My First Drupal 8 Plugin OR: How I Learned to Stop Worrying and Love Drupal 8

This will be a live version of my blog series (1, 2) on the Drupal 8 plugin API, specifically as it concerns blocks.  hook_block_info and hook_block_view are gone in Drupal 8. What's more the whole paradigm of creating blocks through the hook system is replaced with the Plugin API.  In this talk, I'll show how to create a "hello world" block using the Drupal 8 plugin API, and then dive a little deeper and create a simple next/previous navigation using the same strategy.
