This really seems to be obvious. Brazil has such a legislation[0]. However, the code for the important payment service called Pix, developed by the Brazilian Central Bank, is nowhere to be seen. Laws alone are not enough.

10 years.. But yeah. Just wait until these things can move through space with physical/gyro sensors on their own, at affordable costs. When orin nano super is the cost of an Esp32 (and the size of).

No gps, no fiber, no 5g, no jamming except microwaves. A python file and a target.

Scary times ahead.

and better guidance software. Yeah, there's a lot of room for improvement

"Traditional waypoint navigation assumes movement through a series of Cartesian positions. But in pursuit dynamics, for example, what matters is directional alignment over time"

I'm working on an open-source system called SpinStep (just search GitHub) — it's a quaternion-driven traversal framework for orientation-based logic and spatial data structures.

It’s not directly tied to geolocation, but it could integrate nicely with something like Astradia. Since Astradia provides high-fidelity attitude data without relying on GNSS, SpinStep could use that orientation stream to drive autonomous behavior trees, scanning patterns, or state transitions — all without depending on coordinates or maps. Basically: orientation in, logic out.

Would love to hear from others thinking about orientation-first autonomy or mapless navigation.

Fascinating article – a great example of J's array-processing power for concise, performant geometric computation.

It got me thinking about how different paradigms could complement this. I've been working on a Python project[0], which is a framework for quaternion-driven traversal of tree-like structures based on orientation rather than just position or order.

Essentially, J handles the low-level "how" of vector math at scale, while SpinStep-like concepts could provide a higher-level, more semantic "what" and "why" for decisions driven by explicit orientation sets and angular relationships.

It's an interesting thought experiment on combining the raw power of array languages for geometry with more specialized frameworks for orientation-based reasoning.

Well done — really enjoyed this. We could use this kind of optimization in our library[0], which builds differentiable logic networks out of gates like AND, XOR, etc.

It focuses on training circuit-like structures via gradient descent using soft logic semantics. The idea of compiling trained models down to efficient bit-parallel C is exactly the kind of post-training optimization we’ve been exploring — converting soft gates back into hard boolean logic (e.g. by thresholding or symbolic substitution), then emitting optimized code for inference (C, WASM, HDL, etc).

The Game of Life kernel is a great example of where logic-based nets really shine.

Hi HN,

I'm a solo developer working on SpinStep. It is a proof-of-concept quaternion-based traversal framework for 3D graph, trees and orientation-based data structures. I'm actively developing it and looking for contributors, testers, and curious minds.

Appreciate your time — feel free to drop questions, suggestions, or PRs!
