When you’re developing in Clojure, you’re interacting with a live system. You are in control, so you need to understand how the Clojure system works under the hood. In this lesson, we go over how Clojure executes code one expression at a time, how namespaces and Vars work, and how files can get out of sync with the runtime.
Video Lessons
Parts of courses on specific topics
Clojure Function Syntax
This lesson teaches the function syntax with minimalist examples. This lesson includes a video screencast. The video is 19 minutes long.
Clojure Namespace Declarations
This lesson teaches a subset of the namespace declaration to make ns forms that are readable and easily correct.
Clojure Twitter Bot
Have you ever wanted to make a Twitter bot? In this Clojure in One Hour lesson, I make a very simple Twitter bot in about 30 minutes. It’s ready for lots of tweets to broadcast to the world!
Closing Shop (Stopping Processes)
This lesson addresses some issues that came up with the switch to conveyor belts. How do we tell everyone to stop working when the trucks are loaded and ready to ship? We don’t want them to keep building cars. Learn about how to close channels so that they don’t accept any more work.
Cloud Monitoring
If you’re running a system in production, you’ll want to keep an eye on it 24 hours per day. There are now cloud monitoring options that collect information from your JVM all the time and will send alerts.
