I’ve set up TensorFlow on dozens of machines — fresh Windows laptops, Ubuntu servers, and M1/M2 Macs — and I can tell you that most people who run into trouble aren’t doing anything dramatically wrong. They’re just using the wrong Python version, skipping the virtual environment step, or following a guide that’s two years out … Read more >>
As a Python developer, I often work with screenshots, product images, blog images, and photographs that need to be uploaded to websites or shared online. Large image files can slow down websites, consume storage, and make file sharing inconvenient. To solve this problem, I built an Image Compressor using Python and Streamlit. This tool allows … Read more >>
As a Python developer, I often work with large PDF files. Many times, I only needed specific chapters or selected page ranges, not the entire file. One day, I had a 900+ page PDF and needed to send only a few pages separately. Manually extracting pages using online tools was frustrating. That’s when I decided … Read more >>
As a Python developer, I often work with PDF files that contain confidential information. Many times, I needed to share PDFs securely with clients or team members, but I wanted to restrict unauthorized access. Instead of using online tools, I decided to build my own Add Password to PDF Tool using Python and Streamlit. This … Read more >>
In my years of developing React applications, testing has always been the backbone of a reliable product. One tool I find myself reaching for constantly is jest.spyOn(). It is incredibly useful when you want to track how a component interacts with its dependencies without completely replacing them. In this tutorial, I’ll share how I use … Read more >>
As a React developer with over eight years of experience, I’ve seen firsthand how testing can make or break the quality of an application. When I first started writing tests for React components, it felt overwhelming. But once I got the hang of Jest, the popular testing framework, and combined it with React Testing Library, … Read more >>
You can get the week number from a date in TypeScript with a short function: move the date to the Thursday of its week, then count 7-day blocks from January 1. That gives the ISO 8601 week, where weeks start on Monday: JavaScript’s Date has no built-in week method, so I wrote and compiled every … Read more >>
Recently, I was working on a project that required me to extract the day of the month from a date in TypeScript. This is a common requirement when building date-related features like calendars, scheduling applications, or any system that needs to parse dates. In this tutorial, I will show you several methods to extract the … Read more >>
As a Python developer with over a decade of experience, I’ve worked extensively with machine learning models. Among them, logistic regression remains one of the most useful yet simple algorithms for classification problems. In this article, I’ll walk you through how to implement logistic regression using Scikit-learn, the go-to Python library for machine learning. I’ll … Read more >>
As a Python developer with over a decade of experience, I’ve seen firsthand how essential Gradient Descent is in machine learning. Whether you’re tweaking linear regression models or diving into neural networks, understanding Gradient Descent can dramatically improve your model’s performance. In this article, I’ll walk you through how to use Gradient Descent with Scikit-Learn, … Read more >>
