I started a project that visas to teach teenagers to computer programming. During the planning of this project, we discuss several things, mainly the technology for implementing the algorithms. Some people mentioned the language Python, while other playful tools such as the scratch. However, the language chosen was the C language. The fact that we […]
Nowadays, it is still common to find software systems designed with a monolithic architecture, mainly the legacy systems, even with the popularization of the Model View Control (MVC). The development of systems based on MVC, introduced by Trygve Reenskaug into Smalltalk-79, is a software design pattern, which the components of the software are organized in three layers, […]
Undoubtedly, data are the fuel of the current economy when they are transformed into reliable information. Who is responsible for such transformations? The responsible are Data Engineer, Data Analyst, Business Analyst, and Data Scientist. What do they do for it? The Data Engineer integrates data sources, building data pipelines, processing and transforms data, and stores […]
Before thinking about some Artificial Intelligence (IA) technique for applying in Competitive Intelligence (CI) is necessary to know the Business Planning (BP) of an organization where the CI will be implemented. Even using an approach as the CIbD, ignore the BP facets and their stakeholders can lead CI projects to failure. Business Analytics (BA) can […]
The algorithm is the base of computer programming. Therefore, is necessary to have a good understanding of the concept and elements that featuring an algorithm. The use of the algorithms is ancient and history shows that algorithms were used by Babylonian Mathematicians, about 2500 BC (more about). In the 50s, the word algorithm was most […]
Python is an interpreted, object-oriented, high-level, and multi-paradigm programming language. Python is a general-purpose programming language created in 1991 by Guido van Rossum as a successor to his previous language ABC. For data analysis and interactive, exploratory computing, data visualization, and other data science operations, Python has been widely used. However, there are gaps that […]
