David MacIver is most known for pushing the adoption and ergonomics of property testing in software with his testing library Hypothesis. Hypothesis is well regarded and widely used in the Python programming language community, and it introduced a handful of innovations that are now quite widespread in the practice of property testing. You'll hear more about Hypothesis during the podcast, as we talk about what he's learnt pushing the boundaries of a domain. Then, we shift gears to talk about his coaching practice. David specialises in helping programmers with self improvement, more effective learning, and developing soft skills, which many computer programmers are likely to struggle with, in ways that may limit their careers or their personal development.David's Substack — https://drmaciver.substack.com/David's Twitter — https://twitter.com/DRMacIverHypothesis — https://hypothesis.works/, docs: https://hypothesis.readthedocs.io/en/latest/Ethics of False Negatives in Interviewing — https://www.drmaciver.com/2019/06/the-ethics-of-false-negatives-in-interviewing/Life as an Anytime Algorithm — https://notebook.drmaciver.com/posts/2020-03-23-15:52.htmlIf You're Stuck, Try Something Different (on chopsticks) — https://drmaciver.substack.com/p/lateral-movesHow To Do Hard Things — https://www.drmaciver.com/2019/05/how-to-do-hard-things/Stargate Physics 101 (fanfiction) — https://archiveofourown.org/works/3673335David on why people struggle with mathematics — https://twitter.com/drmaciver/status/1422208261349052420How to Explain Anything to Anyone — https://www.drmaciver.com/2018/10/how-to-explain-anything-to-anyone/0:00 Introduction1:09 What Hypothesis Is3:47 The Story of Hypothesis6:43 Hypothesis's Contribution to Property Testing12:51 Exploring the Design Space for Hypothesis17:24 When David Knew He Was On To Something with Hypothesis20:35 From Hypothesis to Coaching25:21 Emotional Reactions as Legacy Code29:08 Why David's Approach to Self Improvement Works for Programmers31:15 Ethical Problems with Optimising False Positive in Hiring37:44 Ways that Programmers Harm Themselves in Their Careers43:28 What Non-Technical People Get Wrong when Dealing with Programmers48:00 Applying Lessons Learnt from Hypothesis to Coaching50:03 Rigour in Self Improvement Writing56:30 Explaining Computers to Non Technical People01:02:55 The Nature of Mathematical Expertise01:11:32  David's Practice with Teams and Organisations01:14:23 Getting Better at Sprint Planning

Dr Lia DiBello is the CEO, President, and Director of Research of WTRI (Workplace Technology Research Inc), and Senior Scientist at Applied Cognitive Sciences Labs Inc. She is a cognitive scientist as well as a businessperson. In the late 2000s Dr DiBello discovered in an NSF-funded study that all great businesspeople share a common mental model of business, and that mental model can be used for all sorts of interesting things, including the assessment of business expertise, which she did — she was the principal inventor of something called the FutureView Profiler. In more recent years, Dr DiBello is more well known for her work on accelerated expertise — she published a book with a few other researchers in 2016 with that very title. She and her team have created something they call the Strategic Rehearsal, and this actually stemmed from her PhD work, where it was called the OpSim. What the Strategic Rehearsal allows WTRI to do is to accelerate the acquisition of business expertise in the businesses that they consult for, and her training interventions have been used in industries as diverse as biotech, pharma, manufacturing, financial services, and others.- The Triad Mental Model of Business, paper: https://wtri.com/wp-content/uploads/2015/06/Informed-By-Knowledge-Chapter-12.pdf - A summary blog post of the triad mental model: https://commoncog.com/blog/business-mental-model/- FutureView Platform — http://futureviewplatform.com or https://acsilabs.org/- WTRI — https://wtri.com/- List of publications by WTRI, which, if read chronologically, includes a full history of the Strategic Rehearsal — https://wtri.com/research/publications-by-wtri/- Lia's LinkedIn — https://www.linkedin.com/in/liadibello/- Lia's Twitter — https://twitter.com/LiaDiBello4- Gary Klein on WTRI's training with Rio Tinto, on miner safety — https://www.psychologytoday.com/sg/blog/seeing-what-others-dont/201803/training-if-your-life-depended-it- The Oxford Handbook of Expertise — https://www.oxfordhandbooks.com/view/10.1093/oxfordhb/9780198795872.001.0001/oxfordhb-9780198795872- Accelerated Expertise — https://www.amazon.com/Accelerated-Expertise-Research-Applications/dp/184872652X00:00 Introduction01:32 Lia's Story04:49 The Triad Mental Model of Business10:38 Transfer of the Triad Between Business Domains16:18 The FutureView Profiler Explained20:42 How She Gets Her Clients To Accept Profiler Recommendations25:21 The Midwest Foundry Story40:14 Cognitive Agility47:32 How Great Businesspeople Learn in the Real World51:08 How This Has Affected Her Practice as a Businessperson54:42 What Lia is Currently Working On1:01:10 The Cognitive Science Behind the Strategic Rehearsal1:09:47 Piaget and Vygotsky's Theories of Expertise Development1:17:50 The General Form of the Strategic Rehearsal1:21:56 Non-Business Applications of the Strategic RehearsalThe coffee company Lia mentioned: https://amorperfecto.com/The Hollywood Bowl performance: https://www.hollywoodbowl.com/events/performances/1258/2021-08-27/carlos-vives-with-the-la-philSome words from Amor Perfecto to describe what they do:This is a coffee movement launch. For almost two centuries coffee has been at the service of the intermediaries and not of the coffee growing countries. Amor Perfecto, in collaboration with amazing people like Carlos Vives, his wife, Claudia Elena Vasquez and their Tras La Perla Foundation, is going to push to rebalance the unfairly tilted value chain of coffee. Every one in the coffee world knows it exists. Equally important, the product of Roasted at Origin coffee by Amor Perfecto, harvested, roasted and set to you from the mountains of Colombia is a uniquely amazing coffee. It might be the best tasting coffee available today, because producing coffee where it is grown makes a much fresher, better tasting coffee. As Luis Fernando Velez says “have you ever seen the French exporting containers full of grapes to make champagne in Brooklyn?” Coffee should be no different.
