Both small children and cats have a certain tendency to make loud noises at inopportune times, but what if there were a way to combine these auditory effects? This seems to have been the reasoning behind the creation of the Meowsic keyboard, a children’s keyboard that renders notes as cats’ meows. [Steve Gilissen], an appreciator of unusual electronic instruments, discovered that while there had been projects that turned the Meowsic keyboard into a MIDI output device, no one had yet added MIDI input to it, which of course spurred the creation of his Meowsic MIDI adapter.

The switches in the keys of the original keyboard form a matrix of rows and columns, so that creating a connection between a particular row and column plays a certain note. [Steve]’s plan was to have a microcontroller read MIDI input, then connect the appropriate row and column to play the desired note. The first step was to use a small length of wire to connect rows and columns, thus manually mapping connections to notes. After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

[Steve] was farsighted enough to expect some mistakes in the PCB, so he checked the connections before powering the board. This revealed a few problems, which some bodge wires corrected. It still didn’t play during testing, and after a long debugging session, he realized that two pins on an optoisolator were reversed. After fixing this, it finally worked, and he was able to create the following video.

Most of the MIDI hacks we’ve seen involved creating MIDI outputs, including one based on a Sega Genesis. We have seen MIDI input added to a Game Boy, though.

In 1989 a computer scientist argued that more functionality in software actually lowers usability and practicality — leading to the counterintuitive proposition that "worse is better". But is that still true? Python's original creator Guido van Rossum addressed the question last month in a lightning talk at the annual Python Language Summit 2025. Guido started by recounting earlier periods of Python development from 35 years ago, where he used UNIX "almost exclusively" and thus "Python was greatly influenced by UNIX's 'worse is better' philosophy"... "The fact that [Python] wasn't perfect encouraged many people to start contributing. All of the code was straightforward, there were no thoughts of optimization... These early contributors also now had a stake in the language; [Python] was also their baby"... Guido contrasted early development to how Python is developed now: "features that take years to produce from teams of software developers paid by big tech companies. The static type system requires an academic-level understanding of esoteric type system features." And this isn't just Python the language, "third-party projects like numpy are maintained by folks who are paid full-time to do so.... Now we have a huge community, but very few people, relatively speaking, are contributing meaningfully." Guido asked whether the expectation for Python contributors going forward would be that "you had to write a perfect PEP or create a perfect prototype that can be turned into production-ready code?" Guido pined for the "old days" where feature development could skip performance or feature-completion to get something into the hands of the community to "start kicking the tires". "Do we have to abandon 'worse is better' as a philosophy and try to make everything as perfect as possible?" Guido thought doing so "would be a shame", but that he "wasn't sure how to change it", acknowledging that core developers wouldn't want to create features and then break users with future releases. Guido referenced David Hewitt's PyO3 talk about Rust and Python, and that development "was using worse is better," where there is a core feature set that works, and plenty of work to be done and open questions. "That sounds a lot more fun than working on core CPython", Guido paused, "...not that I'd ever personally learn Rust. Maybe I should give it a try after," which garnered laughter from core developers. "Maybe we should do more of that: allowing contributors in the community to have a stake and care".

