Functional programming. Part I:
The essence of functional programming: Theoretical basis
When writing about functional programming, it is better to start from recalling programming types in general. There are two broad categories: imperative and declarative. Continue reading
An IP address conflict occurs when two computers in a network are assigned the same IP address. When this happens, it renders one or both computers unable to connect to a network resource or perform other network operations.

Python Graphics With Turtle
The turtle module in Python is a very simple tool for creating various objects and animations. The idea behind this name is based on real life: a turtle can go forward, backward, right, or left, and when doing so it leaves a trail. It is possible to command a turtle to take up its tail, though no footprint will be visible. In fact, these two sentences explain how everything works here, so let’s see how far we can get. Continue reading
Java Web: Servlets, JSP, MySQL
In this sample, we present a program using servlets, Java Server Pages (JSPs), and a connection to the MySQL database. The database is called “Student” and has one table with the same name. The program in Java allows us to add a new student, delete an old student, and update existing ones, and shows all students that are in the database. Continue reading
