What is a reasonable code coverage % for unit tests (and why)? [closed]
... comfortable with. What code I don't test? Technical exception handling, (range/parameter) checks that could be needed. In short, all technical plumbing that I learned to apply from own experience or best practices I read about.

Is the Scala 2.8 collections library a case of “the longest suicide note in history”? [closed]
...ot exactly known for its sophisticated type system. (Although it does have range types, which AFAIK pretty much no other language has, but that isn't really relevant here.) The other three languages I know are BASIC, Smalltalk and Ruby, none of which even have a type system.
And yet, I have no trou...
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...

PHP global in functions

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...
How using try catch for exception handling is best practice

{
return array[index];
}
catch(System.IndexOutOfRangeException e)

You want to partially handle an exception before passing it on for additional handling....
