CQRS in Python: Clean Reads, Clean Writes

When your FastAPI list endpoint starts pulling full documents just to compute derived fields, it’s usually a sign your read and write models are drifting apart. This video demonstrates how to refactor a tickets API (FastAPI + MongoDB) using CQRS, explain projections and eventual consistency, and show when this architecture is worth the added complexity, and when it’s not.

Type-based alias analysis in the Toy Optimizer

The post explains the basics of Type Based Alias Analysis (TBAA), a compiler optimization that uses type information to determine whether different memory accesses can alias, enabling more aggressive optimization. It walks through a simple “toy” example to make the concept concrete and shows how TBAA improves generated code by removing unnecessary load and store barriers.

Visual Introduction to PyTorch

This article provides a visual, intuition-first guide to PyTorch, focusing on how tensors and computational graphs enable automatic differentiation. It strips away complex mathematical jargon to explain how the "Autograd" engine tracks operations to compute gradients for neural network training.

Runtime validation in type annotations

The article shows how Python’s typing.Annotated metadata can be used to attach runtime validators to type annotations and then automatically apply those validators when instances are created. It walks through extracting annotation metadata, handling callable validators, and improving error reporting so that annotated fields are validated and meaningful errors are thrown during object ini...

Coodie: A 4-year-old idea brought to life by AI (and some coffee)

After shelving the idea for four years, the author used AI to rapidly bootstrap Coodie, a Pydantic v2 based ODM for Cassandra and ScyllaDB inspired by Beanie for MongoDB. The result is a fully working library with declarative schemas, automatic table management, sync and async APIs, and chainable queries, built largely with AI assistance in a fraction of the time.

The bug fix paradox: why AI agents keep breaking working code

The article explains that when you ask an AI coding agent to fix a bug, it often makes unnecessary changes to working code because it does not explicitly know which behavior should stay the same and which should change, leading to regressions. It then proposes a property-aware code evolution approach that defines a clear bug condition and corresponding preservation properties so the fix ...