Here's a lesson for today's colleges from the Associated Press. Online classes + AI = financial aid fraud. "In some cases, professors discover almost no one in their class is real..." Fake college enrollments have been surging as crime rings deploy "ghost students" — chatbots that join online classrooms and stay just long enough to collect a financial aid check... Students get locked out of the classes they need to graduate as bots push courses over their enrollment limits. And victims of identity theft who discover loans fraudulently taken out in their names must go through months of calling colleges, the Federal Student Aid office and loan servicers to try to get the debt erased. [Last week], the U.S. Education Department introduced a temporary rule requiring students to show colleges a government-issued ID to prove their identity... "The rate of fraud through stolen identities has reached a level that imperils the federal student aid program," the department said in its guidance to colleges. An Associated Press analysis of fraud reports obtained through a public records request shows California colleges in 2024 reported 1.2 million fraudulent applications, which resulted in 223,000 suspected fake enrollments. Other states are affected by the same problem, but with 116 community colleges, California is a particularly large target. Criminals stole at least $11.1 million in federal, state and local financial aid from California community colleges last year that could not be recovered, according to the reports... Scammers frequently use AI chatbots to carry out the fraud, targeting courses that are online and allow students to watch lectures and complete coursework on their own time... Criminal cases around the country offer a glimpse of the schemes' pervasiveness. In the past year, investigators indicted a man accused of leading a Texas fraud ring that used stolen identities to pursue $1.5 million in student aid. Another person in Texas pleaded guilty to using the names of prison inmates to apply for over $650,000 in student aid at colleges across the South and Southwest. And a person in New York recently pleaded guilty to a $450,000 student aid scam that lasted a decade. Fortune found one community college that "wound up dropping more than 10,000 enrollments representing thousands of students who were not really students," according to the school's president. The scope of the ghost-student plague is staggering. Jordan Burris, vice president at identity-verification firm Socure and former chief of staff in the White House's Office of the Federal Chief Information Officer, told Fortune more than half the students registering for classes at some schools have been found to be illegitimate. Among Socure's client base, between 20% to 60% of student applicants are ghosts... At one college, more than 400 different financial-aid applications could be tracked back to a handful of recycled phone numbers. "It was a digital poltergeist effectively haunting the school's enrollment system," said Burris. The scheme has also proved incredibly lucrative. According to a Department of Education advisory, about $90 million in aid was doled out to ineligible students, the DOE analysis revealed, and some $30 million was traced to dead people whose identities were used to enroll in classes. The issue has become so dire that the DOE announced this month it had found nearly 150,000 suspect identities in federal student-aid forms and is now requiring higher-ed institutions to validate the identities of first-time applicants for Free Application for Federal Student Aid (FAFSA) forms... Maurice Simpkins, president and cofounder of AMSimpkins, says he has identified international fraud rings operating out of Japan, Vietnam, Bangladesh, Pakistan, and Nairobi that have repeatedly targeted U.S. colleges... In the past 18 months, schools blocked thousands of bot applicants because they originated from the same mailing address; had hundreds of similar emails with a single-digit difference, or had phone numbers and email addresses that were created moments before applying for registration. Fortune shares this story from the higher education VP at IT consulting firm Voyatek. "One of the professors was so excited their class was full, never before being 100% occupied, and thought they might need to open a second section. When we worked with them as the first week of class was ongoing, we found out they were not real people."

We’ve all been there. [Kasyan TV] had a universal adapter for a used laptop, and though it worked for a long time, it finally failed. Can it be fixed? Of course, it can, but it is up to you if it is worth it or not. You can find [Kasyan’s] teardown and repair in the video below.

Inside the unit, there were a surprising number of components crammed into a small area. The brick also had power factor correction. The first step, of course, was to map out the actual circuit topology.

The unit contains quite a bit of heat sinking. [Kasyan] noted that the capacitors in place were possibly operated very near their operating limit. Since the power supply burned, there was an obvious place to start looking for problems.

One of the two synchronous rectifier FETs was a dead short. Everything else seemed to be good. The original FETs were not available, but better ones were put in their place. A snubber diode, though, appeared to be the root cause of the failure. Testing with a programmable load showed the repair to be a success.

Of course, you aren’t likely to have this exact failure, but the detailed analysis of what the circuit is doing might help you troubleshoot your own power supply one day.

We were surprised none of the traces burned out, but that can be fixed, too. Oddly, this cheap supply looked to be better than some of the inexpensive bench supplies we’ve seen. Go figure.

Will an expansion of biofuels increase greenhouse gas emissions, despite their purported climate benefits? That's the claim of a new report from the World Resources Institute, which has been critical of US biofuel policy in the past. Ars Technica has republished an article from the nonprofit, non-partisan news organization Inside Climate News, which investigates the claim. Drawing from 100 academic studies on biofuel impacts, the Institute's new report "concludes that [U.S.] ethanol policy has been largely a failure and ought to be reconsidered, especially as the world needs more land to produce food to meet growing demand." "Multiple studies show that U.S. biofuel policies have reshaped crop production, displacing food crops and driving up emissions from land conversion, tillage, and fertilizer use," said the report's lead author, Haley Leslie-Bole. "Corn-based ethanol, in particular, has contributed to nutrient runoff, degraded water quality and harmed wildlife habitat. As climate pressures grow, increasing irrigation and refining for first-gen biofuels could deepen water scarcity in already drought-prone parts of the Midwest...." It may, in fact, produce more greenhouse gases than the fossil fuels it was intended to replace. Recent research says that biofuel refiners also emit significant amounts of carcinogenic and dangerous substances, including hexane and formaldehyde, in greater amounts than petroleum refineries. The new report points to research saying that increased production of biofuels from corn and soy could actually raise greenhouse gas emissions, largely from carbon emissions linked to clearing land in other countries to compensate for the use of land in the Midwest. On top of that, corn is an especially fertilizer-hungry crop requiring large amounts of nitrogen-based fertilizer, which releases huge amounts of nitrous oxide when it interacts with the soil. American farming is, by far, the largest source of domestic nitrous oxide emissions already — about 50 percent. If biofuel policies lead to expanded production, emissions of this enormously powerful greenhouse gas will likely increase, too.

