But, legend has it that there was one obstacle that even he couldn't overcome: a towering wall of ice, grown by locals across a mountain pass. M Jackson explores the ancient methods of growing glaciers and how they can be used to combat climate change. [Directed by Artrake Studio, narrated by Addison Anderson].

In this talk, we will look at what WordPress looks like as an Application Data Graph and how WPGraphQL enables a GraphQL API for WordPress and allows us to interact with the WordPress graph via GraphQL queries and mutations. In previous talks, (WordCamp US 2017, WordCamp for Publishers 2017, WordCamp Orange County 2017) I’ve talked a lot about the history of WordPress APIs and how GraphQL compares to them and helps solve some problems of using other APIs. This talk will focus less on the history of why WPGraphQL came to be and how it compares with other existing WP APIs, and focus more on how to use WPGraphQL, how to extend WPGraphQL to work for your site. We’ll start by looking at basic usage of WPGraphQL: querying posts, pages, terms, etc. Then we’ll explore some features of the query language such as variables, aliases, and field arguments. Then we’ll look at Mutations (creating, updating and deleting data) and we’ll discuss how WPGraphQL handles Authentication and Authorization, and other features like fragments. Throughout the talk we’ll look at the internals of WPGraphQL and how it goes from a request to the WordPress server to resolving data back to the client, and how it makes use of core WordPress technology to efficiently resolve data.

The internet is the single most effective information sharing tool in all of history. We can build on the work and progress of others in a completely unprecedented way. The implications for the progress of humanity are both serious and exciting! But it’s also in danger.

Do you know that if you have a picture of a duck having it face left or right can increase your conversions by 40%? Think this sounds silly? It is but backed by research. Spend some time to learn about what a/b testing is, what things to test, testing methodology and the best tools to use for your site. Everyone will get a handout of the very same checklist I use when A/B testing our client’s sites. One of our clients, an insurance company, increased leads by making just a small 2px change. When you launch a website, you are guessing. Sure the guesses are educated based on experience and data, but you can maximize your ROI with good A/B testing.

This talk will cover everything you need to know in order to create a plugin to start using on your own site. You won’t need to have any prior PHP or other coding knowledge to walk away with something you can use right away.

Making changes on a live server is always risky. And when things go wrong it’s not easy to diagnose the problems. You can setup a staging server for changes, but you still have to deploy files, and that takes time. Spinning up a local environment is essential for WordPress development. And it’s also very easy to do, thanks to Local by Flywheel. I will show you how to quickly spin up a local site. We will cover SSL, debugging, database management, and other features to help you safely build better quality WordPress sites in less time.
