RUN NEMOCLAW WITHOUT KILLING PORT 8080 ;)

Struggling with NemoClaw's hardcoded port 8080 blocking your setup? Just skip NemoClaw and run OpenShell directly. NemoClaw is only a management wrapper on top of OpenShell. The actual sandboxing, network policy enforcement, and agent security all come from OpenShell itself. Here is all you need: https://docs.nvidia.com/openshell/latest/index.html Start the OpenShell gateway on a port of your ...

How I Run a Team of AI Coding Agents in Parallel

Running one AI coding agent is productive. Running five in parallel is chaos. I've been using Claude Code daily for months. It's great — until you realize there are four other tasks sitting idle while you wait for one agent to finish refactoring a module.

Containers written as HOCs? (in the Container/Presentational pattern)

I keep seeing the Container/Presentational pattern when looking for ways to structure react components. I love the idea of separation of concerns and separating out the data from the view, but then every time I look at a container, at the end it calls one specific presentation, which for me, seems to be limiting the reusability of the container. I'm a little confused why I can't find anything that...

What I Learned Automating Software Development (After 20 Years of Doing It Manually)

In Part 1, I told the story of building OpenLoop — an open-source feedback platform — by emailing an AI agent for 5 days. 160+ emails, $15 in tokens, zero lines of human-written code, and a working product at the end. Now let's talk about what I actually learned. What the AI Was Good At Let's start with the positive, because there's plenty of it. Scaffolding speed is unreal. Within...

Stop Installing CLI Tools: 7 Data Format Conversions You Can Do in the Browser

Every developer has been there. You need to quickly convert an IP address to hex, escape a JSON string, or turn some text into a CSV file. Your options? Install yet another npm package, find a shady website that uploads your data to a server, or write a one-off script. What if you could do all of that directly in your browser, with zero data leaving your machine? I built a collection of browser-...
