What numbers will you get if you roll 2 dice? How about we find out by writing a program? Can we then chart the results over as many rolls as we want? And then interactively play with the chart? Asking a lot! But yes, I will do ALL of the above here. Better yet, why […]

Draw A Beautiful Gradient Scatter Plot (Python)
In this demo, I’ll draw a beautiful, elegant, gradient-colored (themed) scatter plot using some data for x and y axis. The neat thing I want to demo here is not so much the data themselves, but how to apply a “colormap” to the graph using Python’s matplotlib library. Specifically, its pyplot module. What’s Desired: The […]
“Rabid Racoon” tracking (Python, using our own class)- Part 1
Just like most high-level programming languages, Python also supports the idea of classes. Once the class(es) is/are created they can be inside the main python file or separated (in most usage scenarios), along with it methods. For Python-specific syntax, please refer to its documentation online or offline (python.org is a good start), but you should […]
How do those words game work???
Here I’ll show you the basic concepts of the most famous word games…and how they are actually coded. Obviously, I’m NOT going to show you advanced algorithms or any proprietary information here. Just the basics…you go party on with this information with your own creativity. There are numerous games out there based on this concept. […]
You Won’t Believe This! (Zen of Python)
If you just want to know what programming principles the founders of Python wanted you to stick with, there’s a simple code to expose them all! Add the following code to your python shell:

import this |
Yep. One line of code. What do we get? Beautiful is better than ugly. Explicit is better than implicit. Simple […]
How to change keyboard strokes (C/C++) Part 2/2
This is part 2. Please refer to the part 1 for context. In the following simple C program, I’ll demonstrate how to capture keystrokes and turn them into something completely different…other than what the key labels read. This is the basic idea behind changing keyboards from English to another language; take the input from the […]
How to change keyboard strokes (C/C++) Part 1/2
In the following simple C program, I’ll demonstrate how to capture keystrokes and turn them into something completely different…other than what the key labels read. This is the basic idea behind changing keyboards from English to another language; take the input from the key, read its character code (ordinal value) from the operating system, and […]
Digit To Word And Vice Versa (Python)
How can we convert in a program from words like “eight” to the number 8? How can we convert the number 10 to the letters “Ten”? Here, I show you multiple ways to do it bi-directionally…from letters to digits, and digit to letters. I’ve seen several implementations and many rely on ASCII ordinals. But I […]
Let’s Play Palindrome! (C/C++)
Did you know that the longest Palindromic word in the Oxford English Dictionary is “tattarrattat” coined by James Joyce in Ulysses (1922) meaning “a knock on the door”? What is a Palindrome, you ask? Well, you already know it or have seen it. According to Wikipedia: “A palindrome is a word, phrase, number, or other […]
