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.
I’m constantly amazed at how many people don’t understand the concepts of basic finance and how compound interest works.
Years ago, I brought my laptop with me to buy a car so I could plug all the numbers into a quick amortization schedule. The sales person offered me a choice of $1,500 cash back or 1.9% financing instead of the typical rate a few percentage points higher.
I plugged the numbers into my spreadsheet and saw taking the cash back would cost me a couple grand more than the lower finance rate. When I told him I wanted the finance rate instead of the cash back, he mentioned that I was the only person he’d seen not take the cash back.
Maybe he was pulling my chain, but in my experience, the average person doesn’t know what compound interest is, let alone what an amortization schedule is.
Have you told this story before, possibly on reddit? I swear I’ve read this verbatim including the part about the laptop and “I was the only person who took the lower APR.”
Maybe, but it would’ve been years ago.
With each year that passes since the re-telling it gets exponentially more interesting.
The interest in this story is definitely compounding.
Could just be we’re old as fuck to the point that we find amortization schedules and saving money interesting.
Thanks! excellent suggestion.
You can also use an interest calculator or multiply the payment by the term length to see how much over the purchase price you’ll pay in interest.
This is why it’s important to haggle over the purchase price and not the monthly payment. Never ever negotiate over the monthly payment, or you’re likely to get stuck with a 96-month loan at 23% interest.
My mother in law bought a truck the same week I bought my car. I mentioned that I got a 1.9% interest rate. She got a 22% rate!!! I was absolutely floored when I found out what she did.
22% is insane, that should be illegal honestly. Pretty much bought it on a credit card.
Yeah I was absolutely disgusted when I found out. It made me realize that there’s definitely a “poor tax”. If you don’t have good credit and/or aren’t informed enough to pay attention to interest rates, you’re basically going through life on hard mode.

I believe knowing a little bit on how a car works helps you understand why maintenance is important or from getting scammed at mechanics, I loved old commercials like these that explain in such an easy way. https://www.youtube.com/watch?v=yYAw79386WI
Some skills I wanna pick up is how to micro solder, I deal with a lot of tech and sometimes you just need a type c port replaced and soldering iron is not the easiest tool for tiny pins.
Learning about cars, engines and motorbike maintenance at this stage in life really opened my eyes. I could have easily been a mechanic or an engineer if I had the access to this knowledge when I was younger.
Now I do as much of my own maintenance as I can, and I’m pretty sure my engine will hit 400K before I start getting serious issues. None of it is overly complicated or difficult, and saves me money in the short and long term.
I was fortunate to have a dad who had the tools, space, and time to teach me how to do repairs, with the things he taught me I can save a lot of money buying a beat up car and fixing it up for usually 1/3 to half the price of a used one.
Good news, the broken component is a common 2 dollar chip!
Bad news, it’s an SMD, and in the middle of a giant block of plastic and 2 more circuitboards.
