I've been collecting and digitizing vintage print advertisements and publishing them ( https://adretro.com ). I have tens of thousands of ads in the collection and it would take me many lifetimes to complete, but I've been using AI to extract and catalog the meta data. I can get through about 100 ads/day this way. One of my favorite ads, a computer from 1968 that "answers riddles": https://adretro.com/ads/1968-digi-c…

Super cool project! The website looks great too. Some analytics would be amazing. Not sure why but I think it would be really interesting to see the data in aggregate from various perspectives, e.g. what were the most popular add types by year or by publication.

Thank you! Yeah I agree, I'm hoping I'll see some interesting trends I can write about.

What a neat idea! I'd second the person requesting a timeline view.

Cool thank you! I'll work on this.

An intent-based Linkedin B2B lead finding tool that evaluates tens of thousands of comments in small thematic niches to find prospects that have a certain problem, and are actively looking for a solution. I just finished building the backend side of the tool, and released it to a group of early customers to find out how well it performs. It's a really fun engineering problem to cut through tons of spam, bullshit, and hustle porn, and find the few gold nuggets in the comment sections.

I was reading a lot of technical books and kept highlighting things I wanted to remember — but I rarely went back to review them. The notes just sat there, on my Kindle or in the reading app.

So I started building something simple: a tool that lets me turn highlights into flashcards with as little friction as possible.

Just select text on your iPhone, share it with the app, and it creates a flashcard using AI — a Q&A pair and a short summary. You can browse cards in the app, or show them on your Home Screen, Lock Screen, or watchface of your Apple Watch.

This is my first iOS app, and building it has been a great learning experience. I’m using Supabase for the backend which have been mostly great.

Working on a mathematical model to quantify what is theoretically possible for humans to bridge all fragmented theories across psychology, mental health, productivity, economics, and more (similar to what Shannon did for Information theory).

It stems from my struggle to keep up with the feeling of overwhelm with so many things to learn. Currently working on organizing all of my thoughts into a coherent theory.

You can check my blog to learn more about my journey and the theory = https://www.moderncynicism.com/about

This is a great idea!

I am building a device that helps me - and hopefully others - learn how to play a brass instrument. When picking up the tenor horn I started by making flashcards. On one side there was the note, and on the other side the fingering was shown. But this was a cumbersome way to learn, and I wanted faster iteration to get this into muscle memory. So - to procrastinate - I made a device with speakers, microphone and a small lcd screen. It is currently showing the notes and fingering automatically. But I am implementing a fast fourier transform to pick up what note I am playing to show whether it's the correct one or not. FFT for a brass instrument is not straight forward as there are many frequencies being played, but I think by tuning it - it would be a very fast and gamified way to learn an instrument compared to playing scores.

An "JIT interpreter" for Emacs Lisp [1] with Graal Truffle [2] in Java. And it is really amazing how the frameworks these days simplify building a JIT runtime for a language. Currently I'm working on a pdump[3]-like feature for it. [1] https://codeberg.org/gudzpoz/Juicemacs/src/branch/main/elisp [2] https://www.graalvm.org/latest/graalvm-as-a-platform/languag...

That's great. I will like to be part of your team
