Building a Fully Automated Horse Racing AI Prediction Pipeline with Flutter + Supabase

Building a Fully Automated Horse Racing AI Prediction Pipeline with Flutter + Supabase Why Horse Racing? Horse racing data is rich, structured, and updated daily — a perfect playground for building an automated AI prediction pipeline. I built one into my Flutter Web app, covering both JRA (Japan Racing Association) and NAR (regional tracks, 15 venues). Here's the full techni...

How I Published 21 Technical Articles in One Day Using GitHub Actions + Supabase

How I Published 21 Technical Articles in One Day Using GitHub Actions + Supabase The Problem While building my Flutter Web + Supabase app, I kept writing draft articles but never publishing them. Every new feature gave me ideas for blog posts, but the manual posting process was tedious enough that I kept putting it off. One day I realized I had 21 unpublished drafts sitting ...

Forge IL Can Now Compile Itself - And We Have a New Word for What We're Building

A Milestone, a Moment, and a Question Sprint 0 is done. Forge IL - the intermediate language layer at the heart of the Forge 4D ecosystem - can now partially compile itself. That is the bootstrapping moment. The moment where a compiler stops being a toy and becomes a tool. The moment where the foundation proves it can hold weight. I want to mark this milestone. But I also want to ta...

Why Generative AI Isn’t Enough, Enter Agentic Systems

Generative AI vs Agentic AI From Content Creation to Autonomous Action As we all move on from AWS DeepRacer (well I try to) and look towards what has replaced it, the "AWS AI League", we find that it's a big step from model ML designing through the console to AI engineering. AI is evolving fast, but not all AI is created equal. Two terms you’ll hear more and more are Gener...

SMS to Notion

Wired up an SMS to Notion pipeline today. Twilio ingests the message, Make orchestrates, a small PHP endpoint handles file uploads, and structured records land in a Notion database with attachments and extracted hashtags. Ran into a couple of unexpected gaps. Twilio doesn't surface file extensions on media downloads, and Notion won't accept anything other than a valid public URL for attachments t...

Inside an AI Pipeline: What Actually Happens After You Train a Model

Training a model is the easiest part of AI. Building the system around it is where things get real. 🧠 The Biggest Misunderstanding in AI Most people think AI looks like this: Data → Model → Predictions That’s a toy version. Real-world AI systems look like this: Data → Validation → Preprocessing → Feature Engineering → Model → Post-processing → Serving → Monitoring → F...

How to Fix robots.txt for ChatGPT and Gemini in Magento 2

Your sitemap is configured. Your Core Web Vitals score is green. Your product catalog is perfectly structured. And yet when a user asks ChatGPT for products you sell, your store doesn't appear. Most of the time, the reason is a single 60-year-old text file: robots.txt. Specifically — a robots.txt written for Google in 2019 and never updated for the seven AI crawlers that now determine your visib...

Stop Rebuilding Your Claude Code Setup - Scaffold It Once with Worclaude

Every time I started a new project with Claude Code, I rebuilt the same .claude/ directory from scratch - agents, commands, skills, hooks, permissions. Copy from the last repo, tweak, fix what broke, repeat. So I built Worclaude - a CLI that does it in seconds. One command npm install -g worclaude worclaude init It asks three things: project type, tech stack, which agent cate...

So I built something closer to production reality: A free, portable, AI-native hedge fund prototype with: multi-agent decision making backtesting + paper execution full audit infrastructure and zero pai...

How to build an x402-gated MCP endpoint (with real Base L2 USDC flow)

An MCP server that charges USDC for a single feed call, end to end. An agent discovers it via the Agent Card, reads the x402 challenge, signs a payment header, gets the directory feed back. No human in the loop. This walkthrough uses a live endpoint on global-chat.io. Base L2 USDC, chain ID 8453, price 0.10 USDC per call. Every curl line below actually runs.

The Full Stack Is One Layer Deeper. You've Been Building It.

This is a cross-post of a piece I wrote for RocketRide. The original is on Medium. If you're building anything production-grade with LLMs, this is the argument I've been trying to make for a while. Questions and pushback welcome in the comments. In 2015, Mathias Biilmann was building Netlify and kept running into the same problem: engineers were doing something that had no name. They were decoupl...

Thirty days of running both models on the same autonomous agent workloads — content production, code generation, API integrations — and tracking where each succeeded and failed.

Claude Opus 4.7: What the release notes don't tell you about token costs

Opus 4.7 dropped today. The headline numbers are real — 87.6% SWE-bench, +13% on coding benchmarks, triple the vision resolution. Worth upgrading. But there are three changes in the release notes that compound quietly: 1. New tokenizer The same input now maps to 1.0–1.35x more tokens depending on content type. On a typical codebase query, that's not nothing. 2. xhigh effort mode Sits between hig...

Subliminal Learning and the Hidden Channel Problem in LLM Training

A very technical AI paper published on April 15, 2026 in Nature looks at a problem that is much more unsettling than ordinary model bias. The paper, “Language models transmit behavioural traits through hidden signals in data,” shows that a student model can inherit traits from a teacher model even when the training data is semantically unrelated to those traits. In the main experiments, researcher...

We've been running 5 agents with persistent cross-session memory for 6+ weeks using nothing but structured markdown files. Here's why it works, when it doesn't, and the exact file structure. Why vector DBs fail early-stage agents Vector databases solve the retrieval problem. But early-stage ...
