There is nothing that can make me turn away from *UNIX system.
My preferred technologies are the ones that i don't know, especially if related on BE system/microservices and, of course, they run on top of Linux sys.
If these three things are not linked during my "workday" i can't be as useful as i want to be.

- Neural Network, Classifier, Clustering: scikit-learn
- Micro services
