It's an icon of early internet videos: 12 badgers doing calisthenics while a mushroom and snake occasionally appear on screen, known as "Badger Badger Badger" or "The Badger Song."
"Charlie Bit My Finger" -- a private family video which unexpectedly became one of the earliest global viral videos on YouTube -- has been officially preserved by the British Film Institute (BFI).
Your Google account likely stores a lot of important information, from your home address in Google Maps and your work emails in Gmail, to family pictures in Google Photos and personal conversations in Google Chat. You don’t want anyone else gaining access to that data—and nor does Google.
To minimize the chances of anyone else accessing your account, Google has created a Security Checkup tool that you can use in any web browser. It takes you quickly and simply through a security audit, warning you about potential issues without overloading you with settings and menu screens.
If you’re logged into Google in your web browser, you can get to the Security Checkup tool from this page. Alternatively, you can find it from your Google account page, by clicking Security and sign-in (the Checkup should appear at the top).
The Security Checkup will alert you to pressing problems that have been identified, but you can work through each section in turn, whether or not there are related issues. To start, you can see the devices that you’re currently signed into Google on under Your devices. It will also list their location, operating system, and when you last used them.
If there’s anything you don’t recognize here, or there’s a device you no longer have, you can disconnect it from your account remotely. It’s best to err on the side of caution here—if you accidentally disconnect a device that is actually genuine and that you are still using, the worst that’s going to happen is you’ll need to sign in again on that device.
Then we’ve got the Sign-in and recovery section. This contains crucial information about how your account is accessed, so make sure everything here is in order, and up to date. For example, you might be asked to confirm your backup email address and phone number, which will be crucial (and trusted) communication channels for Google to use should you somehow get signed out of your account.
Many devices now use passkeys, where you use something like a PIN code or a fingerprint scan to access your accounts. You can also see a list of passkeys you’ve set up here—and again, as with the list of devices, passkeys can be revoked if you see something that might be a problem (such as an authorization you don’t recognize).
Then you have the Your saved passwords section. If you’re using Android and Google Chrome to save login credentials to your Google account, then the stored passwords will appear here. Google will warn you if any passwords have been repeated or aren’t strong enough (usually because they’re not long or complex enough).
The Safe Browsing section of the Security Checkup is specifically for users of the Chrome browser, and gives you extra, proactive protection against dangerous websites and extensions. However, it also requires a greater level of data sharing with Google (so it can check your activity), and can feel restrictive for those who feel confident recognizing threats themselves—so the choice is yours.
Open Recent security activity, and you see a detailed list of all security-related activity on your Google account across the last 28 days. This will include activity such as devices you’ve signed in on, or deleted data you’ve recovered (something a hacker could potentially attempt to do). If anything here looks suspicious, you can alert Google.
Under Your third-party connections, you can see apps, sites, and services that have some kind of connection to Google. Maybe you use your Google credentials to log into them, for example, or they’re utilities that you use to manage your Google Photos account. Google-made smart home devices may also appear here.
The rules are the same as they are with connected devices: If you see anything that shouldn’t be there, you can break the link. The app or site in question will no longer have access to your Google account and its data. If you need to use it again, you’ll need to reapprove the connection. It’s a good idea to regularly review this list, to make sure older services that you no longer regularly use have been removed.
The final part of the Google Security Checkup is Gmail Settings, and from here you can view and make changes to email accounts you’ve blocked, and email accounts you’ve connected to. If you see anything that’s not right, you’re able to make changes. And with that done, your security checkup is complete—and your Google account should be significantly more secure than it was before.

In September 2021, The Wall Street Journal published the Facebook Files, a series of reports based on internal documents from the tech company that, among other things, showed its executives were aware of the harms Instagram and Facebook were causing young people. It was a bombshell. It triggered the biggest reputational crisis for Mark Zuckerberg’s company, which weeks later rebranded as Meta. The person behind it was engineer Frances Haugen, 42, who left her post at Facebook carrying 21,000 internal documents. The U.S. Senate summoned her to testify, and investigations were opened into her revelations.

