Clojurians Podcast

Pierre-Yves Ritschard (https://twitter.com/pyr) will be presenting: "Orchestrating the cloud with Clojure" While orchestration of physical resources has historically been a task for Perl and YAML, we will show how it is a perfect match for Clojure's data processing abilities. With a mix of basic constructs (FSMs, CSP, SQL) and some of Clojure's superpowers, we will show the architecture of a typical orchestrator at Exoscale, one of the leading European Cloud alternatives. Pierre-Yves is CTO and co-founder at Exoscale where he is responsible for architecture and strategic technology choices, relying on experience in the architecture of very large corporate systems as well as technical product design in several startups.

Title: **donut.system: your new favourite component library?** Speaker: **Daniel Higginbotham** Daniel Higginbotham (https://twitter.com/nonrecursive) will be presenting: "donut.system: your new favourite component library?" Daniel will introduce donut.system (https://github.com/donut-power/system), a new alternative to Integrant, Component, and friends. He'll show how it addresses some of their limitations and could provide a better foundation for a Clojure web-app framework. Daniel is the author of the very popular "Clojure for the Brave and True" book https://www.braveclojure.com/. He loves making things and helping others make things.

Speaker: **Leandro Doctors** Code: https://github.com/allentiak/bob-2021... Leandro Doctors (github.com/allentiak) will be presenting: "Combining clojure.spec, Design Recipies, and Domain-Driven Design" I will share a method to systematically and comprehensively evolve a domain model, complementing use cases and "software recipes" with (clojure.spec-based) specifications. This approach facilitates finding inaccuracies at the edges of our in-growth domain, allowing us to: 1) supersede the de-facto "tinker until it works" standard with a systematic "define-specify-verify (repeat)" cycle; 2) complement the traditional mitigation of both internal and parameter validation errors. Leandro is an IT geek from San Juan (Argentina) who rediscovered his love for programming thanks to Clojure. He has been involved in peer production communities (free software, free culture & the like) in one way or another for over twenty years now. After spending a few years between three different continents (Europe, South America and Africa), Leandro is currently back in his hometown. For how long will he remain there? Only time will tell.

How to apply principles of functional programming, but for package managers and operating systems? A brief introduction to Guix System and NixOS, why they are so similar to what we do in Clojure and why should we care.
