Data Concept: Idempotence

Idempotentity is not only useful in the design of data pipelines, but also as a system-wide concern, since if one step is not idempotent, the entire quality of the results will be affected. Let's look at a practical example.

Diagrams as Code in your blog with Mermaid

So the people that know me might remember that I have a sort of obsession with diagrams. It helps me think and evolve my thoughts. I also love how git works and the importance of having code that can see its changes across time. So it's no surprise

SQL + DataOps = SQLMesh?

DBT is valuable but lacking. SQLMesh promises enhancements like unit tests, environments, airflow support, change plans, and CI/CD automation, providing a better development experience. Let's see its features.

Dangers of recursion (python vs rust): Fibonacci case

Fibonacci sequence is commonly used to show recursion, but may not be the best algorithm to compare languages and performance, since the recursive implementation is not the optimal one and languages like python will outperform rust or C.

Grid neighbour operations in Spark

In physics or biology you sometimes simulate processes in a 2 dimensional lattice, or discrete space. In those cases you usually compute some local interactions of "cells", and with that, calculate a result. An example of this could be the Ising model which was proposed in 1920 for
