Even if you don't know what you would use it for, a website, or just a server alone, is something very useful. And fun.
I found myself in need of a website. But not one from a "Create your own website" site. Because it's never your own if you get it from one of those. You either end up with .whatever.com and the end of the URL, or you can bearly change the appearance of the site. You really can't get what you want from one of those.
So, I set off on something I had been planning for a long time. Creating my own, real website.
Step 1: What You Need
You don't need a lot to make a server. But some things make it much easier. Here's a list of things you should have to make it much easier, and then a list of basic list of things.
An Extra Computer To Use as a Server (Preferably a Desktop)
A Computer Other Then The New Server
Internet (Preferably with wires, but wireless works too)
A Brain (Or Another Brain To Help You Out)
For my server, I used an old computer built from parts I trash picked.
For a very over used saying, "One mans trash is another mans treasurer" is very true.
Or in this case, one mans trash is another mans website.
