Yeah, fair enough. To my mind I guess I don’t think of array indexes as an example of actual zero based numbering, simply a quirk of how pointers work. I don’t see why one starting from zero has anything to do with the other starting from zero. They’re separate things in my head. Interestingly, the article you linked does mention this argument:

Referencing memory by an address and an offset is represented directly in computer hardware on virtually all computer architectures, so this design detail in C makes compilation easier, at the cost of some human factors. In this context using “zeroth” as an ordinal is not strictly correct, but a widespread habit in this profession.

That said, I suppose I still use normal one-based numbering because that’s how I’m used to everything else working.

Indexes start from zero because they’re memory offsets, but array[0] is still the first element because it’s an ordinal number, not an offset. It’s literally counting each element of the array. It lines up with the cardinality—you wouldn’t say ['A', 'B', 'C'] has two elements, despite array[2] being the last element.

That 10Gb link is almost certainly oversubscribed, though. You don’t actually have 10 Gb of dedicated constant bandwidth, you just have access to 10Gb of potential bandwidth. You’re unlikely to saturate that link very often, so you won’t notice, but it’s shared with other people.

It’s different from Google or any other company paying for bandwidth that’s being actually used, not just a pre-allocated link like your home internet.
