Using GPT-3 to explain how code works

One of my favourite uses for the GPT-3 AI language model is generating explanations of how code works. It’s shockingly effective at this: its training set clearly include a vast amount of source code.

How To Use Docker To Make Local Development A Breeze 

Docker is a very powerful tool for developing applications that run in the cloud. If you want to get the most out of it, you need to make sure that the way you're running your code locally matches as closely as possible with how it runs in the cloud. This video shows you how to do this, using a simple API server in Python as an example. 

I analyzed 1835 hospital price lists so you didn't have to

The current law requires that hospitals code their procedures with a generic code. This way you can compare prices between hospitals. Of the 33% (or so) of hospitals that publish their chargemasters, and are in principle in compliance with the law, many of these hospitals only publish partial information, making price shopping a lot like mattress shopping. Our goal is to clean this real-world dataset and see if we can figure out how many rows can contain a code. Then we'll see how many hospitals are following the law.

Evaluating Mechanical Keyboard Delivery Estimates with Python Web Scraping

Extract Text from Images with Python 

In this video we learn how to extract text from images using python. We compare three popular libraries: pytesseract, easyocr, and keras_ocr. Examples are run in a kaggle notebook on the TextOCR dataset.
