Hexagonal Architecture

Conceptualized by Alistair Cockburn. Also known as "Ports and Adapters".

In a nutshell:

Application Driver -> Primary Adapter -> Primary Port -> Use Case -> Secondary Port -> Secondary Adapter -> External System/Side Effect

Docker with SSL and an nginx reverse proxy

Running your ASP.NET Core (or other) application in Docker using SSL should not be an overwhelming task. These steps should do the trick.

Run the following steps from a Linux terminal (I used WSL or WSL2 on Windows from the Windows Terminal).

1. Create a conf file with information about the cert you'll be creating

It should look something like the content below; call it my-site.conf or something like that.

Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
