I’m sure everybody who worked with Python and a PostgreSQL database is familiar or definitely heard about the psycopg2 library. It is the most popular PostgreSQL database adapter for the Python programming language. In my work, I come in contact with this library every day and execute hundreds of automated statements.

Overview Lately, I worked a lot with the Azure Cloud. Overall I have to say Azure offers a lot but is still not on the same level as its hardest competitors (AWS, Google). One thing that caught my eye is the compatibility of certain programming languages. Azure supports a few different languages (C#, JavaScript, Java, Python, etc.) but the supported features for these languages differ a lot. I think Azure Cloud is really great for...
  Support Vector Machine (SVM) is a widely used supervised learning algorithm for classification and regression tasks. It is mostly exploited for classification problems. The points of different classes are separated by a hyperplane, and this hyperplane must be chosen in such a way that the distances from it to the nearest data points on each side should be maximal. Support Vector Machine has some advantages. The first one is that SVM...