"People are replacing Google search with artificial intelligence tools like ChatGPT," reports the Washington Post. But that's just the first change, according to a New York-based start-up devoted to watching for content-scraping AI companies with a free analytics product and "ensuring that these intelligent agents pay for the content they consume." Their data from 266 web sites (half run by national or local news organizations) found that "traffic from retrieval bots grew 49% in the first quarter of 2025 from the fourth quarter of 2024," the Post reports. A spokesperson for OpenAI said that referral traffic to publishers from ChatGPT searches may be lower in quantity but that it reflects a stronger user intent compared with casual web browsing. To capitalize on this shift, websites will need to reorient themselves to AI visitors rather than human ones [said TollBit CEO/co-founder Toshit Panigrahi]. But he also acknowledged that squeezing payment for content when AI companies argue that scraping online data is fair use will be an uphill climb, especially as leading players make their newest AI visitors even harder to identify.... In the past eight months, as chatbots have evolved to incorporate features like web search and "reasoning" to answer more complex queries, traffic for retrieval bots has skyrocketed. It grew 2.5 times as fast as traffic for bots that scrape data for training between the fourth quarter of 2024 and the first quarter of 2025, according to TollBit's report. Panigrahi said TollBit's data may underestimate the magnitude of this change because it doesn't reflect bots that AI companies send out on behalf of AI "agents" that can complete tasks on a user's behalf, like ordering takeout from DoorDash. The start-up's findings also add a dimension to mounting evidence that the modern internet — optimized for Google search results and social media algorithms — will have to be restructured as the popularity of AI answers grows. "To think of it as, 'Well, I'm optimizing my search for humans' is missing out on a big opportunity," he said. Installing TollBit's analytics platform is free for news publishers, and the company has more than 2,000 clients, many of which are struggling with these seismic changes, according to data in the report. Although news publishers and other websites can implement blockers to prevent various AI bots from scraping their content, TollBit found that more than 26 million AI scrapes bypassed those blockers in March alone. Some AI companies claim bots for AI agents don't need to follow bot instructions because they are acting on behalf of a user. The Post also got this comment from the chief operating officer for the media company Time, which successfully negotiated content licensing deals with OpenAI and Perplexity. "The vast majority of the AI bots out there absolutely are not sourcing the content through any kind of paid mechanism... There is a very, very long way to go."

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, easy-to-implement circuit.

Most multimeters have a diode test function that can be used to check LEDs; however, this goes a step further. Not only will the probe light up an LED, it will light up no matter which side of the LED the leads are touching. A  Red/Green LED on the probe will indicate if the probe tip is on the anode or cathode.

The probe is powered by a single CR2032 battery, and you may notice there’s no on/off switch. That’s because the probe enters a very low-current sleep mode between uses. The testing intelligence is handled by either an ATtiny85 or, in the newest version, an ATtiny202, though the basic concept and design are compatible with several other chips. All the design files for the PCB, the ATtiny code, a parts list, and a detailed explanation of how it works are available on [David]’s site, so be sure to check them out. Once you build one of these probes, you’ll want something to test it on, so explore some of the LED projects we’ve featured in the past.

Rocky Linux 10 "Red Quartz" has reached general availability, notes a new article in The Register — surveying the differences between "RHELatives" — the major alternatives to Red Hat Enterprise Linux: The Rocky 10 release notes describe what's new, such as support for RISC-V computers. Balancing that, this version only supports the Raspberry Pi 4 and 5 series; it drops Rocky 9.x's support for the older Pi 3 and Pi Zero models... RHEL 10 itself, and Rocky with it, now require x86-64-v3, meaning Intel "Haswell" generation kit from about 2013 onward. Uniquely among the RHELatives, AlmaLinux offers a separate build of version 10 for x86-64-v2 as well, meaning Intel "Nehalem" and later — chips from roughly 2008 onward. AlmaLinux has a history of still supporting hardware that's been dropped from RHEL and Rocky, which it's been doing since AlmaLinux 9.4. Now that includes CPUs. In comparison, the system requirements for Rocky Linux 10 are the same as for RHEL 10. The release notes say.... "The most significant change in Rocky Linux 10 is the removal of support for x86-64-v2 architectures. AMD and Intel 64-bit architectures for x86-64-v3 are now required." A significant element of the advertising around RHEL 10 involves how it has an AI assistant. This is called Red Hat Enterprise Linux Lightspeed, and you can use it right from a shell prompt, as the documentation describes... It's much easier than searching man pages, especially if you don't know what to look for... [N]either AlmaLinux 10 nor Rocky Linux 10 includes the option of a helper bot. No big surprise there... [Rocky Linux] is sticking closest to upstream, thanks to a clever loophole to obtain source RPMs. Its hardware requirements also closely parallel RHEL 10, and CIQ is working on certifications, compliance, and special editions. Meanwhile, AlmaLinux is maintaining support for older hardware and CPUs, which will widen its appeal, and working with partners to ensure reboot-free updates and patching, rather than CIQ's keep-it-in-house approach. All are valid, and all three still look and work almost identically... except for the LLM bot assistant.

