"We need you in the fight," says the American legal expert in privacy, surveillance, AI, and Internet freedom of speech who became the EFF's new executive director in March. As EFF celebrates the anniversary of its founding 1990, "Each headline is different, but they tell one story: Many of the threats that once seemed hypothetical are now reality, and EFF's work to ensure technology supports rights, justice, freedom, and innovation for all people has never been more critical." Governments and large corporations possess surveillance capabilities that were unimaginable just a few years ago. Ever greater concentrations of power are shaping speech, creativity, markets, and democratic institutions. Governments are increasingly seeking to control the internet and people's ability to access information and communicate freely. Our community's work is fundamental to the future of our countries, our livelihoods, and literally our lives... These are perilous times. It is also a moment of extraordinary possibility. The future of AI has not been written and we can work together to get it right. We can make sure our laws reflect the needs of the modern digital age. We can build the technologies that empower rather than marginalize communities. For me, the work starts with recognizing that digital rights are not a siloed policy issue. We must fight and win on the digital terrain to organize, speak freely, access healthcare, find work, receive an education, and participate fully in democracy. We can and must reject a false choice between innovation and civil liberties, and build power across movements to make sure technology truly works for people... EFF's founders understood something remarkably prescient: Technology and civil liberties would become inseparable. Now we all live digital lives, and the important digital rights issues that EFF has worked on since 1990 have become kitchen-table issues all around the world. EFF's founders understood that how technology is built, developed, used, and controlled deeply intersects with rights, justice, freedom, and democracy. EFF's unique combination of world-class lawyers, activists, and public interest technologists pursue change simultaneously in the courts, legislatures, companies, and our communities, and pierce through false choices. This integrated, intersectional approach, grounded in deep legal, policy, and technical expertise, is a linchpin in fighting and winning against some of the most powerful forces in the world — both governments and trillion-dollar companies. We defend people against unlawful government data collection and challenge license plate and face surveillance in our communities. We shape AI law and policy to protect civil liberties and support creativity and innovation. We push companies to strengthen encryption, fight to ensure you have the right to own what you buy, and build public interest technologies like Privacy Badger and Certbot that millions of people rely on every day. This work matters because it all answers the same question: Will technology empower or control us? Major battles the executive director sees on the horizon" "Challenge increasingly sophisticated government and corporate surveillance systems that endanger our rights, democracy, safety and security." "Preserve strong encryption and online anonymity." "Ensure AI is developed and used in ways that respect fundamental rights and works for those who build it, use it, and are affected by it." "Confront the concentrations of power that limit access to new creativity and defend the rights of developers to build and innovate." "To meet these challenges, we must not only utilize the powerful levers of successful litigation, smart policy interventions, and effective public interest technology tools. We must also build a broader movement that recognizes that fights on the digital terrain are integral to all our fights for rights and justice... Together, our EFF community can help broaden the public conversation about technology's role in society and continue building the collective power necessary to shape the future rather than react to it.... "I'm looking forward to meeting more of you at my first EFFecting Change livestream on August 12 with Cory Doctorow, and hope this conversation is just the beginning of finding new ways to work together..." The blog post ends by noting that "We need you and others in the fight. Please renew your membership, become a recurring monthly supporter, and introduce someone new to EFF by snagging them a gift membership. "Everything we accomplish — every lawsuit, every policy victory, every public interest technology tool, every campaign — is possible because people like you are committed to ensuring technology strengthens freedom, privacy, creativity, and opportunity for everyone. "The future we want and need will be built by people and movements working together to ensure technology empowers rather than oppresses. "Let's build that future together."

Meta "said in a court filing on Monday that four states were seeking $1.4 trillion in penalties," reports Reuters, "over accusations the company designed its Facebook and Instagram platforms to addict young users and misled the public about their safety." Meta put forward the figure in its response to the attorneys general's filings on how penalties should be calculated if the states prevailed at trial. The number, which has not previously been disclosed and is close to Meta's market capitalization of around $1.5 trillion, comes ahead of an August trial in Oakland, California, over the claims brought by California, Colorado, Kentucky and New Jersey against the company. Meta said the amount was unsupported by the evidence. "A sanction of that size has no analog in the history of consumer protection enforcement," the company said in the filing. "The plaintiffs' outlandish calculations have no basis in fact or law," the company said in a statement, adding that it would continue to defend itself against the states' demands. A spokesperson for California Attorney General Rob Bonta said in a statement the lawsuit "alleges Meta has prioritized profits over the safety of kids and fueled the mental health crisis we see impacting a generation of American children. The California Department of Justice looks forward to holding Meta fully accountable at trial in August...." Meta has denied the allegations, saying the attorneys general have no evidence it misled consumers about its platforms' alleged addictiveness because "social media addiction" is not an established psychiatric condition, and therefore statements that its platforms were not addictive could not be false... Last month, [U.S. District Judge] Rogers rejected Meta's bid to cancel the trial, saying there remained factual disputes over whether its social media platforms were addictive, whether Meta falsely denied it designed them that way, and whether it "partially" directed the platforms at children. "A further 14 states have brought claims under their own laws, which will be heard at a separate trial in February..." Thanks to Slashdot reader Sparkatron for sharing the article.

