Legacy Dependency Kata v2.0

Well, well, well. Look what the samurai dragged in. An updated version of my Legacy Dependency Kata. I’ll have to update the Coding Kata Resources page.

I’m not proud to admit that there even was a v1.0 at the moment. Let me explain.

Just over two years ago, I was experimenting with writing katas, presenting at code conventions, and running a coding dojo. It turns out. I wasn’t super fantastic at any of these things. Nevertheless, I wrote a kata, ran it a few times with the kind folks in my dojo, and proceeded to share it with the delightful folks at Utah Code Camp 2014. Reviews were mixed, but overall I felt good about it.

Fast forward to the present. While planning the lunchtime learning schedule for our recent SAFe Program Increment, there was an opening, and I, ever so graciously, decided to run my Legacy Dependency Kata for folks who may not have had the chance to see it before. Upon thoroughly embarrassing myself with some of the crappiest kata slides in existence (slides even I couldn’t completely fathom), I recognized that my life would be forfeit if folks were forced to do the kata again with the same slides the following day.

I dashed to revise the slides and spent many hours on the task. When I presented the kata on the second day, it was a much more successful attempt. I’d go so far as to call it a version 1.7. I spent some more time and enlisted the advice of the ever-gracious and capable Kaleb Pedersen in finalizing v2.0. The source code is still the same. Legacy code problems from 2 years ago are still very similar to what they are today.

I think the new slides do their job. Could this kata still be better? Without a doubt. Please submit your recommendations in the comments or feel free to yell at me on Twitter. I’m sure I deserve it for something.

Without further adieu, I give you Legacy Dependency Kata Version Two.
