Opendoor stock pops 10% as CEO resigns following investor pressure campaign

Opendoor shares popped about 10% on Friday after CEO Carrie Wheeler said she's resigning from the online real estate company, which has seen a surge in recent interest from retail investors. Pressure began building on Wheeler, who took over the top job in 2022, after the company's quarterly earnings report earlier this month failed to reassure investors that a turnaround is underway. The stock is up more than sixfold since bottoming out at 51 cents in June, a price that put the company at risk

iPhone 17 Pro Max might have a camera advantage over iPhone 17 Pro

Apple’s big iPhone unveiling is just weeks away, and a new post from a Weibo leaker hints that there’s a surprise advantage coming to iPhone 17 Pro Max’s camera that may not be available on iPhone 17 Pro. Telephoto camera on iPhone 17 Pro Max may have unique advantage, per leaker Every year, Apple tends to do something a little different when it comes to its two Pro models. Sometimes the smaller and larger iPhone Pro are basically identical apart from size. No specific features are exclusive

Apple Watch Series 11: Three new features coming next month

A new wave of Apple Watch models is launching soon. Apple Watch Ultra 3 will rightfully get a lot of attention, but there’s a new Apple Watch Series 11 coming too—here are the rumored new features. #1: Upgraded S11 SiP Where the iPhone uses A-class chips like A18, and Macs and iPads often use M-class like M4, the Apple Watch has an S-class SiP (“System in Package”). Last year, Apple Watch Series 10 debuted a new S10 SiP. While Apple doesn’t always have new SiPs ready annually, recent leaks in

The $100 open-ear headphones that made me forget about my Shokz

I depend on earbuds to keep my runs from feeling like a chore. This is especially so during the hot summer months, when any distraction from the heat is a necessity. When I go on longer runs, I need earbuds that can not only tolerate my copious sweat, but also not constantly remind me that I have something on my ears. Because of the amount of sweat I produce when running, I can't wear traditional earbuds (I've destroyed at least a dozen pairs), which means I have to use either bone-conducting h

The SSD gadget that keeps my private data secure (while making me feel like James Bond)

Adrian Kingsley-Hughes/ZDNET Most of us already know that carrying unencrypted data on portable drives is a bad idea. The consequences of that data falling into the wrong hands can range from embarrassing to damaging to potentially opening up you or your company to legal headaches. But encrypting data on external drives can also be a pain. If you have to run separate applications, things quickly become a big hassle, and that's how data gets left unencrypted.

I let LLMs write an Elixir NIF in C; it mostly worked

This post documents how I built a cross-platform Elixir NIF in C to get on-demand up-to-date disk-usage stats without relying on os_mon and its disksup service. I had Grok 3 generate the initial C code and Makefile, then iterated through multiple code reviews by Gemini 2.5 Flash and GPT-5 to make it work on Linux, macOS, Windows, and the BSDs (except DragonFlyBSD). Along the way, I ran into typical LLM hiccups that speak volumes about the breathless hyperbole often peddled by LLM vendors, comput

The Timmy Trap

This is Part 2 of my LLM series. In Part 1, I discussed how in just a few short years, we went from the childlike joy of creating “Pirate Poetry” to the despair that our jobs would disappear. My main message was to relax a bit, as companies abuse the hype cycle to distort what is actually happening. In this post I want to talk about how we fall prey to this distortion: we perceive LLMs as intelligent when they aren’t. A recent post from Jeppe Stricker put me on this path. He wrote, “AI produces

German court declares Karl Marx's teachings unconstitutional

A court in Hamburg, Germany, has stated in the details of a ruling concerning a Karl Marx reading group that Marx’s teachings may be contrary to the “free democratic basic order.” On April 8, the “Marxist School of Politics and Culture Forum” (Masch) won its case against the State Office for the Protection of the Constitution (LfV) in the Hamburg Administrative Court. The court ruled that the authorities could no longer classify the Hamburg-based association as “left-wing extremist.” Masch had

