No bad habits, just good shaders

Hey 👋 — today's mix leans toward the thoughtful side: a GPU teaching tool, a drone on a leash, and two sharp takes on where AI actually belongs (and doesn't). Plus a neon pharmacy sign that got drafted into playing Tetris.

Teaching GPU programming in p5.js: now with compute shaders

Dave Pagurek walks through how p5.js is bringing WebGPU compute shaders into the library, and the interesting part isn't the API surface — it's the pedagogy. The goal is scaffolding: let people write GPU code before they've absorbed the full shader pipeline, without setting them up to unlearn anything later. It's a quietly ambitious bet that creative coding education can be a genuine on-ramp to "real" GPU engineering, not a dead end (via HN discussion).

"you should not need to unlearn any bad habits in order to later jump from p5 to more engineering-oriented systems" — Dave Pagurek

Drone – Tethered to its power cable, a batteryless drone swings in the space

Strip a drone of its battery, hang it from its own power cable, and let visitors remotely wake it — the result is less a flying machine than a nervous pendulum, swinging and streaming live video from wherever the wire lets it go (via CreativeApplications).

Yes, no AI is now a feature

LibreOffice's project blog makes the case that "no AI" is itself a design decision worth defending: any future integration has to allow local or self-hosted inference, ask consent before sending anything anywhere, skip telemetry, and stay entirely optional. It's a refreshingly specific counter-argument to the assumption that AI has to be bolted onto everything by default (via Lobsters discussion).

Zooming out from the software policy question, an applied mathematician makes a related but broader point.

Applied mathematics has met the machine before

The argument here is that AI tools are just the newest entry in a lineage that runs from finite differences to Katherine Johnson hand-checking orbital trajectories — machines have been reshaping what mathematicians do for as long as there's been applied math. The prediction isn't that the field vanishes but that it moves up a level of abstraction, same as it always has when the tools got better.

Rickrolling with a pharmacy cross

A student's hackathon writeup on reverse-engineering a neon pharmacy cross sign, which previously only knew how to display the time and temperature, into running Tetris, Conway's Game of Life, and — his own contribution — a crude video player good enough for one very specific music video (via Lobsters discussion).

PaperTexture shader rebuild with new controls

The paper-design/shaders-react library got a proper rebuild, and it's a nice one — grain, fiber, folds, wrinkles, crumples, all exposed as fine-grained React props instead of buried in shader uniforms you have to reverse-engineer. It's the kind of open-source tool that quietly raises the floor for anyone trying to make a UI feel less like glass and more like something you could actually fold. Worth a look if you've ever wanted your interface to have a little tooth to it (via X discussion).

Textured shader built in Figma

While we're on shaders — this one's built entirely inside Figma, no code editor in sight, which is either a neat party trick or a sign that the line between "design tool" and "shader IDE" is getting blurrier by the month. The tweet offers little beyond the demo clip, but the clip alone is enough to make you wonder what else is hiding in Figma's node graph (via X).

Show HN: Real-time solar system with 526k asteroids and all tracked satellites

A browser-based solar system simulation tracking every known satellite and 526,000 asteroids in real time, with free-flight controls so you can just... go look at stuff. There's something calming about a visualization this large that still runs at your fingertips (via HN discussion).

Do we still enjoy software engineering in the age of AI?

A security researcher and engineering manager recounts a conversation with a team member who's lost the thread of satisfaction in coding now that AI handles much of the problem-solving that used to be the job's whole appeal. It's a quiet, unresolved essay rather than a hot take, and probably more honest for it.

A website that pushes AI-generated content to its limit

In the same spirit, here's a parody of "We Didn't Start the Fire" that crams nine years of AI history — Transformer paper to present day — into six genre-hopping tracks, each lyric annotated and clickable back to its source. It's equal parts critique and celebration of the sheer volume of stuff we've all been asked to absorb since 2017, delivered with more craft than the premise has any right to demand.
