@xerz @xerz understandable. Unfortunately there are too many moving parts to account for when you don't manage the whole lifecycle of the VM. My issue tracker of the old-Boxes is filled with "Boxes doesn't work on environment X, Y, Z", etc... often I couldn't even reproduce those issues myself. This was a massive time sink.
With the time I have, I can only afford to support some of the possible use cases.
Just did some training related to cyber attacks and it referred to any task to defending against such attacks as "Cyber Tasks" so I will be calling all my tasks cyber tasks from now on

🟢 Your smartwatch's green light has a 90-year-old secret origin.
That tiny LED is photoplethysmography (PPG), an optical trick from 1937. Physiologist Alrick Hertzman at St. Louis University pointed a light bulb and photocell at a finger and watched the pulse show up in the changing light passing through the blood.
Same principle, different scale: it now runs hospital pulse oximeters and every fitness wearable. Green light near 520-530nm is strongly absorbed by hemoglobin, so when your heart beats and floods the wrist with blood, less light bounces back to the sensor. Count those dips and you have a heart rate.
One bit of history worth knowing: the rabbit's-ear version of this experiment belongs to Molitor and Kniazuk at the Merck Institute in 1936. Hertzman's landmark 1937 paper measured human fingers and toes, not a rabbit.
The tech also keeps shrinking. In April 2025, SCIVAX and TSLC in Japan announced the world's smallest PPG sensor head at about one square millimeter, a tenth the conventional size. Miniaturization like that is why rings like Oura can get so thin.
