Miku's answer has since been edited and no longer contains (known) flaws.
Not an exhaustive list.
A valid command in this context means a command that exists. It doesn't matter if the command is used correctly or incorrectly. E.g. man woman would still be considered a valid command, ev...
Practical use of `stackalloc` keyword
...only be stored into a pointer local variable. As of C# 7.2, stackalloc can now be used as part of an expression and can target a span, and that can be done without using the unsafe keyword. Thus, instead of writing

byte* tmp = stackalloc byte[length];
bytes = ne...

...d a weak "use a dereferenced null pointer, get undefined behavior" view.
Now we consider the question.

The Godbolt compiler explorer is designed for nicely formatting...
How do I work with a git repository within another repository?
...MEDIA
git commit -m "Added Media submodule"
Repeat on the other repo...
Now, the cool thing is, that any time you commit changes to MEDIA, you can do this:
cd /path/to/PROJECT2/MEDIA
git pull
cd ..
git add MEDIA
git commit -m "Upgraded media to version XYZ"

How does a “stack overflow” occur and how do you prevent it?
...ite recursive call (given the usual amount of memory in standard computers nowadays).
When you make a call to a method, function or procedure the "standard" way or making the call consists on:
Pushing the return direction for the call into the stack(that's the next sentence after the call)
