Some tech I keep an eye on or research. My github starred repositories have a more complete list.

Linux Namespaces

The Linux namespace additions to the kernel have proved extremely useful. Containerization solutions like Docker, Podman, LXC, or Kata Containers make deployments and testing highly reproducible. As a lightweight alternative to virtual machines, they effectively reshaped the world of shared infrastructure.

Artificial Intelligence / Machine Learning

An interesting area to be understandably excited about. The consumer/developer frameworks are simple and useful enough. The math and training new models is a bit complicated. I worry about security and the importance of data privacy.

Cross Platform Mobile Frameworks

React Native, Flutter and Xamarin are most interesting to me. A holy grail for developers to save development time and have a consistent user interface. There are trade offs like performance or lacking endless scrolling, however the native bridge is always there if necessary.
