CAP theorem is a fundamental principle in distributed database systems that states only two out of the three: consistency, availability, and partition tolerance, can be achieved at any given time.

In my current project, we use Kubernetes massively and with that, I needed to perform tests more than once to verify that my deployment file was correct. Although there are environments that I could use to test, I decided to use minikube, in order to carry out tests locally and not risk impacting other users/applications.

A reverse proxy is a server that has as its main functionality to receive requests from an external network, usually the Internet, and forward them to servers on an internal network.

Building tests is surely one of the most difficult and time-consuming tasks for a developer, in addition to usually generating more lines of code than the added functionality. This is due to the various scenarios that need, or should, be verified.

Recently, I had to transfer my private keys to a different computer. Since this looks like a trivial task (it was my first time doing it), I have decided to search for a “how-to” blog post that details the steps required for this task. After a few minutes, I got shocked that it seems to be a task that people don’t usually do, they seem to transfer only one key at once, never the whole key-ring.
