Jason Hiner/ZDNET The hype continues to build around the arrival of Meta's futuristic Hypernova (a.k.a. Celeste) smart glasses, which will reportedly add a small heads-up display in one eye and a neural wristband (Ceres) to control the interface. These will reportedly cost around $800 and will be announced at Meta Connect on September 17. Some have even started calling these the next version of the current Meta Ray-Ban smart glasses.

Teeth whitening kits aren't exactly what most people would call riveting. I must say I was blown away by the entire Smile Brilliant process and package. I wasn't aware you could get custom-fitted whitening trays anywhere other than a dentist's office, but you can with Smile Brilliant. Wearing these whitening trays is just like wearing a retainer. They fit perfectly to your teeth because they're designed using putty impressions you make of your teeth. The process works like this: You order a kit

Comparison of different C libraries providing generic containers capabilities

Introduction The goal of this project is to compare several C libraries that provide some STL like capabilities of the C++ (container template) but are targeting classic C language. A STL like library for C is a C library providing several classic generic containers for the C language, like vector, list, sorted set, unordered_map, and so on.

HTC takes on Meta with the Vive Eagle smart glasses

HTC is once again attacking the wearable space with a pair of new smart glasses, the company announced. The Vive Eagle is a rival to Meta's Ray-Ban glasses with a fashion-foward lightweight design, open ear audio, voice-activated AI and an ultra-wide AI-powered camera. They look promising, if a bit expensive, but will only be available in Taiwan to start with. The Taiwanese firm clearly noticed that Meta's Ray-Ban smart glasses have been a surprise hit.

What we like about it: For those who want to avoid chemicals altogether, a lemon eucalyptus insect repellent is a gentler way to stave off bugs and their bites. I tried a few different lemon eucalyptus bug sprays, and Natrapel came out on top.

New Theory Could Dramatically Expand the Search for Aliens

gizmodo.com Gayoung Lee 2025-12-12 03:36:09

The search for alien life is largely centered on finding planets in the “Goldilocks Zone”—the distance from a star where a planet could have liquid water on its surface and enough light to sustain life. But a new study offers a tantalizing possibility that other worlds, far from their host stars, may also be able to support living things, a finding that could dramatically broaden the search for extraterrestrial life.

My Ideal Array Language

2025-07-20 What do I think the ideal array language should look like? The fundamental units of computation available to users today are not the same as they were 20 years ago. When users had at most a few cores on a single CPU, it made complete sense that every program was written with the assumption that it would only run on a single core. Even in a high-performance computing (HPC) context, the default mode of parallelism was (for a long time) the Message Passing Interface (MPI), which is a

Unreal Engine ray tracing stuttering in AMD RDNA 4 GPUs linked to Nvidia-optimized game code

What just happened? Ray tracing was supposed to be faster and smoother on AMD's latest GPUs, yet some demanding games still struggle. A closer look now points to the real reason behind the disappointing performance. It's not just hardware limitations at play – engine choices and driver quirks are also shaping the experience.
