I want a bot that can repeatedly refresh a specific URL until it detects a specific text phrase, at which point it beeps (preferable), flashes, or otherwise alerts me.
So if for instance there's a thread about breakfast food, I can leave it refreshing every few seconds/minutes until someone later mentions delicious waffles, at which point I hear the beep while in the kitchen eating waffles and rush in to quote him and say "OMG I LUV WAFFLES!!!1 BLUEBERY OR STRWBERY?!?"
Naturally, the real application will be considerably more practical, but the concept is the same.
It seems like an awfully simple concept but I can't for the life of me figure what I'm looking for. Any help?
