This is the 4th post in the Exercises in Programming Style focus series. This week’s post will be back to fundamentals, as the constraint is to use recursion. Recursion in computer science is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem (as opposed to iteration). The approach can be applied to many types of problems, and recursion is one of the central ideas of computer science.

This is the 3rd post in the Exercises in Programming Style focus series. In previous posts, we had a simple problem to handle - find and sort the 25 most frequent words from a file. Then, we had to comply with different sets of constraints regarding the code: first, no variable but a single untyped array; then, only a stack and a heap. This week, the constraint is to achieve the goal with the shortest code possible. For that, the usage of Kotlin’s stdlib is more than welcome.

This is the 2nd post in the Exercises in Programming Style focus series. Last week, we had our first taste of Exercises in Programming Style. Remember, the goal is to write a simple program, but to comply with some constraints. The previous constraint was that there was only a single variable available, an array. With a statically-typed language such as Kotlin, it required a lot of casting variables to their correct types before using them. This week, the constraint is as radical, but different.

This is the 1st post in the Exercises in Programming Style focus series. Recently, my colleague Bertrand lent me a copy of the book Exercises in Programming Style by Cristina Videira Lopes. Among all the books that sit on my reading pile, I decided to put it on top, and started reading right away. The concept behind the book is pretty simple, but very interesting: there is a problem to solve with code - search for the 25 most common words in a text file. But here’s a twist.

I manage my Jekyll blog in a Git repo. My publication process uses 2 branches: master contains all production content, and feature/newposts has the new blog posts, ready to get published, one commit per post. To publish an existing post: I check the to-be-published post in the feature/newposts branch. Then, get the associated commit. And cherry pick it in the master branch. Finally, I push.

I started working with Git some years ago, and to be honest, it was not easy to pick up. It’s a huge beast, and there are several ways that can help to tame it. On the web, most articles focus on creating command shortcuts. In general, this goes like: instead of writing git pull --rebase, let’s create a shortcut to type gpr.