"Are you armed?!" the police officer screamed. "Get out of the car!" A writer for the car-news site The Drive describes how "a technological chain linking surveillance cameras, AI, and law enforcement... led to me and my wife being surrounded by police, hands on their guns, in a Kohl's parking lot in suburban Minnesota." After dropping off our Amazon returns, we'd just gotten back in the Range Rover and reversed maybe two feet out of the spot when four cop cars came flying out of nowhere and boxed us in... The Plymouth Police Department had been tracking me for days using Flock license plate cameras, waiting for the right moment to strike, because they thought I'd stolen the Range Rover. And the reason I was ID'd as a dangerous car thief was a simple data error made 2,000 miles away in California, creating an edge case within an edge case that Flock's AI camera network was unable to handle... "The plates on this car are stolen," Officer Ganshyn said... This made absolutely no sense. Car companies keep meticulous track of the fleets they loan out to the media. The vehicles all have special manufacturer or dealer plates that are logged every time one enters or exits... The New Jersey plates that were allegedly stolen from the LA dealer were 34 03 DTM, not 34 10 DTM. But when the police report was created and the plate was entered into Flock's system, it was just recorded as 34 DTM. Just the five large characters, no little number in the middle... Flock's AI tech wasn't registering that non-standard little number when it began picking up the Range Rover around town... I connected the final dot. A lot of vehicles in [Range Rover manufacturer] JLR's media fleet have a New Jersey manufacturer plate with the same alphanumeric structure — 34 ## DTM — and Officer Ganshyn observed that meant it was now a nationwide issue. Anywhere a police department has a partnership with Flock, any other JLR-owned car with the same plate structure is going to get flagged as stolen. In fact, four other 34 ## DTM cars were being tracked around Minnesota that week, according to Officer Ganshyn. I was just the first one to get nabbed. The only way to stop it would be for the LAPD to correct their initial report and update Flock's system, which Jaguar Land Rover was now racing to make happen following the phone call. Still, he warned me to drive straight home, park the Range Rover, and leave it there. If I were to cross into the neighboring town, I'd probably get flagged again and go through this entire ordeal again with a different set of officers. His parting words were ominous: "You're lucky we're in Plymouth. If you were in Minneapolis, they definitely would've come at you with guns drawn." Ironically, even the original license plate wasn't stolen either, the article points out. It was reported misplaced during a Los Angeles photo shoot, and "The corporation had to report the plate as lost to law enforcement," according to the police report — and even then, the plate "was reported as NJ 34DTM instead of NJ 3403DTM." The author's conclusion? "Once these systems have you in their crosshairs, there's pretty much only one way it can go... A simple data-entry error, magnified and broadcast nationwide by a growing surveillance network operated through an opaque partnership between a private company and public agencies, led police to identify me as a car thief and set up a sting to take me down. I mean, they even had a drone flying overhead during the 'bust'... "Thank God our kids weren't with us." Thanks to long-time Slashdot reader sinij for sharing the article.

Debian 13.6 is out today as the newest point release of Debian Trixie to ship the latest security fixes and other maintenance updates...

[Jenny] and I were talking about [Bitluni]’s experiment in scale, where he will take 65,536 cheap microcontrollers, network them all together, and give each one an RGB pixel. From there, antics will surely ensue. Right now, he’s only got 8,192 of them up and running, and already the novel problems and opportunities are rearing their heads.

We all know it from our own hacking. In theory, doing something ten times is ten times doing it once. But then in practice, entirely new phenomena appear as you scale up that were simply not there in the small. Maybe it happens when you repeat it one hundred times, or a thousand.

Viewed positively, this is the property of emergence: how the whole can be more than the sum of its parts, and how biology isn’t just chemistry multiplied by a few million interactions. In our blinky world, a massive wall of LEDs is a display, not just a bunch of pixels.

On the flip side, going from one microcontroller with a 10 mA current draw to 64 Ki controllers, with 655 A, is more than just a difference in scale. You need to learn a new skill set to handle the problem. Making a single prototype is a different problem from making a run of badges for a conference of 5,000 – you’ll need a team, and won’t be able to just hack it alone – not to even mention the parts sourcing woes.

So I loved watching [Bitluni] going through the upscaling. He certainly had an idea of what he was getting himself into, but as with the emerging properties of a big system, there are often emerging problems, and those you can’t always see ahead of time. Have you gotten into a project that scaled itself into something qualitatively different? Tell us about it.

WD 1856 b is the only confirmed case of a planet that survived the death of a Sun-like star. It’s a Jupiter-size world orbiting a white dwarf—the burned-out remnant of a Sun-like star. Now, a team of astronomers has used the James Webb Space Telescope to take a closer look at this planet for the first time, and what they found makes an already strange system even stranger.

A feeding frenzy

WD 1856 b was an accidental discovery. Astronomers pointed the TESS observatory at a sample of roughly 2,000 white dwarfs in 2020. These stars are the remains of a Sun-like star that have already gone through a red-giant phase, leaving behind an Earth-size body that’s primarily composed of elements like carbon and oxygen. The TESS team was searching for small objects like comets or asteroids that might transit across the face of these dead stars.

What they found in the WD 1856 system was a gas giant. “As soon as they looked at it, they said, okay, that’s weird,” said Christopher O’Connor, a theoretical astrophysicist at Cornell University and co-author of the recent Nature study on WD 1856 b.

The federal government is rewriting its rules governing ranching on public lands to increase the number of cattle, sheep, and other livestock grazing on 155 million acres in the West, an area twice the size of New Mexico.

Public lands grazing is overseen by a nearly century-old system that heavily subsidizes some of the wealthiest Americans while doing little to address its harms to the environment, ProPublica and High Country News found last year.

