Working with a group of friends on a "microcontroller-for-makers" kind of thing called the MakerPort. (https://makerport.fun) Sort of similar to an Arduino or micro:bit, but uses the MicroBlocks programming editor (https://microblocks.fun) created by John Maloney, who was the original team leader for Scratch at MIT for 11 years. The hardware includes an mp3 player, I2C ports, accelerometer and true capacitive touch sensors.

I’ve been working on http://www.13radar.com for the past 4 months, and we launched about two weeks ago. The platform tracks hedge fund portfolios in real-time based on SEC 13F filings.

I’m responsible for product research, analysis, design, development, and promotion. Most of the workflow was powered by AI tools — more than 60% of the research, design, and coding involved AI assistance. Initially we used Bootstrap for responsive design, but later switched to a lighter TailwindCSS framework.

Right now traffic is very low (just a few dozen users per day), and I’m trying to figure out whether that’s a product issue or simply a lack of promotion. Honestly, it’s a bit discouraging, but I’m hoping to learn from feedback and iterate.

Curious if anyone here has experience growing early-stage products with niche financial data — how did you approach the balance between product refinement and marketing?

I finally started modding a total war game (Warhammer 3). I played the series since the very first title, Shogun and I always wanted to improve the control over units and add my custom AI to not micromanage everything, but assumed it would be too time consuming and distracting from my main work. And well, it likely would have been.

But thanks to LLMs, I finally decided to give it a go and got something basic working in a short time, hurrey for AI assisted coding!

Feels empowering to be honest. No idea if I will really implement the main ideas, that I have since a long time, but I know that I can now if I want to.

Working on a CLI tool called xpire which can add expiry dates to filesystem structures: https://github.com/benibr/xpire Idea is to use filesystem specific structures (eg. snapshots) if possible to prevent long treewalks for searching and store the dates in the filesystem itself not a seperate database. It's written in go and currently supports btrfs snapshots and zfs datasets.

I wanted to give anyone the magic power to make himself an FPS game of their place (appart, museum,ect...). Still not perfect but it's light and my 3D editor is simple enough for anyone. - No coding. - And no need for Unity or Unreal.

==> Here is a photo of the Editor : https://ibb.co/FC9Hzj2

==> website with an example of a FPS visit https://free-visit.net

Please be honest, tell me why I don't have traction.

This is a cool idea! So I think, unfortunately, you are competing with automated tools like https://poly.cam/ My cousin-in-law produces music videos, and he'll take a polycam of sports cars (or even people!) and add them to his videos, it's powerful and instantaneous. No 2-3 day wait time.

It's great that you're working on this. If you want to continue on this, I'd consider: - Cleaning up the design of the website-- it looks kind of crappy. Get an AI agent to clean it up for you, it's better to look like "generic professional website" rather than "crappy amateur". - Use the more common words for creating 3d models. A "Visit" sounds like an experience, but what you're really making is a "scene", or a "spatial capture", or a "floor plan". - Maybe try to figure out a niche. Is your niche that people can edit this the 3d object afterwards? Or is the niche integration with video games? You gotta find something that doesn't directly compete with polycam.

Thank you civilian for your answer and hints. It's funny I though matterport was more like me. Because both of us make " virtual reality".

tmilard 11/10/2025||

I think You are right It's a bit idiotic from me to be cautious and say 'result in 3 days'. I could say 4 Hours now.

And yes.It's not 100% automatic. I agree, my low point.

Built an in-browser AI managed spreadsheet. https://banker.so/

Too many things I wanted to analyse went to nothing because I was too lazy to fetch information and the put it inside a spreadsheet cell by cell. So I developed this to help me extract docs into spreadsheets while also having access to the web.

Now working on a vibe-coded version of it where instead of showing a spreadsheet, it will be able to generate data-focused tiles and apps

I was working on a iPad-focused Dungeons & Dragons app focused on the Dungeon Master called Campaign Codex but I got a little bored with building CRUD apps.

Decided to pivot and start learning about databases and their internals more. Currently pulling down Clickhouse and reading some code along with the reading the book Database Internals by Alex Petrov.

So I'm technically not "working on" an app...I am working on myself to branch out and attempt to specialize a bit more as I progress in my career.

Any advice/papers/books to read is very welcomed!

Building native applications for iOS, Android and Huawei devices in Haskell.

This sounds very interesting. You say “native” but miso generates JavaScript, right? I’m not familiar with mobile development. Can you run JS natively on mobile devices?

dmjio 11/10/2025||

Yes, miso uses the JS backend in GHC, and mobile phones have embedded JS interpreters (e.g. JavaScript Core). These interpreters can access native libraries to draw native views, or access native device APIs.

Projects like lynx and react-native automate this process using something akin to node-gyp, exposing kotlin / swift libraries via C ABI w/ a JS API. Miso accesses the kotlin / swift native modules by FFI'ing into the JS that exposes them.

The JS doesn't get compiled, but on Android it does get JIT'd. So it's "native" in the sense that the views drawn are native (not WebViews), and the device APIs are native, but not "native" in the sense that it's compiled.

tome 11/11/2025||

That is very interesting. I never knew that JS could access native APIs. That's very promising for compilers that can generate JS, like GHC!

Working on a phone app that streamlines household management for unmotivated losers (like me) so that they stop wasting money (wasted food) and time (procrastination)

Working on an app that helps me (and other people) do household management on autopilot. It helps me manage things, food, expiration dates, shopping, chores, and I get notified periodically to review my lists. I waste way less food and I actually do my chores instead of procrastinating. https://okthings.app

strofocles 11/10/2025|

It looks like you have to do a lot of data entry when you buy things, no?

Parazitull 11/10/2025||

Yes. How i tried to solve it: you have a shopping list where you can add things on the fly. These things will need to be categorized (food, household supplies etc) at a later date, which is when the review is due for the "Uncategorized" category.

Generally, i tend to buy the same things, so the "big" data entry job happens only once.

Learning that RCS is even more of a monstrosity and a lie than I thought a few years ago. Yikes. Lots of groundwork a decade ago setting the stage for "the carrier creates a common service anyone can interact with" (like sms/mms currently do, which would be great) but in practice it's pretty much 100% "only the carrier app or Google/Samsung messages has access to literally any of it".

Yeah I'm not gonna touch it and I'm going to actively encourage people to disable it. Use signal instead.
