I do think that knowledge should be free for everyone so you could try, use, extend, correct, share, etc anything you find here. The only thing I will ask you is to make a reference to this blog. In the same way, if you’d like to contribute to this site it would be great to include your own stuff here and a reference to you’ll be attached to it.
But what about licesing then?
I don’t know much about licensing and I don’t really care about it. So this site’s license is a compromise between you and me in which both of us respect everything I’ve written in the paragraph above.
As I said you could use anything included here the way you want, but do it at your own responsibility. That means that if something you read here breaks your computer, your network or your work’s farm of servers it’s you the one to be blamed for.
