Linear algebra

My Linear Algebra notes accompanied with related studies using Python functions written by me to automate some types of calculations and exercises. These functions mainly leverage the SymPy library (for symbolic mathematics, for the linear systems and combinations), along with Nu...

This type of analysis can help to develop competitive schemes without weaknesses, that is, they do not expose fixed pre-built strategies that allow you to circumvent the logic coming to the end result without depending on the results of other players.

A ML model can be trained to predict the right...

Gradle is considered to be a build script language. Maven hides the build logics inside plugins, so it would be necessary to build up an own plugin in order to generate the particular build logics.

The build script is an actual programming language, and not a series of XML tags as happens in Mav...

It logs and produces a txt report containing the list of files based on a date (by default datetime(2021, 2, 1)) and a byte size (by default 47185920)....

The Interface Segregation Principle (ISP) states that a client should not be exposed to methods it doesn’t need. Declaring methods in an interface that the client doesn’t need pollutes the interface and leads to a “bulky” or “fat” interface.

Let’s look at an example to understand why the Interface Se...

I wrote this shader in 2019 to generate large scale cities inside QBatica. It is expected to be used in pairs with Instancing Shader. It was made to be applied to the terrain plane to tweak the map on which the buildings blocks are arreanged; it is implemented at the fragment and the tessella...
