jan“Darwin wrote extensively on animal behaviors, local adaptations, and reciprocal relationships that speak to co-creation, not a fixed environment imposing design by negation.

Virtual Domain-Driven DesignAfter a wonderful session yesterday, we'll be back on July 16th at 16:00 UTC for an insightful session with Hibri Marzook on "Decoding Paradoxes: Why are many good ideas in Software Delivery counter-intuitive."We'll dive into counter-intuitive ideas in software delivery by visualizing socio-technical feedback loops in our systems. How does deploying more frequently improve quality? How does slack time in a team improve reliability? Why should we do it more often if it hurts?These perplexing concepts often leave CEOs bewildered. Improving software delivery means understanding these paradoxes and balancing social and technical dynamics. How do we deepen our understanding and explain these concepts to others?🗓 July 16th, 16:00 UTC<a href="https://techhub.social/tags/Complexity" class="mention hashtag" rel="nofollow noopener" target="_blank">#Complexity</a> <a href="https://techhub.social/tags/Thinking" class="mention hashtag" rel="nofollow noopener" target="_blank">#Thinking</a> <a href="https://techhub.social/tags/Sociotechnical" class="mention hashtag" rel="nofollow noopener" target="_blank">#Sociotechnical</a> <a href="https://techhub.social/tags/SystemsThinking" class="mention hashtag" rel="nofollow noopener" target="_blank">#SystemsThinking</a> <a href="https://techhub.social/tags/Agile" class="mention hashtag" rel="nofollow noopener" target="_blank">#Agile</a> <a href="https://techhub.social/tags/Coaching" class="mention hashtag" rel="nofollow noopener" target="_blank">#Coaching</a> <a href="https://techhub.social/tags/TeamTopology" class="mention hashtag" rel="nofollow noopener" target="_blank">#TeamTopology</a> <a href="https://techhub.social/tags/ComplexityTheory" class="mention hashtag" rel="nofollow noopener" target="_blank">#ComplexityTheory</a>More info: <a href="https://virtualddd.com/sessions/decoding-paradoxes-why-are-many-good-ideas-in-software-delivery-counter-intuitive/" rel="nofollow noopener" translate="no" target="_blank">https://virtualddd.com/sessions/decoding-paradoxes-why-are-many-good-ideas-in-software-delivery-counter-intuitive/</a>Looking forward to seeing you there! 🚀

⏚ Antoine Chambert-LoirEvaluating the operator norms of matrices New blog post on Freedom Math DanceLet E and F be normed vector spaces, over the real or complex numbers, and let u ⁣:E→F be a linear map. The continuity of uu is proved to be equivalent to the existence of a real number cc such that ∥u(x)∥≤c∥x∥ for every x∈E, and the least such real number is called the operator norm of uu; we denote it by ∥u∥. It defines a norm on the linear space L(E;F) of continuous linear maps from E to F and as such is quite important. When E=F, it is also related to the spectrum of uu and is implicitly at the heart of criteria for the Gershgorin criterion for localization of eigenvalues.However, even in the simplest cases of matrices, its explicit computation is not trivial at all, and as we'll see even less trivial than what is told in algebra classes, as I learned by browsing Wikipedia when I wanted to prepare a class on the topic.Follow the link to read… → <a href="https://freedommathdance.blogspot.com/2024/04/evaluating-operator-norms-of-matrices.html" rel="nofollow noopener" translate="no" target="_blank">https://freedommathdance.blogspot.com/2024/04/evaluating-operator-norms-of-matrices.html</a><a href="https://mathstodon.xyz/tags/LinearAlgebra" class="mention hashtag" rel="nofollow noopener" target="_blank">#LinearAlgebra</a> <a href="https://mathstodon.xyz/tags/ComplexityTheory" class="mention hashtag" rel="nofollow noopener" target="_blank">#ComplexityTheory</a>
