Throwable is the supertype of all things that can be thrown. It often appears in codebases as an upper bound for error handling. Here's why you shouldn't do it.
We should all strive to write code that is harder—if not impossible—to exploit. Sometimes, however, the vulnerability comes from places we thought we could trust.
When I talk about KotlinJS, people often ask me “Why not just TypeScript?”. This article compares the type system and standard libraries to understand how different the languages are.
Over the years, many people have asked me why I prefer using GitLab over GitHub. Although an exhaustive comparison wouldn't be possible in a single article, I'd like to highlight a few points of interest.
A story about contributing to open source, how the community finds bugs before they reach customers, and a weird edge case I didn't know about.
Hexagonal architecture is one of the most popular software architectures at the moment. Let's dive into what it is, what it isn't, and how to know when a project isn't benefitting from it.
