IRZ pipeline showing two frames compared into a motion map that later rendering shaders interpret

The shader moves nothing. It paints what moved

Maxime Heckel does not move objects in a shader: he turns differences between frames into masks, flow and velocity, then draws with those traces. The cost follows the pixels being processed.

Comparison between syntax highlighters that emit token spans and Microlighter keeping one text node with CSS ranges

Syntax highlighting can now live outside the DOM

Microlighter colors code with CSS Custom Highlight instead of wrapping every token in spans. We measured the real payload, DOM behavior, 37 grammars and all ten themes.

Five IRZ tests showing which accounting errors are caught by hledger, Git or a bank balance assertion

Your books can live in Git. So can the trouble

An hledger journal is readable, diffable and exportable. We induced five failures to see what plain text catches, what Git improves and what neither one solves.

DIN-rail Edge Link enclosure built around an Arduino UNO Q

A good retrofit starts by leaving control alone

Edge Link shows how to add telemetry, a UNS and local AI to old equipment. Its current prototype is mostly upstream: remote control is exactly the part that should not be treated casually.

Nicola Cimmino’s PLC14500 Nano board based on the Motorola MC14500B and covered in diagnostic LEDs

One bit was enough to start a pump

Motorola’s MC14500B was not an eight-bit computer with seven bits amputated. A one-bit result register matched the questions industrial control kept asking: switch closed, timer done, motor on or off.
