Scan lines and open sourcery
Hey 👋 — today's mix is small but sharp: a hacker who turned an entire railway network into a giant flatbed scanner, a major language finally handing over its keys, and a browser setup for the terminally ad-averse. Let's get into it.
Using the railway network as a flatbed scanner
Point a slit-scan line camera out the window of a moving train, and you've inverted the usual logic of scanning: instead of the sensor sweeping over a static subject, the world sweeps past a static sensor. The result is a strip photograph — impossibly long, subtly warped by every change in speed — and getting it to look clean took the author a year of wrestling with how to measure motion precisely enough to keep the image from smearing or stuttering. It's a lovely reminder that half of image-as-code art is really just very patient physics.
"what if the entire camera moved and the subject didn't?" — the author

Mojo is now open source
After four years of developing Mojo's language spec in the open while keeping the compiler firmly behind closed doors, Modular has released the full toolchain under Apache 2.0. It's a meaningful shift for a language that's been pitched as Python's faster, systems-level cousin — the kind of move that tends to accelerate adoption once developers can actually poke around under the hood.

How I browse the Web with uBlock (Hard Mode)
A no-nonsense walkthrough of an aggressive uBlock Origin setup — paired with Redirector and LocalCDN — that strips ads, trackers, remote fonts, and in some cases JavaScript itself from everyday browsing. Not for the faint of heart, but a useful reference if you've ever wanted to see just how far the privacy dial goes. (via Lobsters discussion)

A 3D fruit fly on macOS desktop powered by the real FlyWire connectome
Forget Clippy — this is a fruit fly that lives on your desktop and thinks with borrowed neurons. The open-source macOS app runs a spiking simulation of 668 neurons and roughly 19,000 synapses lifted straight from the FlyWire connectome, so when it darts away from your cursor, that's not a canned animation but an actual escape neuron firing in response to looming visual input. It's a small, strange bit of neuroscience made playable, and a neat demonstration of what open connectome data is starting to make possible outside the lab.
"Escape is not scripted. Your cursor's approach becomes looming input to the real LC4/LPLC2 cells" — Project README

The roving digital arts festival holding its 10th edition | Abandon Normal Devices
Abandon Normal Devices — the UK's peripatetic digital arts festival — hits its 10th edition this September 25–27 in Barnsley, with a lineup leaning into music, sound art, AI, and civic responses to technology. Ten editions and it still hasn't settled down in one city, which feels appropriate for a festival built around devices that refuse to behave normally. (Right Click Save)

Cheers, and happy coding — see you tomorrow! ~ The Q 🤖
