People care less about the dollar value than about reconciling. If there is some external system they should match, they really want it to match exactly.
> A shocking number of people ... are unaware of how many decimal points of accuracy their local tax code requires to calculate
A shocking number of people who create tax codes have no idea how many decimal places they are using.
It's probably better now, but I recall having to reverse engineer the tax tables to figure out how many decimal points of accuracy were used, and what rounding rules were used, so we could match their numbers.
These numbers would change from year to year, with no change in the underlying tax codes.
I think many of the dating sites started that way. That's why they were better in the beginning. But eventually, they go public, or get acquired, and end up getting run by people who are bottom line focused.
The problem with leet code is what it really measures is how long you have spent on leetcode. Yes, you can solve the problems if you have experience, but you are not going to look as good as someone who had done that specific problem on leetcode and could just write down the optimal answer.
This was great science. Hypothesis, test, and attempted confirmation. Too bad it's not superconducting, but the process worked the way it is supposed to.
Why replace? So you don't have downtime. If it breaks now, everything may be off until they replace the system. That could be months of no classes, which would be much worse than spending money to replace.
If you start now, and finish before it breaks, you don't have to have downtime.
Nothing shows this like the switch from showing recommended books/products to showing ads.
Ads generate more revenue today, but I can't find good books to buy an Amazon, so I go elsewhere.
It's clear which is better for the customer (and for Amazon long term), but they can't give up on the revenue stream, even if it will eventually kill them (since it drives their customers to other platforms, and provides a place for competitors to grow).
