I'm getting back in to audio programming, starting off with Pd[1] and reading Miller Puckette's book[2]. I'm planning on writing some low-level C libraries afterwards, using The Audio Programming Book[3] as a guide

Ugh. It's time for me to start transitioning my iOS/Watch/Mac programs to be "Liquid Glass-native."

I should be able to do it with my various personal apps, but one app I've written, was done in concert with a professional graphic designer, and he is not happy with LG, so I expect that app to be a pain.

These are my apps: https://littlegreenviper.com/AppDocs/

I’m working to convert a pure services coaching business into a coaching augmented by technology. I want to keep the human coaches front and center but simplify operations and have tech/AI fill in where it helps both the clients and the coaches.

A web app for my music needs - metronome, ABC notation editor with MIDI playback and PDF render, an embedded YouTube video player with a chapter/section creator based on timestamps and a looping feature for the chapters for practicing

https://metro.scopecreeplabs.com

https://metro.scopecreeplabs.com/abc

https://metro.scopecreeplabs.com/video

Offline first, everything is saved to Local Storage. Sharing is also purely serverless - the ABC text and the video chapter defs are shared via query parameters after compression and base64 encoding.

Tech: React, Material UI, ToneJS, ABCJS, CloudFlare (Pages, Workers, D1 Storage)

Next: Add an AI assistant to the ABC editor - editing ABC text gets painful fast.

A new ping pong paddle design.

My backhand is OK but my forehand sucks. Grip styles for standard handles usually end up favoring one side or the other. I'm making a handle shape that's easier to get the blade angle right on both sides. Hopefully a couple more iterations on the 3D printer and then I can have a functional prototype made.

In particular hardware-accelerated video playback, and adding Portals.

I built a website (https://hpyhn.xyz) for hacker news users for reasons:

1. hn comments are valuable, I've spent a lot of time going through hn comments. I think there are valuable comments buried in the threads with fewer points, so it's not enough to just read top3 threads.

2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.

3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference

so I want a tool to save my time while not missing out too much on hn

I made an LLM-assisted DnD character sheet tracker! It's up here:

https://www.csheet.net/

And the repo is here:

https://github.com/igor47/csheet

If you play DnD, I would love feedback! Feel free to leave it as GitHub issues or discussion.

If you don't play DnD, you might still find the repo interesting. It's hono on bun, I render jsx server side and client side is all htmx. I use vercel's ai toolkit for the LLM interactions, which are super fun and work really well. I think this is a great use for AI actually. I've structured the code so the same services can be called either by the user via forms and routes, or via LLM tool use, so for every action in the code you can do it via either LLM or "manually".

The LLM usage is fun and interesting. What model are you using, and how much customization are you doing to integrate with the app and maintain character?

I suggest adding an export function to make the characters more portable. Maybe export to PDF as well as JSON.

Using haiku 4.5 right now. I think I could get away with even smaller models. The prompt is here: https://github.com/igor47/csheet/blob/main/src/ai/prompts.ts and my tool use is here but it's really all through the code: https://github.com/igor47/csheet/blob/main/src/tools.ts

Working on a low cost, miniature Bluetooth tracker. The inspiration was my parents keep losing (forget) their spectacles in the house. I wanted to build something that is very easy and simple to use and it was important to keep it small. SO the form factor is something like an airtag but 10x smaller which can be just stuck on to the spectacles and forget that it exists. Next step, obviously is to build a simple app that shows the location of this tracker with a range based on the Bluetooth signal strength.
