A Crystal Ball to Prioritise Technical Debt in Monoliths or Microservices: Adam Tornhill's Thoughts
At QCon London, Adam Tornhill presented “A Crystal Ball to Prioritise Technical Debt”, and claimed that although the technical debt metaphor has taken the software world with storm, most organizations find it hard to prioritise and repay their technical debt. Key takeaways from the talk included methods to identify ‘hotspots’ of code complexity and churn.

Dead Code Must Be Removed
Dead code needs to be found and removed; leaving dead code in is an obstacle to programmer understanding and action, and there's the risk that the code is awakened which can cause significant problems. Deleting dead code is not a technical problem; it is a problem of mindset and culture.

Refactoring and Code Smells – A Journey Toward Cleaner Code
Refactoring helps to move towards cleaner code that is easier to understand and maintain. It takes practice and experience to recognise code smells: symptoms of bad design which indicate deeper problems in the code. Tools can be helpful to refactor in small steps and prevent breaking the code.

Continuous Deployment at Coolblue
Continuous deployment results in a higher sense of responsibility and better quality of deployments, argues Paul de Raaij, technical pathfinder at Coolblue. Coding standards prevent your code base from becoming a mess, automated inspections are great for tedious and boring checks, and manual checks are great for checking if the logic or use of code actually makes sense.

Using Models in Developing Software for Self-Driving Cars
Models play an important role in developing software for autonomous systems like self-driving cars; they are used to simulate and verify behavior, document the system, and generate code. Jonathan Sprinkle explains how to model software used in autonomous systems, the benefits of modeling, using test data to validate the software that drives a car and techniques for writing reliable code.

Applying Supply Chain Management to Deliver Faster with Higher Quality
Supply chain management can raise the bar with continuous development, argues Joshua Corman, Director of the Cyber Statecraft Initiative and co-founder of Rugged Software. Our dependence on IT and software is growing faster than our ability to secure it, and applying supply chain approaches to software development helps to address complexity which reduces risks and increases quality.
