Interesting Things on the Internet: May 13th 2019

• Tukey, Design Thinking, and Better Questions. Excellent thoughts on data science (I need to read the original paper too, written in 1962!). "Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, which can always be made precise."
• Finance for non-accountants. Excellent primer on how to read a company's accounts, for non-accountants like myself (and most people).
• Radically Open Security: Non-profit Ventures. Interesting set of rules for setting up non-profit businesses. Good to see more examples like this knocking around.
