Creating Animations and Interactions with Physical Models

Article

  • Maintain the sense of physics via momentum and "virtual" friction
    • Makes interactions feel more natural (we intuitively understand the conservation of momentum)
  • Spring values:
    • Spring constant: affects the speed of the feedback (tension?)
    • Damping: affects the size of the feedback (force?)
  • You can slow things down with constant deceleration, or friction
  • Humans are great at tracking linear motion, but terrible at tracking zoom
    • Avoid linear translations if the performance is bad!

Kubernetes monitoring with Prometheus in 15 minutes

Article

  • Kubernetes Operator: an application-specific controller that extends the Kubernetes API to create, configure, and manage instances of complex stateful applications on behalf of a Kubernetes user
  • Prometheus Operator provides easy monitoring for k8s services and deployments besides managing Prometheus, Alertmanager and Grafana configuration.
  • ServiceMonitor
    • A Custom Resource Definition
    • Abstract how services are targetted by Prometheus, by defining custom rules (e.g. matching a label)
  • AlertManager
    • Handle incoming alerts (dedupe, group, etc.) and send them to receivers

A Big Little Idea Called Legibility

Article

  • A repeated pattern of failure by being fooled by your subjective lack of comprehension (of a complex system) into making false simplifications, attempting to maximize "legibility"
    • Maximizing "organization"
    • E.g. applied to states trying to simplify taxation, control, identity, etc.
    • What gets measured gets maximized
  • Real societies look random, but are actually pseudorandom (e.g. random number vs. digits in pi)
  • Sometimes replacing locally optimal solutions with globally optimal ones (e.g. standardization of time)
    • Engineering a shift in optima and power

Eight Metaphors of Organization

Article

  • The organization as:
    • Machine
    • Organism
    • Brain
    • Culture
    • Political system
    • Psychic prison
    • System of change and flux
    • Instrument of domination

Aggregation Theory

Article

  • Aggregation Theory: describes how platforms (i.e. aggregators) come to dominate the industries in which they compete in a systematic and predictable way
  • Value chain: supplier, distributor, consumer/user
    • Outsized profits:
      • Horizontally integrate in one segment
      • Vertically integrate between two to gain UX advantage
  • Before internet, control depended on controlling the distributor
    • Most integrated backwards into supply rather than forward into consumers: costly individual transactions means that controlling the smaller (and less chaotic) segment provides more leverage
  • With internet, distribution is free, supply has grown, transaction costs minimized
    • Allows companies to focus on the consumers with UX, and the supply will be attracted to those who have the most scale

Defining Aggregators

Article

  • Must have three characteristics:
    • Direct relationship with customers
    • Zero marginal costs for additional customer
    • Demand driven networks with decreasing acquisition costs (e.g. network effects)
      • Abundance in supply; most value comes at discovery and curation
      • Suppliers are drawn by more users; users are draw by more suppliers

How to build a successful movement in 4 steps

Article

  • "New power operates like a current. It is made by many. It is open, participatory and peer-driven. Like water or electricity, it’s more forceful when it surges. The goal with new power is not to hoard it but to channel it."
  • Find connected connectors
  • Be frictionless; everyone else is also veying for attention and resource commitment
  • Move people up the participation scale; keep them engaged
    • Complying
    • Consuming
    • Sharing
    • Affliating
    • Adapting
    • Funding
    • Producing
    • Shaping
