The first thing I noticed about the NordicTrack Commercial 2450, NordicTrack's newest addition to its commercial treadmill series, is the touchscreen. It has a 22-inch HD touchscreen that resembles a desktop computer screen, so it's huge. It also tilts and pivots so you can adjust it for different uses, like if you want to take workout classes on the floor. The treadmill itself is also on the bigger side since it's a commercial treadmill, but it does fold up using its easylift assist feature, so
No matter how old you get, the back-to-school season will always bring a desire to shop. So, sales at this time of year are always more than welcome — especially when they're on some of our favorite devices. Such is the case with the 10 percent discount currently available on the Sonos Era 100. Our choice for midrange smart speaker is down to $179 from $199 as part of a larger sale on the Sonos website. The same price is available on Amazon, as are some more deals on Sonos products. Sonos debu

But in some ways, the proof was a bit unsatisfying. Jitomirskaya and Avila had used a method that only applied to certain irrational values of alpha. By combining it with an intermediate proof that came before it, they could say the problem was solved. But this combined proof wasn’t elegant. It was a patchwork quilt, each square stitched out of distinct arguments. Moreover, the proofs only settled the conjecture as it was originally stated, which involved making simplifying assumptions about th
It’s a well-worn trope in science fiction. We see it in Stanley Kubrick’s 1968 movie 2001: A Space Odyssey. It’s the premise of the Terminator series, in which Skynet triggers a nuclear holocaust to stop scientists from shutting it down. Those sci-fi roots go deep. AI doomerism, the idea that this technology—specifically its hypothetical upgrades, artificial general intelligence and super-intelligence—will crash civilizations, even kill us all, is now riding another wave. The weird thing is th

#macOS dotfiles should not go in ~/Library/Application Support One of my pet peeves is when command-line tools look for user configuration files in ~/Library/Application Support when running on macOS. In addition to offering poor ergonomics for users, I believe this behavior is incorrect according to the documentation which is cited to justify it. Instead, command-line tools should implement the XDG Base Directory Specification and look for configuration files in $XDG_CONFIG_HOME , which defaul
The US Attorneys General of 44 jurisdictions have signed a letter [PDF] addressed to the Chief Executive Officers of multiple AI companies, urging them to protect children "from exploitation by predatory artificial intelligence products." In the letter, the AGs singled out Meta and said its policies "provide an instructive opportunity to candidly convey [their] concerns." Specifically, they mentioned a recent report by Reuters, which revealed that Meta allowed its AI chatbots to "flirt and engag
Months before a jury awarded a $242.5 million verdict against Tesla over its culpability in a 2019 fatal crash, the automaker had a chance to settle for $60 million. Instead, Tesla rejected that offer, according to new legal filings that were first reported by Reuters. The settlement proposal, which was made in May, was disclosed in a filing that requested Tesla cover legal fees for the plaintiffs in the case. Earlier this month, a jury in federal court in Miami found Tesla partly to blame f

Companies with AI chatbots love to highlight their capability as translators, but they still default to English, both in function and in the information they are trained on. With that in mind, Humain, an AI company in Saudi Arabia, has now launched an Arabic-native chatbot. The bot, called Humain Chat, runs on the Allam large language model, according to Bloomberg, which the company claims was trained on “one of the largest Arabic datasets ever assembled” and is the “world’s most advanced Arabi
Cooking oil can completely transform a dish, but using the wrong one can ruin it. While olive oil is a go-to for many home cooks, it isn't always the best choice. The reason? Its lower smoke point means it can burn at high temperatures, leaving food with an unpleasant, bitter taste. For frying, searing or any other high-heat cooking, reach for neutral oils like canola, avocado or grapeseed instead. They can withstand hotter temperatures and deliver a cleaner, crisper finish. By matching the rig
Nick Clegg, a former Meta executive who left the company at the start of this year, has led many lives. Before jumping ship to the tech world, he was a deputy prime minister of the United Kingdom, a leader of the UK's Liberal Democrat party, and a member of Parliament — and still, the hubris and wealth he saw in Silicon Valley startled even the well-heeled British politico. In an interview with The Guardian pegged to the release of his new book, "How To Save The Internet," Clegg took aim at th

Synchronized demand is the moment a large cohort of clients acts almost together. In a service with capacity $\mu$ requests per second and background load $\lambda_0$, the usable headroom is $H = \mu - \lambda_0 > 0$. When $M$ clients align—after a cache expiry, at a cron boundary, or as a service returns from an outage—the bucketed arrival rate can exceed $H$ by large factors. Queues form, timeouts propagate, retries synchronize, and a minor disturbance becomes a major incident. The task is to

At Meta’s Q2 2025 earnings call at the end of July, Mark Zuckerberg didn’t hold back. “If you don’t have glasses that have AI,” he warned, “you’re probably going to be at a pretty significant cognitive disadvantage compared to other people.” Forget smartphones. According to Zuck, the real interface of the future is what’s sitting on your nose. These AI-powered specs, he argues, will “see what we see, hear what we hear, and talk to us” in real time—offering a kind of digital copilot for everyday
Temporary Suspension of Acceptance of Mail to the United States Due to Changes in U.S. Customs and Regulations On July 30, 2025, the U.S. government issued an executive order titled “Termination of De Minimis Treatment for All Countries” regarding mail to the United States. Under this executive order, starting August 29, 2025, mail containing goods imported for personal use (taxable mail) will no longer be eligible for duty-free treatment, and tariffs will be imposed. On August 15, 2025, U.S.
I have mixed feelings about Daily Harvest smoothies. They're tasty but expensive, and some are high in sugar. And making smoothies from scratch doesn't take much time if you have the right ingredients on hand. For me, the real star of this 100% plant-based and gluten-free meal service is its premade pastas. They're healthy, filling, easy to prepare -- heat them in a skillet and the frozen cubes of sauce bring the dish together -- and cost under $11 per bag, each containing two full servings. As

This weekend, movie history was made. For the first time ever, Netflix had the number one movie at the box office with its megahit KPop Demon Hunters. However, while every single other film distributor would’ve celebrated this fact, the streamer didn’t report the numbers. Instead, it put the version of the film in theaters immediately onto its streamer. The message was clear. This wasn’t meant to be a huge money grab or play for theatrical dominance. It was more of a thank you to the fans who st
Greenhouse gas reduction is no longer a priority for the US government, but if you're looking for a new vehicle and want to buy something with the lowest life cycle carbon emissions, you're best off looking for a compact with a small battery. That's one of the findings of a comprehensive study from a group at the University of Michigan that calculates the overall cradle-to-grave carbon impact for different types of vehicles, including factors like powertrain options, location (within the country
The Toxic Avenger, a semi-reboot of the 1984 superhero splatter-fest, made the rounds of the festival circuit back in 2023. But all the violence and gore scared off most distributors, so the film—starring Peter Dinklage (Game of Thrones) in the title role—has been languishing in the vault for much of the last two years. Thanks to Cineverse, The Toxic Avenger is finally coming to select theaters this weekend. And thanks to the folks at Bloody Disgusting (a Cineverse subsidiary), we've got a trai
Struggling between the comfort of an individual contributor (IC) role and the desire to move into software engineering leadership? It’s a tough fork in the road that many engineers face. The idea of stepping away from hands-on technical work to move into leadership requires mastering new skills, stepping into the spotlight, and strategic thinking. It feels like a major departure from their comfort zone of code development, testing, and debugging. But the truth is, growth happens outside the comf
