In this post, I share a program that is built with an object-oriented design from the ground up in Python. It’s a game or simulation if you will, but has all the plumbing necessary to make it fancier, and a 2D or even a 3D game. It works as follows:You create a car object. Then […]

Etch-a-sketch using Pygame
In one of my past posts, I demonstrated an Etch-a-sketch program using Python’s Turtle library. In this post, I demonstrate writing a similar app using pygame library with new twists. The idea is similar…you use up/down/right/left arrow keys on your keyboard to move the drawing cursor…however, you can also press up+right to make it go […]
True text transformation without using any special libraries (Python)
In this post, I’ll share a real example (and an application that you can download and use for your personal use) on how to turn text into fun representation such as: flipped, reversed, substituted with other characters using Python. The output is not an image, but still real text that are not easily accessible from […]
Geometric Shapes with Tkinter & Turtle
In this post, I’m sharing a complete Python program that draws various geometric shapes on screen with given parameters (e.g. side length, radius, height, tilt, etc.). The application is downloadable here and can be executed on a Windows device (tested on Windows 10). The download will be a ZIP file called tkinter-drawgeometricshapes.zip —copy or unzip […]
Network graphs explained with scenarios (Python) – Part 2
This is Part 2 of the series “Network graphs explained with scenarios“. Please read Part 1 first for proper continuity. A few of the scenarios I cover in this blog series here: Project scheduling example – Shows how to compute critical path on a network of related tasks. Covered in Part 1.Routing example – Shows […]
Network graphs explained with scenarios (Python) – Part 1
Network graphs are quite fascinating to me. They are all around us and used daily in a multitude of real-world applications from supply-chain, routing, mapping, social media, scheduling, to networking. In this two-part blog series, I’ll go over some real-world applications of graphs and how to generate them dynamically using Python. There are many complex […]
Complementary post to: Pop Quiz [And Solutions With Low Code!]
This post is a continuation of or complementary post to about using Excel and SQL for pop-quizes. Please read that first to get proper context…otherwise, this wouldn’t make much sense. As discussed in the post linked above, the SQL queries can be saved from Microsoft Query Editor to an external file. It’s really convenient because […]
Pop Quiz [and Solutions with Low Code!]
Every now and then I see some simple quizzes pop-up on Facebook such as: “Name a state without letter A in it.” The letter can be another, they just switch it around from time to time. This particular post is inspired by such posts. Sure we can go through all the states in our heads […]
BACTERIAL GROWTH SIMULATION (Binary Fission)
Here, I present a quick simulation application (runs in the browser) of population growth of bacteria that mutiplies following binary fission reproduction. Basically, it’s the division of a single cell into two or more cell and the regeneration of those parts to separate cells resembling the original. To play the simulation, just navigate to the […]
My SW Projects – a subset of many
This page is a single, nifty starting point for various projects (apps, utilities, research tools, games, etc.) I developed for desktop, webapps, and mobile devices for intellectual curiousity and fun. They are free, and ad-free. No gimmicks. These will run on any modern smartphone, tablet, PC (see each description below as some are made to […]