Renewable energy is the cornerstone of any sustainable society, but why limit your options to wind or solar installations? In the United States alone, over one million homes host a tiny, furry alternative power source without even realizing it. As a young YouTuber known as Flamethrower recently demonstrated, it’s time for hamsters to start pulling their weight around the house. Or, at the least, it’s time for them to start turning hamster wheels into miniature, makeshift turbines.
The idea came to Flamethrower after his brother received one of the tiny pets for his birthday. Although adorable, naturally nocturnal hamsters are often up at all hours of the night running on their little exercise accessories. While laying awake to the sound of a spinning, squeaky wheel, the amateur engineer realized how to make the best of an unexpectedly annoying situation.
“So what did I do? Exploit it for energy production, of course!” he declared in his recent video entry.
Turbines help generate most of the world’s energy, and their underlying principles are simple enough. Electricity funneled through wires to a motor will make it spin, but the reverse is also true—spin a motor, and electricity will generate through its terminals into battery storage. The fundamentals are basically the same whether a turbine spins thanks to steam, wind, or nuclear power. Or hamsters.
However, a hamster-powered turbine is not the easiest project to design. As the YouTuber explained, a 5 volt (V) DC motor hypothetically needs to spin at over 10,000 RPM to simply reach a smartphone’s standard 15 watt charging speed. Even if such a superpowered hamster existed, its speed would likely cause the motor to melt before it provided any juice to a battery—and therein lay another issue.
Batteries don’t only store energy—they are designed to provide electricity at a steady current when needed. However, a standard battery also must receive a higher voltage than it stores in order to amass any reserves.
Part of the solution came from a device known as an energy harvester module, which takes small voltages and amplifies them to an acceptable level for a battery. But the problem is that the amount of required voltage increases in direct proportion to the energy that’s being stored, meaning yet another unfeasible hurdle. The hobbyist ultimately relied on a system called maximum power point tracking (MPPT) to calculate the optimal input and output proportions for the energy harvester and a few other components.
All that potential energy is only as good as the battery that stores it, however. For this project, the YouTuber relied on lithium-ion cells salvaged from a broken electric scooter. Flamethrower hooked up his rig to the hamster wheel’s axis, then gave his brother’s pet the night to get its steps in. The next day, he attached his phone via a USB cable charging port to test the whole thing for the first time.
The initial setup worked flawlessly, although it charged at a snail’s pace. Naturally, he booted up his thermal camera nearby (who doesn’t own one?) to investigate any pain points in the system. It turns out the issue did have anything to do with the hamster wheel charger itself, but his outdated USB cable. After swapping that out with a newer replacement, phone charging sped up dramatically.
“And with that, my hamster’s life finally has a purpose,” the inventor declared.
As absurd as it appears, it’s hard to argue with such an ingenious source of free electricity. Hypothetically, the same idea could be adapted to basically anything in a house that spins mechanically, like a stationary bike. Then again, the whole point is to have the hamster do the work, not you. In any case, the YouTuber seems to be on to something here. The way Flamethrower tells it, the rodent may be more reliable than solar or wind energy.
“It’s supposed to be nocturnal but I’m starting to think it never sleeps,” he said.

TikTok executives decided not to disable notifications during school hours, ignoring recommendations from their own safety team, and paid millions of dollars to parents’ and teachers’ associations to promote the social network in schools. Snapchat sent alerts to teenagers while they were in class urging them to share what was happening in the classroom. Google executives knew that YouTube was recommending videos to students during the school day that were unrelated to their lessons. Meta paid “teen ambassadors” to promote Instagram and hand out gifts to their classmates.

Leftover Altoid tins are staple components in all types of handy, DIY projects. Once you eat the mints, the aluminum containers routinely house basic first aid kits, miniature speakers, sewing accessories, and even watercolor paints. But for the YouTuber Exercising Ingenuity, one specific use came to mind.
“Have you ever looked at a tin of Altoids and thought, ‘That looks like a tiny computer?’” he asked in a video on May 9.
Of course, whether or not you imagined the same endeavor is beside the point—because the creator went ahead and did it. The final result may not be the most versatile pocket computer ever designed, but it definitely is one of the most portable.
Exercising Ingenuity was particularly inspired by cyberdecks, which first rose to prominence among hackers during the 1980s. The term originated in William Gibson’s landmark 1984 science fiction novel Neuromancer, and basically boils down to a rugged standalone laptop (with a little bit of punk flare thrown in for good measure). Most actual cyberdeck projects are built with an emphasis on utility and resilience, but Exercising Ingenuity’s chief goal was to make his variant as small as possible.
The problem wasn’t finding an appropriately tiny CPU and LCD screen—a Raspberry Pi Zero and an old, two-inch display both did the trick. Instead, the more difficult challenge was cramming a mechanical keyboard into the pocket-sized tin. That required learning how to construct a diode matrix configuration typing input, then individually assembling and soldering each key on his keyboard. Although the time-lapse video makes the job look incredibly frustrating and hard on the fingers, the YouTuber swears it was a “really enjoyable part of the project.” To each their own.
From there, it was a matter of designing a flexible 3D-printed interior frame and cramming everything into the tin. This was easier said than done, and required the hobbyist to trim down as much wiring as possible while also soldering parts like the UPS board and LCD display directly onto the Raspberry Pi. Despite literally and figuratively cutting every possible corner to make room for all of the components, the final result still required swapping out the tin’s hinges with slightly larger replacements to ensure the case could close shut.
With every hurdle cleared, it was simply a matter of booting up the contraption to give it a test run. Exercising Ingenuity says the final product worked flawlessly, and he was even able to program a small motor to run using his Altoid cyberdeck. Actually typing on the keyboard still looks like a labor of love, but the overall result remains very cool. Its inventor even made all of the designs available online for free, in case any aspiring cyberpunks are looking to recycle an old mint tin.