Even though rangeland management experts say overgrazing has degraded public lands, the new rules being drafted by the US Department of the Interior’s Bureau of Land Management—the first overhaul since 1995—would instead expand the practice.

Ceramic 3D printers, despite using the same fundamental mechanism as standard FDM printers, are much harder to find. Part of this comes down to the material properties of fired ceramics versus thermoplastics, but they’re also significantly harder to build; for example, in his ceramic printer build, [Joshua Bird] had to deal with severe material shrinkage, collapsing bridges, and the surprisingly abrasive effects of clay.

The centerpiece of the printer is the clay extruder: an air compressor pushes clay along a tube into the extruder, which uses an auger to squeeze the clay through the nozzle, while a gap at the top lets trapped air escape. The extruder has enough control for successful retractions, but rheology remained a challenge: the clay needed to be soft enough to flow through the nozzle, but stiff enough to form bridges without collapsing. [Joshua] thus pressurized the clay as much as possible, making it possible to use stiffer clay mixtures. The extruder’s greatest challenge was longevity: [Joshua] tried many 3D-printed plastic augers, but the clay abraded them all much too quickly, often in under an hour of use; a 3D-printed stainless steel extruder solved this.

Printing in ceramic isn’t a simple process: for each part, [Joshua] had to mix the clay, load it into the tube, clean the extruder, actually print the object, let it dry, fire it, apply glaze, and fire it again. The clay’s shrinkage during drying and firing destroyed many prints, but [Joshua] was nevertheless able to print a double-walled cup, a decorative climbing-themed cup, and even a chain-mail mesh.

The 3D printer’s motion system is a polar design, an adaptation of his earlier non-planar 3D printer, which might eventually make it easier to print overhangs. We’ve previously seen a similar auger-based clay extruder, an approach reminiscent of direct-granule FDM printing.

The FCC has approved (PDF) Reflect Orbital's Earendil-1 test satellite, which will use a 60-by-60-foot mirror to reflect sunlight back to Earth after dark. "The reflected light from the satellite is supposed to span an area about 3 miles wide on the ground," reports PCMag. It comes despite objections from astronomers and environmental groups who are concerned that the satellites will unleash intrusive light pollution. From the report: The approval is only for one satellite, dubbed Earendil-1, which is meant to test Reflect Orbital's technology for shining sunlight back to Earth. The satellite will boast a steerable thin-film reflector measuring about 60 feet by 60 feet, with the goal of powering solar farms at night or illuminating disaster-struck areas after dark to help rescue teams. Reflect Orbital envisions operating over 50,000 satellites by 2035, effectively surrounding the Earth with a fleet of mirrors. The proposal has faced stiff pushback from environmental groups and astronomers who are concerned that the satellites will unleash intrusive light pollution. The opposition has been so strong that the FCC received over 1,800 public comments on the application, many of them objecting to Reflect Orbital's plan for Earendil-1. [...] [T]he FCC approved the satellite, noting the grant is only "for a single demonstration satellite" to test an innovative technology that could advance American leadership in space. "The Communications Act states that it is the policy of the United States to 'encourage the provision of new technologies and services to the public,' and Reflect Orbital's demonstration satellite is an example of a potentially groundbreaking technology that the Commission has found is in the public interest to support," the order says. But on the most controversial aspect of the satellite, the FCC said the concerns around Reflect Orbital's solar reflector are "unrelated to the Commission's role in authorizing use of radiofrequency spectrum, and even if the Commission had authority to review and condition these operations (which it does not), these harms are unlikely to occur. In addition, the commission said that U.S. courts have blocked the FCC from using "a generalized public interest requirement beyond its statutory authority in regulating communications. Accordingly, the operations of a solar reflector in space would not be reviewed as part of the Bureau's public interest analysis." The regulator also noted that conducting an environmental review for the satellite went beyond its authority. Even if the FCC did have the power, the commission emphasized that the grant is for a single satellite, not 50,000. "The majority of these comments focus on a hypothetical plan to deploy tens of thousands of satellites, and those who argue the single satellite will harm the human environment do not demonstrate with specificity the potential harm will be caused by the single satellite, but rather rely on the same studies as the commenters objecting to a larger constellation," the FCC adds.

Ceefax was the BBC’s broadcast teletext service that ran until 2012, providing text and rudimentary graphics that were broadcast invisibly with the TV signal. In order to get this teletext data merged into the analog TV signal, special equipment was needed, of which [Nathan Dane] has a 1997-era unit on his bench to take a gander at.

Interestingly, until this time the Ceefax signal had been generated centrally in London, meaning that regional TV broadcasts might have Ceefax issues on occasion due to retransmission glitches. This makes this Ceefax Inserter  system so much more interesting, as it was one of the early examples of what these regional stations would end up installing in their racks.

At their core these units are regular PCs, running MS-DOS 6.22 on a 486-class CPU and all the typical bits and bobs that go with a PC. The speculation here is that these are essentially rebranded industrial PCs, which would make a lot of sense. As for how [Nathan] got his hands on these units, it required a deal with the company scrapping them, preventing him from showing details of the software configuration.

Following a booting demonstration, we get the teardown of a typical 1990s rackmount PC, revealing a rather interesting backplane with the mainboard being one of the cards on it. Of these, two ISA cards provide the special Ceefax sauce as well as a timing signal in the form of a PDC card featuring a Lattice CPLD or FPGA that VCRs could use to automatically start recording.

The Ceefax main event comes in the form of the inSERT Teletext Encoder card. This is pretty much its own computer system, featuring a TI TMS34010 CPU and its own RAM as well as IO. Compared to modern takes on teletext generators, this card appears to directly mix the analog signals, without any kind of conversion.

