The name of this blog was born as a tribute to an article by Steve Blank (In a Crisis – An Opportunity For A More Meaningful Life), and more generally to the concept of Lean Startup proposed by Eric Ries.

The Build-Measure-Learn cycle is deliberately inspired by the scientific method and is the basis of the Lean Startup concept. Despite its scientific origins, the Build-Measure-Learn cycle is applicable in many other fields and on ourselves as well.

Most of this website is a living document. Hopefully, it will help some people to learn to code. More material will be available gradually.

At the moment, you can find some material regarding RxJS, an Angular tutorial, some posts on React, and some small web development guides. Since I am still thinking of a good way to show these things, you may need to search them in the menu on the top-right corner, under TECH.

Lately, most of the focus is on Angular and RxJS. So, if you are interested in learning to code using Angular, I hope you will find the Angular tutorial useful.
