Running AI Agents on Cloudflare: Workers, Workflows, and Durable Objects

Bernstein v1.8.4 ships with Cloudflare cloud execution. Agents can now run on Workers, multi-step tasks use Durable Workflows, artifacts go to R2, and state persists in D1. Here's the architecture and how to deploy. Why local-only limits adoption Running agents locally works for individual developers, but it has real constraints. Your laptop is the bottleneck: CPU, memory, and network ...

🧪 From Idea to System: A Simple OpenClaw Prototype

To make this real, I built a minimal version of OpenClaw’s core idea: Turn a raw human intent into a structured execution plan. Not a full product. Just the core intelligence loop. 🧠 Core Concept The system has one job: INPUT (intent) ↓ AI decomposition ↓ structured execution plan ↓ action-ready output No chat history. No conversation fluff. Just transformation. 🧱** System Architec...

Generative UI with LLMs: making web pages adapt to each user

Most web apps show the same layout to every user. Large language models (LLMs) change this: they let you generate adaptive, per-user interfaces that restructure themselves based on what each person cares about. TL;DR Web pages look the same for every user, but LLMs can adapt them per user or per cohort. The LLM generates a template once — not on every page render. Cost stays bounded. ...

Fully Automated Website Day 16: Cottonburr Mortar — Rootline Defense's First Arc-Trajectory Plant

Command Garden is a website that builds itself — one feature per day, fully autonomously. No human writes the code. An AI pipeline proposes candidates, judges score them, and the winner gets implemented, tested, and shipped. What shipped Cottonburr Mortar is a new plant that lobs splash shots over the front line and lands on the enemy farthest back. Today's Over the Top challenge pulls...

Proven WHOIS Privacy Protection for Anonymous Domains

Originally published at https://monstadomains.com/blog/whois-privacy-protection/ Every domain you register creates a public record that most people never think about until it is too late. WHOIS privacy protection is not an optional upgrade for the privacy-obsessed – it is the baseline requirement for anyone who does not want their home address, phone number, and registrant email published in a ...

How Adversarial Judge Pipelines Make AI Agents Trustworthy

An AI agent writes code that gets committed to your repository. Another agent extracts financial data from PDFs and feeds it into a report your CFO reads. A third agent responds to customer support tickets at 3am. None of them have a quality gate. The agent ran. It produced output. That output went somewhere. If it was wrong — hallucinated, incomplete, subtly broken — you find out when a custome...

I Tried to Run VGG19 on a CPU… It Failed. So I Fixed It."

"Turning a 500MB deep learning model into something actually usable using pruning, quantization, and simple tricks" Deep learning models look impressive when you read about them. High accuracy, benchmark scores, state-of-the-art results. But the moment you try to actually use one in a real system, things feel very different. That’s exactly what happened when I started working with VGG19. ...

Hunting Disk Hogs on Ubuntu: A Shell Script for Finding the Largest Files

Why this script exists If you've ever watched your free disk space quietly shrink over a few weeks of active development, you know the feeling: yesterday you had plenty of headroom, today your IDE is yelling about low disk space, and you have no idea what ate the difference. Active Node.js and Python projects are especially good at this — node_modules, build caches, .next directories, v...

Turbo Frames don’t update the URL… unless you do this

Want to try it yourself? A full working demo is here: turbo-advance-vs-replace. Clone it, run bin/setup and follow DEMO.md for more tips. Turbo Frames are one of the best things about Hotwire. Wrap a part of your page in <turbo-frame>, and navigations inside it become fast partial updates instead of full page reloads. No JavaScript, no API endpoints, just HTML. But by default frame navig...

12 Topology Patterns for Multi-Agent Systems

Most frameworks give you one topology. We built twelve. When engineers build multi-agent systems, they typically default to a single execution pattern: chain agents together sequentially and call it a day. But agent orchestration is a graph problem, and different tasks demand fundamentally different graph shapes. A code review pipeline has different execution semantics than a debate between reaso...

Why Every AI Team Needs an Agent OS

Let me describe a scenario you've probably lived through. Your team builds a multi-agent system. It works in development. You demo it. Leadership is excited. Then someone asks: "How do we run this in production?" Silence. Because running agents isn't the hard part anymore. Operating agents is. The infrastructure gap nobody talks about Agent frameworks have matured remarkably. CrewAI...

How are you protecting yourself against the imminent AI dooms zero day?

Above all this is a fun discussion. Don't get too serious :) As LLMs get better and better at pattern matching against vulnerabilities, and gaining better logical inference, it's a matter of time until a human or a group of humans and an LLM(s) find a plethora of zero days, some possibly unpatchable. I'm sure others have thought the same, so I'm curious just what the general zeitgeist is. I perso...