Do Things That Don't Scale (2013)

Want to start a startup? Get funded by Y Combinator. July 2013 One of the most common types of advice we give at Y Combinator is to do things that don't scale. A lot of would-be founders believe that startups either take off or don't. You build something, make it available, and if you've made a better mousetrap, people beat a path to your door as promised. Or they don't, in which case the market must not exist. [ 1 ] Actually startups take off because the founders make them take o

Here Are the Winners of the 2025 Wildlife Photos of the Year Contest

Nature can be equal parts majestic, heartwarming, and terrifying. The winning entries of the 2025 BMC Ecology and Evolution and BMC Zoology image competition illustrate that complexity in spades. Biologists, zoologists, and paleontologists from across the world sent in submissions to this year’s contest. The photos were sorted into four categories: “Collective Social Behavior,” “Life in Motion,” “Colorful Strategies,” and “Research in Action.” But the overall winner (seen in the headline image

Open-Sourced AI Models May Be More Costly in the Long Run, Study Finds

As more businesses adopt AI, picking which model to go with is a major decision. While open-sourced models may seem cheaper initially, a new study warns that those savings can evaporate fast, due to the extra computing power they require. In fact, open-source AI models burn through significantly more computing resources than their closed-source rivals when performing the same tasks, according to a study published Thursday by Nous Research. The researchers tested dozens of AI models, including

Does Steven Spielberg’s ‘AI: Artificial Intelligence’ Play Differently Today?

Rewatching Steven Spielberg’s 2001 film AI: Artificial Intelligence, it feels as plausible as ever, but also more misguided. In 2001, AI was barely a thought in everyday life. It was the thing that destroyed the world in Terminator, and still a lofty goal in tech circles. Today, as the technology continues to grow and dominate daily conversation in almost every way, you may expect to watch the film and have a slightly new perspective. Some change in insight. Instead, the film falters as Spielber

Millions at Extreme Risk as Wet-Bulb Heat Smothers the U.S. This Weekend

Summer may be winding down, but oppressive heat and humidity will smother much of the Eastern U.S. this weekend. By Sunday, August 17, 38 million Americans will face “major” risk of heat stress, with another 7 million at “extreme” risk, according to the National Weather Service. The forecast calls for the highest temperature anomalies to spread from the Central Plains to the Midwest this weekend, with temperatures in the mid-to-upper 90s and low 100s Fahrenheit (mid-to-upper 30s Celsius), the N

The White House Keeps a ‘Loyalty’ Scorecard for Companies: Report

The White House has created a spreadsheet that rates hundreds of companies for their loyalty, according to a new report from Axios. And while that may not be entirely shocking news, given Donald Trump’s way of doing business, it’s worth stepping back and asking how news of a loyalty scorecard by a sitting president would’ve been received in the pre-Trump era. The rankings on the loyalty spreadsheet are currently determined by a given company’s perceived support of the so-called Big Beautiful Bi

US may purchase stake in Intel after Trump attacked CEO

Donald Trump has been meddling with Intel, which now apparently includes mulling "the possibility of the US government taking a financial stake in the troubled chip maker," the Wall Street Journal reported. Trump and Intel CEO Lip-Bu Tan weighed the option during a meeting on Monday at the White House, people familiar with the matter told WSJ. These talks have only just begun—with Intel branding them a rumor—and sources told the WSJ that Trump has yet to iron out how the potential arrangement m

Sam Altman Says ChatGPT Is on Track to Out-Talk Humanity

Never mind the GPT-5 complaints; Sam Altman says he believes ChatGPT is on track to have more conversations per day than all human beings combined. “If you project our growth forward, pretty soon billions of people a day will be talking to ChatGPT,” said the CEO of OpenAI during a dinner with journalists in San Francisco. “ChatGPT will be having more conversations, maybe, than all human words put together, at some point.
