The "Liberate the Machines!" book is starting to be available so I made a page for it even if it hasn't had a launch moment yet.

Just in ! Another lesser-known text by Whitehead, in a nice first edition from 1934.

These esp32 boards with ethernet are great but it took a while to get the first one working.

From old and unloved books on cybernetics and electronics, the accumulative drive seems to have shifted towards equally old and unloved books on chemistry and solid-state physics.