Although teletext systems have been largely shutdown now at this point due to the transition to digital TV broadcasting, there’s still a lot to be said for having such a service available for basic news and information.

China successfully recovered an orbital rocket booster for the first time, landing the Long March 10B's first stage into a net-equipped sea platform after its maiden launch. "This mission marks my country's first successful controlled recovery of a launch vehicle and the world's first network-based recovery of a launch vehicle," the China Aerospace Science and Technology Corporation (CASC) announced via social media shortly after the launch. (Translation by Google.) "It signifies a historic breakthrough for my country in the field of reusable rocket technology and will lay a solid foundation for accelerating the improvement of my country's space access capabilities." Space.com reports: The Long March 10B is a two-stage rocket that stands about 207 feet (63 meters) tall, according to the state-owned CASC, the main contractor for China's space program. The vehicle's first stage burns kerosene and liquid oxygen (LOX) propellants, whereas the second stage uses LOX and liquid methane. In reusable mode, the Long March 10B can loft about 16 tons of payload to low Earth orbit. And the rocket flew with a payload on its debut liftoff -- a satellite that successfully reached "its predetermined orbit," according to the CASC update. That post did not provide any details about the spacecraft or its orbit. It did give a brief rundown of the first-stage recovery, however. "Approximately 6 minutes after the first and second stages separated, the first stage returned vertically and was successfully recovered at a sea-based recovery platform using a net system," CASC officials wrote, noting that launch occurred from the Hainan Commercial Space Launch Site on Friday at 12:15 a.m. EDT (0415 GMT; 12:15 p.m. Beijing time.) "The launch and first-stage recovery missions were a complete success."

After previously fixing an overly bright picture from a Voodoo graphics card with a simple resistor on one of the RAMDAC’s pins to correct its faulty internal Vref, [Bits und Bolts] got called out for not taking component drift into account. Thus in an update video he shows how instead to use an adjustable AMS1117 voltage regulator to hopefully prevent either the original issue or something new and exciting from cropping up later.

The basic idea here is to use the external voltage reference (Vref) pin for this ICS5342 RAMDAC and supply it with a constant 1.235V. If unused – as on this Orchid-branded Voodoo card – it is connected via an 0.1 microFarad capacitor to ground. This fortunately means that the pin is routed to easily accessible pads that make this modification relatively straightforward.

Basically this is where the AMS1117-ADJ chip comes into the picture, as a widely available adjustable LDO option, even if the 0.8A current rating is very much overkill for this application. With the supplied voltage the lowest voltage this LDO can output is around 1.25V, which is within the 1.10 – 1.35 V range of the datasheet.

Of course, with the PCB never having had a provision for this part, much of the rest of the video is about planning out where to place and route the components. After that tedious work and testing that nothing explodes, the new voltage is used for the RAMDAC’s Vref pin, fixing the brightness issue.

While one could argue that this RAMDAC is likely simply defective and already beginning to break down inside, this should at least give it a bit longer on what seems to be a little used card anyway.

An anonymous reader quotes a report from The New York Times: Apple on Friday accused OpenAI of stealing secrets about products still in development, setting up a legal face-off between two of the world's biggest tech companies. In a lawsuit filed in U.S. District Court for the Northern District of California, the consumer tech giant said that OpenAI, a leader in artificial intelligence that has a new hardware business, had asked job candidates from Apple to share details about secret projects and to bring device components and prototypes to their interviews. Apple also accused an OpenAI employee of downloading internal documents from a laptop owned by the iPhone maker. OpenAI used the confidential information to approach Apple's manufacturing partners, including asking one partner to demonstrate Apple's technique for finishing metal on its devices, the lawsuit says. Apple sent a letter to OpenAI in February to raise concerns that confidential information could be "making its way to OpenAI's business improperly," according to the suit. OpenAI did not respond, Apple said. "OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets," Apple wrote in its lawsuit. [...] In its lawsuit Friday, Apple accused Tang Tan, OpenAI's chief hardware officer and a former Apple executive, of coaching his hires from Apple on how to evade Apple's security processes for departing employees. Apple accused another former employee, Chang Liu, of using a former colleague's Apple-owned laptop to access and download technical documents while working at OpenAI. Mr. Liu told that Apple employee what information about unannounced products she should study before job interviews, Apple said. Mr. Liu also planned to access internal documents through an Apple-owned laptop that he didn't return when he left the company, according to the lawsuit. OpenAI had misled the manufacturing company it approached to learn about the metal finishing technique to believe it had Apple's permission to view it, according to the lawsuit. Apple is seeking an injunction that would prevent OpenAI from possessing, using or sharing Apple's trade secrets, as well as an order requiring OpenAI to return Apple's intellectual property.

We’re not exactly sure how old [SnailMail] is, but he’s probably a member of Generation Alpha considering that to our wizened eyes the lad looks only slightly older than a fetus– which makes it all the more impressive that he’s written his own text editor, from scratch, in C– on a 386. See, [SnailMail] tried to learn the modern way, with IDEs that have code completion and AI integration, but his thoughts couldn’t gel in the modern environment. So he went online and bought an old IBM-compatible complete with monochrome amber monitor, and a whole 4MB of RAM. Big spender that he is, [SnailMail] upgraded that to 8MB.

