When we throw up our hands and say none of it matters, we're doing the fascists’ work for them. They don't need to hide their corruption if they can convince us it's pointless to look. They don't need to silence truth-tellers if we've already decided truth is meaningless.

Have you ever wanted to debug your device over USB-C?
(I’m talking JTAG/SWD, not just USB!) If you already have a USB-C connector, there’s no need to have an additional connector to program!
Started as a twitter thread ages ago, but I've cleaned it up and added more info!

This is one of the neatest gifts I’ve ever received. It’s a rug that looks just like one of my weather station PCB’s!
Here are pictures of the PCB and the rug. Oh, and did I mention some of it glows in the dark?!?!?

over the last year, i've been reverse-engineering and documenting old Seagate hard drives from the 1980s. the latest one is this ST-296N from 1987, which is a SCSI drive that can store 85 megabytes.
