OpenAI Model Disproves Erdős Unit-Distance Conjecture in Discrete Geometry

OpenAI has disclosed that an internal model generated a proof disproving the Erdős unit-distance conjecture, a long-standing question in discrete geometry. The result, announced on May 20, 2026, was subsequently checked by external mathematicians and presented with accompanying mathematical commentary. It is a notable, but carefully bounded, example of AI-generated reasoning contributing to fronti...

Explaining Stock Returns with the Fama-French 5 Factor Model

In 2023, the Fama-French 5-factor model could explain only 35% of NVIDIA's weekly return variation. In 2024, it explained 82%. That gap tells you something important: NVIDIA's 2023 surge was driven primarily by a narrative that no systematic factor had yet priced in - the sudden recognition that GPU scarcity would define AI infrastructure for years. By 2024, that insight had diffused into the mark...

From Website URL to Useful AI Support Answers: A Practical Training Workflow

Adding a chat interface to a website is easy. Making it answer company-specific questions reliably is the real engineering and content problem. A support assistant needs more than a capable language model. It needs a controlled set of sources, a retrieval workflow, a testing process, and a clear fallback when the available knowledge is insufficient. This article describes a practical website-to-an...

Things I Wish I Knew Before Studying Computer Science

My name is Bless Kimbi Starting a Computer Science degree, I thought I had a rough idea of what I was signing up for. I was wrong about a lot of it. Here's what I wish someone had told me before day one. 1. Grades don't matter as much as you think projects do I spent way too much energy chasing perfect exam scores early on. What actually opened doors later was having things I'd built: ...

🚀 How AI Is Reshaping Software Development in 2026

There was a time when writing code felt like craftsmanship, defined largely by how quickly you could type, remember syntax, and piece together framework APIs. Developers spent hours configuring build pipelines, hunting down missing semicolons, and copying boilerplate code from Stack Overflow. Then AI coding assistants—and, more recently, autonomous AI agents—began taking over much of the routine ...

No, Claude Didn't 'Go Rogue.' Someone Gave It Root and Wi-Fi.

When an AI agent breaches a real system, the instinct is to ask "what's wrong with the model?" Wrong question. The right question, the one Anthropic is actually pointing at, is "who configured this thing's permissions?" Context This isn't new. It's the oldest story in enterprise security wearing a new hoodie. Over-permissioning and unrestricted egress have been root causes behind breac...

Designing REST APIs That Are Easy to Maintain

Designing REST APIs That Are Easy to Maintain When building my first backend projects, I focused on making the API work. As my projects grew, I realized that working code isn't enough. An API also needs to be easy to understand, extend, and maintain. A well-designed REST API saves time for both developers and users. Small design decisions made early can prevent major refactoring later....

Designing MCP Tools for a 7B Model, Not a 70B One

I built an agentic assistant for battery engineering. A physics-based digital twin runs the actual electrochemical simulation, an LLM orchestrates and explains. Partway through, I ran into a failure that had nothing to do with the physics or the prompt wording. It was about how many tool calls I was asking a 7B model to plan in one go, and it changed how I designed every tool after that. ...

Keyv-Linked npm Worm Poisons Hundreds of Packages, Plants Claude Code and VS Code Hooks

A credential-stealing npm worm that first appeared in keyv@6.0.0 spread beyond the Keyv and Cacheable namespaces into hundreds of packages across multiple organizations on August 4, 2026. SafeDep verified 353 poisoned versions across 79 package names in the npm registry. Its monitoring put the wider footprint at 442 versions across 353 names, while Aikido later reported at least 868 packages

An LLM Attacked a Lab, Then Got Turned Around. That's Not the Scary Part.

A research lab says it got attacked by something built on or around a Chinese LLM, and instead of just blocking it, they flipped it and used it against its own methods. Twelve points on HN. Six comments. That ratio alone tells you something: this is either genuinely niche or genuinely under-explained. Probably both. Context Let's be honest about where we are.

I'm building an AI social media tool. Here's what's free and what isn't.

I ran an agency in Jakarta for a few years. Every client engagement had the same first two weeks: figure out what they should post, build a month of content, set up a calendar, then spend the next 30 days chasing them for approvals and answering the same Instagram DMs over and over. Different client, same two weeks. Every time. So I'm building the thing that does it. It's called bleam. It genera...

Artificial Intelligence has fundamentally changed how we build software. Today, it's possible to generate an entire REST API, a React dashboard, or even a complete SaaS application simply by chatting with an AI assistant. A few prompts later, you have authentication, a database, tests, and deployment scripts in place. This workflow has become known as Vibe Coding*. It's fast, it's fun, and hone...
