Things to add

1. Python

• type checking
• threading / multiprocessing / multithreading
• os and subprocess modules
• coroutines
  • asyncio module
• decorators
  • built-in decorators, like @classmethod
• subpackages and importing
• operators
  • e.g. walrus
• creating a generator using with: yield
  • @contextlib decorator
• built-in methods:
  • open()
  • property(get, set)
  • zip()
  • map()
  • copy() – copied thing changes props along with original??
• global space

2. Kubernetes

• everything

3. Docker

• expand / correct permissions and env variables
• registeries
  • Docker vs ECR vs GCR

4. Git

• Gitlab
  • CI/CD
    • .gitlab-ci.yml
    • external registries
• expand commands
  • write out commands evoked by shell functions
• rebasing vs merging vs cherry picking
