Ask HN: What are you working on? (April 2025)

A tool to address friction in B2B interactions (mostly between large companies) I've seen in my career. Main innovations are in comms and contract management. Leaning in on some hardcore dev talent in the team for the stack: there's Rust and Gemini in the mix. I'd say we're past the halfway point of MVP development

This is cool, and something I've thought about a lot, as I'm pretty unhappy with the state of CAD on Linux. The world definitely needs another open source CAD kernel, and I was toying with making my own before I decided to pursue something else.

I think the problem of finding edges can be solved by stepping back and redefining primitives. One idea I had was defining them as a 2D sketch and a transformation function along a path. A sphere would be a 2D hemisphere that rotates as it moves along a circular trajectory, with the flat side staying in place, for example. A cube would be a square That moves along a vertical or horizontal path the distance of the sides. You get the idea.

The advantage of this type of representation is that edges can only ever be edges in the 2D shape, or the path traveled by vertices. The hard part is that when you do boolean operations using primitives, you probably want to go back and turn it into a primitive representation (2D shape, transformation along a path).

2004 Lincoln Towncar. Recently replaced the intake manifold myself. Next is J-modding the transmission. Would like to replace gears with a different ratio for more power, but that will require taking it somewhere, not something I can do in my driveway.

Started my first garden this spring. Have several peppers, tomatoes, zucchini, and a few herbs.

Looking into internships and new opportunities. Been out of the profession for along while and need find my way back in.

For awhile I've been working on an MPE MIDI controller called the Mosaichord. It uses a tuning system called just intonation, where the frequencies of all the notes are related to each other by whole number ratios. I'm using a scale that has 28 notes per octave. Keys are pressure sensitive.

A few weeks ago I got a video of one of my friends playing it at a show: https://mastodon.social/@DesiderataSystems

Something I'm working on right now is trying to implement a basic on-board synthesizer so people can use it without a laptop or external hardware synth. (I added a DAC a couple hardware revisions back, I just haven't done anything interesting with it yet.)

The firmware is open source and there's a fairly detailed user manual.

This is neat! I hope this gains traction and one day becomes the norm. I hate Leetcode :/
