Two things:

1. Software: An OS that masquerades as simple note taking software.

Goal is to put an end to all the disparate AI bullshit and apps owning our data.

I solved context switching for myself ages ago and now I'm just trying to productize it outside my 3 companies internal usage.

It also solves context switching for AI agents as a byproduct.

2. Ethics: Give Ai and proto-Agi a reason not to kill us all.

An extremely minimal, empirical naturalistic moral framework that is universally binding to all agents so AI won't kill us all. I view the alignment problem as a epistemic moral grounding issue and that the current pseudo utilitarianism isn't cutting it. Divine command, discourse ethics, utilitarianism, deontology they are all insufficient.

An app to help you split individual receipts with a bunch of people: https://demo.snapreceipts.fyi/ Mainly used by my friends right after we have a group lunch or dinner. You just upload a pic of the receipt after a meal and it parses out the items. We assign who got what and it calculates who owes what. Makes the receipt splitting part super easy.

How is the text extraction done? Tesseract?

I just use an LLM with a prompt (pls dont hate). Found tesseract to be very bad for text extraction.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

Ha so cool, would love one for in my bedroom ;-) I know of a Dutch company doing something similar. Focusses on pest detecting/mitigation in greenhouses atm: https://www.pats-drones.com/

Yeah, what they do is very cool. Not sure how far they are in the development but the videos are super cool.

I am working on a time tracking app for tasks. I built it because I want to gain a better understanding of how I spend my working days. It's meant to be very simple. Everything is stored locally and requires no login. I don't currently plan to sync it with any backend. This isn't something that can be used to track employees — it's just for personal use.

Playing with motion amplification to see if we can predict heart/respiratory rate of my newborn. I shot a few 4k videos of him sleeping as test data and working through some algorithms from published papers.

On parental leave with my third. We are on month 4 so I have (a bit more) free time in the late evenings after we put the older ones to bed.

I'm copying the Puppeteer / Playwright client API to run in a Chrome extension using the native Chrome extension APIs.

It is possible to run Playwright inside a Chrome extension, however, it requires the Chrome DevTools Protocol (CDP) to automate a browser which really hurts the user experience, is very slow, and opens security vulnerabilities. Chrome extension APIs can accomplish maybe ~85% of the same functionality as CDP or Webdriver BiDi -- it isn't complete because of security features which shouldn't be bypassed anyhow. For example, instead of calling a function in a content script with 'script.callFunction' with Webdriver BiDi in Playwright, a function is called with chrome.scripting.executeScript(). It will be 2 or 3 more weeks before I post a PoC.

This is following my work using VSCode's core libraries in a Chrome extension exactly as they are used in an Electron app to drive VSCode and Cursor. The important part is VSCode's IPC / RPC which allows all the execution contexts and remote runtimes to communicate with each other. [0] This solves many problems I have had in the past automating browsers with a Chrome extension.

I'm developing another social listening tool: listening4 and that's how I stumbled upon your post, haha. Unlike current tools, it's based on semantic matching rather than keywords, and it also supports AI filtering.

For the past two days, I've been working on a localized listening feature, which means matching posts in specific languages only.
