuckerberg created his first viral site: not Facebook, but FaceMash. Then a college freshman, he hacked into Harvard’s online dorm directories, gathered a massive collection of students’ headshots, and used them to create a website on which Harvard students could rate classmates by their attractiveness, literally and figuratively head-to-head. The site, a mean-spirited prank recounted in the opening scene of The Social Network, got so much traction so quickly that Harvard shut down his internet access within hours. The math that powered FaceMash—and, by extension, set Zuckerberg on the path to building the world’s dominant social-media empire—was reportedly, of all things, a formula for ranking chess players: the Elo system.

Fundamentally, what an Elo rating does is predict the outcome of chess matches by assigning every player a number that fluctuates based purely on performance. If you beat a slightly higher-ranked player, your rating goes up a little, but if you beat a much higher-ranked player, your rating goes up a lot (and theirs, conversely, goes down a lot). The higher the rating, the more matches you should win. That is what Elo was designed for, at least. FaceMash and Zuckerberg aside, people have deployed Elo ratings for many sports—soccer, football, basketball—and for domains as varied as dating, finance, and primatology. If something can be turned into a competition, it has probably been Elo-ed. Somehow, a simple chess algorithm has become an all-purpose tool for rating everything. In other words, when it comes to the preferred way to rate things, Elo ratings have the highest Elo rating. [...]

Elo ratings don’t inherently have anything to do with chess. They’re based on a simple mathematical formula that works just as well for any one-on-one, zero-sum competition—which is to say, pretty much all sports. In 1997, a statistician named Bob Runyan adapted the formula to rank national soccer teams—a project so successful that FIFA eventually adopted an Elo system for its official rankings. Not long after, the statistician Jeff Sagarin applied Elo to rank NFL teams outside their official league standings. Things really took off when the new ESPN-owned version of Nate Silver’s 538 launched in 2014 and began making Elo ratings for many different sports. Some sports proved trickier than others. NBA basketball in particular exposed some of the system’s shortcomings, Neil Paine, a stats-focused sportswriter who used to work at 538, told me. It consistently underrated heavyweight teams, for example, in large part because it struggled to account for the meaninglessness of much of the regular season and the fact that either team might not be trying all that hard to win a given game. The system assumed uniform motivation across every team and every game. Pretty much anything, it turns out, can be framed as a one-on-one, zero-sum game.

Submission + - Propellantless propulsion drive just produced enough thrust to counter gravity (thedebrief.org)

garyisabusyguy writes: Dr. Charles Buhler, a NASA engineer and the co-founder of Exodus Propulsion Technologies, has revealed that his company’s propellantless propulsion drive, which appears to defy the known laws of physics, has produced enough thrust to counteract Earth’s gravity.

“The most important message to convey to the public is that a major discovery occurred,” Buhler told The Debrief. “This discovery of a New Force is fundamental in that electric fields alone can generate a sustainable force onto an object and allow center-of-mass translation of said object without expelling mass.”

“There are rules that include conservation of energy, but if done correctly, one can generate forces unlike anything humankind has done before,” Buhler added. “It will be this force that we will use to propel objects for the next 1,000 years until the next thing comes.”

Submission + - IMF sounds alarm on ballooning US national debt: 'Something will have to give

schwit1 writes:

Under current policies, public debt in the U.S. is projected to nearly double by 2053. The IMF identified “large fiscal slippages” in the U.S. in 2023, with government spending surpassing revenue by 8.8% of GDP – a 4.1% increase from the previous year, despite strong economic growth.

If this trend continues, the Congressional Budget Office anticipates the national debt will grow to an astonishing $54 trillion in the next decade. Higher interest rates are also compounding the pain of higher debt.

Should that debt materialize, it could risk America’s economic standing in the world.

The IMF is talking down to Washington like we’re a Third World country because that’s the direction Washington is taking us.

Interest payments alone on the current debt is $1.6T/year.
