alt Hacker NewsAsk HN: What are you working on? (August 2026)
What are you working on? What have you been curious about lately?
Comments
I'm working on writing up pages for projecthammer.org, the new website where I'll host my database of Canadian grocery prices. It's getting interest from more academics and needs a more formal home.
I've been curious about ways in which politicians who are in the minority/out of power can still make progress on issues that matter to them.
Lots of fun projects being listed. I'm working on Preloop(https://preloop.dev), a way to run your unmodified Github Actions locally or self-hosted in isolated cross-platform microvms(uses smolvm which uses libkrun vmm).I got frustrated with Github Actions reliability and inability to run or test my workflows locally so i re-wrote the runner and reverse-engineered the control plane so it follows the exact runner protocol the offficial runner does. Each job runs in a microvm that boots in 400ms from a packed image. Also supports a way to pause on every failure so you or your agent can immediately shell at that point, fix and retry(in a new environment) to verify. Also supports the full DAP protocol so you can interactively step/forward/investigate context at each step/job.
Try it out: https://github.com/preloopdev/preloop
I’m working on a native UI framework in rust. I want to be able to build cross platform, fully native applications with native code. And I want platform native components.
I started with Leptos - which gives you a nice declarative UI syntax and reactive elements. I used Claude to get that working on iOS, cocoa and GTK. I made a nice little iOS schedule app for attendees at conferences. It works great. All rust, native UI and a fast and small binary. The current UI code is here: https://github.com/josephg/leptos-native (not officially part of leptos). It works well, but not all of the components I want have been implemented.
At the moment I’m rewriting the core to ditch the vibe coded parts and break the whole thing into an app backend API and separate platform layer. I want to be able to write apps in wasm and have a windows / mac / Linux host that can run them using native UI. And a runner to run any app using a TUI. And have a compilation process to compile the whole thing into a single native process for app developers and to publish to the App Store.
I have been working on and off on https://www.whichtemple.in
- it is a collection of ~ 2700 temples across India, with images sourced from wikipedia
- it shows you a random temple each time you visit
- it has a map view of temples across India
So this is just the tip of the iceberg. I am trying to build a catalogue of all temples, starting with India, and expanding on to the rest of the world. The focus is on temples originating from Indic religions like Hinduism, Jainism and Buddhism.
I have personally discovered many cool temples that I have never heard of, but I am struggling on how to gamify this. Feedback welcome!

My two biggest projects are:
https://www.idlequest.net/ - a from-scratch recreation of the 1999 MMORPG classic EverQuest, featuring a real-time MMO server written in Go, a 3D game browser-based client built with Babylon.js, and the clasic UI recreated using React. You can play it both as a regular MMORPG but also in "idle mode" where it basically plays itself. This had up to 70 players online at once a while back which was really cool, though its popularity is in a bit of a lull right now. There are still tons of bugs and stuff that isn't fully implemented (and balance issues) but it's still fun for most people who have nostalgia for it.
https://www.newyokosuka.com/ - an unofficial Shenmue MMO experience. Based on the 1999 Sega Dreamcast game Shenmue, it's playable entirely in your browser! It's basic world exploration with forklift shenanigans, some basic dialogue systems, and a basic combat system test, but I'm about to push an update that includes all cutscenes and story progression as well. The story part is taking a bit of time because I'm having to mold it to fit in an MMO context. But it's a fun project to work on and the Shenmue community loves it so far.
Browser automation + LLM agents + human curation.
The naive approach has the LLM interacting with the DOM using raw locators and javascript. If a human curates all logical views of the DOM and exposes tools that are only relevant for each, the search space for each agent iteration is reduced by many dimensions. I have achieved deterministic results over hundreds of actions in complex business workflows. Without the human curated layer we barely make it 10-20 actions before things get weird.
Most of my thoughts are currently occupied with possibility that this works in the general case. I think an LLM exercising a tool like GitHub via properly curated browser automation might be superior to direct API access in some ways.
