@GabrielF While this technically answers the question, it would be preferable if you provide the key points in the link as part of your answer, in the off-chance the link ends up dying eventually. — Thomas W. 2 hours ago

@ThomasW. I understand your concern, and I believe that's quite an interesting issue, but don't I need permission (either from the author or the website) to copy the relevant parts? — GabrielF 1 hour ago

You've already linked to the source, @GabrielF. Leave the source link in place and all should be fine. (ubuntuforums.org won't kill you for that) You'll notice I did so on this answer to another question where I lifted the steps from their site and put them here, but I specifically said the source was not my own. That hasn't been sniped yet, because it's not me stealing information, I said "It's their work, I just copied it to here." — Thomas W. 1 hour ago

@ThomasW. I'm still not convinced... this doesn't answer this simple question: may you copy the contents of the blog such as you did? I can see that linking isn't very appreciated around here, but I'd rather follow this philosophy. The key point here is: I don't have the answer, I'm not sharing my knowledge... I'm sharing my finding. Shouldn't/can we move this to a chat or meta? — GabrielF 29 mins ago
