Let’s Roll! — 2 dice…and find the probability and chart it (Python)

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 2

This is part 2 of the original series on Rabid Racoon. Please read Part 1 first to follow along. So, this time we’ll use a real-time graphing method using Python’s Turtle library instead of scatter plot as we did in Part 1. The beautiful part is, since we already created our custom Class in Part […]

“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 […]

Fun riddle…let’s solve it together

There are 50 horses and 50 kings riding along an old dirt road. (We still have Kings? WTH?!)  They came to a peach tree with 50 peaches (peach tree grows well somewhere I guess!). Each took one, yet there were still 49 left. How is this possible? Well, capitalization may be of importance, or not. […]

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. […]

Editing Registry using C/C++

WARNING: This is a real easy one, but can be dangerous! Do NOT use this for any malicious or system purposes unless you have been instructed to do so from a verified support professional! This is NOT intended to be anything other than for a test and education. I’ve written millions of lines of code […]

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 […]