These are all really good comments and ideas! I created a tool to help facilitate, track and recover lost revenue from Stripe subscriptions for SaaS companies. Called RertyForge, www.retryforge.com It lets a failed payment be seen from a company owner’s perspective. Why things fail, what works best to recover it, what step of the process is most successful, who is most at risk right now. It’s bootstrapped and just getting it off the ground. Love any feedback or questions
I'm (solo) spinning off the internal agent knowledge and observability layer used at Motion (YC W20, series C, ~40 devs). It was born out of a need to lift all devs using heterogeneous models, harnesses, and prompting styles to a higher level of consistency and quality while surfacing the visibility to see what's working and what's not. The knowledge layer is integrated into the code review layer and all of it tied together with telemetry to the document section level to see how each piece of context is affecting code generation.

I'm building an AI agent that plays Slay the Spire. It currently reaches A20 Act 3 consistently and occasionally defeats the A20 Heart. It use two search: spare graph search for deck building, and MCTS for combat.
Parallelly, I'm working on an attention-based memory retrieval system that achieved SOTA on LongMemEval, LoCoMo, and code retrieval benchmarks. https://github.com/AttemorySystem/attemory/
Maybe later I'll build a live-streaming AI agent that plays Slay the Spire while conversing with viewers and remembering everything in chat!
I've been building the most advanced automotive diagnostic app on the market
I used to be a mechanic, and spend a lot of my free time working on project vehicles, motorcycles, tractors, trucks etc. I wanted a tool to track the tasks I needed done, then a way to easily access VIN info for parts search, then I DMV records, and finally built an iphone app to scan the OBD2 diagnostic codes and hook them up to a custom ai diagnostic prompt.
It's been a blast to work on, I need to focus on marketing it and get some users that aren't close friends, but it's been serving my purposes this summer so far.
I've seen nothing with anywhere close to this depth of diagnostic reporting.

A boat game for 5+ age group!
I was never much of a game developer, but recently my 5 year old son wanted to play a game so we decided to build one together.
It's a boat game, you basically steer a boat in an isometric 2d world, transporting passengers, cargo etc between ports.
As we designed it, the ideas just kept on coming. He made or directed a lot of the art inside of the game (even the audio), and we included friends and family as characters within the game.
A lot of fun to build - hilarious at times. I used Lua and LÖVE2D, building basically a game engine for an isometric world, so that took significantly more time than expected.
If you want to test it [1], please do, but keep in mind it's only in Norwegian, but I am sure most people would be able to figure it out as it's meant for age group 5 and up:
[1] https://apps.apple.com/no/app/b%C3%A5tspillet/id6791630382
At this point our entire extended family and their kids, grandchildren etc are actually playing this, so it's been super fun.
Vibe, my Winamp-like MacOS music player.
I use it every day, but had stopped dev on it a few years ago. Fable has gotten me excited to take it off the shelf and add a bunch of features I've been wanting for a while. Working on localization now.

I'm going whole-hog on LLM-driven development to build out an old-school FOSS forum that can run in resource-constrained environments with a minimum of fuss. Think phpBB but written in Rust with modern UI niceties and a SQLite backend. My hope is that interested parties will be able to deploy this on random SBCs or Unikraft and use cloudflared to expose their service to interested parties. Watching old forums that I used to frequent get gobbled up by VerticalScope makes me pine for the days of small self-hosted communities that existed for the hell of it instead of monetized interaction.
The last time somebody made this thread, I posted about https://the-waterline.com/, a site I launched as a side project/eval to see how well Claude can do a decent-sized project (mostly) independently. It pulls public government data about water levels in the western US, updates the website and sends out a newsletter.
It started getting some search impressions and clicks, so I decided to launch the next 9 of the top 10 ideas that ChatGPT came up with for this type of site - won't post all of them here, but https://the-dwell.com/ (data on ship and truck dwell times/port congestion) is doing the best thus far from a traffic perspective.