Parents around the world are responding to growing research showing that excessive screen time, especially for young children, may have negative cognitive effects. But what happens when a well-meaning parent wants to introduce their child to subjects intrinsically linked to screens, like computer programming? A new learning series from Japanese public broadcaster NHK called Texico aims to help solve that dilemma by using paper, plastic toys, and everyday objects to break down the core concepts and strategies essential to programming.
Each episode in the series runs about 11 minutes and focuses on key concepts including analysis, combination, abstraction, and simulation. The goal, NHK says, is to help children “learn the principles of programming without even touching a computer.”
In one episode, a toy train on a plastic track approaches a lowered rail crossing. Viewers are asked to visualize what will happen when the train makes contact with the barrier. In this case, both the train and the lowered rail continue moving forward.
The next segment complicates the scenario: the track now forms a circle, with the train, rail, and a wooden triangle block all positioned at different points. When the rail moves, so does the block. Viewers are asked to recall what happened in the previous example and apply that logic to the new configuration, essentially practicing the kind of mental simulation that underlies real programming work.
Another episode teaches foundational logic by asking viewers to tear a sheet of paper into nine pieces. A teacher then selects one piece and instructs the viewer to write a number from one to nine and place it face down. The viewer then writes the remaining numbers on the other pieces, also face down, so the teacher can’t see it. The teacher then somehow correctly guesses which piece holds which number.
But the trick isn’t magic. Instead, it has everything to do with the geometry of tearing paper. It’s revealed that the first piece the teacher selected was the center of the sheet. When paper is torn into nine equal pieces, the center piece is the only one without any straight edges. So when the teacher went to identify it, they simply looked for the piece that didn’t look like the others.
It’s a simple but elegant demonstration of the kind of pattern recognition that programmers rely on constantly.
“If you think hard enough, you can see the underlying logic,” a voice in the video says, followed by the slightly creepy musical mantra “Texico, Texico, Texico.”
Offline approaches to teaching computer concepts provide a way for newcomers of all ages interested in coding to get their feet wet without having to deal with distracting screens. For many, that’s a welcome reprieve. A recent YouGov poll found that more than half (57 percent) of adults in the United States spend at least five hours per day looking at screens. All that time starting into the digital glow has been shown to interfere with sleep and, in some cases, even contribute to anxiety and other mental health issues.
Screenless learning could also prove popular as parents and school districts push back against what many now see as an overreliance on screens. More than 35 states have enacted policies limiting smartphone use in classrooms. Districts in California and Oregon have recently gone further, adopting rules that restrict student use of laptops and tablets and prioritize pen and paper. Should that trend spread, it would mark a stark departure from the past two decades, during which “EdTech” was enthusiastically embraced and widely deployed in classrooms across the country.
“We are prioritizing developmentally appropriate learning during the most critical period for language, social, and cognitive development,” Jeanne Grazioli, a superintendent in a Southern Oregon schools district said after they moved to reduce screen time.
And while the debate over screens is far from settled, there is growing evidence that introducing concepts through analog methods pays dividends later on. In his recent book The Digital Delusion, neuroscientist and educator Dr. Jared Cooney Horvath points to research suggesting that students who learn to write by hand retain an advantage over those who move straight to typing, despite the fact handwriting has become increasingly less common in daily adult life.
”Many people believe that thinking happens entirely in the brain, as if we’re just gray matter hitching a rise inside a body,” Horvath writes. “But this misses something essential: we don’t merely have bodies—we are bodies. Learning doesn’t arise from the brain alone, it emerges from the rhythms, movements, and sensations of our entire physical selves.”
“Put simply, handwriting builds a foundation that typing cannot,” he adds.
Something similar may be at work when children learn programming basics through analog tools. And even if future research doesn’t bear that out conclusively, Texico offers something valuable on its own terms: a set of refreshing, screen-free puzzles that challenge young learners (and at least one adult tech writer) to flex their critical thinking skills.

