It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes. I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so…

So there is no technical debts ?

https://mysukari.com - A Diabetes management platform I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and…

That's so cool! Nice work!! Are you happy to share how you built and host it? How long has it taken you to get it to this point?

Thanks! I started out with a Nextjs full stack on Vercel, with db on Turso but ended up with a React frontend (next on vercel) and Go backend (selfhosted on vps).

Decided to port the backend to Go + postgres (on a Hetzner VPS), and retain the frontend on Nextjs - A lighter weight client, moving most of the compute to the backend API. Few reasons for the port: I've had a lot more success/stability with Go backends, Turso pulled multi-tenant dbs which is what I mostly wanted them for, Nextjs is getting too hard for me.

Go backend is just the std lib (1.22+ server with the nice routing) - I mostly write all the lines in this

Frontend is textbook modern react: React19,next15,tailwind4 - AI mostly writes the code in the frontend (Cursor + Cline + sequentialthinking + context7 + my own custom "memory bank" process of breaking down tasks). AI is really, really good at this. I wrote this https://image-assets.etelej.com/ in literally 2 days 2 weekends ago with less than 10% of code being mine (mostly infra + hono APIs)

I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.

The new one is browser based.

The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.

IO between the UI and worker is handled by message passing.

Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.

The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.

The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.

I am sure all of this is theoretically possible, at least.

AI bookkeeping for solopreneurs.

As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.

Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.

So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?

At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.

Working hand-in-hand with CPAs and some platform partners on this. Would love to hear from other solopreneurs or engineers who want to help build the future of financial freedom.

In my experience, "vibe coding" can produce a rich prototype very fast.

Then as scope expands you're left with something that is difficult to extend because its impossible to keep everything in the LLM context. Both because of context limits and because of input fatigue in terms of communicating the context.

At this point you can do a critical analysis of what you have and design a more rigorous specification.

Billing. Subscription plans and invoices in micro services architecture.

I honestly hate it at this point and would appreciate any reading on the topic. It's been a grueling 4 months of back and forth with a lot of mission critical business aspects to handle that I had to learn on the fly.

The Want Build System

https://github.com/wantbuild/want

https://doc.wantbuild.io

Want is a hermetic build system, configured with Jsonnet. In Want, build steps are functions from filesystem snapshots, to filesystem snapshots. Want calls these immutable snapshots Trees. Build steps range from simple filesystem manipulation and filtering, to WebAssembly and AMD64 VMs.

IndexedDB seems really cool. Never really worked with it but seems like a good option for you.

Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement. Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs. Feeling increasingly like this is a fool…

Very interesting. Maybe we can chat and explore? DM me on my X.com - it's on my HN about page - copy-paste the HN link here for context :)

I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+). In what I believe is sti…

I have just created an account and tried to use the app; either I am dumb (at this hour), or the app has a very not intuitive UI :-)

I (think I) managed to create an expression, but: 1. it takes forever, I don't know what it's doing and it's still not done 2. I have no idea how to use it, onward 3. does not seem that I will be actually able to use it, as the app requires to be subscribed to use it...

Looking forward for a how to use manual / page + a real trial period. If the app requires a subscription with this UX experience, I will be gone :-)
