Articles, Tutorials and Talks

Learn RAG From Scratch

Learn how to implement RAG (Retrieval Augmented Generation) from scratch, straight from a LangChain software engineer. This Python course teaches you how to use RAG to combine your own custom data with the power of Large Language Models (LLMs).

Announcing py2wasm: A Python to Wasm compiler
py2wasm converts your Python programs to WebAssembly, running them at 3x faster speeds.

7 Mind-Blowing Kubernetes Hacks
Kubernetes harbors capabilities that even seasoned developers might not be fully aware of. These hacks delve into the more esoteric, yet incredibly potent tricks that can significantly empower those who master them. These are not your everyday tips but profound insights into making Kubernetes do amazing things.

Python Big O: the time complexities of different data structures in Python
This article is primarily meant to act as a Python time complexity cheat sheet for those who already understand what time complexity is and how the time complexity of an operation might affect your code.

Django from first principles
Many people don't realize you can start a Django project with a single file. This series walks through the process of building a simple but non-trivial project by starting with a single file. The project only expands to additional files when it makes sense to move code out of the main file. By the end of the series, we'll have a project with a structure similar to what's generated by startproject and startapp.

Run Llama 3 locally using Ollama and LlamaEdge

Meta has unveiled Llama3, and now you can run it locally using Ollama. In this video, I explain how to use Ollama to operate various language models, specifically focusing on Llama2 and Llama3. I'll also guide you through the WebUI for the project, demonstrating how to serve models with Ollama and interact with them using Python.

Django: Pinpoint upstream changes with Git
In this post, we’ll cover Django’s branching structure, determining and searching through those commits, a worked example, and advanced behavioural searching with git bisect.

Building a Voice Notes App with Django and OpenAI
We'll build a voice notes app that uses OpenAI to perform speech to text. As a bonus, we'll use AlpineJS to manage state on the frontend.

Build a Connect Four game with HTMX and Django in 8 minutes
By the end, you'll have built a multiplayer game using HTMX, using neat server-side logic and storing all results in your database. HTMX is a great way to use javascript without writing javascript.

Trace complex LLM applications with the Langfuse decorator (Python)
When building RAG or agents, lots of LLM calls and non-LLM inputs feeds into the final output. The Langfuse decorator allows you to trace and evaluate holistically.

Learn to use Websockets with Django by building your own ChatGPT
Everything you need to know about websockets to use them in your applications, with Django, channels, and HTMX.

I accidentally built a meme search engine
Or: how to learn about clip/siglip and vector encoding images.

Llama 3: Get building with LLMs in 5 minutes
Get started building transformative AI-powered features within 5 minutes using Llama 3, Ollama, and Python.

Interesting Projects, Tools and Libraries

CoreNet
A library for training deep neural networks by Apple.

Cria
Cria is a library for programmatically running Large Language Models through Python. Cria is built so you need as little configuration as possible — even with more advanced features.

bridge
Automatic infrastructure for Django.

Penzai
A JAX research toolkit for building, editing, and visualizing neural networks.

BeyondLLM
Build, evaluate and observe LLM apps.

Hashquery
A Python framework for defining and querying BI models in your data warehouse.

torchtune
A Native-PyTorch Library for LLM Fine-tuning.

InstructLab
Command-line interface. Use this to chat with the model or train the model (training consumes the taxonomy data)

Portr
Open source ngrok alternative designed for teams

anthropic-cookbook
A collection of notebooks/recipes showcasing some fun and effective ways of using Claude.

New Releases

llama3
This release includes model weights and starting code for pre-trained and instruction tuned Llama 3 language models — including sizes of 8B to 70B parameters.

PyTorch 2.3
PyTorch 2.3 offers support for user-defined Triton kernels in torch.compile, allowing for users to migrate their own Triton kernels from eager without experiencing performance regressions or graph breaks. Tensor Parallelism improves the experience for training Large Language Models using native PyTorch functions, which has been validated on training runs for 100B parameter models. As well, semi-structured sparsity implements semi-structured sparsity as a Tensor subclass, with observed speedups of up to 1.6 over dense matrix multiplication.
