Object Composition over class inheritance.
Why you should favour object composition over class inheritance. A Comparison of these object-oriented techniques and their use cases in software development.


Two definitions of Machine Learning to understand the concept.
"the field of study that gives computers the ability to learn without being explicitly programmed." By Arthur Samuel.
"A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E." by Tom Mitchell.
The term Supervised Learning refers to the process of giving data sets and the expected "right answer" to an algorithm. The task for the algorithm is then to produce a model that matches the right outputs for each data set.
In this process the algorithm learns to shape a model by comparing its outputs to the one given by a human. It is called supervised learning because the process of an algorithm learning from the training dataset can be thought of as a teacher supervising the learning process.
Supervised learning algorithms problems can be grouped into two main categories:
Unsupervised learning allows to approach problems without knowing the expected output. Algorithms derivate structure from a given data set without humans knowing how results will be. They are called unsupervised learning because there is no feedback based on the prediction results nor correct answers.

The basics of the new regulation law for user privacy and information security inside the EU.

Github announced its deprecation of user passwords for all Git operations. Git operations that use authentication will require the use of token-based (GitHub User Access Token). The motivation behind this decision from GitHub is to increase user’s security from malicious attackers.
