I'm building Lexeme (https://trylexeme.com), a SaaS service that tracks how AI models like ChatGPT cite and describe your product vs. competitors, and tells you what to fix first based on estimated revenue exposure.

#112I'm working on Isola (https://github.com/isola-run/isola), a passion project of mine. It allows you to easily create and control sandboxes for executing untrusted code on any Kubernetes cluster (one helm install). To support some features I wanted (like on demand snapshotting of specific containers' filesystem in a sandbox pod or limiting egress rate from the sandbox I am working on now) I contributed some changes to gVisor. Happy to chat about the design and implementation of such a project if anyone interested!

#113Main project is a deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint). Today I upgraded it to net10, which has naturally caused dozens of regressions which Claude is beavering away at.
Side project is my own agent harness, https://github.com/Smaug123/writ , which is being built sandbox-first and with Nix as a first-class citizen. Obviously everyone has to write their own agent harness as a rite of passage.

#114I am working on mesh (https://growmesh.io)
I started working on the topic of human development two years ago and I dived into the topic of how humans have been trained, manipulated, educated or brainwashed.
My central idea which I am investigating is that whenever a person is interacting a highly tuneable ML model such as the X/Fb/TikTok feed or chat interfaces with LLMS, does the thinking and development of the human happens more times or less due to the new experience.

#115I'm continuing to focus on ways to set strong code quality guardrails in an era where most code is not handwritten.
The result is http://getcaliper.dev.
It has a number of mechanisms that help substantially:
1. It can extract deterministic quality checks from your CLAUDE.md text; these checks then get executed after every agent turn.
2. It performs a lightweight ai-powered review at every commit; feedback goes directly to the agent, which can then make corrections.
3. It performs a more 'traditional' deep AI review at merge, or on-demand.
Free to use, just bring your own API key. Any and all feedback is welcome!

#116I’m working on Recoil, memory safe, compiled static language (yeah, I know, everybody’s doing it) with Rebol syntax and built-in candies like parsing, finite state machine and rich syntax (that’s given, because of Rebol).
It’s nice to see how well-thought language design can pay off years later, with lower token usage. From entropy POV, Rebol syntax is certainly close to optimal state.

#119Better GitHub insights: https://temporiohq.com - still new and there’s a lot of question about how to adapt to the age of accelerated software engineering.

#120I'm working on Repple (https://repple.sh)! It's a modern spaced repetition x incremental reading/PDF library app with a few (tasteful!) QOL AI features.
I've been using Anki for 10+ years and love it but always wanted something with a cleaner UX and a reader view. The recent Anki ownership change pushed me to finally make something, and it's seeing some traction :)
Right now I'm focusing on getting the reading and note-taking view to be nice. I used to use Polar Bookshelf (RIP) but that went away, trying to make something better.
The flashcard side also has a REST API btw!
