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

Every book has a unique number used to identify them, the ISBN (International Standard Book Number). If you can figure out the ISBN of a book, it becomes an easy search term for piracy, because now you aren’t looking for a long title, you’re looking for a unique number!
Most bookstores will list the ISBN of a book on their website, so that step should be pretty easy.

Then to commit the piracy, you can often just google the ISBN + filetype:pdf and get a free PDF pretty frequently.
There is also library genesis (libgen), where you can look up pirated books via their ISBN, which has a super wide selection.
And if even libgen does not have it, you can try torrent trackers (read up more on !piracy )

Of course most of those options are legally questionable or illegal depending on where you live, and I of course would not recommend you actually perform them ;)

I like how textbooks all have ISBNs
They make pirating them so much easier!

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)

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
