Clojure error messages and stacktraces are the number one most complained-about feature of Clojure. We look at some tips and resources for dealing with them.
Video Lessons
Parts of courses on specific topics
Card functional abstraction
This lesson teaches how to use functional abstraction to make changes to data structures quick and easy. This lesson includes a video screencast, a git repo, and two exercises. The video is 14 minutes long.
Card Representations
This lesson demonstrates and evaluates many different representations of playing cards. The lesson includes a video screencast, a git repository with all code, and some exercises. The video is 14 minutes long.
Checking our insertion
Now that there is data in the database, we can start to ask question about it. How many rows were in the data set? What were the header names? We use those to check our insertion and debug some issues.
Choosing a JDK–licensing, support, and upgrade schedule
Oracle has recently changed their licensing terms. Before, we recommended using Oracle’s JDK build. It was free for commercial purposes. But it’s no longer free. Now we recommend using AdoptOpenJDK.
Choosing where to store state
There are four places Re-frame allows to store state in. We go over a framework of three criteria to decide where to put it.
Classes and Reflection
Java has a good story for reflection: just ask the object for its class and ask the class for a list of methods. Voil脿! You know what methods you can call. This lesson demonstrates reflection with some examples.
