Hi

For my own education I am running a server from home on a raspberry Pi. Standard Vanilla. Apache, Mysql, php. I have a static PI address which I point to my Parked URL with GoDaddy and just want to see how far I can go with this set up as far as hits and programming.  

I would like to link to my URL here. But I'm not going to as I would hate to be hacked and my server could attack others.

I am very careful about security. But its a moving target. If you have any security Advice for me that would be great as you guys  need to protect your investments. That means you know your security.

I have a home server, static IP address pointed to a url

What could go wrong..?
