I am working on https://baolib.org.

Applications on the public cloud raise strong concerns about data protection. As an architect, I spend a meaningful part of my time ensuring the security of customers’ data in the cloud.

Bao introduces an innovative approach where data remains on local devices while the cloud provides encrypted storage for synchronization and peer exchange. Because cloud providers cannot access the data, the need for due diligence is reduced.

Any feedback is welcome.

Any connection with bao or openbao, the fork of hashicorp vault ? I fail to see any reference on the site

Stained Glass Atlas (https://stainedglassatlas.com/) - working on mapping/documenting as much of the publicly accessible stained glass as possible. No fancy tech (vanilla HTML/CSS/JS). Anyone who knows of great stained glass in their local area is welcome to come add to the data set!

I'm building a proxy that sits between Claude Code and the model to visualize the full interaction loop. It shows prompts, tool calls, and responses in real time so you can explore how the coding agent is reasoning and operating. Project: https://github.com/tndata/CodingAgentExplorer

Building grith — OS-level syscall interception for AI coding agents.

The problem: every agent (Cline, Aider, Codex, Claude Code) has unrestricted access to your filesystem, shell, and network. When they process untrusted content — a cloned repo, a dependency README — they’re prompt injection vectors with full machine access. No existing tool evaluates what the agent actually does at the syscall level.

grith wraps any CLI agent without modification. OS-level interception captures every file open, network call, and process spawn, then runs it through 17 independent security filters in parallel across three phases (~15ms total). Composite score routes each call: auto-allow, auto-deny, or queue for async review. Most will auto approve - which eliminates approval fatigue.

Also does per-session cost tracking and audit trails as a side effect of intercepting everything.

Each syscall taking 15ms on top of the normal considered costly time taken for context switching to the kernel seems excessivly slow, no?

It’s fast in terms of a response from a LLM model - but it is part of the system I am quite active on at the moment to ensure it’s performant as possible

I'm most excited about reducing friction for digital payments of APIs and resources in the agentic commerce world.

I think the first step is standardizing HTTP 402 using traditional, familiar payment rails like Stripe, then we can move to things like on-chain or other rails later.

I am building https://stripe402.com to try to make it dead simple for those building APIs/resources to get paid per request through stripe without user's needing to sign up for accounts, get API keys, any of that normal painful workflow required today.

Check it out and feedback welcome!

Still working on https://kavla.dev

I have worked with data for a while. I feel like our tools could be much better when it comes to "flow". I want an experience where you don't need to alt+tab to slack/images/another query. What if we put it all on a canvas? That's what Kavla is all about!

Since last month I've done a lot of improvements to the editor to make the "flow" better.

I've also read up on HMAC, Nonces and fun encryption stuff to create read only boards.

Here's one where I look at stack overflow survey for databases: https://app.kavla.dev/v/mqhg54o319doya4.67dbfee1ccd6caf638d3...

Snowflake users apparently make the most money!

I'm building a microreading service that let's me get long books read with small chunks of time that I have - https://lauselt.ee Currently I've added some public domain Estonian books in there and tbh I do get a lot more reading done during the day. Basically you can use your 1-5 min breaks (waiting for a bus, during the commercials, waiting for food etc) to open the book quickly where you left off and read by scrolling small chunks of texts at a time. Duolingo style streak to create the habit of reading every day. Also the ability to upload your own book and it will automatically be split into these small chunks.

Adding new openly licensed learning resources to the Kolibri offline learning platform. It is designed to be deployed in communities that lack consistent access to the public internet. They currently have a significant amount of English language content, but are limited in what they have available in the dozens of other languages they have translated the core software into. I'm trying to bring in new resources and then try to lead an effort to do translations of the best materials I can find to make the platform more useful to more people.

Also trying to recruit people to teach tech newbies how to build their own handheld video game consoles. Let me know if you might like to run a class where you live and i'll share my class materials.

I'm building AthenaOS: https://athena-os.ai/

Basically OpenClaw but with investing dashboards for my portfolio, additional tools specifically for investing, and exploring an AI-Human collaboration on researching economics (check the 'community' tab).

The data models are all in markdown and Excel so that there's no lockin and you can manually edit positions, personalities, etc.

This comes from frustration around most investing tools basically scraping your personal data + forcing you to lock into subscriptions. I think it's now possible to just vibe code most of what one needs, aside form raw data subscriptions.

It's all open source, too: https://github.com/wgryc/athena-os

I am building ReifyDB(reifydb.com), a database for live application state.

A lot of existing databases are storage first, with everything else built around them. I have been exploring what it looks like if the database is closer to the application runtime itself, where state is live, queryable, and easier to reason about directly.

One thing I am prototyping right now is database-native tests.

Basically: what if integration tests were a database primitive?

CREATE TEST test::insert { INSERT test::users [{ id: 99, name: "Ghost" }]; FROM test::users | FILTER id == 99 | ASSERT { name == "Ghost" }; };

So not a wrapper, not a framework, not an external test runner.

A real test object inside the database.

The idea is that you could run these before schema changes, and make stored procedures or other database logic much easier to test without leaving the database model.

Still early, but it feels like one of those things that should just exist, especially for databases built around live application state.
