How to Create Neural Network in Elixir Using Nx and Axon
Neural networks mirror the behaviour of the human brain, enabling computer programmes to recognise patterns and solve common problems in the fields of artificial intelligence, machine learning and deep learning.
Nowadays neural networks are used frequently for various tasks such as text translation, face identification, recognising speech or handwritten text, control robots and autonomous vehicles, image recognition, image classification and many more.
If neural networks are becoming so popular it would be good to create them in an easy way and the Axon library which is built on top of Nx allow to do that in Elixir.

Ecto.DevLogger - an alternative logger for development
It inlines bindings into the query, so it is easy to copy-paste logged SQL and run it in any IDE for debugging without manual transformation of common elixir terms to string representation (binary UUID, DateTime, Decimal, json, etc). Also, it highlights db time to make slow queries noticeable. Source table and inlined bindings are highlighted as well.
