The Next Abstraction

Or, Why AI Is Not Replacing Us

Once in a while, I like to read a book about a programming language I have been using for a while to find new tricks or to refresh and sharpen my knowledge about it.

Programming Ruby 3.3 (5th Edition)

Programming Ruby is the most complete book on Ruby, covering both the language itself and the standard library as well as commonly used third-party tools.

In which I finally understand ruby’s class model, and the crucial fact that class methods are not instances methods of the Class class.

The official Ruby documentation page at https://www.ruby-lang.org/en/documentation/ has gotten a much-needed update.

Thanks to @zenspider for taking charge on fixing this!

(I should note that it now directly references the Pickaxe, but it's better for lots of other reasons, too...)
