You can only pick two: Consistency, Availability, or Partition Tolerance. Choose wisely.

Building interactive labs for software engineering fundamentals
Welcome! Here I build interactive learning labs that make software engineering principles stick. Topics include engineering laws (Brooks's, Amdahl's), productivity principles (Pareto, Parkinson's), system design, algorithms, team dynamics, and project management.
Explore all the labs here ➡️ Learning Lab.
I also post content on my YouTube channel.
