Pseudo-random numbers in C Pseudo-random numbers in C: Introduction: In Ancient Greek, the adjective: ψευδής [1] . or, when transliterated: ‘pseudḗs’ means: ‘lying,’ ‘false,’ ‘fictitious,’ ‘sham’ [2] . . A classical computer is a deterministic machine, and, in and of itself, cannot generate a truly random number.  A classical computer, in and of itself, can only generate a pseudo-random number. [3] . A pseudo-random number is not a true random number – its having been g...

Definition Lists in HTML 5 Definition Lists in HTML 5:      Figure 1:   An HTML 5 logo that I designed in SVG      Figure 2:   the SVG image, in  Figure 1:   when exported as a .PNG file. There are three types of list elements employed in HTML 5.  These are: Ordered Lists; Unordered Lists; Definition Lists. Below is an example of a definition list.  I took the definition of the mathematical term: ...

Provinces of Ireland Nested Unordered List Example      Figure 1:   A Flag of Ireland  that I scripted in SVG. This is the flag-of-Ireland image exported as a PNG file.      Figure 2:   Above is the flag-...

     Figure 1:   A Venn diagram that illustrates how information, or data is grouped as regards Structured Query Language. How information is grouped together within programming languages is an important concept to grasp.  I find that the drawing of Venn diagrams assists me with this.

My first X3DOM page Hello, Cube!      Figure 1:   It is possible to script Three-dimensional objects with X3DOM.  X3DOM follows the declarative scripting paradigm of two-dimensional SVG as opposed to following the programming imperative paradigm of JavaScript and Canvas. This is my first html page that includes a three-dimensional object. X3DOM is a Javascript library that allows one to code three-dimensional objects - such as cubes, speheres, cylinders, etc. - with tags, just as SVG allows one to do with two dimensional objects - squares, circles etc. You can manipulate the below cube with your finger - should you be employing a touchscreen - or with your mouse cursor - should you be employing a desktop. Should you use two fingers on a touch-screen device, then you can scale the size of the cube in real time. Holding one's two fingers to the screen...

Mistakes in SVG Constructive Mistakes in SVG: I was trying to code a Bishop’s mitre in SVG, but I made a mistake in the code... however, with art, mistakes are serendipitous and an impetus to further creativity. So I ended up with this creepy-looking gravestone instead. You can code HTML-5 game graphics in SVG, and I always love creepy graveyards in games. Requiēscat in Pāce Figure 1:   The resulting Gravestone image. Figure 2:   What the image looks like when exported as a PNG. You can locate the source code of this gravestone image at my Codepen Account. Figure 3: There is usually a graveyard in The Legend of Zelda titles! You c...
