Imagine if you could just pick up any coding problem and solve it. There's a way to get that "fingertip feel" for coding. And it comes from mindful, conscious practice.
Coding exercises are... fine. But there's a kind of exercise we can steal from another industry that works incredibly well. After this talk, you'll be able to create coding studies for yourself, not just find other people's exercises that are already worked out for you.
The talk is in Ruby. But the technique works with any language, library or paradigm. It's also good for pairing.
Rails 'magic' is just Ruby metaprogramming. You can understand Ruby's metaprogramming features and Rails' more unexpected systems in one go by building your own Ruby MVC web framework, structured like Rails.
This is a three-hour workshop, as delivered at RailsConf 2019 and Southeast Ruby 2019 (sorry, no video!). So I've helped over a hundred people debug this live as they typed it in :-)
Ruby 2.6 added a JIT implementation, called MJIT. How did it happen? How does it work? How do we use it? What code does it work well or poorly on? All this and more... But the video hasn't posted, alas, as of the beginning of 2020.
