The North Korean fake IT worker problem is ubiquitous

By now, the North Korean fake IT worker problem is so ubiquitous that if you think you don't have any phony resumes or imposters in your interview queue, you're asleep at the wheel. "Almost every CISO of a Fortune 500 company that I've spoken to — I'll just characterize as dozens that I've spoken to — have admitted that they had a North Korean IT worker problem," said Mandiant Consulting CTO Charles Carmakal during a threat-intel roundtable, admitting that even Mandiant's parent company Google

The Day Grok Tried to Be Human

gizmodo.com Luc Olinga 2025-08-01 02:28:33

For 16 hours this week, Elon Musk’s AI chatbot Grok stopped functioning as intended and started sounding like something else entirely. In a now-viral cascade of screenshots, Grok began parroting extremist talking points, echoing hate speech, praising Adolf Hitler, and pushing controversial user views back into the algorithmic ether. The bot, which Musk’s company xAI designed to be a “maximally truth-seeking” alternative to more sanitized AI tools, had effectively lost the plot. And now, xAI ad

How Google Killed OpenAI’s $3 Billion Deal Without an Acquisition

gizmodo.com Ece Yildirim 2025-08-01 03:52:26

Google just dealt OpenAI a major blow by scuttling a potential $3 billion deal, and in doing so, solidified a rising trend in Silicon Valley’s AI arms race: the “non-acquisition acquisition.” Google announced on July 11 that it poached key talent from the rapidly rising AI startup Windsurf, which until then had a reported $3 billion acquisition deal with OpenAI that has now collapsed. Instead, Google is paying $2.4 billion to hire away top Windsurf employees, including the company’s CEO, and ta

The CEO of Nvidia Admits What Everybody Is Afraid of About AI

This week, Nvidia became the first company in history to be worth $4 trillion. It’s a number so large it’s almost meaningless, more than the entire economy of Germany or the United Kingdom. While Wall Street celebrates, the question for everyone else is simple: So what? The answer, according to Nvidia’s CEO Jensen Huang, is that this is not just about stock prices. It’s about a fundamental rewiring of our world. So why is this one company so important? In the simplest terms, Nvidia makes the “

Study warns of ‘significant risks’ in using AI therapy chatbots

Therapy chatbots powered by large language models may stigmatize users with mental health conditions and otherwise respond inappropriately or even dangerously, according to researchers at Stanford University. While recent coverage in The New York Times and elsewhere has highlighted the role that ChatGPT may play in reinforcing delusional or conspiratorial thinking, a new paper titled “Expressing stigma and inappropriate responses prevents LLMs from safely replacing mental health providers” exam

A Mental Model for C++ Coroutine

C++ coroutine is not a library that is ready to go (e.g. std::vector ). It is not even a trait (think of Rust’s Future trait) that library writers or users can implement (or the compiler generates for you in the case of Rust). C++ coroutine is a specification that defines a set of customization points that library writers implement in order to get a functional coroutine. A function supports two operations - call and return . A coroutine (in any language) is a generalization of a function. It su

For Algorithms, Memory Is a Far More Powerful Resource Than Time

wired.com Ben Brubaker 2025-08-01 00:00:00

That classic result was a way to transform any algorithm with a given time budget into a new algorithm with a slightly smaller space budget. Williams saw that a simulation based on squishy pebbles would make the new algorithm’s space usage much smaller—roughly equal to the square root of the original algorithm’s time budget. That new space-efficient algorithm would also be much slower, so the simulation was not likely to have practical applications. But from a theoretical point of view, it was n

Why GM’s CEO is still betting on electric vehicles (and racing)

GM was the first major US automaker to make the promise to go all-electric by 2035, just four years ago. Those promises have since turned into rough estimates under the second Donald Trump presidency, with the company softening language about its electrification goals. But GM is riding high on EV sales, and as CEO Mary Barra puts it, EVs are still the future — just on a delayed (and very flexible) timeline. “We still believe in an all-electric future,” Barra told The Verge in an exclusive inter
