Which to use? and/or vs &&/||  

I love these short tips, thanks :)

Nice video. Love how concise and clear it is!

Hi German! Thanks for the videos.. Just watched your DDD talk and it was so spot on! And I came here from your Elixir Streams Blog. (Side not, can you add the publishing date of your posts, just to have a sense of when you released them.. E.g. I clicked the video just to see it was posted a day ago!.. Anyway.. Keep up the good work!)

Great video. Great examples. A minor mistake: 3:00 You said: "or is expecting booleans on both the left and the right hand side and the same is true of and" But that's not true. When the first value is a boolean, the second can be a non boolean. iex(1)> true and 1 1 iex(2)> false or 2 2