Linux 6.15 mistakenly shipped with a nasty power regression for some systems, such as those relying on the "nosmt" option to disable Simultaneous Multi-Threading / Hyper Threading. That idle power regression was fixed for Linux 6.15.2 and Linux 6.16 Git by reverting the troubled patch that introduced the regression. Now merged ahead of Linux 6.16-rc2 is a proper fix for that problematic patch so it could be re-merged without the power fallout...

Recently the Browser Company (the startup behind the Arc web browser) switched over to building a new AI-powered browser — and its beta has just been released, reports TechCrunch, "though you'll need an invite to try it out." The Chromium-based browser has a URL/search bar that also "acts as the interface for its in-built AI chatbot" which can "search the web for you, summarize files that you upload, and automatically switch between chat and search functions." The Browser Company's CEO Josh Miller has of late acknowledged how people have been using AI tools for all sorts of tasks, and Dia is a reflection of that. By giving users an AI interface within the browser itself, where a majority of work is done these days, the company is hoping to slide into the user flow and give people an easy way to use AI, cutting out the need to visit the sites for tools like ChatGPT, Perplexity, and Claude... Users can also ask questions about all the tabs they have open, and the bot can even write up a draft based on the contents of those tabs. To set your preferences, all you have to do is talk to the chatbot to customize its tone of voice, style of writing, and settings for coding. Via an opt-in feature called History, you can allow the browser to use seven days of your browsing history as context to answer queries. The Browser Company will give all existing Arc members access to the beta immediately, according to the article, "and existing Dia users will be able to send invites to other users." The article points out that Google is also adding AI-powered features to Chrome...

In a world first, a research team used 2D materials — only an atom thick — to develop a computer. The team (led by researchers at Pennsylvania State University) says it's a major step toward thinner, faster and more energy-efficient electronics. From the University's announcement: They created a complementary metal-oxide semiconductor (CMOS) computer — technology at the heart of nearly every modern electronic device — without relying on silicon. Instead, they used two different 2D materials to develop both types of transistors needed to control the electric current flow in CMOS computers: molybdenum disulfide for n-type transistors and tungsten diselenide for p-type transistors... "[A]s silicon devices shrink, their performance begins to degrade," [said lead researcher/engineering professor Saptarshi Das]. "Two-dimensional materials, by contrast, maintain their exceptional electronic properties at atomic thickness, offering a promising path forward...." The team used metal-organic chemical vapor deposition (MOCVD) — a fabrication process that involves vaporizing ingredients, forcing a chemical reaction and depositing the products onto a substrate — to grow large sheets of molybdenum disulfide and tungsten diselenide and fabricate over 1,000 of each type of transistor. By carefully tuning the device fabrication and post-processing steps, they were able to adjust the threshold voltages of both n- and p-type transistors, enabling the construction of fully functional CMOS logic circuits. "Our 2D CMOS computer operates at low-supply voltages with minimal power consumption and can perform simple logic operations at frequencies up to 25 kilohertz," said first author Subir Ghosh, a doctoral student pursuing a degree in engineering science and mechanics under Das's mentorship. Ghosh noted that the operating frequency is low compared to conventional silicon CMOS circuits, but their computer — known as a one instruction set computer — can still perform simple logic operations.

Recently, [Samuel Leeuwenburg] got his paws on a Francis! Francis! X1 (yes, that’s the name) espresso machine. This is the espresso machine that is mostly famous for having been in a lot of big TV shows in the 1990s. In the early 2000s, the X1 even became a pretty good espresso machine after the manufacturer did some more tinkering with it, including changing the boiler material, upgrading the pump, etc.

In the case of the second-hand, but rarely used, machine that [Samuel] got, the machine still looked pretty good, but its performance was pretty abysmal. After popping the machine open the boiler turned out to be pretty much full of scale. Rather than just cleaning it, the boiler was upgraded to a brass version for better heat retention and other perks.

