This is the 14th post in the Exercises in Programming Style focus series. So far, we solved the word frequencies problem with code alone. This week, we will solve it with the help of infrastructure. And with this specific problem at hand, what better fit than the database? We can approach the problem by loading the data read from the files in the database, and retrieving the top 25 words with the relevant query.

This is the 13th post in the Exercises in Programming Style focus series. In this week in Exercises in Programming Style’s post, we will cover one of the foundation of Functional Programming, I/O. In Functional Programming, functions should be pure: a pure function’s return value must only depend on its input parameters.

This is the 12th post in the Exercises in Programming Style focus series. This week, we will focus on Aspect-Oriented Programming, a powerful programming technique: In computing, Aspect-Oriented Programming is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns.

This is the 11th post in the Exercises in Programming Style focus series. This week’s post is dedicated to reflection: In computer science, reflection is the ability of a process to examine, introspect, and modify its own structure and behavior. The original Python solution is handled in different ways: the exec() function.

This is the 10th post in the Exercises in Programming Style focus series. In last week’s post, we solved the now familiar top-25-word-frequencies-in-a-text-file problem by using Event-Driven Programming. When the number of observer-subject pairs grows, an alternative is to migrate to the Event Bus. The Observer pattern is a messaging pattern: an Observer subscribes to a Subject. When the later emits an event, the former is notified.

This is the 9th post in the Exercises in Programming Style focus series. In the post from two weeks ago, we solved the problem using Object-Oriented Programming: we modeled the problem space using objects. For an object to communicate with another one, a dispatch() method was made available. Remember before the web was ubiquitous? Graphical user interfaces were already a thing.
