    Legacy Management and Legacy Code

    Posted on July 29th, 2017.

    I just left a meeting where I said some disillusioned things about management’s lack of interest and drive to understand their part in agile development. Why don’t we treat legacy management like we treat legacy code? Legacy code is considered legacy partly because we know it won’t come cheap to change it even if we wanted to. Instead we...

    Introducing Scaffolding Tests

    Posted on December 1st, 2016.

For your basic web app it might be a test that calls a method in some kind of web controller class and asserts that that call results in a specific value being written to a database from a...

    An Explicit Meta Solution Domain

    Posted on February 16th, 2016.

    When writing code, we try to implement a model of a certain real life domain. In a basic OO approach, we let nouns from this problem domain give name to our classes, while verbs give names to the classes’ methods. Our code is the solution domain. In addition to the problem domain and the solution domain I like to think that we actually...
