Akku is a package manager for Scheme that currently supports numerous R6RS and R7RS Scheme implementations.1 I was slow to embrace Akku because I encountered some initial friction with installation and setup.

As an impatient person, I typically use progress bars for any code that takes more than a few minutes to run. In a previous post, I wrote about creating ASCII progress bars in R and Racket.

One of the advantages of open source software is being able to view, review, and learn from source code. Both R and Chez Scheme provide tools for accessing source code.