First I had it send me a weekly analysis of the GA4/GSC data to see what could be improved about the site, but I've since automated that - each week it reviews traffic and search queries, then updates articles or creates new ones to meet demand. So now in theory I have a full engine to launch these sites and have them self-improve over time. Kinda neat to see all of that being done autonomously.
The thing that these sites really need are some backlinks, so I'm thinking through how to get those. I had ChatGPT generate some lists of places that might find real value in linking to these sorts of things, but I'm unwilling to let an AI agent start emailing people. I'm going to try sending some emails to some of the places that seem like a really good fit, see what the response is, and if it's good try to figure out how to do that on a larger scale without AI email spam.
The final stretch of getting my game ready for release next week: https://store.steampowered.com/app/2764460/Sandustry/
It's an automation game and factory builder with "falling sand" physics. Think Noita meets Factorio.
I'm working on Dictatorship Simulator. A deckbuilder where, instead of directly attacking your enemy, you manipulate a political simulation to do it for you. You start out on the fringe, and slowly work your way up, fighting an increasingly worried and panicky government - as well as your own.

Im working on what i call a spreadsheet data platform. It looks like a spreadsheet but all the components are plugins which means the user can provide (even write their own).
- Dont like the limited functions available in formulas, write your own. Yes i know this isnt new, just highlighting a starting example.
- Dont like how values are formatted in calls, write your own.
- Dont like templates, write your own script that generates the "empty" or not so empty spreadsheet.
- Dont like clicking on icons, write your own scripts or plugins that execute in context, which makes snippets to do basic things become very brief, because theres no need to load and save the file with the spreadsheet or even select the range with a query.
- Want a terminal, i have one. Everything in a spreadsheet is a file, just like *nix. Read/write a cell, is as simple as reading /cell/A1.txt or /spreadsheet/123/cell/A1, because the environment has smarts like environment values (eg SPREADSHEET_ID) that are used.
I have many other ideas which are nearly there.
I finished wiring up the backend data merge so user(s) (aka me, really) can record trees as they walk and have those merged into the general city data on my urban tree map app[1]. There's some very cool trees in the neighborhood I'm excited to have recorded.
Which leads me to trying to get the processing off github actions (it's all duckdb pipelines), which has led me to improve the orchestration implementation of my 'better sql' [2] to optimize the asset based refresh flow. I'm now wiring that up in a general cloud service to give me the data orchestration platform I've always wanted. Building a multi-tenant cloud experience has been interesting!

A tmux plugin that makes is better to work with many agents:
https://github.com/Ymirke/tmux-agent-switcher
You press ctrl+n and you get a sidebar showing all the tmux tabs you currently have and the statuses of the agents.
The sidebar then has a couple different navigation modes based on what floats your boat, toggle by tab:
1. Using vim bindings j/k, and supporting number -> j/k to go up or down quickly.
2. Using number -> number. Meaning you press the number of session then number of tab.
3. Using search, useful if you have a ton of sessions open.
I really like what herdr, cmux and others are doing in this space, but I find it hard to get myself away from my core tmux setup, so I made this to not have to change too much of how I work.
I'm building an uptime monitoring service, in Elixir, called https://larm.dev. It's a tough field because for some reason people vibe coding apps think this is very easy to do, and there are new apps coming out pretty much every day. I'm still figuring out how to effectively stand out in the noise.
I really enjoy working on the app though. The backend is Elixir, with a Phoenix LiveView dashboard. I've got a cluster of 3 nodes running, talking to each other. The probes that check the monitoring targets are tiny go binaries, spread across hosting providers across the world. I've also got synthetic probes now, running in little playwright sandboxes.
A lot of the challenges have been around how to distribute work across the probes, with different strategies for the basic TCP/HTTP probes vs the synthetic workers, and how to effectively store large amounts of events (Clickhouse).