More after the break…

The best part of this relatively simple machine is probably that it has been reverse-engineered, making modding it very easy. After some thinking, [Samuel] decided to pull the very basic controller PCB and replace it with something capable of tighter temperature control. This turned into a custom PCB featuring the obligatory Raspberry Pi Pico along with a MAX3185 for water temperature measurement. The Pico had to be programmed to handle heater control duty.  There’s even an HTTP API on the WiFi-enabled Pico board.

Unfortunately, the all-metal enclosure also makes for a perfect Faraday cage, putting an end to remote automation dreams for now, at least. With the machine buttoned up, [Samuel] remembered that the primary task of an espresso machine is to make espresso, which it is now, fortunately, even more capable of than before the surgery, and which requires you to be present at the machine anyway.

Thanks to [Milo] for the tip.

An anonymous reader shared this report from CNET: By using a software emulator to run Atari's 1979 game Video Chess, Citrix engineer Robert Caruso said he was able to set up a match between ChatGPT and the 46-year-old game. The matchup did not go well for ChatGPT. "ChatGPT confused rooks for bishops, missed pawn forks and repeatedly lost track of where pieces were — first blaming the Atari icons as too abstract, then faring no better even after switching to standard chess notations," Caruso wrote in a LinkedIn post. "It made enough blunders to get laughed out of a 3rd-grade chess club," Caruso said. "ChatGPT got absolutely wrecked at the beginner level." "Caruso wrote that the 90-minute match continued badly and that the AI chatbot repeatedly requested that the match start over..." CNET reports. "A representative for OpenAI did not immediately return a request for comment."

Earlier this week looters who stole iPhones "got an unexpected message from Apple," reports the Economic Times. "Please return to Apple Tower Theatre. This device has been disabled and is being tracked. Local authorities will be alerted." Stolen phones "were remotely locked and triggered alarms, effectively turning the devices into high-tech bait. Videos circulating online show the phones flashing the message while blaring loudly, making them impossible to ignore." According to LAPD Officer Chris Miller, at least three suspects were apprehended in connection to the Apple Store burglary. One woman was arrested on the spot, while two others were detained for looting.

Last week Anthropic CEO Dario Amodei said AI could eliminate half the entry-level white-collar jobs within five years. CNN called the remarks "part of the AI hype machine." Asked about the prediction this week at a Paris tech conference, NVIDIA CEO Jensen Huang acknowledged AI may impact some employees, but "dismissed" Amodei's claim, according to Fortune. "Everybody's jobs will be changed. Some jobs will be obsolete, but many jobs are going to be created ... Whenever companies are more productive, they hire more people." And he also said he "pretty much" disagreed "with almost everything" Anthropic's CEO says. "One, he believes that AI is so scary that only they should do it," Huang said of Amodei at a press briefing at Viva Technology in Paris. "Two, [he believes] that AI is so expensive, nobody else should do it ... And three, AI is so incredibly powerful that everyone will lose their jobs, which explains why they should be the only company building it. I think AI is a very important technology; we should build it and advance it safely and responsibly," Huang continued. "If you want things to be done safely and responsibly, you do it in the open ... Don't do it in a dark room and tell me it's safe." An Anthropic spokesperson told Fortune in a statement: "Dario has never claimed that 'only Anthropic' can build safe and powerful AI. As the public record will show, Dario has advocated for a national transparency standard for AI developers (including Anthropic) so the public and policymakers are aware of the models' capabilities and risks and can prepare accordingly. NVIDIA's CEO also touted their hybrid quantum-classical platformCUDA-Q and claimed quantum computing is hitting an "inflection point" and within a few years could start solving real-world problems

Sasha Levin just sent out an initial "request for comments" patch series for the Linux kernel in aiming to establish a Kernel API Specification Framework...

The intersection between “woodworkers” and “programmers” is not a densely populated part of the Venn diagram, but [Michael Schiebler] is there with his Kerf Bend Wizard to help us make wood twist and bend like magic.

Kerf bending is a fine technique we have covered before: by cutting away material on the inside face of a piece of wood, you create an area weak enough to allow for bending. The question becomes: how much wood do I remove? And where? That’s where Kerf Bend Wizard comes to the rescue.

More after the break…

You feed it a spline– either manually or via DXF–and it feeds you a cut pattern that will satisfy that spline: just enough wood removed in just the right places that the edges of the cut should touch when the bend is achieved. This means less cut time and a stronger piece than eyeballing the kerfs. It works with both a table saw blade or a tapered end mill on a CNC or manual router. You can specify the kerf width of your table saw, or angle of your end mill, along with your desired cut depth.

