We're opening the new year on a technical note with Simon Davy from Canonical reflecting on his experiences using feature toggles within a release strategy and Phil Rice is back to to cover Constraint Driven Development. Hopefully recovered and recharged after the festive season we've all managed to settled back into the sustainable pace that was present before the festivities started. If not Agile Yorkshire is here to help inspire your start to 2014.

Eventbrite - January Agile Yorkshire Meetup

Simon Davy on Feature Flags in Production
A retrospective on 2 years of using feature flags to control users exposure to changes. Will cover the nature of feature flags and our motivations for using them, as well as problems encountered and challenges we had in managing them. Will provide some specific examples in a python Django application using the Disqus' Gargoyle library.

Phil Rice and Constraint Driven Development
Constraint Driven Development or CDD is an extension of Behaviour Driven Development and Test Driven Development.  
CDD is programming style that specifies computational problems using tests and then giving small fragments of code that satisfy that particular test. The CDD library is responsible for delivering a fully working tested system from these fragments
This talk will look at an open source Scala CDD library and show how it can be used to solve problems.
