What things am I a dumbass about? (lemmy.nz)

Had someone contact me because a browser interface was 'down' and it was actually a cert issue. It surprised me that in an IT context, this person didn't have a basic understanding of SSL certs. They didn't 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 'fun facts' 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.

Start with the hakko 888 or the weller equivalent. Learn how to solder big stuff first like tinning wires without burning up the insulation, big through hole joints according to the nasa guidelines, bell splices etc. it’s easier to see and judge how things are going with big stuff because you can see it better.

Use different tips to see what they do.

Remember that soldering is just brazing. You’re joining two metals by introducing a third.

Don’t start with a project you want to finish, just join a bunch of junk together, pull parts you don’t care about from old circuit boards and put different parts in their place.

Make little sculptures out of your trash.

Cheat with different kinds of flux till you don’t need to anymore.

Do the same things with smd parts.

It takes a long time to get good at soldering and no matter what anyone says you can’t just jump past the iron to hot air.

I mean, it’s possible. You’ll just never be able to fix mistakes or bridges you make with the hot air.
