In this video, we adapt a clumsy, non-Pythonic API into an easy to use, easy to understand Pythonic one. We use magic methods such as _getitem__, __len__, __enter__, and __exit_ to make our objects a context manager and support the len() function and square bracket indexing. And in the end, we turn what once was ugly, difficult to maintain code into something that other developers would actually want to use.

Instagram has introduced Immortal Objects – PEP-683 – to Python. Now, objects can bypass reference count checks and live throughout the entire execution of the runtime, unlocking exciting avenues for true parallelism.

A deep dive into using indentation-based languages like Python and Slim, to build beautiful websites and love the work of doing it till the end.

This course from Harvard University explores the concepts and algorithms at the foundation of modern artificial intelligence, diving into the ideas that give rise to technologies like large language models, game-playing engines, handwriting recognition, and machine translation. 

From time to time, when coding, we all run into weird behaviours of the programming language. Sometimes it's a "feature" we weren't aware of, sometimes it's just quirky behaviour of the language, and sometimes it's borderline bug. Python - as any other programming language - has these eyebrows-raising quirks, so here's a list of weird Python "features" that might catch you off-guard.

At the end of reading this post, you will be able to understand how to estimate a causal effect with retrospective data, get familiar with the concept of confounders, learn how to balance your data using Propensity Score Matching, and most importantly, you will have fully available code to use for your research. If you feel comfortable with Propensity Score Matching, skip to the real-life example and use the code snippets.

A talk covering how to automate document creation using Python-docx and Jinja.

In this blog, we introduce our method for regex-guided generation implemented in Outlines.

Want to learn how to use Python and Playwright to automate end-to-end testing using GitHub Actions? This post shows you how to get started with Playwright, add an end-to-end test to help test an existing project that is hosted on GitHub, and automate running it using GitHub Actions.

Optimizing Django query performance is critical for building performant web applications. Django provides many tools and methods for optimizing database queries in its Database access optimization documentation. In this blog post, we will explore a collection of additional and essential tips I’ve compiled over the years to help you pinpoint and resolve your inefficient Django queries.

Github supports roles instead of credentials of integrating CI/CD with AWS. It’s easy to misconfigure so let’s show the impact.

This writeup introduces what the author calls Bonsai Networks - extremely sparse computational graphs produced by training and pruning RNNs. They provide an interpretable view into the solutions learned by networks for simple logic problems, breaking out of the black box neural networks typically reside in.
