Had someone contact me because a browser interface was âdownâ and it was actually a cert issue. It surprised me that in an IT context, this person didnât have a basic understanding of SSL certs. They didnât even know how to add a cert exception.
It got me thinking, what basic ubiquitous things am I a dumbass about outside of IT?
Ive seen lots of âfun factsâ compilations, but it would be better to get a wide range of subject suggestions that I can spend 30 minutes each or less on, and become a more capable human.
Like what subjects would plumbers consider basic knowledge? Chemical interactions between cleaning products and PVC pipes?
What would an accountant or a landscaper consider to be so basic its shocking people can live their lives without knowing any of it?
For most areas of expertise, its difficult to know even what the basics are to start with.
This one can detect voltage with a single lead and also works as a voltage meter if you use two leads: https://www.benning.de/products-en/testing-measuring-and-safety-equipment/test-equipment-voltage-tester/voltage-tester-duspol.html
It also has an inbuilt motor to distinguish leaking voltage from continuous AC.
Sorry if I didnât use the correct English terms and that wasnât clear enough.
In Germany you simply call it a Duspol and every electrician knows what you mean. Didnât research enough into the English description but it seems itâs a two pole voltage tester with one pole voltage detection mode.
