In this tutorial, we’ll implement a Naive Bayes spam filter that not only classifies emails but also includes testing functionality and the ability to update its knowledge base with new data. Overview Our implementation will include: Implementation Here’s the complete implementation of our advanced Naive
This tutorial walks through implementing linear regression from scratch in Python, without using machine learning libraries like scikit-learn. We’ll cover the math behind linear regression, implement core functionality, and demonstrate usage with real data. Overview Our implementation will include: Implementation Let’s start by implementing the
In this post, we’ll explore how to implement basic calculus operations on polynomials using Python. We’ll cover derivatives, polynomial evaluation, and numerical integration, with clear examples and explanations along the way. Representing Polynomials in Python We’ll represent polynomials as lists of coefficients, where the index
Hello, I wanted to try these ST7735 inexpensive displays that can be found all over the internet, so I ordered a couple for a few euros each. My quick research showed that a number of libraries support them and it turns out that you can

Sometimes you may get an error message “ECONNREFUSED 127.0.0.1:8080” especially if you are having many bash terminals open and you spin multiple webservers. So if you just want to find and kill the process on the x port that is causing the trouble, in this
A few years ago there were very little resources to those who wanted to start a career in development. You either had to graduate from a university or reading books. Today there are many free online courses available to anyone. The quality is really high due
The title of the article is pretty much self-explanatory. So the easiest way I found to drop all your MongoDB databases from mongo CLI is to run this simple command which actually what it does is it goes through the result of getDBNames function and
If you are like me who today tried to start mongod and got the error below [initandlisten] ERROR: listen(): bind() failed errno:48 Address already in use for socket: 0.0.0.0:27017 [initandlisten] ERROR: addr already in use [initandlisten] now exiting Then what have to do instead of restarting
