I publish a few programming newsletters that helps developers stay up to date through Bonobo Press.
.NET and C# developers will find useful resources on topics like performance, multi-threading, WPF, ASP.NET, .NET Core and other related topics.
Mostly focused on web development in React.js but also includes some resources on React Native and libraries around the ecosystem like Redux, MobX, WebPack and others.
This is a language agnostic newsletter that features interesting articles from different platforms and subjects. Every developer should subscribe to keep an eye on the current trends.
Elixir Digest is one of the first and longest running Elixir newsletters and it delivers great articles about core Elixir language or Phoenix web framework.
This digest is for statisticians, data scientists, machine learning and AI experts, or programmers that would like to get valuable insights into the field.
For all the others checkout my github repositories or codeplex if you fancy some legacy code.
