Youtube channel: Kurzgesagt - In a Nutshel
Stumbled upon this from a post by facebook page "Philosophy Matters".
Very well produced, entertaining and informative content. There's not that
much to say. Go watch.
The videos may be online somewhere else, but I only know of the youtube.com

vim command :reg
I messed up while writing this post, I pressed escape and U because I pasted
something into the terminal, didn't think about the fact that the paste would
be interpreted as being part of the edit, so I wiped all the text.. Luckily,
the :reg command in vim saved me by showing a list of stuff I've previously
written, allowing me to restore it.
