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…]

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.

How to fix Windows 7 RDP resolution limit of 3840×2048 on 4K (3840×2160) monitors? (also applicable for Win Server 2008 R2)

One of the issues of Windows 7 (and Windows Server 2008 R2) is related to its inability to support 4K resolutions over RDP. Windows 7 RDP resolution is limited at 3840 x 2048, whereas 4K monitors run at 3840 x 2160, which leaves a small black strip at the top and bottom of the remote desktop window. The following article describes the way I was able to resolve this issue. [Read more…]
