The "What are FPGAs" webpage has a few typos regarding the words "loose" and "lose": http://www.fpga4fun.com/FPGAinfo1.html.
"Loose" means to intentionally let something go, eg: "Do not loose that flock of deranged geese", or "Loose your arrows into the enemy."
"Lose" means you can't find something, or you no longer have something, eg: "You will lose your pencil", or "FPGAs lose their functionality when the power goes away (like RAM in a computer that loses its content)."
I don't mean to be condescending nor a grammar nazi, but this website will look much better if it uses proper English grammar (as would any website).
That being said, thanks this great website!
