Useful NERs to develop?

[ramatopia]

Im looking for some useful ideas to develop NERs that take care of typical situations in order to practice and kill dead time i have at work while im not working on any project.

Could you help me with some ideas to practice that can be used by other developers in future situations?

Thank you!