Bagpipes: You either love ‘em or you hate ‘em. But even among the instrument’s diehard defenders, most wouldn’t spend years designing, building, and perfecting an electromagnetic variant. But that’s exactly what one intrepid hobbyist in the United Kingdom has accomplished—although he first began toying with the idea 30 years ago.
“This project started back in 1996 when I hacked an Irish Uilleann bagpipe chanter by replacing the cane reed with a homemade reed made from carbon steel,” he explained on his Hackaday project page.
Although most famously associated with Scotland, various iterations of bagpipe instruments are documented in regions around the world like North Africa, East Asia, and the Persian Gulf. The Uilleann or Irish pipes date back to the 18th century and operate similarly to their Scottish relatives. To play them, a wearer operates small bellows strapped around the waist to blow relatively dry air through pipe reeds while using them like flutes. Uilleann pipes typically encompass two full octaves and produce a sound that many consider more melodic and mild than Scottish bagpipes.
This doesn’t mean they’re quiet, of course. In fact, their earliest versions could often be found on the battlefield as morale boosters. Although, the invention of electric instruments meant that even the most robust pipes couldn’t overshadow an amplifier cranked to its maximum. This posed a problem to the modernized version’s inventor.
“I desperately wanted to play the pipes in a rock band and I knew that I would only be able to sonically compete with an electric guitar by fitting an electromagnetic pickup next to a steel reed,” he explained.
Wielding a workaround may sound like a lot of work, especially when a musician could hypothetically just place a microphone near their traditional bagpipes. While certainly possible, it’s still difficult for the performer to actually hear themselves on stage compared to the electric instruments and drums. On top of that, standard microphones pick up a lot of background noise and produce feedback in stage monitors. Constructing a steel reed bypasses these issues entirely.
“Jimi Hendrix-type feedback can still be created but only by turning up the monitor amp really high and physically shoving the instrument into the speaker,” the creator wrote, adding that he can also employ the same effects used by guitarists, including distortion, pitch shifters, and delays.
The modern updates don’t end there, either. While the bellows bag is crafted from goat skin, it’s basically an exterior cosmetic accessory that houses another bag made from the same vinyl used in car seat covers. That’s all well and good—but how does it play?
“Playing gigs with this instrument, people would crowd around to watch and guitarists at the back would be scratching their heads thinking ‘That sounds like an electric guitar, but it definitely is not an electric guitar and you definitely can’t get an electric guitar to sound like that!’” he wrote.
While the full plans aren’t available online, fans of the sound can check out the inventor’s website to hear multiple original songs featuring the electro-bagpipes.

Costco is famous for selling everyday products in large bulk quantities, be it a 40-pack of batteries or quarts of soy sauce. Then there are the not-so-common products like vending machines, coffins, and even entire barns. Knowing the retailer’s reputation, it’s understandable when people fall for hoax Costco purchases that occasionally go viral online.
Recently, a video showcasing a 200-foot-long, inflatable lazy river available from Costco has spread across social media. Posted by an Instagram page called The Inspiring Designs Net, the clip features a timelapse setup of the pool followed by a woman gleefully enjoying the circuit in her backyard. Despite the account swearing the lazy river is, “an absolute must for hot summer days,” the sad fact is that no such product exists. In reality, it’s yet another example of AI-generated clickbait that continues to flood the internet.
Many social media accounts now routinely churn out similar content solely to rack up page views, which are monetized through ad services. In this case, the faux-Costco lazy river has garnered well over 15 million views so far since it was uploaded on June 4. Many commenters were apparently fooled by the realistic scene, although others highlighted some telltale signs of AI slop. Most notably? The woman in the video looks incredibly dry despite lounging in her backyard lazy river.
Other examples to dupe unsuspecting viewers earlier this year included photos of North Carolina horses wrapped in fiberglass insulation to keep warm during a winter storm, as well as heated aboveground tunnels for dogs in Hungary. But while those are relatively absurd examples, a huge inflatable river admittedly sounds exactly like the type of thing Costco might sell. It may not exist now, but maybe it will inspire a call to action.
