  • This event will be broken down into 2 talks, "How to parse a file" and "Kotlin for the curious" both being presented by Matt Ellis.

    **How to parse a file**

    Yes, we're going to look at file parsing. Sounds a bit boring, right? Wrong.

    In this talk, just for fun, we'll find out how to parse a file. We'll look at simple, handcrafted parsers. We'll finally figure out just how lex and yacc work. And we'll pick apart structured parsers that build abstract syntax trees as you type - ReSharper style. How is an IDEs parser different to a compiler? How do you handle sensible error recovery? What about significant whitespace?

    Everything you always wanted to know about parsing a file, but were too afraid to ask.

    **Kotlin for the curious**

    Interested in Kotlin? And why not - it’s a pragmatic language designed to remove ceremony, solve real world problems and still feel familiar to newcomers. It can target the JVM, Android, JavaScript and native code, even running on iOS. That’s a lot of reach...

    **HTTP API patterns**

    I GET how to DELETE but the real question is "To PUT or to POST?" or is it PATCH? What there's more?!

    After doing the standard HTTP CRUD, sometimes you need to do more, become a little more sophisticated in your manipulation of resources and add some depth to your HTTP API.

    This talk will take you through some common HTTP API patterns, provide you with names for these patterns so we can talk about them, describe what the patterns are and when they are generally used, and go through working examples.

    Hopefully, this information will help people create richer HTTP APIs, make you REST easy and everything 200 OK.

  • This event will be broken down into 2 talks, Advanced Entity Framework Techniques and Reasonable Software being presented by Andrew Gunn and Ian Johnson.

    *Advanced Entity Framework Techniques*


    *Reasonable Software*

    In a reasonable a system (i.e. a system that helps me to understand it, to reason about it) I should be able to understand how to make a change without holding the entire system in my head. I should be able to reason where the change needs to be made and reason about the impact it will have.

    I want to explore what reasonable means to me, from the processes of the team all the way down to an individual block of code. Along the way, we will encounter existing frameworks, tools, and patterns that our community has developed over the years to help us to reason about our code and processes; I feel that they have often been misused and end up creating the opposite effect, adding unnecessary complexity to how we work.

  • Following our continued success of the lightning talks, we are hosting another round! We will be having 6 speakers doing a 10-15 minute lightning talks, if you would like to get involved please message me on meetup or twitter.

    A lightning talk is a very short presentation lasting only a few minutes, given at a conference or similar forum. Several lightning talks will usually be delivered by different speakers in a single session, sometimes called a data blitz.
