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.

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!

To the unaided human eye, space is largely a muted void. Stars pierce through the darkness like pinholes in velvet, but much of the grand tapestry—the swirling colors of nebulae, the fiery birthplaces of stars, the delicate filaments of distant galaxies—are invisible. Our vision, evolved for survival under a sunlit sky and on a green-blue Earth, isn’t tuned to perceive the vast electromagnetic chorus the universe sings in.

Although space may appear subdued to our eyes, that doesn’t mean it isn’t beautiful—only that we need to borrow better eyes to truly see it

Noted — but honestly, that's somewhat expected. Vibe-style coding often lacks structure, patterns, and architectural discipline. That means the developer must do more heavy lifting: decide what they want, and be explicit — whether that’s 'avoid verbosity,' 'use classes,' 'encapsulate logic,' or 'handle errors properly.'

It's interesting to note, that the Universal AC in “The Last Question” did not hallucinate an answer.

Instead, its response—"INSUFFICIENT DATA FOR MEANINGFUL ANSWER"—is a model of intellectual honesty.

OpenSCAD is an underrated but powerful modeling tool, especially for developers and engineers who appreciate precision and code-driven design. It has a low barrier to entry — the syntax is simple, yet expressive — and with just a bit of practice, you can build tight, parametric models that are incredibly robust.

One of its standout features is the `hull()` function, which computes the convex hull of multiple shapes. When used skillfully, `hull()` becomes more than a geometric operation — it’s a design primitive that lets you smoothly bridge components, create enclosures, and generate complex organic forms without manual sculpting. It's like having a smart “connective tissue” for your model.

If you're comfortable with code and want exact control over your 3D prints or CAD designs, OpenSCAD delivers precision with minimal overhead. It rewards clean thinking and composability — making it ideal for rapid prototyping, parametric part libraries, and even mechanical design.

>>Can this be mitigated by putting the cables under ground?

Yes, it can (apparently), since these are mostly indirect effects of atmospheric vibrations (aka 'wind'). The vibration itself isn't usually the root cause of a blackout — but it sets off a chain reaction that leads to one (line contact/short circuit; conductor breakage; overcurrent & load shedding; protection system malfunction or overreaction, etc.)

The fewer resources we dedicate to grid resilience and modernization, the harder black starts become. And as grids get more complex and interdependent, recovering from total failure becomes exponentially harder.

A rare but sobering opportunity to reflect on something we usually take for granted: electricity.

We live in societies where everything depends on the grid — from logistics and healthcare to communications and financial systems. And yet, public awareness of the infrastructure behind it is shockingly low. We tend to notice the power grid only when it breaks.

We’ve neglected it for decades. In many regions, burying power lines is dismissed as “too expensive.” But compare that cost to the consequences of grid collapse in extreme weather, cyberattacks, or even solar storms — the stakes are existential. High-impact, low-frequency events are easy to ignore until they’re not.

Reinstate chronological order. Problem solved.

I think it's time the biggest players in the software industry step up, maybe through a formal consortium. This model would make sense because they benefit the most. Big tech companies rely on CVEs to secure their own products;

They have the means. With their massive revenue and dedicated security teams, these companies could easily fund CVE operations. A consortium approach spreads responsibility fairly;

Shared responsibility, shared benefits. Security is everyone's problem.

Please accept my critique to Smithsonian Mag made in good faith: never use the word 'mysterious' [a nod to the magical thinking] in a science context. Really looks like CNN-ish dark pattern. The URL slug has a better word choice:
