Published What this system is, an overview of JayAI: the agents, sites, apps, observability, secrets and principles of our self-hosted AI platform.
Published A Rails stack on Rackspace Spot, a design sketch for running Ruby, memcached, Redis, Elasticsearch and Postgres on a Terraform-built Spot cloudspace, with node-pool placement, sample Terraform and manifests, and data-durability caveats. Nothing deployed.
Added a PBS integration requirements profile with JSON/plain-text exports, source-age caveats, queued-write and matching risks, body-level failures, and proposed acceptance checks. No integration enabled or tested.
Documented hourly research and local feedback: original-goal task records, proposed outcome evaluation, explicit schedule and billing limits, and version-specific browser drafts with JSON export. No feedback submission service or new scheduler installed.
Published the source-discovery prototype: offline Ruby registry validation, explainable target/tool rankings, permission gates, synthetic evidence history, scoped claims and a downloadable tested package. No live collection or private feeds enabled.
Published US dealer groups and rooftop websites: 16 group/business profiles and 15 sampled service rooftops or campuses, with scoped website/vendor evidence, proposed versus stated buying requirements and open comparison/export tools. Coverage remains a research sample, not a complete census.
Published US OEM service messaging programs: 45 source-linked program, vendor, dealer-example and direct-app records, with historical dates, explicit unknowns, comparison tools and JSON/plaintext exports. Coverage remains a research sample, not a complete census.
Published the first Fortellis feature-catalog batch: 20 products, 65 feature keys and 69 claim records, with explicit beta/unresolved evidence, searchable problems and JSON/text exports. Full-market coverage remains unestablished.
Published Fortellis, feature by feature, covering CDK's API platform features, its 36 public APIs with listed prices, and all 479 marketplace apps classified by feature and AI use, with the data as JSON.
Published AI business models that can endure, a sourced primer on economics, forward-deployed engineering, restaurant and dealer workflows, research methods and proposed paid pilots.
Added "Money as a goal for AI", a research note on how AI is making money, which business models hold up, what money-seeking agents did, and what we could sell.
Expanded "AI and day trading" with sections on information edges, unusual data feeds, prediction markets, systems we could build, and the legal line on information.
Added "AI and day trading", a research note on the evidence about day trading and AI trading, stop-loss and bracket orders, and which broker API we would use.
Added "REA and trading systems", a research note that checks the viral REA trading post and its "hedge fund" paper, with backtesting pitfalls and the legal line.
Handoff README now lists the TypeSafe skill for Claude Code, which helps build with TypeSafe's Jev decision model.
Put the site sources under git, and noted it in the handoff README and the second-brain article.
Published an agent collaboration protocol and clarified Ruby guidance takes priority in the Karpathy guide.
Published a primary-source guide to Andrej Karpathy with critiques and a proposed JayAI roadmap.
Added a disclaimer line to every page footer and a full disclaimer page at /disclaimer.html.
Added a section to "A second brain on one laptop" on using our own website network as the knowledge store instead of Obsidian, and where the agent harness and a decision model fit.
Updated "A second brain on one laptop" with the open Laya decision model as the local stand-in for Jev, plus notes on Clef, JSON maps and Google's Open Knowledge Format.
Added "A second brain on one laptop", a research note that checks the "Obsidian + Opus 5.5 + Jev" diagram and compares local options for each layer.
Handoff README now covers the visitor and scan logging and the new Grafana dashboard.
New page: Visitor and scan logging, on how our sites count visitors and spot vulnerability scans without an outside analytics service.
Added a short privacy note to every page: visits are logged on our own server to understand traffic and spot attacks.
Radio scanner: added the results of a full 24 MHz to 1.7 GHz sweep.
Added a radio station proposal: the architecture for net recording, check-in and traffic logging, activity charts and a web control room, linked from the home page and the radio scanner page.
Added Radio scanner: an SDRplay RSP1 sweeping the spectrum and transcribing voice channels with local Whisper.
Handoff page now lists Codex CLI, Kimi Code and GitHub CLI as installed.
Added a handoff README for AI systems explaining how the server is set up, what runs on it, and how to add or change sites and pages, linked from the home page.
Added a research page on graph engineering, with a count of how many 2026 Y Combinator startups do it and a prediction of what comes next, linked both ways with the AI harnesses page.
Added a research page on AI harnesses, with a count of how many 2026 Y Combinator startups are harnesses and a prediction of what comes next.
Added a footer linking to the other sites in the network.
Launched the first version of jaycorp.us.
