Recently I had to do a design for a system that had a requirement to search strings in a big unstructured data source. While doing research, I learned about a neat data structure, that is perfect for the use case. Enter Trie!

Feature flags (or feature toggles) are an approach in software development used to enable or disable features and code within the application without the need for a new deployment. They are typically implemented as a simple conditional if-else statements but various tools exit to support managing the flags.

Overview # With the prevalence of microservices today, it is important to define how the interaction between the different components of an application happen. When you have a monolith application that is easy - the method signatures and interfaces define a rigid structure and any errors due to changes are caught immediately at the build/compile step. For microservices, we don’t have such an enforcement of correct communication - any error surface during integration testing which is often too late and slows down development.

I recently had a problem with Homebrew on my Mac. When I tried to install something, for example brew install docker it will freeze on the command Running brew update --preinstall. Apparently there is a way to debug what happens by running brew update -d which will output the log of the update command. On my Mac it will block on rm -f /opt/homebrew/.git/TMP_FETCH_FAILURE (that is for M1 Mac, on Intel the path may be different).

Colima is a simple way to run Docker or Kubernetes locally on your Mac. It is very light and takes little resources on my M1 machine.

This post contains a brief overview of the terms and mechanisms of Kafka. Reading this won’t make you a Kafka expert, but it will allow you to grasp the basic concepts. Overview # Apache Kafka is publish/subscribe messaging software designed to handle communication between different systems. It is often described as distributed event streaming platform, and it is used to implement event-driven architectures. Its benefits are very high performance, reliability and message retention.
