Building Your Own Coding Agent
Build a code-editing agent from scratch in Python ā an LLM, a loop, and three tools in a compact baseline implementation.
Context Engineering
Master the art of managing what goes into a language model's context window ā from tokens and system prompts to tool calls and memory strategies.
Build Your First Chrome Extension
Go from zero knowledge to a working Chrome extension ā learn the fundamentals, security model, and build a real extension that modifies web pages.
Understanding microGPT
Walk through Karpathy's 200-line GPT implementation ā from autograd and tokenization to multi-head attention, training, and text generation.
Understanding Micrograd
Build a neural network from scratch ā Karpathy's autograd engine, neurons, layers, and training ā in pure Python with zero dependencies.
Understanding GPT
Build a GPT language model from scratch in PyTorch ā from a bigram baseline through self-attention, multi-head attention, and full transformer blocks to generating Shakespeare.
Understanding Makemore
Build character-level language models from scratch ā from bigram counting through MLPs, batch normalization, and WaveNet ā generating new names with PyTorch.
Data Structures & Algorithms
Master the fundamental data structures and algorithms that underpin all software ā arrays, linked lists, trees, graphs, sorting, and more ā with typed Python implementations and complexity analysis.
Computer Science Fundamentals
Understand the layers beneath your code ā how CPUs execute programs, how memory hierarchies work, how processes and threads enable concurrency, and how networks connect everything together.
Software Design & Systems
Learn the design patterns, testing practices, and system design principles that separate working code from well-engineered software ā from GoF patterns to scalable distributed architectures.
