Excellent stuff! Exactly the kind of things I'm looking to learn as a developer. I'm posting this to Hackr.io as well.
OK, but what the heck is it?
video tutorials for linux sysadmin-type tasks?
Oh. So it's stuff for people who can't read, I believe. Because most of sysadmin-type tasks are perfectly suitable for a short written manual or howto.
Or for those people that learn better by seeing the output presented. I like some of their guides, both the tutorial style and the videos.