Rather than fall victim to the siren song of Wolfenstien 3D or SimCity, he set out to learn to code: C, specifically, since that language bridges four decades between [SnailMail] and his new PC. Even more specifically, he got ahold of disks for Borland Turbo C and Turbo C++, which brings back memories for some of us. Of course the lad also had to learn how to use a DOS PC at the same time, but a teen in the 80s with a fresh box would have climbed the same steep learning curve. Some of you probably remember doing so yourselves. Just like you–or the hypothetical teen in the 80s–[SnailMail] did it not by googling or begging Claude for answers, but by digging into books. Many books.

After all the reading, he started with a text editor, something we remember being a pretty big project not given to first year students. Video evidence suggests he pulled it off. He describes how his solution works from about 8:00 in the video, so you greybeards in the audience can judge his work for yourself.

If you’re a member of Gen Alpha reading this and looking to learn to program, we cannot recommend this technique highly enough– [SnailMail] is going to have a better understanding of the underlying logic of computer science than a lot of CS grads being frocked today. Especially when you consider he ends by promising to learn assembly, something we heartily endorse.

There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make enough high-quality hardware qubits to connect into the error-corrected logical qubits we need, and how we generate the states needed to perform universal computation on those logical qubits. But there are also many less prominent challenges that will need to be solved before we can perform calculations.

One of those challenges, which only affects some types of hardware, is calibration. For devices we manufacture, like superconducting qubits, there are always subtle variations among individual qubits. (This is not true when we use something like an atom to hold the qubit, but the lasers that control them can drift.) As a result, this hardware is put through a process called calibration, where we test different frequencies and amplitudes of the microwave pulses that control them to find the combination that produces the lowest error rates, and then save those settings for use in calculations.

However, you can't perform the typical calibration process while e you're doing calculations, which means drift becomes an issue for long and complicated algorithms. Google, though, has figured out that it's possible to do calibration using the same data that's used for error correction.

Having a pump in a remote location where you aren’t constantly monitoring it is a common scenario, which can be unfortunate when said pump runs into problems like a dry well, jammed impeller or power issues. This is where pump monitors like the older SymCom (now Littelfuse) PumpSaver Plus 233P will protect the pump if such conditions are detected. Of course, the infrared communication port on it uses an undocumented protocol that was meant to be used with a long-since discontinued handheld device. Ergo [Elizabeth Camporeale] saw fit to reverse-engineer this protocol.

In the installation manual for this device this Informer unit is briefly mentioned along with the information it will display on its screen, making it clear that it’s quite literally just there to act as a display for the information that’s constantly generated on this interface. Naturally, this is incredibly useful if you wish to tie the system into a wider monitoring and automation system.

Somewhat unusual, this IR interface on the used 233P-1.5 unit turned out to be use a 5,000 baud NRZ, MSB-first protocol, with the juicy details fully documented and a Python-based decoder implementation provided.

Naturally [Elizabeth] didn’t just reverse-engineer this for the fun of it, but also for ESPHome integration. This uses a setup as can be seen in the top image, with an ESP32-C6 module providing the processing power and Wi-Fi, with a standard phototransistor recording the data pumped out by the pump monitor.

Longtime Slashdot reader schwit1 shares a report from Inside Higher Ed: For the first time since he started teaching Welfare Economics and Social Choice Theory nearly two decades ago, Brown University economics professor Roberto Serrano gave his students a take-home midterm this spring. Quite a few students had expressed anxiety about being in a classroom after a gunman killed two students and injured nine in a December mass shooting at Brown, and so "it was appropriate," he said, to allow students to take their exams at home. But by the end of the semester, Serrano regretted the decision. Dozens of students in the class likely used artificial intelligence to cheat and earn perfect or near-perfect scores on their midterm, he said. Serrano in turn made the final exam in-person, which led more than a dozen students to drop the course and even more to fail it. Administrators' response to the widespread cheating event has been "meek," he said, and the incident has raised questions about how universities can -- and should -- respond to AI-enabled cheating at scale. "I am not declaring [the midterm] void for now. I am going to give the class a chance to prove me wrong," he wrote. "That is, if the distribution of the final exam is roughly similar to the distribution of the midterm, I will count the midterm. Otherwise, which is of course what I expect to happen, I will declare the midterm void and reweigh the final accordingly." Serrano heard crickets from his students, but 18 of them subsequently dropped the class. Nine students remained enrolled but did not take the final exam. And Serrano said the results proved him right; three students earned a zero, and the average score on the final was 48.6 percent -- by far a historic low, he said. Previously, the average final exam score had never dropped below 65 percent. Only a few students scored similarly to how they did on the midterm.

More cities and towns deployed drones to spot illegal fireworks during the Fourth of July celebrations commemorating America’s 250th anniversary—leading to a $100,000 fine in one instance and coming as part of a broader national trend of first responders turning to drone surveillance.

Police and fire departments have described using both increased drone surveillance and steep fines to deter people from shooting off illegal fireworks, with many departments publicizing their drone videos on social media and warning that their drones will be watching in the future. Incidents involving illegal fireworks have led to costly fires, injuries, and even multiple deaths each year, along with creating local air and noise pollution for residential neighborhoods.

This year, the $100,000 fine for illegal fireworks came from the Sacramento Fire Department in Northern California deploying its own drones for the first time on the Fourth of July, according to CBS News Sacramento. Sacramento Fire Captain Justin Sylvia described the fire department’s drones as being capable of recording scenes in high-resolution video to help investigators identify the house or closest location using Google Maps.

