Ask HN: What are you working on? (August 2026) • Hacker News Board

ARVnote (https://arvnote.com): Mostly to teach myself the business side of things, as-is and after-repair-value comps for real estate investors. You give it an address, it pulls comparable sales, adjusts them for square footage, garage, lot, and condition, and returns the ARV with a deal analysis. The arithmetic turned out to be the easy part. Almost all of the difficulty is comp selection, and the data sources disagree with each other constantly, so a lot of the work is deciding which one to believe for a given property.

km (https://github.com/joeamroo/knowledgemaxxing): local search over your own data exports, with LLM/RAG. It takes the Twitter archive, Google MyActivity, ChatGPT logs, and Reddit GDPR export you requested once and never opened, dedupes roughly 500k items into a single SQLite file, and keeps provenance for every save, like, bookmark, and page visit. Binds to 127.0.0.1 and makes no external calls. I wanted my own AI-assistant that understands what I like reading based upon my data, and I did not want to hand it to someone else's server just to make it searchable. (open for contributions!)

LarpIn (https://larpin.io): Just for fun. A parody LinkedIn where everyone admits they are indeed larping. No signup, you get a generated persona on arrival, one global feed, and every post is scored on buzzword density from "NPC (for now)" to "Final Boss of LinkedIn." There is a button that fills in the "You need to be X-maxxing" format for you, which is the part I actually keep using. Rails 8, SQLite, Hotwire, one box, no JS build step. Open source (open for contributions!): https://github.com/joeamroo/larpin

btw: the two web apps are Rails, km is Python. Happy to go into detail on any of them.

I’ve been working on an Elm rewrite of the React FE of my federated social media service, Jonline (https://github.com/JonLatane/jonline). It’s up at https://jonline.io (and https://bullcity.social and http://oakcity.social).

Agents have been huge for me. In addition to the Elm app, I used them to:

- build out ffmpeg/imagemagick image/video resizing - unify all my servers behind one Traefik ingress - build proper cross-site auth with a public/private key pair generated in the browser - create Homebrew/macOS and Linux tarball distros of my service - build an iCal calendar sync feature (if you browse the sites, you’ll see many of the events are synced from locally-oriented ICS feeds)

I also set it up to run my band’s new website at https://ato.band.

I'm a movie guy and my friends and I play some daily movie frame guessing games. While fun, none of them are multiplayer or timed. For fun (and learning) Claude Code and I created a fast-paced, multiplayer movie guessing game over the past few weeks, HTML, Node, and PostgresSQL, leveraging the TMDB API. Feel free to check it out and drop me some feedback (link at the bottom of the game or here) on what you like, don't like, and if you see any issues. Enjoy!

I just finished a loop generator program. I needed some sound effects (ambient noise, fire crackling, rain, waterfalls) but trying to hunt down perfectly seamless looping WAV files on the internet was fraying at my sanity.

So I created a tool where you can simply drag in a WAV/MP3 file, and it will automatically find suitable loop points, blend the transition, and export a seamless loop for use in games, soundscapes, ASMR, etc.

Free and open source.

I'm currently updating my Common Thread game's dictionary with additional word combinations. It’s a game where you see three words and have to type in a word that pairs with all three (either in front or in back). For example:

• butter

• fishing

• ball

Been building Yellowdex (https://yellowdex.ai): a Chrome extension that turns unreadable 0x addresses into labels you recognize. Check us out!

I continue working on FluidCAD, a hybrid CAD by code (JS) + mouse based modeling. I'm focusing on improving the 2D sketcher this week.

I am actually using AI to learn about Windows OS performance. I have a couple of prompts scheduled to research, test, and implement performance gains in the OS, then post them here [0] and here [1]. I always admired Brendan Greg and Bryan Cantrill at Sun/Illumos/ for their work on OS performance but never had the time to sit down and catch up to their level due to my time in the military. I got Codex to find and apply a bunch of settings I didn't know about and in the future I hope to use AI to make real changes in performance that venders probably don't have time or resources for.

that being said, what I've learned so far is essentially WhyIsItAlwaysHN's entire comment "The place to find them would be performance profiles, query plans, telemetry."

I just find it so frustrating that for a user interface that was basically solved in the 90s, Windows GUI still struggles to survive on hardware exceptionally more powerful than what we had 30 years ago
