Just for Fun Tutorials¶

Objective: Master creative and experimental implementations through step-by-step guides. When you need to implement creative solutions, when you want to follow proven patterns, when you need copy-paste runnable examples—these tutorials become your weapon of choice.

Creative & Experimental¶

• Terminal to GIF - Capturing command-line magic and converting to animated GIFs
• Redis Streams + Web MIDI - Procedural MIDI jams with Redis Streams and Web MIDI API
• PostGIS Rasters + WebGL Art - From elevation models to shader dreams with PostGIS and WebGL
• IoT + IPFS + GraphQL + Blender - IoT data in the metaverse with decentralized storage and 3D visualization
• MQTT + TimescaleDB + WebSockets + Three.js - From sensors to sculptures with real-time IoT data as 3D geometry
• Fastify + Kafka + ClickHouse + WASM + WebGPU - Real-time anomaly radar with streaming analytics and GPU visualization
• Gonzo Prometheus Exporter - Building a surreal Prometheus metrics exporter in Docker (weird metrics, real monitoring)
• Git Commit Weather Station - Node.js + RedisTimeSeries + IPFS + WebRTC (in Docker)
• Selenium Grid (Docker) + Python - ChromeDriver headless testing with Docker Compose
• Martin + PostGIS Tiling - Tables, views, SQL functions, and raster tiles with Martin
• Managing People in Software Development - From engineer to leader: essential practices for technical managers
• OSC + MQTT + Prometheus + SuperCollider - Let your metrics sing
• Fractal Art Explorer (JavaScript) - Real-time Mandelbrot/Julia explorer with palettes, orbit traps, and GPU acceleration
• Pi-Based Sample Library Server - Raspberry Pi sample server with SQLite indexing, Nginx, FastAPI, WebAudio, and USB MIDI live audition

Backend Engineering (Go)¶

• Go Auth Backend: Postgres + JWT + bcrypt → scratch + Compose - Minimal Go auth service (register/login/me) with bcrypt password hashing, JWT sessions, Postgres, packaged into a FROM scratch Docker image (~12 MB) orchestrated with Compose. Includes a tiny static healthcheck binary. Go · Docker · Postgres · JWT

Generative Art (Kotlin)¶

• Recursive Cathedral Generator - Grow Gothic cathedral silhouettes from recursive L-system rules using Kotlin + Processing. Deterministic seeds, bilateral symmetry, exportable PNG frames. Kotlin · Processing · L-systems
• MIDI-Driven Particle Nebula - Live MIDI input drives a real-time OpenGL particle simulation. Notes become bursts; velocity becomes brightness; sustain pedal becomes gravity. Kotlin · LWJGL · MIDI
• Cellular Automata Organism Garden - Conway's Game of Life extended with energy accumulation, mutation probability, and heritable lineage coloring. Organisms evolve before your eyes. Kotlin · Processing · Cellular Automata
• Pi-Powered Infinite Art Frame - A headless Kotlin/JVM process on a Raspberry Pi renders generative art continuously, shifts palettes by time of day, and exposes an HTTP API for remote control. Kotlin · Raspberry Pi · Ktor

These tutorials provide the complete machinery for implementing creative and experimental technologies and workflows. Each guide includes production-ready examples, configuration files, and best practices for enterprise deployment.
