VERDURE is still a creative plant-generation sandbox where you grow and sculpt stylized trees.
The simplest web framework and site generator yet – no leaky abstractions between you and the high-performance engine that is a modern browser.
I’ve been getting back into movies this year and my 2018 laptop has reached the stage where it’s no longer useful as an everyday tool, so I’m turning it into a home media server.
I’m only a couple days in, and I’ve already learned so much about networks, containers, codecs, ffmpeg, and so on.

Puzzleship - a free daily puzzles website with the archives paywalled. Right now it has Logic Grid Puzzles and Zebra Puzzles. I'm pretty proud of the LGP generator algorithm and some experienced players also liked the way the puzzles are constructed. This is my first subscription site and it's been online for about 15 days, so I'm learning a lot and trying to figure out the pricing.
I started building https://github.com/kcc999/sidechain
It's a CLI Framework for running evaluations against LLMs.

On a mission to build the best interviewer platform with emotional intelligence, to make the conversation comfortable and engaging for the user. Not just a chatbot, but a deep real-time knowledge capture framework with conversational AI.
Our first consumer product is Argo https://getargoai.com, but we're working on a B2B version as well.
We dug deep into what makes a conversation not just a nice chat but a deep, profound, top-notch interview, when the interviewer who neither pries nor forgets.
What makes people come to Joe Rogan or Lex Fridman and talk for 4 hours straight without feeling interrogated or experiencing conversation fatigue?
What if we had an app on our phone that helped us capture a story, filling the gap between two photos?
These are the questions we're excited about. Would love to hear what everyone thinks about conversational AI beyond the typical assistant paradigm.
I'm trying to make 2x15V 150mA DC power supply. The choice paralysis is killing my momentum.
A digital assistant for your Gmail, Google Workspace, Notion and Slack.

Started this out by building a spreadsheet controlled by an LLM. Now putting a direct filesystem inside, simplified enough to have programmatic control of slide builders, spreadsheets, terminals and vibecoding applications
A hobby language called OAF (Oops All Functions). Everything is an argument of a parent function PROGRAM. It's very cursed but it's now fully competent as a general purpose language.
mw-injector[0], it's a WIP project. It detects what Java, Node, Python or Golang services are running on a host and instruments it with Opentelemetry APM. Inspired by Otel-injector[1] but it automatically selects service names for each service so you have service level segregation.

i built a small tool that looks at who is starring a github repo by analyzing public data.
