Many hard problems in programming originate from one single source: not properly distinguishing the representation of data from the way it is interpreted. Have you ever written code that filters `$_GET` for SQL injection attempts? Struggled with timezones? Tried to get escaping right for Javascript in HTML? Detected the character encoding of a string? All are examples of this one problem. In this talk we will look at some examples of the representation-interpretation problem and find the general pattern behind it. We will see how primitive types make it so hard for us to get this right, and how we can use value objects to steer us in the right direction. You’ll start finding many more examples of this pattern and understand them more easily.

One of my favorite talks at the conference. He did a really great job of explain why data is hardly to blame when there are problems in the software we created and tied it all nicely with math and code examples.
Highly recommended if you get the chance to see it!
Easy to follow presentation with concise use of theory transformed into language that makes quite easy to think about it!
