Traditional channel hopping anti-jamming approaches using fixed patterns are ineffective against such dynamic jamming attacks. Although the emerging deep reinforcement learning (DRL) based dynamic channel access approach…

Privacy isn’t dead. Just ask Kristi Noem.The Department of Homeland Security secretary has spent 2025 trying to convince the American public that identifying roving bands of masked federal agents is “doxing”—and that revealing these public servants’ identities is “violence.” Noem is wrong on both fronts, legal experts say, but her claims of doxing highlight a central conflict in the current era: Surveillance now goes both ways.Over the nearly 12 months since President Donald Trump took office for a second time, life in the United States has been torn asunder by relentless arrests and raids by officers from Immigration and Customs…

Samsung is betting big on its in-house Exynos SoCs, with reports suggesting that the upcoming Galaxy S26 series will feature the recently released Exynos 2600 chipset. Built on a 2nm manufacturing process, the chip promises notable performance and efficiency gains thanks to a redesigned 10-core CPU, a new Xclipse 960 GPU, and an upgraded built-in NPU.

According to a fresh report from Hankyung (via Android Authority), Samsung has developed its own GPU architecture and could debut it with the Exynos 2800 in 2027. This means the Galaxy…

FAQs What does “non-toxic” mean for cookware? Unfortunately, non-toxic doesn’t have a standard (or legally enforceable) definition, but it’s generally considered to mean “not harmful” to our bodies and environment. You’ll often find it in reference to ceramic-coated and other Teflon-free pans. Because coating formulas are usually proprietary and there’s not enough human-based research around cookware in general, it’s hard to know for sure if any pot, pan, or tool is entirely free of potential harm. If modern, synthetically coated cookware gives you pause, consider time-tested materials like stainless steel, cast iron, carbon steel, and enamel. Why We’re the Experts

It was a normal day when Jay Gibson got an unexpected notification on his iPhone. “Apple detected a targeted mercenary spyware attack against your iPhone,” the message read. Ironically, Gibson used to work at companies that developed exactly the kind of spyware that could trigger such a notification. Still, he was shocked that he received a notification on his own phone. He called his father, turned off and put his phone away, and went to buy a new one. “I was panicking,” he told TechCrunch. “It was a mess. It was a huge mess.”   Gibson is just one of an…

YouTube Julius Makes creates a Bluetooth-to-tape live converterAdds instant analogue crunch to streaming music playlistsIt’s just a one-offHere’s something we (sadly?) won’t see at CES 2026, but that I love: YouTuber Julius Makes has created a device to offer “Bluetooth streaming on real cassette tape”. It’s a one-off bit of fun rather than something you can buy, but for people of a certain era, it might be tempting if were a real product.He explains the full process in the video below (via Hackaday), but it works by receiving the Bluetooth signal and converting it to analogue like any of the…

Growing up, weekends consisted of trips to the movies and amusement parks—and Costco. My mom would gather my sisters and me in the minivan, and we’d trudge along while she did grocery shopping for the week. If we behaved, we’d be rewarded with a stop at the food court, where we’d order a piping hot slice of pizza. To this day, the food court’s giant pizza continues to draw in a plethora of hungry customers, and I’ve always been curious about its lasting appeal. The Reason Costco Pizza Tastes So Good The main answer is simple, and it has everything…

Key Takeaways Adding mayonnaise to scrambled eggs creates a silky, creamy texture every time.The fat and acidity in mayo prevent overcooking and keep the eggs tender and soft.Alton Brown’s science-backed trick is simple, quick, and delivers consistent results. Scrambled eggs are my go-to lazy-day meal. Whether it’s breakfast, lunch, or even dinner (paired with an obligatory avocado toast), they’re quick, satisfying, and endlessly customizable. But there’s one thing I’m picky about: scrambled eggs should be silky-smooth and creamy, never dry. My usual soft and custardy scramble is a cross between the French and American styles. I heat a copper-bottomed skillet…
