The Kremlin's Most Devious Hacking Group Is Using Russian ISPs to Plant Spyware

The Russian state hacker group known as Turla has carried out some of the most innovative hacking feats in the history of cyberespionage, hiding their malware's communications in satellite connections or hijacking other hackers' operations to cloak their own data extraction. When they're operating on their home turf, however, it turns out they've tried an equally remarkable, if more straightforward, approach: They appear to have used their control of Russia's internet service providers to direct

Arm stock tumbles on chip designer's muted profit forecast

Shares of Arm Holdings plunged 12% on Thursday after the chip designer offered muted guidance for earnings. Second-quarter adjusted earnings will be between 29 cents and 37 cents per share, Arm said late Wednesday. Wall Street had projected 35 cents per share. The company forecast second-quarter revenue of $1.01 billion to $1.11 billion, which was in line with consensus estimates of $1.05 billion. The concerning outlook was amplified by commentary from Arm CEO Rene Haas, who indicated the com

What is gVisor?

It has been a really long time since I last wrote something here as life happens, things get busier, etc etc. I am now trying to get back into writing things down and here we go! So, imagine a tool or a service that allows you to run some arbitrary code via a shell. Either through a ssh or more commonly, via a web terminal. How does these tools isolate your code from other people’s code and vice versa ? How come you cannot see other people code or processes ? The first thing you probably be th

Ofcom investigates 34 porn sites over age checks 2 hours ago Share Save Liv McMahon Technology reporter Share Save Getty Images Ofcom is investigating four companies, operating a total of 34 porn sites, over whether they are complying with its new age check requirements. The regulator said on Friday more than 6,000 sites allowing pornography and other adult content would start using "highly effective" tools to verify or estimate whether users were over or under the age of 18.

New DNA Map of the Pistachio Could Create Better Varieties

California produces 99% of the nation’s pistachios, generating nearly $3 billion in economic value in the state. But pistachios have been slightly understudied in part because of the lack of a high-quality map of their DNA. University of California, Davis, researchers have now generated the most comprehensive genome sequence of the pistachio, allowing plant breeders to create better — perhaps more nutritious — varieties. They’ve also detailed how pistachio nuts develop, which will help farmers m

Trump will end the de minimis exemption for low-cost global shipments

President Donald Trump's latest economic move is to halt the de minimis exemption, a provision that made international shipments of low-value items cheaper. When the exemption ends on August 29, shipments valued at or under $800 will be subject to duty fees when sent by any carrier other than the international postal network, no matter what country they are coming from. According to the White House's announcement of this change, shipments will either be assessed with an ad valorem duty equal to

TernX Review (2025): Travel With Young Kids Just Got Easier

I procrastinated flying anywhere with my son until he was almost 3. There were so many things needed—a car seat! Stroller! In-flight entertainment! His own luggage! A crib when we landed!—that it felt like too much to coordinate. And who can blame me? It's just parenting in a new location, after all, rather than a vacation. Still, a trip we wanted to take finally presented itself. We booked a long weekend in San Francisco and the nearby wine country to see family and friends we haven't seen sin

Men Born in the Summer Are More Likely to Be Depressed, Study Finds

There really might be something to the idea of summertime sadness, at least for boys. A study finds that men born in the summer are more vulnerable to developing depression than men born at other times of the year. Researchers at the Kwantlen Polytechnic University in British Columbia, Canada, conducted the study, an international survey of adults. They found that men, but not women, were more likely to experience depression symptoms later in life if their birth occurred in the summer compared

YouTube will be included in Australia's social media ban for children after all

YouTube will be included in Australia's social media ban for children under 16, as reported by Bloomberg . The country's Labor government said that the site will be subject to the same rules as other leading platforms like Facebook, Instagram, TikTok and X when the legislation goes into effect this December. Australia had planned to exempt YouTube from the forthcoming social media ban, on the grounds that it's an educational tool. This irked other platforms, with Meta and TikTok urging the coun

Starlink Is Set to Receive Billions in Federal Subsidies but Analysis Says It Can’t Handle the Traffic

Key takeaways A new X-Lab analysis indicates Starlink can only support 6.66 households per square mile before speeds drop below FCC broadband minimums (100/20 Mbps). Currently, only 17% of Starlink users currently meet FCC broadband speeds, yet altered BEAD program rules could direct significant federal funds to Starlink as the lowest-cost option. While Starlink greatly improves internet access and quality for rural Americans, experts worry about its long-term viability for widespread broadban

Google says it never received a UK demand for encryption backdoor, unlike Apple

A hot potato: Google says that unlike rival Apple, it has not received a demand from the UK government to build a backdoor in its encrypted services. The tech giant had refused to answer a US Senator's question on the matter, but it has since confirmed it is not subject to a similar order as Apple. In a letter to the Director of National Intelligence, Tulsi Gabbard, Senator Ron Wyden, who serves on the Senate Intelligence Committee, wrote about the UK's "reported secret surveillance demands of

Linux 6.16: faster file systems, improved confidential memory, more Rust support

herraez/Getty Images The changes in the latest Linux kernel, Linux 6.16, may be small, but they include some significant ones. Linus Torvalds himself summed up this release as looking fine, small, and calm, but not "really not all that interesting (in all the best ways!)." Here's my list of what's new and improved. First, the Rust language is continuing to become more well-integrated into the kernel. At the top of my list is that the kernel now boasts Rust bindings for the driver core and PCI

YouTube is turning over age verification to AI

YouTube will start using machine learning to determine whether viewers should be on a teen account. The company said it plans to start using this AI application on a subset of US users in the coming weeks for a trial before rolling it out to the rest of the market. The tool will assess user behaviors including the types of videos being searched for, the categories of videos watched and how long the account has existed. When an account is deemed by machine learning to belong to a teen, YouTube wi

OpenAI is launching a version of ChatGPT for college students

A handful of college students who were part of OpenAI’s testing cohort—hailing from Princeton, Wharton, and the University of Minnesota—shared positive reviews of Study Mode, saying it did a good job of checking their understanding and adapting to their pace. The learning approaches that OpenAI has programmed into Study Mode, which are based partially on Socratic methods, appear sound, says Christopher Harris, an educator in New York who has created a curriculum aimed at AI literacy.

Learning Is Slower Than You Think

It was just a question over breakfast. “What’s a metaphor?” Mira asked her father, spoon halfway to her mouth. He began to explain, but she interrupted: “So it’s when something isn’t what it is—but also is?” There was a silence at the table—not confusion, but recognition. She had already touched it, before any definition arrived. Before a lesson plan or rubric could intervene. That moment—so small, so ordinary—was also everything. Because this is how real learning often arrives: sideways, u
