This multi-language programming world of ours is getting in the way of doing our work of implementing software solutions to whatever problems we are tasked to solve.
As Uncle Bob pointed out in “The Last Programming Language”, the other fields have agreed use only one notation — mathematicians, musicians, and others already have. We eventually also will have to agree to use only one notation.
But for the mean time, I think all-programmers-learning-or-being-aware-of the Clean Architecture model might serve as an initial solution to this multi-language-programming-world problem of ours.
But if we are going to learn the Clean Architecture model, we need to have some sample projects that we can run and play with… because programmers, like me, who have but little experience in the software development world, cannot instantly produce code by only looking at some diagrams or by just listening to some abstracts ideas presented in a talk. 
We need to see code…
Uncle Bob did not give us a sample project in his talks and in his blog. He only have some code snippets in one of his blog posts, “A Little Architecture”, but not an entire sample project. (Maybe he will provide a sample project in his upcoming book?)
But, luckily, some of our other masters have provided us some sample projects that use the Clean Architecture model.
Here are some of them…
In .NET
Matthew Renze’s Clean Architecture demo (I cannot find his talk online. Maybe it was not recorded.)
- short interview about his talk
- slides — even though the video of the presentation is not available, his code sample is understandable through his slides
- code
In PHP
(Disclaimer: I know almost nothing about PHP… but I think this is one of the best samples available.)
In Android
Fernando Cejas’ sample project in Android
- “Architecting Android…The clean way?”
- “Architecting Android…The evolution”
- “Clean Architecture: Dynamic Parameters in Use Cases”
- code
In Python
Leonardo Giordani’s sample project in Python
You can google for the others…