The output is DXF, convenient for use with a CNC, and a simple table giving distances from the edge of the piece and which side to cut, which is probably easier for use on the table saw. (Kerf Bend Wizard is happy to handle complex bends that require kerfing both sides of the material, as you can see.)

This was [Michael]’s thesis project, for which he hopefully got a good grade. The code is “semi-open” according to [Michael]; there’s a GitHub where you can grab an offline version for your own use, but no open-source license is on offer. Being a broke student and an artist to boot, [Michael] also can’t promise he will be able to keep the web version available without ads or some kind of monetization, so enjoy it while you can!

If CNCs or table saws aren’t your thing, kerf bending has long been used with laser cutters, too.

Our thanks (which, as always, is worth its weight in gold) to [Michael] for the tip. If you’re in the intersection of the Venn diagram with [Michael], we’d love to hear what you’re up to.

An anonymous reader quotes a report from the Wall Street Journal: Since 2022, the U.S. has tightened the noose around the sale of high-end AI chips and other technology to China overnational-security concerns. Yet Chinese companies have made advances using workarounds. In some cases, Chinese AI developers have been able to substitute domestic chips for the American ones. Another workaround is to smuggle AI hardware into China through third countries. But people in the industry say that has become more difficult in recent months, in part because of U.S. pressure. That is pushing Chinese companies to try a further option: bringing their data outside China so they can use American AI chips in places such as Southeast Asia and the Middle East (source paywalled; alternative source). The maneuvers are testing the limits of U.S. restrictions. "This was something we were consistently concerned about," said Thea Kendler, who was in charge of export controls at the Commerce Department in the Biden administration, referring to Chinese companies remotely accessing advanced American AI chips. Layers of intermediaries typically separate the Chinese users of American AI chips from the U.S. companies -- led by Nvidia -- that make them. That leaves it opaque whether anyone is violating U.S. rules or guidance. [...] At the Chinese AI developer, the Malaysia game plans take months of preparation, say people involved in them. Engineers decided it would be fastest to fly physical hard drives with data into the country, since transferring huge volumes of data over the internet could take months. Before traveling, the company's engineers in China spent more than eight weeks optimizing the data sets and adjusting the AI training program, knowing it would be hard to make major tweaks once the data was out of the country. The Chinese engineers had turned to the same Malaysian data center last July, working through a Singaporean subsidiary. As Nvidia and its vendors began to conduct stricter audits on the end users of AI chips, the Chinese company was asked by the Malaysian data center late last year to work through a Malaysian entity, which the companies thought might trigger less scrutiny. The Chinese company registered an entity in Kuala Lumpur, Malaysia's capital, listing three Malaysian citizens as directors and an offshore holding company as its parent, according to a corporate registry document. To avoid raising suspicions at Malaysian customs, the Chinese engineers packed their hard drives into four different suitcases. Last year, they traveled with the hard drives bundled into one piece of luggage. They returned to China recently with the results -- several hundred gigabytes of data, including model parameters that guide the AI system's output. The procedure, while cumbersome, avoided having to bring hardware such as chips or servers into China. That is getting more difficult because authorities in Southeast Asia are cracking down on transshipments through the region into China.

The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels.

But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenhouse gas emissions, despite their purported climate benefits.

Today's monkey torture videos are the products of a digitally connected world. People who enjoy watching baby animals probed, snipped, and mutilated in horrible ways often have difficulty finding local collaborators, but online communities like "million tears"—now thankfully shuttered—can help them forge connections.

Once they do meet other like-minded souls, communication takes place through chat apps like Telegram and Signal, often using encryption.

Money is pooled through various phone apps, then sent to videographers in countries where wages are low and monkeys are plentiful. (The cases I have seen usually involve Indonesia; read my feature from last year to learn more about how these groups work.)

For those of us who have worked on SNES and GameCube controllers, we know that these are pretty simple to get into and maintain. However, in the trend of making modern game controllers more complex and less maintainable, Nintendo’s new Switch 2 Pro controller is giving modern Xbox and PlayStation controllers a run for their money in terms of repair complexity. As shown in a teardown by [VK] on YouTube (starting at nine minutes in), the first step is a disappointing removal of the glued-on front plate. After that you are dealing with thin plastic, the typical flimsy ribbon cables and a lot of screws.

The main controller IC on the primary PCB is an ARM-based MediaTek MT3689BCA Bluetooth SoC, which is also used in the Switch 2’s Joy-Cons. The 3.87V, 1070 mAh Li-ion battery is connected to the PCB with a connector, but getting to it during a battery replacement might be a bit of a chore.

