Hexagonal architecture, also called ports and adapters, is a software design approach that helps structure an application by clearly separating the core logic from technical details and external systems. Instead of shaping your app around frameworks, protocols, or storage, you keep your focus on what the application does, and let everything else connect to it through interfaces. The pattern isn't tied to any specific language. The examples in this article are written in PHP to show how the idea can be applied, but the approach works the same way in any backend system.
Setting up a MySQL 8 server can seem complicated at first, but with a clear and structured approach, the process becomes much more manageable.

The instructions are practical and direct, suitable for environments that require reliable and straightforward configuration.
CQRS stands for Command Query Responsibility Segregation. It's a pattern that separates how an application reads data from how it writes data. This approach can help structure code more clearly, especially in systems that deal with complex business logic or need to scale certain operations differently.
When working on simple Arduino projects that need basic navigation or input, the AD keyboard module is a handy little tool. It's a 5-button unit that behaves like a directional pad, with four arrow-style buttons and one additional button. It doesn't require any soldering or setup, which makes it a practical choice for prototyping or small projects. You can plug it in and start using it right away, thanks to its three-pin layout and built-in resistors.
