i dont leave my bike outside for long when I am not there, but I use a Ulock, i lock the frame and front wheel always to a parking meter (its hard for people to get away with removing a parking meter). I have also made my bike look really crappy with stickers and painters tape and tubes all over it. I feel like a theif is less likely to take a bike that someone may recognize right away since it doesnt look like every other "off the rack" bike. It will also be more difficult for them to sell if its all messed up looking, so they may not bother. I think common sense is your best protection, if someone wants your bike, they are going to get it.... keep it in a well lit area, lock down anything expensive and keep your bike looking as sh1tty as possible.
