the ultimate guide to an open source life, i spent 2 months on this, i hope you enjoy it!!! (youtube.com)
Rossman's 2 year project, 13 hour video course and very detailed wiki.
When he did the video guide he was going through and redoing his wiki, documented, to see if it actually worked, becuase yeah, there is a lot of linux documentation out there that doesn't actually work even if you follow the steps (perhaps because the machine they used already had dependencies and things installed). ... He also never has to update his wiki or video (except for links or typos), because each thing he wrote it as he tested it from scratch.
One thing he said was that with linux, if he ever gets something to work, he never changes it, even if some new thing says it's way better, he just assumed yeah but it might not actually work or be able to be set up, and this thing I have already works so there's no way he's changing from that... The end of constant new digital products and reconfigurations is products that work.
