Nauticuvs – pure-Rust curvelet transform for SAR sonar, by a self-taught dev

Hacker News - Sat, 03/07/2026 - 6:15pm

Published today: https://crates.io/crates/nauticuvs — a pure-Rust Fast Discrete Curvelet Transform (FDCT via wrapping, Candès/Donoho 2006).

Curvelets obey parabolic scaling (width ≈ length²), making them significantly more efficient than wavelets for images with curved edges. For side-scan sonar — hull shadows, seafloor targets, debris — this means better denoising and edge enhancement at the same coefficient budget.

The personal context: I'm a sailor. I worked in Congress as a special assistant to a congressman and in campaign consulting — I've seen firsthand how bureaucratic systems slow down or block tools that could save lives. In 2024, Rosa and Charlie Brown went missing at sea. The Coast Guard declined to run a backdrift analysis. I know exactly what tools could have helped, and I know exactly why they weren't available to the volunteers who needed them.

I was diagnosed with ADHD, dyslexia, and dysgraphia as an adult. I build software to compensate for gaps I've experienced myself — and this crate is the signal-processing foundation for CESARops: a full open-source SAR coordination platform with drift prediction, search planning, and sonar analysis, free for civilian and volunteer SAR teams permanently.

(Separate project: Wayfinder — an ADHD-friendly file naming and organization tool I originally built for myself, being expanded for school-age kids.)

Looking for: Rust contributors, DSP specialists, SAR professionals, technical writers. Issues: https://github.com/festeraeb/nauticuvs/issues Sponsor: https://github.com/sponsors/festeraeb

Show HN: Modulus – Run multiple coding agents with shared project memory

Hacker News - Sat, 03/07/2026 - 5:31pm

Hello HN, we're Jeet and Husain from Modulus (https://modulus.so) - a desktop app that lets you run multiple coding agents with shared project memory.

We built it to solve two problems we kept running into:

- Cross-repo context is broken. When working across multiple repositories, agents don't understand dependencies between them. Even if we open two repos in separate Cursor windows, we still have to manually explain the backend API schema while making changes in the frontend repo.

- Agents lose context. Switching between coding agents often means losing context and repeating the same instructions again.

Modulus shares memory across agents and repositories so they can understand your entire system.

It's an alternative to tools like Conductor for orchestrating AI coding agents to build product, but we focused specifically on multi-repo workflows (e.g., backend repo + client repo + shared library repo + AI agents repo). We built our own Memory and Context Engine from the ground up specifically for coding agents.

Why build another agent orchestration tool? It came from our own problem. While working on our last startup, Husain and I were working across two different repositories. Working across repos meant manually pasting API schemas between Cursor windows — telling the frontend agent what the backend API looked like again and again. So we built a small context engine to share knowledge across repos and hooked it up to Cursor via MCP. This later became Modulus.

Soon, Modulus will allow teams to share knowledge with others to improve their workflows with AI coding agents - enabling team collaboration in the era of AI coding. Our API will allow developers to switch between coding agents or IDEs without losing any context.

If you wanna see a quick demo before trying out, here is our launch post - https://x.com/subhajitsh/status/2024202076293841208

We'd greatly appreciate any feedback you have and hope you get the chance to try out Modulus.
