Tutorials that start from a broken system
Every walkthrough begins at a real integration failure. You get annotated decision points, copy-pasteable code, and a system that runs at the end — no exercises left to the reader.

FreeRTOS task scheduling on ESP32 under memory pressure
Starts from a watchdog reset that took three sessions to diagnose. Covers heap fragmentation, task priorities, and the exact config that stopped the crashes.
Estimated read: 22 min · Working firmware included
Building a RAG pipeline that survives context overflow
Rooted in a retrieval failure where chunk boundaries destroyed answers. Documents the chunking strategy, embedding model swap, and reranker that fixed recall.

ESP32 · FreeRTOS · MQTT
FastAPI · PyTorch · LangChain
Kafka consumer lag: diagnosis, backpressure, and recovery
Kafka · Docker · Kubernetes
RAG Systems · PydanticAI · Solidity
Begins at a production lag spike that no dashboard explained. Traces partition assignment, consumer group rebalancing, and the config changes that held under load.
Rust · Vector Databases · Grafana
Estimated read: 31 min · Docker Compose environment included
Annotated decisions, not just code
Each step carries inline annotations explaining the tradeoff made — why this queue depth, why this retry strategy, why this model at this precision. The code is reproducible; the reasoning is the tutorial.
Syntax-highlighted blocks are copy-pasteable with zero modification. Where a config depends on your environment, the annotation tells you exactly what to change and why it matters.
