To survive, every software needs to change over time. However, if the changes are too steep, the survival might quickly turn into a demise. Today we talk with our own Scott Ford, co-founder of Corgibytes and co-host of the Legacy Code Rocks, about Lehman's laws - a set of principles that explain the forces which push software systems to change and the forces that restrain that change.  Hear from Scott how Lehman's laws can help you in your work and get to know Scott a little bit better.