The analog sticks are Alps-branded and do not seem to match any other sticks currently on the market. These are (disappointingly) also still resistive potentiometer sticks, meaning they might have to be replaced before long due to stick drift. Reassembly has a few tricky parts, especially with the two sticks being not identical, yet easy to swap by accident. Which would require a second disassembly round.

There’s also a soft-touch coating on these controllers, which have been known to get… gunky after a few years, so time will tell what the lifespan is here. As is typical, these controllers also only work with the Switch and not with a PC or other consoles. Overall, it seems like a nice, silent controller, but the repairability seems low at best.

While KDE Plasma 6.4 is set for release next week, there are already exciting feature improvements brewing for Plasma 6.5...

alternative_right shares a report from Phys.Org: A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere. The goal of the experiment is to gain insight into distant cosmic events by analyzing signals that reach the Earth. Rather than reflecting off the ice, the signals -- a form of radio waves -- appeared to be coming from below the horizon, an orientation that cannot be explained by the current understanding of particle physics and may hint at new types of particles or interactions previously unknown to science, the team said. The researchers published their results in the journal Physical Review Letters. "The radio waves that we detected were at really steep angles, like 30 degrees below the surface of the ice," said Stephanie Wissel, associate professor of physics, astronomy and astrophysics who worked on the ANITA team searching for signals from elusive particles called neutrinos. She explained that by their calculations, the anomalous signal had to pass through and interact with thousands of kilometers of rock before reaching the detector, which should have left the radio signal undetectable because it would have been absorbed into the rock. "It's an interesting problem because we still don't actually have an explanation for what those anomalies are, but what we do know is that they're most likely not representing neutrinos," Wissel said.

Most of us spend our lives within reach of a device that provides a clock, stopwatch, and a timer – you’re almost certainly reading this article on such a device – but there are fewer options if you want a screen-free clock. [Michael Suguitan]’s TOKIDOKI rectifies this situation by combining those three functions into a single, physical, analog clock face.

More after the break…

TOKIDOKI displays time by lighting the appropriate segments of two concentric rings of colored LEDs (Adafruit Neopixel rings); the inner ring indicates hours, while the outer ring displays minutes. There is one clock hand, and while it does indicate the passage of time in some situations, its main function is as a dial to control the clock’s different functions. The hand is connected to a Dynamixel XL-330 servo motor, which also serves as a position sensor. Winding the dial clockwise starts a countdown timer, with each successive full rotation switching to a larger unit of time (a fun/unsettling feature is that the largest chronometric unit is the user’s expected lifetime: 84 years). Winding counterclockwise either starts a stopwatch or sets an alarm, depending on how many full rotations you make.

A Raspberry Pi Pico running some MicroPython firmware manages the device and gets the current time from a local network. To soften the light’s quality, the LED rings are pointed backwards to provide back-lighting off of a recessed surface. The entire device is powered by USB-C, and is enclosed in a 3D-printed housing.

This project was designed as an experiment in minimal interfaces, and it certainly achieved that goal, though we imagine that it takes a bit of time to get used to using this clock. We always enjoy seeing innovative clocks here, from digital to analogue, and those that split the difference.

