This Shark Cordless Vacuum Is Nearly Free for Prime Day, Amazon Sold 20,000 in Just a Few Hours

Amazon brought forward Prime Day this year by a week, and the weekend’s best deals are already out there. That doesn’t leave you much time if you want to get your hands on one of the most popular deals before they are… gone. The best-selling cordless vacuum on Amazon from Shark is currently being offered at an all-time low price. Over 20,000 units have been sold in only a few hours, reports Amazon, and with demand this high, it could be gone tomorrow. It’s a no-brainer at this price point: ther

Watch TikTok Sensations Savannah Bananas Free on Your Roku Screen

There's a chance your TikTok feed has slipped in a few clips of the Savannah Bananas, an exhibition baseball team whose antics and gameplay style may remind you of the Harlem Globetrotters. In a league of their own, -- they play Banana Ball and no longer belong to other leagues -- the team can be seen dancing, singing and throwing curveballs on social media and your TV screen. This weekend, you can stream a game for free on the Roku Channel. If coordinated choreography for songs like the Cupid

12 Best Kids Headphones (2025), Hearing Protection and More

Protect Those Headphones Satechi 2-in-1 Headphone Stand Photograph: Julian Chokkattu Even durable headphones are easy to damage. We have lost pairs to folks standing on them, cats and robot vacuums attacking the cables, and chairs rolling over them. I have learned that a stand or holder is worth the investment if it keeps those cans off the floor. Even if your kids only sometimes remember to use it, that could extend the likely lifespan of their headphones. We use the Satechi 2-in-1 Headphone

Researchers seek to influence peer review with hidden AI prompts

In Brief Academics may be leaning on a novel strategy to influence peer review of their research papers — adding hidden prompts designed to coax AI tools to deliver positive feedback. Nikkei Asia reports that when examining English-language preprint papers available on the website arXiv, it found 17 papers that included some form of hidden AI prompt. The paper’s authors were affiliated with 14 academic institutions in eight countries, including Japan’s Waseda University and South Korea’s KAIST

Atomic "Bomb" Ring from KiX, 1947 (2020)

Release date: 1947 | Where to purchase: eBay 1947 | “It’s a seething scientific sensation!” In 1947, General Mills’ KiX cereal brand offered the Atomic “Bomb” Ring as a premium in exchange for 15 cents plus a cereal box top. Also known as the Lone Ranger Atomic Bomb Ring, it was a reflection of the public’s preoccupation with the power and potential of atomic energy at the time. The ring had an adjustable gold-coloured band with lightning-blast explosions on its sides. An aluminum warhead was

New study offers clues about what makes someone cool

Is there a secret sauce that helps explain why people as different as David Bowie, Samuel L. Jackson and Charli XCX all seem so self-assured and, well, cool? A new study suggests that there are six specific traits that these people tend to have in common: Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous. The study, which was published on Monday in the Journal of Experimental Psychology: General, surveyed nearly 6,000 participants from

Development of a transputer ISA board

Development of a transputer ISA board I developed software for transputers in the years 1993-1996. A few months ago, I wrote some articles about my experiences, and most recently I developed a transputer emulator in Javascript After my transputer emulator in Javascript was working, I got curious about running my software on a PC computer. I have several PC motherboards with ISA connectors, and I decided to build a card compatible with the Inmos B004 (a single board to test transputer processor

How Stablecoins Became the Digital Gold Standard

Recently, I met someone who is fluent in Chinese through Skewer Coaching. We talked about apps that are frequently used in China, and I told them about the ones I have used. Even those who don’t know much about China have probably heard of WeChat. There is even a joke that you can’t do almost anything in China without WeChat. Ordering food, calling a taxi, shopping, making payments, and even using government services can all be done within WeChat. Compared to KakaoTalk or Naver, which are common

Nothing's untestable

Vidhi Katkoria Technical Writer Nothing's untestable As the co-founder of HashiCorp, Mitchell has been instrumental in the development of tools that many of us use daily, like Vagrant, Terraform, Vault, and more. He also helped shape the initial testing strategies for them, gaining hard-won insights into testing complex software along the way. At BugBash, where everyone is a testing nerd (or at least wants to be), most of us have come across that one piece of code that cannot be tested. What d

Take Two: Eshell

30 Jun 2025 Charles Choi This is a contribution to the Emacs Carnival 2025-06: Take Two collection of posts on Christian Tietze’s blog. My first take with Eshell many years back did not leave a good impression. My early expectations was that it should act like any other shell, only to be unpleasantly surprised by it. It took a long time for me to warm up to Eshell. Upon reflection, it was because I wasn’t ready for it. Now Eshell is an inseparable part of my Emacs experience. Paradoxically th

Hidden interface controls that affect usability

Philip Kortum In the early 1960s, Douglas Engelbart [1] first introduced the notion of "knowledge in the world" versus "knowledge in the head" for computer interfaces—an idea that was later formalized and popularized by Donald Norman in his seminal book The Psychology of Everyday Things. From an interface design standpoint, knowledge in the world simply means that the controls you need are visible, and the identification and operation of these controls can be done through recognition rather tha

Chasing Hobbies over Achievement Boosts Happiness (2023)

Summary: Individuals emphasizing freedom and hobbies experienced a boost in well-being, whereas those prioritizing achievement felt less happy. The research showed that valuing ‘hedonism’ and ‘self-direction’ led to increased happiness across India, Turkey, and the UK. In contrast, ‘achievement’ and ‘conformity’ values showed no direct happiness benefits. The findings spotlight the importance of balancing life pursuits for mental health. Key Facts: Prioritizing freedom led to a 13% increase

