rust
A couple weeks ago I gave a talk to the BCNRust meetup group about Leptos, a web framework I have several posts about. Everything there was actually a demo powered by this library, with interactive pages, real-time polls and public collaboration. Additionally, Grzegorz explains some Leptos optomizations to power his

Those last months I decided to learn this new fancy and hipster language, so let me share a couple of links I would now recommend. I'm coming from mostly python, but a bit of functional experience with scala, so I'm comfortable with the typing system (and

Leptos is a production-ready full stack server written in rust that brings component reactivity, server functions and rust's type safety without needing to know Javascript

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.

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

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.
python
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.
Spark
How to use one of the best AI/ML libraries (hugginface) with Spark? Let's try it

Some pictures taken in Scotland. Use them as you please under CC BY-NC-SA and if used in public (blog, presentation , news article...), cite me or this web/post. Can't be used to train AI/ML algorithms.
Spark
The pyspark library communicates to a spark driver. If the driver dies, we'll obtain some odd error messages that will not directly indicate the root cause.
