The fastest way to read a CSV in Pandas
You have a large CSV, you’re going to be reading it in to Pandas—but every time you load it, you have to wait for the CSV to load. And that slows down your development feedback loop, and might meaningfully slows down your production processing. In this post, learn the fastest way to read a CSV in to Pandas.

Create Gorgeous Maps with Prettymaps + Python

Learn how to make gorgeous maps of anywhere in the world in just a few minutes. Prettymaps is a Python library that takes data from OpenStreetMap and crafts it into great little maps where you have a lot of control over how things are displayed. In this video, we’ll take a look at how to run Prettymaps, how to create circular and square maps, maps of any area defined in OSM, and maps with sets of adjacent areas, such as parts of a town altogether.

How to Set Up Source Maps with Django
Source maps are files that map your minified CSS or JavaScript back to the original code. They allow you to use your browser’s development tools to debug minified code as if it were the original. Also, some error capture tools, such as Sentry, can use source maps to report errors for the original code. In this post, we’ll look at how source maps fit into Django’s static files infrastructure, including a couple of recent changes I made to Django to better support them. We’ll look at using a JavaScript source map, but everything applies equally to CSS source maps.

FastAPI and cooperative multi-threading
Cal Paterson wrote a great article comparing and describing synchronous and asynchronous Python frameworks and explaining why asynchronous frameworks go a bit wobbly under load. This is a story of how we experienced wobbliness in a recent project.

Monitor Amazon S3 activity using S3 server access logs and Pandas in Python
This post shows you how to use Pandas in Python to analyze Amazon S3 server access logs for a couple of common customer use cases: monitoring a static website and monitoring S3 Lifecycle activity. With the outlined solution, you can simplify yet augment your data monitoring and control at scale to optimize for cost, security, compliance, and more.
