A Powerful New ‘QR Code’ Untangles Math’s Knottiest Knots | Quanta Magazine With a newly discovered mathematical tool, researchers are hoping to gain unprecedented insight into the structure of complex knots.

Mathematicians have built beautiful, snowflake-like codes to untangle some of the trickiest knots. @ericaklarreich.bsky.social reports: www.quantamagazine.org/a-powerful-n...

Surveillance Pricing: Exploiting Information Asymmetries For over a century, fixed prices have made markets more transparent. Surveillance pricing threatens to reverse that progress by allowing corporations to secretly tailor prices using personal data.

After France, Denmark is moving too: its Digitalisation Ministry plans to phase out Microsoft, switching to Linux and LibreOffice in the coming months. The goal is clear—reduce dependence on a handful of global tech giants and strengthen digital sovereignty.

This Isn't Trading. It's Theft from Your Retirement. Someone keeps making perfectly-timed bets right before the President speaks. The victims are your pension, your 401(k), and the country I took an oath to defend.

Fifteen minutes before the President announced he was pausing strikes on Iran, somebody moved $500 million in oil futures. Somebody knew. Somebody told them. Or somebody is them.

Featured Artist: Jess's Lighting Experiments with Noisedeck 2.0 A look inside the creative process behind five new generative pieces that explore Noisedeck 2.0's new lighting effect.

Noise Factor is starting a program to showcase artists making cool stuff with @noisedeck.app . As co-founder, I've made the executive decision to feature myself first. 😂

Here are some fun things I made with noise and the new lighting effect:

WebGPU Node Graph - Ryosuke In this blog I’ll break down the process of writing a node based renderer for WebGPU, what the architecture looks like, and how it practically works.

Interested in how Geometry Nodes work in Blender? In this blog I walk through the process of making a 3D node-based renderer from scratch using #WebGPU and Typescript.

AI doom warnings are getting louder. Are they realistic? Researchers are increasingly sounding the alarm that artificial intelligence could end humanity. But such doomsday warnings carry their own risks.

Good critical analysis of the idea that AI could end humanity by @lizziegibney.bsky.social

Many "warn that raising the alarm unnecessarily could be harmful" by distracting from well-documented risks of AI — such as misinformation and mass surveillance.

The Vercel Breach: OAuth Supply Chain Attack Exposes the Hidden Risk in Platform Environment Variables An OAuth supply chain compromise at Vercel exposed how trusted third party apps and platform environment variables can bypass traditional defenses and amplify blast radius. This article examines the attack chain, underlying design tradeoffs, and what it reveals about modern PaaS and software supply chain risk.

It's not just one thing — it's another thing | TechCrunch This sentence construction ("It's not just this — it's that") has become so common in AI-generated writing that it's no longer just a clue that a piece of writing may be synthetic — it's almost a guar...

The biggest tell that you’re reading AI-generated writing these days isn’t em dashes but instead the “it’s not X, it’s Y” sentence structure.

Whenever I spot it, my first instinct is to wonder if the author even read the document or if I’m the first human to read their ChatGPT-authored masterpiece?

The Beauty of Bonsai Styles The way in which a tree grows is often determined by their environment, and as a bonsai artist, I look to honor that environment, and the way in which that tree would grow in nature, when determining how to shape and style a bonsai.

Horizontal bar chart comparing agentic coding reliability across three groups. Frontier models (Claude Sonnet 4.5, Gemini Pro 3.1, GPT 4.1) score 80-100% correct. Four-months-ago's local models (Qwen 3 14B, GPT OSS 20B, Mistral 3.1 24B) all score 0%. Today's local models (Gemma 4 26B-A4B, Qwen 3.5 35B-A3B) both score 90%.

A few months ago, any LLM that I could run on my Macbook scored 0% on an agentic coding eval I put together. This month's Qwen 3.5 and Gemma 4 releases both scored 90%.

Globe showing the Atlantic Ocean with arrows depicting the AMOC circulation: warm surface currents (pink/red) flowing northward from the tropics toward the Arctic, and cold deep return currents (blue/purple) flowing southward. The background shows sea surface temperature trends, with a prominent blue cold patch, the "cold blob", south of Greenland, contrasting with warming (orange/red) across the rest of the ocean.

1/ There's a system of ocean currents in the Atlantic that shapes Europe's #climate, drives monsoons, and keeps sea levels stable along the US coast.

In the last 5 years, the scientific evidence that it could collapse has shifted dramatically.
