update

Hello,

There is a website (very simple) which will be updated soon and I'd like to receive an alert at the moment it changes (like a sound, a popup,...)

I guess I should send request every x minutes and compare the result with what's now but I don't know how to do that.

I don't really care about the language used, I know java, python, php, a bit of c and bash (I'm on linux)...

Thank you