Dutch intelligence agencies say Russian hackers have been hijacking unsecured internet-connected cameras, including likely doorbell and security cameras, to spy on NATO military bases and transport routes used to move weapons to Ukraine. "Organisations with IP [internet protocol] cameras on these routes have now been warned so that they could take action," said the AIVD domestic security and MIVD military intelligence agencies. Targeted NATO member states include the Netherlands and Ukraine. The Telegraph reports: While the intelligence agencies did not specify the type of cameras hacked, the doorbell systems are frequently used by people to monitor their property from mobile phones. Hackers then use readily available apps to scan for devices that might be accessible. The Dutch investigation found that many of the cameras were unsecured, and "often have standard passwords, outdated firmware and standard configurations." They said: "When the IP camera is identified, the malicious party can attempt to access the IP camera via the internet. This is often relatively easy, because many IP cameras connected to the internet are insufficiently secure." [...] The practice is now considered easier and cheaper than using drones and satellites to gather intelligence. It also aids operational surprise because most camera owners are blissfully unaware their devices have been penetrated by hackers. Ground-based cameras offer a unique perspective on the terrain, which isn't the case with conventional aerial-based spy kit.

China's sprawling state-owned rocket developer, maker of the country's Long March rocket family, announced it recovered a reusable orbital-class booster for the first time Friday in the South China Sea.

The milestone mission began with the liftoff of a Long March 10B rocket from the Wenchang Commercial Space Launch Site on Hainan Island, China's southernmost province. Powered by seven kerosene-fueled engines, the approximately 209-foot-tall (63.6-meter) rocket took off at 12:15 am EDT (04:15 UTC), or 12:15 pm local time at the seaside spaceport at Wenchang.

About 10 minutes later, the Long March 10B booster descended from space and guided itself into a four-legged frame affixed to an offshore vessel. Tensioned cables stretched over the ship in a grid pattern captured the rocket as it shut down its landing engines, leaving the smoldering booster hanging in midair. The rocket's upper stage continued into orbit and deployed a payload known only as CX-26. Chinese officials hailed the flight as a "complete success."

NHTSA is ordering autonomous vehicle developers to explain by the end of the month how they will stop driverless cars from interfering with police, firefighters, and paramedics. TechCrunch reports: [NHTSA Administrator Jonathan Morrison] noted in the letter (PDF) that the agency has "identified a clear pattern of driverless AVs interfering with law enforcement and other first responders," citing instances in which these vehicles drove into active emergency scenes, blocked the paths of ambulances and firefighters, or failed to recognize and respond to basic safety conditions like flashing lights, flares, smoke, fire, and traffic cones. The agency has demanded that AV developers present their "solutions" to this problem by the end of the month. "Let me be clear: the inability to detect and appropriately respond to such situations represents a functional insufficiency," Morrison's letter reads. "Emergency scenes are not rare or extreme 'edge cases.' As such, NHTSA is today issuing a call to action for AV developers and operators to immediately focus their resources on fixing this issue." The agency doesn't explicitly call out any particular company in the letter; however, the details suggest it is directed at robotaxi operators like Waymo. [...] The agency's letter to AV developers doesn't say what the consequences would be if the request is ignored. Nor does it outline what the acceptable solutions would be. But the agency does imply it would hold companies accountable, just as it does human drivers who impede law enforcement. "Every second matters when law enforcement officers, firefighters, or paramedics are answering a call because lives are on the line," the letter states. "That is why human drivers who impede these operations are subject to fines and even jail time." The agency also noted in a press release accompanying the letter that it's making progress on updating Federal Motor Vehicle Safety Standards (FMVSS) requirements, which govern vehicle design and equipment requirements. These proposed changes could help autonomous vehicle companies like Tesla and Zoox, which are developing vehicles without steering wheels, pedals, or other features required on human-driven cars. The agency has already proposed rules that would eliminate the need for windshield wipers, sun visors, defogging systems, and tire placards. The agency released a new 2026 Regulatory Plan and Unified Agenda last week, outlining its proposals.

If you’re not aware, there is such a thing as adorable little three digit LCD 7-segment displays. They come in a ten-pin DIP package and are just begging to be integrated into a project. The catch is they are just a tiny bit weird. Luckily for us all, [Nagy Krisztián] spells out exactly how to use them.

The first odd thing about these ten-pin LCD displays have a footprint that doesn’t quite mesh with standard 0.1 inch spacing, meaning they will not cleanly fit into a breadboard. Luckily, one can solve this with a bit of force. It’s a small part, and the pins don’t seem to mind.

The second odd thing is wrapping one’s head around the pin mapping. Figuring out which pins activate which segments in the digits is easier if one keeps in mind that each segment of each digit is the product of two different pins. For example, “2A” is digit two, segment A, and is the product of pins 3 and COM4.

That’s not all. Electrically speaking, driving this LCD isn’t nearly as straightforward as an LED.

With an LED display, the COM pins are either common anode or common cathode, which tells one whether lighting up a segment means holding the COM pin at GND with voltage applied to the segment pin, or the other way around. But in the case of this LCD display, the polarity applied is swapped every cycle. Oh, and inactive COM pins need to held at half-voltage. Neat!

[Nagy] drives the whole thing with little more than an ATtiny84 microcontroller and a few resistors. A switchable half-voltage signal is cleverly created by combining a simple voltage divider and taking advantage of the fact that the ATtiny84’s pins can be in one of three different states depending on how they are configured: high, low, or high-impedance (pin configured as an input). Each COM pin on the display gets connected to both an ATtiny84 pin, and to the supply voltage via two resistors forming a voltage divider. When the ATtiny drives the pin high, the LCD pin sees about 3 V. When the pin is driven LOW, the LCD pin sees 0 V. When the ATtiny configures the pin as an input, the LCD pin receives about 1.5 V.

