Two and a half hours at Brew Coffee Spot in La Mesa. Everyone below stood up, plugged in, and walked the room through something they made. This is the short version of each one.
01 · Games
He put a dogfight game on the projector, dropped a QR code, and the room joined on their phones and started shooting each other down mid-explanation. His reason for building it: your AI will tell you to use WebSockets, and WebSockets are too slow, and nobody had made the tool yet.
02 · Research
An undergrad walked through her plan to fine-tune Qwen 4B on a single desktop card and measure it against the base model. The room turned into her advisory board for six minutes, arguing for LoRA and for benchmarking against a plain context harness first.
03 · Tools
He saves every output his AI tools produce into a corpus he owns, and asked the obvious question nobody asks: you paid for those tokens, so why are you leaving them locked inside somebody else's product. He went from around a thousand dollars a month in top-tier plans down to two twenty-dollar ones.
04 · Tools
A key product that drops into your environment file so healthcare, finance and legal teams can put AI near data they are not allowed to leak. Asked a hard question about where decryption happens, he said he could not answer it off the top of his head, which is the most useful thing a founder said all night.
05 · Tools
Born from a real compliance deadline at UCSD: contrast, text size and touch targets checked inside the design file, with colorblindness previews you can flip through. It also runs as a server other AI tools can call.
06 · Games
He prototyped his six-engineer hackathon team's whole app in five minutes to get everyone pointed the same way. Then he showed a webcam fruit-catching game he built for his eighty-year-old neighbor's shoulder pain. A kid played it for two hours straight.
07 · Games
Five years of work, with Google Earth loaded into the world so you can fly anywhere. A player sent him a two-page critique about induced versus parasitic drag; he had the AI explain the physics to him plainly and wrote the fix the same day.
08 · Games
Not the processor, the unglamorous stack around it: the cabling, the converters, the error correction, the things that actually stop you going from a hundred qubits to ten thousand. There is a real quantum solver written in Rust running underneath, which is far more simulation than a game needs. He built it while prepping for a job interview, and did not get the job.
09 · Research
A crime-probability model taken step by step from a Jupyter notebook to modular code to a containerized API running live, with separate health checks for the service and for the model. He demoed the live endpoint and then asked the room where to take it next.
10 · Games
Cars, gas, money, flat tires, tickets and river crossings, all the way to Santa Monica. The computer opponents learn by classical reinforcement learning rather than a language model. He balances it by running sixty rounds, handing the log to an AI, and asking what is wrong with his game.
11 · Tools
The work stays on your workstation and the phone only ever gets a picture of it, so nothing lands on the phone and nothing copies out, which is what regulated workplaces need. He built it in three weekends in a language he had never written, after deciding a two-hundred-dollar gadget was not worth buying.
12 · Research
The curves he was generalizing helped him disprove an open conjecture during his research, back when a single render took minutes and he could not actually see the shapes he was working on. Afterwards the AI taught him to vectorize the math, it got a hundred times faster, and now it draws in real time.
13 · Tools
Thirty years of writing software, and he opened with the line that he does not want to write software ever again. Every agent runs in its own sealed container with zero credentials and full hardware access, and closing it leaves nothing behind. His design rule: if you ever notice you are using his app, he has failed.
Every presenter signed a release at the door. Full recordings of individual talks go up only where that presenter has said yes, and names work the same way: a presenter's name appears here once they say yes.
Showing is optional and always has been. Plenty of people come and watch. If you do want to show, there are four ways to do it, and taking the mic is only one of them.
The next date is being scheduled now. If there is something you want in the room next time, or you want a slot, say so in the Discord and it gets taken into account.
