Hello! My name is Aleksandr, and I write this blog. Sorry, my English is poor, but I try to improve my language skills. The blog is my hobby. I work system administrator for almost twenty years. I have a lot of experience. But I want to evolve, so I decided to learn to program. I am learning Ruby on Rails, so the theme of the blog was changed. Now I will write more about Linux Ubuntu, Ruby, Postgress, etc.