The bulk of the software is defining which pins and states equal which digits, and cycling the LCD at a rate of vaguely 60 Hz which delivers flicker-free results.

We appreciate the clever combination of voltage divider with pin configuration to create three switchable voltage levels. If you liked that and want to see more serious leveraging of pin configuration on a microcontroller, check out how to drive seven LEDs with only two pins.

On October 1st, New York City will become the first U.S. city to ban deceptive subscription practices, requiring companies to offer simple cancellation options or face fines of $525 per user subscription, back fees, and additional penalties. The Mamdani administration is also proposing a junk-fee rule requiring sellers, landlords, hotels, and other businesses to "advertise the total price for any good or service, including all mandatory additional charges and fees, up front." The Guardian reports: "People shouldn't have to wait on hold for half an hour or send a certified letter or show up to a store in person in order to cancel" a subscription, said Samuel AA Levine, the city's commissioner of consumer and worker protection, in an interview. The new measures are expected to be announced in a press conference on Friday morning. The proposed fee rule could have an especially wide impact, sending ripples through New York's expensive housing market, where about 70% of residents rent. Apartment renters in the US face a rising tide of add-on fees such as "boiler management" and "lifestyle" charges from management companies, which make true rental costs hundreds of dollars higher than the price stated on real-estate company websites. If the proposed renters rule passes after public comment and hearing, any mandatory fees, including annual ones, would need to be included in the stated monthly rental price, Levine said. The current situation creates "a scenario where rather than competing on price, companies are competing on their ability to hide the true price. That's the worst kind of incentive" -- and one that deeply distorts the market, Levine said.

Back in 2024, we reported on the discovery of the Quest shipwreck, the polar exploration vessel that served Arctic explorer Sir Ernest Shackleton on his last voyage. Shackleton died before reaching their destination, and the ship sank in 1962. The Royal Canadian Geographic Society (RCGS) has now released the first images of the wreck more than 60 years after it sank, published in Canadian Geographic magazine.

Shackleton, of course, is most famous for his ill-fated voyage on the Endurance, which became trapped in sea ice in 1914 and sank. Shackleton and his crew defied the odds and survived. (The Endurance shipwreck was finally found in 2022.) By the time Shackleton returned to England, the country was embroiled in World War I, and many of his men enlisted. Shackleton was considered too old for active service. He was also deeply in debt from the Endurance expedition, earning a living on the lecture circuit. But he still dreamed of making another expedition to the Arctic Ocean north of Alaska to explore the Beaufort Sea. He got funding from an old school chum, John Quillier Rowett.

Shackleton purchased a wooden Norwegian whaler, Foca I, which his wife Emily renamed Quest. When the Canadian government withdrew its support, the mission shifted back to the Antarctic, and the Quest received an extensive retrofit. The improvements included a new deckhouse, a heated crow’s nest, a wireless set, and an odograph for tracing and charting the route automatically, as well as a Lucas deep-sea sounding machine, a large and pricey collection of cameras and photographic equipment, and even a small airplane.

A former ransomware negotiator was sentenced to 70 months in prison yesterday after colluding with BlackCat scammers to extort the victims he was hired to protect.

As a ransomware negotiator for the company DigitalMint, Florida resident Angelo Martino's job was "to negotiate with cybercriminals to mitigate the ransoms paid by [DigitalMint's] clients," the US government said in a sentencing memorandum on Tuesday. "Instead, Martino provided the cybercriminals with confidential negotiation information to maximize the ransoms in exchange for a portion of the ransom payments. Five of the victims whom Martino was supposed to help paid over $75 million to ransomware affiliates, including likely millions of dollars in ransom demands inflated as a result of the confidential information provided by Martino."

Martino, 41, pleaded guilty and asked for a 24-month sentence, noting that he "provided substantial assistance that contributed to the indictment and conviction of two co-defendants." As described in this November 2025 article, the co-defendants were Texas resident Kevin Martin, a ransomware negotiator for DigitalMint, and Georgia resident Ryan Goldberg, an incident manager at security firm Sygnia.

With no new data or clear reasoning, a panel of advisors hand-selected by anti-vaccine Health Secretary Robert F. Kennedy Jr. voted last September to strip federal recommendations for a combination shot against measles, mumps, rubella, and varicella (chickenpox). An analysis published today by independent researchers does the work the advisors neglected to do before the vote and, in turn, shows how harmful the decision is to vulnerable US toddlers.

The decision last fall followed clumsy discussion by Kennedy's dubiously qualified advisors, who make up the Advisory Committee on Immunization Practices (ACIP) for the Centers for Disease Control and Prevention. Most noticeably, their unprompted review of the MMRV vaccine did not include a standard decision-making framework ACIP has historically used to comprehensively evaluate what the change would mean for US children in practice—including basic questions, such as which children would be affected.

Still, the decision meant that private health insurance providers would no longer be required to cover the vaccine, called MMRV. It also meant the shot would no longer be available through a federal program that provides vaccines to about half of American children, mostly from low-income families.

