# Closing Thoughts

Unix seems like a good investment

We hope so was this class

If you would like to learn more, there are followups at Matfyz:
- Unix Administration
- Linux "principles and means"
- Advanced Unix Administration
- (Embedded) Linux Programming

If you liked the experience and would like to share it with the next year's
batch, please do **talk to us**.

_That is how we became TAs, too._
