At least California is generous enough to require at least 25% of payroll. Most states, if you have even a single employee in that state you need to register as a business in that state (and pay associated filing fees and taxes).
This isn't really news. 15 minutes of reading about staring an LLC in Deleware and you'll find you have to register in the state you live as well - so it shouldn't be a shock you have to file in places you have employees.
1099 is definitely the way to go for as long as you can - people still get social security credit.
I have hybernation working fine with root and swap under lvm in a luks encrypted partition. Pretty sure when I set up ubuntu 16.04 or 18.04 it just worked out of the box. Though sound doesn't like to come back properly for the headphone jack and I need to rmmod/modprobe the driver.
Americans often have set of measuring spoons (https://www.amazon.com/s?k=measuring+spoons) that have 1 Tablespoon, 1 Teaspoon, 1/2 teaspoon, 1/4 teaspoon (some have 1/8 teaspoon too). As you found, a Tablespoon is an "exact" measurement and most don't use their actual eating utensils for cooking - though I'm sure at one point they were used.
Often I've found with watching cooking shows (and some of my own experience) when hosts say something like "add a ___ of blah" and then proceed to just pour it out of the container without exact measurement the reason they are giving a measurement is to give a rough approximate of how much but the exact amount doesn't really matter, though it never hurts to go towards the smaller for things like seasoning.
In terms of baking recipes (bread, cakes, cookies, etc) the exact amount matters more (chemistry or live things) but you can still be off by a bit and things will still work.
