I had heard before that Go dominates as the programming language of the cloud and wanted to investigate that claim. In this post I looked at the repositories of all Cloud Native Computing Foundation (CNCF) projects and assembled statistics on the programming languages used.

When I first dealt with consuming Protobuf messages in Apache Flink it took me some time to get everything working. In this post we will go over a simple example from a project I worked on that demonstrates how to consume Protobuf messages in Apache Flink.

The following is a collection of Linux observability tool diagrams that I have collected and keep close by for reference. They primarily come from the blog posts or books of Brendan Gregg.

My Sirius XM now playing tracker has been running for six years without any major interruptions. Today I gathered all the data collected to date and am open sourcing the dataset for anyone to use.

Often we need to run shell commands on a running docker container. The traditional way would be to run docker exec -it <container> /bin/bash for example. Below is an alias to simplify this process a bit.

Some Kubernetes resources require elevated privileges to access. For example, passing --as <namespace>-admin to each kubectl command. Below is a convenient alias to elevate your permissions for such resources.

Described below is a convenient way to configure and switch awscli between multiple AWS accounts.

If you are like me, you may have an old, but still perfectly functioning printer which you would like to print on from anywhere in your house.

Apache Pulsar is a distributed pub-sub messaging system that I have recently enjoyed testing for some projects of mine. It has grown very much on me and am now preferring it over Apache Kafka. In this post we will go over installing and getting started with an Apache Pulsar instance running on Kubernetes.

A while back I needed to identify time windows within a time series dataset which led me to discover some interesting SQL functions I was not aware of. In short, what I refer to as a window is a start and end timestamp during which certain defined conditions were true. This post will explore a bit more of the problem definition and go over an example SQL query to tackle it.
