I'm looking for an entrypoint to learning about quantum computing to which I'm exposed only by popular science articles and some qiskit materials so far. I understand that it's entirely possible that I'm insulated from the underlying math and implementation details, but I'm not interested in that. Considering my background is in classical programming, mostly imperative languages, what's a good book or set of other materials to get me started but with a view to eventually go deep?
I was very inspired by Michio Kaku's  on the possibilities of quantum computing and also listening to Talia Gershon's  on it.   As I come from a business &amp; analytics background, what materials can I begin exploring to prepare to learn more about the field of quantum computing? Eg. what would I need to study to understand Peter Shor's algorithm,  on physics, etc.
In .NET, what's the best way to prevent multiple instances of an app from running at the same time? And if there's no "best" technique, what are some of the caveats to consider with each solution?