An anonymous reader quotes a report from Ars Technica: The European Union is ramping up pressure on Meta to make big changes to Facebook and Instagram after the European Commission preliminarily found that features like autoplay, infinite scroll, and highly personalized content recommendations were addictive. On Thursday, the EC said its investigation indicated that "Meta did not adequately assess the risks of its addictive design on the physical and mental wellbeing of users, including minors and vulnerable adults." "These features fuel the user's urge to keep scrolling and shift the brain into 'autopilot mode,' contributing to unhealthy habits and compulsive use," the commission said. Over the next few months, Meta will have an opportunity to dispute the claims, and it has already taken a defensive stance. Meta's spokesperson, Ben Walters, told Reuters that Meta disagrees with the commission's preliminary findings, which supposedly "don't accurately take into account the significant steps we've taken to protect teens." "Since this investigation began, we rolled out Teen Accounts that automatically protect teens and put parents in control -- allowing them to block access to Instagram at night and cap daily screen time at just 15 minutes," Walters said. However, the EC emphasized that Meta's current mitigation efforts, including time management tools activated by default for teens, "failed to effectively tackle the risks stemming from its addictive design." Additionally, parental controls were deemed "only effective if parents and guardians possess adequate technical expertise" and dedicated "effort and time to understand them effectively." "This undermines the efficiency of such measures in addressing the inherent risks posed by Instagram and Facebook's addictive design," the EC said, particularly for minors. At this stage, the EC recommended that Meta consider "disabling key addictive features such as 'autoplay' and 'infinite scroll' by default, implementing effective 'screen time breaks,' and adapting its recommender system to make it less engagement-oriented." If Meta fails to make changes to comply with the EU's Digital Services Act, the company risks fines up to 6 percent of its global annual turnover when the EC makes its final decision in the coming months. "Our starting point is that, based on our findings, this design is too addictive and changes need to be made," Henna Virkkunen, the EU's tech chief, told Reuters. "The next step is either that Meta changes its design or a non-compliance decision will follow," she said, noting in the press release that the EU's priority is "protecting the physical and mental health of Europeans." "The Digital Services Act provides a clear framework to hold platforms accountable for the addictive design and effects of their services," Virkkunen said. "We are fully committed to enforcing our legislation in Europe." The report also notes that the EC will share findings from experts on Monday that "could help pave the way for a Europe-wide social media ban for teenagers." It's not looking much better for Meta in the U.S., either. The company faces a lawsuit from 29 states that claim Meta's platforms addict kids. "That trial begins in August, and states may seek up to $1.4 trillion in penalties if Meta is found guilty," reports Ars.

You’ve doubtlessly seen the current crop of robot dogs and, if you are like us, thought about getting one to play with. The problem is that the cheap ones are toys, and the serious ones cost serious money. But now you can experiment with a mid-range cost one for free in your browser. The sponsor will be happy to sell you a robot in kit or assembled form, although it is the OpenCat robot (we’ve covered it before), so you could simply build a real one yourself if you wanted to.

The code is all in a Web-based IDE, and the main file is deceptively simple. However, the real work is in read_serial (in the src/moduleManager.h file, for some reason) and reaction in the aptly-named src/reaction.h file. If you just want to play, you can use the buttons in the simulator or enter serial commands (documented elsewhere). For example, ksit will make the dog sit down.

You can change as much code as you like. You might consider starting simple and just sending commands programmatically, but you can dive as deep as you like. Press compile up at the top right, and it will load and run your code in the virtual robot. If you run it off the desk (of course, we did), you can reset and try again.

Here’s a quick example to get you started:

//***********************
#define BITTLE // Petoi 9 DOF robot dog: 1 on head + 8 on leg

#define BiBoard_V1_0
//***********************

#include "src/OpenCat.h"

void setup() {
Serial.begin(115200); // USB serial
Serial.setTimeout(SERIAL_TIMEOUT);

while (Serial.available() && Serial.read())
; // empty buffer

Serial.println("Hello Hackaday!");
initRobot();
}

unsigned int loopct=0;
unsigned int phase=0;

#define cmdtokenEOF 0xFFFF

// commands (token + argument)
char *cmd[] =
{
"sit", // good boy
"up", // stand up
"bf", // back flip
"ff", // forward flip
"EOF" // string doesn't matter here
};

unsigned int cmdtoken[] = {
T_SKILL,
T_SKILL,
T_SKILL,
T_SKILL,
cmdtokenEOF
};

#define LOOPDELAY 1000 // number of loops between actions

void loop() {
// This code runs repeatedly
// Put any change here if you want to change behaviors
if (loopct % 1000 == 0 )
{
loopct=0;
if (cmdtoken[phase]==cmdtokenEOF) phase=0;
strcpy(newCmd,cmd[phase]);
token=cmdtoken[phase++];
newCmdIdx=1;
}
loopct++;

reaction();
}

The robot is better than the cheap toys, but it still lacks many sensors. You can add on a few simple sensors that appear to mount in the dog’s mouth, or you can replace its head with an arm if you opt for beefy enough servos.

Of course, we’ve seen plenty of robot dogs. We want one, but we don’t know what we’d do with it. Any ideas?

Disney is exploring a free tier for Disney+ that would make some content available without a subscription. According to Nielsen data, the three largest free streamers accounted for 18.7% of watch time on U.S. TVs in April, up from 16.8% a year earlier and 12.7% in April 2024. Business Insider reports: Product and tech chief Adam Smith spoke about enabling free-tier content during a streaming town hall on Thursday afternoon, one staffer said. Smith didn't share a timeline for this initiative or a sense of the scope, this person added. A person familiar with Disney's streaming strategy said these talks are part of an ongoing discussion about concepts to better serve fans. Currently, the Disney+ and Hulu bundle costs $12.99 a month with ads or $19.99 without ads at full price.
