On a drizzly and windswept afternoon this summer, I visited the headquarters of Rokid, a startup developing smart glasses in Hangzhou, China. As I chatted with engineers, their words were swiftly translated from Mandarin to English, and then transcribed onto a tiny translucent screen just above my right eye using one of the company’s new prototype devices.Rokid’s high-tech spectacles use Qwen, an open-weight large language model developed by the Chinese ecommerce giant Alibaba.Qwen—full name 通义千问 or Tōngyì Qiānwèn in Chinese—is not the best AI model around. OpenAI’s GPT-5, Google’s Gemini 3, and Anthropic’s Claude often score higher on benchmarks designed…

In November 2017, Bethesda Softworks and port specialists Panic Button performed what seemed like a miracle: They released a Switch port for id Software’s recent reboot of Doom. The game, a famously fast-paced, intense shooter with modern graphics, seemed ill-suited to Nintendo’s handheld and its capabilities, but despite some visual blurriness and a reduction in the frame rate, the game held up well on the hybrid system. In GameSpot’s 8/10 review of the Switch port, Peter Brown praised the game as “an impressive port that begs you to consider gameplay over graphics.”Doom was the first Switch “impossible port,” a colloquial…

If you are a car enthusiast, you know the feeling. You press the gas pedal, the engine roars, and you wait for that push back into your seat. But if you are building a serious race car, especially a Nissan GT-R, you might notice a problem. You have plenty of power, but you can’t use it all. The tires spin, the car fights for grip, and you lose precious time. To go fast, you need more than just a big engine. You need to get that power to the ground efficiently. This is where your wheels and tires come in.…

The presents are unwrapped, the cookies are crumbs, and that real Christmas tree will become a fire hazard soon enough. Most of us haul it out to the curb for our local sanitation departments to take care of, but some lucky trees make it into the paws of animals living in zoos.  Since 1978, the Cape May County Park & Zoo in Middle Township, New Jersey, has solicited donations of undecorated Christmas trees from the community and unsold trees from nearby businesses. The trees are then…

When US president Donald Trump launched his own meme cryptocurrency on January 17, days before his return to the White House, I was halfway up a Swiss alp, attending a crypto conference in the town of St. Moritz.Memecoins, which typically have no purpose beyond financial speculation, were having a moment. The previous year, millions of new memecoins had flooded the market; a few, like Fartcoin, had rocketed to billion-dollar valuations. Pump.Fun, a platform for launching and trading memecoins, had become one of the fastest-growing crypto launchpad businesses ever. Now, the soon-to-be president was getting in on the act.Over lunch on…

Liu Pengyu, a spokesperson for China’s U.S. embassy, rejected the notion that Chinese investments were violating people’s rights. In an email, Liu said the country’s Belt and Road Initiative, the umbrella for its overseas infrastructure investments, aims to support green economic growth.“The founding purpose of the BRI is to advance China’s cooperation with partner countries following the principle of mutual respect, equality, and mutual benefit, to help them develop the economy and shake off poverty, which is a human right they need more than any other,” Liu said.In Hungary, academics and environmentalists say, the investments have been accelerated by lax…

The most immediately striking difference is that Hyperkin’s product swaps the typical Xbox approach of asymmetric thumbsticks for the PlayStation’s horizontal layout. It also separates the D-pad (it’s one piece inside the pad, but splits its cardinal directions so each appears to be its own button), while the ABXY face buttons are spaced slightly further apart. Where the DualSense’s touchpad would sit, we have the Xbox home, menu, view, and share buttons, all blended in rather smartly. An LED ring around the home button just about echoes the lights running the periphery of the DualSense’s touchpad, although it’s really more…

Earth Directorate Commander Ash was sent to settle a labor strike issue on behalf of Auntie’s Choice, in an effort to gain favor with the corporate conglomerate. A bit of an outlaw, and someone who excels in shooting, lockpicking, and smooth-talking, I felt like my character was primed to work out a result that was favorable for the workers without too much of an issue.I was able to enter the closed-off facility and even nab some blackmail on the manager in charge before confronting her directly about the labor strike. I conveyed the workers’ demands, and expected to be able…
