Because paying a few grand a year for a certificate somehow makes your software more trustworthy

What if there are no crappier cars on the road?

Because even a long (64-bit int) is too small :)
A long can hold 2^64-1 = 1.84E19
A double can hold 1.79E308

Double does some black magic with an exponent, and can hold absolutely massive numbers!

Double also has some situations that it defines as "infinity", a concept that does not exist in long as far as I know (?)

A BigDecimal?

Doubles have a much higher max value than ints, so if the method were to convert all doubles to ints they would not work for double values above 2^31-1.

(It would work, but any value over 2^31-1 passed to such a function would get clamped to 2^31-1)

Ive never used githubs CI/CD, but gitlab has quite a large ecosystem for its CI/CD.
Seems to me like you could use gitlab as a one-stop-shop to host everything from your code to your artifacts and containers, if you are willing to pay for those fancy features

Free is able to just do basic CI/CD for like 250 minutes a month, or unlimited via your own runners/build servers, thats about it

I dont post my code to github because I would rather use gitlab

We are not the same

I actually have aphantasia :)
I get open-eyed distortions and wavyness, and can see some images with my eyes closed. I have very little control over what I see, and it is more like short glimpses, but it is tons more interesting than the black void I usually stare into with my eyes closed!

LSD

I just use my regular wrench and say "click" out loud when it feels nice and tight

Depends, how much do you care, and how good does your car still look?
If you drive a pristine car that you plan on selling eventually: get it done at a bodyshop.
If you drive an older car or plan to keep it until it dies, and dont care about the looks too much: chrisfix has some good videos on working with a paint pen

If you drive a 20 year old car in the rust belt: lol
