The other day when visiting my family, under a large pile of torn up binders and laminated documents, I found my sibling’s old 2013 MacBook Air. I thought it would be wasteful to just leave it there so I picked it up and took it to the lab, AKA home. I discovered that the laptop was password locked with my sibling’s user and password. Since it must’ve been laying at my family’s house for a few years at least, and we as human’s have a tendency to forget our credentials, I decided to save the attempts and just format it and start with a clean OS.

A few months ago, I received a highly-anticipated 2020 32GB, 2.3 GHz Quad-Core Intel Core i7 MacBook Pro. Highly-anticipated because I already had one stolen (a 2019 version) earlier last year in a robbery in an AirBnB apartment I was renting while I was staying in Barcelona. It was quite a dramatic story but I won’t get into the details. This is a tech blog after all.

In this tutorial we deploy a PostgresSQL database in Kubernetes cluster.

Today I received an escalation from one of our largest and most strategic customers. Over the weekend, the customer had ‘patched’ their 3 Ubuntu 18.04 nodes running Kubernetes 1.17. They were using glusterfs as their shared storage class.