Volunteer finds Holy Grail of abolitionist-era Baptist documents

By MICHAEL CASEY GROTON, Mass. (AP) — Jennifer Cromack was combing through the American Baptist archive when she uncovered a slim box among some 18th and 19th century journals. Opening it, she found a scroll in pristine condition. A closer look revealed the 5-foot-long (1.5-meter-long) document was a handwritten declaration titled “A Resolution and Protest Against Slavery,” signed by 116 New England ministers in Boston and adopted March 2, 1847. Until its discovery in May at the archives in Gr

Why the simplest desktop agent abstraction wins

This is first post in a series about the design and implementation of Bytebot . Give us a star on our open source repo . We’re still in the early innings of AI agents. There are hundreds of companies building wrappers around LLMs, trying to make them more useful; more tool-aware, more stateful, more capable of completing tasks across applications. But most of them are barking up the same tree: they’re building agents that work by connecting APIs and tools in structured ways. Bytebot was born o

Operators, Not Users and Programmers

This post is part 0 of a multi-part series called “the computer of the next 200 years”. the modern distinction between “programmers” and “users” is evil and destroys agency. consider how the spreadsheets grow🔗 spreadsheets are hugely successful. Felienne Hermans, who has spent her career studying spreadsheets, attributes this success to "their immediate feedback system and their continuous deployment model": the spreadsheet shows you its result as soon as you open it, and it requires no steps

Injection Rejection (2006)

Matthias Winkelmann's company decided to go the ole' outsourcing route and hand off all development work for a fixed-bid project to a certain overseas company. As it turned out, the hourly rate for certain overseas programmers were less than half that of the in-house folks, so management did the math and figured they could profit that much more. The in-house programmers were told to spend "only a little bit of time" on the project -- no technical advice, no coding assistance, and no even lookin

OpenAI CEO Sam Altman says he's 'politically homeless' in July 4 post bashing Democrats

OpenAI CEO Sam Altman posted on X Friday, saying he finds himself "politically homeless" as the Democratic party is no longer aligned with encouraging a "culture of innovation and entrepreneurship." Altman, whose company is a leader in artificial intelligence, made the post in celebration of the Fourth of July, saying he is "extremely proud to be an American" and believes the U.S. "is the greatest country ever on Earth." He used the post to share some of his political ideology, saying he belie

Tesla Robotaxi Rider Gets Bizarre Call Saying She Has to Exit Vehicle Immediately

YouTuber and Elon Musk stan Ellie Sheriff had a bizarre experience during her first Tesla robotaxi ride in Austin, Texas. As seen in a video she shared on her channel, "Ellie in Space," over the weekend, Sheriff got a strange call from the EV maker mid-ride, asking her and her fellow passenger to literally leave the vehicle due to incoming weather. "So we had to get out of the robotaxi, because weather is coming in," Sheriff said in the video while standing in the middle of a windy field. The

As a Wear OS fan, I’m embarrassed to admit how excited I am for this watchOS 26 feature

Kaitlyn Cimino / Android Authority I rely on lists to keep my life running: grocery lists, packing lists, home improvement checklists, birthday gift ideas for my 19 nieces and nephews, and ongoing logs of thank-you notes for gifts for my own kid. My note-keeping apps aren’t just productivity tools; they’re the backbone of my sanity. So, when Apple announced that the Notes app is coming to Apple smartwatches via watchOS 26, my ears perked up. Do you use note-taking apps on your smartwatch? 171

Apple is reportedly working on a cheaper MacBook, but will it matter?

This week, we heard some news from analyst Ming-Chi Kuo about Apple entering a new segment of the laptop market. The company is reportedly working on a new MacBook at a lower starting price point than the MacBook Air, and it’ll apparently pack the A18 Pro chip found in iPhone 16 Pro and iPhone 16 Pro Max. While a cheaper MacBook is certainly a welcome add, the question truly stands: will Apple do it properly, or will it serve as another decoy model? Rumor refresh To quickly recap, the cheaper

Xbox's sci-fi looter-shooter Blackbird was scrapped even after leaving execs 'blown away'

Xbox was well on its way to delivering a sci-fi stylized game with plenty of exciting movement mechanics before an abrupt change of heart. The upcoming third-person shooter RPG codenamed Blackbird from ZeniMax Online Studios, which developed The Elder Scrolls Online, has been "shelved indefinitely," according to an exclusive report from Bloomberg. The report added that Xbox execs were "blown away" by the game and had "nothing but complimentary words," according to Bloomberg's sources. The excit

Just Ask for Generalization (2021)

Generalizing to what you want may be easier than optimizing directly for what you want. We might even ask for "consciousness". This blog post outlines a key engineering principle I’ve come to believe strongly in for building general AI systems with deep learning. This principle guides my present-day research tastes and day-to-day design choices in building large-scale, general-purpose ML systems. Discoveries around Neural Scaling Laws, unsupervised pretraining on Internet-scale datasets, and o

Pet ownership and cognitive functioning in later adulthood across pet types

Age-related cognitive decline is an increasingly pressing concern in public health, which may begin in early adulthood and accelerate with increasing age1,2. While much research is still investigating the precise mechanisms of cognitive ageing, previous studies have identified several contributing factors, including for example genetics, general health and lifestyle choices3,4,5,6,7. Cognitive decline is a major public health concern on both individual and societal levels due to its association
