I'm working on a rating/reviewing website for YouTube videos, with strong search and filter functions that YouTube sorely lacks, along with good curated list building functionality.

https://www.ytdb.io/

With a strong rating weight system that can avoid (some) of the pitfalls of community ratings.

Right now videos must be added to be searchable, to comply with YouTube API rules. I'd hope that over time, with enough usage, the repository could contain many categories of highly curated content. (eg. Documentaries) that someone could find without having to browse various communities and opinions to get lists.

- A server to run TrueNAS using ZFS. Going to pair it with Tailscale and Nextcloud as a replacement for Dropbox.

- Implementing a Convolutional Neural Network in pure Python to learn how it works.

- A Open AI Whisper to an embedding model pipeline to transcribe and summarize podcasts.

This weekend I (& AI) made a little quizzing app for testing myself after watching Jeopardy.

Only put the last three games of this past season so far, but I will probably add more each day (re-runs are still on until the new season starts in September).

I'm working on a telemedicine system connecting patients with remote doctors in rural Africa.

While medical records systems in much of the developed world are still shared via fax, we think there's an opportunity to leapfrog existing systems and have a cloud-based source of truth.

I'm building Collie (https://collie.ink/).

It's a tool to help teachers detect student assignments that have been written by AI. Unlike other solutions out there, it's an entire web-based text editor that analyses not just the final assignment, but all the keystrokes used during the writing process.

My theory is that analysing the final text only is a futile struggle - billions are being pumped into making LLM text look more human, so trying to make an assessment off final text alone is guess work at best.

I'm curious what folks think! Especially teachers, devs, and anyone navigating this space...

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…

I watched your talk, very interesting! Super inventive idea, I hope it works out.

Is the name a word play with "torgnole" at all, or does it mean something?

I'm building an app for language learning with Youtube. I realized that yt probably has the largest collection of spoken language that ever existed, so I wanted to make it accessible, especially on mobile.

I'm focusing on Chinese (Mandarin) right now, because that's what I've been learning, and the language learning community on reddit likes it too. But other languages are also available.

Finally caved and built a custom AI newsletter curation platform for a friend who's been pestering me to automate his GPT news digests. Still no idea if there's real demand, but the learning experience with Cursor and Claude Code has been worth it. After growing my own newsletter to 800 subscribers, I'm convinced aggregation beats adding another newsletter to the pile. Thanks to Claude, it works way better than I sho…

Good work! I'm trying to sign up using joel@joelparkerhenderson.com to try it. Can you enable my account? Thanks!

I'm currently working on DSC, a tensor library I wrote from scratch in C++ with a PyTorch-like API.

Right now it works on both CPU and GPU (both AMD and NVIDIA) and is capable of running LLMs like Qwen, I'm currently implementing a native profiler to trace CPU and GPU kernels and then I'll work on speed. Goal is to be competitive with PyTorch eager by the end of the year.
