Why shouldn't all functions be async by default?
...s :) I was curious if you could clarify "high latency"? Is there a general range in milliseconds here? I am just trying to figure out where the lower boundary line is for using async because I do not want to abuse it.

Pointers vs. values in parameters and return values
....
If the "large" cutoff seems vague, it is; arguably many structs are in a range where either a pointer or a value is OK. As a lower bound, the code review comments suggest slices (three machine words) are reasonable to use as value receivers. As something nearer an upper bound, bytes.Replace takes ...
std::wstring VS std::string

yes, jalf. c89 specifies minimal ranges for basic types in its documentation of limits.h (for unsigned char, that's 0..255 min), and a pure binary system for integer types. it follows char, unsigned char and signed char have minimum bit lengths of 8. c++ inh...
Does the C++ standard mandate poor performance for iostreams, or am I just dealing with a poor imple
... what it is good for - formatting data into a string. C++ provides a wide range of containers and an ostringstram is amongst the least appropriate for this purpose.
In the case of the vector and ostringstream you get protection from buffer overrun, you don't get that with a char array, and that pr...
Peak signal detection in realtime timeseries data

PHP global in functions
...internet, and its running the massive megasites/apps of innumerable giants ranging from Reuters to Sony, to NYT, to CNN.
And it does it well.
Usage of global keyword inside functions frees Wordpress from MASSIVE bloat which would happen given its huge ecosystem. Imagine every function was asking...
Why does modern Perl avoid UTF-8 by default?
...". Your program appears to work (because the other end usually handles the raw Perl characters correctly), but it is very broken and could stop working at any moment. Fix it with an explicit Encode::encode!
The second problem is UTF-8 encoded source code. Unless you say use utf8 at the top of each ...
How using try catch for exception handling is best practice
... try
{
return array[index];
}
catch(System.IndexOutOfRangeException e)

throw new System.ArgumentOutOfRangeException(
"Parameter index is out of range.");
}
}
You want to partially handle an exception before passing it on for additional handling....
