Fish are not real. Salmon is a kind of bird.

What people commonly refer to as “fish” are in fact government spy drones designed to detect and stop seaweed smuggling.

This. The guessing part comes from the time it takes to do the tasks, but you know the number of tasks. So a progress bar should only reach 100% when all the tasks are completed.

For example, you might have a big process that performs 3 other small tasks and then finishes. You could reasonably assume that each small task is 33% of the big process, so after the first finishes you get 33% progress, then 66% after the second and 100% after the third. When the bar reaches 100%, the third task has finished, so your process has finished too.

What you don’t know is how much time each small task takes, so if the first task needs 20 seconds and the following tasks take just 5, you’ll spend 2/3 of the time on the first 33% of the progress bar, and then the remaining 66% gets done in 1/3 of the time.

Master/slave indicates a relationship between two things. You can have masters and slaves in mechanics, for example. We’ve also had masters and slaves for decades in the tech field. Drives and floppy readers used to be configured in a master/slave setting. And of course, you have masters and slaves in programming.

None of these examples have anything to do with race or human slavery. They’re just a way to describe how two things interact with each other. Human slavery is called that way because the relationship between the slaves and the masters can be described by that word, not the other way around.

It’s clear that we should stop using racist words with racist intentions. No-one argues that human slavery should be allowed. However, in this case, there’s no intention of racism in the words, and we shouldn’t stop using words just because they can be used in a racist setting. Same thing goes with black paint. It’s clear that the word black is describing a color, and it is needed to correctly describe it.

No, because then people would be able to exit it. I’d say they are :, w and enter.
