Talking about technology (mostly)

Today I learned about systemd-tmpfiles which can be configured with files in /etc/tmpfiles.d.

So today via What Does “VCC” Stand For? I learned that VCC stands for “voltage at the common collector”.

So today I learned that “HC” (high speed CMOS) and “LS” (low power Schottky) are two different types of logic family.

Today I read a little about Coupling and Decoupling. Apparently 0.1uF ceramic cap across VCC and Ground pins on a IC will do it.
