State Runtime — Can a Hybrid SSM Be the Application?

I built a web app where the only state is the hidden state of a Mamba/Transformer hybrid. No backend routes, no React useState — just a model, a Postgres, and a WebSocket. What worked, what didn't, and the two things that almost killed it: model intelligence and decode speed.

DeepVector — How Much Retrieval Signal Lives in Mamba's Latent State?

I spent two weeks asking whether Codestral-Mamba-7B's hidden states are good enough for code retrieval without training. Mean-pooling is a disaster, MaxSim recovers a 35× lift, and four different frozen architectures all fail to beat it. The thing that finally worked wasn't more architecture — it was composing the latents with tree-sitter and an LLM.

AI Code Ratio Benchmarks: What Percentage of AI-Generated Code Is Healthy?

0-20% barely used, 20-60% healthy, 60-90% heavy, 90%+ rigorous review. Benchmark ranges for AI-to-manual code ratio — and the drift metric that matters more than the absolute number.

autoportfolio — A Stateful AI Portfolio Manager for Claude Code

I open-sourced an autonomous portfolio manager that runs as a Claude Code plugin. Interactive trading sessions, overnight monitor mode, multi-currency P&L, all driven by a single instruction file. Inspired by Karpathy's autoresearch.

nextjs-indexnow — Ping Bing and Yandex Every Time You Deploy a Next.js Site

I published an open-source Next.js plugin that submits new and changed URLs to IndexNow after every build. Zero sitemap dependency, Turbopack-safe, diff-based. Here's why it exists and how it works.

Launching the Lab — Free AI Templates, Prompts & Agent Blueprints

I rebuilt my personal website from a static portfolio into a creator hub. Today I'm opening the Lab — a free resource library with AI agent templates, trading prompts, and starter kits.

Friction Detection: How to Identify When AI Coding Assistants Waste Developer Time

AI tools fail silently. Your DevEx dashboard can't tell a productive session from a prompt loop. Friction detection is the missing metric.

How to Detect AI-Generated vs. Human-Written Code at the Commit Level

Legacy SEI tools guess whether code is AI-generated from IDE telemetry. First-party attribution gives you deterministic, per-file ground truth without monitoring developers.

Beyond the Prompt: Why Your AI Teammate Needs a Memory

Most AI coding tools operate in a vacuum. Tandemu introduces persistent memory that learns your style, adapts to your personality, and gives leads real metrics.
