Hello everyone 👋, This is my first blog post about AI, it’s a quick post on how to enable GPU support for the FastAI library. I have avoided getting into AI for some time now, I thought that it would involve lots of complicated math, and I was not sure that it would be worth the effort, I did not get very good grates in my college math classes 😅. ...
Hello everyone! 👋 In this article we’ll talk about documentation and how to document a Python project with pdoc. Documentation is an essential part of writing high-quality Python code. Not only does it make your code easier to understand, but it also makes it more maintainable and reusable. In this post, we’ll explore how to use pdoc to generate documentation for your Python code. pdoc is a powerful tool that can automatically generate documentation for your Python modules and classes based on their docstrings. Docstrings are special strings that appear at the beginning of a module, function, or class definition, and provide a description of the object’s purpose, parameters, return values, and other relevant information. ...

Introduction Hello everyone! 👋 I’ve been practicing with some Leetcode daily challenges lately and since I’ve recently moved to Substack I wanted to make my first post here 😁 Boats to Save People The problem Boats to Save People is solved using a Greedy approach. Given a number of people and their weights, along with a carry limit for the boat. You must find the number of boats needed to carry the people. A boat can carry a maximum of two people at a time. ...
Hello 👋, In this short article we’ll talk about packing integers into binary data in JavaScript using the Buffer, ArrayBuffer and DataView classes. Sometimes in JavaScript, it may be necessary to pack the elements of an array into a byte buffer and then create a new numeric array from the buffer’s contents. This can be achieved using the DataView object in JavaScript. First, create an array of elements you want to pack, for example: ...

Hello 👋, In this short article I want to talk about parallel processing in Python. Introduction Sometimes you will need to process certain things in parallel. If you’re using Python you may know about the global interpreter lock abbreviated GIL for short. The GIL is a lock that allows only a single thread to control the Python Interpreter at a time (per process), that means that your multi-threaded Python program will have only a single thread executing code at the same time. ...

Hello 👋 In this short article I will show you how to split audio from video using ffmpeg. When I worked on my Udemy course I needed a way to process audio in Audacity and edit the video in Kdenlive. So I wrote two bash scripts, one for spliting audio and video and another one to combine the processed audio (usually a .wav file with the same name) with the video. The result is the following ...
