Hello!
"I want to became more pro in linux, linux Sysadmin, programmer and so on"
i have bookmarked some sites long ago and saved it. I have several links that
can help you what you want, as well i kept it to myself because i am
interested in starting to learn programming. I didn't before because it was
not the right time to do so. So like you i am finding what is best to me to
start with.
But before that "what forums do you use? what do you recommend?" to me the
best forum is trisquel because community is very active. I tried other forums
like debian in portuguese but well... several of them can recommend
proprietary things to install and/or they are very inactive and you need to
wait looooong time to get your answer...
Now, let's go start with the request of programming. As you don't specified
what "programming language" you wanted i will put all i have here. So far the
links i have or would like to learn are:
http://www.ftacademy.org/courses
https://www.w3.org/2002/03/tutorials.html
https://training.linuxfoundation.org/
http://www.tldp.org/LDP/nag2/index.html

http://www.openculture.com/freeonlinecourses
http://www.academictutorials.com/w3c/
http://www.oreilly.com/

Of course... some sites are more useful than others but anyway i placed here.
