Will compiled binaries run on other Linux boxes?

I don't have a Linux box at home, so I'd like to use my Raspberry Pi to try out some development on Linux. Will binaries compiled on it run on other, more standard Linux boxes, or will they only run on the Raspberry Pi?

Use raspberry pi 3.5mm jack as line in

Is is possible to use the 3.5 jack on the Raspberry Pi as a line-in? I need to record audio through the Pi and I didn't find anything conclusive about its audio capabilities. Would like to make sure before searching for a sound card.
