## Splitting a continuous blob of text

There are times we copy a bunch of text from a web page or a trascript online where formatting is not copied and therefore everything copied comes in the clipboard as a large continuous text blob without line breaks. We often need to split a continous series of sentences into their individual lines for better […]

## Companion Code Handbook for Hello Arduino! Published

Greetings readers. I have just published (live on Feb 10th) the paperbook book: Companion Code Handbook: Hello Arduino! This companion book is a handy reference with complete source code with comments for all projects detailed in the book Hello Arduino! This is a printed version of all source code required for completing all projects (and […]

## How is chatGPT useful?

Author’s note: Instead of me explaining the benefits of ChatGPT, I figured why not let ChatGPT write its own summary and toot its own horn, and best of all write it straight into my blog site, creating a real blog post (without having me to copy/paste) and go live?! So, there we have it…this post […]

## Decision Tree and Prediction (Python)

This is an example of a Decision Tree model (very useful and popular method) to make prediction using the power of Machine Learning…using just a normal PC. Here we predict salary (depedendent variable) by giving various types of criteria (different forks in a decision tree). e.g. What’s the salary of a particular gender, of some […]

## Wanna be a weather reporter? Me neither! So let’s do Machine Learning (AI)! Part 2/2

This is a continuation of weather prediction via ML and is the final part (2/2) where I demonstrate how to write Python code to leverage a neural network algorithm called Neural Prophet, a quite straight-forward and useful model. Be sure to read the first part that focuses on understanding the data in Excel and some […]

## Wanna be a weather reporter? Me neither! So let’s do Machine Learning (AI)! Part 1/2

Reporting weather by reading off the predictions is obviously a very different skill than creating the code and models that actually predicts the weather! Not just forecasting for the next 5 days, but actually PREDICTING for any number of period in the future! Is that even possible? Yes, it is albeit there are myriad of […]

## Creating music and teaching coding

Have you heard of Earsketch? It’s an amazing, fun way to create music while learning, practicing, teaching coding! Yes, music and coding all in one with its online, free platform (for students)…you just need a browser. It supports Python and Javascript coding in their online editor and you can compile and run the code on […]

## Machine Learning in Python (Univariate Linear Regression)

In this post, I share a method to utilize Machine Learning using Python. I have collected some data from CDC site about birth rate in the USA over several years. What I’d like to show you is how we can predict birth rate for a year that is NOT present in the dataset. For example, […]

## Make a computer guess your word – Python

You’ve undoutedly played games like hangman or seen TV games such as Wheel of Fortune where you’re supposed to guess a word by only given the number of letters (or their placeholders, blank tiles) in a given number of tries. You may have also written similar games yourself. In this post however, I’m going to […]

## Share variables across different modules – Python

There are several ways we can share a variable’s value or multiple variables’ values set across different modules or code files. One of the easiest and efficient way is taking advantage of config module in Python. In this post, I demonstrate exactly how it’s done. Imagine the scenario where you have a python module that […]
