December Software Links

Some of my favorite links from December. If you have any good links I missed pass them my way.

What you learn over 5 years is that every dependency, every line of code, every test, every feature is a DEBT or outage, waiting to happen.

continuing my trend of having something from @davetron5000 each month, and this month I have two ;)

Software Development

• one-click PDF microservice
• on Kafka and Redis streams
• distributed system with one process representing every user / shared resource in Elixir, great talk @myobie
• Understand why Serverless matters another great write up by @davetron5000

OK, updated my pre and post production testing diagram based on feedback I got. Still something I missed out? pic.twitter.com/c3Q2wUSQdI

Ruby

• GraphQL Performance in Rails
• Memory and Performance improvements for Pluck
  • If you have to iterate through huge collections and don’t need the full object this is a huge win
• Malloc Can Double Multi-threaded Ruby Program Memory Usage
  • Sidekiq users can reduce memory use by 1.5-4x with a few config/environment changes

DevOps

• Rapid Release at Massive Scale deployment at Facebook

Tech Management

• What does a CTO do?
• On Timely Code Reviews

Random

• 10 years in and nobody has a use case for blockchains
  • yes this is a bit of a clickbait title, but many points still hold true. The claims of distributed aren’t holding up to well with real world usage of blockchains.
