I remember having a Spirograph as a kid and being obsessed with it. Its geometric patterns are hypnotic and gorgeous. I also love generative music composition. So bringing those two things together in a browser tab, I'm hooked. Musical Spirograph is a relatively simple concept. A set of points dash around the screen according to […]

OpenAI is calling for California to strengthen SB 53, an AI safety bill that the company previously opposed.

Built by DeepMind alumni, British AI lab Inherent released Faraday, an AI agent whose ability to replicate scientific papers could be a stepping stone for innovation.

Writing an MCP server is the easy part. Shipping one as a Claude connector means passing four gates that have nothing to do with your business logic: Anthropic's network can reach you, Claude can get an OAuth client identity, a human reviewer approves your tool design, and your server does not waste the user's context window. Here is the checklist I wish I had had, in the order the failures actually happen. Gate 1 — Can Anthropic's infrastructure reach you? Claude connects fro...

The .NET 10 JSON console logging change is small enough to miss during an upgrade: the formatted message still exists, but a typical record no longer duplicates it at State.Message . A collector, script, or snapshot test that reads only that nested property can start returning null while the application continues logging normally. I treat console JSON as a schema whenever another process parses it. That means a runtime upgrade deserves a contract test, not just a visual check in a terminal...

I built Feedvote because I kept running into a simple product problem: our team wanted to keep planning in Linear, but customers and stakeholders needed a much narrower view of what was happening. Giving every customer a Linear seat was the wrong boundary. It exposed an internal workspace, added account friction, and made it too easy to share implementation details that were never meant to be customer-facing. So I treated the customer roadmap as a controlled projection of Linear , not as ...

In release 4.0, the Ruby Powers-That-Be have brought class Pathname into the Ruby core. This is a Very Good Thing. Through its many instance methods, a Pathname object provides a consistent and convenient interface to numerous methods in other classes and modules: Wraps almost all methods in class File and module FileTest . Wraps some methods in class Dir and module FileUtils . Advantages of using Pathname instead of these others: You don’t have to know which clas...

WordPress is often treated as a traditional CMS, but its REST API makes it possible to use WordPress as the backend for applications, dashboards, mobile clients, automation systems, and external services. The difficult part isn't registering an endpoint. The difficult part is designing the endpoint so that authentication, authorization, validation, error handling, and data access are all handled correctly. A production API needs a contract. It needs to know: Who can access it ...

I am running an AI-native startup. Early on though, I would spend so much time staying ahead of every new AI hot take that I lost focus on what I needed to do to move the company forward. I didn't need a hundred skills, fifty MCP servers, or Ralph Wiggum loops sending my API bill to the moon. I needed answers to plain questions. What is this model costing me? Is it writing code I keep? Is that tip I saw on X helping, or just making me feel busy? Those are operating questions. Using Claude is ...

“We do not store it” is one of those software sentences that sounds complete until you ask one rude follow-up question: Who is “we”? Your app may send a user’s text to an AI provider, copy it into an error log, forward part of it to a tool, save the result in a database, and leave the original in an analytics event. The model provider can retain nothing while your product quietly collects five other copies like a squirrel preparing for winter. That is why a retention setting is useful...

Building an AI feature is easy. Building a reliable multi-agent pipeline that coordinates four specialized AI agents, persists intermediate state, skips already-completed work on retries, and keeps the API responsive while the models think — that is the hard part. This post walks through the architecture behind Clause AI , a platform that analyzes rental and lease agreements. It extracts key terms, flags risky clauses, and lets users chat with their contracts using RAG (Retrieval-Augmented...

Managing short-term rentals and homestays usually involves a chaotic mix of spreadsheets, WhatsApp messages, and scattered paper receipts. Propio was built to replace that chaos with a purpose-built financial tracking platform. One of the most powerful features in Propio is Smart Scan — an AI-powered OCR system that allows property managers to drop a receipt, invoice, or booking confirmation into the app and have all the relevant financial fields extracted and categorized automatically....

Retrieval-Augmented Generation (RAG) is often described as a simple pipeline: Query → Retrieve documents → Send context to an LLM → Generate answer In production, however, retrieval is rarely that simple. The retriever can return irrelevant documents. Important information may be buried in the middle of a document. A query may be too vague for semantic search. Retrieved chunks may lose their surrounding context. And sometimes the model does not need retrieval at all. The quality ...

Sprix AI has released SAGE Router, a public research prototype that chooses whether an agent should keep working, recruit collaborators, or hand a task to another agent. The consequence is less glamorous but more useful than another agent-discovery layer: it treats multi-agent routing as a decision that must account for work already completed, the cost of moving context, and the dependencies still blocking a task. The repository calls this State-Aware Graph Exchange, or SAGE. It sits above th...

Everyone seems to be building AI agents. Give a model some instructions, connect a few tools, add a system prompt, and suddenly we have an "agent." Except there's a problem. A lot of them aren't particularly useful. When an agent produces a poor answer, the immediate assumption is often that the model isn't capable enough. But sometimes the model isn't the problem at all. The agent simply doesn't have the right knowledge to work with. That's where things get interesting. The...

This is an intriguing demonstration of terminal graphics capabilities, and has a strong retro Street Fighter feeling. Comments

While studying Geometric Algebra I have built some interactive visualization to demonstrate how geometric transformations (rotation, scaling, translation) can be constructed by just composing reflections. Accepting reflection as the most elementary geometric operation was an eye opening moment for me. I think some of you might enjoy the interactive visuals.
