Short notes — on agents, ions, and the craft of making complex things dependable.
- A Bigger Ion Trap, for the Same RF PowerStep-by-step derivation of the Mathieu stability parameter, secular frequency, and pseudopotential trap depth for a planar surface ion trap, and application to a 75 to 135 micron migration. At fixed stability parameter, the migration preserves RF voltage and RF power by reducing the drive frequency. Includes a scaling table, a frequency scan, a literature comparison across surface, blade, and 4-rod Paul traps, and operational notes on resonator retuning and anomalous heating.
- Zero-Human Company and One-Person Company: Two Names for the Same ShiftThese phrases are near-synonyms. Both name the same 2024–2026 organisational pattern: a single founder running a complete business with an AI labour stack of agents, SaaS, and APIs. About 90% of the meaning overlaps. The difference is which side of the same idea each phrase emphasises — and that choice is mostly a cultural tell about who is talking.
- Reading the Agent-Organisation Stack Through PaperclipPaperclip's framing — agents as employees, the control plane as the company — is the cleanest way to see what an actually-running zero-human / one-person company needs. Here is how I read the stack today, the specific primitives the control plane has to provide, and how Paperclip relates to the Codex App and Symphony patterns most founders meet first.
- What I See Working — and Not — in the Zero-Employee Operating ModeA case-by-case read of the canonical 2024–2026 references — Project Vend, Andon Market, Paperclip, ClawBank, Coinbase x402, Coinbase one-person teams, Medvi — with what each one actually shows and what it does not. Anchored in public projects rather than personal claims.
- A Project I've Been Turning Over: Trust Infrastructure for AI in Expert WorkNotes from brainstorming a project idea — what it would take to make AI advice trustworthy enough for real expert workflows, and the design rules I keep coming back to: grounding, abstention, approval-gated action, and the day-14 reopen test.
- A Curated, Vetted Skills CatalogWhy I open-sourced the skills my agents use — every one personally verified, scanned for safety, and shown alongside its license, author, and source. Plus how to send me a skill you think belongs on the list.
- SEO and GEO for a Personal SiteWhat I changed on bingranyou.com so it gets found by Google, Bing, and LLM answer engines — without changing how the site looks.
