QUESTION
TL;DR: Why do I name go projects with a website in the path, and where do I initialize git within that path? ELI5, please.
I'm having a hard time understanding the fundamental purpose and use of the file/folder/repo structure and convention of projects/apps in the go language. I've seen a few posts, but they don't answer my overarching question of use/function and I just don't get it. Need ELI5 I guess.
Why are so many project's paths written as:

Answered 2021-Jun-16 at 02:46Why do I name projects with a website in the path?
If your package has the exact same import path as someone else's package, then someone will have a hard time trying to use both packages in the same project because the import paths are not unique. So long as everyone uses a string equal to a URL that they effectively "own", such as your GitHub account (or actually own, such as your own domain), then these name collisions will not occur (excepting the fact that ownership of URLs may change over time).
It also makes it easier to go get your project, since the host location is part of the import string. Every source file that uses the package also tells you where to get it from. That is a nice property to have.
Where do I initialize git?
Your project should have some root folder that contains everything in the project, and nothing outside of the project. Initialize git in this directory. It's also common to initialize your Go module here, if it's a Go project.
You may be restricted on where to put the git root by where you're trying to host the code. For example, if hosting on GitHub, all of the code you push has to go inside a repository. This means that you can put your git root in a higher directory that contains all your repositories, but there's no way (that I know of) to actually push this to the remote. Remember that your local file system is not the same as the remote host's. You may have a local folder called github.com/myname/, but that doesn't mean that the remote end supports writing files to such a location.

QUESTION
TL;DR: Interested in knowing if it's possible to use Abstract Base Classes as a mixin in the way I'd like to, or if my approach is fundamentally misguided.
I have a Flask project I've been working on. As part of my project, I've implemented a "RememberingDict" class. It's a simple subclass of dict, with a handful of extra features tacked on: it remembers its creation time, it knows how to pickle/save itself to a disk, and it knows how to open/unpickle itself from a disk:
...ANSWER
Answered 2021-Jun-15 at 03:43You can get around the problems of subclassing dict by subclassing collections.UserDict instead. As the docs say:
Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it be used for other purposes.
Essentially, it's a thin regular-class wrapper around a dict. You should be able to use it with multiple inheritance as an abstract base class, as you do with AbstractRememberingDict.

As stated above. Under IIS Express on VS2019 I have no issues. When opening the site after deployment to Azure I get:
"The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature."

Answered 2021-Jun-12 at 08:09You have already discovered that tokio::spawn is the correct tool for this task, since you essentially want to use some async code in a "fire-and-forget" way, without waiting for it in the main program flow. You just need a little adjustments to your code.
First, for the error you're quoting - it is due to the fact that you have to somehow handle the possible error during the request. You can simply add question marks after each await returning Result, but then you run into the following:

...ANSWER
Answered 2021-Jun-11 at 14:51In case of problems with valgrind, it is always recommended to try with a recent version, either the last release or the git version.
Note that it is quite easy to recompile valgrind from sources, at it has very few dependencies.
In case of specific problems with stack traces, it is always useful to compare the stack traces produced by valgrind and gdb by using valgrind + gdb + vgdb.
Put a breakpoint in gdb at relevant places, and you can then compare the gdb stacktrace produced by the gdb backtrace command and the valgrind stacktrace produced by the monitoring command:
