Java for Beginners 7 – Abstract Classes and Interfaces
The Java recognizes the limited nature of abstract classes and interfaces and their inability to become an object or a traditional class. Nevertheless, it is the absence of the qualities above and the ability to use abstract classes in various objects that proves to be incredibly useful to developers. In this article, I briefly outline the possible application of abstract classes and interfaces as well as provide examples to highlight the contrast between them.

How to remove hard returns and clean duplicate records from MySQL/MariaDB database
It happens from time to time that we have duplicate queries in our database Unique index type tables that are caused by difficult to detect carriage returns. The following method cleans up the database by first removing the hard returns, and then by removing the duplicates. [Read more…]

Java for Beginners 4 – Working with Java Loop Statements
Java recognizes three types of loops, namely ‘for,’ ‘while’ and ‘do-while’ loops that all accomplish the similar goals of iterating the block of code until a certain condition is met. The following article explores the differences between each of the loop variants and demonstrates the situations when choosing one type of loop over the other can be a benefit. There are many examples of using all three types of loops, but I’ve selected the general form and the infinite loop to illustrate the primary differences.

Polyomino Combinatorics: How to count distinct n- letter long array permutations
Let’s say we have 3 arrays of following tetromino letters: J, L, O. Tetromino J is a 4 member long array (J[0],J[1],J[2],J[3]), signifying the number of positions J block can take. L tetromino is also a 4 member long array and O is a square tetromino that has only one position (1 member long array). How do we calculate the total number of all unique n-letter long permutations, without programmatically permuting through them? [Read more…]
Java for Beginners 2 – Addressing Data Type Limitations
Java offers eight primitive data types which are not always adequate to store data of all types. There are situations when the specific data type does not fit into any of the primitive data types offered by Java. Thus it is essential to understand the boundaries and restrictions of the primitive data types in Java. In this article, I demonstrate a couple of the scenarios in which the Java data types are not sufficient enough and require substitute approach.
Java for Beginners 1 – Writing an Application Class in Java and Introduction to Dialog Boxes
Following is the first article in a series Java for Beginners that shows how to write an application class in Java and introduces the reader to dialog boxes, string to integer conversion and other basics of Java. [Read more…]
JavaScript n-Block Tangram Puzzle Solver
Recently I found a tangram puzzle made of polyomino (triominoes, tetrominoes and pentominoes) which caught my attention. The goal of the puzzle was to rotate the blocks in such a way, so they fit into the 10 x 6 rectangle box.
Ascent of Information warfare (IW) in Cyberspace
We live in a time when foreign nations no longer achieve supremacy by engaging in a traditional battlefield warfare. Most nations realized that there are considerable disadvantages to fighting the battle in the open by using the old-style weapons and mechanisms, which helped to establish an entirely new kind of combat, the information warfare. Instead of using heavy weaponry, the warfare operations are executed in secrecy primarily by leveraging the information and communication technology. As a result, the modern war has moved from a physical space into a virtual cyberspace.
VMware’s NSX™ Distributed Firewall, Intrusion Prevention and Intrusion Detection System.
The security breaches usually occur when the organization does not sufficiently restrict communication inside network perimeter or does not implement lateral security controls, which allow hackers to target the priority systems or infiltrate information. The following article talks about VMware’s NSX™ Distributed Firewall, Intrusion Preventions, and Intrusion Detection System.
Note: Article in Progress. The following is only a basic skeleton for the more comprehensive overview.
