Episode 171 – Beyond Legacy Code with David Bernstein

Craig is at Agile 2017 in Orlando, Florida and speaks with David Bernstein, author of “Beyond Legacy Code“, and they chat about agile technical practices:

  • Agile does have something to with software development
  • Agile 2017 talk “Create Software Quality
  • The real value of Agile is in the technical practices so we can build iteratively, but still very few people practice them
  • The future is already here, but it is not very well evenly distributed – the same applies to Agile
  • Companies are being consumed by their technical debt and they don’t even recognise it
  • What is always cheaper in the virtual domain is building quality
  • Continuous Integration makes the most painful thing in software development (integration) our greatest asset – this in turn gives us feedback
  • We don’t necessarily know there is a better way to do things – but there is a better way to do things
  • We traditionally think of software as a write once event, but it is write many – users want it changed
  • We think procedurally so object oriented code often ends up being procedural with a class statement wrapped around it
  • Test First Development – very few developers know how to write a good test because they haven’t been taught, it was intended to assist with refactoring
  • Studies show about 10% of people follow the Agile technical practices like XP, and only 10% of those are doing it correctly
  • The mindset of testing is different to the mindset of coding and they are mutually exclusive (in the same way we need editors when writing a book)
  • Refactoring is at two levels because we learn in chunks – we need to do while doing test first as well as in the large
  • The Art of Agile Development” – spend 10% of your time refactoring
  • Communication – say what, why and for whom before how – we think in implementation
  • CLEAN code – cohesive, loosely coupled, encapsulated, assertiveness and non-redundant
  • Need to understand what quality means in software
  • Troy Magennis talk “I love the smell of DATA in the morning (Getting started with Agile Data Science)
