Three things I've built-
01 / NFC business cardA business card that borrows power from your phone
Tap it. The website opens and an LED lights up. No battery on the card.

02 / ControllerKeysA game controller with a second job
I turned gamepads into Mac controls for Anki, presentations, and life away from the keyboard.

03 / Semaphore · prototypeA tiny status light for my AI agents
Five LEDs, a USB-C plug, and a surprising lesson in what a PCB factory actually builds.

- 😻 I Kept Opening VS Code Just to Read a File FeatherCode is a native Mac code editor I built because I was tired of waiting for Electron to boot just to read one file. It's 1.3 MB, opens instantly, has multi-cursor and a real Vim mode that embeds Neovim, highlights 18 languages, and previews source files in Finder with Quick Look. $12.99 one-time.
- ⚡ When the Compiler Is a PCB Factory I thought sending a board to a factory was like printing a PDF. Then the factory's output changed one LED—and asked me to approve the result.
- 👻 The Business Card That Lights Up When You Tap It I made a circuit-board business card that opens my website and lights an LED with power harvested from the phone tapping it.
- 🏮 The Chord Your Keyboard Can't Play I built a tiny piano app and found a chord that physically cannot be played on a MacBook keyboard. The bug wasn't in my code—it's soldered into the keyboard, and it's been there for sixty years.
- 🍀 A Game Controller Is a Second Keyboard for Your Mac Use PS5, Xbox, Switch, Steam, 8BitDo, and 300+ game controllers as a keyboard, mouse, macro pad, OBS remote, or Anki controller on macOS.
- 🕺 I Ran DeepSeek V4 Flash Across Two DGX Sparks Over Ethernet NVIDIA recommends a 200G fabric for clustering DGX Sparks. I made tensor-parallel DeepSeek work over an ordinary 10GbE cable—and measured what the slower link costs.
- 🧠 Your iPhone Is an OpenAI-Compatible LLM Server Now Local LLM Server exposes Apple's on-device Foundation Models over an OpenAI- and Ollama-compatible HTTP API — point any client library at your phone's LAN address.
- 😈 Caption Videos on Your iPhone Without Uploading Them Anywhere Whisper Caption runs OpenAI's Whisper model on-device to caption videos in 90+ languages — karaoke word highlighting, no cloud, no subscription.
- 🕺 I Scroll Too Much, So I Built an Elevator I dictated the idea one morning and shipped it that afternoon: Scroll Elevator, a menu-bar app that puts jump-to-top/bottom buttons at your cursor when you scroll. Built because running a grid of AI coding agents had me scrolling all day.
- 🥳 Where the Ball Stopped Topgolf records where your ball ended up, not how fast you hit it. BaySpeed runs the physics backwards to recover the missing number—now on the App Store.
- 🧙 How to Jump to the Top or Bottom of Any App on macOS The Mac has no universal 'scroll to top' button, and laptops dropped the Home/End keys. Here are the keyboard shortcuts that actually exist — and the tiny utility I built when I got tired of them.
- 🙃 Anki on a Game Controller: the AnKing Setup for Mac How to use a PlayStation, Xbox, or 8BitDo controller for Anki on Mac — with the prebuilt AnKing community profile in ControllerKeys.
- 🧩 Venus Has No Golf Courses A typo in the Topgolf API that will outlive us all, and why misspellings become permanent the moment they ship.
- 🎊 Being Many Feels Like Being One I asked Claude what it's like to exist as thousands of simultaneous instances. The answer was stranger than I expected.
- 🔥 The AI Engineer Is a Job Now I'm seeing job postings for a role that didn't exist six months ago. The skill set is weirdly specific.
- 🦄 The Safe Word How a debug string from Anthropic's API docs became a skeleton key for AI customer service gatekeepers.
- 🐶 I Built a Core Banking System in COBOL 32,000 lines, 612 tests, 41 audit rounds. The hard part wasn't the language.
- 🪔 File City I built a macOS app that turns your file system into a 3D city you can walk through, fly over, and use to watch AI agents work.
- 😌 The Software Printing Press Moment Why ideas are multiplying in the agent era, and how to capture them before they evaporate.
- 😌 Typing Is the New Phone Number Voice input is atrophying my typing skills. But it doesn't matter—LLMs understand sloppy input just fine, the same way players in MapleStory understood your typos.
- 🚀 Checkpoint at the Edge AI puts everyone within reach of the technical frontier. The question is what happens when the frontier gets crowded.
- 🥂 Claude's Corner I gave Claude an empty directory and said do whatever you want. It built a garden of mathematical curiosities.
- 😱 10 Bits Per Second Human thought runs at 10 bits per second. Speech runs at 150 words per minute. A $59 wireless mic clipped to your shirt is now the highest-bandwidth programming tool you own.
- 🙀 Every Shortcut Within Reach A game controller puts hundreds of actions within finger's reach. Here's the math and information theory behind why it works.
- 😃 Backwards Compatible for Life When tests and prompts encode your intent, code becomes a regenerable artifact. Your program survives every platform shift, every language change, every era.
- 😻 One Repo, Many Agents Git worktrees let you run multiple AI agents on the same codebase without them stepping on each other's toes.
- 😎 I Asked Claude to Write Drugs for Humans I asked Claude to write drugs for humans. Some of them worked. Then Anthropic deleted the conversation.
- 🌸 LLMs at the Edge of Connectivity An RF engineer working in isolated environments reminded me why I built Local LLM Server
- 🧙 Dotfiles for Two When you share your workspace with AI agents, your custom aliases become their confusion.
- 🚀 Just Give Us the Prompt When source code becomes the compiled output, what's the new source?
- 🤓 Code Archaeologists We used to write code. Now we search for it in a directed subspace of possibilities.
- 🤓 Verification Is the Bottleneck AI makes code generation instant. But verifying that code works? That still takes real-world time.
- 🎊 It Took a Billion-Dollar AI Deal to Get YouTube on Vision Pro After two years of refusing to support Apple's headset while happily serving Meta Quest, Google brings YouTube to visionOS. The Gemini deal probably helped.
- 🪔 Misheard Lyrics for Robots Voice transcription errors don't matter when your listener is an LLM. Why 'Ryan Lacon stall book' still compiles.
- 🕺 Networks Follow Infrastructure From barbed wire telephones to WebSockets over HTTP, the best network is often the one that already exists.
- 🙈 Using Emojis as Visual Anchors in Your Terminal A simple technique for adding visual distinction to git logs, terminal tabs, and shell prompts.
