This toy retro synth installs and runs on esp32-s3 or p4 as an ELF file under BreezyBox firmware. It uses my work-in-progress immediate mode TUI library in C.

Web-based version via emscripten: https://mini000.itch.io/beeper

Source code: https://github.com/valdanylchuk/beeper

Demo video running on Tanmatsu (esp32-p4): https://www.youtube.com/watch?v=uCH9XYZ7QB0

The main challenge I was going for was actually to find a nice minimal set of controls for a subtractive synth. Usually there are 40-50 of them in "simple" synths; I ended up with 16.

In terms of TUI, I wanted to see if it would be practical at embedded C scale to use a modern approach similar to ratatui, Dear ImGui, or Nuklear. I am quite happy with it so far. Will keep using and extending it for more embedded apps.

I did not publish the library as a separate project yet; it is not mature enough. Feel free to reuse it via good old copying for now if you like it.

For those who remember my earlier post here about the BreezyBox ( https://news.ycombinator.com/item?id=46918429 ), a few updates from the last 6 months:

* added sshd for inbound connections * extended shell with variables, loops, conditions, tar, grep, diff * added sound component, including pico8-themed sequencer, and a few example apps * ported my self-hosting C compiler for RISC-V (rcc700) * shared a full example firmware project for Tanmatsu (p4), in addition to earlier Waveshare (s3)

Thanks for checking this out! I welcome any questions and feedback about the synth app, the TUI library, or the Breezybox firmware.

Hi HN,

I've been working on QUBE Predict, a cloud platform for drug response prediction built around graph-based biological descriptor learning.

Rather than relying solely on end-to-end models, the framework focuses on reusable biological descriptor representations that can be paired with conventional machine learning algorithms.

The platform includes:

• REST API

• Web interface

• Batch prediction

• Authentication and API keys

• Cloud deployment

The methodology has been described in a publicly available technical paper.

Paper:

https://doi.org/10.5281/zenodo.21455765

Live Demo:

GitHub:

I'd really appreciate technical feedback, especially on the representation-learning methodology and platform architecture.

Focus just doesn't cut it. I don't want Jira, Teams, Outlook, Slack, etc. sending me notifications after I've signed off of work, or if its the weekend. I find myself turning of Teams notifications on my iPhone over the weekend, and forgetting to turn it on during work hours. Apple should introduce a feature that schedules work-hours notifications, so you decide what times Teams notifications should be sent to you and during what day of the week. Shouldn't be fixed to 8h, some of us might want it to be turned on between 08:00-10:00 on a Wednesday only. Thoughts?
