We’ve all used HTTP before - we use it every time we go to Google or Facebook, every time we refresh our Twitter client on our phone.

HTTP is a very well defined protocol that we can use to build our own apps. It guarantees a response if you make a request, it has predefined error codes that everyone implements and it’s a very simple format to read if you need to inspect what’s going on by looking at it.

This talk takes you through HTTP, starting at the beginning with how a connection is established, parsed and how the response is formatted. We’ll also cover things like status codes, common headers and some advanced topics such as HTTP streaming and web sockets.

Move over Jenkins, there’s a new kid on the block and it’s called GoCD.

GoCD is a continuous integration system developed by Thoughtworks and open sourced in 2014. At it’s core, it’s a pipeline based build system that takes an input (or multiple inputs) and runs commands that you define on it.

This talk is a basic introduction to application packaging and continuous delivery, along with an overview of GoCD and how it can be used to ship continuously.

Not Invented Here Syndrome is a big problem in a lot of companies that believe that what’s out there isn’t suitable for them. They believe that they can do a better job writing something custom than adapting open source products.

This talk covers a lot of common problems that emerge in day to day development and takes a look at the available solutions that have been adopted by hundreds of companies. From things like logging and metrics to database access, this is a whistle stop tour of all the technologies out there that you could be using today.
