Working with legacy code remains difficult. We feel afraid to change it, but sometimes we have no choice.
Learn key techniques to help you manage your risk. J. B. Rainsberger gives you a safe code base in which to experiment and his video demonstrations guide you through the confusing risk/reward decisions involved in living with legacy code. You will learn and practise several specific, safe techniques that you can start using on your own legacy code once you return to your project.
You should purchase this course if you have code that seems impossible to change, code that you feel really uncomfortable changing, or you want to avoid creating code like it in the future. J. B.'s advice transcends business domains and programming languages. Moreover, you get to watch him think through the tough choices as well as improve the design with (relative) grace and ease.
After watching a video, it's your turn to try the techniques out for yourself, and you can even ask your fellow learners for their advice. All you need is a working development environment for your favorite programming language and to install git. (Strictly speaking, you don't even need to do that, but you probably should.)
You don't need to know any fancy frameworks. (That's probably part of what got you into trouble in the first place.) You don't even need testing libraries, although you really should probably find one and install it. You only need a place to watch, listen, practise, and enjoy.
J. B. (Joe) Rainsberger is one of the "second wave" of TDD practitioners: he learned directly from the pioneers of the field. His book, JUnit Recipes, was the standard for over a decade for Java programmers who wanted to do what we today call developer testing or programmer testing. He has taught thousands of programmers around the world to bring high discipline to their work for well over a decade.
Not "just a programmer", J. B. has taught people how to manage the never-ending onslaught of work, figure out how to adopt new working practices chaos-free, understand and even grow to respect their most annoying co-workers, find the time and energy to improve as though finding loose change in the couch cushions, turn their dreary day job into a Dream Job–even how he enjoyed his first retirement from age 34 to 40! Software, life. Agile, not Agile. He's up for anything.

Frequently Asked Questions
Yes and no. Yes, the videos come from exercises that I typically use when I run a Legacy Code Retreat; however, how many of you have attended LCR and got to pair with me, huh?!
You can think of this course as snapshots of all the best moments from all the Legacy Code Retreats I have ever been to, plus all the ones I will ever go to, in a series of highlight reels, tastefully edited.
That's up to you. I've included some information about how to start rescuing legacy code with confidence at work, but the rest is up to you. If you need my help or want to pair with me, then please ask your manager if the Enterprise plan is right for you.
