I was trying to read about RBAB (Role-Based Access Control) and ABAC(Attribute-Based Access Control); after some reading - I realized, as a software engineer - it’s way more easier when you get to read code - So, I started to search for open source project which implements access control infrastructure, and stumbled upon Casbin.
Always been facinated by the ways - data structure’s can enable better storage and faster queries.
BitMapped Indexed Storage - is useful while using Columnar Databases - where per column data is stored together.
We were working on a custom algorithm to optimally grab images given a list of area. Every image grabbed is written into an object store with a generated hashkey. The haskkey can be used to query the recorded data - when we would like to play them back.
Introduction: Airflow is a platform to programmatically author, schedule and monitor workflows or data pipelines. It was originally developed and open sourced by Airbnb, later joined Apache Software foundation’s incubation program in 2016.
Source Code: PyPlugins
Any infrastructure should always have the capability to extend itself. It would be better if the functionality is added by a contributor - who is not part of the core team.