Launched a suite of media inspection and encoding tools a few months ago, based on FFmpeg. Slowly getting more customers.
Constantly iterating through refinement and features. It's built on Rust + Tauri with a React frontend, in case anyone is curious.
I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium with an IDE-like experience.
Most recently I added a /playground area to experiment with the inspection tools via a WASM build, which I thought was a neat way for users to try the app before downloading the full version.
Happy to answer any questions!
A Drobpox like app that works with FTP and every other storage protocol along gateways to access your Dropbox over FTP, SFTP, S3:
- the desktop client: https://github.com/mickael-kerjean/fdrive
- the web client: https://github.com/mickael-kerjean/filestash
https://dipstickalerts.com - I've been working on this during my kid's naps.
The web app allows car owners in the U.S. to see a list of all the service bulletins the manufacturer has sent out about your car over the years (called Technical Service Bulletins or TSBs). You can subscribe for new bulletins to be sent to your email as well.
These service bulletins are not only recalls but also fixes for known issues with the car.
I found reading these bulletins super helpful for my own car. There were some symptoms I would have never noticed without reading through these bulletins. For example: the tailgate did not lift up all the way in cold weather. Turns out this was fixed and covered under the extended warranty.
The infrastructure is all built on top of Cloudflare workers. I use Gemini Flash Lite to summarize and filter the bulletins.
This is my first web app (thank you AI) so any feedback is welcome!
I created a make-your-own-circuit simulator in python to help learn electronics. The best part about this is that it is entirely hosted online and people can just go through the lessons, learn electronics by skipping the maths, and in the process have made their own circuit simulator (which is arguably a pretty cool project on its own) at the end of it.
I've been working on a Persian classical poetry archive with LLM-generated translation. As a poetry enthusiast but a non-speaker of Persian, I wanted to read Rumi, Hafiz, and Bedil, but found myself jumping between ChatGPT and Google Translate. I sourced my data from Ganjoor, which was luckily available via their public API. Then I quickly put together a website with bring-your-own-key translation feature.
For now, there's no backend and it's hosted on GitHub Pages; it's a static website reading chunks from an sqlite-based DB file. I intend to change it in the future by running an LLM (preferably a frontier Gemini model, as works great for Persian) over the whole data set so you won't need a key to read the translated poetry. However, I don't have the budget of $1000-$2000 to spend on the tokens currently.

I got sick of being on Zoom calls and having things lag or glitch, and not knowing if the issue was something I'm responsible for or not. Is it my LAN/Wi-Fi, my ISP path, some broader Internet issue, or Zoom?
So, I built a tool to answer that. Major goals have been to keep low energy/cpu usage (so I can run it 24/7), have it adapt to the apps/traffic I'm using (rather than use static monitoring endpoints), and to deliver both at-a-glance answers in the menubar and in-depth detail in the dropdown.
It's called Breakdown. It's a free (for typical uses). It's Mac-only for now (but if enough people ask for Windows I'll port it).
Working on open sourcing my data analytics canvas: https://kavla.dev/
I've worked on it for about a year, with 1700 commits. I've been going back and forth if I should just open up the canvas or also the multiplayer experience.
I've always had the dream to make some money from a side project, but I don't think this one is it, so I'll just make the entire repo public. Just want to clean up some stuff first.
Lots of fun tech used: duckDB WASM, Cloudflare Durable Objects, tldraw and pocketbase
An agent harness that is kind of like airflow for agent tasks.
I thought open claw was cool but could never use something so insecure.
Each run is in a container. One network bridge out so everything from tool calls to model communication goes over the bridge.
Each run has a capability token and the host checks grants for the tools attempting to be called.
Core super thin and everything from credentials handling to model communication is a package.
Finally got it alpha and have some useful jobs set up like it triggering jobs on an alert channel in slack. Debugging it with tools like GitHub kube and our work mcp and the dropping a comment on every alert with the cause.
