Leading our day, Hakuna Automata talks about 5 tips for cultivating psychological safety. The basic idea is that you need to know whether your employees can communicate honestly with leadership about their job. In most companies, this type of communication is avoided and sometimes actively discouraged. Liz Keogh writes about BDD, Behavior Driven Development, as a three-headed monster. As with anything that Liz writes about BDD, you should be reading it. O’Reilly Media has an excellent post about the current state of machine intelligence 2.0. If you are interested in artificial intelligence, machine learning or data science, you definitely need to take a look.

As always, enjoy today’s items, and please participate in the discussions on these sites.
