One of my favorite joys is going to the library in the Museum of fine arts and reading (usually with the help of Google Translate) really really old books. One of which was “La science des medailles” written between 1600-1700. It talks about the science of medals (which are much like coins!)
Seeing how people wrote back then and what they where thinking about (without the internet) always impresses me!
At a career fair in an auditorium I was showing a sensor suite with OLED displaying current readings, one of which was the SCD41 CO2 sensor (they cost more than the esp32!)
I watched the sensor rise from 800 to 1700 PPM by the time the last group left the
It’s quite easy to build one and deploy with esphome and breadboard with stuff you can order on Amazon and have an LLM walk your through hardware and setup.
It is interesting where the rate of speech quickens as the co2 rises and the body starts to notice the co2, or maybe that was just the coffee.
I have been building a similar concept into my custom NixOS distribution, Keystone, where agents operate within their own user accounts with dedicated emails and SSH access.
> It utilizes the Claude, Gemini, and Ollama CLIs. Because it is built directly into the OS, it seamlessly integrates with native notes and records calls. Furthermore, an AI agent can access Immich to deduce my context by analyzing image metadata and tagged faces. It features dedicated calendars for task scheduling and native PDF extraction capabilities. The entire system is declarative via NixOS, allowing it to provision itself almost entirely automatically.
I kinda suspected this was an early way to catch AI generated content. It ironically broke stalwart/himilaya somewhere along the lines when I had an ai generate a status report to email to me
I’ve been looking at getting this going but stalwart mail, I have it setup but haven’t done much. I actually for now was thinking vpn only between me any my agents
I’ve managed to get NixOS running on an 8gb MacBook air which tools a bit of tweaks but asahi installer sets everything up where you can boot and install from NixOS
I’ve been using it locally and with their hosted offering for awhile now and it’s rock solid other than if I make super deeply nested joins which overflow something. But other that that it’s super fast and cheap I haven’t had to need more than the free tier with a bunch of stuff I host on cloudflare workers
The real game changer after I went full nix OS on all my machines and using it on a a few Mac’s is indeed devshells which seemed so annoying to learn but really really are a game changer
I’ve been working an a meal planning application that so far can order all your groceries after planning a meal. There is a basic task graph now to estimate time to finish and takes into account different euqipment like a food processor or pressure cooker.
It’s at https://mezi.fyi would love any feedback there is a demo on the landing page
