This is a quick tutorial explaining how to get a static website hosted on Heroku.

Why do this?

Heroku hosts apps on the internet, not static websites. To get it to run your static portfolio, personal blog, etc., you need to trick Heroku into thinking your website is a PHP app. This 6-step tutorial will teach you how.

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

Raspberry Pi, Static HTTPS site with Docker and Nginx

This tutorial is dated Oct 2021, if it's much further on than that this information might be out of date.

This is a guide on setting up a static HTTPS website on your raspberry pi using docker and nginx. The aim is to have this running on the raspberry pi and to be able to access it from a host computer on the same local network. You should already be able to ssh into your pi from your host computer and have raspberry pi OS set up.
