The application’s action clip is below: In the above clip, I’m reading datafiles that contain the coordinates as a series of contiguous […]
Scattered Data to a Butterfly, or a Tornado!

Using Python, SQL, and Excel together for data shaping & analysis
There are times when I’d like to take a peek at my data CSV or XLS/X even before firing up Excel. Usually when the dataset is large and I want to quickly inspect it and modify it for my needs before even putting Excel to work. For that purpose, Python is very useful. Add its […]
“God” game—revisited (aka Pop game)
What seems like yonks ago, I wrote a fun, DOS based visual game in college that’s a simple simulation of population growth with some user-inputs to the game (i.e. playing “God”, hence the title). You can read about it here. But here, I’m sharing info about that game, revisited, with a different twist. I rewrote […]
Data extraction with multiple criteria with interactive UI
Imagine we are business owners who provide a range of services. We have a large set of customer data but we really want to target those customers who might be interested in your services. We want to extract only that subset of data based on our services. And since we provide multiple, diverse services the […]
