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 […]

Combining multiple datasets into a single data file (Excel or CSV)
The Scenario I want to analyze data for New England Patriots over the past 10 seasons. The data files are downloaded as a file by year. So, for 2010 through 2019 NFL season, I have 10 separate data files. I need to combine them all into a single file so I can do an all-up […]

Using Python, SQL, and Excel together for data shaping & analysis

Generating, plotting trajectory and…gamification (Excel)
Reminiscing the old tank game, I wanted to re-create a low-weight, low-code option of that simulation. The game depended on a canon (projectile) shot at your selected speed and angle to hit an enemy tank. The foundational formula is used in missile launch, sports, and many (you guessed it) military applications. Here, using the same […]
Phone number formatting tips (Excel and Python)

Today, I show different ways to format an un-formatted string that contains phone numbers using Python, and Excel. Our task is to format it (either for human-reporting, or consumption by […]

So, let’s start with the set up details: You’ll need to install the following packages IN ORDER: 1) beautifulsoup4 2) google NOTE: The package to […]
The 3n+1 Problem & More! (Part 2)
This is a continuation (part 2) of my blog titled The 3n+1 Problem & More! I recommend you read that first to get the context, or it’ll be really boring or at least confusing 🙂 In the previous blog we generated a sequence of numbers starting from ANY number and converging to 1…always! I also […]
The Dictionary Challenge-Part 2
This is a continuation of the Dictionary Challenge previously completed. To follow along, you should read that post here. So, we have already downloaded a free Webster dictionary but completely unformatted and unstructured. So, we created a new file in a more structured way that our program can process. The code is in the previous […]
The Dictionary Challenge-Part 1
Ok, today I’m inflicting a self-imposed challenge…here it is: Get an English dictionary. Then find how many words start with vowels. How many words are there starting with “odd” letters, which I’ll set as: Z, Q, J. Then find the longest word in that dictionary. (Say, we’re going to make a word guessing game) All […]
