ByteWax: Rust's Research Meets Python's Practicalities

Bytewax is a curious stream processing tool that blends a Python surface with a Rust core to produce something that’s in a similar vein to Kafka Streams or Apache Flink, but with a fundamentally different implementation. This week we’re going to take a look at what it does, how it works in theory, and how the marriage of Python and Rust works in practice.

How Python Asyncio Works: Recreating it from Scratch
Learn how asyncio works by recreating it from scratch with Python generators and using the __await__ under method for the async/await keywords.

A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from an interesting angle.

AsyncIO and the Event Loop Explained

Over the years, I’ve produced several videos about AsyncIO. Today, however, I’m adopting a new approach where I explain the event loop in depth. I’ll delve deeper into asynchronous programming, focusing specifically on how the event loop operates behind the scenes.

How LLMs Work, Explained Without Math
A basic question I think a lot of people have about the GenAI revolution is where does the apparent intelligence these models have come from. In this article, I'm going to attempt to explain in simple terms and without using advanced math how generative text models work, to help you think about them as computer algorithms and not as magic.

Master Python & Zoom API | Build a Server-to-Server App That Transcribes Recordings

Learn how to use Zoom's API with Python in this step-by-step guide! In this tutorial, you'll learn how to create a robust server-to-server OAuth application that automatically transcribes your Zoom recordings, prints them directly to your terminal, and saves them as text files. Perfect for developers, this tutorial will take you from setup to execution, so you'll have a fully functional application by the end of the video.

A High-Level Technical Overview of Fully Homomorphic Encryption
The article provides a high-level technical overview of fully homomorphic encryption (FHE), a powerful cryptographic technique that allows computations to be performed on encrypted data without decrypting it first. It discusses some of the key FHE libraries and tools under active development.

"Attention, Please!": A Visual Guide To The Attention Mechanism
Develop an intuition behind Attention: why it took over machine learning + LLMs and what it actually does.
