A look at the brokers buying unused AI credits from startups and reselling them — the marketplaces, the bulk-discount routers, and the message boards where off-market inference changes hands

Saint Lucie Nuclear Power Plant Unit 1 was manually shut down Aug. 13 after 3 control rods dropped into the core. The NRC classified it as a non-emergency.

MathCode is a terminal AI coding agent with a built-in math formalization engine: describe a problem in plain language and it converts it into a Lean 4 theorem and attempts a formal proof.

A new book, “Little Blue Dot,” by Katherine Dunn, raises questions about the unintended consequences of knowing where we are, Shayla Love writes.

Your agent re-solves yesterday's problem because nothing wrote it down. The fix isn't a platform you adopt — it's one command, a folder you own, and a loop that closes on your own disk. And when a team needs the same lore, it's a free account, one install with your key, and one command to bring everything you've already learned along.

New research has uncovered how a London estate agent used immersive cosmorama displays to give wealthy buyers a Victorian-era virtual preview of luxury homes decades before photography or the internet.

Just a few miles from the tallest concrete dam east of the Mississippi River, there's a paved road that ends at a mysterious tunnel. This unfinished roadway, deep inside the Great Smoky Mountains National Park, is known as the Road to Nowhere.

This creates a defining product-design challenge: inventing how people and teams work with AI that does real work, not merely chats. We're looking for a Head of Design Engineering to own that experience holistically—making the entire product simple, intuitive, and beautiful, then personally implementing most of it in production.

One AI with one memory that everybody shares. Say something to it. It answers what catches it, and it remembers what you did to it.

George Hotz's comma.ai eGPU dock ships with open-source ASM2464PD firmware: $249 for the dock, $799 with a Radeon RX 9060, and it works on a normal PC.

In 1926, Henry Ford gave his employees both Saturdays and Sundays off – and the two-day chunk of time to party, pray or simply do nothing was born. Now it’s changed beyond recognition

A few hours ago I switched my nameservers to Cloudflare in order to enable R2 bucket serving through my own subdomain, and I found out that it silently had injected a JS analytics snippet in my HTML-only JS-free site textlog.cc — I had to go to the Analytics dashboard, Add the site to the analytics and <i>then</i> disable the snippet. I find this approach entirely invasive, you should opt-in to features like that not have to opt-out. Just a warning out there to folks who might not be aware of this.

Atomically thin van der Waals crystals epitomize ideal material systems in the two-dimensional (2D) limit. This reduction in dimensionality often leads to important consequences, best exemplified by the emergence of new physics in graphene and other 2D materials that can be readily tuned by gating1,2. Vast opportunities arise in extending this top-down approach to other material systems. Recent experiments have demonstrated that the essential physics of high-temperature superconductivity in cuprates is contained within just two CuO2 planes3. Here we push dimensionality reduction to the extreme by examining a single layer of Bi2Sr2CuO6+δ (Bi-2201), which comprises only one CuO2 plane. In this ultimate 2D limit, we observe a robust dimensionality effect that manifests as an approximately 10% reduction in the optimal superconducting transition temperature. Moreover, this reduction in dimensionality offers unprecedented tunability—we successfully extended the phase diagram of Bi-2201 into uncharted territories via finely controlled oxygenation of single-monolayer specimens. Leveraging this tunability, we discovered that an anomalous metal state emerges between the insulating and superconducting states as the temperature approaches zero. Concurrently, we observe an anomalous scaling behaviour characterized by a divergent critical exponent. These findings illuminate the nature of the superconductor-to-insulator quantum phase transition in cuprates. A high-quality, pristine monolayer cuprate superconductor with a single CuO2 plane is fabricated and used to identify two quantum critical phenomena emerging between the Mott insulating phase and the superconducting phase.

This question---what we should tell students to do with AI---is a good trigger to think about what we ourselves should be doing (which is what this essay is really about).

Starting with v2.0, scheduled for fall 2026, DuckDB will support asynchronous reads of Parquet and CSV files. This can significantly speed up queries when synchronous I/O does not saturate the available bandwidth, as is typical in EC2/S3 compute-storage setups.

Almost every notable managed Postgres provider bundles a connection pooler, giving us a strong hint that connection management is a product problem rather than a user problem.
