CloudFlared is the application you run on your server, and CloudFlare tunnels are what it connects with. You get the same outcome as a ddns but it functions differently under the hood. You also need a domain name for this I think.

DuckDNS might be a good option to start out with.

Slashdot still gets the job done for tech and science news.

Somewhat related is the concept of ontological shock. Most recently saw a post on Reddit about it, linked below. I can relate to the idea of my brain building a running narrative of how the world works, and fitting information into that framework on the fly. When I come across things that don’t fit into that framework it’s easy to dismiss the information and run towards people that share that worldview. Ontological shock happens when you reexamine the core of your worldview based on irrefutable new information, and realize that your existing framework of predicting and understanding things in the world no longer works. Facsinating stuff, and it truly shows that we can absolutely be living in completely different realities than our neighbours.
