Interview with Marijn Huizendveld
Marijn is the guest of this episode, and he brings his heuristic: Do NOT rewrite from scratch if it is in production (https://marijn.huizendveld.com/design-heuristics/do-not-rewrite-from-scratch-if-it-is-in-production). He gives examples of how to evolve software in production, reducing the risk of building the same thing in a new tech stack. We discuss how the software evolution is connected to the business model of an company, and seems a technical design, can even impact the revenue model.

Interview with Charity Majors
Our guest for this episode is Charity Majors. The pattern that serves as the stage for the episode is “Build Confidence” from the Object-Oriented Reengineering Patterns (http://scg.unibe.ch/download/oorp/OORP.pdf). Charity describes the infamous “death spiral”, where folks that produce code lack confidence in their processes and practices to deploy code to production. According to Charity, our job is not done until we close the feedback loop!
Charity also gives excellent advice regarding patterns and heuristics: to understand a pattern or heuristic, take one that you see working, and modify it. Learn what comes out of that!

Interview with Danyel Fisher
This week in the podcast, we feature Danyel Fisher. He brought the heuristic “Users are correct but not accurate” from his repository. As a starter, Danyel explains that users have goals that aren’t able to express well, and we need to use different methods to discover the needs. We discuss what makes a high performing team, and in his opinion, one of the distinctive factors is the usage of mixed methods for problem examination! And, he gave us a new heuristic to battle personal bias: “Delight and being wrong”!

Interview with Matt Lawrence
Matt Lawrence is our guest, and he is challenged with the biggest heuristic so far: “Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.”, also known as “Jakob’s Law”. The heuristic is part of the “Jakob Nielsen Usability Heuristics” and can be found here: https://lawsofux.com/jakobs-law/.
Matt shares his experiences when it comes to usability, and what challenges you are faced when the system users are attached to a website. We discussed the different techniques that are valid to fulfil the user's needs when it comes to usability.

Interview with Mathias Verraes
Mathias Verraes is the guest of this episode, and for the first time, we have more than one heuristic! Mathias brings three Loss Aversion heuristics from his personal repository. When we make decisions, we often do not explore options that have a risk of loss, even if that loss is balanced out by potential gains. These heuristics help you overcome that bias. We jump right into the rabbit hole, and Mathias brings the intersection of software engineering, psychology, and anthropology to exemplify the heuristics. During the interview, he shares techniques and practices that are part of his toolbox when working on software strategy and design.

Interview with Emily Bache
We are back with a new episode featuring Emily Bache. We start with a heuristic close to her work, “Working software is not enough, we need well-crafted software”. Emily shares her view on how code quality is essential, not only for the code maintainability but also to onboard new people on the team, increasing productivity. The interview flows towards team culture and management; she shares her experiences about how friction can arise in a team that produces software with no shared values and rituals that trickle down to code. She explains how all of those decisions and misalignments contribute to the complexity of the codebase.
