In the past I wrote a simple cookbook to explain this process but now this is as simple as possible. Don’t forget ssh-copy-id is the most easy way to add your ssh public key in remote servers.

My new posts will be in english as you can read in this post because I want more interactivity with readers from the start of the blog I have a very low rate of comments. I think this is because my technical posts are too much specific and then when somebody has some problems doesn’t speak catalan and cannot leave a comment asking their doubts.

In my humble opinion this new chapter of technical blog can arrive to more people because the language of technical community around the world is english. In the other hand every day I need to have more practice writing and talking english in my work because national market is dead and we need to expand our project around the world. So this effort to write technical posts in english will be like english practices for me.

Every new post will have a disclaimer at the begining of the post for my errors writing english and if you can help me to improve my english, please, leave comments fixing my errors.
