Utrecht.rb Talks & Drinks!

Hi everyone!

Monday the 4th of Februari Utrecht.rb is organizing a bunch of lightning talks, as you all probably know by now. As of now we have two speakers, that means we still have one 15m slot open!

If you're not convinced yet, there will be free drinks and pizza sponsored by Github!

So here's the rundown:


Disavow your gods - Sjoerd Andringa

Every app has its god models; Typically a 200+ LOC ActiveRecord model central to the application's domain, stuffed with responsibilities. Everything interacts with it, and it interacts with everything else. And no matter how much you please them with mixins and what not, your gods will punish you. God models are increasingly hard to maintain, they are hard to test, and their tests are slow.

You may never loose your religion entirely, but there are techniques to keep the number god models to a minimum. In my talk I will show you how to move responsibilities from an ActiveRecord model to focussed, lightweight and easily testable classes using a real life example from our product's codebase."

Go Ruby! - Harm Aarts

Ruby is great. But what ugly beast reared it head? Go ( You can't even redefine NilClass!

Let's take a Ruby look at this language which received so much attention in the last year.

    I'm very much looking forward to telling you about Go in a Ruby perspective. Any questions/topics you'd like me to address?

      i second the 'suitability for web dev' question. any web frameworks already (being) built with it?
