If you read the Cloudflare Tunnel post, you know the problem: localhost does not accept webhooks, OAuth providers reject http://localhost as a redirect URI, and showing a client a work-in-progress means a deploy. Cloudflare Tunnel solves it, but it wants a Cloudflare account and domain setup.

Expose localhost with a stable custom subdomain using Cloudflare Tunnel — a free ngrok alternative that works behind NAT and corporate firewalls, with no session limits.

A production-quality .NET Aspire demo — five microservices, PostgreSQL, Redis, and RabbitMQ, all orchestrated from a single C# AppHost file.

The first time I let Copilot loose on one of my Angular repos, it wrote a perfectly reasonable component for 2021: constructor injection, class properties for state, NgModule imports. We were on Angular 19 with signals and standalone components.

My first serious Codespaces session was a demo I nearly cancelled. I wanted to show my mean-docker starter (Angular, Express, MongoDB, everything in Docker Compose) to someone whose laptop had none of that installed. No Node, no Docker Desktop, no MongoDB. Instead of walking them through an afternoon of setup, I clicked “Create codespace” on the repo and had the full stack running in a browser tab a few minutes later.

In the previous article I built a custom nginx image and pushed it to Docker Hub by hand: build, tag, login, push. That works exactly once. The second time you forget the tag, the third time a teammate pushes from a laptop with a stale base image, and soon nobody can say which commit produced the image running in production. The fix is boring and reliable: let GitHub Actions do the build and push on every commit to master.
