After a few years, taking plenty of courses about data science and more, I have made the following discoveries which may seem trivial, but let me explain also where I come from: I am a developer and I know several programming languages and tools I tend to forget things that I do not use frequently …
You have a distance sensor HC-SR04 and a series of distance observations, assuming the target does not move you want to establish the best or most correct measure. The particular sensor used is a HC-SR04, of which an analysis of the accuracy and performances is presented here: in the analysis, as I do not have any specific …

What you learn during your lifetime will hopefully stay with you for the rest of your life. However, if you do not use the skills you have learned, they will get rusty, and if you do not sharpen them from time to time, you will find that they will be not any more readily usable …
Let’s go to the point: Finally Python has what R used to have since a looong time ago with Shiny. This is nothing less than Python Dash, a Python framework for building analytical applications (in the author’s own words). The library is based around Flask and Plotly, the installation is pretty easy and it is …
I have found out a couple of days ago that the evolution of the libraries in the Python ecosystem is FAST. It is not only fast, it is exceptionally fast. In my opinion some of these libraries are evolving together with the market and mainly for market reasons (one of these libraries is Pandas, part …
I have already written an article about using a SQLite database from R. I was playing recently with some data, scraped from a web site to text files, that I wanted to transform into a SQLite database. I decided to do it in python, using the sqlite3 module. After a few experiments, I noticed that …
Now something different! Well, besides trying to learn as much as possible about Data Science, Machine Learning, Big Data etc, a few weeks ago I was brutally deviated to other subjects, by being asked the following question by my fourteen years old son: “Dad, can you teach me some programming”? At that point a number …
This resource is totally free, and consists in a course based on a book which is itself totally free and available. I got to know it while browsing the forums discussions on Coursera Data Science Discussions. Somebody in a discussion compared this course to the Machine Learning Course by Andrew Ng, and added that this …