NASA and Axiom Space have indefinitely delayed the Axiom-4 launch to the International Space Station due to concerns about a persistent air leak in the Russian PrK vestibule of the aging Zvezda module. "The PrK serves as a passageway between the station's Zvezda module and spacecraft docked at its aft port," notes CBS News. From the report: In a blog post, NASA said cosmonauts aboard the station "recently performed inspections of the pressurized module's interior surfaces, sealed some additional areas of interest, and measured the current leak rate. Following this effort, the segment now is holding pressure." The post went on to say the Axiom-4 delay will provide "additional time for NASA and (the Russian space agency) Roscosmos to evaluate the situation and determine whether any additional troubleshooting is necessary." Launched in July 2000 atop a Russian Proton rocket, Zvezda was the third module to join the growing space station, providing a command center for Russian cosmonauts, crew quarters, the aft docking port and two additional ports now occupied by airlock and research modules. The leakage was first noticed in 2019, and has been openly discussed ever since by NASA during periodic reviews and space station news briefings. The leak rate has varied, but has stayed in the neighborhood of around 1-to-2 pounds per day. "The station is not young," astronaut Mike Barratt said last November during a post flight news conference. "It's been up there for quite a while, and you expect some wear and tear, and we're seeing that in the form of some cracks that have formed." The Russians have made a variety of attempts to patch a suspect crack and other possible sources of leakage, but air has continued to escape into space. In November, Bob Cabana, a former astronaut and NASA manager who chaired the agency's ISS Advisory Committee, said U.S. and Russian engineers "don't have a common understanding of what the likely root cause is, or the severity of the consequences of these leaks." "The Russian position is that the most probable cause of the PrK cracks is high cyclic fatigue caused by micro vibrations," Cabana said. "NASA believes the PrK cracks are likely multi-causal including pressure and mechanical stress, residual stress, material properties and environmental exposures. "The Russians believe that continued operations are safe, but they can't prove to our satisfaction that they are, and the US believes that it's not safe, but we can't prove that to the Russian satisfaction that that's the case." As an interim step, the hatch leading to the PrK and the station's aft docking compartment is closed during daily operations and only opened when the Russians need to unload a visiting Progress cargo ship. And as an added precaution on NASA's part, whenever the hatch to the PrK and docking compartment is open, a hatch between the Russian and U.S. segments of the station is closed. "We've taken a very conservative approach to close a hatch between the US side and the Russian side during those time periods," Barratt said. "It's not a comfortable thing, but it is the best agreement between all the smart people on both sides. And it's something that we crew live with and enact." Cabana said last year that the Russians do not believe "catastrophic disintegration of the PrK is realistic (but) NASA has expressed concerns about the structural integrity of the PrK and the possibility of a catastrophic failure."

The city of London is no stranger to tall constructions today, but long before the first skyscrapers would loom above its streets, Watkin’s Tower was supposed to be the tallest structure in not only London but also the entirety of the UK. Inspired by France’s recently opened Eiffel tower, railway entrepreneur and Member of Parliament [Sir Edward Watkin] wanted to erect a structure that would rival the Eiffel tower, as part of a new attraction park to be constructed near the Middlesex hamlet of Wembley. In a retrospective, [Rob’s London] channel takes a look at what came to be known as Watkin’s Folly among other flattering names.

After [Gustave Eiffel], the architect of the Eiffel tower recused himself, a design competition was held for a tower design, with the Illustrated Catalogue of the 68 designs submitted available for our perusal. The winner turned out to be #37, an eight-legged, 366 meter tall tower, much taller than the 312.2 meter tall Eiffel tower, along with multiple observation decks and various luxuries to be enjoyed by visitors to Wembley Park.

Naturally, [Watkin] commissioned a redesign to make it cheaper, which halved the number of legs, causing caused subsidence of the soil and other grievances later on. Before construction could finish, the responsible company went bankrupt and the one constructed section was demolished by 1907. Despite this, Wembley Park was a success and remains so to this day with Wembley Stadium built where Watkin’s Folly once stood.

An anonymous reader quotes a report from Ars Technica: Do you remember the Pirelli Cyber Tire? No, it's not an angular nightmare clad in stainless steel. Rather, it's a sensor-equipped tire that can inform the car it's fitted to what's happening, both with the tire itself and the road it's passing over. The technology has slowly been making its way into the real world, starting with rarified stuff like the McLaren Artura. Now, Pirelli is going to put some Cyber Tires to work for everybody, not just supercar drivers, in a new pilot program with the regional government of Apulia in Italy. The Cyber Tire has a sensor to monitor temperature and pressure, using Bluetooth Low Energy to communicate with the car. The electronics are able to withstand more than 3,500 G as part of life on the road, and a 0.3-oz (10 g) battery keeps everything running for the life of the tire. The idea was to develop a better tire pressure monitoring system, one that could tell the car exactly what kind of tire -- summer, winter, all-season, and so on -- was fitted, and even its state of wear, allowing the car to adapt its settings appropriately. But other applications suggested themselves -- at a recent CES, Pirelli showed how a Cyber Tire could warn other road users about aquaplaning. Then again, we've been waiting more than a decade for vehicle-to-vehicle communication to make a difference in daily driving to no avail. Apulia's program does not rely on crowdsourcing data from Cyber Tires fitted to private vehicles. Regardless of the privacy implications, the rubber isn't nearly in widespread enough use for there to be a sufficient population of Cyber Tire-shod cars in the region. Instead, Pirelli will fit the tires to a fleet of vehicles supplied by the fleet management and rental company Ayvens. Driving around, the sensors in the tires will be able to infer how rough or irregular the asphalt is, via some clever algorithms. That's only one part of it, however. Pirelli and Apulia are also combining input from the tires with data from a network of road cameras and some technology from the Swedish startup Univrses. As you might expect, this data is combined in the cloud, and dashboards are available to enable end users to explore the data.