Still closed source but hoping to change that after some more testing.
I’m exploring how to use AI for faith oriented experiences and products. There are two specific areas I’m interested in. I’m furthest along with this app in the App Store. https://trysojourn.app
1) grounding LLM scripture references in the actual text and eliminating hallucinations. This is the platform for that. https://withlattice.com
2) how to use AI to get people into scripture more as opposed to being a substitute for it. This is the product I made for it - it uses #1 above. https://trysojourn.app
Typegres - SQL over RPC safely (safely compose queries over Cap'n Web):
At a high level: 1. Define your schema: TS classes model each one of your underlying tables. 2. Encapsulate your schema: Add methods on those classes (encapsulation 101 applied to your database) -- that compile down to SQL. This gives you the equivalent of computed columns and first-class relations 3. Expose your API: explicitly mark members of your classes to expose 4. Use it: Now - and this is the crazy part - the client (e.g., a web browser) can use your data-model directly to query data with SQL-level power (joins, aggregations, etc -- compiling into a single query) over RPC, securely!
Real example visuals are better at describing it: https://typegres.com/
Recently added SQLite support and live queries; playground shows the live queries: https://typegres.com/play/
Working on the chainsaw for my centaur form factor robot. Have one part to machine then just need to weld everything up and will be ready to try it out. It uses a motor and controller sourced from an E foil, and has 2DOF position control. https://www.satyress.com/buildprogress
I've also been slowly chipping away at a Jagged Alliance 2-like game in Godot. Nothing to share yet but if anyone else is also frustrated that there hasn't been a good video game since Jagged Alliance 2 and you want to work on it reach out to me through the contact in my profile.
I'm figuring out stepping stones in getting closer to user data autonomy. A natural starting place is our professional history.
So, I'm building a compatibility layer; something that works with everything - including your own vibe-coded personal CRM.
It's already helping - even something as simple as correlating calendar events with new connections so that you always know where you met someone.
https://tend2thrive.com if you're curious; It's live, so DM me if you'd like an account rather than just hitting the waitlist.
I put my flat in the UK on the market recently and it has given me a lot of insights into how broken the real estate market is! One thing I found particularly annoying is how dominant rightmove is and how much of the traffic for house hunting they control.
As a small way of standing up to them I created https://rigove.co.uk/ (rightmove without htm - the hidden toll machine ;)
If you change rightmove to rigove while browsing a property for sale you get a page which shows where else that property is listed.
It is only a few days old so it is currently more miss than hit but I plan to reach out to estate agents to increase coverage as quick as I can.
I'm working on https://wireplug.org:
wireplug lets you create mesh VPNs using standard WireGuard. Your wg config files stay almost the same, except you no longer have to specify an `Endpoint` for your peers. Instead, wireplug detects all your possible endpoints (including LAN) and coordinates them with your peers for you. It handles NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD. This lets you keep managing your own keys and network topology, while also maintaining connectivity when moving between networks.
Currently working on improving NAT traversal by adding support for PCP and NAT-PMP.
I've been building https://consciousnesslibrary.org, an open library for psychedelic and consciousness research that pulls from over a dozen academic APIs every 20 minutes, dedupes them, organizes by relevance, and synthesizes evidence.
I just finished my master's in Psychedelics and Consciousness Studies, and built the library I wanted while studying. I started it over a year ago, but put it down until my practicum advisor suggested I dust it off and go hard on it during my last term.
As of this writing, there are over 35,700 papers by over 82,200 authors organized into 37 topics, growing daily. There's a 2D map of the whole corpus and evidence syntheses on the topic pages, plus the ability to generate your own syntheses with any prompt.
It's built with Rails 8.1, uses one Postgres (for full-text search, vectors, and job queue), and runs on a $24/mo DigitalOcean droplet that I just upgraded from the $12 tier and deploy to with Kamal. Total LLM spend so far is ~$28 in DeepSeek-V4-Flash, trending down after a big one-time backfill push.
