I'm helping my wife build https://quantral.com - initially we put it together to track stock sentiment/crowd wisdom on social networks for our own investments. This is something I was previously doing manually every morning while having breakfast. I couldn't find a similar project to satisfy my needs for discovering hot stocks and the track records of people who mentioned those stocks on finx and /r/wsb. We are now planning to add congressional trading as another data source.

I'm vibe coding a toy chatbot with OpenCode and GLM 5.3 - I'll open source it once it's meaningfully done (keeping the repo private for now until I am _so so_ sure there are no secrets in it!). This has been an exercise in learning about lots of new AI SWE concepts including some tech (Mastra, LangSmith, DeepInfra) - as well as a chance to try some open weights models. The actual useful output is an iteration loop orchestrator based on GitHub issues/PRs which I have found a lot of fun to use. That'll also be open-sourced.

I’m building TraceDB[1] because I think observability needs an overhaul. We pay a premium to index millions of near-identical spans, sample away the rare ones that might explain an outage, and still have to piece together what failed, where it started, and how it spread. All the data is largely there, but no one can make sense of it! Observability was hallucinating before AI made it fashionable.

I’m seeing near-100% root-cause accuracy on synthetic test data and am looking to validate that on real production workloads using OpenTelemetry tracing. If you’re open to chatting or experimenting, drop me a line! I’d also love to hear ideas or how we can improve observability.

This is my attempt to improve my agentic coding workflow by giving the agent an index into the source code through vector embeddings and LLM generated descriptions with local sqlite as the storage backend.

There are many similar tools, but I wanted to learn how such a tool can work by building it myself. What I like about my own version is that I kept things simple - no MCP, no server, no watches, just a CLI that uses git commit hashes to reindex only what has changed.

As we move away from reading code more and more, I started learning about OpenSpec as a way to be more spec oriented to develop software. Reading specs in a code editor didnt make sense so I wrote my “OpenSpec IDE”. Very simple desktop app, no subs or accounts. Its really a markdown reader but built specifically for OpenSpec so you can read things in order and summon Claude (others coming soon) to execute the required OpenSpec commands

https://pro.forth.news

It's an extension of a longer-running project (https://www.forth.news) where it exposes and organizes 100s of newsworthy primary sources -- statements, press releases, press pool reports, emergency alerts, etc, whether from press email lists, X/Twitter, Bluesky, RSS, etc. The web UI is similar to TweetDeck - and it sends notifications.

Latest update now allows some panels to be based on an LLM prompt (i.e. "everything about the Iran War and its effects in the U.S.") which searches the entire catalog of sources as they are posted.

Push notifications for AI agents, but better. It eliminates baby sitting terminals & let's you go out & approve key decisions while you're also notified of the proof of work.

https://notifier.aicrew.in/setup

It renders markdown, screenshots, can send as audio, allows approval & free form reply when it direction.

Convek https://convek.dev/ It's an API (first one) for soaring specific weather data, based on RASP, for paragliders, instrument makers etc. 24 sign ups and ~5 active users, no subscribers yet (one person paid for a month though!). Along with widgets and daily emails for gliding clubs. Trying to get every country but, waiting for some users to add another server (RASP is very compute heavy)

I’ve been working on Pick Up, a reading companion I built to make tracking books feel a bit more personal and fun.

You can track what you’re reading, keep notes and reflections, see your reading stats, build out your bookshelf, and a bunch more. Over 4k monthly active users.

Been building it solo & adding features based on what readers ask for.

https://sumochess.org, a variant of chess where you cannot take pieces but have to push them off the board (and check mate like in real chess).

More intense than normal chess because more pieces stay on the board, and because the push mechanism add to the complexity.
