ismtsiout.com

I recently put together ismtsiout.com, a small site inspired by ismtrainierout.com. It scrapes a webcam (provided by northbendweather.com, which is an awesome site) that answers one very specific question: is Mt. Si visible?

Stack information: an Azure Function written in Go scrapes northbendweather.com on the hour during most daylight hours, then hands the image to a cheap Azure OpenAI vision model (at the time of writing, gpt-4.1-mini) to decide whether the mountain’s silhouette is visible. The Function pulls current conditions from the US National Weather Service (no API key necessary), and writes both the photo and the status in a small JSON file to Azure Blob Storage. A vanilla HTML/CSS/JS frontend using Azure Static Web Apps reads status.json and renders the latest image with a bit of clever CSS for the weather-dependent background.
