In what way does ReSharper or Visual Studio communicate Windows only?

Neither ReSharper nor Visual Studio communicate anything about their environment. That's call setting expectations. There is no expectation of what environment it's to be used with (although ReSharper sounds like c# a lot to me).

The issue with 'The Programmer's Notebook' is that the expectation is set at something like 'This is a notebook that will be generally useful for many types of programmers'. It's like the Physician's Desktop Reference. The name implies that it will be of general usefulness to anyone in that particular field.

So when I see the title 'The Programmer's Notebook', the expectation is that it will be something useful for all types of programming (embedded, linux, bsd, web, native desktop, rtos, etc).

Then the expectation is crushed because it's only usable if you have an apple device. That means a large swath of 'programmers' (whom this notebook is apparently supposed to be for) are not going to have access to it. Thus the whole thesis of the title is invalid. It's not the programmer's notebook, because many/most programmers are not going to be able to use it.

You seem to have missed my point. It's what those names don't communicate that makes them better. They don't make it seem like they're more broadly applicable than they are.

That said, the "sharp" in "resharper" actually does hint at its Microsoft nature, as it's the same sharp in "csharp"
