Xpeng is seen by some as the Chinese answer to Tesla, not only because of its emphasis on tech, particularly self-driving, but also in terms of positioning. One of three Chinese EV start-ups listed in the US for a long time, it was best seen as an also-ran thanks to disappointing sales against better-known Nio and sales powerhouse Li Auto.That all changed for Xpeng last year thanks to two new models. Sales of the first, the Xpeng Mona M03, began in August and quickly the car became Xpeng’s best-selling model. Then, in November sales began of XPeng P7+, and it…

Google’s most expensive AI model seems to have crossed a major milestone: Beating a 29-year-old video game. Last night, Google CEO Sundar Pichai posted triumphantly on X, “What a finish! Gemini 2.5 Pro just completed Pokémon Blue!” To be clear, the Gemini Plays Pokemon livestream was created by (in his own words) “a 30 year old software engineer unaffiliated with Google” who goes by Joel Z. But Google executives have been cheering the effort on. For example, Logan Kilpatrick, the product lead for Google AI Studio, posted last month that Gemini was “making great progress at completing Pokémon” and had…

The CMF Phone 2 Pro has a triple-camera system, and the third camera isn’t some silly 2-megapixel macro sensor like on most cheap phones. You’re getting a proper, versatile camera array usually found on pricier devices, with a 50-MP main camera, a 50-MP telephoto camera with 2X optical zoom, and an 8-MP ultrawide. There’s a 16-MP selfie camera on the front.These sensors can struggle in high-contrast scenes, like when you have bright highlights on a sunny day mixed with shadowy areas—things can blow out a bit. In low light, you have to stay still to avoid a blurry image. But…

Honorable MentionsWe haven’t tried a vacuum yet that we absolutely hate. These ones below are solid vacuums, and in some cases are much cheaper than our top picks, but we didn’t like them as much.Dirt Devil Power Swerve Pet Cordless Stick Vacuum for $93: We previously recommended this as a budget pick. It’s a good vacuum for the money, but there are mixed results on how long the battery will last and the build quality.Eureka Innova Cordless Stick Multi-Surface Vacuum for $207: This is a good stick vacuum at a reasonable price. It cleaned up a litter mat especially well,…

The vacuum has six RGB infrared cameras on the front, top, and back, which means that it can see in color and in darkness—you don’t have to have all the lights on for it to work, unlike a robot vacuum that uses basic optical sensors. It took a few minutes to map my home. The app is incredible. It’s a weirdly accurate 3D rendering of my home, differentiating not only the floor surfaces but also furniture and items several feet up.The app has several buttons that you can toggle. You can change the rendering style to make the map less…

Python is a high-level, interpreted programming language that has gained immense popularity in data science, machine learning, and web development. One of Python’s most useful built-in functions is the count() function, which allows you to count the number of occurrences of a particular element in a python list count or a tuple. In this article, we will learn how to use the count function in Python and explore its practical applications. Python’s count() function is a built-in function that allows you to count the number of times an element appears in a list or tuple. This function can be handy…

At the storefront event, a man waiting outside told me he’d booked an appointment for 11:30 but noted he was an hour early and wasn’t allowed to come inside yet. He was visiting from Poland and said his boss had attended the party the night before and was “super hyped” about the orb concept. “I don’t know if it’s gonna be like a worldwide revolution, but I just want to be on the wave,” he said.“My only hesitation is that they are super huge,” he added. “I’m pretty afraid that they can actually do some stuff that we will not…
