Kodsnack 570 - Debug your ideas, with Eric Normand

<p>Fredrik is joined by <a href="https://ericnormand.me/">Eric Normand</a> for a discussion of debugging your ideas through domain modeling, using Eric&rsquo;s concept of lenses to find more good questions to ask.</p> <p>Eric is writing a book about domain modeling and has developed the concept of lenses - ways to look at various aspects of your domain, model, and code in order to better consider various solutions and questions.</p> <p>Why? Because design is needed, but is easily lost in the modern urge to be fast and agile. There&rsquo;s a lot you can and need do on the way to a working system. Eric pushes for design which is an integral part, perferably right in the code, rather than a separate one which can become outdated and separated without anyone noticing. Just spend a little more time on it.</p> <p>Tricks for seeing your domain with fresher eyes.</p> <p>Change is <em>not</em> always maximal and unpredictable! But thinking it is can lead to a lot of indirection and abstraction where a single if-statement could have sufficed for years.</p> <p>Refactoring as a way of finding the seams in your model. What is the code actually supposed to do? How does it actually fit with the domain?</p> <p>Recorded during Øredev 2023, where Eric gave two presentations about the topics discussed: <a href="https://ericnormand.me/speaking/oredev-domain-modeling-2023">Better software design with domain modeling</a> and <a href="https://ericnormand.me/speaking/oredev-functional-architecture-2023">Stratified design and functional architecture</a>.</p> <p>Thank you <a href="http://www.cloudnet.se">Cloudnet</a> for sponsoring our <a href="http://en.wikipedia.org/wiki/Virtual_private_server">VPS</a>!</p> <p>Comments, questions or tips?
