I worked as a sysadmin and developer in small, medium and large companies. My professional journey in IT began in 2013 and I can't shut up about the things I've learned.
I've been using zoxide and sgpt for about a year, and they are now a staple in my toolset - in fact often the first tools I install on a new system. In this post I will quickly demonstrate both of them and how you can start using
What can Plato's allegory of the cave teach us about software design? What we are supposed to deliver to customers is always: a shadow, a simplified perspective of complex shapes. Customers demand something easy to understand and one dimensional that "just works". A common trap that

Last time, we created a testable implementation of a simple function, that takes an order, computes some values like net / gross totals and tax, and returns the result so we can print it. Here is part 1 if you're interested. As a refresher, here is what that program

In this article I want to show you how to increase function purity, modularity and testability in inherently impure programs, based on a realistic code example. 🤠The following code snippets are not necessarily best practices. Each snippet is supposed to highlight one specific characteristic, without mixing in too many concepts
Chances are, you heard of functional programming, and maybe dabbled in it. But if it is not your main paradigm, you probably have some misconceptions about it. First of all, a disclaimer: I am still new to FP myself, but I have already wrestled with understanding it for at least

As already mentioned in my PHP article on this topic, I frequently store multi-line strings in my programs. Today, let's use ascii based game art for our example. Language version used in this article: Scala 3.6.2 The Artwork Here is the artwork of a book that

A common task I face when programming is to store multi-line strings in a variable. This may be related to templating for views, emails or configuration files for third party systems, or just writing readable inputs for tests. The naive approach First I want to show you the naive approach:
