London Ruby User Group:Transformers: Code Blocks In Disguise

Transformers: Code Blocks In Disguise
Aanand Prasad has some Ruby code to show you. It looks a little strange - in fact, it doesn’t even look valid.

Array.run do
  x <- ["first", "second"]
  y <- ["once", "twice"]

  ["#{x} cousin #{y} removed"]
end

What does it do, and how does it do it? If you know what a macro is, or a continuation, or a monad, you might be able to guess. If not, don’t worry - by the end, you’ll probably be as confused as everyone else, including the speaker.

Simon Brown's Enterprise Software Developer

This 4-day practical course is about building software within an enterprise environment in a structured, lightweight and pragmatic way. It covers the complete end-to-end software development process; from planning, gathering requirements and software architecture through to the effective use of source code control, automated unit testing, continuous integration and load testing. Pragmatic enterprise software development is about taking the best bits from traditional and modern approaches, blending them together to form a structured yet lightweight approach to building software that's appropriate to the way that your organisation works. This is what the course is all about. Find out more here.

Gojko Adzic's BDD for Developers

This hands-on BDD workshop will help you get the key skills needed to succeed with behaviour driven development and specification by example. Through simulations and practical exercises, you will apply the ideas and practices of BDD to solve the most common issues development teams have with specifications and tests. You will use Cucumber to define and automate BDD scenarios to provide stakeholders with visibility into software features and help the delivery teams drive development and build quality in from the start.