Relevance was the hardest part to get right by far. Ensuring we keep papers on LSD the psychedelic vs Lumpy Skin Disease, or Ketamine for depression vs anesthesia in cats was no small feat. The design ended up being a cheap keyword prefilter, then an LLM rubric that accepts or rejects papers. More on that here: https://consciousnesslibrary.org/docs/article-pipeline.html
It's free, no ads, no signup to read anything, and a registered 501(c)(3) I fund myself for now. I'd really like to know what breaks or any other feedback, and would love to answer any questions about it!
I'm still working on https://openaltfinder.com; a directory to help people discover open-source projects. Added quite a bit of new features over the last month, including a new weekly newsletter, and a way for people to find beginner friendly issues: https://openaltfinder.com/contribute
It's been tough, for some reason both Google and Bing completely erased my site from their indexes.
Another thing I'm working on: https://getpinnd.com - A small social network for map makers.
Working on https://radius.to/ - a Meetup.com alternative of sorts - with fairer organiser pricing for smaller groups.
I posted a Show HN [1] here a while back, got tons of great feedback, and have been slowly improving it since, with no real marketing. Another Show HN is probably (definitely) overdue!
Current focus is shipping a "Meet people doing X" feature - i.e. "I'm going for a cycle today in Richmond Park - who wants to join" (independent from groups) so I'm excited for that. There are some UI examples of how that will look on the landing page.
I got laid off recently and finally decided to dedicate some time to learn Rust, I started to work on an an idea I've head for a while, to create a game server to play Thai chess inspired by lichess.org, in fact, I plan to use several of their assets.
I'll use Rust for the backend even though it's probably an over kill, but it's the best way to learn for me, doing something with the language. I have some of the front end move logic and board done, I plan to start working on the API soon, after I finish a Rust book I'm reading. Here's some of the code if anybody is interested: https://github.com/thaichess-org.
I’m working on ProofLeague, an app for keeping workout promises with friends:
https://proofleague.com (iOS, web app and android)
You create a private league, set a weekly goal (workout 3x a week), and tap Start when you begin a workout. Friends get notified and then have 30 minutes to ask for a selfie. If nobody asks, the workout counts automatically. There’s no public feed or strangers involved, just a small group keeping each other honest.
My friends and I had been doing a version of this via text message for years, but this app has been great. I am in 4 "leagues", all of them get notified at once and then I only share my selfie once and it automatically goes to any group that asks. It's motivating and hilarious to see people working out.
It's free and would love for you guys to try it and set up a league with friends or family. Please send me any feedback at [email protected]
Mu - Tools for Agents. An MCP server and web app that provides real time access to news, markets, weather, video, places, search, etc. It's sort of extension of a previous idea I had to put all the key tools and services behind a single api and access token. I don't know that it's quite there yet. The idea might change. Still looking for feedback.
https://micro.mu https://github.com/micro/mu
Also have an agent harness and service framework in Go
I’m currently on the beach at Google (since mid July), so I’m looking internally and externally for a new role. But I’m exhausted, so I’m playing around with local LLMs and DeepSeek more as well. I’m currently trying to get an agent harness going where orchestration happens via bazel, and agents are completely isolated beyond what context you give them access to as expressed in starlark. Agent executions are organized as a DAG like a build would be, where the output of one agent can serve as context for another (there is also a feedback mechanism which is needed for arbiter nodes).
I’ve mentioned it before, but we can get some pretty good results for developing implementation and tests with this setup. The context isolation makes it easy to separate test and code writing using a specification as a source of truth. Tests are then run by an arbiter that feedback to tests or implementation depending on who it blames for test failures. The tests are then treated as an independent implementation, and through the math of coincident errors, the arbiter feedback loop ensures that both are eventually correct (N-versions and clean room research did this with humans in the 80s). This then allows us to use less reliable LLMs to develop code, like Qwen on a MacBook Pro.
