  • @DOES_EUR: .⁦@ScottHavens⁩ talking about having to rebuild a cluster from the ground up at @jet #does19 https://t.co/1xtpiIyDBO
  • @seizethedave: Purity means the isolation of computations from the real world, that computations and data are interchangeable [can be cached] and there are no "dual writes" #DOES19
  • @seizethedave: Immutability means message-based communication, e.g. event sourcing #DOES19
  • @seizethedave: Principles of FP:

  • immutability

  • actions (verbs), not objects (nouns)

DOES19

  • @seizethedave: Walmart bought Jet because Jet's tech stack looked "cool" 😎 #DOES19
  • @seizethedave: Next up at @DOES_EUR is "Forging a Functional Enterprise: How Thinking Functionally Transforms Line-of-Business Applications" with @ScottHavens #DOES19
  • @michaelswinslow: I get refueled at #DOES19 events. They inspire me to continue to be a change agent, to move forward as a team (not by myself), to reflect on successes and learn lessons from failure. (Notice, not one mention of CI/CD, Automation or On-Call)

  • @seizethedave: What are the benefits of event-drivem systems? #DOES19
