This will be a talk on strategies we have employed to "rescue" legacy code, and how you prevent your system from becoming the Big Ball of Mud. It's not code specific, but it is aimed at developers.

There is an almost inevitable slide into complexity that happens to most code bases. As legacy code is more ubiquitous than green fields development, I believe that we spend too little time figuring out how to get better at maintaining existing systems.

Of course, tools like refactor make the code changes much easier, but this is mostly a talk about a mindset of keeping code clean. It is also an appeal to developers to spend more time on design - more thinking and less typing.

I co-founded my software company 34 years ago, so we have plenty of legacy code! I will share some techniques that have worked well for my teams, in our ongoing effort to stop the slide into the mud!