I hope to have something out on GitHub before my beach period ends (well, if I’m unsuccessful in getting a new role, then I’ll have a lot more time to play at least).
I am working on a CLI tool that will build a static web page for a small brick and mortar store. The software is FOSS and could be useful for the small store that has a lot of foot traffic, but is under served by many of the big tech offerings. The idea is that foot traffic can be increased by using a QR code placed on a banner outside the store directing them to the website that can display sales and types of items that the store offers. Pleases check out the build log for details of my progress.
I'm working on Trebella [0], a tool to help classical music students structure their practice sessions more effectively. I tried to build something similar ~10 years ago in the form of a more interactive music game, but felt like it wasn't actually that helpful for intermediate and advanced students. So this time I'm doing it in collaboration with actual music teachers and building a tool that actually helps me learn. I'd say 90% of my flute practice is done using it at this point, and I'm in the process of taking on the first arms length users in a closed beta. Please shoot me an email if you are interested in any way!
A programming language that makes your game multiplayer automatically! It integrates rollback netcode into the programming language itself, guaranteeing that whatever you code is deterministic and can be snapshotted and rolled back. Then it integrates the networking and server automatically so you can just code your game like a singleplayer game and it'll be multiplayer automatically! I've been working on this for four years now.
Two open-source initiatives:
1. https://preseason.ai Basically a benchmarking platform that measures how the top LLMs recommend devtools when prompted to build different types of web apps.
2. https://widen.dev A native Mac desktop Postgres GUI with text-to-SQL. You can even use the LLM that already comes installed in your MacOS.
I am building Bloomberry, an alternative to tools like Builtwith for finding companies that use a specific enterprise tech, as soon as we detect them
Most tools just focus on frontend tech like Shopify or Wordpress. Bloomberry shows you who uses backend tools like Hubspot, or Workday, or Gitlab for example.
Example: https://bloomberry.com/data/github-enterprise - companies that use Github
I was actually facing a huge friction problem when it came to closing clients—both at my agency and in a wholesale business I run with my family—because the whole quoting and payment process was really outdated. So, I built a software tool to eliminate that friction; it’s like a live Notion-style interface where the salesperson and client can update the quote and communicate via a public link. That same link allows for approval and payment—using cards or bank transfers, obviously via the Stripe API—and handles everything related to invoicing and sales. It ended up being really useful for my agency, too, allowing me to send clients more professional quotes with a detailed project breakdown so they can clearly see what the work entails and understand the pricing. Honestly, I’ve definitely noticed an improvement in sales.
My wife and I are working on a math/science/CS-inspired jewelry business. We try to create pieces that stand on their own aesthetically but have a hidden meaning.
We currently have two styles: lambda calculus based pieces (we depict the lambda/Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate. I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.
We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one), how to advertise, etc.
Any ideas on marketing are welcome.

I got laid off at the end of April and have been building my own personal dream tool since, it's a skeuomorphic carpentry simulator with an agent MCP. You start with real wood specs and a shop full of miter saws, router tables, table saws and the like. Think of it like Sketchup but no extruding rectangles.
It's been really fun to build with. Agents can create parametric procedures so e.g. stick framing becomes a simple function call for the next agent, building a flywheel. There is full agent-human parity in every surface, so there is a human UI for the procedures too.
Every operation is yaml, so agents pick it up pretty quickly. Agents can also file feature requests when they reach for a tool that doesn't exist. You can export to 3d printing files, video walk-through, step files, get a BOM and a cut plan, view your project in life-size with AR. There is a notion-like interface for authoring build guides... a lot going on. If you're a woodworker/software engineer you might enjoy it.
You can add the MCP to your agent of choice, send a picture, description, sketch or whatever; say "build this with Sawdust"
