Soft Intellect Linux Course

Recommendations for the course:

  • Think about the material, try to explain to yourself or to your classmates.
  • Make all the homeworks, they are really important, do not skip any.
  • Ask me as many questions as you want, it's not about how you look, it's about your knowledge after the course ends.
  • Experiment in your virtual machine, do not be afrad, that's why it's virtual.
