I just checked if my router's admin was open to public access by connecting with my public IP. It connected! Oh no! That's embarrassing, I thought. Turns out it was just NAT hairpinning. I can't connect from my mobile network.

This is fantastic. I learned to program back in the 90s using QBasic. It came with DOS and along with it a book very much like this PDF. I read through the whole book, entering every line of code in the examples, changing little pieces of it until I understood how it worked. Such good memories. I'll enjoy reading this. Thank you.
