developers as a group is a whiny bunch of children, arguing over where to place the curly braces, if there should be space after an opening parenthesis and a whole other bunch of equally stupid stuff. https://dotslashme.com/posts/the-tools-of-the-trade/ Mon, 18 Dec 2017 08:07:32 +0100 https://dotslashme.com/posts/the-tools-of-the-trade/ A lot of my frustration with developers is that they don’t
