New Book on QuickCheck

Posted on by

Hi Everyone

I just wanted to let everyone who may be following the blog know that I have published a new book on using QuickCheck with Erlang. If you have heard about QuickCheck, or PropEr or property based testing in general, and didn’t know where to get started then this is the book for you. It starts with very basic “Hello World” type tests, and then moves up to generating data, testing stateful systems, Property Based Test Patterns and will even include bonus chapters on how to generate HTML and how to do TDD with quickcheck

052 – Erlang in Anger

Posted on by

Ever have a system go strange on you, or fall down under load? Erlang has some amazing tools to try and debug these cases. Regular panelist Fred joins us to talk about his new book “Erlang in Anger” and his recon library. With these you will be in good shape to debug a system in production without breaking it more.

Erlang comes with its own datastores ETS and Mnesia. These store Erlang terms directly so you don’t have to map your data into SQL types. They can also be used to create databases in Memory or on disk or both, this can lead to blindingly fast distrubted systems

We speak to Claus about how Mnesia was created and why. We also talk about when it is a good fit to use Mnesia for data storage and when it would not be.

If you are considering what data storage engine to use for your next project listen to this first.

049 Supervisors

Posted on by

Supervisors are all about creating solid guarantees of how the system will recover after a fault and how it will be setup. If Erlang supervisors have ever confused you, or if you want to understand how this feature makes erlang one of the most powerful tools for building distributed systems this is the episode for you

“…when 100 people are listening to you for an hour, that’s 100 hours of people’s time devoted to what you have to say. If you can’t spend 5 or 10 hours preparing for them, thinking about them, and refining your points to best suit their needs, what does that say about your respect for your audience’s time? It says that your 5 hours are more important than 100 of theirs, which requires an ego larger than the entire solar system. And there is no doubt this disrespect will be obvious once you are on the stage.” – Confessions of a Public Speaker , Scott Berkun

Conferences, we talk about them almost every episode, but what are they like, how do you go to your first conference? How do you become a speaker at one and how can we make our conferences better? We talk at length about all of these things with a great crew of old timers and new folks
