A week in Xbox VR with Microsoft and Meta’s new $399 headset

is a senior editor and author of Notepad , who has been covering all things Microsoft, PC, and tech for over 20 years. Microsoft and Meta announced an Xbox-branded Quest VR headset last year, and it’s going on sale today for $399.99. The Meta Quest 3S Xbox Edition is a custom colorway VR headset that comes bundled with an Xbox wireless controller, matching Touch Plus controllers, and three months of Xbox Game Pass Ultimate. I’ve been using the Quest 3S Xbox Edition over the past week, and I wa

The Morning After: Samsung’s big foldable Unpacked event takes place on July 9

The third Unpacked of 2025 (following installments in January and May) will be on July 9 at 10AM ET, kicking off in Brooklyn, New York. The company usually debuts its latest foldables in the summer, so we’re expecting to see the Galaxy Z Fold 7 and Flip 7 here. However, there’s an extra wrinkle (don’t say wrinkle with foldables!): It’s looking like the premium Galaxy Z Fold Ultra is joining the family. What exactly can you expect? We've written all about it. When it comes to foldables, one rece

A Chinese firm has just launched a constantly changing set of AI benchmarks

Development of the benchmark at HongShan began in 2022, following ChatGPT’s breakout success, as an internal tool for assessing which models are worth investing in. Since then, led by partner Gong Yuan, the team has steadily expanded the system, bringing in outside researchers and professionals to help refine it. As the project grew more sophisticated, they decided to release it to the public. Xbench approached the problem with two different systems. One is similar to traditional benchmarking:

I was surprised by how simple an allocator is

Table of Contents Introduction Recently I was looking at an issue on mimalloc, a "state-of-the-art" memory allocator developed by Microsoft. The issue was quite simple, developers wanted a way to preallocate a piece of memory and use it as mimalloc's heap. Seeing that mimalloc does not offer this feature, I thought: "how hard can it be to write a memory allocator to manage a preallocated region?". The answer to this question is: "given enough time, even a monkey with a typewriter can write

Xbox's VR headset with Meta could be released sooner than we thought

Xbox has come a long way since its humble beginnings as a chunky console. It's recently taken on the form of an Asus gaming handheld, and it might even be packaged as a VR headset soon. According to an image leaked on X and Game Sandwich, Xbox is reportedly teaming up with Meta to release an Xbox-branded Quest 3S headset in the coming days. The rumored specs show a very similar build to the base model Quest 3S with 128GB of storage, but will reportedly be bundled with an Xbox wireless controller

Think of a Number

My feed was recently clogged up with news articles reporting that Sam Altman thinks that AGI is here, or will be here next year, or whatever. I will refrain from giving even more air to this nonsense by linking to the stories. This kind of irresponsible hype-generation drives me nuts (although it also drives up stock prices so I can see why the tech bros are motivated to do it). Sure AI can have a good crack at undergraduate mathematics right now, and sure that’s pretty amazing. But our universi

No Hello

Note that Keith could have got his answer minutes sooner, and needn't have kept Tim waiting. In fact, Tim could have started thinking about the question right away! People who do this are generally trying to be polite by not jumping right into the request, like one would in person or on the phone - and that's great! But it's 2022 and chat is neither of those things. For most people, typing is much slower than talking. So despite best intentions, you're actually just making the other person wait

Getting free internet on a cruise, saving $170

Internet on a cruise ship is insanely expensive, but a little bit of DevTools knowledge and some simple Python scripting can go a long way when it comes to getting free internet Picture this, you’re a teenager in the middle of the ocean on a cruise ship. All is good, except you’re lacking your lifeblood: internet. You could pay $170 for seven days of throttled internet on a single device, and perhaps split it via a travel router or hotspot, but that still seems less than ideal. I’ve been trave

Chemical knowledge and reasoning of large language models vs. chemist expertise

Benchmark corpus To compile our benchmark corpus, we utilized a broad list of sources (Methods), ranging from completely novel, manually crafted questions over university exams to semi-automatically generated questions based on curated subsets of data in chemical databases. For quality assurance, all questions have been reviewed by at least two scientists in addition to the original curator and automated checks. Importantly, our large pool of questions encompasses a wide range of topics and que
