Don’t remember how many gallons your tank or pond holds? No worries, this little code below will calculate the amount of gallons the container can hold based on its dimensions you enter. Besides, knowing your actual water volume helps you determine what 10%, 30% water change means in gallons, and precise measurements of additives (conditioner, […]

My Neocaridina Water Parameters Tracker
Here’s a live water parameter history view of my fairly new neocaridina shrimp tank. For ideal parameters and more information about neos, see this post. For all shrimp-related posts to-date, click here. The top and bottom red horizontal, parallel lines indicate the rectangular area or band of a good range for the parameter in each […]
Estimating the final pH, GH, KH of your water mixture
As a fish and shrimp keeper on different tanks with different creatures requiring different water parameters and conditions, it does me good to keep track of all those especially when replacing or changing water, or adjusting parameters for optimal suitability of the creatures. For example, for the shrimp tank, keeping track of KH, GH are […]
Projecting Neocaridina Shrimp Population
Two months ago I wrote an app for myself to keep track of my new hobby Neocaridina Shrimpkeeping. It was only 2 weeks before that I started the hobby before I recognized that a handy application to keep track of my shrimp’s water parameters, treatments and care with curated, accurate information would be very useful. […]
The amazing UNDO
Sure, computers are powerful tools that allow us to create, edit, and share various types of content. However, it can also be a source of frustrations and even horror especially when we lose our work or made a mistake that ruins the creation. We may make mistakes or change our minds about what we want […]
All About NFL’s Top Heach Coaches
I dug some information on some of the 32 head coaches in NFL today, and did some analayses. I was intrigued by their performance, compensation, their roots, their network and influence, correlations among various parameters like age, experience, wins, and salary. I also looked at how many teams they’ve coached in the past, and how […]
Republican Candidates’ Primaries Spend 2024
The campaign trails are blazing for the upcoming elections and the Republican party still needs to narrow their final nominee down to one in the coming months. Niki Haley and Donald Trump are the only two remaining runners (written: Jan 25, 2024). Below are some charts I created to show how much they’ve spent on […]
How to chart ranges in Excel
Let’s say you have some actual measurements of some parameter over time or a series, and you’re measuring it to see if it falls within the “safe” or “ideal” range. How can you create a visualization to show both the measurements and the safe/idea range values effectively? That’s what I’m going to answer in this […]
Calculating Euclidean Distance in Python
Euclidean distance is the length of the line segment between two points in Euclidean space. It can be calculated from the Cartesian coordinates of the points using the Pythagorean theorem. It is a simple formula enough to be calculated by hand but powerful enough to be used in Machine Learning and Artificial Intelligence applications for […]
How to create visualizations in Excel given nested scores
Here’s the scenario:We have two players named Eve and Inna in a game competition (say, Tennis). They play 5 matches against each other, and each match is composed of 3 games called Sets.We have data on scores of the players set by set for all 5 matches.So, the question is: How do we present this […]
