comment Modelling a complex schedule of work
Is there a cost (money or time) to go to the exchange?

comment Fuzzy algorithm for grouping data
It sounds like you may be looking for some Pattern recognition assistance. It's a pretty big field. Cluster analysis might help, but it's not a casual "write up some code in 10 minutes" sort of thing.

You MAY use these terms :-)

comment Multi application handling from single GUI
Those are probably not separate programs, but separate modules within your main program.

comment Use case for async/await?
You certainly can use an event driven scheme, but why bother? I suspect your code would be more difficult to maintain.

What problem does this application solve?

comment Syncing file data and form data uploaded at separate times
Upload the file, have the server generate the GUID & return it as a string. Include that string with any other updates.

comment Syncing file data and form data uploaded at separate times
I'd use a GUID. Filenames are not necessarily unique and Math.random might have collision issues, depending on what rounding you use.

comment Event listener for a message/warning box
Files don't display message boxes, applications do. There are other ways to read/write Excel files than by using Excel (especially on a server)

Why do you want to avoid the typical user/password combo?

comment What is a good approach to get a detailed system design from an existing system?
Possibly relevant, hopefully helpful: I've inherited 200K lines of spaghetti code — what now?

comment What is the most sensible design for making files available for download from a URL?
Is it possible to add a virtual directory to your web API that maps to network storage?

comment Is it good to store distance like that?
How often do distances change? (i.e., are your points moving?) How often do you need to look them up?

comment Calling a constructor from a parent class in a derived class
I think your code example may be missing a few "}"s. Can you edit the question and add them? Also, if every line starts with 4 spaces your code will be formatted better.

comment How to detect whether user is actively in the web app?
"... and not on another web site" is a problem - not possible to detect server side. What are you trying to do?

comment Does having a lot of using/import statements indicate bad design or code smell?
Visual Studio has an option to remove unused using statements. You might want to see how many of those 20 are in actual use.

comment Coding style - return object or set exposed properties
In your first example, don't a and a1 refer to the same object?

comment Should <= and >= be avoided when using integers, such as in a For loop?
Author's gender is irrelevant, but I updated my answer anyway. I prefer to select < or <= based on what's most natural for the particular problem I'm solving. As others have pointed out, in a FOR loop < makes more sense in C-type languages. There are other use cases that favor <=. Use all the tools at your disposal, when and where appropriate.

comment Incorporating external web services in Java/Spring web app
What if you had an "internal service layer" and an "external service layer" that were essentially peers of each other?
