June 13, 2021 Zero-downtime restarts
It is inevitable that a backend service will need to get restarted to pick up a new code change, configuration change, or get out of an invalid state. In this show, I'll discuss why do we need restart services and what alternative ways are there to get around it. And then I'll talk about how to achieve a zero-downtown restart and it is not straightforward as one might think.

June 12, 2021 My thoughts on the CAP theorem
CAP stands for Consistency, Availability, and Partition tolerance. Understanding the CAP theorem can help engineers make better design choices when building distributed systems. In this show, I will explain the CAP theorem and how you can use it to make tradeoffs in your backend design. You probably already are using the CAP theorem without even knowing.
