I've been trying to make an altered Version of Neel, which uses Jester and adds functionality. After registering some procedures that can be conveniently called from the front-end, you start the Neel app with a macro called startApp, which has this signature:

I have started using my free Azure account and I found out that I cannot create SQL Managed Instance. I get a cryptic error message telling me to change subscription or region, no clear information. The list of free services does not include SQL MI but it does not mean much. SQL Dedicated Pool or Synapse are also not listed but I tried to create them and the Portal does not complain yet even though I did not click the final Create button yet.

I am trying to extract features of an image using SIFT in opencv 4.5.1, but when I try to check the result by using drawKeypoints() I keep getting this cryptic error:

We are developing a Xamarin iOS App and all of the sudden the app starts crashing at some of our logging code in certain places. Apart from the app itself we have an additional xamarin ios library called WKGMobile.IOS containing amongst other things a class called GenericTableViewCell deriving from UITableViewCell. Inside we override UITableViewSource.GetCell(UITableView tableView, NSIndexPath indexPath) and in there we end up calling a virtual method call CellDidLoad which we use in a derived class in our app to initialize some data for our cell and to do some logging. The logging itself however doesn't seem to be the issue as I could replace our complex logging logic with the following pretty meaningless call to new StackTrace():

As a C++ beginner I need your help!

I'm currently working on a program that should be able to read a registry key and its value and write it into a vector array for further processing.

But now I have the problem that umlauts are displayed cryptically in the output on the console. I suspect this is due to the fact that a wrong character encoding is used. After some research I found the function "SetConsoleOutputCP(65001)", which is supposed to set the output of the console to UTF8.

Unfortunately, the output now breaks on umlauts if the Unicode compatible functions were used to read the registry. In the second case the console simply hides the umlauts when using the ANSI compatible functions. What am I doing wrong here and how do I get umlauts correctly read from the registry and output to the console?

Also I would like to write the umlauts correctly into a CSV file later. Do I have to pay attention to anything special here as well?

You can find my code below with some comments. Thanks to all helpers!

I got the following code:

GNU make is generating errors whose root cause is eluding me.

Some brief background: The project is an embedded firmware. We are cross-compiling on a windows host. The build actually runs in the cygwin environment. I have been building the project for some time without any problems. This is a key point. The project was building OK and I have made no changes to the project source or the Makefiles.

A few days ago I installed python3 on my cygwin environment. It had been a while since I ran the Cygwin setup and the setup recommended I update a dozen or so other packages. I accepted the update suggestions without much thought. I did not capture the list of packages or the old versions. I mean, what could go wrong?

Here's what went wrong: the next time I built this project, make failed. The error is cryptic and the root cause is eluding me. I downgraded GNU make from 4.3-1 (the new version) back to 4.2.1-2, but the project still does not build properly.

Here is the error:

When I look up the help page for a specific command, I see it formatted in a cryptic way. For example typing :h x brings up the following:

please consider the following minimal example: I have combined observations from two experiments A and B as a dplyr tibble. llim and ulim define the lower and upper limits of the observable in each group.
