Since Firefox does not support split mode for extensions in incognito mode, extensions that use split value for incognito key inside manifest.json configuration file might not be (side)loaded at browser startup.

One solution is simply removing incognito key from manifest.json:

sed -i "/^\s*\"incognito\":\s*\"split\",/d" manifest.json

I figured this out when running Debian Buster with Firefox 68.2.0esr with webext-ublock-origin package since the browser did not load uBlock Origin.

After upgrading to a recent kernel, eg. 5.2.4, starting of SSH service at system startup (boot) was failing, and succeed after some time: greater rhen 1 minute.

After looking at dmesg SSH managed to start after crng init done.

# dmesg |grep random

Capacitor code — Guide

Capacitor values are usually standardized: .10, .22, .33, .47 and so on. However, you might occasionally find an unusual value such as 0.15 or 0.27.

The codes below are generally found on ceramic (little round discs), MLCCs, and mylar (chicklet) capacitors, which are not polarized, that is, there are no positive and negative leads.

Usually the first two digits of the code represent part of the value; the third digit corresponds to the number of zeros to be added to the first two digits. This is the value in pF.
