https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag t…

An idea for more complete coverage: have 2 of them, and invert their intervals, such that one and only one is always on

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…

The UI was a little unresponsive on mobile, and when I opened the "Media" page on desktop I got multiple block rendering errors. Opening the console reveals a syntax error (missing ] after element list) and some type errors.

Also, it looks like you have to get the subscription to use it in any way? It's hard to gauge whether it is for me or not if I have no way to trial it. I found the UI a bit confusing too, I was not sure what I was supposed to do after logging in. As another commentator mentioned, it's asking me to set a reference language but I see no way of configuring it.

Is 4 on 1 off really the best strategy? Seems like it just makes it a 20% chance that the thieves detect the AirTag, right?

Taking on a fun technical challenge, building a distributed database to serve the needs of Actor State saves in Orleans. Using the guarantees around actor placement to implement something optimal for its needs.

Much cheaper to hire a VPS with attached local storage, than to use an external database and a lot quicker too.

A tree cutting tool. Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree. The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side). I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping…

That’s a great idea, but so much liability if the user is an amateur and follows steps incorrectly

This is the kind of thing that makes me love HN. An idea I would never have thought of, with an immediately obvious use in multiple ways (fall path plus ideal lumber cutting?), probably very difficult, yet being tackled with one implementation already... and spoken of quite humbly.

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…

Is this just for Type 1 or would type 2 work well also? Seems like it would?

Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture). One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the progra…

Have you looked at Kernel and wat? They use a fundamental operator (vau) to make macros, instead of a special form: https://github.com/manuel/wat-js

maru has this vau operator implicitly, rather than explicitly: https://github.com/attila-lendvai/maru

I’ve been making photography software as an indie developer for a bit over a year now: https://heliographe.net A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline. If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,th…

Hobby photographer, I shall check this out! :)
