Intel's Management Engine
Recent CPUs from Intel requires a binary called the “Management Engine” (Intel ME, or ME for short). This binary is one of three parts required if a business elects to use Intel’s Active Management Technology (AMT), which Purism avoids.

Dissecting the Apple M1 GPU, part I
Apple’s latest line of Macs includes their in-house “M1” system-on-chip, featuring a custom GPU.

First Atomic Clock Wristwatch
Do not be misled. The many "atomic time" wristwatches you see on the market today are merely cheap quartz wristwatches with a built-in radio receiver. The watch sets itself from 60 kHz VLF radio time signals transmitted by NIST from station WWVB near the US atomic clock in Boulder, Colorado. At least once a day…
