Conquering Kubernetes with Emacs

Specific Annoying workflow

Listing pods with kubectl get pods, then select a pod name and copy paste it into kubectl logs [pod name]

Why?

• I want to streamline my workflow and stop using the terminal
• learn more about kubernetes
• main kubernetes extension for Emacs out there is greedy for permissions

Rough Notes about CQRS and ES

Once upon a time…

I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).

I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).

It seems inevitable to throw Domain Driven Design (DDD) in to the mix.
