Why Logic Belongs in Prompts, Not Code: What I Learned Creating A Broken Agentic System
A hands-on case study of redesigning an LLM-driven school announcement system, contrasting brittle procedural pipelines with agentic architectures. I detail the failure modes, prompt engineering, tool loops, stress tests, and a reproducible agentic blueprint—explaining tradeoffs, debugging patterns, and advice for building robust, maintainable LLM-powered systems that can reason and take actions…
Jansen’s Linkage Optimization
A rigorous comparative study of Gradient Descent, Genetic Algorithms and Simulated Annealing applied to Jansen’s 13-link mechanism. Describes experimental setup, RMSE objective, grid-search hyperparameter tuning, statistical analysis and convergence behavior—showing SA’s robustness on this multimodal inverse-kinematics problem and providing concrete guidance for mechanism optimization.
From Digital Bops to Twigs Snapping in Swedish Woods
An experiment in 'naturalizing' UI sounds by adding stochastic pitch, timing, spectral and envelope variation. I analyze recorded natural clicks, show a Python/Tkinter prototype that randomizes volume, pitch, jitter and spectral tilt, and argue how subtle organic variation can make digital interfaces feel warmer and less fatiguing.

Neutron v2: October Feature Snapshot
Where I'm up to and what Neutron is currently offering in it's latest build.
Hot Hands in the NBA: Is the Streak Real?
An empirical investigation of the NBA hot-hand phenomenon using 2024 shot-by-shot data. I compute conditional probabilities of makes after makes vs makes after misses, visualize player-level differences and aggregate effects, and interpret results against classic literature to determine whether streaks reflect genuine performance shifts or cognitive pattern-seeking. Includes charts, methodology,…
Neutron v2 Devblog: New Features, New Visuals
A development update on Neutron v2 covering rendering pipeline improvements (batching, z-sorting, shaders), swept AABB collision, audio and input upgrades, and the modular GameObject pattern. Includes screenshots, code snippets and a roadmap for deeper AI integration to let models author and modify game elements at runtime.
Ship Fast Directory: Tools to 10x Your Product Launch Speed
A curated, opinionated directory of high-leverage developer and SaaS tools to help indie hackers and small teams launch products quickly. Organised by category (deploy, auth, headless CMS, UI kits, payments), each entry includes why it speeds product development and how to integrate it with minimal plumbing. Useful for fast prototyping and shipping MVPs.
