https://sewerreport.com I am a dev/sewer inspector, done over 20k inspections for real estate alone. I built the ultimate, AI report generator based on my voice to text notes. Reports, email notifications, stripe integration. Payments and invoices. Unlock reports when paid. Square appointments integrations. Pulls all appointments and fills outs new report fields for me. No copy pasting anything ever again. Very niche…

Nicely done! Those time-saving features are really valuable. I'm working on something similar for home inspectors.

- looks like your output report is an HTML page of text and media. Do you generate any PDFs?

- how much time does a report take to complete?

- how long have you been developing sewerreport.com?

- how many customers do you have?

I'm working on a side-project in my spare time since the end of 2012 (before at the university) with some gaps, which is an append-only DBS with time travel capabilities using a custom storage engine based on COW tries and a (still I think) novel page versioning strategy called Sliding Snapshot. Recently I began work on pooling pages for reuse and a custom allocator for variable page sizes. Before, I had created new instances whenever a page was read from disk instead of reusing instances, so the allocation rate was really high for parallel transactions.

Hey HN, I built Zookish,

https://app.zookish.com/

a “voice orb” that lets your website talk: visitors ask questions in plain English, book demos, search resources all with no forms. We’ve seen a 25% engagement lift on beta sites. I’d love your quick thoughts:

Is voice navigation a gimmick or game-changer?

Which use cases or industries excite you most?

Just started this project last week and don't have anything written up or properly documented yet.

I am trying to see how far I can push AIs to do a research project in physics. I did a PhD in plasma physics a decade ago - I am using the literature survey I did while looking for a problem as my starting point.

The plan is: - Using a few research papers to ground the state of the world, see if I can nudge it towards coming up with a few research problems to tackle. The problem needs to be (1) unsolved and (2) something that is probably solvable in a timeboxed fashion. - Let the AI read more papers to refine the hypothesis, and come up with a plan. - Let another agent write code to run numerical simulations. - And finally do synthesis.

I am curious to see how far it's possible to push the models in this direction. At the very least it hopefully helps new grad students in a copilot capacity.

Nice. You make any coin on this yet?

Exploring the implementation of Dynamicland (dynamicland.org) using Guile Scheme, Hoot (scheme->wasm) and miniKanren. Main write-up can be found here: https://deosjr.github.io/dynamicland/

I cycle between learning about scheme macro hygiene and implementing more and more realtalk/dynamicland demos and trying to grok the programming model. Doing this in the browser is a weird but fun constraint that makes things shareable.

My latest project is a wikipedia explorer: https://deosjr.github.io/dynamicland/wiki.html

I've been digging into WebRTC to understand how it works under the hood. My goal is to eventually build a lightweight media server with SFU capabilities — but focusing on the protocol level, not just using libraries.

To get there, I'm breaking it down into smaller projects. The first one: a basic WebSocket signaling server written in Rust (based on RFC 6455). I'm also learning Rust, so this was a good way to build something real while figuring things out.

On the frontend, I used Angular and just the RTCPeerConnection API — no external WebRTC libs. The focus for now is just signaling: how peers connect, exchange offers/answers, and so on. No media or security handling yet — that's the next step.

Here’s a short demo video on YouTube https://www.youtube.com/watch?v=V_qdW2JchbU It’s not production-ready yet. Right now, each WebSocket connection spins up a new thread, but I plan to rework that using something like Tokio for better performance.

Curious to hear thoughts or suggestions.
