The Aspire CLI is a cross-platform tool for creating, managing, and running polyglot Aspire projects. This post covers the core commands you’ll use day-to-day.
How I architected a single codebase to seamlessly switch between Azure OpenAI, GitHub Models, Ollama, and Foundry Local without touching the API service
When building my latest .NET Aspire application, I faced a common challenge: how do you develop and test with different AI providers without constantly rewriting your API service? The answer turned out to be surprisingly elegant - a configuration-driven approach that lets you switch between four different AI providers with zero code changes.
Headless CMS Without a PC on GitHub Pages
I’ve been running my site on GitHub Pages - no server, just git and GitHub Actions. But I still want a CMS that works on mobile, without dragging around a laptop or doing a Git clone. Enter Sveltia CMS + Sveltia CMS Auth on Cloudflare Workers. Here’s how to glue it together.
Understanding AI and Prompting Techniques Part 1 # Artificial Intelligence (AI) has rapidly evolved from science fiction to an integral part of our daily lives, transforming how we interact with technology and reshaping industries worldwide. Whether you’re using ChatGPT to draft emails, asking Copilot to write code, or generating images with DALL-E, understanding how to effectively communicate with AI systems has become an essential skill.
In this first part of our series, we’ll explore foundational concepts of AI, machine learning, deep learning, and generative AI, then dive deep into the art of prompting-the key to unlocking AI’s full potential.
This month at Stir Trek 2025, I presented on Dev Containers and GitHub Codespaces, demonstrating how these tools streamline both local and cloud-based development workflows. The session covered the essentials of creating portable development environments, customizing containers with features and extensions, and launching Codespaces directly from your repository. A lively Q&A followed, with attendees asking about strategies for running and working with multiple containers. Below, I’ve distilled those discussions and provided a deeper dive into shared container configurations across multiple projects-including folder structures, Docker Compose setups, VS Code workflows, and advanced tips you can apply in your own work.
Last week, I spoke at the Copenhagen Developers Festival about using GitHub Codespaces for cloud-based development. This is an amazing conference with an incredible lineup. I’ve done this talk plenty of times, sharing how flexible and convenient cloud development environments can be. But this time, things didn’t go as planned.
