Is there a way to retrieve a sketch from the Arduino UNO

I lost all my sketches that I had written. But there remains one on my Arduino UNO. Is there a way to retrieve that sketch back to my PC so I may continue building it?

Nope. How's your memory?

So did you learn anything in the process? How did you lose the sketches (which is another way of saying, did you just forget where you put them) and on that basis, what steps are you taking to prevent this happening again?

You can retrieve the binary using avrdude - but it is the binary, the compiled version. What CrossRoads is pointing out is that there is no way that you can recover the source code from that.
