Why do std::shared_ptr work
...
shared_ptr<T> logically[*] has (at least) two relevant data members:
a pointer to the object being managed
a pointer to the deleter function that will be used to destroy it.
The deleter function of your shared_ptr<Test>, given the way you constructed...
Is it possible to figure out the parameter type and return type of a lambda?
... template parameters, the actual won't be incorrect, and if it's 0 then at least arg<0> will still exist and you can do with it what you will. If you already plan to not exceed the index arg<arity-1> then it shouldn't interfere with your current implementation.

How do you tell someone they're writing bad code? [closed]
...fensive, pick old code that no one is emotionally attached to any more, at least at the beginning.
As @JesperE: said, focus on the code, not the coder.
When you see something you think should be different, but others don't see it the same way, then start by asking questions that lead to the defi...
Can I find out the return value before returning while debugging in Intellij?
...
Since at least 2016.3, there is a much better way. See answer from Birchlabs for details. It should now be the accepted answer.

Setting Short Value Java
...d here stackoverflow.com/a/27123302/9465588 , JVM did actually serverse at least 32 bits of its virtual memory space per class field, so declaring short fields does not save memory at all. I don't know if Java changed this. I tend to never use short values unless tere's an external restriction invol...
Maximum Length of Command Line String

In Windows 10, it's still 8191 characters...at least on my machine.
It just cuts off any text after 8191 characters. Well, actually, I got 8196 characters, and after 8196, then it just won't let me type any more.
Here's a script that will test how long of a statement yo...
Why does Javascript getYear() return 108?
...00" in honor of this oft-reported non-bug.
Nowadays, in the Perl world at least, it makes more sense to use a standard module for date-handling, one which uses real four-digit years. Not sure what might be available for JavaScript.

How to specialize std::hash::operator() for user-defined type in unordered containers?
...rdered_set and so on. Namely:
Hash type H is a function object, with at least one argument type Key.
H is copy constructible.
H is destructible.
If h is an expression of type H or const H, and k is an expression of a type convertible to (possibly const) Key, then h(k) is a valid expression with t...
How do I execute a command and get the output of the command within C++ using POSIX?
...he child is blocked waiting for stderr to be read. resource deadlock! At least one of those loops would be better as asynchronous (i.e., threaded).

Which, if any, C++ compilers do tail-recursion optimization?
...what collections of compilers do you consider? As pointed out there are at least two compilers that performs optimizations during debug build - and as far as I know VC does that too (except if you're enabling modify-and-continue perhaps).
