Cyber is Calvinball.

I gave a talk back in 2015 [1] which I think has held up rather well. My argument was that cyber is evolving in
unpredictable ways as we learn more about the domain. That the current state of the art has huge blind spots we aren’t
even thinking about. The next year was, of course, the 2016 disinformation campaign fed by cyber loot.

I feel that a great deal of cyber war literature is based on knowledge derived from...

We also discuss their decision to move to Kubernetes, and the benefits they received.

Bernd Rücker, who has contributed to multiple open source workflow management projects, discusses orchestrating microservices with workflow management.  As distributed systems evolve into a family of microservices that must handle long-running stateful processes with time-dependent actions, events, multiple paths through the system, and complex rollbacks, the workflow management model provides a way to ensure clear modeling, correctness, and separation of concerns.   Rücker recommends a federated model in which each microservice is paired with its own workflow to handle retries and other policies and failure modes around that service.  Robert Blumen spoke with Rücker about microservice architecture, event-driven systems, long-running stateful processes versus synchronous request/response, event handling, time-outs, and handling exceptional conditions with compensating transactions. Rücker compares the choreography versus orchestration models for collaboration and discusses why orchestration provides a better separation of concerns.  The discussion delves into the implementation of workflow management systems including persistence, scaling, event handling, timers and scheduling, and similarities to CQRS.  The discussion wraps up with monitoring and visualization.

I have to begin this post by apologizing for not realizing January was "International Creativity Month," but it should never be too late to celebrate creativity, should it?

The intent of International Creativity Month (founded by motivational speaker and author Randall Munson) is to remind people and organizations to capitalize on the power of creativity. My personal belief is that we are all creative in our own ways, but we might feel our creativity isn't wanted whether at school or work and we kind of "lose" our creative ability.

I believe we should encourage creativity with students, educators, and across all levels of employment. As Dictionary. com states:

Creativity is the ability to transcend traditional ideas, rules, patterns, relationships, or the like, and to create meaningful new ideas, forms, methods, interpretations, etc.; originality, progressiveness, or imagination: the need for creativity in modern industry; creativity in the performing arts.

So why wouldn't we want to champion the creativity within individuals? Without creativity, as individuals, we become stagnant in our thoughts and development as do our products and services within a business setting.

In a belated celebration of International Creativity Month, I wanted to offer some resources for creativity:

The Link: International Creativity Month: found on ipl2 – news and information, this resource highlights Randall Munson's newsletter and  illustrates how creativity is implemented in workplaces, in education, with food, with children, and across cultures.

The Center for Creative Learning: this site believes that people of all ages can improve their skills and ability to use creative and critical thinking, problem solving, and decision making, and that research on learning style helps us to understand how people develop and use their talents in unique and personal ways. They offer free resources, i.e newsletter, journal article reprints, sample activities, and ideas on assessing creativity (Assessing Creativity: A Guide for Educators and Assessing Creativity Index: a database of creativity tests and inventories)

Center for Excellence in Learning and Teaching: Created by Iowa State University, this site includes links to online resources, techniques for creative teaching, and evaluating creativity, etc.

The Torrance Center, University of Georgia: this site provides PowerPoint presentations, podcast lectures, activities and resources on creativity.


Is Creativity Innate or Can it be Learned?: This post found on the CareerTech Testing Center blog highlights a study released by Adobe entitled, Creativity and Education: Why It Matters.

The Phenomenons Called Curiosity and Creativity: Another post found on the CareerTech Testing Center blog highlights the concepts of curiosity and creativity.
