Part 2 - This post describes the development setup, project structure and contribution process for building and landing a Home Assistant Core integration.

Concurrency For Starlette Apps (e.g FastAPI / FastHTML)
We often want to call LLMs in Starlette based apps (FastHTML, FastAPI, etc.) apps, and we don’t want to block the server on network calls to APIs. This post documents my explorations of various approaches that can run tasks in the background without blocking the main process.

Deploying (Multiple) Django Apps to a Single Server with Kamal 2
Cory Zue describes migrating two Django apps to a shared Hetzner VPS using Kamal 2, detailing the process of setting up a production Dockerfile, creating a Kamal deploy configuration, and addressing challenges with health checks and Django's security settings.
