If you have no option but to keep the same job and maintain the same old code base, try moderately working on something at home. I say moderately because you don't want to abandon your family or a balanced life, but it helps you learn new technologies and remain interested in the industry. This way, you can keep the dull job that is paying you but still get to stretch the programming muscles. (Having said that, the dull job might be soul destroying! But it's an option...)
